Ice & Water Shield Requirements by Jurisdiction
What each jurisdiction’s own sources say about ice barrier (ice & water shield) on residential re-roofs — the conditions are the value. Adjacent cities contradict each other (Denver’s own climate table says No while Aurora’s says Yes), some counties gate the requirement by elevation (above 7,000 ft under Douglas County and the Pikes Peak Regional Building Code), and many cities defer entirely to shingle-manufacturer instructions. The regional split is stark. Every Dallas–Fort Worth authority we checked fills in “No” in its own amended IRC Table R301.2(1) climate criteria — north Texas has no ice-damming history to design for. Kansas splits down the middle of the state: the Kansas City–side suburbs (Overland Park, Olathe, Lenexa, Leawood, Johnson County) all require an ice barrier 24 in. inside the exterior wall line, while Wichita, Sedgwick County, Derby, Haysville, Butler County, Topeka and Shawnee County all answer “None Required” in their own adopted tables. Two roofs 150 miles apart in the same state, opposite answers. Oklahoma works differently again: a statewide amendment (OUBCC, §905.1.2) requires a 36-inch ice barrier in ALL valleys and at ALL changes in roof pitch where the lower roof is shallower — unconditionally, everywhere in the state — on top of whatever each city says about eaves. So in Oklahoma the honest answer is usually “yes in valleys, maybe not at eaves.” Missouri splits the same way Kansas does, east to west: every Kansas City-side jurisdiction we cover answers “Yes” (Kansas City, Independence, Lee’s Summit, Blue Springs, Liberty, Gladstone, Raytown, Grandview, Grain Valley, Belton, North Kansas City, Clay County, Cass County), while every St. Louis-side jurisdiction answers “No” — the City of St. Louis wrote “Ice Shield Underlayment Required: Not Required” into its own amended Table R301.2(1), an explicit decision rather than silence. So the KC metro agrees with itself across the state line while both Kansas and Missouri disagree with their own other halves. Nebraska is the most uniform state we cover: every Omaha/Lincoln-area jurisdiction checked answers “Yes.” The short version for a roofer working the hail belt: assume an ice barrier around Kansas City, assume none in north Texas or around Wichita and St. Louis, and read the card before you bid anywhere in between. Only jurisdictions with an explicit sourced statement appear here. The narrative version, including Colorado’s 7,000-foot elevation gate and Oklahoma’s statewide valley rule, is in the guide: theroofingbook.com/guides/where-code-requires-an-ice-and-water-barrier/.
What the requirement is asking for: Ice and Water Barrier — the material reference, with the governing standard.
Ice barrier required — Colorado (147)
Alamosa County Building Department (Alamosa County, Colorado)
Alamosa County's Table R301.2(1) exhibit lists "Ice barrier underlayment required: YES" as the county's completed determination for unincorporated Alamosa County.
Archuleta County Building Department (Archuleta County, Colorado)
Archuleta County's 2019 building-code resolution (recorded 9/6/2019, reception no. 21905098), Section 2(c) completing IRC Table R301.2(1), prints "Ice Shield Underlayment Required – Yes."
Boulder County - Community Planning & Permitting (Boulder County, Colorado (unincorporated))
County climatic/geographic design-criteria table: "ICE BARRIER UNDERLAYMENT REQUIRED = YES. In accordance with Sections R905.1.2, R905.4.3.1, R905.5.3.1, R905.6.3.1, R905.7.3.1 and R905.8.3.1, where there has been a history of local damage from the effects of ice damming, ice barrier is required." Boulder County's official determination applies this trigger countywide (no elevation threshold).
Central City - Building, Historic Preservation and Planning (City of Central City, Colorado)
Central City Municipal Code § 18-1-20(c) item (7), Table R301.2(1) as filled: "Ice Barrier Underlayment Required: Yes."
Chaffee County Building Safety Department (Chaffee County, Colorado)
Chaffee County Ordinance 2023-02, Exhibit B, amended Table R301.2(1) prints "Ice Barrier Underlayment Required: Yes, per 2021 International Residential Code R905.1.2" as part of the county's climatic and geographic design criteria.
City of Alamosa - Building Department (City of Alamosa, Colorado)
Alamosa's amended IRC Table R301.2(1) (Alamosa Municipal Code § 4-21(2)) lists "Ice barrier underlayment: Yes" as the city's completed determination.
City of Arvada - Building Division (City of Arvada, Colorado)
Ordinance No. 4921 (Council Bill CB26-005), Sec. 18-181, amends Table R301.2(1) of the 2024 IRC, Climatic and Geographical Design Criteria, and fills in the "Ice Barrier Underlayment Required" column as "Yes." The ordinance does not amend IRC Section R905.1.2, so the base 2024 IRC text governs the extent: the ice barrier runs from the lowest edges of all roof surfaces to a point not less than 24 inches inside the exterior wall line of the building (36 inches measured along the slope from the eave edge on roofs of 8:12 or steeper). The city's Roofing and Reroofing Customer Guide (2026) corroborates: "Ice barrier (ice and water shield) is required as specified by the updated code." The city's Re-Roofing Ice Dams Memo of Oct. 1, 2020, which stated that ice barrier was not required as a general rule, predates Ordinance No. 4921 and its 2024 IRC adoption; the city's Reroofing page still links it.
City of Aspen Building Department - Community Development (City of Aspen, Colorado)
Aspen's amended IBC Table 1601.2 (Sec. 8.20.020 item ww) prints "Ice Barrier Underlayment Required = Yes" as the citywide determination (this table is the functional equivalent of IRC Table R301.2(1); Aspen deleted the IRC, per Sec. 8.16.010). The mandate is also stated as operative statute text at Sec. 8.20.020 item uu, amending IBC Sec. 1507.1.2 Ice Barrier: "an ice dam barrier that consists of at least two (2) layers of underlayment cemented together or of a self-adhering polymer modified bitumen sheet shall be used in lieu of normal underlayment and shall extend from the roof eave edge at least six (6) feet inside the exterior wall line as measured along the roof surface, eighteen (18) inches from the centerline of the valley and up twenty-four (24) inches on the vertical wall at a roof and wall juncture."
City of Aurora - Building Division (City of Aurora, Colorado)
City of Aurora Engineering Design Criteria (Public Works Building Division Form #A200, rev. 01/2022, for the 2021 I-Codes) lists "Ice Barrier Underlayment Required: Yes" for the city; per the unamended IRC R905.1.2 baseline this extends from the eave edge to 24 in. inside the exterior wall line on all eaves.
City of Black Hawk - Building Division (City of Black Hawk, Colorado)
Black Hawk Municipal Code § 18-6 item (9), Table R301.2(1) as amended: "Ice Barrier Underlayment Required: Yes."
City of Brush Community Development Department (City of Brush, Colorado)
IRC Table R301.2(1) as filled in by item (8) of Brush Municipal Code § 18-3-30 (Amendments to the International Residential Code, 2018 IRC): "Ice Shield Underlayment Required Yes". The same printed table leaves the Wind Speed, Topographic effects, Special Wind Region, and Windborne Debris Zone cells blank (see wind_design_criteria — left ABSENT for that reason).
City of Centennial - Building Division (City of Centennial, Colorado)
"Ice barrier underlayment water shield is a requirement on all roofs" - stated as a blanket requirement in the city's Residential Roof Repairs and Re-Roofing policy, not limited to eaves only.
City of Cherry Hills Village Building Department (City of Cherry Hills Village, Colorado)
The City's printed Table R301.2 (continuation image) on the Adopted Building Codes page lists "Ice Barrier Underlayment Required: Yes." The City's separate "Specific Roofing Requirements" guide states, under "Ice Dam Protection": "Cherry Hills Village has a history of ice damming in the past. Therefore, in accordance with IRC Section 301.2 an ice barrier is required to be installed in lieu of the regular underlayment and extend from the lowest edges of all roof surfaces in accordance with the above code sections."
City of Commerce City - Building Inspection Division (City of Commerce City, Colorado)
City of Commerce City's locally amended Table R301.2 "CLIMATE GEOGRAPHIC DESIGN CRITERIA" states "Ice barrier underlayment required: Yes" citywide, which triggers the unamended IRC R905.1.2 baseline: ice barrier extends from the lowest edges of all roof surfaces to a point at least 24 in. inside the exterior wall line. This is an adopted building-code requirement that applies even though most residential reroofs are exempt from needing a permit.
City of Cortez - Building Division (City of Cortez, Colorado)
City of Cortez Ordinance No. 1249, Series 2018, Section 2(i) amends Table R301.2(1) to insert "Ice Underlayment Required: Yes." The City's "Building Codes & Design Standards" webpage republishes the same line as "Ice Barrier Underlayment Required: Yes."
City of Craig - Craig/Moffat Regional Building Department (City of Craig, Colorado)
Craig Municipal Code § 15.06.066 (Table R-301.2(1) fill-in, Ord. 1088 §1, 2019): "Ice barrier underlayment required: Yes."
City of Cripple Creek Building Department (City of Cripple Creek, Colorado)
Cripple Creek Municipal Code § 18-4-20's amended Table R301.2(1) prints "ICE BARRIER UNDERLAYMENT REQUIREMENT ... Yes" as one of the added climatic design criteria rows.
City of Dacono - Community Development Department (Building Division) (City of Dacono, Colorado)
Guide states "ICE AND WATER SHIELD IS REQUIRED ON ALL ROOFS" (Wind/Weather Resistance section) — stated as a blanket requirement with no eave-distance or slope condition given.
City of Durango - Building Division (City of Durango, Colorado)
Durango's amended IRC Table R301.2 (§ 6-144) lists "Ice barrier underlayment required: YES" in its own unambiguous single-column cell.
City of Edgewater Building Division (City of Edgewater, Colorado)
Edgewater's own amendment to IRC Table R301.2, Municipal Code Section 18-3-30(6), requires an ice barrier underlayment, which triggers Section R905.1.2's ice-barrier-installation mandate for asphalt shingles and other covered roof types.
City of Englewood - Building Division (City of Englewood, Colorado)
Ice and water shield is required to extend 24 inches inside the exterior wall line of the building.
City of Evans - Building Division (City of Evans, Colorado)
Evans Municipal Code § 15.09.010's fill-in of IRC Table R301.2(1) prints "Yes" in the "Ice barrier Underlayment Required" column.
City of Fort Collins - Building Services (City of Fort Collins, Colorado)
2024 IRC R905.1.2 (unamended, adopted by City of Fort Collins): ice barrier required where Table R301.2 designates it (Fort Collins is designated "Required"); barrier must extend from the lowest roof edge to a point not less than 24 in. inside the exterior wall line (36 in. measured along the slope on roofs pitched 8:12 or greater).
City of Fort Lupton - Building Department (City of Fort Lupton, Colorado)
FAQ states "Yes, ice and water shield barriers & drip edge are required in the City of Fort Lupton" — stated as a blanket requirement; no eave-distance, slope, or elevation condition is given in the FAQ text.
City of Glenwood Springs - Building Department (City of Glenwood Springs, Colorado)
"Ice Barrier Underlayment Required: Yes" (IRC Table R301.2 as printed in City of Glenwood Springs Ordinance No. 06, Series of 2022, Title 060 § 060.030.020).
City of Golden - Building Division (City of Golden, Colorado)
Golden requires an approved ice barrier for all new and re-roofing applications; the barrier must extend from the lowest roof edge to a point no less than 24 inches inside the exterior wall line of the building (per handout: IRC 2024 R905.1.2 / IBC 2024 1507.1.2).
City of Greenwood Village - Community Development (City of Greenwood Village, Colorado)
An ice barrier membrane shall be installed at all eaves directly over the roof deck and extend at least 24 inches inside the exterior wall line. Detached accessory structures without conditioned floor area are exempt.
City of Gunnison Building Department (City of Gunnison, Colorado)
Required, and scoped to where ice dams form rather than across the whole deck. The City of Gunnison fills in the climatic and geographic design criteria table and answers the ice barrier underlayment row with "In roof valleys and eaves".
City of Idaho Springs Building Department (City of Idaho Springs, Colorado)
Idaho Springs Municipal Code § 19-15 item (G), Table R301.2(1) as filled: "Ice Shield Underlayment Required: YES."
City of Lafayette - Building Division (City of Lafayette, Colorado)
Ice and watershield is required (including the eaves and valleys).
City of Lamar Building Department (City of Lamar, Colorado)
"Ice barrier underlayment required Yes" -- IRC Table R301.2 as filled in by Sec. 6-184(a)(7), Amendments to the 2018 IRC (Lamar Municipal Code).
City of Leadville Building Department (Lake County Community Planning & Development) (City of Leadville, Colorado)
Leadville's printed Table R301.2(1) (§ 15.04.030(19)) carries "Ice Barrier Underlayment Required: Yes." Separately, § 15.04.030 items (35)-(41) amend IRC Sections R905.2.7, R905.3.3, R905.4.3.1, R905.5.3.1, R905.6.3.1, R905.7.3.1, and R905.8.3.1 (the material-specific ice-barrier clauses) in identical, universally-applicable language: "In lieu of normal underlayment, an ice barrier that consists of at least two layers of underlayment cemented together or a self-adhering polymer modified bitumen sheet, shall extend from the edge of the eave to a point at least seventy-two (72) inches inside the interior wall line of the building. All valleys shall have at least one (1) thirty-six (36) inch-wide layer applied and shall extend eighteen (18) inches from centerline each way."
City of Littleton - Building and Code Compliance Division (City of Littleton, Colorado)
Ice and water barrier underlayment complying with ASTM D1970, extending a minimum of 2 feet inside the exterior wall line, is required at eaves of all conditioned structures. In valleys: closed valleys require ice and water barrier underlayment at least 36 inches wide; open valleys require one 24-inch-wide galvanized metal layer, or two layers of mineral-surfaced rolled roofing (18 in. and 36 in. wide). Double underlayment or ice and water barrier underlayment is also required where asphalt shingles are installed on a 2/12-4/12 pitch roof.
City of Longmont - Building Inspection Division (City of Longmont, Colorado)
THE CITY'S OWN CODE AND THE CITY'S OWN ROOFING GUIDANCE POINT OPPOSITE WAYS ON THIS, AND A ROOFER NEEDS BOTH. Longmont's roofing guidelines page states: "The City of Longmont does require Ice & Water Shield. Manufacturer's installation instructions and code must be followed; where in conflict the more restrictive applies. Roof slopes between 1/12 and 2/12, above non-habitable space, are permitted to use a bituminous membrane (ice and water guard) then asphalt shingles." That page was read again on 2026-09-10 and still says so. But Longmont Municipal Code Sec. 16.06.160, enacted by Ord. No. O-2026-24 on June 9, 2026, amends Table R301.2 of the International Residential Code and its ICE SHIELD column reads "No" - the row also giving 30 psf ground snow, 110 mph nominal / 142 mph ultimate wind, seismic category B, severe weathering, a 30-inch frost line and a -2 degrees F winter design temperature. So the codified table does not trigger the model code's ice-barrier provision, while the Division that inspects the work says in writing that it requires the membrane. This record publishes true because the City's operational guidance is what an inspector applies and because the City's own conflict rule points to the more restrictive requirement, but it does not decide which of the two governs. Confirm with Building Inspection before pricing a roof without it.
City of Louisville - Building Safety Division (City of Louisville, Colorado)
CARRIED FROM A SOURCE THE CITY HAS REMOVED. The finding (ice barrier required, verified at mid-roof inspection against ASTM D1970 and IRC R905.1.2) came from the City's "Roofing Update and Guidelines" page, deleted in the 2026 site rebuild, and no live City document re-establishes it. The adopting ordinance cannot: Ordinance No. 1907, Series 2025 revises Table R301.2(1) only by pointing at the ASCE hazard tool for loads and publishes no ice-barrier designation, and R905.1.2 conditions the requirement on exactly that table entry. Left as TRUE rather than flipped, because an absent designation is not evidence that no ice barrier is required and Louisville sits in a climate where one ordinarily would be -- but it is unverified and must not be treated as a sourced affirmative until a reader settles it.
City of Loveland - Building Division (City of Loveland, Colorado)
Required on all eaves, installed over the required metal drip edge; not less than 24 in. inside the exterior wall line (36 in. inside for roofs greater than 8:12 pitch).
City of Manitou Springs Planning Department (permits via PPRBD) (City of Manitou Springs, Colorado)
Conditional on elevation, not universal: Section RBC303.4.2 of the 2023 Pikes Peak Regional Building Code prints "Ice Barrier Underlayment Required ... YES" in Table R301.2, with footnote d: "Required only for buildings and structures with a grade plane at or above 7,000 ft (2,134 m) elevation." Manitou Springs sits below 7,000 ft, so this table cell is conditional for most construction in the city (same regional determination documented for the Pikes Peak Regional Building Department itself).
City of Montrose - Building Services (City of Montrose, Colorado)
Montrose Code of Ordinances § 4-1-3(4)'s printed Table R301.2(1) carries the row "ICE BARRIER UNDERLAYMENT REQUIRED" with the printed value "YES."
City of Ouray Community Development - Building Services (City of Ouray, Colorado)
Required city-wide. The City of Ouray's substituted climatic and geographic design criteria table answers "Ice Barrier Underlayment" with "Yes", so the ice barrier provisions of the adopted residential code apply to every roof in the city.
City of Rifle Building Department (City of Rifle, Colorado)
"Ice Shield Underlayment Required Yes" -- IRC/IBC Table R301.2(1) as filled in by Rifle Municipal Code Sec. 18-2-30(3) (Amendments to the 2015 IBC), applied to the Residential Code via Sec. 18-3-30(2).
City of Salida Community Development Department (City of Salida, Colorado)
Required city-wide. The City of Salida amends the climatic and geographic design criteria table, and that table answers "Ice Barrier Underlayment Required" with "Yes, per 2021 International Residential Code R905.1.2".
City of Sheridan Building Department (City of Sheridan, Colorado)
Table R301.2 as amended by § 18-3(j) prints "Ice Shield Underlayment required: Yes." This corroborates the City's own Roofing Requirements page, which independently states: "Ice and water barrier is required on lower roof eaves. The membrane must be installed a minimum of 24" inside the heated space. Unheated areas are exempt."
City of Steamboat Springs - Routt County Regional Building Department (City of Steamboat Springs, Colorado)
City of Steamboat Springs Building Code Ordinance, Sec. 5-5, Table R301.2(1) as amended: "Ice Shield Underlayment Required – Yes per IRC Section R905.1.2 Ice Barriers."
City of Trinidad - Building Department (City of Trinidad, Colorado)
Trinidad's amended IRC Table R301.2 (§ 5-2) lists "Ice barrier underlayment required: Yes" as the city's completed determination.
City of Victor - Building Department (City of Victor, Colorado)
Victor Municipal Code § 18-2-30, item 11's amended Table R301.2(1) prints "Ice Barrier Underlayment Required" as "Yes."
City of Wheat Ridge - Building Division (City of Wheat Ridge, Colorado)
"Ice and Water shield is required at eaves and shall extend a minimum of two (2) feet inside exterior walls."
City of Woodland Park Planning & Building Department (City of Woodland Park, Colorado)
Pikes Peak Regional Building Department's Reroof Guidelines handout states: "Elevations of the property is listed on the permit receipt. Properties that are above 7,000 ft. elevation require an ice barrier to be installed. This barrier shall consist of not fewer than two layers of underlayment cemented together, or a self-adhering, polymer-modified bitumen sheet, and shall extend from the eave's edge to a point of at least 24 inches inside the exterior wall line of the building. (See 2023 PPRBC section RBC303.4.2 Table R301.2 footnote D and 2021 IRC section 905.1.2)" This is elevation-tiered, not a flat regional requirement -- required above 7,000 feet elevation, not required below it; Woodland Park's own townsite sits above that line.
City of Wray - Building Department (City of Wray, Colorado)
Table R301.2's Ice Barrier Underlayment row cross-references R905.1.2 rather than stating Yes/No directly. Ordinance No. 646 replaces R905.1.2 in full: "On roofs with a slope equal to or less than four units vertical in 12 units horizontal (33-percent slope), an ice barrier shall be installed for asphalt shingles, metal roof shingles, mineral-surfaced roll roofing, slate and slate-type shingles, wood shingles and wood shakes. The ice barrier shall consist of not fewer than two layers of underlayment cemented together, or a self-adhering polymer-modified bitumen sheet shall be used in place of normal underlayment and extend from the lowest edges of all roof surfaces to a point not less than 24 inches (610 mm) inside the exterior wall line of the building." This removes the base 2018 IRC's "history of local damage" trigger, making the ice barrier an unconditional requirement for qualifying roof coverings at or below a 4:12 slope.
Clear Creek County Building Department (Clear Creek County, Colorado)
Resolution R-26-19, Table R301.2(1) as amended: "ICE BARRIER UNDERLAYMENT REQUIRED: Yes." Applies to unincorporated Clear Creek County.
Conejos County Land Use Office (Conejos County, Colorado)
The county's printed Table R301.2(1) attachment ("CONEJOS COUNTY, COLORADO ATTACHMENT A") lists the "ICE BARRIER UNDERLAYMENT REQUIRED" column value as "YES."
Craig/Moffat Regional Building Department (Moffat County) (Moffat County, Colorado)
The Craig/Moffat Regional Building Department's Design Criteria page prints, as a row of the jointly-adopted Table R-301.2(1), "Ice barrier underlayment required: Yes."
Douglas County - Building Division (Douglas County, Colorado (unincorporated))
"Ice barrier underlayment is required for elevations above 7,000 feet. Ice barrier shall extend from the lowest edge of all roof surfaces to point at least 24 inches inside the exterior wall line of the building." Not required at elevations of 7,000 feet or below per the same FAQ (elevation-conditional, not universal).
Elbert County Building Department (Elbert County, Colorado)
"Per Ordinance 22-01: Ice Barrier shall be installed for asphalt shingles, metal roof shingles, mineral-surfaced roll roofing, and slate and slate-type shingles." (called out in a red highlight box specific to Elbert County within the county's Single Family Residential Re-roofing guide). Corroborated by the county's Mid/Final Roof Declaration, which requires the installer to declare: "Ice and water shield is installed at eaves, 24" inside the heated wall on all heated buildings in consideration of pitch, buildings attached to heated buildings and buildings with habitable space, per section R905.1.2 of the 2018 IRC Building Code. 90lb felt, or equivalent, or valley metal is installed in valleys."
Fremont County Building Department (Fremont County, Colorado)
Resolution No. 60, Series of 2020, amends Table R301.2(1) of the adopted 2018 IRC for unincorporated Fremont County; the printed cell reads "Ice barrier underlayment required — Yes."
Garfield County Community Development Department (Garfield County, Colorado)
"ICE SHIELD UNDER-LAYMENT REQUIRED -- Yes." (Table R301.2(1) as amended by Garfield County Building Code Resolution of 2017, Resolution No. 2017-23, Exhibit A, Sec. R301 amendment; corroborated by the county's "Building Requirements -- Residential Projects" summary sheet: "Ice Barrier Underlayment: Required.") This is a county-wide requirement, not elevation-tiered like the snow load figures.
Grand County Building Division - Community Development (Grand County, Colorado (unincorporated))
Grand County's Table R301.2(1) amendment prints "ICE BARRIER – YES" as one of the added design-criteria rows. Section R905.1.2 is separately amended to read: "AN ICE BARRIER THAT CONSISTS OF AN APPROVED SELF-ADHERING POLYMER MODIFIED BITUMEN SHEET SHALL BE USED IN LIEU OF NORMAL UNDERLAYMENT ON ALL SLOPED ROOFS. THIS ICE DAM PROTECTION UNDERLAYMENT SHALL BE INSTALLED FROM THE EAVES TO A POINT 6 FEET (1829 mm) INSIDE THE EXTERIOR WALL OF THE BUILDING AND 24 INCHES (610 mm) FROM THE CENTERLINE OF ALL VALLEYS, FULLY ADHERED TO THE SUBSTRATE ON ALL HABITABLE STRUCTURES. Exception: Detached accessory structures not containing conditioned floor area."
Gunnison County Community Development - Building Office (Gunnison County, Colorado)
Gunnison County's Table R301.2 amendment (Resolution 23-22, Attachment B) prints "Ice Barrier Underlayment Required: Yes" as one of the added design-criteria rows.
Huerfano County Land Use and Building Department (Huerfano County, Colorado)
County Resolution 23-25, Section 7, amends IRC Table R301.2 (Climatic and Geographic Design Criteria) and, as printed in the resolution itself, that amended table adds an "Ice Barrier Underlayment Required" column reading "YES (apply to elevations above 6200 ft.)". This is a locally set table entry in the county's own adopted code, which turns on the base IRC's ice-barrier-membrane requirement (Section R905.1.2) for construction above that elevation across unincorporated Huerfano County.
Jackson County Building Inspector (Jackson County, Colorado)
Jackson County's amendment to the 2018 IRC, Section R905.1.2, repeals and reenacts the ice barrier requirement: an approved self-adhering polymer modified bitumen sheet must be used in lieu of normal underlayment on all sloped roofs, installed from the eaves to a point 6 feet inside the exterior wall line and 24 inches from the center line of all valleys, fully adhered to the substrate, on all habitable structures. Detached accessory structures with no conditioned floor area are excepted.
Jefferson County - Building Division (Jefferson County, Colorado (unincorporated))
"Ice barrier shall be installed for asphalt shingles, metal roof shingles, mineral-surfaced roll roofing, slate and slate-type shingles, wood shingles and wood shakes per R905.1.2. Concrete and clay tile per manufacturer's instructions R905.3.8." (2026 county roofing notice does not restate a specific inside-wall distance beyond the R905.1.2 citation.)
La Plata County Community Development Department - Building Division (La Plata County, Colorado)
La Plata County Code Sec. 18-36's Table R301.2 amendment prints "Ice barrier underlayment required" as one of the county's climatic design criteria. The County's own Building Permit Application Packet (revised 2/9/2024) independently lists "Ice barrier underlayment required" as its own bullet under "Climate and Geographic Design Requirements," matching the codified table.
Lake County Community Planning and Development (Lake County, Colorado)
Resolution 2026-20's Table R301.2 prints "Ice Barrier Underlayment Required" as "Yes." Separately, the Resolution's Chapter 9 Roof Assemblies section amends R905.1.2 to read, in relevant part, that "Lake County has" (replacing "areas where there has been") a history of ice forming along eaves, requiring an ice barrier that "shall extend from the lowest edges of all roof surfaces to a point at least" 72 inches (replacing the base code's 24 inches) "inside the interior wall line of the building," and adds that "all valleys shall have at least a 36-inch-wide layer applied and shall extend 18 inches from centerline each way."
Larimer County - Building Division (Larimer County, Colorado (unincorporated))
"Ice Barrier (required county-wide). An ice barrier shall consist of not fewer than two layers of underlayment cemented together or a self-adhering polymer-modified bitumen sheet and shall extend from the lowest edges of all roof surfaces to a point at least two feet inside the exterior wall." Exceptions: metal panel roofs, membrane roof coverings, and detached accessory structures with no heated floor area; existing asphalt shingles with no ice barrier may receive a second layer of roof covering without adding an ice barrier. No elevation threshold is stated — the requirement applies countywide regardless of elevation.
Las Animas County Building Department (Las Animas County, Colorado)
The county's design requirements document states plainly: "ICE BARRIER REQUIRED ABOVE 6,500 FEET" for unincorporated Las Animas County. This is elevation-tiered rather than a flat countywide requirement -- required for construction sites above 6,500 feet elevation, not required below it.
Logan County Planning and Zoning Department (Logan County, Colorado (unincorporated))
The county's "Logan County Roofing Requirements" page states: "Ice barrier is required for asphalt shingles, metal roof shingles, mineral roll roofing, slate, wood shingles, and wood shakes per R905.2.7.1, R905.3.1, R905.4.3.1, R905.6.3.1, R905.7.3.1, R905.8.3.1. Concrete and clay tile per R905.3.4 and R905.3.5 or manufacturer's instructions."
Montrose County Planning and Development - Building Division (Montrose County, Colorado)
Required. Montrose County's building code resolution sets its own climate and geographic design requirements table, and that table answers "Ice Barrier Underlayment Required" affirmatively for the unincorporated county.
Ouray County Land Use Department - Building (Ouray County, Colorado)
Ouray County Resolution No. 2021-049, Exhibit A, item 11, amends Table R301.2(1) to state "Ice Shield: Yes," a county-completed answer to the base 2018 IRC's Section R905.1.2 conditional ice-barrier trigger for areas with a history of ice forming along the eaves.
Pikes Peak Regional Building Department (El Paso County region, Colorado (including Colorado Springs and surrounding municipalities))
Conditional on elevation, not universal: "Properties that are above 7,000 ft. elevation require an ice barrier to be installed. This barrier shall consist of not fewer than two layers of underlayment cemented together, or a self-adhering, polymer-modified bitumen sheet, and shall extend from the eave's edge to a point of at least 24 inches inside the exterior wall line of the building." Elevation is listed on the permit receipt. (See 2023 PPRBC section RBC303.4.2 Table R301.2 footnote D and 2021 IRC section 905.1.2 for application) Below 7,000 ft, no ice barrier is called out for typical reroofs in this handout.
Pitkin County Building Department (Pitkin County, Colorado (unincorporated))
Pitkin County Code Section 11.20.040's amended Table R301.2 lists "Ice Barrier Underlayment Required = YES 905.1.2" as the county-wide determination. The same section separately amends R905.1.2 Ice Barrier as operative text: "An ice dam barrier that consists of at least two layers of underlayment cemented together or of a self-adhering polymer modified bitumen sheet shall be used in lieu of normal underlayment and shall extend from the roof eave edge at least four and one-half feet inside the exterior wall line as measured along the roof surface, twenty-four inches from the centerline of the valley and up twenty-four inches on the vertical wall at a roof and wall juncture."
Rio Blanco County Building Division (Rio Blanco County, Colorado)
The County's Building Codes & Design Criteria page states plainly, among its printed design criteria: "Ice barrier underlayment required."
Rio Grande County Department of Building Safety (Rio Grande County, Colorado)
Rio Grande County's Table R301.2(1) design-criteria exhibit (linked from the Building Department's own "Rio Grande County Design Criteria IRC" document) prints "Ice Barrier Underlayment Required" as "YES."
Routt County Regional Building Department (Routt County, Colorado)
Routt County Un-Incorporated 2021 ICC Building Code Adoption resolution, Table R301.2(1) as amended: "Ice Shield Underlayment Required – Yes per IRC Section R905.1.2 Ice Barriers." Applies to unincorporated Routt County.
San Miguel County Building Department (San Miguel County, Colorado)
San Miguel County's amended IRC Table R301.2(1) (in the same "Amendments to the 2018 International Codes" document) prints an "ICE BARRIER UNDERLAYMENT REQUIRED" column with the value "YES" alongside the county's other climatic design figures. This is separate from the county's Section R328 "Wildfire Resistant Construction" amendment, which requires ignition-resistant roof-covering materials (tested to ASTM E108 or UL 790) -- a fire-class requirement, not an impact-resistance or ice-barrier one, and not used to support this field.
Summit County Building Inspection Department (Summit County, Colorado (unincorporated))
Table R301.2, as amended, prints "Ice Barrier Underlayment Required" as "yes" (footnote h: "In accordance with R905.1 as amended"). Resolution No. 2026-45, Exhibit A amends R905.1.2 Ice Barriers: "An ice dam protection underlayment that consists of an approved self-adhering polymer modified bitumen sheet shall be used with all roof coverings. This ice dam protection underlayment shall extend up the slope of the roof from the drip-edge of the roof or eave and cover the entire roof decking surface."
Teller County Building Division (Teller County, Colorado)
Teller County Building Code, Table R301.2(1) item 8 states: "ICE BARRIER UNDERLAYMENT REQUIRED: An ice barrier is required in Teller County for heated structures and shall be installed per Sections: R905.1.2, R905.2.7.1, R9054.3.1, R905.5.3.1, R905.6.3.1, R905.7.3.1 and R905.8.3.1." The amended Section R905.1.2 states: "In all habitable and/or conditioned structures where there is a potential for ice forming along the eaves causing a backup of water as designated in Table R301.2(1), an ice barrier that consists of at least two layers of underlayment cemented together or of a self-adhering polymer modified bitumen sheet, shall be used in lieu of normal underlayment and extend from the lowest edge of all roof surfaces to a point at least seventy-two (72) inches past the inside of the exterior wall line of the building. All valleys shall be lined with the same ice barrier centered at eighteen inches (18) out from either side of the valley. The addition of electrical service to a detached accessory structure shall not trigger this requirement."
Town of Alma - Building Department (Town of Alma, Colorado)
Alma Municipal Code § 18-1-20(22) (Ord. No. 2025-03, § 1, 6-17-2025) amends IRC Section R905.1.2 to read in its entirety: "R905.1.2 Ice Barriers. An ice dam protection that consists of an approved self-adhering modified bitumen sheet underlayment shall be used at all sloped roofs. This ice dam protection underlayment shall extend up the slope of the roof from the drip edge of the roof or eave and cover the entire roof deck surface. In new construction, ice dam protection shall extend a minimum 30 inches up walls adjacent to the roof surface. Exception: Detached accessory structures that do not contain conditioned space." The same section's Table R301.2(1) separately prints "Ice Barrier Underlayment Required" as "YES," consistent with this text.
Town of Arriba - Building Codes (Town of Arriba, Colorado)
Ordinance No. 154 replaces Section R905.1.2, Ice barriers, with its own provision, conditioned on roof slope rather than the base code's ice-forming-history designation: "On roofs with a slope equal to or less than four units vertical in 12 units horizontal (33-percent slope), an ice barrier shall be installed for asphalt shingles, metal roof shingles, mineral-surfaced roll roofing, slate and slate-type shingles, wood shingles and wood shakes," consisting of "not fewer than two layers of underlayment cemented together, or a self-adhering polymer-modified bitumen sheet," extending from the lowest roof edges to a point not less than 24 inches inside the exterior wall line. The Town's amended Table R301.2 cross-refers to this section rather than stating a flat yes or no.
Town of Avon - Community Development Department (Building Division) (Town of Avon, Colorado)
Town of Avon Municipal Code Sec. 15.10.100, the amended Table R301.2, lists "Ice Barrier Underlayment Required = YES, 100%" as the townwide determination.
Town of Basalt Building Department (Town of Basalt, Colorado)
Basalt's amended Table R301.2(1) (Municipal Code § 18-22, item (7)) prints "Ice Barrier Underlayment Required: Yes."
Town of Bayfield - Building Division (Town of Bayfield, Colorado)
Bayfield Municipal Code § 4-89(4)'s Table R301.2(1) amendment prints "Yes" in the "Ice Shield Underlayment Required" column.
Town of Bennett Building Department (Town of Bennett, Colorado)
Required town-wide, and set by the Town rather than left to the model-code trigger. Bennett Municipal Code Section 18-7-20(10), enacted by Ordinance No. 806-25 on November 4, 2025, completes Table R301.2(1) of the adopted 2024 International Residential Code with the Town's own climatic and geographic design criteria, and the table's Ice Barrier Underlayment Required entry reads YES, with no qualifying footnote or elevation condition. The same table sets a 30 pound ground snow load, a 115 mph wind speed, Seismic Design Category B, severe weathering, a 36 inch frost line depth and a 1 degree Fahrenheit winter design temperature.
Town of Berthoud - Planning and Building Department (Town of Berthoud, Colorado)
"Ice Barrier IS REQUIRED per section R905.1.2" — the Design Criteria table in the same document also lists "Ice Barrier Underlayment Required: Yes."
Town of Blue River - Building Department (Town of Blue River, Colorado)
Blue River's amended Table R301.2(1) (Ordinance No. 2026-01, Sec. 18-2-40 item (12)) prints "Ice Barrier Underlayment Required: YES." The same ordinance separately deletes and rewrites IRC Section R905.1.2, Ice Barriers (Sec. 18-2-40 item (21)): "An ice dam protection that consists of an approved self-adhering modified bitumen sheet underlayment shall be used at all sloped roofs. This ice dam protection underlayment shall extend up the slope of the roof from the drip edge of the roof or eave and cover the entire roof deck surface. In new construction, ice dam protection shall extend a minimum 30 inches up walls adjacent to the roof surface." A parallel IBC Section 1507.1.2 amendment (Sec. 18-2-30 item (11)) adds the same requirement for the Building Code, with an exception for "Detached accessory structures not containing conditioned space."
Town of Bow Mar Building Department (Town of Bow Mar, Colorado)
Table R301.2(1) as amended by § 18-9(b)(1) prints "Ice shield underlayment Requires Yes (See R 905.1.2 Ice Barriers)."
Town of Breckenridge Building Division - Community Development (Town of Breckenridge, Colorado)
Table R301.2(1) as amended by § 8-1-5(A)(21) prints "Ice Barrier Underlayment Required" as "yes" (footnote i: "In accordance with R905.1.1 as amended"). § 8-1-5(A)(40) amends R905.1.2, Ice barriers, to read: "An ice dam protection that consists of an approved self-adhering modified bitumen sheet underlayment, or other similar material that meets the intent and is first approved by the building official, shall be used at all sloped roofs. This ice dam protection underlayment shall extend up the slope of the roof from the drip-edge of the roof or eave and cover the entire roof deck surface. In new construction ice dam protection shall extend a minimum 30 inches up walls and adjacent to the roof surface."
Town of Calhan - Building Code & Permits (Town of Calhan, Colorado)
Calhan's amended Table R301.2(1) (Municipal Code § 6.11.040(F)) prints "Ice Barrier Under-Layment Required: YES."
Town of Carbondale - Building Department (Town of Carbondale, Colorado)
Town of Carbondale Municipal Code Sec. 18-3-20 item (7), amended Table R301.2, lists "Ice Barrier Underlayment Required = Yes" as the townwide determination.
Town of Castle Rock - Building Division (Town of Castle Rock, Colorado)
Per CRMC 15.06.030 (Section R905.1.2, Ice barriers, as amended by Ordinance No. 2026-017, adopted 6/2/2026, effective 6/30/2026): an ice barrier shall be installed on eaves and valleys for asphalt shingles, metal roof shingles, mineral-surfaced roll roofing, slate and slate-type shingles, wood shingles, and wood shakes, consisting of not less than two layers of cemented underlayment or a self-adhering polymer-modified bitumen sheet, extending not less than 24 inches inside the exterior wall line. On roofs with slope 8:12 or greater, the ice barrier must also extend not less than 36 inches up-slope from the eave edge. Exception: detached accessory structures without conditioned floor area.
Town of Cedaredge - Planning & Building Department (Town of Cedaredge, Colorado)
Cedaredge Municipal Code § 15.05.040 ("Manual J design criteria Table R301.2(1) jurisdiction completion") prints the labeled line "Ice Barrier Underlayment: Yes." The companion Table R301.2(1) at § 15.05.030 prints the same field's cell as "Tributary Area Valleys Start Shingles" rather than a Yes/No value -- an apparent drafting artifact in that table -- so this field is sourced to the unambiguous § 15.05.040 statement rather than the garbled table cell.
Town of Columbine Valley Building Department (Town of Columbine Valley, Colorado)
§ 15.08.020(b)(3)'s design-criteria fill-in prints "Ice shield underlayment requires Yes (see Sec. 1507.2.8.2)." This corroborates the Town's own building-codes webpage, which independently states: "Ice barrier shall be used on the eave edge for all new roof tear-offs. The ice barrier shall extend 24 inches from the exterior wall."
Town of Crested Butte Building Department (Town of Crested Butte, Colorado)
Required town-wide. The Town of Crested Butte adds its own climatic and geographic design criteria table, and that table answers "Roof Ice Barrier Underlayment Required" with "Yes", so the ice barrier provisions of the adopted residential code apply to every roof in town.
Town of Dinosaur - Building Permits (Town of Dinosaur, Colorado)
Dinosaur Municipal Code § 12.14.020(VIII)(A)'s filled-in Table R-301.2(1) prints "Ice barrier underlayment required: Yes" as one of the added rows alongside the Town's other climatic design values.
Town of Eagle Building Department (Town of Eagle, Colorado)
The Town of Eagle's Table R301.2(1) amendment (2021 IRC Amendments) prints "Ice Barrier Underlayment: Yes" as one of the filled-in table values, confirmed by reading the rendered table image directly.
Town of Eaton - Building & Permitting (Town of Eaton, Colorado)
IRC Table R301.2(1) as filled in by item (14) of Eaton Municipal Code § 6-1-2 (Amendments to the International Residential Code): "ICE BARRIER UNDERLAYMENT REQUIRED YES".
Town of Fairplay - Building Department (Town of Fairplay, Colorado)
Fairplay Municipal Code § 18-1-20(c) item (9), Table R301.2(1) as filled: "Ice Barrier Underlayment Required: Yes." Item (13) separately rewrites R905.1.2 in full: "An ice dam protection that consists of an approved self-adhering modified bitumen sheet underlayment shall be used at all sloped roofs. This ice dam protection underlayment shall extend up the slope of the roof from the drip edge of the roof or eave and cover the entire roof deck surface. In new construction, ice dam protection shall extend a minimum 30 inches up walls adjacent to the roof surface" -- a universal, non-history-conditional mandate corroborating the table.
Town of Firestone - Building Division (Town of Firestone, Colorado)
R905.1.2. "Ice barriers are REQUIRED. The ice barrier shall extend from the lowest edges of all roof surfaces to a point not less than 24 inches (610 mm) inside the exterior wall line of the building." Mid-roof checklist adds: "Ice & Water installed over the drip on the eaves and underlayment under the drip edge on rakes."
Town of Fraser Building Department (Town of Fraser, Colorado)
Fraser Municipal Code § 18-1-40 item (56) deletes and rewrites R905.1.2: "An ice barrier that consists of an approved self-adhering polymer modified bitumen sheet shall be used in lieu of normal underlayment on all sloped roofs. Roof(s) under 4:12 pitch shall have double underlayment... This ice dam protection underlayment shall be installed from the eaves to a point 6 feet inside the exterior wall line of the building and 24 inches from the center line of all valleys, fully adhered to the substrate on all habitable structures. Exception: Detached accessory structures that contain no conditioned floor area." Item (57) additionally repeals "Sections R905.2.7.1, R905.4.3.1, R905.5.3.1, R905.6.3.1, R905.7.3.1 and R905.8.3.1... in their entirety" -- the base-IRC material-specific "history of local ice damming" trigger clauses -- so the ice-barrier mandate applies universally rather than case-by-case. (Fraser's own Table R301.2(1), item (31), omits the standard "Ice Barrier Underlayment Required" table row entirely; this field is sourced from the operative statute text instead.)
Town of Frederick - Building Department (Town of Frederick, Colorado)
Re-roof guidelines: "Ice and water barrier shall be installed on all roofs." The Design Criteria table on the same page separately lists "Ice barrier requirement - Yes." Mid-Roof Inspection checklist confirms: "All ice and water shield shall be in place."
Town of Frisco - Community Development Department (Town of Frisco, Colorado)
"Ice Barrier Underlayment Required: Yes" (IRC Table R301.2(1) as amended by § 65-3 item (7)), footnote h: "There has been a history of local damage from the effects of ice damming." Corroborated by § 65-3 item (27), which replaces R905.1.2 in its entirety to require an ASTM D1970 self-adhering ice dam protection underlayment on all roof coverings (R905.2 through R905.8, and R905.10), extending up the slope of the roof from the eave a minimum of 8 feet 6 inches inside the exterior wall line (exception: unconditioned detached accessory structures).
Town of Garden City - Building Permits (Town of Garden City, Colorado)
Garden City Municipal Code § 18-2-30(14)'s fill-in of IRC Table R301.2(1) prints "YES" in the "Ice Barrier Under-layment Required" column.
Town of Georgetown Building Department (Town of Georgetown, Colorado)
Required town-wide, with no elevation or roof-slope condition attached. The completed design criteria table in Georgetown Municipal Code Title 15 answers "Ice Shield Underlayment Required" with "YES", so the ice barrier provisions of the adopted International Residential Code apply to every roof in town.
Town of Gilcrest Planning & Zoning Department (Town of Gilcrest, Colorado)
Gilcrest Municipal Code § 18-24(l)'s Table R301.2(1) amendment prints "YES" in the "Ice barrier Underlayment Required" column.
Town of Granby - Building Department (Town of Granby, Colorado)
The town's 2021 IRC amendment ordinance (Chapter 15.05.050, read in full) adds Section R905.1.1 Ice Barrier: an approved self-adhering polymer-modified bitumen ice barrier is required in lieu of normal underlayment on all sloped roofs of habitable structures, installed from the eaves to a point 6 feet inside the exterior wall line and 24 inches from the center line of all valleys, fully adhered to the substrate. Detached accessory structures with no conditioned floor area are exempted.
Town of Grand Lake - Building Permits (Grand County Building Department) (Town of Grand Lake, Colorado)
Grand County's 2015 local amendments, adopted by the Town at Municipal Code Sec. 9-1-2(B), add Section R905.1.2: "An ice barrier that consists of an approved self-adhering polymer modified bitumen sheet shall be used in lieu of normal underlayment on all sloped roofs. This ice dam protection underlayment shall be installed from the eaves to a point 6 feet inside the exterior wall line of the building and 24 inches from the center line of all valleys, fully adhered to the substrate on all habitable structures." The only exception is for detached accessory structures containing no conditioned floor area. The County's completed Table R301.2(1) also states "ICE BARRIER - YES". This requirement is stable across the County's edition change: the corresponding provision in its 2021 amendment package is materially identical.
Town of Green Mountain Falls (Pikes Peak Regional Building Department) (Town of Green Mountain Falls, Colorado)
Conditional on elevation, not universal: Section RBC303.4.2 of the 2017 Pikes Peak Regional Building Code (as amended effective December 7, 2018 -- the edition and printing the Town's own Municipal Code Sec. 18-1 adopts by reference) prints "Ice Barrier Underlayment Required ... YES" in Table R301.2(1), with a footnote: "Required only for buildings and structures with a grade plane at or above 7,000 ft (2,134 m) elevation." The Town straddles El Paso and Teller Counties; elevation determines applicability per the printed footnote, not a townwide flat rule.
Town of Gypsum Building Department (Town of Gypsum, Colorado)
Town of Gypsum Municipal Code Sec. 15.01.040's printed climatic and geographic design criteria table lists "ICE BARRIER AIR UNDERLAYMENT = Yes" as the townwide determination.
Town of Haxtun Building Department (Town of Haxtun, Colorado)
Haxtun Municipal Code section 150.02(B)(8), completing IRC Table R301.2(1) for the Town, states "ICE BARRIER UNDERLAYMENT REQUIRED: YES." Adopted by Ordinance 2025-1, passed October 6, 2025, as part of the Town's 2018 International Residential Code adoption.
Town of Hayden (permits via Routt County Regional Building Department) (Town of Hayden, Colorado)
Town of Hayden 2021 ICC Building Code Adoption resolution, Table R301.2(1) as amended: "Ice Shield Underlayment Required – Yes per IRC Section R905.1.2 Ice Barriers."
Town of Hot Sulphur Springs (Grand County Building Department) (Town of Hot Sulphur Springs, Colorado)
Grand County's building code, adopted by the Town by reference (Resolution 2018-5-31 / Ordinance No. 21, Exhibit A, amending the 2015 International Residential Code), amends Section R905.1.2: "An ice barrier that consists of an approved self-adhering polymer modified bitumen sheet shall be used in lieu of normal underlayment on all sloped roofs. This ice dam protection underlayment shall be installed from the eaves to a point 6 feet inside the exterior wall line of the building and 24 inches from the center line of all valleys, fully adhered to the substrate on all habitable structures." The only exception is for detached accessory structures with no conditioned floor area.
Town of Hotchkiss - Building Permits/Inspections (Town of Hotchkiss, Colorado)
The Town's "Getting Started... A Guide for the Building Process" handout lists among its building requirement reminders: "Ice and water shield is required as a first course as well as in valleys."
Town of Hudson - Building Department (Town of Hudson, Colorado)
The Town's 2021-22 Roofing Regulations handout's Table R301.2(1) lists "Ice Barrier Underlayment Required Yes"; footnote: "*Ice Barrier IS REQUIRED per section R905.1.2."
Town of Ignacio Planning Department (Building Permits) (Town of Ignacio, Colorado)
The Town's own Table 301.2(1), Climatic and Geographic Design Criteria, added by Ordinance 357 Section 5-6(4), sets "Ice Shield Underlayment Required: Yes" for Ignacio. Under the unamended 2018 IRC Section R905.1.2 that this table triggers, "In areas where there has been a history of ice forming along the eaves causing a backup of water as designated in Table R301.2(1), an ice barrier shall be installed," consisting of not fewer than two layers of underlayment cemented together, or a self-adhering polymer-modified bitumen sheet, extending from the lowest roof edges to a point not less than 24 inches inside the exterior wall line, for asphalt shingles, metal roof shingles, mineral-surfaced roll roofing, slate and slate-type shingles, wood shingles and wood shakes.
Town of Johnstown - Building Department (Town of Johnstown, Colorado)
Ice Barrier Requirements: required from the lowest edges of all roof surfaces to a point at least 24 inches inside the exterior wall line.
Town of Keenesburg Building Department (Town of Keenesburg, Colorado)
Keenesburg Municipal Code § 18-1-20(c)(10)'s Table R301.2(1) amendment prints "Ice Barrier Underlayment Required: Yes" as a filled-in row. The Town's separately published Re-Roof requirements sheet confirms in plain language: "Ice Barrier is required. The ice barrier shall extend from the lowest edges of all roof surfaces to a point not less than 24 inches inside the exterior wall line of the building."
Town of Kremmling Building Permits (Town of Kremmling, Colorado)
Required. Kremmling adopts Grand County's building code by reference, and both of the county amendment sets in the adoption chain require an ice barrier: the county's completed climatic and geographic design criteria table answers the ice barrier row affirmatively, and the county's roof-covering amendments carry ice barrier cross-references for asphalt shingles, metal shingles, mineral-surfaced roll roofing, slate, wood shingles and wood shakes alike.
Town of Lake City - Building Permits (Hinsdale County Building Department) (Town of Lake City, Colorado)
The 2015 IRC conditions the ice barrier on a local designation: Section R905.1.2 requires one "In areas where there has been a history of ice forming along the eaves causing a backup of water as designated in Table R301.2(1)," consisting of "not fewer than two layers of underlayment cemented together, or a self-adhering polymer-modified bitumen sheet ... extend[ing] from the lowest edges of all roof surfaces to a point not less than 24 inches inside the exterior wall line of the building," with 36 inches measured along the slope where the roof pitch is 8:12 or greater, and an exception for detached accessory structures not containing conditioned floor area. Hinsdale County, which administers building permits for the Town, makes that designation in its published "Building Planning/Design Criteria (From IRC Table R301.2(1))," which states "Ice Barrier Underlayment: To 24" inside exterior wall." An ice barrier is therefore required here.
Town of LaSalle - Building Department (Town of LaSalle, Colorado)
LaSalle Municipal Code Sec. 18-147(16)'s Table R301.2(1) amendment prints "Ice Barrier Underlayment Required" as "Yes" alongside the town's other climatic design values.
Town of Limon Building Department (Town of Limon, Colorado)
The Town's "Basic Construction Requirements" handout prints: "Ice Barrier on 4/12 or Less from Eves 24" Inside Extension Walls" - i.e. ice barrier underlayment is required on roof slopes of 4:12 or less, extending 24 inches inside the exterior wall line.
Town of Lochbuie - Building Department (permits via SAFEbuilt) (Town of Lochbuie, Colorado)
Required town-wide, with no elevation or roof-slope condition attached. The Town of Lochbuie completed International Residential Code Table R301.2(1) at Municipal Code Section 18-1-20(d), and the table answers "Ice Barrier Underlayment Required" with "YES". The ice barrier provisions of the adopted 2024 International Residential Code therefore apply to every roof in town.
Town of Meeker - Community Development Department (Town of Meeker, Colorado)
The Town of Meeker's local amendment to the 2003 International Residential Code Table R301.2(1), Section 15.5.102, sets "Ice Shield Underlayment Required" to "Yes," alongside a 40 psf ground snow load and an 80 mph wind speed.
Town of Milliken (permits via SAFEbuilt) (Town of Milliken, Colorado)
Required town-wide, with no elevation or roof-slope condition attached. Milliken Municipal Code Section 18-10-20 completes IRC Table R301.2(1) for the Town, and the completed table answers "Ice Barrier Underlayment Required" with "Yes". The ice barrier provisions of the adopted 2024 International Residential Code therefore apply to every roof in town.
Town of Monument (permits via Pikes Peak Regional Building Department) (Town of Monument, Colorado)
PPRBD reroof guidelines: "Elevations of the property is listed on the permit receipt. Properties that are above 7,000 ft. elevation require an ice barrier to be installed. This barrier shall consist of not fewer than two layers of underlayment cemented together, or a self-adhering, polymer-modified bitumen sheet, and shall extend from the eave's edge to a point of at least 24 inches inside the exterior wall line of the building." Confirmed by PPRBD homeowner FAQ: "If the elevation on the property is more than 7,000 feet, ice and water shield is required. If it is below 7,000 feet in elevation, it is not required." Trigger is per-property elevation (shown on the permit receipt), not a town-wide rule.
Town of Morrison Building Department (Town of Morrison, Colorado)
Required town-wide. The Town of Morrison completes the climatic and geographic design criteria table, and that table answers "Ice Shield Underlayment Required" affirmatively, so the ice barrier provisions of the adopted residential code apply to every roof in town.
Town of Mt. Crested Butte Building Division (Town of Mt. Crested Butte, Colorado)
Town of Mt. Crested Butte Ordinance No. 6, Series 2024, Sec. 6-65 amends International Residential Code Section R905.1.2 in its entirety: "Section R905.1.2, Ice Barriers. An ice barrier shall be installed for all roofs. The ice barrier shall consist of a self-adhering polymer-modified bitumen sheet and shall be installed on the entire roof. Exception: Detached accessory structures not containing conditioned floor area." (A parallel IBC-track amendment appears at Sec. 6-31, amending Section 1507.2.8.2, with identical operative text.) This is a local ice-barrier-underlayment mandate under the IRC roof-covering chapter and is distinct from the separately-adopted Colorado Wildfire Resiliency Code's Class A roof-covering (ignition-resistance) requirement, which this record does not use to support impact-resistance or ice-barrier fields.
Town of Nederland Building, Planning & Zoning Department (Town of Nederland, Colorado)
Table R301.2(1) as amended by § 18-2 (embedded table image "8-2.png") prints "Ice Barrier Underlayment Required" as "Yes." No accompanying footnote-definition legend is printed in the codified text beneath the table.
Town of New Castle - Building Department (Town of New Castle, Colorado)
Town of New Castle Municipal Code Sec. 15.10.020's amended Table R301.2 lists "Ice Shield Underlayment Required = Yes" as the townwide determination.
Town of Oak Creek (Routt County Regional Building Department) (Town of Oak Creek, Colorado)
Required. The Town of Oak Creek amends the climatic and geographic design criteria table and answers "Ice Shield Underlayment Required" with "Yes per IRC Section R905.1.2 Ice Barriers", so the ice barrier provisions of the adopted residential code apply to every roof in town.
Town of Ophir - Building Department (Town of Ophir, Colorado)
Table R301.2(1) as amended by Ophir Land Use Code Appendix B (2018 IRC Amendments) prints "Ice Barrier Underlayment Required" as "YES" in its single unbanded design-criteria row.
Town of Orchard City - Building Department (Town of Orchard City, Colorado)
Orchard City's local amendment to the 2018 International Residential Code Table R301.2(1), Climatic and Geographic Design Criteria, sets 'Ice Barrier Underlayment' to 'Yes,' alongside a 30 psf ground snow load and a 115 mph (Ultimate, Exposure C) wind speed.
Town of Pagosa Springs Building Division (Town of Pagosa Springs, Colorado)
Ordinance No. 1034, Series 2026, § 6.13.5, completes IRC Table R301.2(1) (Climatic and Geographic Design Criteria) as adopted with the 2024 IRC: "Ice Shield Underlayment Required: Yes, at permitters per code." The ordinance's own wording is unusual ("permitters" rather than the likely intended "perimeters") but the requirement itself is stated as an unqualified "Yes." Wind speed and ground snow load in the same table are determined per-parcel via the ASCE 7 Hazard Tool rather than a fixed town-wide figure.
Town of Palmer Lake (permits via Pikes Peak Regional Building Department) (Town of Palmer Lake, Colorado)
Required by elevation rather than town-wide. Table R301.2 of the Pikes Peak Regional Building Code lists ice barrier underlayment as required, qualified by footnote d, which limits it to "buildings and structures with a grade plane at or above 7,000 ft (2,134 m) elevation." The trigger is the elevation of the individual property, which the Pikes Peak Regional Building Department prints on the permit receipt.

The Town's completed IRC Table R301.2(1) (Ordinance No. 793-2021, Exhibit A, Chapter 13.60.020, item T) states "Ice Shield Underlayment Required: Yes," so an ice-barrier membrane is required under the Town's adopted Residential Code.
Town of Pierce Building Permit Department (Town of Pierce, Colorado)

The Town of Silt completes International Residential Code Table R301.2(1) in its local amendment list, and the completed table answers "Ice Barrier Underlayment Required" with "Yes". The table footnote carried with it explains the basis: an ice barrier is called for "for areas where the average daily temperature in January is 25F (-4C) or less, or where there has been a history of local damage from the effects of ice damming." The ice barrier provisions of the adopted residential code therefore apply to every roof in town.

Town of Winter Park Building Division (Town of Winter Park, Colorado)
Required, and the Town states the requirement directly in its own amendments rather than through a table cell.

Ice barrier required — Idaho (14)
Bannock County - Planning and Development Services (Bannock County, Idaho)
BANNOCK COUNTY ANSWERS THIS IN ITS OWN TABLE, AND IT ANSWERS WITH A DIMENSION RATHER THAN A YES. Ordinance No. 2020-07 modifies the residential code's Table R301.2(1), Climatic and Geographic Design Criteria, and the County's version carries a column headed "ICE BARRIER UNDERLAYMENT" whose entry is "24 inches". The model table asks only whether an ice barrier underlayment is required and takes a Yes or a No; Bannock instead states a figure, which is the County answering that the barrier applies in the unincorporated county and naming the dimension it wants. Because the County's amendment list does not touch Chapter 9, the ice barrier provisions of the adopted 2018 International Residential Code otherwise apply as written. The table does not say from what point the 24 inches is measured, so confirm the measurement and the required extent up the slope with the Building Division and against the adopted code before ordering material, and check the shingle manufacturer's printed instructions as well. Note that this figure is a Bannock County entry and not a state one: the State of Idaho makes no entry in this table at all, so a neighbouring jurisdiction may well answer differently.
Blaine County - Building Services (Blaine County, Idaho)
THE COUNTY ANSWERS THIS ITSELF AND IT WRITES ITS OWN EXTENT. Blaine County Ordinance 2021-1 replaces Table R301.2(1), Climatic and Geographic Design Criteria, with a table of the County's own. Its column headed ICE BARRIER UNDERLAYMENT REQUIRED reads: "Yes, 24" inside of warm side of exterior wall line". Note what the County changed. The table it repealed in the same ordinance read "Yes, 24" inside of wall line"; the replacement adds "of warm side of exterior". So the County has told you which face of the wall to measure the 24 inches from, and it is the warm side of the exterior wall line. Detail the eave accordingly, and confirm the total extent up the slope against the adopted 2018 International Residential Code and the shingle manufacturer's printed instructions before ordering material, because neither the ordinance nor the table changes the base code's other ice barrier provisions. READ IT WITH THE REST OF THAT TABLE, which is set out under wind design criteria. The winter design temperature the County publishes is -20, and the frost line depth is 32 inches.
City of Blackfoot, Idaho - Building & Safety Department (City of Blackfoot, Idaho)
The City of Blackfoot's own Building & Safety Department publishes the ice barrier requirement directly, on its "Design Loads" page, separately from the codified ordinance: "Ice Barrier Underlayment 24 in (Required)." That page is the City's own published design-criteria table for the 2018 IRC's climatic and geographic design criteria (Table R301.2(1)), which the base code leaves for the adopting jurisdiction to fill in and which Blackfoot's own Title 10, Chapter 2 does not separately print in the codified text. Neither the State of Idaho's amendments to the 2018 IRC (IDAPA 24.39.30.600.03, read in full) nor Blackfoot's own building-code chapter (read in full) modifies or disclaims the base ice-barrier rule at Section R905.1.2. Confirm the 24-inch figure and the eave measurement point with the Building & Safety Department before you bid, since it is published on a department webpage rather than in the codified ordinance.
City of Coeur d'Alene - Building Services Department (City of Coeur d'Alene, Idaho)
YES, and it is sourced from Coeur d'Alene's own design criteria rather than inferred from climate. The City's Building Services department publishes its completed Table R301.2(1), Climatic and Geographic Design Criteria, and under the column headed "ICE BARRIER UNDERLAYMENT REQUIRED" it prints "YES". The same table sets ground snow load 60 psf, weathering Severe, frost line depth 24 inches, winter design temperature -1 degrees F, seismic design category C, termite Slight, air freezing index 809 and mean annual temperature 48.3 degrees F, and the department's separate criteria list gives a design roof snow load of 40 pounds per square foot. The City repeats the requirement on the Reroof Permit form itself: "Ice Barrier underlayment shall be installed per IBC/IRC". How far up the slope the barrier must reach is governed by the adopted 2018 International Residential Code, Section R905.1.2; the State of Idaho does not modify it, since IDAPA 24.39.30.600.03 amends nothing in Chapter 9 of that code, and whether Coeur d'Alene has amended it locally is not established here, so confirm the required extent with Building Services before ordering membrane. Table R301.2(1) is the one part of Part III that Idaho Code 39-4116(4)(c) leaves a city or county free to fill in and amend for local conditions, which is why this answer genuinely differs from one Idaho city to the next. Take it for the address, not for the region: a neighbouring Idaho city completing the same table may print a No.
City of Idaho Falls, Idaho - Building Division (City of Idaho Falls, Idaho)
Sourced from Idaho Falls's own adopted design criteria, not inferred from climate. Idaho Falls City Code 7-6-2(G) amends Table R301.2(1) of the 2018 International Residential Code and prints the City's own values; its "Ice Barrier Reqmnt." column reads "Yes". The rest of that same table is worth having in front of you on an Idaho Falls roof: ground snow load 47, windspeed 90 mph, weathering severe, frost line depth 30 inches, termite slight to moderate, decay none, winter design temperature -6, flood hazards 1955 and October 1986. The City's separately published Building Department Geographic Design Criteria agrees on the numbers it repeats and adds the snow figures it works from: "Ground Snow Load: Pg = 0.10 (4710) = 47.1 PSF" for an elevation of 4,710 feet, a calculated flat roof snow load of 29 psf, and the statement that "Historically, the city has mandated a minimum 30 PSF roof snow load." Idaho's state rule does not answer the ice barrier question either way: IDAPA 24.39.30.600.03 amends nothing in Chapter 9 of the 2018 International Residential Code, and Table R301.2(1) is the one part of Part III that Idaho Code 39-4116(4)(c) leaves a city free to fill in and amend for local conditions. The extent the barrier must reach up the roof slope is governed by the unamended base 2018 IRC text.
City of Ketchum - Building Department (Ketchum, Idaho)
KETCHUM ANSWERS THIS DIRECTLY IN ITS OWN CLIMATIC TABLE, WHICH IS RARE AND WORTH RELYING ON. The City replaces the model Table R301.2(1) with its own, printed in Ketchum Municipal Code section 15.04.020, and the column headed "Ice Barrier Underlayment Required" reads "YES 24" inside of wall line". The neighbouring cells in the same row give a winter design temperature of -20 degrees F, a ground snow load of 120 pounds per square foot, a frost line depth of 32 inches and weathering "Severe". So an ice barrier is required on Ketchum work as a matter of the City's own adopted table, not as an inference from the climate. WHAT THE 24 INCH FIGURE MEANS FOR A CREW. The City's table states the extent as measured inside the exterior wall line rather than from the eave edge, so on a house with a deep overhang the membrane has to run further up the roof than a fixed distance from the edge would give. Measure from the inside face of the exterior wall and work back out. The detailed installation requirements sit in the base 2018 International Residential Code, which is behind the code publisher's paywall; this record does not restate that text. Take the underlayment specification, the lap requirements and the treatment at valleys and low-slope areas from the code itself and from the manufacturer's printed instructions, which the code makes binding. Note also that the City's own R902.2.1 requires a 72 pound mineral surfaced cap sheet underlayment at valleys, which is a separate and additional requirement.
City of Moscow - Community Development Department, Building Division (City of Moscow, Idaho)
Sourced from Moscow's own published design criteria, not inferred from climate. The City's "Design Standards & Adopted Construction Codes" handout, which fills in the residential code's climatic and geographic design table for Moscow, prints the row "Ice Barrier Underlayment Required (roofs)" with the value "Yes". The same handout sets "Ground Snow Load 64 PSF", "Roof Snow Load 40 PSF", "Winter Design Temperature 10 degrees F", "Weathering Damage Severe", "Frost Line Depth 30 inches", "Air Freezing Index 960" and "Mean Annual Temperature 47 degrees F", so the Yes sits in a set of criteria a roofer can sanity-check against the weather on the Palouse. Idaho's state rule does not answer this question: IDAPA 24.39.30.600.03 amends nothing in Chapter 9 of the 2018 International Residential Code, and Table R301.2(1) is the one part of Part III that Idaho Code 39-4116(4)(c) leaves a city or county free to fill in and amend for local conditions. The extent the barrier must reach up the roof slope is governed by the unamended base 2018 IRC text, Section R905.1.2. Other Idaho jurisdictions complete the same table for themselves and may answer differently, so confirm the answer for the address rather than for the state.
City of Mountain Home - Building Services (Mountain Home, Idaho)
THE CITY ANSWERS THIS ITSELF, IN ONE WORD, AND THE ANSWER IS YES. The published Mountain Home design criteria list, under the heading "Mountain Homes Design Criteria", carries the item "Ice Barrier Underlayment - yes". That is the City's own filled-in climatic and geographic design criterion, not an inference from snowfall or latitude, and it is the entry the residential code's ice barrier provision keys off. Read it beside the rest of the same list, which is set out under wind design criteria in this record. WHAT IT DOES AND DOES NOT SETTLE. It settles that an ice barrier underlayment is required on a Mountain Home roof. It does not state how far up the slope the barrier must reach; that is governed by the adopted residential code's own text, which this record does not restate. It also does not displace the shingle manufacturer's printed installation instructions, which the code makes binding and which may call for eave protection beyond the code minimum. Confirm the required extent with the Building Department at 208-580-2091 before ordering membrane, and price the job with the barrier in it rather than as an extra. WHERE THIS ITEM IS PUBLISHED. The design criteria list appears on the City's Land Use and Development page. The building-code list on that same page carries its own date of January 1, 2018 and has been superseded by the City's December 31, 2020 adoption of the 2018 editions; the design criteria block beside it was not restated on the City's newer Building Services page, so a reroofing contractor should confirm the criteria are current when applying.
City of Post Falls - Community Development Department, Building Division (City of Post Falls, Idaho)
Sourced from Post Falls's own climatic and geographic design criteria, not inferred from climate. The City's Current Adopted Codes and Design Criteria sheet states, under Design Criteria: "Ice Shield Underlayment is required because of occasional severe conditions, reference R905.1.2". The same sheet gives weathering as "Severe (see Ice Shield for roofs below)", an air freezing index of 1000 and a mean annual design temperature of 45 degrees. This is a live local difference rather than a formality -- the City of Boise publishes the opposite answer on its own table -- so do not carry another Idaho city's entry to a Post Falls roof. Idaho's state rule does not answer the question either way: IDAPA 24.39.30.600.03 amends nothing in Chapter 9 of the 2018 International Residential Code, and Table R301.2(1) is the one part of Part III that Idaho Code 39-4116(4)(c) leaves a city free to fill in and amend for local conditions. The extent the barrier must reach up the roof slope is governed by the unamended base 2018 IRC text at the section the City's own sheet points to.
City of Rexburg, Idaho - Building Department (City of Rexburg, Idaho)
THE CITY ANSWERS THIS ITSELF, IN ITS OWN CODIFIED TABLE, AND THE ANSWER IS CITY-WIDE. Rexburg City Code Section 15.01.030 replaces Table R301.2(1) of the 2018 International Residential Code with the City's own single table, headed "TABLE R301.2(1) CLIMATIC AND GEOGRAPHIC DESIGN CRITERIA." Its row "Ice Barrier Underlayment Required" carries the value "Yes." That is a city-wide answer and it is not conditioned on elevation, on a map or on a snow zone. Because neither the City's amendments nor the State's touch Chapter 9, the ice barrier provisions of the adopted 2018 International Residential Code apply as written; confirm the required extent up the slope from the eave against that code and against the shingle manufacturer's printed instructions before ordering material.
Elmore County - Land Use and Building Department (Elmore County, Idaho)
ELMORE COUNTY ANSWERS THIS ITSELF, IN THE SAME BREATH AS THE PERMIT QUESTION, WHICH IS RARE. Under "When Is a Building Permit Required?" the County's Land Use and Building Department states: "Roofing permits are required in Elmore County. (Ice Barriers required per R.905.1.2)" That is the County's own published position rather than an inference from climate, and it is the section of the adopted residential code that carries the ice barrier requirement. The extent the barrier must reach up the roof slope is set by the unamended base 2018 IRC text at the section the County itself names; neither Elmore County Code Title 9 Chapter 1 nor the State's amendment list changes it. Do not carry another Idaho jurisdiction's answer onto an Elmore County roof - Idaho leaves the climatic and geographic design criteria table to the local jurisdiction, and Idaho cities and counties give different answers.
Kootenai County - Community Development, Building Division (Kootenai County, Idaho)
THE COUNTY ANSWERS THIS ITSELF, IN ITS OWN TABLE, FOR THE WHOLE UNINCORPORATED COUNTY. Kootenai County Code 7.1.302, as amended by Ordinance No. 608, deletes the model code's Table R301.2(1), Climatic and Geographic Design Criteria, and replaces it with the County's own. The last row of that replacement table is headed "Ice Barrier Underlayment Required" and its entry is "Yes". That is a county-wide answer rather than a per-address one, and it is not conditioned on elevation, a map or a snow zone. Because the County's amendment list does not touch Chapter 9, the ice barrier provisions of the adopted 2018 International Residential Code apply as written; confirm the required extent up the slope from the eave against that code and against the shingle manufacturer's printed instructions before ordering material. Note that this table is where Kootenai differs from a jurisdiction that simply adopts the state code and stops, so a roofer working both inside and outside the cities should not assume a neighbouring city has made the same call.
Latah County - Planning, Building and GIS (Latah County, Idaho)
THE COUNTY ANSWERS THIS ITSELF, IN ITS OWN TABLE, AND THE ANSWER IS COUNTY-WIDE. Latah County Code section 7-1-3(J) completes Table R301.2(1), Climatic and Geographic Design Criteria, of the 2018 International Residential Code for Latah County. Its entry reads "Ice Shield Underlayment Required: Yes". That is not conditioned on elevation, on a map or on a snow zone, unlike the ground snow load in the same table. Because neither the County's amendment list nor the State's touches Chapter 9, the ice barrier provisions of the adopted 2018 International Residential Code apply as written; confirm the required extent up the slope from the eave against that code and against the shingle manufacturer's printed instructions before ordering material. The rest of the County's completed table is set out under wind design criteria.
Madison County - Building Department (Madison County, Idaho)
THE COUNTY ANSWERS THIS ITSELF, IN ITS OWN TABLE, AND THE ANSWER IS COUNTY-WIDE. Madison County's published building regulations, at Section 2-2A, state that "Table R301.2(1) shall be amended to read as follows:" and print a single-row replacement table. Its column headed Ice Barrier Underlayment carries the entry YES. That is a county-wide answer and it is not conditioned on elevation, on a map or on a snow zone. A WARNING ABOUT READING THAT TABLE FROM THE PDF. The table is drawn as a graphic and carries no text layer at all, so copying the document's text, or searching it, returns nothing from the table - the words roof, ice and underlayment each occur zero times in the extracted text of a document whose table plainly contains them. The values here were read from the rendered page. Because neither the County's amendments nor the State's touch Chapter 9, the ice barrier provisions of the adopted 2018 International Residential Code apply as written; confirm the required extent up the slope from the eave against that code and against the shingle manufacturer's printed instructions before ordering material. Read this together with the source caveat under adopted code.
Ice barrier required — Illinois (18)
City of Aurora Building and Permits Division (City of Aurora, Illinois)
REQUIRED BY AURORA'S OWN CLIMATIC TABLE, BUT NOT SEPARATELY INSPECTED. Section 12-17.6 inserts the City's own Table R301.2(1), which answers "Ice Barrier Underlayment Required" with "Yes," so the 2024 IRC's ice-barrier underlayment provision in Chapter 9, which the City does not amend, applies in Aurora. The City's reroofing guide adds: "Is there an inspection for ice and water shield? No, we will only conduct a final roofing inspection, however the code references requirements on ice and water shield." The membrane is required even though no one will look at it before it is covered.
City of Bloomington Building Code Division (Economic & Community Development Department) (City of Bloomington, Illinois)
Bloomington's own Article V insert to Table R301.2(1), the Climatic and Geographic Design Criteria table, reads verbatim: "Ice shield under-layment required = Yes." This is the City's own filled-in table entry, not a base-IRC default.
City of Champaign Building Safety Division (City of Champaign, Illinois)
The City's own amendment package replaces Table R301.2 (Climatic and Geographic Design Criteria) wholesale to fill in Champaign's local values, and the filled row lists "ICE BARRIER UNDERLAYMENT REQUIRED" as YES. The table's own footnote h explains what that means: "In accordance with Sections R905.1.2, R905.4.3.1, R905.5.3.1, R905.6.3.1, R905.7.3.1 and R905.8.3.1, where there has been a history of local damage from the effects of ice damming, the jurisdiction shall fill in this part of the table with 'YES.'" Champaign has made that finding for the whole city.
City of Chicago Department of Buildings (City of Chicago, Illinois)
REQUIRED AT EAVES CITYWIDE FOR SHINGLE, SLATE AND SHAKE ROOFS. Chicago rewrites the first sentence of IBC Section 1507.1.2 (Municipal Code 14B-15-1507, item 2) to read "At eaves, an ice barrier shall be installed for asphalt shingles, metal roof shingles, mineral-surfaced roll roofing, slate and slate-type shingles, wood shingles and wood shakes." The requirement is stated without any local-climate condition. The materials and how far the barrier runs up the roof are the rest of the 2018 IBC section, which Chicago does not change. A roof replacement may leave an existing ice barrier membrane that is adhered to the deck in place and cover it with a new layer of ice barrier (Rehabilitation Code Section 14R-3-306.3, Exception).
City of Decatur Building Inspections Division (City of Decatur, Illinois)
Enacted by the City itself. Chapter 67.2, Section 8(c) amends Table R301.2 to add, verbatim, "Ice Barrier underlayment required, yes," alongside the other climatic and geographic design criteria the City filled in for its jurisdiction.
City of Elgin, Illinois Community Development Department (City of Elgin, Illinois)
ELGIN WRITES ITS OWN CLIMATIC TABLE RATHER THAN LEAVING IT BLANK, AND THE ANSWER IS YES. Section 16.36.020 amends Table R301.2 (Climatic and Geographic Design Criteria) "by adding the following entries," including "Ice Barrier Underlayment Required = Yes." The same table entries give Ground Snow Load 30 lbs per square foot, Wind Design Speed 115 mph, and Seismic Design Category A. Illinois supplies no statewide climatic table of its own to default to or override; the requirement rests entirely on Elgin's own adopted table. What the ice barrier must be made of and how far up the slope it must run is base 2021 IRC content (Section R905.1.2) that Elgin's amendment section does not modify.
City of Evanston Building and Inspection Services Division (City of Evanston, Illinois)
REQUIRED BY EVANSTON'S OWN INSERTED CLIMATIC TABLE, IN PLAIN WORDS. Ordinance 29-O-22, Exhibit G amends Table R301.2 Climatic and Geographic Design Criteria and inserts the City's own row values, including "Ice Barrier Underlayment Required: Yes" printed directly in the table alongside a ground snow load of 30 psf and a wind speed of 117 mph. That is a first-party, jurisdiction-specific answer inserted into the adopted code itself, not an inference from a geographic default.
City of Joliet Building and Inspectional Services Division (City of Joliet, Illinois)
REQUIRED AT EVERY EAVE AND VALLEY, IN THE CITY'S OWN WORDS. The City's published interpretation of its Building Code reads, in full: "Underlayment shall be of an approved type. Ice and water shield shall be properly installed along all eave edges and in all valleys." The page states this as the City's own reading of the adopted 2015 International Building Code and gives no exception by roof pitch or by prior installation history.
City of Naperville Building Permits (Transportation, Engineering and Development Business Group) (City of Naperville, Illinois)
REQUIRED BY THE CITY'S OWN CLIMATE TABLE. Naperville's local Table R301.2 in Section 5-1B-2 answers "Yes" under "Ice Barrier Underlayment Required," which switches on the base 2024 IRC's ice barrier provision for asphalt shingles in Section R905 (cited as a pointer only). The amendment states no exception by pitch or by roof type.
City of Springfield, Illinois - Office of Public Works, Building and Zoning Division (City of Springfield, Illinois)
Springfield's own local amendment to IRC Table R301.2(1), Section 170.10.03(f), states verbatim: "ICE SHIELD UNDERLAYMENT IS REQUIRED." This is a city-enacted requirement, not a restatement of a state default (Illinois has none - see adopted_code).
City of Waukegan Building & Code Department (City of Waukegan, Illinois)
REQUIRED, AND THE CITY GIVES TWO CONSISTENT ANSWERS. The Roofing permit page's own "ADDITIONAL ROOFING REQUIREMENTS" state plainly: "MINIMUM OF 24" OF ICE AND WATER SHIELD IS REQUIRED." Separately, the City's local Table R301.2(1) (Sec. 6-402, Ord. No. 22-O-44) inserts "Ice Barrier Underlayment Required ... Yes" alongside a Ground Snow Load of 30 and a Winter Design Temperature range of 68 degrees F to -10 degrees F. Neither document ties the requirement to eave overhang or roof pitch; the 24-inch figure is the City's own stated minimum width.
Rockford Building and Development Services (City of Rockford, Illinois)
The City's own Table R301.2(1), as adopted at Section 105-85 item (19), prints "Ice Barrier Underlayment Required: YES" for Rockford. Ground snow load is listed as 30 pounds per square foot and winter design temperature as -4°F on the same table.
Village of Arlington Heights Building and Life Safety Department (Village of Arlington Heights, Illinois)
The Village's own local amendment to Table R301.2(1), Climatic and Geographic Design Criteria (Section 23-202), inserts the entry "Ice Barrier Underlayment Required" as "Yes." The Village's Statement of Acknowledgement for residential asphalt shingle re-roofing adds that roof extensions must be underlayed with ice/water shield to a point two feet past the inside of the wall, and valleys require a three-foot-wide ice/water underlayment strip.
Village of Bolingbrook Building Division (Village of Bolingbrook, Illinois)
REQUIRED BY THE VILLAGE'S OWN INSERTED CLIMATIC TABLE. Section 10-60(7) of the Village Code inserts the Village's values into Table R301.2(1) Climatic and Geographic Design Criteria of the 2018 International Residential Code, including "Ice Shield Underlayment: Yes," alongside a ground snow load of 30 and a wind speed of 115 mph. This answer reflects the code in force before January 1, 2027; the Village's 2024 local amendments taking effect that day are not reflected here.
Village of Oak Lawn Building Division (Village of Oak Lawn, Illinois)
REQUIRED, IN THE VILLAGE'S OWN WRITTEN WORDS. The Village's Roofing Permit Requirements sheet (undated, read October 3, 2026) states: "In Oak Lawn section R905.1.2, all residents shall be provided with an ice & water barrier. The ice barrier shall consist of not fewer than two layers of underlayment cemented together, or a self-adhering polymer modified bitumen sheet shall be used in place of normal underlayment and extend from the lowest edges of all roof surfaces to a point not less than 24 inches inside the exterior wall line of the building. On roofs with slope equal to or greater than eight units vertical in 12 units horizontal (67-percent slope), the ice barrier shall also be applied not less than 36 inches measured along the roof slope from the eave edge of the building." This record rests on that statement by the department that issues the permit; the Village's enacted climatic table or amendment text is not quoted here.
Village of Oak Park Permits and Development Division (Village of Oak Park, Illinois)
REQUIRED BY THE VILLAGE'S ROOFING GUIDELINES. "An ice barrier is required and must extend from the lowest roof point to a point at least 24 inches inside the exterior wall line of the building. In most cases this will require 2 rows be installed before continuing with other underlayment options." The guidelines add: "Detached accessory structures (shed / garage) are exempt from this unless they are conditioned spaces. (Furnace / AC / Radiant Heat)"
Village of Palatine Building Permits & Inspections (Village of Palatine, Illinois)
REQUIRED BY THE VILLAGE'S OWN CLIMATIC TABLE. Sec. 6-2.2 of the Code of Ordinances amends 2021 IRC Table R301.2(1) (Ord. No. O-111-24, 12/02/2024), and the inserted table answers "YES" in its "Ice Barrier Underlayment Required" column. The 2026 Single Family Re-Roof Handout states the rule for re-roofs: "Ice protection. An ice barrier that consists of at least two layers of underlayment cemented together or of a self-adhering polymer modified bitumen sheet, shall be used in lieu of normal underlayment and extend from the eave's edge to a point at least 24 inches inside the exterior wall line of the building." The handout also says "Roof slopes from 2:12 to 4:12 slopes shall have double underlayment applied in accordance with table R905.1.1(2) of the 2021 International Residential Code."
Village of Schaumburg Community Development Department (Village of Schaumburg, Illinois)
Section 153.03(M) fills in the 2021 IRC's Table R301.2(1), Climatic and Geographic Design Criteria, for Schaumburg and states outright: "Ice Barrier Underlayment Required?: Yes."
Ice barrier required — Indiana (34)
Allen County Building Department (building-permit and contractor-licensing authority for the City of Fort Wayne, Indiana) (City of Fort Wayne, Allen County, Indiana)
STATE-GOVERNED, and categorically YES for Fort Wayne -- this is one of the places where Allen County's answer differs from central Indiana's. Indiana's replacement TABLE R301.2(1) at 675 IAC 14-4.4-5 pre-fills the "ICE SHIELD UNDERLAYMENT REQUIRED" column as YES for Allen County, which makes the ice barrier a flat requirement for asphalt-shingle re-roofs in Fort Wayne rather than a manufacturer-instruction-dependent one. The Indiana State Building Commissioner's guidance memo "Ice/Water Shield & Metal Drip Edge in Class 2 Construction with Asphalt Shingles" (Craig E. Burgess, AIA NCARB CPE CBI LEED AP, dated 2020-02-25) sets out the two-layer structure explicitly: "there are specific counties in which it is always required (per Table R301.2(1)), and specific counties in which it is required only when the roofing manufacturer's written installation instructions require it (per Sections R903.1, R904.1 and R905.1)." Allen County is in the first group. The governing installation-extent provision is IRC Section R905.1.2, adopted by Indiana without substantive amendment, which requires the ice barrier to consist of not fewer than two layers of underlayment cemented together or a self-adhering polymer-modified bitumen sheet, extending from the lowest edges of all roof surfaces to a point not less than 24 inches inside the exterior wall line of the building, with an exception for detached accessory structures not containing conditioned floor area. Note that this is a state code requirement that no local permit practice can switch off -- Indiana DHS states that the 2020 Indiana Residential Code governs all Class 2 residential construction "[r]egardless of any established local enforcement policies or practices to the contrary."
Allen County, Indiana Building Department (Allen County, Indiana)
REQUIRED IN ALLEN COUNTY, AND IN INDIANA THIS IS A COUNTY-BY-COUNTY ANSWER RATHER THAN A STATE ONE. Indiana throws out the model climatic table and substitutes its own: 675 IAC 14-4.4-5 directs "Delete TABLE R301.2(1) and the corresponding footnotes and substitute to read as follows," and the substituted table then runs one row for each of the 92 counties. The Allen County row, numbered 02, reads Yes in the column headed "Ice Shield Underlayment Required." Allen is one of only 27 Indiana counties that answer Yes, all of them in the northern tier; the other 65 answer No. A rule of thumb carried up from central or southern Indiana is therefore wrong here, and so is any assumption that Indiana has one statewide answer. The rest of the Allen County row: wind speed 115 mph, Seismic Design Category A, ground snow 20 psf, frost depth 36 inches, winter design temperature 1 degree Fahrenheit, decay Slight to Moderate, termite Moderate to Heavy, weathering Severe, air freezing index 2000, mean annual temperature 49.9 degrees Fahrenheit. What the ice barrier has to be made of, and how far up the slope it has to run, is base International Residential Code content that Indiana does not modify. The state rule was read in full and carries no ice barrier language of its own, so take the specification from the adopted 2018 edition rather than from a neighbouring state. Allen County adds nothing either: Title 6 and the Building Department Rules and Regulations were read in full and contain no ice barrier or underlayment provision.
Angola Building Safety Department (City of Angola, Indiana)
REQUIRED BY THE STATE TABLE FOR STEUBEN COUNTY, AND THIS IS THE ANSWER MOST INDIANA RECORDS IN THIS BOOK DO NOT GIVE. The Steuben County row of Table R301.2(1) in the 2020 Indiana Residential Code, as substituted by 675 IAC 14-4.4-5, reads ice shield underlayment required Yes. That row was read from the rendered table rather than from extracted text, because the table's termite column drops out of extraction and every column to its right then reads one place out. WHAT THE Yes MEANS, IN THE STATE'S OWN WORDS. The State Building Commissioner's memo distinguishes counties where the barrier is always required from "specific counties in which it is required only when the roofing manufacturer's written installation instructions require it". Steuben County is in the first group, so the ice barrier is required on an asphalt shingle roof here regardless of what the shingle manufacturer's instructions say, and regardless of whether the job needs a building permit. Section R905.1.2 states the trigger in the code's own terms: "In areas where there has been a history of ice forming along the eaves causing a backup of water as designated in Table R301.2(1), an ice barrier shall be installed for asphalt shingles, metal roof shingles, mineral-surfaced roll roofing, slate and slate-type shingles, wood shingles and wood shakes." DO NOT CARRY THIS ACROSS THE STATE. Neighbouring Indiana counties answer differently, and several counties in this book read No on the same table. Angola's Chapter 15.10 says nothing either way: "ice barrier", "ice and water" and "ice shield" each occur zero times across all thirty two sections.
City of Crown Point, Indiana - Building Department (City of Crown Point, Indiana)
REQUIRED IN LAKE COUNTY, ALWAYS - THIS IS ONE OF THE TWENTY-SEVEN "YES" COUNTIES. Indiana deletes the model climatic table and substitutes its own: 675 IAC 14-4.4-5 directs "Delete TABLE R301.2(1) and the corresponding footnotes and substitute to read as follows", and the substituted table runs one row per county. Row 45 is Lake, and it carries "Yes" in the column headed "Ice Shield Underlayment Required". Twenty-seven of Indiana's ninety-two counties carry "Yes" there and they are the northern tier; the other sixty-five carry "No". The rest of the Lake County row is the northern Indiana set - wind speed 115 mph, seismic design category A, ground snow 30 psf, foundation depth 36 inches, winter design temperature 1 degree F, weathering Severe, air freezing index 2000, mean annual temperature 49.0 degrees F. Neighbouring Porter and LaPorte read "Yes" as well, so the whole lakeshore corridor is consistent. WHY THE DISTINCTION MATTERS ON A QUOTE: the State Building Commissioner explains that in a "No" county the barrier is required only where the shingle manufacturer's written installation instructions call for it, while in a "Yes" county it is required by the table itself - "there are specific counties in which it is always required (per Table R301.2(1)), and specific counties in which it is required only when the roofing manufacturer's written installation instructions require it". Crown Point is in an always-required county, so it goes on every asphalt shingle re-roof regardless of what the shingle wrapper says. WHAT THE BARRIER HAS TO BE, from the version of the section actually in force, published first-hand by the Indiana State Building Commissioner on Indiana Department of Homeland Security letterhead in the Ice/Water Shield and Metal Drip Edge guidance of February 25, 2020: "In areas where there has been a history of ice forming along the eaves causing a backup of water as designated in Table R301.2(1), an ice barrier shall be installed for asphalt shingles, metal roof shingles, mineral-surfaced roll roofing, slate and slate-type shingles, wood shingles and wood shakes. The ice barrier shall consist of not fewer than two layers of underlayment cemented together, or a self-adhering polymer-modified bitumen sheet shall be used in place of normal underlayment and extend from the lowest edges of all roof surfaces to a point not less than 24 inches (610 mm) inside the exterior wall line of the building. On roofs with slope equal to or greater than eight units vertical in 12 units horizontal (67-percent slope), the ice barrier shall also be applied not less than 36 inches (914 mm) measured along the roof slope from the eave edge of the building." The section carries one exception: "Detached accessory structures not containing conditioned floor area." So a detached unheated garage in Crown Point is outside it, and a heated one is not.
City of Elkhart, Indiana - Permit Center / Building Division (City of Elkhart, Indiana)
REQUIRED IN ELKHART COUNTY. This is a county-by-county answer in Indiana and it is the field most often got wrong here by carrying over an answer from a job further south. The state deletes the model climatic table and substitutes its own: 675 IAC 14-4.4-5 directs "Delete TABLE R301.2(1) and the corresponding footnotes and substitute to read as follows," and the substituted table runs one row per county. Row 20 is Elkhart, and it carries "Yes" in the column headed "Ice Shield Underlayment Required". Twenty-seven of Indiana's ninety-two counties carry "Yes" there and they are the northern tier; the other sixty-five carry "No", so an answer brought up from Indianapolis or Carmel would be wrong in Elkhart. The rest of the Elkhart County row is the northern Indiana set: wind speed 115 mph, seismic design category A, ground snow 30 psf, frost depth 36 inches, winter design temperature 1 degree F, weathering Severe. Neighbouring St. Joseph County reads "Yes" as well, so the Elkhart to South Bend corridor is consistent on this point. Elkhart has no power to change it: IC 22-13-2-3(c) bars a city, town or county from an ordinance more stringent or detailed than the state rules. Two practical additions. The Indiana State Building Commissioner points out that even in a "No" county the barrier can still be mandatory because Sections R903.1, R904.1 and R905.1 require roofing materials to be installed to the manufacturer's instructions - "there are specific counties in which it is always required (per Table R301.2(1)), and specific counties in which it is required only when the roofing manufacturer's written installation instructions require it (per Sections R903.1, R904.1 and R905.1)" - so in Elkhart both routes point the same way. And Elkhart inspects it: the City's list of required building inspections includes an "Ice & Water Shield/TPO/Metal Roof Inspection", so leave it exposed until that call is made.
City of Gary, Indiana - Building Department (City of Gary, Indiana)
Gary is in Lake County, and Lake County is one of the 27 Indiana counties where the ice barrier is required outright. Indiana deletes the model IRC Table R301.2(1) and substitutes its own county by county table at 675 IAC 14-4.4-5; the Lake County row states "Yes" in the column headed "Ice Shield Underlayment Required". This is a per county answer and not a state one. Most Indiana counties, Marion (Indianapolis) and Hamilton (Carmel) among them, are marked "No" and get an ice barrier only where the shingle manufacturer's written instructions call for one. A roofer who works both ends of Indiana should not carry the central Indiana answer north to Gary.
City of Goshen, Indiana - Building Department (City of Goshen, Indiana)
REQUIRED IN ELKHART COUNTY. This is a county-by-county answer in Indiana and it is the field most often got wrong here by carrying an answer up from a job further south. The state deletes the model climatic table and substitutes its own: 675 IAC 14-4.4-5 directs "Delete TABLE R301.2(1) and the corresponding footnotes and substitute to read as follows", and the substituted table runs one row per county. Row 20 is Elkhart, and it carries "Yes" in the column headed "Ice Shield Underlayment Required". Twenty-seven of Indiana's ninety-two counties carry "Yes" there and they are the northern tier; the other sixty-five carry "No". The rest of the Elkhart County row is the northern Indiana set: wind speed 115 mph, seismic design category A, ground snow 30 psf, foundation depth 36 inches, winter design temperature 1 degree F, weathering Severe. Neighbouring St. Joseph and LaGrange Counties read "Yes" as well, so the whole Goshen to South Bend corridor is consistent on this point. Goshen has no power to change it: IC 22-13-2-3(c) bars a city, town or county from an ordinance more stringent or detailed than the state rules. The Indiana State Building Commissioner adds the point that matters in a "No" county and is worth knowing here too - Sections R903.1, R904.1 and R905.1 require roofing materials to be installed in accordance with the manufacturer's installation instructions, so "there are specific counties in which it is always required (per Table R301.2(1)), and specific counties in which it is required only when the roofing manufacturer's written installation instructions require it (per Sections R903 .1, R904.1 and R905 .1)." In Elkhart County both routes point the same way.
City of Hammond, Indiana - Inspections Department, Building Division (City of Hammond, Indiana)
Hammond is in Lake County, and Lake County is one of the 27 Indiana counties where the ice barrier is required outright. Indiana deletes the model IRC Table R301.2(1) and substitutes its own county-by-county table at 675 IAC 14-4.4-5; the Lake County row states "Yes" in the column headed "Ice Shield Underlayment Required". This is a per-county answer, not a state one - most Indiana counties, including Marion (Indianapolis) and Hamilton (Carmel), are marked "No" and get an ice barrier only where the shingle manufacturer's written instructions call for one. A roofer working both ends of Indiana should not carry the central-Indiana answer north.
City of Hobart, Indiana - Building Department (City of Hobart, Indiana)
REQUIRED IN LAKE COUNTY, ALWAYS - THIS IS ONE OF THE TWENTY-SEVEN "YES" COUNTIES. Indiana deletes the model climatic table and substitutes its own: 675 IAC 14-4.4-5 directs "Delete TABLE R301.2(1) and the corresponding footnotes and substitute to read as follows", and the substituted table runs one row per county. Row 45 is Lake, and it carries "Yes" in the column headed "Ice Shield Underlayment Required". Twenty-seven of Indiana's ninety-two counties carry "Yes" there and they are the northern tier; the other sixty-five carry "No". The rest of the Lake County row is the northern Indiana set - wind speed 115 mph, seismic design category A, ground snow 30 psf, foundation depth 36 inches, winter design temperature 1 degree F, weathering Severe, air freezing index 2000, mean annual temperature 49.0 degrees F. Neighbouring Porter and LaPorte read "Yes" as well, so the whole lakeshore corridor is consistent. WHY THE DISTINCTION MATTERS ON A QUOTE: the State Building Commissioner explains that in a "No" county the barrier is required only where the shingle manufacturer's written installation instructions call for it, while in a "Yes" county the table itself requires it - "there are specific counties in which it is always required (per Table R301.2(1)), and specific counties in which it is required only when the roofing manufacturer's written installation instructions require it". Hobart is in an always-required county. WHAT THE BARRIER HAS TO BE, from the version of the section actually in force, published first-hand by the Indiana State Building Commissioner on Indiana Department of Homeland Security letterhead in the Ice/Water Shield and Metal Drip Edge guidance of February 25, 2020: "In areas where there has been a history of ice forming along the eaves causing a backup of water as designated in Table R301.2(1), an ice barrier shall be installed for asphalt shingles, metal roof shingles, mineral-surfaced roll roofing, slate and slate-type shingles, wood shingles and wood shakes. The ice barrier shall consist of not fewer than two layers of underlayment cemented together, or a self-adhering polymer-modified bitumen sheet shall be used in place of normal underlayment and extend from the lowest edges of all roof surfaces to a point not less than 24 inches (610 mm) inside the exterior wall line of the building. On roofs with slope equal to or greater than eight units vertical in 12 units horizontal (67-percent slope), the ice barrier shall also be applied not less than 36 inches (914 mm) measured along the roof slope from the eave edge of the building." The section carries one exception: "Detached accessory structures not containing conditioned floor area." So a detached unheated garage in Hobart is outside it, and a heated one is not. The guidance also warns that the barrier is a code matter and the warranty is not: "It is not the building code official's responsibility, however, nor is it the responsibility of this office, to enforce provisions of any manufacturer's or installer's warranty".
City of Huntington Community Development & Redevelopment Department (City of Huntington, Indiana)
REQUIRED IN HUNTINGTON COUNTY BY THE STATE TABLE, AND THE CITY SAYS SO ON ITS OWN FORM. Table R301.2(1) of the Indiana Residential Code runs county by county, and the Huntington row reads Ice Shield Underlayment Required: Yes. The Indiana Department of Homeland Security's guidance explains the effect: "In short, there are specific counties in which it is always required (per Table R301.2(1))". Its reproduction of section R905.1.2 applies the ice barrier to asphalt shingles and other listed coverings, running to a point not less than 24 inches inside the exterior wall line, and exempts detached accessory structures not containing conditioned floor area. The City's Roof Alteration permit form states the local practice for permitted work: "Ice & water shield is required to be installed on all primary structure roof alterations and on accessory structure roof alterations if heated."
City of La Porte Engineering & Building Department (City of La Porte, Indiana)
REQUIRED IN LaPORTE COUNTY, AND THE CITY SAYS ITS ROOFING INSPECTION CHECKS IT. Indiana deletes the model climatic table and substitutes its own county-by-county table at 675 IAC 14-4.4-5. Row 46, LaPorte, carries Yes in the Ice Shield Underlayment Required column; 27 of the state's 92 county rows do. The State Building Commissioner's guidance, on Indiana Department of Homeland Security letterhead, reproduces the adopted Section R905.1.2: "In areas where there has been a history of ice forming along the eaves causing a backup of water as designated in Table R301.2(1), an ice barrier shall be installed for asphalt shingles, metal roof shingles, mineral-surfaced roll roofing, slate and slate-type shingles, wood shingles and wood shakes. The ice barrier shall consist of not fewer than two layers of underlayment cemented together, or a self-adhering polymer-modified bitumen sheet shall be used in place of normal underlayment and extend from the lowest edges of all roof surfaces to a point not less than 24 inches (610 mm) inside the exterior wall line of the building." On roofs of 8 in 12 slope or steeper the barrier must also run at least 36 inches up the slope from the eave edge, and the one exception is "Detached accessory structures not containing conditioned floor area." The 24 inches is measured inside the exterior wall line, not from the eave, so a deep overhang pushes the barrier further up the roof than a single 36 inch course may reach. On the local side, the City's Roofing Permit description lists Ice and Water Shield among the items a roofing inspection covers. La Porte has no ordinance of its own on the barrier and could not vary the state rule under IC 22-13-2-3(c).
City of Logansport Building Department (City of Logansport, Indiana)
REQUIRED IN CASS COUNTY BY THE STATE TABLE ITSELF, NOT ONLY WHERE THE MANUFACTURER CALLS FOR IT. Indiana's amended Table R301.2(1) runs county by county, and the Cass County row reads ice shield underlayment required Yes. The State Building Commissioner's memo explains what that column does: "there are specific counties in which it is always required (per Table R301.2(1))", and Cass is one of them. The provision the column switches on, as the memo reproduces it, is R905.1.2: "an ice barrier shall be installed for asphalt shingles, metal roof shingles, mineral-surfaced roll roofing, slate and slate-type shingles, wood shingles and wood shakes." The barrier must "extend from the lowest edges of all roof surfaces to a point not less than 24 inches (610 mm) inside the exterior wall line of the building", and on steep roofs the memo adds: "On roofs with slope equal to or greater than eight units vertical in 12 units horizontal (67-percent slope), the ice barrier shall also be applied not less than 36 inches (914 mm) measured along the roof slope from the eave edge of the building." The one exception it lists is detached accessory structures not containing conditioned floor area. The column differs from county to county across Indiana, so an ice-barrier assumption carried in from another county can be wrong in either direction.
City of Marion Building Department (City of Marion, Grant County, Indiana)
REQUIRED ON EVERY ROOF IN THE CITY, NEW OR REROOF, AND THE CITY HAS PUT THE RULE IN WRITING. The Building Department's sheet of required inspections, printed inside its residential permit application, reads: "ROOF: AFTER TEAR OFF AND A FINAL. ICE AND WATER SHIELD IS REQUIRED AND MUST BE INSPECTED." Asked in writing whether that sheet is current, the Department said it is (Written reply from the City of Marion Building Department, Sep 22, 2026): it is "given out with all of our permit applications", "our rules on this have not changed since 2020", and that "we do require ice and water shield as a separate jurisdiction from the county." WHERE IT GOES. The reply enclosed a written notice from the Office of the Building Commissioner headed "NOTICE OF LOCALE RULE", "RE: ROOFING STANDARDS", dated August 25, 2026 and signed by Building Commissioner Justin Dickerson. Its section on asphalt shingles and ice and water shield "shall serve as notice of local rule" and applies "to both new constructions as well as the application of new roofing to existing structures." Item 1 reads: "It shall be required that ice and water shield be applied along the gutter edges of all roofs and shall extend at least eighteen (18) inches past the interior wall." The notice is not posted online; the Department says it is available at its office, and it sent a copy by email on September 22, 2026 in reply to a written inquiry. THE ORDINANCE. The Department also pointed to General Ordinance No. 7-2018, Neighborhood Preservation, effective January 1, 2019, which the notice names as the City's minimum standards (Marion City Code Chapter 150). Its section 150.1.1(c) reads: "Ice and water shield flashing and all roofing material shall be sound, tight and not have defects that admit rain." That is a maintenance standard; the installation extent comes from the notice. The Chapter 150 now published on codelibrary.amlegal.com, rewritten by Ordinance 12-2019, was read on September 23, 2026 and its text does not contain that sentence. THE STATE TABLE. The Indiana Residential Code's Table R301.2(1), as amended by 675 IAC 14-4.4-5, prints No for Grant County in the ice shield column; the City's notice states that its roofing rules follow the 2020 Indiana Residential Code "with some stricter guidelines for buildings within city limits", and this is one of them. Outside the city limits Grant County's own record in this directory applies. MANUFACTURER'S INSTRUCTIONS. The notice adds that the Indiana Residential Code repeatedly requires roofing to be installed per the manufacturer's instructions, and that "These instructions supersede Indiana Residential Code's minimum standards, as well as the City of Marion's minimum standards"; so where a shingle maker calls for more membrane than 18 inches past the interior wall, follow the maker. WHAT THE DOCUMENTS DO NOT SAY. None of them states what happens at the tear-off inspection if the membrane is missing; the sheet says only that it "MUST BE INSPECTED". Budget it at the eaves on every Marion reroof.
City of Michigan City, Indiana - Building Permits & Inspection Department (City of Michigan City, Indiana)
REQUIRED IN LaPORTE COUNTY. This is a county-by-county answer in Indiana and it is the field most often got wrong here by carrying an answer up from a job further south. The state deletes the model climatic table and substitutes its own: 675 IAC 14-4.4-5 directs "Delete TABLE R301.2(1) and the corresponding footnotes and substitute to read as follows", and the substituted table runs one row per county. Row 46 is LaPorte, and it carries "Yes" in the column headed "Ice Shield Underlayment Required". Twenty-seven of Indiana's ninety-two counties carry "Yes" there and they are the northern tier; the other sixty-five carry "No". The rest of the LaPorte County row is the northern Indiana set: wind speed 115 mph, seismic design category A, ground snow 30 psf, foundation depth 36 inches, winter design temperature 1 degree F, weathering Severe. The whole Lake Michigan shore reads the same way - Lake and Porter Counties to the west and St. Joseph County to the east are all "Yes" - so a crew working the northern corridor is on the same answer throughout. Michigan City has no power to change it: IC 22-13-2-3(c) bars a city, town or county from an ordinance more stringent or detailed than the state rules. WHAT THE BARRIER HAS TO BE. The Indiana State Building Commissioner publishes the adopted Section R905.1.2 first-hand, on Indiana Department of Homeland Security letterhead, in the Ice/Water Shield and Metal Drip Edge guidance of February 25, 2020: "In areas where there has been a history of ice forming along the eaves causing a backup of water as designated in Table R301.2(1), an ice barrier shall be installed for asphalt shingles, metal roof shingles, mineral-surfaced roll roofing, slate and slate-type shingles, wood shingles and wood shakes. The ice barrier shall consist of not fewer than two layers of underlayment cemented together, or a self-adhering polymer-modified bitumen sheet shall be used in place of normal underlayment and extend from the lowest edges of all roof surfaces to a point not less than 24 inches (610 mm) inside the exterior wall line of the building. On roofs with slope equal to or greater than eight units vertical in 12 units horizontal (67-percent slope), the ice barrier shall also be applied not less than 36 inches (914 mm) measured along the roof slope from the eave edge of the building." The same section carries one exception: "Detached accessory structures not containing conditioned floor area." Note that 24 inches inside the exterior wall line is measured from the wall, not from the eave, so on a house with a deep overhang the barrier runs further up the slope than a 36 inch roll suggests.
City of Mishawaka, Indiana - Building Department (City of Mishawaka, Indiana)
REQUIRED IN ST. JOSEPH COUNTY, AND THIS IS THE INDIANA FIELD MOST OFTEN GOT WRONG BY ASSUMING A STATEWIDE ANSWER. Indiana deletes the model IRC Table R301.2(1) and substitutes its own table at 675 IAC 14-4.4-5 with a separate row for each of the 92 counties. Reading across the St. Joseph County row to the column headed "Ice Shield Underlayment Required", the entry is "Yes". Twenty-seven northern counties carry Yes and the other sixty-five carry No, so an answer brought over from an Indianapolis or Carmel job would be wrong here. Mishawaka lies wholly within St. Joseph County. The same row gives a 30 psf ground snow load, a 36-inch foundation depth and a 1 degree F winter design temperature. The Indiana State Building Commissioner has published what this means for a roof, on Indiana Department of Homeland Security letterhead, reproducing the code text in full: "R905.1.2 Ice barriers. In areas where there has been a history of ice forming along the eaves causing a backup of water as designated in Table R301.2(1), an ice barrier shall be installed for asphalt shingles, metal roof shingles, mineral-surfaced roll roofing, slate and slate-type shingles, wood shingles and wood shakes. The ice barrier shall consist of not fewer than two layers of underlayment cemented together, or a self-adhering polymer-modified bitumen sheet shall be used in place of normal underlayment and extend from the lowest edges of all roof surfaces to a point not less than 24 inches (610 mm) inside the exterior wall line of the building. On roofs with slope equal to or greater than eight units vertical in 12 units horizontal (67-percent slope), the ice barrier shall also be applied not less than 36 inches (914 mm) measured along the roof slope from the eave edge of the building. Exception: Detached accessory structures not containing conditioned floor area." The same memo draws the line between the two kinds of Indiana county: "there are specific counties in which it is always required (per Table R301.2(1)), and specific counties in which it is required only when the roofing manufacturer's written installation instructions require it (per Sections R903.1, R904.1 and R905.1)." St. Joseph is one of the always-required counties. Mishawaka adds nothing to this and could not: IC 22-13-2-3(c) bars a local ordinance more stringent or detailed than the state commission's rules.
City of Peru Building Department (City of Peru, Indiana)
REQUIRED IN MIAMI COUNTY BY THE STATE TABLE. The Indiana Residential Code's Table R301.2(1) runs county by county, and in the copy the State Building Commissioner's memo reproduces, the Miami County row reads Yes in the ice shield underlayment column. The memo explains what that means: "there are specific counties in which it is always required (per Table R301.2(1))", as distinct from counties where the membrane is required only when the manufacturer's written installation instructions call for it. Miami is one of the always counties. Peru writes nothing of its own on this: Chapter 152 contains no occurrence of ice or snow. So on a Peru shingle reroof the ice barrier is a code requirement, not a manufacturer or warranty option.
City of Plymouth Building Commissioner (City of Plymouth, Indiana)
REQUIRED IN MARSHALL COUNTY BY THE STATE TABLE. The Indiana Residential Code's Table R301.2(1), as substituted by 675 IAC 14-4.4-5, runs county by county, and the Marshall row marks ice shield underlayment required Yes. R905.1.2 then requires an ice barrier for asphalt shingles, metal roof shingles, mineral-surfaced roll roofing, slate and slate-type shingles, wood shingles and wood shakes in areas so designated. The State Building Commissioner's memo spells out the consequence: "there are specific counties in which it is always required (per Table R301.2(1))". Marshall is one of them. The code's own exception is for detached accessory structures not containing conditioned floor area. Plymouth has no ordinance touching this; Chapter 153 contains no ice or snow provision.
City of Portage Building Department (City of Portage, Indiana)
REQUIRED IN PORTAGE, BECAUSE PORTER COUNTY IS ON THE STATE'S ICE BARRIER LIST. Indiana replaces the model climatic table with its own county by county table: 675 IAC 14-4.4-5 directs "Delete TABLE R301.2(1) and the corresponding footnotes and substitute to read as follows", and the Porter County row carries Yes in the column headed "Ice Shield Underlayment Required". The State Building Commissioner's guidance of February 25, 2020 explains the split: "there are specific counties in which it is always required (per Table R301.2(1)), and specific counties in which it is required only when the roofing manufacturer's written installation instructions require it". Porter County is in the first group, so here the barrier is required by the table whatever the shingle wrapper says. WHAT THE BARRIER MUST BE, as that guidance reproduces the adopted section: "R905.1.2 Ice barriers. In areas where there has been a history of ice forming along the eaves causing a backup of water as designated in Table R301.2(1), an ice barrier shall be installed for asphalt shingles, metal roof shingles, mineral-surfaced roll roofing, slate and slate-type shingles, wood shingles and wood shakes. The ice barrier shall consist of not fewer than two layers of underlayment cemented together, or a self-adhering polymer-modified bitumen sheet shall be used in place of normal underlayment and extend from the lowest edges of all roof surfaces to a point not less than 24 inches (610 mm) inside the exterior wall line of the building." The same section adds a 36 inch measurement along the slope on roofs of eight in twelve or steeper, and exempts "Detached accessory structures not containing conditioned floor area." Portage writes nothing of its own on this: Chapter 14 contains no ice barrier or underlayment provision.
City of South Bend / St. Joseph County, Indiana - Building Department (City of South Bend, Indiana)
REQUIRED IN ST. JOSEPH COUNTY, AND THIS IS THE FIELD MOST OFTEN GOT WRONG IN INDIANA BY ASSUMING A STATEWIDE ANSWER. Indiana deletes the model IRC Table R301.2(1) and substitutes its own table at 675 IAC 14-4.4-5 with a separate row for each of the 92 counties, and the column "Ice Shield Underlayment Required" reads "Yes" for St. Joseph County. Twenty seven northern counties read Yes and the other sixty five read No, so an answer carried over from a job in Indianapolis or Carmel would be wrong here. South Bend sits entirely within St. Joseph County. The same row gives a 30 psf ground snow load and a 1 degree F winter design temperature, the northern Indiana figures. South Bend adds nothing to this and could not: IC 22-13-2-3(c) bars a local ordinance more stringent or detailed than the commission's rules. What the ice barrier must consist of and how far up the roof it must run are set by the base International Residential Code, which 675 IAC 14-4.4 does not amend on that point.
City of Valparaiso Department of Building and Code Enforcement (City of Valparaiso, Indiana)
REQUIRED, AND PORTER IS ONE OF THE COUNTIES THE STATE TABLE NAMES - WHICH MOST OF INDIANA IS NOT. The Indiana Residential Code's Table R301.2(1) runs county by county, and the Porter row reads: wind speed 115, seismic design category A, ground snow load 30, frost depth 36, winter design temperature 1 degree, decay slight to moderate, termite moderate to heavy, weathering severe, ice shield underlayment required Yes, air freezing index 2000, mean annual temperature 49.6 degrees. The ice shield column reads Yes. The provision it triggers is R905.1.2: the barrier must consist of not fewer than two layers of underlayment cemented together, or a self-adhering polymer-modified bitumen sheet, and must extend from the lowest edges of all roof surfaces to a point not less than 24 inches inside the exterior wall line. THE PRACTICAL WARNING. Tippecanoe and Vigo counties both read No in that same column. An Indiana roofer moving between counties cannot carry a practice either way, and this is a state determination reaching Valparaiso through the code it adopts, not a rule the City wrote.
City of Wabash Building Department (City of Wabash, Indiana)
REQUIRED IN WABASH COUNTY BY THE STATE'S OWN TABLE, AND THE CITY'S PERMIT FORM SAYS SO TOO. The Indiana Residential Code's Table R301.2(1), as amended by 675 IAC 14-4.4-5, runs county by county, and the Wabash row reads ice shield underlayment required Yes. That Yes switches on section R905.1.2, which the State Building Commissioner's 2020 memo reproduces: "an ice barrier shall be installed for asphalt shingles, metal roof shingles, mineral-surfaced roll roofing, slate and slate-type shingles, wood shingles and wood shakes", with an exception for "Detached accessory structures not containing conditioned floor area." The memo puts the effect plainly: "there are specific counties in which it is always required (per Table R301.2(1))". The City's own Improvement Location Permit application carries the rule under its roofing-material line: "Ice and water shield is required to be installed on all primary structure roof alterations and on accessory structure roof alterations if the structure is heated." It adds that the membrane must run from the eave's edge to a point 24 inches inside the exterior wall line, which is the state figure rather than a local addition; the barrier's construction and its steep-slope extension are set out in the memo.
City of Warsaw, Indiana - Code Enforcement and Building Department (City of Warsaw, Indiana)
REQUIRED IN KOSCIUSKO COUNTY, ALWAYS - THIS IS ONE OF THE TWENTY-SEVEN "YES" COUNTIES. Indiana deletes the model climatic table and substitutes its own: 675 IAC 14-4.4-5 directs "Delete TABLE R301.2(1) and the corresponding footnotes and substitute to read as follows", and the substituted table runs one row per county. Row 43 is Kosciusko, and it carries "Yes" in the column headed "Ice Shield Underlayment Required". Twenty-seven of Indiana's ninety-two counties carry "Yes" there and they are the northern tier; the other sixty-five carry "No". The rest of the Kosciusko row is the northern Indiana set - wind speed 115 mph, seismic design category A, ground snow 30 psf, foundation depth 36 inches, winter design temperature 1 degree F, weathering Severe, air freezing index 2000, mean annual temperature 49.0 degrees F. WHY THE DISTINCTION MATTERS ON A QUOTE: the State Building Commissioner explains that in a "No" county the barrier is required only where the shingle manufacturer's written installation instructions call for it, while in a "Yes" county the table itself requires it - "there are specific counties in which it is always required (per Table R301.2(1)), and specific counties in which it is required only when the roofing manufacturer's written installation instructions require it". Warsaw is in an always-required county, so it goes on every asphalt shingle re-roof regardless of what the shingle wrapper says. WHAT THE BARRIER HAS TO BE, from the version of the section actually in force, published first-hand by the Indiana State Building Commissioner on Indiana Department of Homeland Security letterhead in the Ice/Water Shield and Metal Drip Edge guidance of February 25, 2020: "In areas where there has been a history of ice forming along the eaves causing a backup of water as designated in Table R301.2(1), an ice barrier shall be installed for asphalt shingles, metal roof shingles, mineral-surfaced roll roofing, slate and slate-type shingles, wood shingles and wood shakes. The ice barrier shall consist of not fewer than two layers of underlayment cemented together, or a self-adhering polymer-modified bitumen sheet shall be used in place of normal underlayment and extend from the lowest edges of all roof surfaces to a point not less than 24 inches (610 mm) inside the exterior wall line of the building. On roofs with slope equal to or greater than eight units vertical in 12 units horizontal (67-percent slope), the ice barrier shall also be applied not less than 36 inches (914 mm) measured along the roof slope from the eave edge of the building." The section carries one exception: "Detached accessory structures not containing conditioned floor area." So a detached unheated garage in Warsaw is outside it, and a heated one is not. A lakeside cottage around Winona Lake or Center Lake that is heated is inside it.
Elkhart County Planning & Development - Building Division (Elkhart County, Indiana)
REQUIRED, AND ELKHART IS ONE OF THE COUNTIES THE STATE TABLE NAMES. This is a state determination reaching the County through its wholesale adoption of Article 14, not a rule Elkhart County wrote. The Indiana Residential Code's own Table R301.2(1), codified at 675 IAC 14-4.4-5, runs county by county, and the Elkhart row reads: "20 Elkhart 115 A 30 36 1 Slight to Moderate Moderate to Heavy Severe Yes 50.5", the columns being county, wind speed, seismic design category, ground snow load, foundation depth, winter design temperature, decay, termite, weathering, ice shield underlayment required, air freezing index and mean annual temperature. The ice shield column reads Yes. Elkhart County itself has enacted no separate ice-barrier provision and could not enact a weaker one. Note the distinction a roofer should carry: much of Indiana reads No in that column, so an ice barrier practice brought from another Indiana county is not transferable in either direction.
Kosciusko County Area Plan Commission (Kosciusko County, Indiana (unincorporated areas and participating towns))
REQUIRED ON EVERY SHINGLE RE-ROOF OF A CONDITIONED BUILDING - KOSCIUSKO IS ONE OF INDIANA'S "YES" COUNTIES. Indiana replaces the model climatic table with its own county-by-county Table R301.2(1) at 675 IAC 14-4.4-5, and the State Building Commissioner reprints it at the end of the February 25, 2020 guidance. Row 43 is Kosciusko, and it carries "Yes" in the column headed "Ice Shield Underlayment Required". The guidance explains what that column does: "there are specific counties in which it is always required (per Table R301.2(1)), and specific counties in which it is required only when the roofing manufacturer's written installation instructions require it (per Sections R903.1, R904.1 and R905.1)." Kosciusko is in the first group, so the barrier goes on whatever the shingle wrapper says. The guidance reproduces the adopted section: the barrier runs "to a point not less than 24 inches (610 mm) inside the exterior wall line of the building", and "On roofs with slope equal to or greater than eight units vertical in 12 units horizontal (67-percent slope), the ice barrier shall also be applied not less than 36 inches (914 mm) measured along the roof slope from the eave edge of the building." Its one exception is "Detached accessory structures not containing conditioned floor area." No county ordinance touches any of this, and the absence of a county permit on an ordinary re-roof does not remove it.
Lake County, Indiana - Plan Commission, Planning and Building Department (Lake County, Indiana)
Lake County is one of the 27 Indiana counties where the ice barrier is required outright. Indiana deletes the model IRC Table R301.2(1) and substitutes its own county by county table at 675 IAC 14-4.4-5, and the Lake County row carries "Yes" in the column headed "Ice Shield Underlayment Required". This is a per county answer and not a state one. Most Indiana counties, Marion (Indianapolis) and Hamilton (Carmel) among them, carry "No" in that column and get an ice barrier only where the shingle manufacturer's written installation instructions call for one. A roofer who works both ends of Indiana should not carry the central Indiana answer north.
LaPorte County Building Department (LaPorte County, Indiana)
REQUIRED IN LaPORTE COUNTY, AND THIS IS THE NORTHERN-INDIANA ANSWER. Indiana replaces the model climatic table with its own county-by-county table: 675 IAC 14-4.4-5 directs "Delete TABLE R301.2(1) and the corresponding footnotes and substitute to read as follows", and row 46 of the substituted table, LaPorte, reads Yes in the column headed Ice Shield Underlayment Required. Lake and Porter Counties to the west read Yes as well. WHAT THE BARRIER IS. The State Building Commissioner's guidance reproduces the adopted Section R905.1.2: "In areas where there has been a history of ice forming along the eaves causing a backup of water as designated in Table R301.2(1), an ice barrier shall be installed for asphalt shingles, metal roof shingles, mineral-surfaced roll roofing, slate and slate-type shingles, wood shingles and wood shakes." The same section carries the barrier from the lowest edge of the roof to a point at least 24 inches inside the exterior wall line, measured from the wall and not the eave, so a deep overhang pushes it further up the slope. The County writes nothing on the subject: Chapter 151 has no ice, snow-load or underlayment provision. The County's codified adoption names an earlier state residential rule, and the County has published no statement of which edition it enforces; this answer is the 2020 Indiana Residential Code's.
Porter County, Indiana - Building Department (Porter County, Indiana)
REQUIRED IN PORTER COUNTY - IT IS A COUNTY-BY-COUNTY ANSWER IN INDIANA, NOT A STATE ONE. Indiana deletes the model climatic table and substitutes its own: 675 IAC 14-4.4-5 directs "Delete TABLE R301.2(1) and the corresponding footnotes and substitute to read as follows", and the substituted table runs one row per county. Row 64 is Porter, and it carries "Yes" in the column headed "Ice Shield Underlayment Required". Twenty-seven of Indiana's ninety-two counties carry "Yes" there and they are the northern tier; the other sixty-five carry "No". The rest of the Porter County row is the northern Indiana set: wind speed 115 mph, seismic design category A, ground snow 30 psf, foundation depth 36 inches, winter design temperature 1 degree, decay Slight to Moderate, termite Moderate to Heavy, weathering Severe, air freezing index 2000 and mean annual temperature 49.6 degrees. Neighbouring Lake and LaPorte Counties read "Yes" as well, so the whole lakeshore corridor is consistent on this point. WHAT THE BARRIER HAS TO BE, from the version of the section actually in force. The Indiana State Building Commissioner publishes the adopted Section R905.1.2 first-hand, on Indiana Department of Homeland Security letterhead, in the Ice/Water Shield and Metal Drip Edge guidance of February 25, 2020: "In areas where there has been a history of ice forming along the eaves causing a backup of water as designated in Table R301.2(1), an ice barrier shall be installed for asphalt shingles, metal roof shingles, mineral-surfaced roll roofing, slate and slate-type shingles, wood shingles and wood shakes. The ice barrier shall consist of not fewer than two layers of underlayment cemented together, or a self-adhering polymer-modified bitumen sheet shall be used in place of normal underlayment and extend from the lowest edges of all roof surfaces to a point not less than 24 inches (610 mm) inside the exterior wall line of the building. On roofs with slope equal to or greater than eight units vertical in 12 units horizontal ( 67-percent slope), the ice barrier shall also be applied not less than 36 inches (914 mm) measured along the roof slope from the eave edge of the building." The section carries one exception: "Detached accessory structures not containing conditioned floor area." AND THE SAME GUIDANCE MAKES A POINT WORTH CARRYING ACROSS THE COUNTY LINE: "there are specific counties in which it is always required (per Table R301.2(1)), and specific counties in which it is required only when the roofing manufacturer's written installation instructions require it". Porter County is in the first group, so here the barrier is required by the table itself and does not depend on what the shingle manufacturer says - but a crew working a job further south is in the second group and has to read the wrapper.
St. Joseph County, Indiana - Building Department (St. Joseph County, Indiana)
REQUIRED IN ST. JOSEPH COUNTY - IT IS A COUNTY-BY-COUNTY ANSWER IN INDIANA, NOT A STATE ONE. Indiana deletes the model climatic table and substitutes its own: 675 IAC 14-4.4-5 directs "Delete TABLE R301.2(1) and the corresponding footnotes and substitute to read as follows", and the substituted table runs one row per county. Row 71 is St. Joseph, and it carries "Yes" in the column headed "Ice Shield Underlayment Required". Twenty-seven of Indiana's ninety-two counties carry "Yes" there and they are the northern tier; the other sixty-five carry "No". The rest of the St. Joseph County row is the northern Indiana set: wind speed 115 mph, seismic design category A, ground snow 30 psf, foundation depth 36 inches, winter design temperature 1 degree, decay Slight to Moderate, termite Moderate to Heavy, weathering Severe, and mean annual temperature 49.1 degrees. Neighbouring Elkhart, LaPorte, Marshall and Starke Counties all read "Yes" as well. WHAT THE BARRIER HAS TO BE, from the version of the section actually in force. The Indiana State Building Commissioner publishes the adopted Section R905.1.2 first-hand, on Indiana Department of Homeland Security letterhead, in the Ice/Water Shield and Metal Drip Edge guidance of February 25, 2020: "In areas where there has been a history of ice forming along the eaves causing a backup of water as designated in Table R301.2(1), an ice barrier shall be installed for asphalt shingles, metal roof shingles, mineral-surfaced roll roofing, slate and slate-type shingles, wood shingles and wood shakes. The ice barrier shall consist of not fewer than two layers of underlayment cemented together, or a self-adhering polymer-modified bitumen sheet shall be used in place of normal underlayment and extend from the lowest edges of all roof surfaces to a point not less than 24 inches (610 mm) inside the exterior wall line of the building. On roofs with slope equal to or greater than eight units vertical in 12 units horizontal ( 67-percent slope), the ice barrier shall also be applied not less than 36 inches (914 mm) measured along the roof slope from the eave edge of the building." The section carries one exception: "Detached accessory structures not containing conditioned floor area." AND THE SAME GUIDANCE MAKES A POINT WORTH CARRYING ACROSS THE COUNTY LINE: "there are specific counties in which it is always required (per Table R301.2(1)), and specific counties in which it is required only when the roofing manufacturer's written installation instructions require it". St. Joseph County is in the first group, so here the barrier is required by the table itself and does not depend on what the shingle manufacturer says.
Town of Chesterton Building Department (Town of Chesterton, Indiana)
REQUIRED, BECAUSE THE STATE TABLE NAMES PORTER COUNTY. Indiana replaces the model climatic table with its own county-by-county Table R301.2(1) at 675 IAC 14-4.4-5. Row 64, Porter, carries "Yes" in the column headed "Ice Shield Underlayment Required". Most of the state's counties read "No" in that column. WHAT THE BARRIER MUST BE, from the adopted section as the Indiana State Building Commissioner reproduces it: "an ice barrier shall be installed for asphalt shingles, metal roof shingles, mineral-surfaced roll roofing, slate and slate-type shingles, wood shingles and wood shakes." It must consist of "not fewer than two layers of underlayment cemented together, or a self-adhering polymer-modified bitumen sheet" and must "extend from the lowest edges of all roof surfaces to a point not less than 24 inches (610 mm) inside the exterior wall line of the building." On roofs of 8:12 slope and steeper it must also run not less than 36 inches along the slope from the eave edge. The section's one exception is "Detached accessory structures not containing conditioned floor area." The same guidance explains the county split: "there are specific counties in which it is always required (per Table R301.2(1)), and specific counties in which it is required only when the roofing manufacturer's written installation instructions require it". Chesterton is in the first group, so the barrier does not depend on the shingle wrapper here. A crew working further south is in the second group and must read it. The Town adds nothing on this point.
Town of Griffith, Indiana - Building Department (Town of Griffith, Indiana)
REQUIRED IN LAKE COUNTY - IT IS A COUNTY-BY-COUNTY ANSWER IN INDIANA, NOT A STATE ONE. Indiana deletes the model climatic table and substitutes its own: 675 IAC 14-4.4-5 directs "Delete TABLE R301.2(1) and the corresponding footnotes and substitute to read as follows", and the substituted table runs one row per county. Row 45 is Lake, and it carries "Yes" in the column headed "Ice Shield Underlayment Required". Twenty-seven of Indiana's ninety-two counties carry "Yes" there and they are the northern tier; the other sixty-five carry "No". The rest of the Lake County row is the northern Indiana set: wind speed 115 mph, seismic design category A, ground snow 30 psf, foundation depth 36 inches, winter design temperature 1 degree, decay Slight to Moderate, termite Moderate to Heavy, weathering Severe, air freezing index 2000 and mean annual temperature 49.0 degrees. Neighbouring Porter and LaPorte Counties read "Yes" as well, so the whole lakeshore corridor is consistent on this point. WHAT THE BARRIER HAS TO BE, from the version of the section actually in force. The Indiana State Building Commissioner publishes the adopted Section R905.1.2 first-hand, on Indiana Department of Homeland Security letterhead, in the Ice/Water Shield and Metal Drip Edge guidance of February 25, 2020: "In areas where there has been a history of ice forming along the eaves causing a backup of water as designated in Table R301.2(1), an ice barrier shall be installed for asphalt shingles, metal roof shingles, mineral-surfaced roll roofing, slate and slate-type shingles, wood shingles and wood shakes. The ice barrier shall consist of not fewer than two layers of underlayment cemented together, or a self-adhering polymer-modified bitumen sheet shall be used in place of normal underlayment and extend from the lowest edges of all roof surfaces to a point not less than 24 inches (610 mm) inside the exterior wall line of the building. On roofs with slope equal to or greater than eight units vertical in 12 units horizontal ( 67-percent slope), the ice barrier shall also be applied not less than 36 inches (914 mm) measured along the roof slope from the eave edge of the building." The section carries one exception: "Detached accessory structures not containing conditioned floor area." AND THE SAME GUIDANCE MAKES A POINT WORTH CARRYING ACROSS THE COUNTY LINE: "there are specific counties in which it is always required (per Table R301.2(1)), and specific counties in which it is required only when the roofing manufacturer's written installation instructions require it". Lake County is in the first group, so in Griffith the barrier is required by the table itself and does not depend on what the shingle manufacturer says.
Town of Highland, Indiana - Building and Inspection Department (Town of Highland, Indiana)
REQUIRED IN LAKE COUNTY - IT IS A COUNTY-BY-COUNTY ANSWER IN INDIANA, NOT A STATE ONE. Indiana deletes the model climatic table and substitutes its own: 675 IAC 14-4.4-5 directs "Delete TABLE R301.2(1) and the corresponding footnotes and substitute to read as follows", and the substituted table runs one row per county. Row 45 is Lake, and it carries "Yes" in the column headed "Ice Shield Underlayment Required". Twenty-seven of Indiana's ninety-two counties carry "Yes" there and they are the northern tier; the other sixty-five carry "No". The rest of the Lake County row is the northern Indiana set: wind speed 115 mph, seismic design category A, ground snow 30 psf, foundation depth 36 inches, winter design temperature 1 degree, decay Slight to Moderate, termite Moderate to Heavy, weathering Severe, air freezing index 2000 and mean annual temperature 49.0 degrees. Neighbouring Porter and LaPorte Counties read "Yes" as well, so the whole lakeshore corridor is consistent on this point. WHAT THE BARRIER HAS TO BE, from the version of the section actually in force. The Indiana State Building Commissioner publishes the adopted Section R905.1.2 first-hand, on Indiana Department of Homeland Security letterhead, in the Ice/Water Shield and Metal Drip Edge guidance of February 25, 2020: "In areas where there has been a history of ice forming along the eaves causing a backup of water as designated in Table R301.2(1), an ice barrier shall be installed for asphalt shingles, metal roof shingles, mineral-surfaced roll roofing, slate and slate-type shingles, wood shingles and wood shakes.

On roofs with slope equal to or greater than eight units vertical in 12 units horizontal ( 67-percent slope), the ice barrier shall also be applied not less than 36 inches (914 mm) measured along the roof slope from the eave edge of the building."

AND THE SAME GUIDANCE MAKES A POINT WORTH CARRYING ACROSS THE COUNTY LINE: "there are specific counties in which it is always required (per Table R301.2(1)), and specific counties in which it is required only when the roofing manufacturer's written installation instructions require it". Lake County is in the first group, so in Highland the barrier is required by the table itself and does not depend on what the shingle manufacturer says. Do not take the answer from the Town Code's own list of adopted codes, which names the superseded CABO dwelling code; the requirement in force comes from the current state rule and its substituted table.
Town of Merrillville, Indiana - Planning and Building Department (Town of Merrillville, Indiana)
REQUIRED IN LAKE COUNTY - IT IS A COUNTY-BY-COUNTY ANSWER IN INDIANA, NOT A STATE ONE. Indiana deletes the model climatic table and substitutes its own: 675 IAC 14-4.4-5 directs "Delete TABLE R301.2(1) and the corresponding footnotes and substitute to read as follows", and the substituted table runs one row per county. Row 45 is Lake, and it carries "Yes" in the column headed "Ice Shield Underlayment Required". Twenty-seven of Indiana's ninety-two counties carry "Yes" there and they are the northern tier; the other sixty-five carry "No". The rest of the Lake County row is the northern Indiana set: wind speed 115 mph, seismic design category A, ground snow 30 psf, foundation depth 36 inches, winter design temperature 1 degree, decay Slight to Moderate, termite Moderate to Heavy, weathering Severe, air freezing index 2000 and mean annual temperature 49.0 degrees. Neighbouring Porter and LaPorte Counties read "Yes" as well, so the whole lakeshore corridor is consistent on this point. WHAT THE BARRIER HAS TO BE, from the version of the section actually in force. The Indiana State Building Commissioner publishes the adopted Section R905.1.2 first-hand, on Indiana Department of Homeland Security letterhead, in the Ice/Water Shield and Metal Drip Edge guidance of February 25, 2020: "In areas where there has been a history of ice forming along the eaves causing a backup of water as designated in Table R301.2(1), an ice barrier shall be installed for asphalt shingles, metal roof shingles, mineral-surfaced roll roofing, slate and slate-type shingles, wood shingles and wood shakes. The ice barrier shall consist of not fewer than two layers of underlayment cemented together, or a self-adhering polymer-modified bitumen sheet shall be used in place of normal underlayment and extend from the lowest edges of all roof surfaces to a point not less than 24 inches (610 mm) inside the exterior wall line of the building. On roofs with slope equal to or greater than eight units vertical in 12 units horizontal ( 67-percent slope), the ice barrier shall also be applied not less than 36 inches (914 mm) measured along the roof slope from the eave edge of the building." The section carries one exception: "Detached accessory structures not containing conditioned floor area." AND THE SAME GUIDANCE MAKES A POINT WORTH CARRYING ACROSS THE COUNTY LINE: "there are specific counties in which it is always required (per Table R301.2(1)), and specific counties in which it is required only when the roofing manufacturer's written installation instructions require it". Lake County is in the first group, so in Merrillville the barrier is required by the table itself and does not depend on what the shingle manufacturer says - but a crew working a job an hour south is in the second group and has to read the wrapper.
Town of Munster, Indiana - Community Development Department (Town of Munster, Indiana)
REQUIRED IN LAKE COUNTY - IT IS A COUNTY-BY-COUNTY ANSWER IN INDIANA, NOT A STATE ONE. Indiana deletes the model climatic table and substitutes its own: 675 IAC 14-4.4-5 directs "Delete TABLE R301.2(1) and the corresponding footnotes and substitute to read as follows", and the substituted table runs one row per county. Row 45 is Lake, and it carries "Yes" in the column headed "Ice Shield Underlayment Required". Twenty-seven of Indiana's ninety-two counties carry "Yes" there and they are the northern tier; the other sixty-five carry "No". The rest of the Lake County row is the northern Indiana set: wind speed 115 mph, seismic design category A, ground snow 30 psf, foundation depth 36 inches, winter design temperature 1 degree, decay Slight to Moderate, termite Moderate to Heavy, weathering Severe, air freezing index 2000 and mean annual temperature 49.0 degrees. Neighbouring Porter and LaPorte Counties read "Yes" as well, so the whole lakeshore corridor is consistent on this point. WHAT THE BARRIER HAS TO BE, from the version of the section actually in force. The Indiana State Building Commissioner publishes the adopted Section R905.1.2 first-hand, on Indiana Department of Homeland Security letterhead, in the Ice/Water Shield and Metal Drip Edge guidance of February 25, 2020: "In areas where there has been a history of ice forming along the eaves causing a backup of water as designated in Table R301.2(1), an ice barrier shall be installed for asphalt shingles, metal roof shingles, mineral-surfaced roll roofing, slate and slate-type shingles, wood shingles and wood shakes. The ice barrier shall consist of not fewer than two layers of underlayment cemented together, or a self-adhering polymer-modified bitumen sheet shall be used in place of normal underlayment and extend from the lowest edges of all roof surfaces to a point not less than 24 inches (610 mm) inside the exterior wall line of the building. On roofs with slope equal to or greater than eight units vertical in 12 units horizontal ( 67-percent slope), the ice barrier shall also be applied not less than 36 inches (914 mm) measured along the roof slope from the eave edge of the building." The section carries one exception: "Detached accessory structures not containing conditioned floor area." AND THE SAME GUIDANCE MAKES A POINT WORTH CARRYING ACROSS THE COUNTY LINE: "there are specific counties in which it is always required (per Table R301.2(1)), and specific counties in which it is required only when the roofing manufacturer's written installation instructions require it". Lake County is in the first group, so in Munster the barrier is required by the table itself and does not depend on what the shingle manufacturer says. Do not take the answer from Munster's own codified list of adopted codes, which names the 2003 International Residential Code; the barrier requirement in force comes from the current state rule and its substituted table.
Town of Schererville, Indiana - Planning and Building Department (Town of Schererville, Indiana)
REQUIRED IN LAKE COUNTY - AND DO NOT WORK FROM THE EXCERPT ON THE TOWN'S OWN CODES PAGE, WHICH IS A SUPERSEDED SECTION. The requirement itself is not in doubt. Indiana deletes the model climatic table and substitutes its own: 675 IAC 14-4.4-5 directs "Delete TABLE R301.2(1) and the corresponding footnotes and substitute to read as follows", and the substituted table runs one row per county. Row 45 is Lake, and it carries "Yes" in the column headed "Ice Shield Underlayment Required". Twenty-seven of Indiana's ninety-two counties carry "Yes" there and they are the northern tier; the other sixty-five carry "No". The rest of the Lake County row is the northern Indiana set: wind speed 115 mph, seismic design category A, ground snow 30 psf, foundation depth 36 inches, winter design temperature 1 degree F, weathering Severe. Neighbouring Porter and LaPorte Counties read "Yes" as well, so the whole lakeshore corridor is consistent on this point. WHAT THE BARRIER HAS TO BE, from the version of the section actually in force. The Indiana State Building Commissioner publishes the adopted Section R905.1.2 first-hand, on Indiana Department of Homeland Security letterhead, in the Ice/Water Shield and Metal Drip Edge guidance of February 25, 2020: "In areas where there has been a history of ice forming along the eaves causing a backup of water as designated in Table R301.2(1), an ice barrier shall be installed for asphalt shingles, metal roof shingles, mineral-surfaced roll roofing, slate and slate-type shingles, wood shingles and wood shakes. The ice barrier shall consist of not fewer than two layers of underlayment cemented together, or a self-adhering polymer-modified bitumen sheet shall be used in place of normal underlayment and extend from the lowest edges of all roof surfaces to a point not less than 24 inches (610 mm) inside the exterior wall line of the building. On roofs with slope equal to or greater than eight units vertical in 12 units horizontal (67-percent slope), the ice barrier shall also be applied not less than 36 inches (914 mm) measured along the roof slope from the eave edge of the building." The section carries one exception: "Detached accessory structures not containing conditioned floor area." THE DISCREPANCY A ROOFER SHOULD KNOW ABOUT. Schererville's own Town Codes page highlights an ice-protection provision under the heading "R905.2.7.1 Ice Protection", and the text it prints is the older form of the rule, keyed to "areas where the average daily temperature in January is 25°F (-4°C) or less". Under the 2020 Indiana Residential Code the ice barrier provision is Section R905.1.2, it is triggered by the substituted Table R301.2(1) rather than by a January temperature, and it adds the 36 inch measurement on roofs of 8 in 12 or steeper - which the Town's excerpt does not mention. Both point the same way in Lake County, since the table says Yes, but the steep-slope measurement is a real difference on a job. Build to the section in force and raise the excerpt with the department if it is quoted back at you.
Ice barrier required — Iowa (15)
City of Ames, Iowa - Inspections Division (City of Ames, Iowa)
Required under BOTH of the criteria sets Ames currently publishes, so this answer does not turn on the unsettled edition question. The codified set, Ames Municipal Code Sec. 5.201 amending IRC Table R301.2(1), states "Ice Shield Underlayment Required Yes"; the Inspections Division's "Local Design Criteria" table for the 2024 International Residential Code lists "Ice Shield Underlayment required: Yes" for the city.
City of Ankeny, Iowa - Development Services / Building Division (City of Ankeny, Iowa)
The City of Ankeny's own Table R301.2 insert (Municipal Code Sec. 184.20, applicable to the 2024 IRC as adopted at Chapter 184/Ordinance 2220) lists "Ice Barrier Underlayment Required: Yes." The city's Building Official's signed "Roof/re-roof compliance" letter separately cites IRC section "R905.2.7 Ice Barrier - required" as one of the code sections applicable to asphalt shingle roofing in Ankeny.
City of Cedar Rapids, Iowa - Building Services Department (City of Cedar Rapids, Iowa)
CITY-PUBLISHED requirement. The City of Cedar Rapids Building Services Department's roofing permit application / roofing standards require eave protection (ice dam protection) from the eave edge to a minimum of 24 inches inside the wall line - the standard IRC ice-barrier extent. The same city roofing standards specify 15-pound felt underlayment with laps of 2 inches for roof pitches of 4:12 and greater. Cedar Rapids is in a historically ice-dam-prone climate, and unlike Minnesota - where the ice barrier is imposed statewide by rule - this requirement here rests on Cedar Rapids' own adopted code and published roofing standards.
City of Davenport, Iowa - Building and Land Development (Building Division) (City of Davenport, Iowa)
CITY-SPECIFIC, sourced from Davenport's own local amendment table, not borrowed from any other jurisdiction. Davenport Municipal Code Sec. 15.12.052.A amends Table R301.2(1) of the adopted International Residential Code with Davenport-specific climatic and geographic design criteria, which include "Ice Barrier Underlayment Required" as "YES." See wind_design_criteria for the full table.
City of Des Moines, Iowa - Development Services Department, Permit and Development Center (City of Des Moines, Iowa)
Required both through the city's adopted code and through the city's own published guidance. The Table R301.2(1) climatic and geographic design criteria set out in Des Moines Municipal Code Sec. 26-300(g), as currently codified, list "Ice Shield Underlayment Required" as "Yes" for the city. The City of Des Moines Permit & Development Center handout "Residential Asphalt Shingle Requirements" separately spells out the ice-barrier specification for asphalt shingle roofs: an ice barrier of not fewer than two layers of underlayment cemented together, or a self-adhering polymer-modified bitumen sheet used in place of normal underlayment, extending from the lowest roof edges to a point not less than 24 inches inside the exterior wall line, with an additional 36-inch extension measured along the slope on roofs of 8:12 pitch or greater; detached accessory structures without conditioned floor area are excepted. The handout's edition label predates the city's 2024 code update (see adopted_code), so the precise IRC section number for this provision was not re-confirmed against the 2024 edition, but the underlying requirement is independently corroborated by the current Table R301.2(1) codification.
City of Fort Dodge, Iowa - Building Safety (City of Fort Dodge, Webster County, Iowa)
Required. Municipal Code section 14.04.040 completes Table R301.2(1) for the city and states at item (4)(f) "Ice shield underlayment: Yes." That entry is what switches the requirement on rather than merely describing the weather: the adopted International Residential Code conditions its ice barrier provisions on a history of local damage from ice damming as designated in Table R301.2(1), and Fort Dodge has made the designation. Where the barrier is required the code calls for it to extend from the lowest edges of all roof surfaces to a point at least 24 inches inside the exterior wall line of the building.
City of Iowa City, Iowa - Building Inspection Services (City of Iowa City, Iowa)
Required, and confirmed against the CURRENT adopted edition rather than the superseded 2009 ordinance. Iowa City Code 17-1-1 adopts the 2024 IRC; 17-1-3 modifies IRC Table R301.2(1) with local data, and the "Ice barrier underlayment required" column for Iowa City reads "Yes." That entry is what activates the model code's ice barrier provision at IRC R905.1.2 for this jurisdiction. Iowa City does NOT amend that provision or any other section of IRC Chapter 9 (Roof Assemblies) - its 17-1-3 amendments reach 24 IRC sections and none of them is in Chapter 9 - so the trigger is local but the substantive ice barrier requirement is the unamended 2024 IRC text, which is behind the ICC paywall and is not restated here. The supporting climatic context from the same amended table: weathering Severe, frost line depth 42 inches, mean annual temperature 50 degrees F, air freezing index 2000, and an outdoor winter design dry-bulb temperature of -6 degrees F in the accompanying Manual J block - an ice-dam climate on its face.
City of Marion, Iowa - Building Services (City of Marion, Linn County, Iowa)
Required. Requirement 4 of the City of Marion asphalt shingle roofing handout, headed Ice Dam Protection, provides that "an ice barrier meeting ASTM D 1970 shall consist of a self-adhering polymer modified bitumen sheet (ice guard) or 2 layers of underlayment cemented together," and that "ice dam protection shall extend from the eaves edge to a point 24 inches inside the exterior wall line of the building." Two details in that wording are worth carrying to the job. The city accepts an alternative to a membrane - two layers of underlayment cemented together satisfy the requirement as written. And the ice barrier is the starting course for the underlayment schedule that follows it: on roofs of 2:12 up to 4:12 the handout directs "apply ice barrier as stated above," then a 19 inch strip of underlayment, then 36 inch wide sheets overlapping successive sheets 19 inches, while on roofs of 4:12 or greater the ice barrier is followed by a single layer of underlayment applied shingle fashion with a 2 inch overlap and end laps offset by 6 feet.
City of Mason City, Iowa - Building Inspections Division (City of Mason City, Cerro Gordo County, Iowa)
Required. Mason City completed Table R301.2 of the 2024 International Residential Code for the city and entered "YES" in the ICE BARRIER UNDERLAYMENT REQUIRED column. That entry is the operative act rather than a description of the weather: note h to the table directs a jurisdiction to fill the column in with "YES" where there has been a history of local damage from the effects of ice damming, and the roof covering sections of the adopted code condition their ice barrier requirements on that designation. Where the barrier is required the code calls for it to extend from the lowest edges of all roof surfaces to a point at least 24 inches inside the exterior wall line of the building.
City of Sioux City, Iowa - Permit Center (City of Sioux City, Iowa)
The City of Sioux City's own Table R301.2 insert at Sioux City Municipal Code Sec. 20.04.040, item 13 (applicable to the 2024 IRC as adopted at Sec. 20.04.030), lists "Ice Shield Required: Yes" as a filled-in table cell for the jurisdiction.
City of Urbandale, Iowa - Community Development Department (City of Urbandale, Polk and Dallas Counties, Iowa)
Required, and read the second half of this note before relying on an exception. Urbandale Municipal Code section 150.03(B)(14) fills in Table R301.2(1) with "ice shield underlayment required: YES," which is the designation that switches the adopted code ice barrier provisions on. THE CITY OWN FOOTNOTE TO THAT TABLE ENTRY PROMISES AN ALTERNATIVE THAT THE CODE DOES NOT CONTAIN. The asterisk on "YES" carries the note "See amendment to IBS section 1507.2.8.2 and IRC section R905.2.7.1 regarding ice shield alternative" - IBS being an evident slip for IBC. The whole of Municipal Code Chapter 150 was read, covering sections 150.01 through 150.99 and including the complete residential amendment list at 150.03, which runs to thirty-four numbered items, and the building code amendment list at 150.04. There is no amendment to IBC section 1507.2.8.2 and none to IRC section R905.2.7.1 anywhere in the chapter; the only occurrences of either section number in the whole of Chapter 150 are inside the footnote that promises them. So on the enacted text the ice barrier requirement stands without the alternative, and a roofer intending to use an alternative assembly should get the building official position in writing first rather than rely on a cross-reference that leads nowhere.
City of Waterloo, Iowa - Building Permitting & Inspections (City of Waterloo, Iowa)
The City of Waterloo's own Ice Barrier Requirement handout quotes 2021 IRC R905.2.7 and R905.1.2 verbatim and its own Table 301.2 insert lists "Ice Barrier Underlayment Required: yes." The handout describes the barrier as required for asphalt shingles, metal roof shingles, mineral-surfaced roll roofing, slate and slate-type shingles, wood shingles and wood shakes, extending from the lowest roof edges to at least 24 inches inside the exterior wall line (36 inches on slopes of 8:12 or greater).
City of West Des Moines, Iowa - Development Services Department, Building Inspection Division (City of West Des Moines, Iowa)
The City of West Des Moines's own "One and Two Family Residential Plan Submittal Requirements & General Code Review Conditions" checklist instructs applicants to "Install ice and water membrane per building code where required on shingle roof systems," and separately states that "eave overhangs use may be exempted if energy efficient trusses are used." The checklist does not cite a specific code section number or state the underlayment's required extension distance up the roof slope; those figures would be set by the city's own climatic and geographic design-criteria table, which was not located as an independently published document on the city's own site.
Linn County, Iowa - Building Permits & Inspections (Linn County, Iowa)
Linn County's own Table R301.2(1) insert at Code of Ordinances Sec. 105-17, item (11) (applicable to the 2024 IRC as adopted at Sec. 105-16), lists "Ice Barrier Underlayment Required: YES" as a filled-in table cell for the jurisdiction.
Polk County, Iowa - Public Works, Building Services (Polk County, Iowa)
Polk County's own Table R301.2(1) insert at Construction Code Sec. 20.2.4, item 18 (applicable to the 2021 IRC as adopted for unincorporated Polk County), lists "Ice Shield Under Layment Required: Yes" as a filled-in table cell for the jurisdiction. The same table appears verbatim on the Building Services webpage.
Ice barrier required — Kansas (14)
City of De Soto - Building Inspection & Codes Enforcement (City of De Soto, Kansas)
De Soto City Code Section 4-204(y) amends Table R301.2(1) of the 2018 International Residential Code to include area-specific values, among them "Ice Barrier Underlayment Required – YES."
City of Edgerton - Community Development Department (City of Edgerton, Kansas)
Table R301.2(1) as amended by Edgerton Municipal Code Section 4-303 g) answers "Ice Barrier Required: Yes," so the ice barrier of IRC Section R905.1.2 applies to asphalt shingle roofs in the city.
City of Gardner - Building & Inspections (City of Gardner, Kansas)
Table R301.2(1) as amended by Gardner Municipal Code 15.50.020 K (Ordinance No. 2674) answers yes to ice barrier underlayment required. Item CC, amending Section R908.3, adds for every re-roof: "All re-roofing shall require two courses of ice and water." Its exception: "Where the existing roof assembly includes an ice barrier membrane that is adhered to the roof deck, the existing ice barrier membrane shall be permitted to remain in place and covered with an additional layer of ice barrier membrane in accordance with Section R905."
City of Leawood - Code Services / Building Permits (City of Leawood, Kansas)
The City's "Roofing Requirements" summary lists: "Ice Barrier Underlayment Required – at the lowest edges of all roof surfaces to a point at least 24 inches inside the exterior wall line of the building (sometimes 2 or 3 passes is required). Solid sheathing is required on that portion of the roof requiring the application of an ice barrier (wood shake and wood shingle roofs) – R905.2.7.1." The city's amended Table R301.2(1) sets "Ice Barrier Underlayment Required: Yes" city-wide, and the "Inspection Procedures" document confirms inspectors verify at the mid-phase roof inspection that "Ice and Water Shield is installed 24" inside the warm air wall at the eaves."
City of Lenexa - Building Codes Division (City of Lenexa, Kansas)
"Ice Barrier Underlayment (Section R905.1.2): Ice barrier shall consist of not fewer than two layers of underlayment cemented together, or a self-adhering polymer-modified bitumen sheet shall be used in place of normal underlayment and extend from the lowest edges of all roof surfaces to a point not less than 24 inches inside the exterior wall line of the building. On roofs with slope equal to or greater than eight units vertical in 12 units horizontal the ice barrier shall also be applied not less than 36 inches (914 mm) measured along the roof slope from the eave edge of the building. Note: Many manufacturers require ice barrier underlayment in valleys" (City of Lenexa, Residential Asphalt Roofing - Code Summary, rev. 11/2024).
City of Louisburg - Planning & Development Department (City of Louisburg, Kansas)
Louisburg City Code Section 4-202 amends Section R301.2 of the 2018 International Residential Code by inserting Table R301.2(1), Climatic and Geographic Design Criteria, whose ice shield underlayment column reads YES.
City of Olathe - Building Codes Division (City of Olathe, Kansas)
"Ice Barrier Underlayment – The ice barrier shall consist of not fewer than two layers of underlayment cemented together, or a self-adhering polymer-modified bitumen sheet shall be used in place of normal underlayment and extend from the lowest edges of all roof surfaces to a point not less than 24 inches inside the exterior wall line of the building. On roofs with slope equal or greater than eight units vertical in 12 units horizontal (67 percent slope), the ice barrier shall also be applied not less than 36 inches measured along the roof slope from the eave edge of the building – IRC R905.1.2" (City of Olathe, Residential Building Permits page, "Roofing" section).
City of Osawatomie - Building and Codes Department (City of Osawatomie, Kansas)
The city's Climatic and Geographic Design Criteria table in Section 4-202(c) of the Code of the City of Osawatomie, Kansas, amending the 2018 International Residential Code, states "Ice Barrier Underlayment Required Yes."
City of Ottawa - Community Development Department (City of Ottawa, Kansas)
Table R301.2 (1) as filled in by Ottawa Municipal Code Section 6-310 answers yes in the ice barrier column. The same section's amended R908.3 lets an existing adhered ice barrier stay: "Where the existing roof assembly includes an ice barrier membrane that is adhered to the roof deck, the existing ice barrier membrane shall be permitted to remain in place and covered with an additional layer of ice barrier membrane in accordance with Section R905."
City of Overland Park - Building Safety Division (City of Overland Park, Kansas)
"An ice barrier is required. Ice barriers shall be installed for asphalt shingles, metal roof shingles, mineral-surfaced roll roofing, slate and slate-type shingles, wood shingles and wood shakes. The ice barrier shall consist of not fewer than two layers of underlayment cemented together, or a self-adhering polymer-modified bitumen sheet shall be used in place of normal underlayment and extend from the lowest edges of all roof surfaces to a point not less than 24 inches (610 mm) inside the exterior wall line of the building. On roofs with a slope equal to or greater than eight units vertical in 12 units horizontal (67 percent slope), the ice barrier shall also be applied not less than 36 inches (914 mm) measured along the roof slope from the eave edge of the building" (City of Overland Park, Residential Building Permit Exceptions and Guidance, "Ice Barriers" section).
City of Paola - Building Inspection Department (City of Paola, Kansas)
Table R301.2(1), Climatic and Geographic Design Criteria, as amended by Section 4-202(3)(B) of the Code of the City of Paola (published in the code as a table image), lists Ice Barrier Underlayment Required: Yes. The city's Inspections page also states: "Ice and water shield is required by code."
Johnson County - Building Codes Division (Johnson County, Kansas (unincorporated))
Table R301.2(1) Climatic and Geographic Design Criteria, as amended by the Johnson County Code of Regulations for Buildings and Construction, 2018 Edition (Article 3, Section 5(d)), lists "Yes" in the Ice Barrier Underlayment Required column. The county's own "Requirements for Residential Roof Coverings" handout (effective July 1, 2020) reproduces the triggering condition at R905.1.2: "In areas where there has been a history of ice forming along the eaves causing a backup of water as designated in Table R301.2(1), an ice barrier shall be installed... and extend from the lowest edges of all roof surfaces to a point not less than 24 inches (610 mm) inside the exterior wall line of the building. On roofs with slope equal to or greater than eight units vertical in 12 units horizontal, the ice barrier shall also be applied not less than 36 inches (914 mm) measured along the roof slope from the eave edge."
Unified Government of Wyandotte County and Kansas City, Kansas - Building Inspection (City of Kansas City, Kansas)
The Unified Government of Wyandotte County/Kansas City, Kansas amends IRC Table R301.2(1) (Code Sec. 8-412, Article VII, One- and Two-Family Dwellings; Ord. No. O-97-22, 6-30-2022) to list "Ice Barrier Underlayment Required: Yes." Under the unamended 2018 IRC R905.1.2 baseline this extends from the eave edge to 24 in. inside the exterior wall line on all eaves. One consolidated code governs both the city and the county. Architect-verified directly on the current codification, 2026-07-18.
Unified Government of Wyandotte County and Kansas City, Kansas - Building Inspection (Wyandotte County, Kansas)
The Unified Government of Wyandotte County/Kansas City, Kansas amends IRC Table R301.2(1) (Code Sec. 8-412, Article VII, One- and Two-Family Dwellings; Ord. No. O-97-22, 6-30-2022) to list "Ice Barrier Underlayment Required: Yes."

Ice barrier required — Massachusetts (156)
City of Amesbury - Inspectional Services (City of Amesbury, Massachusetts)
Required statewide. Massachusetts replaces the code's climatic table with its own Table R301.2(1), and that table's ice barrier underlayment row reads "YES" for the whole state (780 CMR 51.00, Chapter 3). Section R905.1.2, which Massachusetts does not amend, then requires that "an ice barrier shall be installed for asphalt shingles, metal roof shingles, mineral-surfaced roll roofing, slate and slate-type shingles, wood shingles and wood shakes," made of "not fewer than two layers of underlayment cemented together, or a self-adhering polymer-modified bitumen sheet," and extending "from the lowest edges of all roof surfaces to a point not less than 24 inches (610 mm) inside the exterior wall line of the building." On roofs with a slope of 8 in 12 or steeper, "the ice barrier shall also be applied not less than 36 inches (914 mm) measured along the roof slope from the eave edge of the building." Detached accessory structures that contain no conditioned floor area are excepted. On a tear-off, an ice barrier membrane already adhered to the roof deck may stay in place and be covered with an additional layer of ice barrier membrane (R908.3, Exception). Massachusetts adds a rule of its own to Section R905.1: "Where there is a discrepancy between the requirements of this section and the manufacturer's printed instructions or code evaluation report, the manufacturer's printed instructions or code evaluation report shall govern." Everything above is Massachusetts state law, the same in every city and town.
City of Attleboro - Building Inspection (City of Attleboro, Massachusetts)
Required statewide. Massachusetts replaces the code's climatic table with its own Table R301.2(1), and that table's ice barrier underlayment row reads "YES" for the whole state (780 CMR 51.00, Chapter 3). Section R905.1.2, which Massachusetts does not amend, then requires that "an ice barrier shall be installed for asphalt shingles, metal roof shingles, mineral-surfaced roll roofing, slate and slate-type shingles, wood shingles and wood shakes," made of "not fewer than two layers of underlayment cemented together, or a self-adhering polymer-modified bitumen sheet," and extending "from the lowest edges of all roof surfaces to a point not less than 24 inches (610 mm) inside the exterior wall line of the building." On roofs with a slope of 8 in 12 or steeper, "the ice barrier shall also be applied not less than 36 inches (914 mm) measured along the roof slope from the eave edge of the building." Detached accessory structures that contain no conditioned floor area are excepted. On a tear-off, an ice barrier membrane already adhered to the roof deck may stay in place and be covered with an additional layer of ice barrier membrane (R908.3, Exception). Massachusetts adds a rule of its own to Section R905.1: "Where there is a discrepancy between the requirements of this section and the manufacturer's printed instructions or code evaluation report, the manufacturer's printed instructions or code evaluation report shall govern." Everything above is Massachusetts state law, the same in every city and town.
City of Beverly - Municipal Inspections / Building Department (City of Beverly, Massachusetts)
Required statewide. Massachusetts replaces the code's climatic table with its own Table R301.2(1), and that table's ice barrier underlayment row reads "YES" for the whole state (780 CMR 51.00, Chapter 3). Section R905.1.2, which Massachusetts does not amend, then requires that "an ice barrier shall be installed for asphalt shingles, metal roof shingles, mineral-surfaced roll roofing, slate and slate-type shingles, wood shingles and wood shakes," made of "not fewer than two layers of underlayment cemented together, or a self-adhering polymer-modified bitumen sheet," and extending "from the lowest edges of all roof surfaces to a point not less than 24 inches (610 mm) inside the exterior wall line of the building." On roofs with a slope of 8 in 12 or steeper, "the ice barrier shall also be applied not less than 36 inches (914 mm) measured along the roof slope from the eave edge of the building." Detached accessory structures that contain no conditioned floor area are excepted. On a tear-off, an ice barrier membrane already adhered to the roof deck may stay in place and be covered with an additional layer of ice barrier membrane (R908.3, Exception). Massachusetts adds a rule of its own to Section R905.1: "Where there is a discrepancy between the requirements of this section and the manufacturer's printed instructions or code evaluation report, the manufacturer's printed instructions or code evaluation report shall govern." Everything above is Massachusetts state law, the same in every city and town.
City of Boston - Inspectional Services Department (City of Boston, Massachusetts)
Required statewide.

The state footnote calls for Yes "for areas where the average daily temperature in January is 25 degrees Fahrenheit" or less, or where ice damming has caused damage. The base code then requires an ice barrier "for asphalt shingles, metal roof shingles, mineral-surfaced roll roofing, slate and slate-type shingles, wood shingles and wood shakes," running "from the lowest edges of all roof surfaces to a point not less than 24 inches (610 mm) inside the exterior wall line of the building" (R905.1.2). Detached accessory structures without conditioned floor area are exempt. On a tear-off, an existing ice barrier that is adhered to the deck may stay and be covered with an additional layer (R908.3, Exception). The Wexford County Building Department pages, fee schedule and information packet, and Wexford County Zoning Ordinance No. 5 (searched in full text), were read for a local rule and state nothing further on ice barrier.

Ice barrier required — Minnesota (56)
City of Andover, Minnesota - Building Department (City of Andover, Minnesota)
Required by the State Building Code across Minnesota. Minnesota Rules part 1309.0301, subpart 2 rewrites IRC Table R301.2(1), Climatic and Geographic Design Criteria, for the whole state, and its ICE BARRIER UNDERLAYMENT REQUIRED entry reads Yes. The Minnesota Department of Labor and Industry's guidance sheet describes the barrier: "an ice barrier that consists of at least two layers of underlayment cemented together or of a self-adhering polymer modified bitumen sheet, be used in lieu of normal underlayment and extend from the eave's edge to a point at least 24 inches inside the exterior wall line of the building," and adds "Ice barrier protection at eaves is required in Minnesota." Andover has no power to waive it (Minn. Stat. 326B.121, subd. 2(c)).
City of Anoka, Minnesota - Building Department Division (City of Anoka, Minnesota)
Required by the State Building Code across Minnesota. Minnesota Rules part 1309.0301, subpart 2 rewrites IRC Table R301.2(1), Climatic and Geographic Design Criteria, for the whole state, and its ICE BARRIER UNDERLAYMENT REQUIRED entry reads Yes. The Minnesota Department of Labor and Industry's guidance sheet describes the barrier: "an ice barrier that consists of at least two layers of underlayment cemented together or of a self-adhering polymer modified bitumen sheet, be used in lieu of normal underlayment and extend from the eave's edge to a point at least 24 inches inside the exterior wall line of the building," and adds "Ice barrier protection at eaves is required in Minnesota." Anoka has no power to waive it (Minn. Stat. 326B.121, subd. 2(c)).
City of Apple Valley, Minnesota - Building Inspections (City of Apple Valley, Minnesota)
Apple Valley states the requirement in its own words on its Roofing page: "Ice protection shall be installed on all roofs, including porches and attached garages. Ice protection is not required on unheated detached accessory structures. Protection shall be from the eave to a point twenty-four (24) inches inside the exterior wall line. The ice barrier shall consist of two layers of felt cemented together or a self-adhering polymer modified bitumen sheet." Note the exemption turns on an accessory structure being both DETACHED and UNHEATED, not on detachment alone. The City adds a documentation requirement: "Photos of the ice barrier are required on site at the scheduled final inspection," and separately asks that those photos be emailed to [email protected] with the address or permit number in the subject line. This is state-governed content rather than a city choice: Minnesota Rules part 1309.0301, subpart 2 amends IRC Table R301.2(1) to read "ICE BARRIER UNDERLAYMENT REQUIRED[h] ... Yes" for the whole state. Apple Valley also requires underlayment beneath the shingles in addition to the ice barrier: "underlayment is required under all asphalt shingles and shall consist of a minimum of one layer of #15 felt or other approved products."
City of Arden Hills, Minnesota - Building & Permits (City of Arden Hills, Minnesota)
Required by the State Building Code across Minnesota. Minnesota Rules part 1309.0301, subpart 2 rewrites IRC Table R301.2(1), Climatic and Geographic Design Criteria, for the whole state, and its ICE BARRIER UNDERLAYMENT REQUIRED entry reads Yes. The Minnesota Department of Labor and Industry's guidance sheet describes the barrier: "an ice barrier that consists of at least two layers of underlayment cemented together or of a self-adhering polymer modified bitumen sheet, be used in lieu of normal underlayment and extend from the eave's edge to a point at least 24 inches inside the exterior wall line of the building," and adds "Ice barrier protection at eaves is required in Minnesota." Arden Hills has no power to waive it (Minn. Stat. 326B.121, subd. 2(c)).
City of Blaine, Minnesota - Building Inspections Division (City of Blaine, Minnesota)
Blaine's own "Residential Roofing" reference handout states directly: "An ice and water barrier is required on all roofs, except for detached accessory buildings (garages). The barrier may consist of at least two layers of underlayment cemented together or a self-adhering polymer-modified bitumen sheet... The ice and water barrier must extend from the edge of the eaves to a point 24 inches inside the exterior wall line of the building. Ice and water barriers are required full-length in valleys." It further clarifies: "Ice and water protection is required on all attached garages. Exception: Detached accessory structures that contain no conditioned floor area," and "A maximum of two layers of ice and water barrier is permitted." This matches Minnesota Rules part 1309.0301, subpart 2, which amends IRC Table R301.2(1) to pre-fill "ICE BARRIER UNDERLAYMENT REQUIRED... Yes" statewide -- Blaine has no authority to opt out (Minn. Stat. § 326B.121, subd. 2(c)).
City of Bloomington, Minnesota - Building and Inspections Division (City of Bloomington, Minnesota)
STATE-GOVERNED, NOT CITY-SET -- applies identically in Bloomington as everywhere else in Minnesota. Minnesota Rules part 1309.0301, subpart 2 amends IRC Table R301.2(1) ("Climatic and Geographic Design Criteria") to pre-fill "ICE BARRIER UNDERLAYMENT REQUIRED[h] ... Yes" for the entire state. Corroborated by a Minnesota DLI consumer guidance sheet ("Asphalt Shingle Roofing and the 2020 Minnesota Residential Code," Construction Codes and Licensing Division): "Ice barrier protection at eaves is required in Minnesota," extending "from the eave's edge to a point at least 24 inches inside the exterior wall line of the building." Bloomington has no authority to opt out of this (Minn. Stat. § 326B.121, subd. 2(c)). Garages: Bloomington's own FAQ adds a garage-specific answer: "Is an ice barrier required for roofing or reroofing a garage? An ice barrier is required for all attached garages and for all detached heated garages" -- implying detached unheated garages are exempt. Because ice-barrier applicability is state-governed code content that cities cannot vary, confirm the treatment of a detached unheated garage with the Building and Inspections Division before bidding it either way.
City of Brooklyn Park, Minnesota - Building Inspections Division (City of Brooklyn Park, Minnesota)
STATE-GOVERNED, and independently restated by Brooklyn Park's own published guidance. Minnesota Rules part 1309.0301, subpart 2 amends IRC Table R301.2(1) to pre-fill "ICE BARRIER UNDERLAYMENT REQUIRED[h] ... Yes" for the entire state. Brooklyn Park's own Residential Reroofing guide, under "ICE BARRIER MEMBRANE UNDERLAYMENTS," states verbatim: "An ice barrier that consists of at least two layers of underlayment cemented together or of a self-adhering polymer modified bitumen sheet, shall be used in lieu of normal underlayment, and extend from the eave edge to a point at least 24 inches horizontally inside the exterior wall line of the building. (R905.1.2)" It further addresses reroofing over an existing adhered ice barrier: "Where the existing roof assembly includes an ice barrier membrane that is adhered to the roof deck, the existing ice barrier membrane shall be permitted to remain in place and covered with an additional layer of ice barrier membrane. (R908.3)"

Locally, the City of Burnsville's own "Re-Roofing Requirements" handout states, under a heading "Ice Barrier Required!!!": "The Minnesota building code requires that an approved ice barrier underlayment be installed from your roofs edge to a point at least 24 inches past the exterior wall line. This applies to all portions of your roof, including attached heated or un-heated garages, covered porches, bays, fireplace enclosures and similar areas" -- and requires photographic proof of the ice barrier before final inspection.
City of Champlin, Minnesota - Building Inspections Division (City of Champlin, Minnesota)

City of Coon Rapids, Minnesota - Building Inspections Division (City of Coon Rapids, Minnesota)
The City of Coon Rapids' own "Residential Roofing" handout states, under "ICE BARRIERS R905.1.2," "All dwellings, structures attached to dwellings, and all conditioned (heated and/or cooled) structures, require ice barrier. The ice barrier shall consist of not fewer than two layers of underlayment cemented together, or a self-adhering polymer-modified bitumen sheet shall be used in place of normal underlayment and extend from the lowest edges of all roof surfaces to a point not less than 24 inches inside the exterior wall line of the building. On roofs with slope equal to or greater than 8:12, the ice barrier shall also be applied not less than 36 inches measured along the roof slope from the eave edge of the building.

City of Duluth, Minnesota - Construction Services & Inspections (City of Duluth, Minnesota)
Minn. R. 1309.0301, subp. 2, which amends IRC Table R301.2(1) (Climatic and Geographic Design Criteria) statewide, lists "Ice Barrier Underlayment Required" as "Yes," per footnote h, "in accordance with Sections R905.1.2, R905.2.7, R905.4.3.1, R905.5.3.1, R905.6.3.1, R905.7.3.1, and R905.8.3.1, where there has been a history of local damage from the effects of ice damming."

City of East Bethel, Minnesota - Building Inspections Division (City of East Bethel, Minnesota)
Required by the State Building Code across Minnesota.

Minnesota Rules part 1309.0301, subpart 2 amends IRC Table R301.2(1) ("Climatic and Geographic Design Criteria") to pre-fill "ICE BARRIER UNDERLAYMENT REQUIRED[h] ... Yes" for the entire state. The Minnesota Department of Labor and Industry's guidance sheet, "Asphalt Shingle Roofing and the 2020 Minnesota Residential Code," describes what satisfies it: an ice barrier "may be at least two layers of underlayment cemented together or a self-adhering polymer modified bitumen sheet," extending from the eave edge to a point at least 24 inches inside the exterior wall line of the building. Eden Prairie has no authority to opt out (Minn. Stat. 326B.121, subd. 1 makes the State Building Code the standard that applies statewide and provides that it supersedes the building code of any municipality, and subd. 2(c) bars a municipality from requiring building code provisions regulating components or systems of a structure that differ from the State Building Code). Garage and detached-accessory-structure applicability is worded differently by different Minnesota cities — Apple Valley exempts "unheated detached accessory structures" while Maplewood and Minnetonka exempt detached accessory buildings with no heated qualifier — so confirm that specific case with the building department rather than assuming a blanket detached-garage exemption.
City of Edina, Minnesota - Building Inspections Division (City of Edina, Minnesota)

The Minnesota Department of Labor and Industry's guidance sheet, "Asphalt Shingle Roofing and the 2020 Minnesota Residential Code," describes what satisfies it: an ice barrier "may be at least two layers of underlayment cemented together or a self-adhering polymer modified bitumen sheet," extending from the eave edge to a point at least 24 inches inside the exterior wall line of the building. Mankato has no authority to opt out (Minn. Stat. 326B.121, subd. 1 makes the State Building Code the standard that applies statewide and provides that it supersedes the building code of any municipality, and subd. 2(c) bars a municipality from requiring building code provisions regulating components or systems of a structure that differ from the State Building Code). Garage and detached-accessory-structure applicability is worded differently by different Minnesota cities — Apple Valley exempts "unheated detached accessory structures" while Maplewood and Minnetonka exempt detached accessory buildings with no heated qualifier — so confirm that specific case with the building department rather than assuming a blanket detached-garage exemption.
City of Maple Grove, Minnesota - Building Inspection Services (City of Maple Grove, Minnesota)
STATE-GOVERNED, NOT CITY-SET -- applies identically in Maple Grove as everywhere else in Minnesota. Minnesota Rules part 1309.0301, subpart 2 amends IRC Table R301.2(1) ("Climatic and Geographic Design Criteria") to pre-fill "ICE BARRIER UNDERLAYMENT REQUIRED[h] ... Yes" for the entire state -- footnote h ties this to IRC Sections R905.1.2 etc. "where there has been a history of local damage from the effects of ice damming," a determination Minnesota has made statewide by rule. Corroborated by a Minnesota DLI consumer guidance sheet: "Ice barrier protection at eaves is required in Minnesota," extending "from the eave's edge to a point at least 24 inches inside the exterior wall line of the building." Maple Grove has no authority to opt out of this (Minn. Stat. § 326B.121, subd. 2(c)). The literal installation-extent text of R905.1.2 itself, which Minnesota does not amend, could not be obtained verbatim (ICC paywall); the DLI sheet's restated figures are cited instead of the raw code section for that reason. On garages: Maple Grove's own official roofing handout ("Roofing," Building Department, Rev 4/7/2021, maplegrovemn.gov) states the exception as: "An ice and water barrier is required on all roofs except for detached accessory buildings (garages)" -- with no heated/conditioned qualifier at all. This is broader than the framing used by other Minnesota cities: Bloomington, MN's FAQ requires it "for all attached garages and for all detached HEATED garages" (i.e. only unheated detached garages are exempt), and an older Plymouth, MN handout ties the exemption to structures with "no conditioned floor areas" -- both narrower than Maple Grove's blanket "garages" wording. Because ice-barrier applicability is state-governed code content that no city can vary, Maple Grove's own handout may be overstating the exemption relative to the actual state rule (which appears to hinge on conditioned/heated status, not simply detached-vs-attached) -- a roofer relying on Maple Grove's literal wording for a detached, HEATED garage could be under-installing required ice barrier. Check the current R905.1.2 text before relying on the handout's wording for a heated detached garage.
City of Maplewood, Minnesota - Building Inspections (City of Maplewood, Minnesota)
Maplewood's roofing handout states: "An ice and water barrier is required on all roofs except for detached accessory buildings (garages). The barrier may be at least two layers of underlayment cemented together or a self-adhering polymer modified bitumen sheet... The ice and water barrier must extend from the edge of the eaves to a point at least 24 inches inside the exterior wall line of the building. Ice and water barriers are not required along the rakes or in valleys." This is state-governed content rather than a city choice: Minnesota Rules part 1309.0301, subpart 2 amends IRC Table R301.2(1) to read "ICE BARRIER UNDERLAYMENT REQUIRED[h] ... Yes" for the whole state, so the requirement survives the handout's 2015 revision date. WATCH THE GARAGE WORDING. Maplewood's exemption is written for "detached accessory buildings (garages)" with no heated or conditioned qualifier, whereas Apple Valley, Minnesota words the same exemption as applying to "unheated detached accessory structures" and Bloomington, Minnesota frames it around heated detached garages. Because applicability here is state code content rather than a municipal choice, confirm garage-specific applicability with the Building Department at 651-249-2300 rather than relying on a blanket detached-garage exemption.
City of Minneapolis, Minnesota - Community Planning & Economic Development, Development Services (Building Inspections) (City of Minneapolis, Minnesota)
STATE-GOVERNED, NOT CITY-SET -- applies identically in Minneapolis as everywhere else in Minnesota. Minnesota Rules part 1309.0301, subpart 2 amends IRC Table R301.2(1) ("Climatic and Geographic Design Criteria") to pre-fill "ICE BARRIER UNDERLAYMENT REQUIRED[h] ... Yes" for the entire state -- footnote h ties this to IRC Sections R905.1.2 etc. "where there has been a history of local damage from the effects of ice damming," a determination Minnesota has made statewide by rule rather than leaving to municipal option. Minneapolis has no authority to opt out of this (Minn. Stat. § 326B.121, subd. 2(c)). The literal installation-extent text of R905.1.2 itself is unamended bare 2018 IRC text that could not be obtained verbatim (ICC paywall) and is therefore not restated here.
City of Minnetonka, Minnesota - Building Inspections Division (City of Minnetonka, Minnesota)
Minnetonka states it in its own words: "An ice and water barrier is required on all roofs except for detached accessory buildings. The barrier may be at least two layers of underlayment cemented together or a self-adhering polymer modified bitumen sheet." Note the City's exemption is written for detached accessory buildings with no heated or conditioned qualifier, where Apple Valley, Minnesota words the same exemption as applying to "unheated detached accessory structures." The requirement itself is state-governed: Minnesota Rules part 1309.0301, subpart 2 amends IRC Table R301.2(1) to read "ICE BARRIER UNDERLAYMENT REQUIRED[h] ... Yes" for the whole state. The barrier is also what the City's single inspection checks — see the mid-roof inspection field.
City of Moorhead, Minnesota - Building Inspections (City of Moorhead, Minnesota)
STATE-GOVERNED, NOT CITY-SET — the requirement applies identically in Moorhead as everywhere else in Minnesota. Minnesota Rules part 1309.0301, subpart 2 amends IRC Table R301.2(1) ("Climatic and Geographic Design Criteria") to pre-fill "ICE BARRIER UNDERLAYMENT REQUIRED[h] ... Yes" for the entire state. The Minnesota Department of Labor and Industry's guidance sheet, "Asphalt Shingle Roofing and the 2020 Minnesota Residential Code," describes what satisfies it: an ice barrier "may be at least two layers of underlayment cemented together or a self-adhering polymer modified bitumen sheet," extending from the eave edge to a point at least 24 inches inside the exterior wall line of the building. Moorhead has no authority to opt out (Minn. Stat. 326B.121, subd. 1 makes the State Building Code the standard that applies statewide and provides that it supersedes the building code of any municipality, and subd. 2(c) bars a municipality from requiring building code provisions regulating components or systems of a structure that differ from the State Building Code). Garage and detached-accessory-structure applicability is worded differently by different Minnesota cities — Apple Valley exempts "unheated detached accessory structures" while Maplewood and Minnetonka exempt detached accessory buildings with no heated qualifier — so confirm that specific case with the building department rather than assuming a blanket detached-garage exemption.
City of Mounds View, Minnesota - Building Inspections & Permits (City of Mounds View, Minnesota)
Required by the State Building Code across Minnesota. Minnesota Rules part 1309.0301, subpart 2 rewrites IRC Table R301.2(1), Climatic and Geographic Design Criteria, for the whole state, and its ICE BARRIER UNDERLAYMENT REQUIRED entry reads Yes. The Minnesota Department of Labor and Industry's guidance sheet describes the barrier: "an ice barrier that consists of at least two layers of underlayment cemented together or of a self-adhering polymer modified bitumen sheet, be used in lieu of normal underlayment and extend from the eave's edge to a point at least 24 inches inside the exterior wall line of the building," and adds "Ice barrier protection at eaves is required in Minnesota." Mounds View has no power to waive it (Minn. Stat. 326B.121, subd. 2(c)).
City of New Hope, Minnesota - Inspections Division (City of New Hope, Minnesota)
Required by the State Building Code across Minnesota. Minnesota Rules part 1309.0301, subpart 2 rewrites IRC Table R301.2(1), Climatic and Geographic Design Criteria, for the whole state, and its ICE BARRIER UNDERLAYMENT REQUIRED entry reads Yes. The Minnesota Department of Labor and Industry's guidance sheet describes the barrier: "an ice barrier that consists of at least two layers of underlayment cemented together or of a self-adhering polymer modified bitumen sheet, be used in lieu of normal underlayment and extend from the eave's edge to a point at least 24 inches inside the exterior wall line of the building," and adds "Ice barrier protection at eaves is required in Minnesota." New Hope has no power to waive it (Minn. Stat. 326B.121, subd. 2(c)).
City of North St. Paul, Minnesota - Community Development (City of North St. Paul, Minnesota)
Required by the State Building Code across Minnesota. Minnesota Rules part 1309.0301, subpart 2 rewrites IRC Table R301.2(1), Climatic and Geographic Design Criteria, for the whole state, and its ICE BARRIER UNDERLAYMENT REQUIRED entry reads Yes. The Minnesota Department of Labor and Industry's guidance sheet describes the barrier: "an ice barrier that consists of at least two layers of underlayment cemented together or of a self-adhering polymer modified bitumen sheet, be used in lieu of normal underlayment and extend from the eave's edge to a point at least 24 inches inside the exterior wall line of the building," and adds "Ice barrier protection at eaves is required in Minnesota." North St. Paul has no power to waive it (Minn. Stat. 326B.121, subd. 2(c)).
City of Oakdale, Minnesota - Building Inspection & Code Enforcement (City of Oakdale, Minnesota)
Required by the State Building Code across Minnesota. Minnesota Rules part 1309.0301, subpart 2 rewrites IRC Table R301.2(1), Climatic and Geographic Design Criteria, for the whole state, and its ICE BARRIER UNDERLAYMENT REQUIRED entry reads Yes. The Minnesota Department of Labor and Industry's guidance sheet describes the barrier: "an ice barrier that consists of at least two layers of underlayment cemented together or of a self-adhering polymer modified bitumen sheet, be used in lieu of normal underlayment and extend from the eave's edge to a point at least 24 inches inside the exterior wall line of the building," and adds "Ice barrier protection at eaves is required in Minnesota." Oakdale has no power to waive it (Minn. Stat. 326B.121, subd. 2(c)).
City of Orono, Minnesota - Community Development (City of Orono, Minnesota)
Required by the State Building Code across Minnesota. Minnesota Rules part 1309.0301, subpart 2 rewrites IRC Table R301.2(1), Climatic and Geographic Design Criteria, for the whole state, and its ICE BARRIER UNDERLAYMENT REQUIRED entry reads Yes. The Minnesota Department of Labor and Industry's guidance sheet describes the barrier: "an ice barrier that consists of at least two layers of underlayment cemented together or of a self-adhering polymer modified bitumen sheet, be used in lieu of normal underlayment and extend from the eave's edge to a point at least 24 inches inside the exterior wall line of the building," and adds "Ice barrier protection at eaves is required in Minnesota." Orono has no power to waive it (Minn. Stat. 326B.121, subd. 2(c)).
City of Plymouth, Minnesota - Building Inspection Division (City of Plymouth, Minnesota)
STATE-GOVERNED, NOT CITY-SET -- applies identically in Plymouth as everywhere else in Minnesota. Minnesota Rules part 1309.0301, subpart 2 amends IRC Table R301.2(1) ("Climatic and Geographic Design Criteria") to pre-fill "ICE BARRIER UNDERLAYMENT REQUIRED[h] ... Yes" for the entire state. A Minnesota DLI consumer guidance sheet ("Asphalt Shingle Roofing and the 2020 Minnesota Residential Code," Construction Codes and Licensing Division) hosted on Plymouth's own website states directly: "Ice barrier protection at eaves is required in Minnesota," using "an ice barrier that consists of at least two layers of underlayment cemented together or of a self-adhering polymer modified bitumen sheet... extend[ing] from the eave's edge to a point at least 24 inches inside the exterior wall line of the building." On slopes between 2:12 and 4:12, the sheet notes "a double underlayment application in accordance with Section R905.2.7" is required due to greater ice-dam risk. Plymouth has no authority to opt out of this (Minn. Stat. § 326B.121, subd. 2(c)). GARAGE NUANCE: an older (2015-vintage, drafted against the now-superseded 2015 MSBC/2012 IRC -- staleness caveat applies) Plymouth "Reroofing Information Sheet" states the ice-barrier exception as: "Detached accessory structures (garages and storage buildings) that contain no conditioned floor areas are not required to have an ice barrier" -- i.e. the exemption turns on CONDITIONED status, not simply attached/detached. The Bloomington, MN record frames it the same way ("required for all attached garages and for all detached HEATED garages"), while Maple Grove, MN's own current roofing handout exempts "detached accessory buildings (garages)" with no heated/conditioned qualifier at all. Because ice-barrier applicability is state-governed code content rather than a city choice, confirm garage-specific applicability with the Building Inspection Division before relying on a blanket detached-garage exemption.
City of Prior Lake, Minnesota - Building Inspections Division (City of Prior Lake, Minnesota)
Required by the State Building Code across Minnesota. Minnesota Rules part 1309.0301, subpart 2 rewrites IRC Table R301.2(1), Climatic and Geographic Design Criteria, for the whole state, and its ICE BARRIER UNDERLAYMENT REQUIRED entry reads Yes. The Minnesota Department of Labor and Industry's guidance sheet describes the barrier: "an ice barrier that consists of at least two layers of underlayment cemented together or of a self-adhering polymer modified bitumen sheet, be used in lieu of normal underlayment and extend from the eave's edge to a point at least 24 inches inside the exterior wall line of the building," and adds "Ice barrier protection at eaves is required in Minnesota." Prior Lake has no power to waive it (Minn. Stat. 326B.121, subd. 2(c)).
City of Ramsey, Minnesota - Building Division (City of Ramsey, Minnesota)
Required by the State Building Code across Minnesota. Minnesota Rules part 1309.0301, subpart 2 rewrites IRC Table R301.2(1), Climatic and Geographic Design Criteria, for the whole state, and its ICE BARRIER UNDERLAYMENT REQUIRED entry reads Yes. The Minnesota Department of Labor and Industry's guidance sheet describes the barrier: "an ice barrier that consists of at least two layers of underlayment cemented together or of a self-adhering polymer modified bitumen sheet, be used in lieu of normal underlayment and extend from the eave's edge to a point at least 24 inches inside the exterior wall line of the building," and adds "Ice barrier protection at eaves is required in Minnesota." Ramsey has no power to waive it (Minn. Stat. 326B.121, subd. 2(c)).
City of Richfield, Minnesota - Inspections Division (City of Richfield, Minnesota)
Required by the State Building Code across Minnesota. Minnesota Rules part 1309.0301, subpart 2 rewrites IRC Table R301.2(1), Climatic and Geographic Design Criteria, for the whole state, and its ICE BARRIER UNDERLAYMENT REQUIRED entry reads Yes. The Minnesota Department of Labor and Industry's guidance sheet describes the barrier: "an ice barrier that consists of at least two layers of underlayment cemented together or of a self-adhering polymer modified bitumen sheet, be used in lieu of normal underlayment and extend from the eave's edge to a point at least 24 inches inside the exterior wall line of the building," and adds "Ice barrier protection at eaves is required in Minnesota." Richfield has no power to waive it (Minn. Stat. 326B.121, subd. 2(c)).
City of Rochester, Minnesota - Building Safety Division (City of Rochester, Minnesota)
STATE-GOVERNED, NOT CITY-SET -- applies identically in Rochester as everywhere else in Minnesota, because Rochester adopts the Minnesota State Building Code without local amendment (see adopted_code). Minnesota Rules part 1309.0301, subpart 2 amends IRC Table R301.2(1) to pre-fill "ICE BARRIER UNDERLAYMENT REQUIRED[h] ... Yes" for the entire state; footnote h cross-references IRC Sections R905.1.2, R905.2.7, R905.4.3.1, R905.5.3.1, R905.6.3.1, R905.7.3.1 and R905.8.3.1 for the applicable ice-barrier standard. Rochester has no authority to opt out of this (Minn. Stat. § 326B.121, subd. 2(c)). GARAGE NUANCE: because this is a state-level pre-filled table entry, no Rochester-specific garage exemption is established in this record; confirm garage-specific applicability with Building Safety before relying on any blanket exemption.
City of Rogers, Minnesota - Building Department (City of Rogers, Minnesota)
Required by the State Building Code across Minnesota. Minnesota Rules part 1309.0301, subpart 2 rewrites IRC Table R301.2(1), Climatic and Geographic Design Criteria, for the whole state, and its ICE BARRIER UNDERLAYMENT REQUIRED entry reads Yes. The Minnesota Department of Labor and Industry's guidance sheet describes the barrier: "an ice barrier that consists of at least two layers of underlayment cemented together or of a self-adhering polymer modified bitumen sheet, be used in lieu of normal underlayment and extend from the eave's edge to a point at least 24 inches inside the exterior wall line of the building," and adds "Ice barrier protection at eaves is required in Minnesota." Rogers has no power to waive it (Minn. Stat. 326B.121, subd. 2(c)).
City of Rosemount, Minnesota - Building Permits and Inspections Department (City of Rosemount, Minnesota)
Required by the State Building Code across Minnesota. Minnesota Rules part 1309.0301, subpart 2 rewrites IRC Table R301.2(1), Climatic and Geographic Design Criteria, for the whole state, and its ICE BARRIER UNDERLAYMENT REQUIRED entry reads Yes. The Minnesota Department of Labor and Industry's guidance sheet describes the barrier: "an ice barrier that consists of at least two layers of underlayment cemented together or of a self-adhering polymer modified bitumen sheet, be used in lieu of normal underlayment and extend from the eave's edge to a point at least 24 inches inside the exterior wall line of the building," and adds "Ice barrier protection at eaves is required in Minnesota." Rosemount has no power to waive it (Minn. Stat. 326B.121, subd. 2(c)).
City of Roseville, Minnesota - Building Division (City of Roseville, Minnesota)
STATE-GOVERNED, NOT CITY-SET — the requirement applies identically in Roseville as everywhere else in Minnesota. Minnesota Rules part 1309.0301, subpart 2 amends IRC Table R301.2(1) ("Climatic and Geographic Design Criteria") to pre-fill "ICE BARRIER UNDERLAYMENT REQUIRED[h] ... Yes" for the entire state. The Minnesota Department of Labor and Industry's guidance sheet, "Asphalt Shingle Roofing and the 2020 Minnesota Residential Code," describes what satisfies it: an ice barrier "may be at least two layers of underlayment cemented together or a self-adhering polymer modified bitumen sheet," extending from the eave edge to a point at least 24 inches inside the exterior wall line of the building. Roseville has no authority to opt out (Minn. Stat. 326B.121, subd. 1 makes the State Building Code the standard that applies statewide and provides that it supersedes the building code of any municipality, and subd. 2(c) bars a municipality from requiring building code provisions regulating components or systems of a structure that differ from the State Building Code). Garage and detached-accessory-structure applicability is worded differently by different Minnesota cities — Apple Valley exempts "unheated detached accessory structures" while Maplewood and Minnetonka exempt detached accessory buildings with no heated qualifier — so confirm that specific case with the building department rather than assuming a blanket detached-garage exemption.
City of Saint Paul, Minnesota - Department of Safety and Inspections (DSI) (City of Saint Paul, Minnesota)
STATE-GOVERNED, NOT CITY-SET -- applies identically in Saint Paul as everywhere else in Minnesota. Minnesota Rules part 1309.0301, subpart 2 amends IRC Table R301.2(1) ("Climatic and Geographic Design Criteria") to pre-fill "ICE BARRIER UNDERLAYMENT REQUIRED[h] ... Yes" for the entire state -- footnote h ties this to IRC Sections R905.1.2 etc. "where there has been a history of local damage from the effects of ice damming," a determination Minnesota has made statewide by rule rather than leaving to municipal option. Saint Paul has no authority to opt out of this (Minn. Stat. § 326B.121, subd. 2(c)). The literal installation-extent text of R905.1.2 itself is unamended base 2018 IRC text and is not reproduced here; refer to the 2018 IRC for the installation extent.
City of Shakopee, Minnesota - Building Inspections (City of Shakopee, Minnesota)
STATE-GOVERNED, NOT CITY-SET — the requirement applies identically in Shakopee as everywhere else in Minnesota. Minnesota Rules part 1309.0301, subpart 2 amends IRC Table R301.2(1) ("Climatic and Geographic Design Criteria") to pre-fill "ICE BARRIER UNDERLAYMENT REQUIRED[h] ... Yes" for the entire state. The Minnesota Department of Labor and Industry's guidance sheet, "Asphalt Shingle Roofing and the 2020 Minnesota Residential Code," describes what satisfies it: an ice barrier "may be at least two layers of underlayment cemented together or a self-adhering polymer modified bitumen sheet," extending from the eave edge to a point at least 24 inches inside the exterior wall line of the building.

Garage and detached-accessory-structure applicability is worded differently by different Minnesota cities — Apple Valley exempts "unheated detached accessory structures" while Maplewood and Minnetonka exempt detached accessory buildings with no heated qualifier — so confirm that specific case with the building department rather than assuming a blanket detached-garage exemption.
City of South St. Paul, Minnesota - Building Permit and Inspections Department (City of South St. Paul, Minnesota)
Required by the State Building Code across Minnesota. Minnesota Rules part 1309.0301, subpart 2 rewrites IRC Table R301.2(1), Climatic and Geographic Design Criteria, for the whole state, and its ICE BARRIER UNDERLAYMENT REQUIRED entry reads Yes. The Minnesota Department of Labor and Industry's guidance sheet describes the barrier: "an ice barrier that consists of at least two layers of underlayment cemented together or of a self-adhering polymer modified bitumen sheet, be used in lieu of normal underlayment and extend from the eave's edge to a point at least 24 inches inside the exterior wall line of the building," and adds "Ice barrier protection at eaves is required in Minnesota." South St. Paul has no power to waive it (Minn. Stat. 326B.121, subd. 2(c)).
City of St. Cloud, Minnesota - Building Safety Division (City of St. Cloud, Minnesota)
STATE-GOVERNED, and restated in St. Cloud's own guidance. Minnesota Rules part 1309.0301, subpart 2 amends IRC Table R301.2(1) to pre-fill an ice-barrier-underlayment requirement statewide. St. Cloud's own "Residential Reroof" handout (Building Safety Department), citing R905.1.2, states: "Ice/water barrier is required on all roofs, except for a detached accessory structure with no conditioned floor area. Ice/water barrier is required to consist of at least two layers of underlayment cemented together or a self-adhering polymer modified bitumen sheet. The ice/water barrier shall be used in place of normal underlayment and extend from the lowest edge of all roof surfaces to a point at least 24 inches inside the exterior wall line of the building. On roofs with a slope equal to or greater than 8/12, the ice barrier shall also be applied not less than 36 [inches] measured along the roof slope from the eave edge of the building."
City of St. Francis, Minnesota - Building Department (City of St. Francis, Minnesota)
Required by the State Building Code across Minnesota. Minnesota Rules part 1309.0301, subpart 2 rewrites IRC Table R301.2(1), Climatic and Geographic Design Criteria, for the whole state, and its ICE BARRIER UNDERLAYMENT REQUIRED entry reads Yes. The Minnesota Department of Labor and Industry's guidance sheet describes the barrier: "an ice barrier that consists of at least two layers of underlayment cemented together or of a self-adhering polymer modified bitumen sheet, be used in lieu of normal underlayment and extend from the eave's edge to a point at least 24 inches inside the exterior wall line of the building," and adds "Ice barrier protection at eaves is required in Minnesota." St. Francis has no power to waive it (Minn. Stat. 326B.121, subd. 2(c)).
City of St. Louis Park, Minnesota - Building and Energy Department (City of St. Louis Park, Minnesota)
STATE-GOVERNED, NOT CITY-SET — the requirement applies identically in St. Louis Park as everywhere else in Minnesota. Minnesota Rules part 1309.0301, subpart 2 amends IRC Table R301.2(1) ("Climatic and Geographic Design Criteria") to pre-fill "ICE BARRIER UNDERLAYMENT REQUIRED[h] ... Yes" for the entire state. The Minnesota Department of Labor and Industry's guidance sheet, "Asphalt Shingle Roofing and the 2020 Minnesota Residential Code," describes what satisfies it: an ice barrier "may be at least two layers of underlayment cemented together or a self-adhering polymer modified bitumen sheet," extending from the eave edge to a point at least 24 inches inside the exterior wall line of the building. St. Louis Park has no authority to opt out (Minn. Stat. 326B.121, subd. 1 makes the State Building Code the standard that applies statewide and provides that it supersedes the building code of any municipality, and subd. 2(c) bars a municipality from requiring building code provisions regulating components or systems of a structure that differ from the State Building Code). Garage and detached-accessory-structure applicability is worded differently by different Minnesota cities — Apple Valley exempts "unheated detached accessory structures" while Maplewood and Minnetonka exempt detached accessory buildings with no heated qualifier — so confirm that specific case with the building department rather than assuming a blanket detached-garage exemption.
City of Victoria, Minnesota - Building Department (City of Victoria, Minnesota)
Required by the State Building Code across Minnesota. Minnesota Rules part 1309.0301, subpart 2 rewrites IRC Table R301.2(1), Climatic and Geographic Design Criteria, for the whole state, and its ICE BARRIER UNDERLAYMENT REQUIRED entry reads Yes. The Minnesota Department of Labor and Industry's guidance sheet describes the barrier: "an ice barrier that consists of at least two layers of underlayment cemented together or of a self-adhering polymer modified bitumen sheet, be used in lieu of normal underlayment and extend from the eave's edge to a point at least 24 inches inside the exterior wall line of the building," and adds "Ice barrier protection at eaves is required in Minnesota." Victoria has no power to waive it (Minn. Stat. 326B.121, subd. 2(c)).
City of West St. Paul, Minnesota - Building Permits & Inspections (City of West St. Paul, Minnesota)
Required by the State Building Code across Minnesota. Minnesota Rules part 1309.0301, subpart 2 rewrites IRC Table R301.2(1), Climatic and Geographic Design Criteria, for the whole state, and its ICE BARRIER UNDERLAYMENT REQUIRED entry reads Yes. The Minnesota Department of Labor and Industry's guidance sheet describes the barrier: "an ice barrier that consists of at least two layers of underlayment cemented together or of a self-adhering polymer modified bitumen sheet, be used in lieu of normal underlayment and extend from the eave's edge to a point at least 24 inches inside the exterior wall line of the building," and adds "Ice barrier protection at eaves is required in Minnesota." West St. Paul has no power to waive it (Minn. Stat. 326B.121, subd. 2(c)).
City of Woodbury, Minnesota - Building Inspections Division (City of Woodbury, Minnesota)
STATE-GOVERNED, NOT CITY-SET -- applies identically in Woodbury as everywhere else in Minnesota, because Woodbury adopts the Minnesota State Building Code without local amendment on this point (see adopted_code). Minnesota Rules part 1309.0301, subpart 2 amends IRC Table R301.2(1) to pre-fill "ICE BARRIER UNDERLAYMENT REQUIRED[h] ... Yes" for the entire state; footnote h cross-references IRC Sections R905.1.2, R905.2.7, R905.4.3.1, R905.5.3.1, R905.6.3.1, R905.7.3.1 and R905.8.3.1 for the applicable ice-barrier standard. Woodbury has no authority to opt out of this (Minn. Stat. § 326B.121, subd. 2(c)). Woodbury's own Roofing Information Handout independently corroborates an ice-dam rule locally: "Ice dam protection is required on all roofs and shall extend from the edge of the roof 24" past the exterior wall line." GARAGE NUANCE: because the state table entry is a uniform pre-fill, no Woodbury-specific garage exemption has been on record; confirm garage-specific applicability with Building Inspections before relying on any blanket exemption.
Ice barrier required — Missouri (14)
Cass County Building Codes Department (Cass County, Missouri)
Cass County Building Codes Department amendments to the 2006 I-Codes ("Last Updated December 28, 2009," effective 1/1/2010) insert values into IRC Table R301.2(1), Climatic and Geographic Design Criteria, including "Ice Barrier Underlayment ... Yes." The county's amendment document does not separately amend IRC Chapter 9 (Roof Assemblies), so the requirement operates under the standard, unamended 2006 IRC ice-barrier extent provision (membrane extending from the lowest roof edge to not less than 24 inches inside the exterior wall line).
City of Belton - Community Development Department (City of Belton, Missouri)
City of Belton UDC Sec. 10-5, "Adoption of International Residential Code for One- and Two-Family Dwellings, 2018 edition, with local amendments" (Ord. No. 2022-4738, § 2, adopted 9-27-2022), amends Table R301.2(1), Climatic and Geographic Design Criteria, inserting "Ice Barrier required - Yes." The City's Inspection Guidebook separately lists ice and water shield as an inspected roofing component ("Sheathing, ice and water shield and underlayment, drip edge, valleys, and venting installed to adopted codes"). Belton's Sec. 10-5 amendments do not separately touch IRC Section R905 (Roof Assemblies), so the standard 2018 IRC ice-barrier extent provision (membrane extending from the lowest roof edge to not less than 24 inches inside the exterior wall line) applies unamended.
City of Blue Springs - Community Development Department (Codes Administration Division) (City of Blue Springs, Missouri)
Table R301.2(1) Climatic and Geographic Design Criteria, as amended in the adopted International Residential Code, states: "Ice Barrier Underlayment Required: Yes." (Ordinance No. 5480, amending Code of Ordinances Section 500.010(A)(7)(a), adopting the 2024 IRC, passed by the Blue Springs City Council February 18, 2026.)
City of Florissant, Missouri - Department of Public Works (Building Department) (City of Florissant, Missouri)
Florissant's Table R301.2(1) Climatic and Geographic Design Criteria (as amended) lists "Ice Barrier Underlayment Required" as "YES," with the table's own footnote h stating: "In accordance with Sections R905.1.2, R905.4.3.1, R905.5.3.1, R905.6.3.1, R905.7.3.1 and R905.8.3.1: The jurisdiction shall fill in this part of the table with 'YES.' Exemption applies to houses built after January 1, 2023." The table repeats this in expanded form: "Ice Shield Underlayment Required - YES." So ice barrier/ice-and-water-shield underlayment IS required as a blanket rule EXCEPT for houses built after January 1, 2023, which are exempt -- a Florissant-specific new-construction carve-out that a roofer should confirm against the house's construction/permit date before assuming the requirement applies.
City of Gladstone, Missouri - Community Development Department (Building and Construction Division) (City of Gladstone, Missouri)
"Ice barrier is require[d] for all roofing and reroofing. Ice barrier shall consist of 2-layers of underlayment cemented together or a self-adhering polymer modified bitumen sheet. Ice barrier shall extend from the lowest edges of all roof surfaces to a point at least twenty-four (24) inches inside the exterior wall line of the building." Stated identically for both Residential and Commercial, with no history-of-ice-damming trigger language -- a blanket requirement on every roof/reroof. Corroborated by Table R301.2 of Chapter 200 (BACO), adopting the 2021 IRC, which lists "Ice Barrier Underlayment Required: Yes."
City of Grain Valley - Community Development Department (City of Grain Valley, Missouri)
Section 500.100.C.4, Table R301.2(1) as amended, states: "Ice Shield Underlayment Required: Yes." (City of Grain Valley Code of Ordinances, adopting the 2018 IRC effective May 1, 2021, per Ordinance No. 2550, 7-26-2021.)
City of Grandview - Building Services Division (City of Grandview, Missouri)
The city's own amended Table R301.2(1), codified at Sec. 10-25(2) (Residential code amendments, within the 2018 IRC adopted at Sec. 10-23(a)(2), most recently amended by Ord. No. 7282, §§ 1-8, 1-12-2021), lists "Ice Barrier Underlayment Required ... Yes" among the table's climatic/geographic design criteria entries.
City of Independence, Missouri - Building Inspections Division (City of Independence, Missouri)
Table R301.2(1) Climatic and Geographic Design Criteria, as amended by the ordinance adopting the 2018 IRC (effective 1/1/2019), states: "Ice Barrier Underlayment: Yes, installed as required by section 905.1.2." Section R905.1.2 requires the ice barrier to extend from the lowest edges of the roof to a point not less than 24 inches inside the exterior wall line of the building.
City of Kansas City, Missouri - City Planning & Development Department (City of Kansas City, Missouri)
Kansas City's amended IRC Table R301.2(1) (Code of Ordinances Sec. 18-57, Article III, Residential Code) lists "ICE BARRIER UNDERLAYMENT REQUIRED: Yes" (Winter Design Temp 6F, Air Freezing Index 1000). Under the unamended 2018 IRC R905.1.2 baseline this extends from the eave edge to 24 in. inside the exterior wall line on all eaves. Architect-verified directly on the current municode codification, 2026-07-19.
City of Lee's Summit - Development Services Department (City of Lee's Summit, Missouri)
The city's own Table R301.2(1) data entry, codified in Sec. 7-902 of the Lee's Summit Building Code (Ord. No. 8584, § 1, adopted 3-19-2019, effective 4-1-2019), lists "Ice Barrier Underlayment Requirement ... Yes." Section R905.1.2 (Ice barriers), which supplies the trigger language for that "Yes" -- "an ice barrier ... shall be installed ... and shall extend from the lowest edges of all roof surfaces to a point not less than 24 inches inside the exterior wall line of the building" -- is adopted as part of the 2018 IRC (Sec. 7-900) and is not amended or altered anywhere in Article IX.
City of Liberty - Building Division (City of Liberty, Missouri)
"2018 IBC Section 1507.6.4 Ice barrier. In areas where there has been a history of ice forming along the eaves causing a backup of water, an ice barrier that consists of at least two layers of underlayment cemented together or of a self-adhering polymer-modified bitumen sheet shall be used in lieu of normal underlayment and extend from the lowest edges of all roof surfaces to a point at least 24 inches inside the exterior wall line of the building. Exception: Detached accessory structures that contain no conditioned floor area." (City of Liberty Planning and Development Department, "Ice Barrier Requirements," updated 3/5/2021; the city states it "enforces Chapter 9 of the IRC and Chapter 15 of the IBC as it pertains to 'Ice and Water Shield' requirements... as written.") Corroborated by Table R301.2 of Ordinance No. 11358 (adopting the 2018 IRC, passed/approved 2/22/2021), which lists "Ice Barrier Underlayment Required: Yes."
City of North Kansas City - Community Development Department (City of North Kansas City, Missouri)
"Table R301.2(l) is amended as follows: ... Ice Shield Underlayment Required: Yes" (North Kansas City Code of Ordinances Sec. 15.26.020, Amendments to Residential Code, amending the 2018 IRC Table R301.2(1); section last modified by Ord. No. 9743, 11-4-2025). The amendment does not condition the "Yes" on elevation, slope, or any other factor beyond the citywide table entry.
City of Raytown - Community Development Department (Building Inspections) (City of Raytown, Missouri)
The city's own amended Table R301.2(1), codified at Sec. 8-137 (Amendments to residential code, within the 2018 IRC adopted at Sec. 8-136, most recently amended by Ord. No. 5617-19, § 1, 10-15-2019), lists "Ice Barrier Underlayment Required = YES" among the table's climatic/geographic design criteria entries.
Clay County - Planning & Zoning Department (Clay County, Missouri)
The same letter states: "Section 905.2.7.1 - Ice Barrier - Table 301.2(1) requires each jurisdiction to indicate through its weather history the need for ice barrier. Clay County does require the adherence of an ice barrier application (one of two methods in the code)." The attached 2012 IRC R905.2.7.1 text furnished in the same document reads: "In areas where there has been a history of ice forming along the eaves causing a backup of water..., an ice barrier that consists of a least two layers of underlayment cemented together or of a self-adhering polymer modified bitumen sheet shall be used in lieu of normal underlayment and extend from the lowest edges of all roof surfaces to a point at least 24 inches (610 mm) inside the exterior wall line of the building. Exception: Detached accessory structures that contain no conditioned floor area."
Ice barrier required — Montana (7)
Butte-Silver Bow, Montana - Building & Code Enforcement (City and County of Butte-Silver Bow, Montana)
Montana's amended 2021 IRC makes ice-barrier underlayment mandatory statewide, not only where a history of ice damming is shown. ARM 24.301.154(23) amends Section R905.1.2 by deleting the model code's geographic trigger, "areas where there has been a history of ice forming along the eaves causing a backup of water as designated in Table R301.2," and inserting "the State of Montana." That state amendment reaches a house here only because Butte-Silver Bow's own legislative body has expressly extended the code to one- and two-family dwellings: Municipal Code 15.04.075 adopts the 2021 IRC by name specifically for "detached one-and two-family dwellings and townhouses," rather than merely inheriting dwelling coverage from a general building-code adoption. The county's own local amendment chapter does not touch Section R905 or any other Chapter 9 roofing provision, so the statewide ice-barrier rule applies here unmodified.
City of Belgrade Building Department (City of Belgrade, Montana)
REQUIRED STATEWIDE BY A STATE AMENDMENT THAT REPLACES THE MODEL CODE'S GEOGRAPHIC TRIGGER WITH THE WHOLE STATE, AND BELGRADE'S OWN GUIDANCE SAYS THE SAME THING IN PLAIN WORDS. ARM 24.301.154(23), which Belgrade adopts by City Code 8-1-1 ("as amended by ARM 24.301.154"), reads in full: "Subsection R 905.1.2 is amended by deletion of the language 'areas where there has been a history of ice forming along the eaves causing a backup of water as designated in Table R301.2' and insert 'the State of Montana.'" That deletes the model code's local ice-damming finding and substitutes the entire state, so the ice-barrier underlayment requirement applies in Belgrade with no local history-of-ice-damming finding needed. The City's own Building Permit Guidelines corroborate it in plain language, requiring a plan submittal to "Show roof covering materials. Ice barrier required."
City of Billings Building Division (City of Billings, Montana)
REQUIRED STATEWIDE, INCLUDING IN BILLINGS, BY A STATE AMENDMENT THAT NEVER USES THE WORDS "ICE BARRIER." ARM 24.301.154(23) reads in full: "Subsection R 905.1.2 is amended by deletion of the language 'areas where there has been a history of ice forming along the eaves causing a backup of water as designated in Table R301.2' and insert 'the State of Montana.'" The base 2021 IRC's ice-barrier trigger is a local finding of history of ice damming; Montana's amendment replaces that trigger with the whole state, so the ice-barrier membrane required by R905.1.2 applies everywhere the state-amended code reaches a dwelling, Billings included, with no local ice-damming finding needed. Billings' own ordinance does not touch R905.1.2.
City of Havre Public Works Department (City of Havre, Montana)
REQUIRED STATEWIDE BY THE STATE'S OWN AMENDMENT, WITH NO LOCAL-HAZARD FINDING NEEDED. ARM 24.301.154(23), in its entirety: "Subsection R 905.1.2 is amended by deletion of the language 'areas where there has been a history of ice forming along the eaves causing a backup of water as designated in Table R301.2' and insert 'the State of Montana.'" The model code's geographic ice-damming trigger is replaced with the whole state, so wherever the state-amended residential code reaches a house, the ice-barrier underlayment requirement at R905.1.2 applies regardless of any local finding. Havre's 4-1-15 applicability clause extends the code, including this amendment, to "residential buildings containing less than five (5) dwelling units." Havre's own building chapter states no contrary rule.
City of Kalispell Building Department (City of Kalispell, Montana)
Required, on two independent bases. Statewide, ARM 24.301.154(23) amends IRC R905.1.2 by deleting the model code's geographic trigger and inserting the whole state: "Subsection R905.1.2 is amended by deletion of the language 'areas where there has been a history of ice forming along the eaves causing a backup of water as designated in Table R301.2' and insert 'the State of Montana.'" And directly: the City's own Construction Design Criteria table (its filled-in IRC Table R301.2(1)) states "ICE BARRIER UNDERLAYMENT REQUIRED: YES."
City of Laurel, Montana Building Department (City of Laurel, Montana)
REQUIRED ON THE CITY'S OWN DIRECT STATEMENT TO APPLICANTS, WHICH DOES NOT DEPEND ON THE UNRESOLVED APPLICABILITY QUESTION IN adopted_code. The City's own Requirements for Roofing letter, issued by the Building Department on City Hall letterhead in the identical wording for both its residential and commercial versions, states plainly: "Ice barriers are required per section R905.1.2 of the 2021 International Residential Code and section 1507.1.2 of the 2021 International Building Code." That is the City's own affirmative instruction to a person pulling a roofing permit here, and it is the basis for this field -- the same kind of direct, jurisdiction-side evidence that establishes roofing_permit_required, independent of whether Laurel's general code adoption also satisfies MCA 50-60-102(1)(a)'s "specifically applicable" test. Montana's statewide IRC amendment, ARM 24.301.154(23), separately rewrites the model code's geographic trigger for the ice barrier to read "the State of Montana," which corroborates but is not needed to carry this field. Neither instrument modifies the underlayment specification or the required extent up the roof slope beyond that trigger, so take that detail from the base 2021 IRC R905.1.2 text.
Livingston Building Department (City of Livingston, Montana)
Montana's own amendment rule, ARM 24.301.154(23), rewrites the 2021 IRC's ice-barrier trigger, Section R905.1.2, deleting its geographic history-of-ice-damming clause and inserting "the State of Montana" in its place, so the ice-barrier underlayment requirement applies statewide with no local finding needed. Livingston's Ordinance No. 3035 adopts the 2021 IRC as amended by the department and makes it applicable to one- and two-family dwellings by name.
Ice barrier required — Nebraska (17)
City of Beatrice - Community Development Department (City of Beatrice, Nebraska)
Beatrice amended the ice barrier rule and made it dimensionally its own. Beatrice City Code Sec. 7-56 rewrites IRC Section R905.1.2: "In areas where there has been a history of ice forming along the eaves causing a backup of water as designated in table R301.2(1), an ice barrier shall be installed for asphalt shingles, metal roof shingles, mineral-surfaced roll roofing, slate and slate-type shingles, wood shingles and wood shakes. The ice barrier shall consist of not fewer than two (2) layers of underlayment cemented together, or a self-adhering polymer-modified bitumen sheet shall be used in place of normal underlayment and extend from the lowest edges of all roof surfaces to a point not less than thirty-six (36) inches (six hundred ten millimeters (610 mm)) upward towards the roof peak. On roofs with slope equal to or greater than eight (8) units vertical in twelve (12) units horizontal, the ice barrier shall also be applied not less than thirty-six (36) inches (nine hundred fourteen and four-tenths millimeters (914.4 mm)) measured along the roof slope from the eave edge of the building." Two things to carry from that. Beatrice measures the barrier upward toward the roof peak rather than to a point inside the exterior wall line. And the city's text prints two different metric conversions for the same thirty-six inch figure, 610 mm at the first instance and 914.4 mm at the second, of which only 914.4 mm equals thirty-six inches; confirm the intended dimension with the Community Development Department before a plan review turns on it. The city's published Table R301.2(1) supplies the trigger the section refers to, listing "Ice Barrier Underlayment Required" as Yes, with an asterisk keyed to this amended section, and reprints the amended text with the same two conversions.
City of Bellevue - Permits and Inspection Division (City of Bellevue, Nebraska)
Bellevue's amended IRC Table R301.2, Climatic and Geographic Design Criteria (Bellevue City Code § 8-18.6(B), Ord. 4033, passed 5-4-2021), lists "Ice Barrier Required" as "YES" for the city.
City of Columbus, NE - Community Development Department (City of Columbus, Nebraska)
The City of Columbus amends the model code's climatic and geographic design criteria table into its own ordinance, and that table reads "Ice Barrier Underlayment Required Yes" (Ordinance No. 20-29, amending Table R301.2(1) of the 2018 International Residential Code, Columbus City Code Section 150.106). The ordinance sets no local variation on where the barrier must extend to, and it amends no section of Chapter 9 of the code it adopted, so the ice-barrier provisions of the adopted 2018 International Residential Code apply unmodified.
City of Fremont - Department of Building Safety (City of Fremont, Nebraska)
Fremont fills in the ice-barrier column of its own climate table. Fremont Municipal Code Section 9-402(h) amends "Table R301.2(1) Climatic And Geographic Design Criteria" and prints "Ice Barrier Underlayment Required" as "Yes." The table reproduces the model footnote h that governs that column: "In accordance with Sections R905.1.2, R905.4.3.1, R905.5.3.1, R905.6.3.1, R905.7.3.1 and R905.8.3.1, where there has been a history of local damage from the effects of ice damming, the jurisdiction shall fill in this part of the table with 'YES.'" Fremont's amendment list does not touch R905.1.2 or any other section of IRC Chapter 9 except R908, so the base 2018 IRC ice-barrier provisions apply unmodified; read R905.1.2 and the covering-specific sections named in footnote h for the required extent and materials.
City of Gering - Building Inspection (Engineering & Planning Department) (City of Gering, Nebraska)
Required, and Gering says so twice. Its Roofing Inspections and Requirements sheet, item 4, reads: "Ice barrier is required to be installed over solid sheet. This area is required to have ice barrier by code and must be solidly sheathe to the roof. All roofs are required to have ice and water barrier. Minimum of 24 inches inside of exterior walls." Separately, the climatic and geographic design criteria table the City publishes for its adopted code answers "Yes" in the ICE BARRIER UNDERLAYMENT REQUIRED column, which is the entry the adopted code keys its ice-barrier provision to. Read the 24-inch figure as the City states it - measured to inside the exterior wall line, not from the eave edge.
City of Gretna - Building & Zoning Department (City of Gretna, Nebraska)
Required, and Gretna states it twice from two directions. The City's amended Table R301.2(1), enacted by Ordinance No. 2141, publishes "ICE BARRIER UNDERLAYEMENT REQUIRED - YES" for Gretna, which is the trigger the adopted 2021 IRC keys its ice-barrier provision to. Separately, the Building & Zoning FAQ attaches the ice shield to the roofing work rather than to the permit: its list of work for which a permit is NOT required exempts "Roofing projects that do not involve rafters or installation or replacement of more than one sheet of decking. (such as re-shingling)" and adds in the same entry "Note: Ice shield must be installed." A re-shingle that the department treats as permit-exempt therefore still has to carry the ice barrier.
City of Hastings - Development Services (City of Hastings, Nebraska)
Hastings City Code section 8-602 amends Table R301.2(1) of the 2018 International Residential Code to the city's own figures, and that table states "Ice Barrier Underlayment Required: Yes" for the City of Hastings. That entry is what switches on the ice-barrier requirement in Chapter 9 of the adopted 2018 IRC; section 8-602's amendment list, read in full, changes no section of Chapter 9, so the code's ice-barrier provision applies as written. The same table records a Winter Design Temp of -3 F and Weathering "Severe," which is the climate the requirement answers to.
City of Lexington, NE - Development Services Department (City of Lexington, Nebraska)
The City's Roof Permit Steps handout states: "After ripping the old shingles off, or on a new roof, an ice barrier must be installed below the shingles," and reproduces the 2015 IRC provision it enforces: "R905.1.2 Ice barriers. In areas where there has been a history of ice forming along the eaves causing a backup of water as designated in Table R301.2(1), an ice barrier shall be installed for asphalt shingles, metal roof shingles, mineral-surfaced roll roofing, slate and slate-type shingles, wood shingles and wood shakes. The ice barrier shall consist of not fewer than two layers of underlayment cemented together, or a self-adhering polymer-modified bitumen sheet shall be used in place of normal underlayment and extend from the lowest edges of all roof surfaces to a point not less than 24 inches (610 mm) inside the exterior wall line of the building. On roofs with slope equal to or greater than 8 units vertical in 12 units horizontal, the ice barrier shall also be applied not less than 36 inches (914 mm) measured along the roof slope from the eave edge of the building." The City states the requirement flatly for reroofs and new roofs rather than conditioning it on a jurisdictional history finding.
City of Lincoln - Building & Safety Department (City of Lincoln, Nebraska)
"Ice Barrier is required for all spaces. (R905.1.2) The self-adhering sheet shall extend from lowest edges of all roof surfaces to a point not less than 24” inside the exterior wall line of the building." (City of Lincoln Building & Safety, Re-Roof Policy, rev. 12/10/2021). Corroborated by the city's own amended climate-criteria table, which lists "Ice Barrier Underlayment Required: Yes" (Lincoln Municipal Code 20.12.140, Table R301.2 Amended; Climatic and Geographic Design Criteria, Ord. 21820 §5, Dec. 15, 2025).
City of Nebraska City - Building & Zoning (City of Nebraska City, Nebraska)
Required, and it is the City's own enacted answer rather than a default. In Municipal Code 9-19, under the heading "Table No. R301.2(1) Amended; Climatic and Geographic Design Criteria.", Nebraska City has filled in the residential code's climatic and geographic design criteria table with its own values. The row as printed gives, in the table's column order: ground snow load 25 psf; wind speed 90 mph; seismic design category A-B; weathering Severe; frost line depth 42 inches; termite moderate to heavy; winter design temperature -2 degrees F; ice barrier underlayment required Yes; and flood hazards 2011. The City also reproduces the table's own footnote h, which is what gives the answer its force: "In accordance with Sections R905.2.7.1, R905.4.3.1, R905.5.3.1, R905.6.3.1, R905.7.3.1 and R905.8.3.1, where there has been a history of local damage from the effects of ice damming, the jurisdiction shall fill in this part of the table with 'YES.' Otherwise, the jurisdiction shall fill in this part of the table with 'NO.'" Nebraska City filled it in with Yes. So an ice barrier is required on the roof coverings that footnote names - asphalt shingles, metal roof shingles, mineral-surfaced roll roofing, slate and slate-type shingles, wood shingles and wood shakes. The extent of the barrier is set by the base code section for the covering being installed, and this record does not state that figure because the governing edition is itself unsettled here; confirm it with the building official. Note also that the frost line depth of 42 inches and the winter design temperature of -2 degrees F are the City's own figures and are stated in the same table.
City of North Platte - Building & Inspection Department (City of North Platte, Nebraska)
Ordinance No. 4243 of the City of North Platte, adopted January 20, 2026, revised Chapter 150, Section 150.035, "International Residential Code (IRC) Adopted by Reference", by adding an entry to Part III, Chapter 3, Table R301.2(1) Climatic and Geographic Design Criteria. In that entry the column "Ice Barrier Underlayment Required" reads "Yes"; the ordinance strikes through the previous "No" and inserts "Yes" in its place. The City Attorney's staff summary for the ordinance records the reason: "The Building Department has approved the proposed revision to Section 150.035 relating to the ice and water shield. The Building Department was approached by contractors who requested this change based upon interactions with insurance companies." The Council waived the remaining readings and adopted the ordinance the same evening on a unanimous roll call. The ordinance sets the requirement in the climatic-criteria table only; how far up the roof the membrane must run is governed by the adopted residential code, which is not restated in the ordinance.
City of Ogallala - Planning/Zoning, Permits & Building Department (City of Ogallala, Nebraska)
Required, and sourced to the City's own enacted table rather than a separate handout. Section 150.19(B) inserts a filled-in "Part III Chapter 3 Table R301.2 (1) Climatic and Geographic Design Criteria" directly into the codified ordinance, and its ICE BARRIER UNDERLAYMENT REQUIRED column reads "Yes." The same table entry carries a Flood Hazard date of 09-30-1987, an Air Freezing Index of 1500 and a Mean Annual Temp of 50 degrees F, all consistent with a Nebraska Panhandle jurisdiction that expects ice damming.
City of Papillion - Building & Fire Safety Department (City of Papillion, Nebraska)
"Ice and Water Shield (905.1.2): Two layers of Ice and Water shield are required for all roofs." (City of Papillion Roofing Requirements handout, per 2018 IRC Chapter 9). Consistent with the city's amended IRC Table R301.2(1), which lists "Ice Barrier Underlayment Required: Yes" for Papillion (Papillion Municipal Code § 92-15(B), Ordinance No. 1934). The handout's "all roofs" identifies which BUILDINGS the requirement covers, not how far up the slope the barrier runs — the city's ordinance does not amend R905.1.2 itself, so the standard extent (from the eave edge to 24 in. inside the exterior wall line) governs. Confirm extent with the Building Division on unusual roof geometry.
City of Plattsmouth - Building & Zoning (City of Plattsmouth, Nebraska)
Required, and Plattsmouth states its own extent rather than leaving it to the code. The City's ROOFING REQUIREMENTS sheet, dated August 15, 2023, reads under the heading "Ice and Water Shield": "Ice and Water shield is required in the Plattsmouth Building Jurisdiction as we currently are following the 2018 IRC/IBC codes. Ice and Water shield is required to be at a minimum 24 inches up from the finished wall of the structure." Read the 24 inches the way the City words it - measured up from the finished wall of the structure, not from the eave edge - and note that the requirement is stated for the whole Plattsmouth Building Jurisdiction, so it reaches jobs outside the corporate limits but inside the City's zoning jurisdiction. The sheet is signed by Adam Denio, Building and Zoning Administrator, on Plattsmouth City Inspector letterhead.
Lancaster County - Building & Safety (City of Lincoln) (Lancaster County, Nebraska)
"Ice Barrier is required for all spaces. (R905.1.2) The self-adhering sheet shall extend from lowest edges of all roof surfaces to a point not less than 24” inside the exterior wall line of the building." (Re-Roof Policy, rev. 12/10/2021, issued by the City of Lincoln Building & Safety Department under the joint standard: "The City of Lincoln & Lancaster County has adopted and enforces all sections of the 2018 International Residential Code (IRC)... the respective adopted amendments." No separate Lancaster County building department exists; see the paired City of Lincoln, Nebraska record).
Saunders County Planning and Zoning - Building and Zoning Permits (Saunders County, Nebraska)
Saunders County answers this one directly on its own published sheet, which is unusual and useful. The "Climatic and Geographic Design Criteria Saunders County Nebraska" table that Planning and Zoning publishes beside its adopted-codes list carries a column headed "Ice Barrier Underlayment Required for 4/12 or less", and the County's entry in that column is YES. So an ice barrier is required on the roof slopes the column describes. TWO LIMITS ON WHAT THAT TELLS YOU. The County has written its own qualifier into the column heading rather than using the plain "ice barrier underlayment required" wording, so the entry as published speaks to roofs of 4/12 pitch or less and does not by itself state the position on steeper roofs - raise a steeper roof with the Building Inspector rather than reading the YES either way. And the sheet answers whether, not how: the extent an ice barrier must reach up the roof, the materials that qualify and the way it is lapped all come from the 2018 International Residential Code the County has adopted, whose text is behind the International Code Council's paywall and is not restated here. The rest of the County's table, as printed, gives Ground Snow Load 25, Wind Speed (MPH) 115, Seismic Design Category A, Weathering SEVERE, Frost Line Depth 42", Termite M-H, Winter Design Temp -2, Flood Hazards 1982, Air Freezing Index 1624 and Mean Annual Temp 50.6.
Village of Malcolm - Village Clerk (Village of Malcolm, Nebraska)
Malcolm imposes an ice-barrier requirement of its own, on top of whatever the adopted code requires, and it applies to every roofing project rather than only to jobs that need a permit. Item 5 of the Village's Memorandum on Policy and Procedure for Re-Roofing Projects reads in full: "For all roofing projects, the Village of Malcolm hereby requires the installation of underlayment, ice and water shield (i.e. 'ice barrier'), and any flashing at least 24 inches under any adjacent structure sides." Read that beside item 4 of the same memorandum, which sets the baseline: "All roofing projects must adhere to Chapter 15 of the IBC and Chapter 9 of the IRC, which require ice barriers and flashing under certain conditions." The difference between the two is the point of the policy. The adopted code requires an ice barrier under certain conditions; the Village requires underlayment, ice and water shield and flashing for all roofing projects. The memorandum states that it is issued to clarify the position "for owners, contractors, and insurance companies", which is a fair indication of the argument it was written to end. The twenty-four inch figure and the phrase "under any adjacent structure sides" are quoted here exactly as the Village wrote them and are not interpreted. Confirm the measuring point and the extent with the Village Clerk on 402-796-2250 before ordering membrane, and note that the underlying code requirements in the adopted Lincoln codes sit behind the ICC paywall and are not restated on this page. The memorandum was approved by Village Board Chair David Rohe and adopted effective January 8, 2020.
Ice barrier required — North Dakota (11)
Burleigh County, North Dakota - Building/Planning/Zoning Department (Burleigh County, North Dakota)
Sourced from Burleigh County's own published design criteria rather than inferred from the climate, and confirmed twice. The County's Applicable Codes sheet prints a CLIMATIC AND GEOGRAPHIC DESIGN CRITERIA table whose ICE BARRIER UNDERLAYMENT REQUIRED column reads Yes. The County's Frequently Asked Questions page answers the same question directly - "Is Ice Protection Required? Yes." - and adds the history: it states that the requirement "was adopted May 25, 2004." So an ice barrier is required on a Burleigh County re-roof and has been for over twenty years. The County does not restate how far up the slope the barrier must run in either document. Burleigh County's own amendments to the adopted building code, at Article 23, Section 8 of the Zoning Ordinance, do not reach the roofing chapter, and neither do the North Dakota state amendments, so the extent of the barrier is governed by the unamended base residential code - take it from the edition the Building Official confirms is in force for your permit.
City of Bismarck, North Dakota - Building Inspections Department (City of Bismarck, North Dakota)
REQUIRED, AND ON BISMARCK'S OWN AMENDMENT RATHER THAN ON THE STATE DEFAULT OR ON CLIMATE. Bismarck adopts the 2021 International Residential Code at Bismarck Code of Ordinances Section 4-02-02, most recently re-adopted by Ordinance 6544 of March 27, 2023, and carries its own amendments at Section 4-02-06. Under the heading "Table R301.2 CLIMATIC AND GEOGRAPHIC DESIGN CRITERIA (1). Add:", Section 4-02-06 prints a list of the City's own values for Bismarck, and one of its lines reads "Ice Barrier Underlayment Required: YES". That is the City's own enacted text, not an inference from the state's climate. Section 4-02-06 was read in full for this entry - all seven code-by-code amendment blocks, IBC, IRC, IMC, IFGC, IECC and IEBC - and its International Residential Code block amends no section of Chapter 8 (Roof-Ceiling Construction) or Chapter 9 (Roof Assemblies); the highest-numbered residential section it reaches is R611.6. The North Dakota State Building Code amendments to the same edition were read in full as well and amend no section of either chapter. So the extent of the barrier - which roof coverings it applies to, what it must consist of, and how far up the slope it must run - is governed by the adopted code's own provision at Section R905.1.2, unmodified. That ICC text is behind the ICC paywall; it is not restated here and this record does not rely on any third-party republication of it. A roofer needing the exact extent should read Section R905.1.2 in the code itself or ask Bismarck Building Inspections.
City of Casselton, North Dakota - Building Permits (City of Casselton, North Dakota)
Casselton's own Table 301.2(1), amending the 2021 International Residential Code's Section 301.2, carries an affirmative Yes in the column headed "Ice Barrier Underlayment Required" - see wind_design_criteria for the full table, read from the City's own rendered ordinance page. That column is the switch Section R905.1.2 of the International Residential Code uses to turn on the ice-barrier requirement for a jurisdiction, so an ice barrier is required in Casselton by the City's own determination rather than by inference from climate data. Ordinance No. 329's amendment list for the 2021 IRC, read in full, touches Chapters 1 through 6, then 11, 14, 15, 20, 21, 24 and 44 - it does not reach Chapter 9, Roof Assemblies, where R905.1.2 sits, so no local variation on the extent of the underlayment has been found to reconcile against the base rule. The North Dakota amendments to the 2021 IRC, published in the state's own 2023 North Dakota State Building Code Book (effective January 1, 2023, amendments approved September 7, 2022) and read in full, likewise stop at Chapter 6 before resuming at Chapter 11, so the state has not touched it either. This record has not been able to open the base 2021 IRC text itself to state the exact run-up distance and steep-slope increase - see roof_layer_limit - so confirm the extent required with the Building Department or Midwest Inspection Services (701-532-1078). The same design-criteria table gives a winter design temperature of -18 degrees and an air freezing index of 4000, so an ice-dam detail is worth the extra material here regardless.
City of Dickinson, North Dakota - Department of Building Inspection (City of Dickinson, North Dakota)
Ice barrier underlayment is required in Dickinson, and the requirement is the City's own answer rather than a state default or an assumption about the climate. Dickinson fills in Table R301.2(1) of the International Residential Code itself, inside City Code Section 8-11, and its entry in the column for ice barrier underlayment is "Yes". WHY THAT COLUMN IS THE OPERATIVE ONE. The City's table carries the code's own footnote for that column, printed as footnote h: "In accordance with Sections R905.2.7.1, R905.4.3.1, R905.5.3.1, R905.6.3.1, R905.7.3.1 and R905.8.3.1, where there has been a history of local damage from the effects of ice damming, the jurisdiction shall fill in this part of the table with 'Yes.' Otherwise, the jurisdiction shall fill in this part of the table with 'No.'" Dickinson has answered "Yes", which switches on the ice barrier provisions in the residential code's roof-assemblies chapter for asphalt shingles and for the other covering types those sections name. WHAT IS NOT SETTLED HERE. The City states the trigger, not the installation detail. How far up the slope the barrier must run, and what materials satisfy it, come from the adopted edition of the residential code rather than from any Dickinson amendment, because the City has made no amendment to that chapter. The City's related design figures are a winter design temperature of minus 10 degrees, a ground snow load of 30 and a severe weathering classification. Confirm the required extent with the Department of Building Inspection when the permit is pulled.
City of Fargo, North Dakota - Inspections Department (City of Fargo, North Dakota)
Sourced from Fargo's own local amendment to the International Residential Code, not inferred from climate. Fargo Municipal Code Section 21.1-0102 amends Table R301.2 (Climatic and Geographic Design Criteria), and its printed "Ice Barrier Underlayment Required" column reads "Yes" for Fargo. The amended table does not itself restate the extent of the ice barrier (that is Section R905.1.2 of the International Residential Code, which Fargo's amendment ordinance does not touch), so the required distance the barrier must extend up the roof slope is governed by the unamended 2024 IRC text rather than by a Fargo-specific rule.
City of Horace, North Dakota - Building Permits and Inspections (City of Horace, North Dakota)
Horace has answered the trigger question itself rather than leaving it to the base code. City of Horace Ordinances Section 5-0102(2) revises "IRC - Table R301.2(1) Climactic and Geographic Design Criteria" and prints a completed table in which the column headed "Iced Barrier Underlayment Required" carries the entry Yes. That column is the switch the residential code uses to turn its ice-barrier provision on for a jurisdiction, so an ice barrier is required in Horace by the City's own determination and not by inference from the climate. THE EXTENT CAN NOW BE STATED, because it is identical under either edition Horace could be enforcing. Section R905.1.2 of the International Residential Code - read at Section R905.1.2 in both the 2021 edition (the edition Horace's neighbouring Grand Forks has codified) and the 2024 edition (the edition the North Dakota State Building Code now runs on) - requires the barrier to "consist of not fewer than two layers of underlayment cemented together, or a self-adhering polymer-modified bitumen sheet ... in place of normal underlayment," extending "from the lowest edges of all roof surfaces to a point not less than 24 inches inside the exterior wall line of the building," with the run-up increased to "not less than 36 inches measured along the roof slope from the eave edge of the building" wherever the roof slope is 8 units vertical in 12 units horizontal or steeper. Chapter 5-01 of the City of Horace Ordinances was read in full, Sections 5-0101 through 5-0105, and makes no other amendment touching roof coverings, so there is no local variation on that extent to reconcile, and the North Dakota amendments to the 2024 International Residential Code were also read in full - thirty numbered section amendments running from Chapter 1 through a Chapter 21 hydronic-piping item - with none reaching the roof-assemblies chapter. Because Section 5-0101 adopts the North Dakota State Building Code without naming an edition, confirm with the Building Administrator which edition your permit is written to, but expect the 24-inch (36-inch on steeper slopes) run-up either way. The same design-criteria table gives the winter design temperature as -18 degrees and the air freezing index as 4000 - this is a jurisdiction where an ice-dam detail earns its keep.
City of Mandan, North Dakota - Building Inspection Department (City of Mandan, North Dakota)
Sourced from the City of Mandan's own published climatic and geographic design criteria, not inferred from the climate. Mandan fills in the residential code table of climatic and geographic design criteria on its Building and Design Criteria page, and the "Ice Barrier Underlayment Required" line reads "YES". The City does not restate how far up the slope the barrier must run, and neither Mandan Municipal Code Chapter 111 nor the North Dakota amendment set touches the residential roofing chapter, so the extent of the barrier is governed by the unamended base residential code rather than by any Mandan specific rule. Plan on an ice barrier on every re-roof in Mandan and take the extent from the edition of the residential code the Building Inspection Department confirms is in force for your permit.
City of Tioga, North Dakota - Building Department (City of Tioga, North Dakota)
Tioga requires an ice and water barrier on its own published statement, not on any assumption about the North Dakota climate. The City's Building Department page lists the basic required building inspections the City Building Inspector performs, and one of them is "Roof / Ice & Water Barrier". A city does not inspect a component it does not require, and Tioga puts that inspection in the same list as its footing, framing and insulation inspections. Plan the job so the barrier is in and visible when the inspector comes, and remember that inspection appointments must be made at least 24 hours in advance and that it is the permit holder who has to call. WHERE THE DETAIL COMES FROM. The City's complete codified ordinance book, the 1999 Revised Ordinances of Tioga (updated through 6 June 2024), was read in full, and its building-code chapter (Chapter Thirteen, Sections 13.0101-13.0102) contains no climatic design-criteria table and no local amendment of any kind - it is a floating adoption of the North Dakota State Building Code with nothing else added. So the extent of the barrier - how far up the slope from the eave it must run, and how it is lapped and sealed - comes from the adopted residential code rather than from any City amendment, and the City's own current adoption is the 2024 International Residential Code. That base text is Section R905.1.2 of the 2024 International Residential Code, which requires the ice barrier to "extend from the lowest edges of all roof surfaces to a point not less than 24 inches (610 mm) inside the exterior wall line of the building", and on roofs with a slope of 8 units vertical in 12 units horizontal or steeper to be "applied not less than 36 inches (914 mm) measured along the roof slope from the eave edge of the building"; it may be two layers of underlayment cemented together or a self-adhering polymer-modified bitumen sheet, and detached accessory structures without conditioned floor area are exempt. WHAT NOT TO ASSUME. The same list also shows a separate "Insulation / Frost-proofing" inspection, so the roof inspection is not a catch-all; and because the City says the nature and scope of the project determines which inspections are required, a small repair may not draw the same sequence as a full tear-off.
City of Watford City, North Dakota - Building Department (City of Watford City, North Dakota)
Ice barrier underlayment is required in Watford City, on the City's own published statement rather than on any assumption about the climate. The City's Building Codes and Design Criteria page lists its required design criteria for the adopted codes, and among them it answers the ice barrier underlayment item "Yes". The same list gives a winter design temperature of negative 21 degrees Fahrenheit and an air freezing index of 4,000, which is the kind of climate the ice barrier provisions exist for. THE CITY ALSO INSPECTS IT, WHICH IS THE PART THAT AFFECTS SEQUENCING. Watford City publishes the list of building inspections it performs, and "Roof/Ice & Water Barrier" is one of them by name. So on a job where that inspection is called for, the barrier has to be inspected before the covering goes over it, and inspections must be scheduled at least 24 hours in advance. Build the inspection into the schedule rather than treating it as a formality at the end. WHAT IS NOT SETTLED HERE. The City states the trigger, not the installation detail. How far up the slope the barrier must run, and which materials satisfy it, come from the adopted edition of the residential code, because Watford City has made no amendment to the roof-assemblies chapter. Confirm the required extent with the Building Department when the permit is pulled.
City of West Fargo, North Dakota - Building Inspection Division (City of West Fargo, North Dakota)
Sourced from West Fargo's own local amendment to the International Residential Code rather than inferred from climate. West Fargo City Ordinance Section 5-0702 amends Table R301.2 (Climatic and Geographic Design Criteria), and the column headed Ice Barrier Underlayment Required reads "yes" for West Fargo. The amended table does not itself restate how far the barrier must extend up the slope; West Fargo's amendment list touches no section of IRC Chapter 9, so the extent is governed by the unamended 2024 International Residential Code text rather than by any West Fargo-specific rule.
Ward County, North Dakota - Building Inspector (Ward County, North Dakota)
Sourced from Ward County's own published design criteria rather than inferred from the climate. The Ward County Building Permit Checklist, under "REQUIRED DESIGN CRITERIA," prints the line "Ice Barrier Underlayment Required - Yes". That is the County's fill-in of the climatic and geographic design criteria the residential code leaves to each jurisdiction, so an ice barrier is required on a Ward County re-roof. The County does not restate how far up the slope the barrier must run. Neither the Ward County Land Zoning Ordinance nor the North Dakota amendment set touches the residential code's roof-assembly chapter, so the extent of the barrier is governed by the unamended base residential code - take that extent from the edition the Building Inspector confirms is in force for your permit, currently the 2024 International Residential Code under the 2026 North Dakota State Building Code.
Ice barrier required — Ohio (107)
Ashtabula County - Building Department (Ashtabula County, Ohio)
SET BY STATE RULE. Table 301.2(1) of the Residential Code of Ohio (OAC 4101:8-3-01) marks ice barrier underlayment as required, and its footnote h states that "all jurisdictions in Ohio have a history of local damage from the effects of ice damming". RCO 905.1.2 then requires the ice barrier for asphalt shingles and the other listed coverings, consisting of "not fewer than two layers of underlayment cemented together, or a self-adhering polymer-modified bitumen sheet", extending from the lowest edges of all roof surfaces "to a point not less than 24 inches (610 mm) inside the exterior wall line of the building", and on slopes of 8 in 12 or steeper not less than 36 inches measured along the slope from the eave edge. The section's own exception covers "Detached accessory structures and roof assemblies terminating at a vertical wall over unconditioned floor areas". Ohio Rev. Code 3781.01(B) lets a city add regulations that do not conflict with the state code; this record did not read Ashtabula County's own ordinances.
City of Akron, Ohio - Building Permits and Inspections (City of Akron, Ohio)
SET BY STATE RULE -- required in Akron exactly as everywhere else in Ohio, because Ohio makes the ice-damming determination statewide by rule rather than leaving it to local option. RCO Table 301.2(1) pre-fills "Ice Barrier Underlayment Required" as "Yes" for the whole state, with footnote (h): "In accordance with Sections 905.1.2, 905.4.3.1, 905.5.3.1, 905.6.3.1, 905.7.3.1 and 905.8.3.1, all jurisdictions in Ohio have a history of local damage from the effects of ice damming." RCO Section 905.1.2 (Ice barriers) provides, verbatim: "In areas where there has been a history of ice forming along the eaves causing a backup of water as designated in Table 301.2(1), an ice barrier shall be installed for asphalt shingles, metal roof shingles, mineral-surfaced roll roofing, slate and slate-type shingles, wood shingles and wood shakes. The ice barrier shall consist of not fewer than two layers of underlayment cemented together, or a self-adhering polymer-modified bitumen sheet shall be used in place of normal underlayment and extend from the lowest edges of all roof surfaces to a point not less than 24 inches (610 mm) inside the exterior wall line of the building. The 24 inch measurement shall be along the slope of the roof from the point where the projected outside face of the wall intersects the roof deck. On roofs with slope equal to or greater than eight units vertical in 12 units horizontal (67-percent slope), the ice barrier shall also be applied not less than 36 inches measured along the roof slope from the eave edge of the building." Exception, verbatim: "Detached accessory structures and roof assemblies terminating at a vertical wall over unconditioned floor areas."

Table 301.2(1) of the Residential Code of Ohio (OAC 4101:8-3-01) marks ice barrier underlayment as required, and its footnote h states that "all jurisdictions in Ohio have a history of local damage from the effects of ice damming". RCO 905.1.2 then requires the ice barrier for asphalt shingles and the other listed coverings, consisting of "not fewer than two layers of underlayment cemented together, or a self-adhering polymer-modified bitumen sheet", extending from the lowest edges of all roof surfaces "to a point not less than 24 inches (610 mm) inside the exterior wall line of the building", and on slopes of 8 in 12 or steeper not less than 36 inches measured along the slope from the eave edge. The section's own exception covers "Detached accessory structures and roof assemblies terminating at a vertical wall over unconditioned floor areas". Ohio Rev. Code 3781.01(B) lets a city add regulations that do not conflict with the state code; this record did not read Canal Winchester's own ordinances.
City of Canton, Ohio - Building/Code Enforcement Division (City of Canton, Ohio)
SET BY STATE RULE -- applies identically in Canton as everywhere else in Ohio. RCO Table 301.2(1) pre-fills "Ice Barrier Underlayment Required" as "Yes" for the whole state, with footnote (h) reciting that "all jurisdictions in Ohio have a history of local damage from the effects of ice damming." RCO Section 905.1.2 (Ice barriers) then requires an ice barrier for asphalt shingles and other listed coverings, consisting of not fewer than two layers of cemented underlayment or a self-adhering polymer-modified bitumen sheet, extending not less than 24 inches inside the exterior wall line (36 inches on slopes of 8:12 or greater). Exception: "Detached accessory structures and roof assemblies terminating at a vertical wall over unconditioned floor areas."
City of Centerville - Building Inspection (City of Centerville, Ohio)
SET BY STATE RULE. Table 301.2(1) of the Residential Code of Ohio (OAC 4101:8-3-01) marks ice barrier underlayment as required, and its footnote h states that "all jurisdictions in Ohio have a history of local damage from the effects of ice damming". RCO 905.1.2 then requires the ice barrier for asphalt shingles and the other listed coverings, consisting of "not fewer than two layers of underlayment cemented together, or a self-adhering polymer-modified bitumen sheet", extending from the lowest edges of all roof surfaces "to a point not less than 24 inches (610 mm) inside the exterior wall line of the building", and on slopes of 8 in 12 or steeper not less than 36 inches measured along the slope from the eave edge. The section's own exception covers "Detached accessory structures and roof assemblies terminating at a vertical wall over unconditioned floor areas". Ohio Rev. Code 3781.01(B) lets a city add regulations that do not conflict with the state code; this record did not read Centerville's own ordinances.
City of Chillicothe - Building Department (City of Chillicothe, Ohio)
SET BY STATE RULE. Table 301.2(1) of the Residential Code of Ohio (OAC 4101:8-3-01) marks ice barrier underlayment as required, and its footnote h states that "all jurisdictions in Ohio have a history of local damage from the effects of ice damming". RCO 905.1.2 then requires the ice barrier for asphalt shingles and the other listed coverings, consisting of "not fewer than two layers of underlayment cemented together, or a self-adhering polymer-modified bitumen sheet", extending from the lowest edges of all roof surfaces "to a point not less than 24 inches (610 mm) inside the exterior wall line of the building", and on slopes of 8 in 12 or steeper not less than 36 inches measured along the slope from the eave edge. The section's own exception covers "Detached accessory structures and roof assemblies terminating at a vertical wall over unconditioned floor areas". Ohio Rev. Code 3781.01(B) lets a city add regulations that do not conflict with the state code; this record did not read Chillicothe's own ordinances.
City of Cincinnati, Ohio - Department of Buildings & Inspections (City of Cincinnati, Ohio)
SET BY STATE RULE - required in Cincinnati exactly as everywhere else in Ohio, because Ohio makes the ice-damming determination statewide by rule rather than leaving it to local option. RCO Table 301.2(1) pre-fills "Ice Barrier Underlayment Required" as "Yes" for the whole state, with footnote (h): "In accordance with Sections 905.1.2, 905.4.3.1, 905.5.3.1, 905.6.3.1, 905.7.3.1 and 905.8.3.1, all jurisdictions in Ohio have a history of local damage from the effects of ice damming." RCO Section 905.1.2 (Ice barriers) then provides, verbatim: "In areas where there has been a history of ice forming along the eaves causing a backup of water as designated in Table 301.2(1), an ice barrier shall be installed for asphalt shingles, metal roof shingles, mineral-surfaced roll roofing, slate and slate-type shingles, wood shingles and wood shakes. The ice barrier shall consist of not fewer than two layers of underlayment cemented together, or a self-adhering polymer-modified bitumen sheet shall be used in place of normal underlayment and extend from the lowest edges of all roof surfaces to a point not less than 24 inches (610 mm) inside the exterior wall line of the building. The 24 inch measurement shall be along the slope of the roof from the point where the projected outside face of the wall intersects the roof deck. On roofs with slope equal to or greater than eight units vertical in 12 units horizontal (67-percent slope), the ice barrier shall also be applied not less than 36 inches measured along the roof slope from the eave edge of the building." The final two sentences are Ohio-specific additions beyond the base 2018 IRC text. Exception: "Detached accessory structures and roof assemblies terminating at a vertical wall over unconditioned floor areas" (the italicised clause is also an Ohio addition).
City of Cleveland Heights, Ohio - Division of Building (City of Cleveland Heights, Cuyahoga County, Ohio)
Required, and required everywhere in Ohio rather than in a mapped zone. Residential Code of Ohio section 905.1.2 conditions the ice barrier on a local history of ice damming "as designated in Table 301.2(1)", and the state's own Table 301.2(1) answers that designation for the whole state: the ICE BARRIER UNDERLAYMENT REQUIRED column reads "Yes", and note h to the table states that "all jurisdictions in Ohio have a history of local damage from the effects of ice damming." So there is no per city determination to look up. The assembly is specified in 905.1.2: the barrier "shall consist of not fewer than two layers of underlayment cemented together, or a self-adhering polymer-modified bitumen sheet shall be used in place of normal underlayment and extend from the lowest edges of all roof surfaces to a point not less than 24 inches (610 mm) inside the exterior wall line of the building." That 24 inches is measured along the slope from where the projected outside face of the wall meets the roof deck. On roofs of 8:12 or steeper the barrier "shall also be applied not less than 36 inches (914 mm) measured along the roof slope from the eave edge of the building." It applies to asphalt shingles, metal roof shingles, mineral surfaced roll roofing, slate and slate-type shingles, wood shingles and wood shakes. One exception travels with it: "Detached accessory structures and roof assemblies terminating at a vertical wall over unconditioned floor areas."
City of Cleveland, Ohio - Department of Building and Housing (City of Cleveland, Ohio)
SET BY STATE RULE -- applies identically in Cleveland as everywhere else in Ohio. RCO Table 301.2(1) (OAC 4101:8-3-01, effective 7/1/2019) pre-fills "Ice Barrier Underlayment Required" as "Yes" for the whole state, with footnote (h): "In accordance with Sections 905.1.2, 905.4.3.1, 905.5.3.1, 905.6.3.1, 905.7.3.1 and 905.8.3.1, all jurisdictions in Ohio have a history of local damage from the effects of ice damming." Ohio therefore invokes the IRC ice-damming trigger uniformly by rule rather than leaving it to local determination. RCO Section 905.1.2 (OAC 4101:8-9-01, effective 7/1/2019) reads verbatim: "In areas where there has been a history of ice forming along the eaves causing a backup of water as designated in Table 301.2(1), an ice barrier shall be installed for asphalt shingles, metal roof shingles, mineral-surfaced roll roofing, slate and slate-type shingles, wood shingles and wood shakes. The ice barrier shall consist of not fewer than two layers of underlayment cemented together, or a self-adhering polymer-modified bitumen sheet shall be used in place of normal underlayment and extend from the lowest edges of all roof surfaces to a point not less than 24 inches (610 mm) inside the exterior wall line of the building. The 24 inch measurement shall be along the slope of the roof from the point where the projected outside face of the wall intersects the roof deck. On roofs with slope equal to or greater than eight units vertical in 12 units horizontal (67-percent slope), the ice barrier shall also be applied not less than 36 inches measured along the roof slope from the eave edge of the building." The last two sentences are Ohio-specific additions beyond base 2018 IRC text. Exception, verbatim: "Detached accessory structures and roof assemblies terminating at a vertical wall over unconditioned floor areas."
City of Columbus, Ohio - Department of Building and Zoning Services (City of Columbus, Ohio)
SET BY STATE RULE -- applies identically in Columbus as everywhere else in Ohio. RCO Table 301.2(1) as printed in OAC 4101:8-3-01 pre-fills "Ice Barrier Underlayment Required" as "Yes" for the whole state rather than leaving it to local determination, and its footnote (h) explains why: "In accordance with Sections 905.1.2, 905.4.3.1, 905.5.3.1, 905.6.3.1, 905.7.3.1 and 905.8.3.1, all jurisdictions in Ohio have a history of local damage from the effects of ice damming." RCO Section 905.1.2 (OAC 4101:8-9-01) then requires: "an ice barrier shall be installed for asphalt shingles, metal roof shingles, mineral-surfaced roll roofing, slate and slate-type shingles, wood shingles and wood shakes. The ice barrier shall consist of not fewer than two layers of underlayment cemented together, or a self-adhering polymer-modified bitumen sheet shall be used in place of normal underlayment and extend from the lowest edges of all roof surfaces to a point not less than 24 inches (610 mm) inside the exterior wall line of the building." Ohio adds text beyond the base 2018 IRC: "The 24 inch measurement shall be along the slope of the roof from the point where the projected outside face of the wall intersects the roof deck. On roofs with slope equal to or greater than eight units vertical in 12 units horizontal (67-percent slope), the ice barrier shall also be applied not less than 36 inches measured along the roof slope from the eave edge of the building." Exception: "Detached accessory structures and roof assemblies terminating at a vertical wall over unconditioned floor areas" (the italicized portion is also an Ohio-specific addition).
City of Dayton, Ohio - Division of Building Inspection (City of Dayton, Ohio)
SET BY STATE RULE - required in Dayton exactly as everywhere else in Ohio, because Ohio makes the ice-damming determination statewide by rule rather than leaving it to local option. RCO Table 301.2(1) pre-fills "Ice Barrier Underlayment Required" as "Yes" for the whole state, with footnote (h) reciting that "all jurisdictions in Ohio have a history of local damage from the effects of ice damming." RCO Section 905.1.2 (Ice barriers) then requires an ice barrier for asphalt shingles and other listed coverings, consisting of not fewer than two layers of cemented underlayment or a self-adhering polymer-modified bitumen sheet, extending not less than 24 inches inside the exterior wall line (36 inches on slopes of 8:12 or greater). Exception: "Detached accessory structures and roof assemblies terminating at a vertical wall over unconditioned floor areas." Dayton's codified Chapter 153 names the 1999 Ohio Residential Code for One, Two, and Three Family Dwellings (153.01(A)(2), unamended since 2002); this note states the 2019 RCO, which the state rule applies to every one-, two- or three-family dwelling (RCO 101.2) and which the city's own building codes page says it enforces; the 1999 text was not obtained (see adopted_code).
City of Defiance - Building Inspection Division (City of Defiance, Ohio)
SET BY STATE RULE. Table 301.2(1) of the Residential Code of Ohio (OAC 4101:8-3-01) marks ice barrier underlayment as required, and its footnote h states that "all jurisdictions in Ohio have a history of local damage from the effects of ice damming". RCO 905.1.2 then requires the ice barrier for asphalt shingles and the other listed coverings, consisting of "not fewer than two layers of underlayment cemented together, or a self-adhering polymer-modified bitumen sheet", extending from the lowest edges of all roof surfaces "to a point not less than 24 inches (610 mm) inside the exterior wall line of the building", and on slopes of 8 in 12 or steeper not less than 36 inches measured along the slope from the eave edge. The section's own exception covers "Detached accessory structures and roof assemblies terminating at a vertical wall over unconditioned floor areas". Ohio Rev. Code 3781.01(B) lets a city add regulations that do not conflict with the state code; this record did not read Defiance's own ordinances.
City of Eastlake - Building Department (City of Eastlake, Ohio)
SET BY STATE RULE. Table 301.2(1) of the Residential Code of Ohio (OAC 4101:8-3-01) marks ice barrier underlayment as required, and its footnote h states that "all jurisdictions in Ohio have a history of local damage from the effects of ice damming". RCO 905.1.2 then requires the ice barrier for asphalt shingles and the other listed coverings, consisting of "not fewer than two layers of underlayment cemented together, or a self-adhering polymer-modified bitumen sheet", extending from the lowest edges of all roof surfaces "to a point not less than 24 inches (610 mm) inside the exterior wall line of the building", and on slopes of 8 in 12 or steeper not less than 36 inches measured along the slope from the eave edge. The section's own exception covers "Detached accessory structures and roof assemblies terminating at a vertical wall over unconditioned floor areas". Ohio Rev. Code 3781.01(B) lets a city add regulations that do not conflict with the state code; this record did not read Eastlake's own ordinances.
City of Elyria, Ohio - Building Department (City of Elyria, Ohio)
SET BY STATE RULE, confirmed from the state's own copies of both RCO instruments, each read in full. RCO Table 301.2(1) ("Climatic and Geographic Design Criteria," OAC 4101:8-3-01, effective 7/1/2019) pre-fills "Ice Barrier Underlayment Required" as "Yes" for the entire state, with footnote (h) reciting, verbatim: "In accordance with Sections 905.1.2, 905.4.3.1, 905.5.3.1, 905.6.3.1, 905.7.3.1 and 905.8.3.1, all jurisdictions in Ohio have a history of local damage from the effects of ice damming." RCO Section 905.1.2 (OAC 4101:8-9-01) requires the ice barrier to extend from the lowest roof edge to a point not less than 24 inches inside the exterior wall line (36 inches on slopes at or above 8:12), consisting of not fewer than two layers of cemented underlayment or a self-adhering polymer-modified bitumen sheet. No Elyria-specific ice-barrier statement was found in the city's own permit materials, and Elyria's full codified ordinances are not accessible online (see the note under adopted_code).
City of Euclid, Ohio - Department of Building and Housing (City of Euclid, Cuyahoga County, Ohio)
Required, and required across the whole state rather than in a mapped zone, which matters on a Lake Erie shoreline city. Residential Code of Ohio section 905.1.2 conditions the ice barrier on a local history of ice damming "as designated in Table 301.2(1)", and Ohio's own Table 301.2(1) makes that designation statewide: the ICE BARRIER UNDERLAYMENT REQUIRED column reads "Yes", and note h to the table states that "all jurisdictions in Ohio have a history of local damage from the effects of ice damming." There is therefore no per-city determination to look up. The barrier "shall consist of not fewer than two layers of underlayment cemented together, or a self-adhering polymer-modified bitumen sheet shall be used in place of normal underlayment and extend from the lowest edges of all roof surfaces to a point not less than 24 inches (610 mm) inside the exterior wall line of the building," measured along the slope from where the projected outside face of the wall meets the deck. On roofs of 8:12 or steeper it "shall also be applied not less than 36 inches (914 mm) measured along the roof slope from the eave edge." One exception travels with it: "Detached accessory structures and roof assemblies terminating at a vertical wall over unconditioned floor areas." It applies to asphalt shingles, metal roof shingles, mineral surfaced roll roofing, slate and slate-type shingles, wood shingles and wood shakes.

CITY-CONFIRMED, and consistent with the statewide RCO floor. The City of Hamilton's own "Roofing Permit (Existing Building)" application states, verbatim: "NOTICE: ALL ROOFING PERMITS REQUIRE INSPECTION APPROVAL! INSPECTION IS REQUIRED TO VERIFY THE ICE GUARD AND UNDERLAYMENT INSTALLATION AS WELL AS THE ROOF COMPLETION." The form does not itself state a coverage distance. Ohio's statewide floor (RCO Table 301.2(1), OAC 4101:8-3-01, effective 7/1/2019) pre-fills "Ice Barrier Underlayment Required" as "Yes" for the entire state, with RCO Section 905.1.2 (OAC 4101:8-9-01) requiring the ice barrier to extend from the lowest roof edge to a point not less than 24 inches inside the exterior wall line (36 inches on slopes at or above 8:12).

Springfield's own Residential Re-roofing Affidavit Application (page 2, "Residential Roofing Regulations," read in full) states, verbatim: "Per Table 301.2(1) ice barrier underlayment is required in the state of Ohio." Springfield's own "Current Adopted Ohio Building Codes" document (read in full) prints a Springfield-specific Design Criteria table with "Ice Shield Underlayment Req." listed as "Yes." This matches RCO Table 301.2(1) (OAC 4101:8-3-01, effective 7/1/2019, read in full), which pre-fills "Ice Barrier Underlayment Required" as "Yes" statewide, with RCO Section 905.1.2 requiring the ice barrier to extend from the lowest roof edge to a point not less than 24 inches inside the exterior wall line (36 inches on slopes at or above 8:12).

City of Strongsville, Ohio - Building Department (City of Strongsville, Cuyahoga County, Ohio)
Required, and required across the whole state rather than in a mapped zone. Residential Code of Ohio section 905.1.2 conditions the ice barrier on a local history of ice damming "as designated in Table 301.2(1)", and Ohio's own Table 301.2(1) makes that designation statewide: the ICE BARRIER UNDERLAYMENT REQUIRED column reads "Yes", and note h to the table states that "all jurisdictions in Ohio have a history of local damage from the effects of ice damming." There is therefore no per-city determination to look up. The barrier "shall consist of not fewer than two layers of underlayment cemented together, or a self-adhering polymer-modified bitumen sheet shall be used in place of normal underlayment and extend from the lowest edges of all roof surfaces to a point not less than 24 inches (610 mm) inside the exterior wall line of the building," measured along the slope from where the projected outside face of the wall meets the deck. On roofs of 8:12 or steeper it "shall also be applied not less than 36 inches (914 mm) measured along the roof slope from the eave edge." One exception travels with it: "Detached accessory structures and roof assemblies terminating at a vertical wall over unconditioned floor areas." It applies to asphalt shingles, metal roof shingles, mineral surfaced roll roofing, slate and slate-type shingles, wood shingles and wood shakes.
City of Toledo, Ohio - Division of Building Inspection (City of Toledo, Ohio)
SET BY STATE RULE -- required in Toledo exactly as everywhere else in Ohio, because Ohio makes the ice-damming determination statewide by rule rather than leaving it to local option. RCO Table 301.2(1) pre-fills "Ice Barrier Underlayment Required" as "Yes" for the whole state, with footnote (h): "In accordance with Sections 905.1.2, 905.4.3.1, 905.5.3.1, 905.6.3.1, 905.7.3.1 and 905.8.3.1, all jurisdictions in Ohio have a history of local damage from the effects of ice damming." RCO Section 905.1.2 (Ice barriers) provides, verbatim: "In areas where there has been a history of ice forming along the eaves causing a backup of water as designated in Table 301.2(1), an ice barrier shall be installed for asphalt shingles, metal roof shingles, mineral-surfaced roll roofing, slate and slate-type shingles, wood shingles and wood shakes. The ice barrier shall consist of not fewer than two layers of underlayment cemented together, or a self-adhering polymer-modified bitumen sheet shall be used in place of normal underlayment and extend from the lowest edges of all roof surfaces to a point not less than 24 inches (610 mm) inside the exterior wall line of the building. The 24 inch measurement shall be along the slope of the roof from the point where the projected outside face of the wall intersects the roof deck. On roofs with slope equal to or greater than eight units vertical in 12 units horizontal (67-percent slope), the ice barrier shall also be applied not less than 36 inches measured along the roof slope from the eave edge of the building." Exception, verbatim: "Detached accessory structures and roof assemblies terminating at a vertical wall over unconditioned floor areas." Toledo's own (stale, pre-2019-RCO) Construction Procedures handout independently prints a Toledo-specific reading of the same table row confirming "Ice Shield Underlayment Required: Yes" for Toledo/Lucas County, consistent with the statewide rule.

Exception, verbatim: "Detached accessory structures and roof assemblies terminating at a vertical wall over unconditioned floor areas." Independently corroborated by Mahoning County's own Appendix III (its reproduction of Table 301.2(1) in the Mahoning County Building Regulations), which likewise lists "Ice Shield Underlayment Required -- Yes."
City of Zanesville - Building & Code Enforcement (City of Zanesville, Ohio)
SET BY STATE RULE. Table 301.2(1) of the Residential Code of Ohio (OAC 4101:8-3-01) marks ice barrier underlayment as required, and its footnote h states that "all jurisdictions in Ohio have a history of local damage from the effects of ice damming". RCO 905.1.2 then requires the ice barrier for asphalt shingles and the other listed coverings, consisting of "not fewer than two layers of underlayment cemented together, or a self-adhering polymer-modified bitumen sheet", extending from the lowest edges of all roof surfaces "to a point not less than 24 inches (610 mm) inside the exterior wall line of the building", and on slopes of 8 in 12 or steeper not less than 36 inches measured along the slope from the eave edge. The section's own exception covers "Detached accessory structures and roof assemblies terminating at a vertical wall over unconditioned floor areas". Ohio Rev. Code 3781.01(B) lets a city add regulations that do not conflict with the state code; this record did not read Zanesville's own ordinances.
Hamilton County, Ohio - Buildings and Inspections (Hamilton County, Ohio)
COUNTY-CONFIRMED, and independently required at the state level. Hamilton County's own Roofing Data Sheet, Note 3, states verbatim: "Ice barriers are required from the lowest edges of all roof surfaces upward to a point not less than 24-inches (measured horizontally) inside the front face of the exterior building wall." This matches the statewide RCO floor: RCO Table 301.2(1) (OAC 4101:8-3-01, effective 7/1/2019) pre-fills "Ice Barrier Underlayment Required" as "Yes" statewide, and RCO Section 905.1.2 requires the ice barrier to extend from the lowest roof edge to a point not less than 24 inches inside the exterior wall line (36 inches on slopes at or above 8:12).
Licking County - Building Code Department (Licking County, Ohio)
SET BY STATE RULE. Table 301.2(1) of the Residential Code of Ohio (OAC 4101:8-3-01) marks ice barrier underlayment as required, and its footnote h states that "all jurisdictions in Ohio have a history of local damage from the effects of ice damming". RCO 905.1.2 then requires the ice barrier for asphalt shingles and the other listed coverings, consisting of "not fewer than two layers of underlayment cemented together, or a self-adhering polymer-modified bitumen sheet", extending from the lowest edges of all roof surfaces "to a point not less than 24 inches (610 mm) inside the exterior wall line of the building", and on slopes of 8 in 12 or steeper not less than 36 inches measured along the slope from the eave edge. The section's own exception covers "Detached accessory structures and roof assemblies terminating at a vertical wall over unconditioned floor areas". Ohio Rev. Code 3781.01(B) lets a city add regulations that do not conflict with the state code; this record did not read Licking County's own ordinances.
Lucas County, Ohio - Building Regulations Department (Lucas County, Ohio)
Required, and required across the whole state rather than in a mapped zone. Residential Code of Ohio section 905.1.2 conditions the ice barrier on a local history of ice damming "as designated in Table 301.2(1)", and Ohio's own Table 301.2(1) makes that designation statewide: the ICE BARRIER UNDERLAYMENT REQUIRED column reads "Yes", and note h to the table states that "all jurisdictions in Ohio have a history of local damage from the effects of ice damming." There is therefore no per-city determination to look up. The barrier "shall consist of not fewer than two layers of underlayment cemented together, or a self-adhering polymer-modified bitumen sheet shall be used in place of normal underlayment and extend from the lowest edges of all roof surfaces to a point not less than 24 inches (610 mm) inside the exterior wall line of the building," measured along the slope from where the projected outside face of the wall meets the deck. On roofs of 8:12 or steeper it "shall also be applied not less than 36 inches (914 mm) measured along the roof slope from the eave edge." One exception travels with it: "Detached accessory structures and roof assemblies terminating at a vertical wall over unconditioned floor areas." It applies to asphalt shingles, metal roof shingles, mineral surfaced roll roofing, slate and slate-type shingles, wood shingles and wood shakes.
Medina County - Building Department (Medina County, Ohio)
SET BY STATE RULE. Table 301.2(1) of the Residential Code of Ohio (OAC 4101:8-3-01) marks ice barrier underlayment as required, and its footnote h states that "all jurisdictions in Ohio have a history of local damage from the effects of ice damming". RCO 905.1.2 then requires the ice barrier for asphalt shingles and the other listed coverings, consisting of "not fewer than two layers of underlayment cemented together, or a self-adhering polymer-modified bitumen sheet", extending from the lowest edges of all roof surfaces "to a point not less than 24 inches (610 mm) inside the exterior wall line of the building", and on slopes of 8 in 12 or steeper not less than 36 inches measured along the slope from the eave edge. The section's own exception covers "Detached accessory structures and roof assemblies terminating at a vertical wall over unconditioned floor areas". Ohio Rev. Code 3781.01(B) lets a city add regulations that do not conflict with the state code; this record did not read Medina County's own ordinances.
Miami County - Department of Development, Building Regulations (Miami County, Ohio)
SET BY STATE RULE. Table 301.2(1) of the Residential Code of Ohio (OAC 4101:8-3-01) marks ice barrier underlayment as required, and its footnote h states that "all jurisdictions in Ohio have a history of local damage from the effects of ice damming". RCO 905.1.2 then requires the ice barrier for asphalt shingles and the other listed coverings, consisting of "not fewer than two layers of underlayment cemented together, or a self-adhering polymer-modified bitumen sheet", extending from the lowest edges of all roof surfaces "to a point not less than 24 inches (610 mm) inside the exterior wall line of the building", and on slopes of 8 in 12 or steeper not less than 36 inches measured along the slope from the eave edge. The section's own exception covers "Detached accessory structures and roof assemblies terminating at a vertical wall over unconditioned floor areas". Ohio Rev. Code 3781.01(B) lets a city add regulations that do not conflict with the state code; this record did not read Miami County's own ordinances.
Pickaway County - Building Department (Pickaway County, Ohio)
SET BY STATE RULE. Table 301.2(1) of the Residential Code of Ohio (OAC 4101:8-3-01) marks ice barrier underlayment as required, and its footnote h states that "all jurisdictions in Ohio have a history of local damage from the effects of ice damming". RCO 905.1.2 then requires the ice barrier for asphalt shingles and the other listed coverings, consisting of "not fewer than two layers of underlayment cemented together, or a self-adhering polymer-modified bitumen sheet", extending from the lowest edges of all roof surfaces "to a point not less than 24 inches (610 mm) inside the exterior wall line of the building", and on slopes of 8 in 12 or steeper not less than 36 inches measured along the slope from the eave edge. The section's own exception covers "Detached accessory structures and roof assemblies terminating at a vertical wall over unconditioned floor areas". Ohio Rev. Code 3781.01(B) lets a city add regulations that do not conflict with the state code; this record did not read Pickaway County's own ordinances.
Summit County, Ohio - Division of Building Standards (Summit County, Ohio)
SET BY STATE RULE, and required across the whole of Ohio by the code's own text. RCO Table 301.2(1) "Climatic and Geographic Design Criteria" (OAC 4101:8-3-01, effective July 1, 2019), read from the state's own copy, pre-fills "ICE BARRIER UNDERLAYMENT REQUIRED" as "Yes" for the entire state rather than leaving it for each jurisdiction to complete, and its note h recites that "In accordance with Sections 905.1.2, 905.4.3.1, 905.5.3.1, 905.6.3.1, 905.7.3.1 and 905.8.3.1, all jurisdictions in Ohio have a history of local damage from the effects of ice damming." RCO Section 905.1.2 then sets the detail: the ice barrier is required for asphalt shingles among other coverings, "shall consist of not fewer than two layers of underlayment cemented together, or a self-adhering polymer-modified bitumen sheet shall be used in place of normal underlayment and extend from the lowest edges of all roof surfaces to a point not less than 24 inches (610 mm) inside the exterior wall line of the building," measured along the slope from where the projected outside face of the wall meets the deck, and on roofs of eight units vertical in 12 units horizontal or steeper it must also run not less than 36 inches measured along the slope from the eave edge. Section 905.1.2 carries one exception, worth knowing before quoting a detached garage: "Detached accessory structures and roof assemblies terminating at a vertical wall over unconditioned floor areas." Ohio Rev. Code 3781.01(B) lets a county add non-conflicting local regulations, so the County's own Building Code was read to see whether it expands this: Part Thirteen of the Codified Ordinances of the County of Summit, as amended in full by County Ordinance No. 2024-047 (enacted March 4, 2024, effective March 5, 2024) and further amended by County Ordinance No. 2025-259 (enacted September 8, 2025), was read across all twelve of its chapters and states no ice barrier or underlayment provision. The state requirement stands unmodified in Summit County.
Union County - Building Department (Union County, Ohio)
SET BY STATE RULE. Table 301.2(1) of the Residential Code of Ohio (OAC 4101:8-3-01) marks ice barrier underlayment as required, and its footnote h states that "all jurisdictions in Ohio have a history of local damage from the effects of ice damming". RCO 905.1.2 then requires the ice barrier for asphalt shingles and the other listed coverings, consisting of "not fewer than two layers of underlayment cemented together, or a self-adhering polymer-modified bitumen sheet", extending from the lowest edges of all roof surfaces "to a point not less than 24 inches (610 mm) inside the exterior wall line of the building", and on slopes of 8 in 12 or steeper not less than 36 inches measured along the slope from the eave edge. The section's own exception covers "Detached accessory structures and roof assemblies terminating at a vertical wall over unconditioned floor areas". Ohio Rev. Code 3781.01(B) lets a city add regulations that do not conflict with the state code; this record did not read Union County's own ordinances.
Ice barrier required — Oklahoma (12)
City of Broken Arrow - Community Permitting and Licensing Division (City of Broken Arrow, Oklahoma)
A 36-inch-wide ice barrier IS required in all valleys ("installed in all valleys, run the length of the valley, and centered on the valley") and at all changes in roof pitch where the lower roof has a lower pitch than the upper roof -- unconditional requirements added to IRC Sec. 905.1.2 by the OUBCC 2018 IRC Permanent Rule, "the statewide minimum code for residential building construction... pursuant to 59 O.S. Sec. 1000.23," which "may only be amended or altered by other jurisdictions pursuant to Oklahoma law"; the city's own amendment ordinance, read in full, does not alter Sec. 905.1.2. At the EAVES, the city's own amended Table R301.2(1) answers the eave ice-damming trigger "Ice Barrier Underlayment Required = No" (Sec. 6-37(g), Ord. No. 3826, 4-16-2024). Net effect: ice barrier required in valleys and at pitch changes everywhere in the city; not required at eaves.
City of Edmond Department of Building & Safety (City of Edmond, Oklahoma)
"Ice and water shield is currently only required at valleys and at roof pitch changes where the lower pitch is less than the upper pitch." (City of Edmond Department of Building & Safety roofing FAQ). Not required roof-wide -- only at valleys and pitch changes.
City of Jenks - Building Inspections Department (City of Jenks, Oklahoma)
A 36-inch-wide ice barrier IS required in all valleys ("installed in all valleys, run the length of the valley, and centered on the valley") and at all changes in roof pitch where the lower roof has a lower pitch than the upper roof -- unconditional requirements added to IRC Sec. 905.1.2 by the OUBCC 2018 IRC Permanent Rule, "the statewide minimum code for residential building construction... pursuant to 59 O.S. Sec. 1000.23." Jenks Sec. 4-1-1 through 4-1-8 contains no local amendment touching Sec. 905.1.2 or any other roofing provision, and no local climate-design table addressing the eave ice-damming trigger was found, so only the unconditional valley and pitch-change requirement is stated here.
City of Lawton License & Permits Division and Inspection Services (City of Lawton, Oklahoma)
NOT AT THE EAVES, BUT IN VALLEYS AND AT LOW-SIDE PITCH CHANGES. Lawton's Section 6-1-1-105(C) amends Table R301.2(1) to read "Ice barrier underlayment required: No," and the state's rewritten 905.1.2 ties the eave ice barrier (its paragraph (A)) to areas "designated in Table R301.2(1)." The same rule, OAC 748:20-6-14 item (1), adds two paragraphs that as printed make no reference to that table: "(B) A 36-inch wide (914 mm) ice barrier shall be installed in all valleys, run the length of the valley, and centered on the valley," and "(C) A 36-inch wide (914 mm) ice barrier shall be installed at all change in roof pitch in which the lower roof has a lower pitch than the upper roof."
City of Midwest City - Permits & Building Inspections Division (City of Midwest City, Oklahoma)
A 36-inch-wide ice barrier IS required in all valleys ("installed in all valleys, run the length of the valley, and centered on the valley") and at all changes in roof pitch where the lower roof has a lower pitch than the upper roof -- unconditional requirements added to IRC Sec. 905.1.2 by the OUBCC 2018 IRC Permanent Rule, "the statewide minimum code for residential building construction... pursuant to 59 O.S. Sec. 1000.23," which "may only be amended or altered by other jurisdictions pursuant to Oklahoma law." Midwest City Code of Ordinances Sec. 9-5(b) adopts the 2018 International Residential Code, and Sec. 9-7 ("Code amended--International Residential Code") (Ord. No. 3560, Sec. 1, 4-23-24; Ord. No. 3590, Sec. 1, 3-25-25; Ord. No. 3591, Sec. 2, 3-25-25), read in full, amends only administrative/permit provisions (102.4.1, 104.1, 104.2, 105.10, 107.3.1, 108.2, 109.4, 110.0, 112.1) -- it does not alter Sec. 905.1.2, so the statewide amendment stands as the city's operative law. No local Table R301.2(1) exists for Midwest City, so the eave/ice-damming trigger cannot be stated here -- only the unconditional valley and pitch-change requirement is published.
City of Moore - Building Permits & Inspections (Community Development Department) (City of Moore, Oklahoma)
Required -- and, unusually among Oklahoma jurisdictions, set by the City of Moore's OWN local amendments rather than by the state minimum. Moore's own amended IRC Table R301.2(1) (Municipal Code Sec. 5-204, table amendment codified as an image reproduction of Ord. No. 1039.23, 12-18-2023) answers the "Ice Barrier Underlayment Required" cell "Yes" (alongside: ground snow load 10 lb/ft2, wind design speed 135 mph, topographic/special-wind-region/windborne-debris all "No," seismic design category C, winter design temp 13 F, air freezing index 300, mean annual temp 60.9 F). Separately and more specifically, Moore's Sec. 5-204 directly rewrites IRC R905.1.2 itself (not merely silence/adopt-unamended): "R905.1.2 Ice barriers. In the roof valleys an ice barrier shall be installed for asphalt shingles, metal roof shingles, mineral surface roll roofing, s[l]ate and slate-type shingles, wood shingles and wood shakes. The ice barrier shall consist of not fewer than two layers of underlayment cemented together, or a self-adhering polymer modified bitumen sheet shall be used in place of normal underlayment and extend from the lowest edge of the roof surface. Exception: Detached accessory structures not containing conditioned floor area." That local text sets the valley trigger and specifies the underlayment method (two cemented layers, or a self-adhering membrane) but does not separately restate a roof-pitch-change trigger. Oklahoma's OUBCC 2018 IRC Permanent Rule -- the statewide minimum code Moore's Sec. 5-201/5-204 explicitly adopts "as amended and modified by the Oklahoma uniform building code commission pursuant to 59 O.S. Sec. 1000.23" -- additionally and unconditionally requires a 36-inch-wide ice barrier "at all change in roof pitch in which the lower roof has a lower pitch than the upper roof," a trigger Moore's own local amendment neither restates nor contradicts. Net effect in Moore: ice barrier required at eaves (per the city's own Table R301.2(1) "Yes"), in all roof valleys (per the city's own R905.1.2 text and method), and at pitch changes (per the state minimum, which Moore's own amendment does not address).
City of Mustang - Community Development Department (City of Mustang, Oklahoma)
A 36-inch-wide ice barrier IS required in all valleys ("installed in all valleys, run the length of the valley, and centered on the valley") and at all changes in roof pitch where the lower roof has a lower pitch than the upper roof -- unconditional requirements added to IRC Sec. 905.1.2 by the OUBCC 2018 IRC Permanent Rule, "the statewide minimum code for residential building construction... pursuant to 59 O.S. Sec. 1000.23," which "may only be amended or altered by other jurisdictions pursuant to Oklahoma law"; the city's own amendment ordinance, read in full, does not alter Sec. 905.1.2. At the EAVES, the city's own Ordinance No. 1269 (Sec. 18-33.B item 18, 8-2-2022) fills the same table cell "ice barrier underlayment required - no". Net effect: ice barrier required in valleys and at pitch changes everywhere in the city; not required at eaves.
City of Norman Development Services Division (City of Norman, Oklahoma)
"Does the code obligate Ice Barrier Underlayment? In most areas NO. But by state amendment a 36" wide strip is required to be installed in valleys and at roof pitch changes. (R905.1.2 with OUBCC Amendment)" (City of Norman "Common Questions for Roofing with Asphalt Shingles," Development Services Division / Building Permits and Inspections). Not required roof-wide -- only at valleys and roof pitch changes.
City of Oklahoma City - Development Services Department (City of Oklahoma City, Oklahoma)
A 36-inch-wide ice barrier IS required in all valleys ("installed in all valleys, run the length of the valley, and centered on the valley") and at all changes in roof pitch where the lower roof has a lower pitch than the upper roof -- unconditional requirements added to IRC Sec. 905.1.2 by the OUBCC 2018 IRC Permanent Rule, "the statewide minimum code for residential building construction... pursuant to 59 O.S. Sec. 1000.23," which "may only be amended or altered by other jurisdictions pursuant to Oklahoma law." At the EAVES, the City's own Re-Roofing Permit Requirements checklist answers the eave ice-damming trigger directly: "Q7. Are ice barriers required? No." (effective 7/28/25), consistent with the City's own Table R301.2(1), which fills "Ice Barrier Underlayment Required - No." Net effect: ice barrier required in valleys and at pitch changes everywhere in the city; not required at eaves. The same Sec. 905.1.2 text appears word-for-word in the City's own "2018 IRC Amendments, State Amendments Included" document.
City of Tulsa Development Services Department - Permit Center (City of Tulsa, Oklahoma)
Tulsa Code of Ordinances Title 51, Chapter 2, Section 201, Section 905.1.2 Ice barriers (locally amended): base trigger is "In areas where there has been a history of ice forming along the eaves causing a backup of water as designated in Table R301.2(1), an ice barrier shall be installed for asphalt shingles ... extend from the lowest edges of all roof surfaces to a point not less than 24 inches (610 mm) inside the exterior wall line of the building," plus two Tulsa-added unconditional triggers: "(B) A 36-inch wide (914 mm) ice barrier shall be installed in all valleys, run the length of the valley, and centered on the valley," and "(C) A 36-inch wide (914 mm) ice barrier shall be installed at all change in roof pitch in which the lower roof has a lower pitch than the upper roof. The ice barrier is run the length of the change in pitch and cemented on the change in pitch."
City of Yukon - Development Services (City of Yukon, Oklahoma)
City of Yukon Ordinance No. 1414 (adopted Aug. 18, 2020), Sec. 204-138, amends the adopted 2015 International Residential Code Table R301.2(1) "Climatic and Geographic Design Criteria" for the City of Yukon to read "Ice barrier underlayment required - Yes," alongside the table's Ground Snow Load, Wind Speed, and other city-specific design criteria entries.
Oklahoma County Planning Commission (Oklahoma County, Oklahoma)
A 36-inch-wide ice barrier IS required in all valleys ("installed in all valleys, run the length of the valley, and centered on the valley") and at all changes in roof pitch where the lower roof has a lower pitch than the upper roof -- unconditional requirements added to IRC Sec. 905.1.2 by the OUBCC 2018 IRC Permanent Rule, "the statewide minimum code for residential building construction... pursuant to 59 O.S. Sec. 1000.23." Resolution No. 2024-5421 (eff. 1-1-2025), which adopts the 2018 IRC "as modified by the OUBCC with the 2022 Oklahoma Amendments" for unincorporated Oklahoma County, read in full, does not touch any Chapter 9 Roof Assemblies provision, including Sec. 905.1.2. No local climate-design table stating whether an ice barrier is required at the EAVES was found for unincorporated Oklahoma County, so the eave question is left open here; only the unconditional valley and pitch-change requirement is stated.
Ice barrier required — Other (11)
Butler County, Ohio - Department of Development, Building and Zoning (Unincorporated Butler County, Ohio. The County's Building and Zoning staff is responsible for enforcing the building code, electrical code and zoning regulations "for the unincorporated areas of Butler County," so work inside an incorporated city or village is not this authority's. Its own inspection schedule names the townships it serves: Hanover, Morgan, Reily and Ross; College Corner, Madison, Milford, Oxford, St. Clair and Wayne; and Fairfield, Lemon, Liberty, Trenton and West Chester, which get inspections every day rather than on set days.)
Required, and required across the whole state rather than in a mapped zone. Residential Code of Ohio section 905.1.2 conditions the ice barrier on a local history of ice damming "as designated in Table 301.2(1)", and Ohio's own Table 301.2(1) makes that designation statewide: the ICE BARRIER UNDERLAYMENT REQUIRED column reads "Yes", and note h to the table states that "all jurisdictions in Ohio have a history of local damage from the effects of ice damming." There is therefore no per-city determination to look up. The barrier "shall consist of not fewer than two layers of underlayment cemented together, or a self-adhering polymer-modified bitumen sheet shall be used in place of normal underlayment and extend from the lowest edges of all roof surfaces to a point not less than 24 inches (610 mm) inside the exterior wall line of the building," measured along the slope from where the projected outside face of the wall meets the deck. On roofs of 8:12 or steeper it "shall also be applied not less than 36 inches (914 mm) measured along the roof slope from the eave edge." One exception travels with it: "Detached accessory structures and roof assemblies terminating at a vertical wall over unconditioned floor areas." It applies to asphalt shingles, metal roof shingles, mineral surfaced roll roofing, slate and slate-type shingles, wood shingles and wood shakes.
City of Dublin, Ohio - Division of Building Standards (City of Dublin, Ohio. Dublin straddles three counties — Franklin, Delaware and Union — which matters for tax but not for code, since the Residential Code of Ohio is a statewide rule.)
Required, and required across the whole state rather than in a mapped zone. Residential Code of Ohio section 905.1.2 conditions the ice barrier on a local history of ice damming "as designated in Table 301.2(1)", and Ohio's own Table 301.2(1) makes that designation statewide: the ICE BARRIER UNDERLAYMENT REQUIRED column reads "Yes", and note h to the table states that "all jurisdictions in Ohio have a history of local damage from the effects of ice damming." There is therefore no per-city determination to look up. The barrier "shall consist of not fewer than two layers of underlayment cemented together, or a self-adhering polymer-modified bitumen sheet shall be used in place of normal underlayment and extend from the lowest edges of all roof surfaces to a point not less than 24 inches (610 mm) inside the exterior wall line of the building," measured along the slope from where the projected outside face of the wall meets the deck. On roofs of 8:12 or steeper it "shall also be applied not less than 36 inches (914 mm) measured along the roof slope from the eave edge." One exception travels with it: "Detached accessory structures and roof assemblies terminating at a vertical wall over unconditioned floor areas." It applies to asphalt shingles, metal roof shingles, mineral surfaced roll roofing, slate and slate-type shingles, wood shingles and wood shakes.
City of Middletown, Ohio - Building Inspection Division (City of Middletown, Ohio. Middletown straddles Butler and Warren counties, which matters for sales tax — the two counties are at different rates and one of them changes on 2026-10-01 — but not for code, since the Residential Code of Ohio is a statewide rule.)
Required, and required across the whole state rather than in a mapped zone. Residential Code of Ohio section 905.1.2 conditions the ice barrier on a local history of ice damming "as designated in Table 301.2(1)", and Ohio's own Table 301.2(1) makes that designation statewide: the ICE BARRIER UNDERLAYMENT REQUIRED column reads "Yes", and note h to the table states that "all jurisdictions in Ohio have a history of local damage from the effects of ice damming." There is therefore no per-city determination to look up. The barrier "shall consist of not fewer than two layers of underlayment cemented together, or a self-adhering polymer-modified bitumen sheet shall be used in place of normal underlayment and extend from the lowest edges of all roof surfaces to a point not less than 24 inches (610 mm) inside the exterior wall line of the building," measured along the slope from where the projected outside face of the wall meets the deck. On roofs of 8:12 or steeper it "shall also be applied not less than 36 inches (914 mm) measured along the roof slope from the eave edge." One exception travels with it: "Detached accessory structures and roof assemblies terminating at a vertical wall over unconditioned floor areas." It applies to asphalt shingles, metal roof shingles, mineral surfaced roll roofing, slate and slate-type shingles, wood shingles and wood shakes.
City of Spearfish, South Dakota - Building Services Division (City of Spearfish, Lawrence County, South Dakota, together with the Lawrence County Joint Powers Area outside the city limits for which the City's Building Services Division issues building permits. Where an address sits relative to the city limit still matters for tax even though it does not change which desk issues the permit: the municipal sales and use tax applies inside the city and not in the surrounding unincorporated county.)
Required, and stated twice in first-party sources that agree exactly. The Climatic and Geographic Design Criteria table published inside Section 150.016(A) of the codified ordinance, headed "Climatic and Geographic Design Criteria / City of Spearfish, SD," carries the row "Ice shield under-underlayment required Yes" - the doubled "under-" is verbatim in the City's own codified text and is reproduced here rather than tidied. The City's separate Design Criteria and Adopted Codes web page states the same row as "Ice Shield Underlayment Required - Yes." The adopted 2021 International Residential Code conditions its ice barrier requirement on the designation made in Table R301.2, and Spearfish has made that designation in the affirmative, so Section R905.1.2 applies: an ice barrier of at least two layers of underlayment cemented together, or a self-adhering polymer modified bitumen sheet, extending from the eave edge to a point at least 24 inches inside the exterior wall line of the building. The requirement attaches to the work and not to the permit, so it applies to a reroof that is exempt from permit under Section 150.016(A)(1)(k) exactly as it applies to permitted work.
City of Tea, South Dakota - Planning, Zoning and Building Services (City of Tea, Lincoln County, South Dakota. Tea sits directly south of Sioux Falls and its city limits are the boundary that matters for both permitting and municipal tax, since the surrounding unincorporated Lincoln County land carries neither the City's permit requirement nor its municipal sales tax.)
Required, and stated twice by the City. Ordinance No. 299's Table R301.2, Climatic and Geographic Design Criteria, carries the entry "ICE BARRIER UNDERLAYMENT REQUIRED - Yes." The City's Asphalt Shingles Information handout gives the operative detail: "An ice barrier that consists of a least two layers of underlayment cemented together, or of a self-adhering polymer modified bitumen sheet, shall be used in lieu of normal underlayment, and extend from the eave's edge to a point at least 24 inches inside the exterior wall line of the building. The exception to this would be detached unheated structures." The transcription "a least" is the City's own and is reproduced rather than tidied. Note the exception on the face of that sentence: detached unheated structures. It is narrower than a blanket detached-garage exemption, since a heated detached garage is not within it, so confirm that specific case with the building official rather than assuming.
City of Vermillion, South Dakota - Code Enforcement Department (City of Vermillion, Clay County, South Dakota. The city limit is the boundary that matters for both the permit requirement and the municipal sales and use tax; the surrounding unincorporated Clay County land carries neither.)
Required. Section 150.03(B)(28) is Vermillion's own completed version of Table R301.2(1), Climatic and Geographic Design Criteria, and it carries the entry "Ice Barrier Underlayment Requirement yes." The adopted 2018 International Residential Code conditions its ice barrier requirement on the designation made in that table, and Vermillion has made the designation in the affirmative, so Section R905.1.2 applies: an ice barrier of at least two layers of underlayment cemented together, or a self-adhering polymer modified bitumen sheet, extending from the eave edge to a point at least 24 inches inside the exterior wall line of the building. Vermillion restates nothing further about how the barrier is to be installed, so the adopted code text is the whole of the local requirement.
Franklin County, Ohio - Building Department (Franklin County, Ohio -- unincorporated areas of the county plus the ten contract townships that route zoning compliance through the county (Brown, Clinton, Franklin, Hamilton, Madison, Mifflin, Norwich, Pleasant, Sharon and Truro townships). This does not include Columbus or the county's other incorporated cities and villages, which run their own separate residential permitting (see the Columbus, OH record for that city).)
SET BY STATE RULE. RCO Table 301.2(1) (OAC 4101:8-3-01, effective 7/1/2019), read in full from the state's own copy, pre-fills "Ice Barrier Underlayment Required" as "Yes" for the entire state, with footnote (h) reciting that "all jurisdictions in Ohio have a history of local damage from the effects of ice damming." RCO Section 905.1.2 requires the ice barrier to extend from the lowest roof edge to a point not less than 24 inches inside the exterior wall line (36 inches on slopes at or above 8:12), consisting of not fewer than two layers of cemented underlayment or a self-adhering polymer-modified bitumen sheet. No Franklin-County-specific roofing-permit form addressing ice barrier was found (unlike Parma's own form, which separately confirms the same requirement).
Montgomery County, Ohio - Building Regulations Division (Montgomery County, Ohio. The County states its own reach as "the citizens and users of buildings in many of the jurisdictions in Montgomery County, including all of the townships and several of the cities and villages." That is deliberately not a list, and this record does not turn it into one: all townships are covered, but which cities and villages are covered is not published here, so confirm the specific address with the Division before bidding.)
Required, and required across the whole state rather than in a mapped zone. Residential Code of Ohio section 905.1.2 conditions the ice barrier on a local history of ice damming "as designated in Table 301.2(1)", and Ohio's own Table 301.2(1) makes that designation statewide: the ICE BARRIER UNDERLAYMENT REQUIRED column reads "Yes", and note h to the table states that "all jurisdictions in Ohio have a history of local damage from the effects of ice damming." There is therefore no per-city determination to look up. The barrier "shall consist of not fewer than two layers of underlayment cemented together, or a self-adhering polymer-modified bitumen sheet shall be used in place of normal underlayment and extend from the lowest edges of all roof surfaces to a point not less than 24 inches (610 mm) inside the exterior wall line of the building," measured along the slope from where the projected outside face of the wall meets the deck. On roofs of 8:12 or steeper it "shall also be applied not less than 36 inches (914 mm) measured along the roof slope from the eave edge." One exception travels with it: "Detached accessory structures and roof assemblies terminating at a vertical wall over unconditioned floor areas." It applies to asphalt shingles, metal roof shingles, mineral surfaced roll roofing, slate and slate-type shingles, wood shingles and wood shakes.
Olmsted County, Minnesota - Planning Department, Inspections Division (Building code administration for four cities - Byron, Chatfield, Eyota and Stewartville - and three townships - Eyota, Marion and Quincy - within Olmsted County, Minnesota. This is not a county-wide authority and not an unincorporated-area authority. Olmsted County contains eight cities and eighteen townships; the County Planning Department's Inspections Division administers the Minnesota State Building Code for only the seven jurisdictions named above. Rochester is NOT among them - the County directs building and permitting questions inside Rochester city limits to the Rochester Building Safety department at 507-328-2600. The County states the scope itself: "The Olmsted County Planning department Inspections Division provides building code and permit administration for the cities of Byron, Chatfield, Eyota, and Stewartville as well as the townships of Eyota, Marion, and Quincy." Three other County boundaries deliberately differ and must not be conflated with this one: the Inspections Division administers the Septic System Ordinance for the townships of Eyota, Marion, Oronoco and Quincy "and for all of the small cities within Olmsted County," it administers the Water Well Ordinance "for the entire county," and it is the planning and zoning authority for only Eyota, Marion and Quincy Townships. One inconsistency is published on the County's own fees page and is reported rather than resolved: the building-permit section names the unincorporated areas of Marion, Quincy and Eyota Townships, while the manufactured-home, trade and septic sections on the same page each name Marion, Oronoco, Quincy and Eyota. Whether Oronoco Township is inside the building-permit jurisdiction is therefore stated both ways by the County. Because the County publishes an address-level Jurisdiction Checker, confirm a specific parcel there before assuming which desk holds a job.)
STATE-GOVERNED, NOT COUNTY-SET - the requirement applies identically in the jurisdictions Olmsted County serves as everywhere else in Minnesota. Minnesota Rules part 1309.0301, subpart 2 amends IRC Table R301.2(1) ("Climatic and Geographic Design Criteria") to pre-fill "ICE BARRIER UNDERLAYMENT REQUIRED[h] ... Yes" for the entire state. The Minnesota Department of Labor and Industry's guidance sheet, "Asphalt Shingle Roofing and the 2020 Minnesota Residential Code," describes what satisfies it: an ice barrier "may be at least two layers of underlayment cemented together or a self-adhering polymer modified bitumen sheet," extending from the eave edge to a point at least 24 inches inside the exterior wall line of the building. The County has no authority to opt out (Minn. Stat. 326B.121, subd. 1 and subd. 2(c), with "municipality" defined at Minn. Stat. 326B.103, subd. 9 to include a county). Garage and detached-accessory-structure applicability is worded differently by different Minnesota jurisdictions, so confirm that specific case with the Inspections Division rather than assuming a blanket detached-garage exemption.
Scott County, Iowa - Planning & Development Department (Unincorporated Scott County, Iowa, plus the Cities of Dixon, Donahue, LeClaire, Long Grove, McCausland, Panorama Park, Princeton, and Riverdale under a 28E intergovernmental agreement. Davenport and Bettendorf are explicitly excluded — those two cities issue their own building permits.)
Scott County's own Table R301.2 insert, added by Ordinance No. 24-07 Sec. 5-6 item F (applicable to the 2021 IRC as adopted by the same ordinance), lists "Ice Barrier Underlayment Required: Yes" as a filled-in table value for the jurisdiction.
Stark County, Ohio - Building Department (Unincorporated Stark County, Ohio, plus contracting villages. For RESIDENTIAL work the County's own jurisdiction directory covers the townships of Bethlehem, Canton, Jackson, Lake, Lawrence, Lexington, Marlboro, Nimishillen, Osnaburg, Paris, Perry, Pike, Plain, Sandy, Sugarcreek, Tuscarawas and Washington, and the villages of Brewster, East Canton, Harmon, Hills and Dales, Magnolia, Meyers Lake, Minerva and Waynesburg. Alliance, Beach City, East Sparta, Hartville, Louisville, Navarre and Wilmot are listed for COMMERCIAL work only, so residential roofing in those seven is not this authority's. Canal Fulton, Canton, Massillon and North Canton are outside the County's jurisdiction entirely and run their own building departments.)
Required, and required across the whole state rather than in a mapped zone. Residential Code of Ohio section 905.1.2 conditions the ice barrier on a local history of ice damming "as designated in Table 301.2(1)", and Ohio's own Table 301.2(1) makes that designation statewide: the ICE BARRIER UNDERLAYMENT REQUIRED column reads "Yes", and note h to the table states that "all jurisdictions in Ohio have a history of local damage from the effects of ice damming." Stark County reprints the requirement on its Residential Guidelines for Reroof form, so it is the County's published expectation and not merely a state rule. The barrier "shall consist of not fewer than two layers of underlayment cemented together, or a self-adhering polymer-modified bitumen sheet shall be used in place of normal underlayment and extend from the lowest edges of all roof surfaces to a point not less than 24 inches (610 mm) inside the exterior wall line of the building," measured along the slope from where the projected outside face of the wall meets the deck. On roofs of 8:12 or steeper it "shall also be applied not less than 36 inches (914 mm) measured along the roof slope from the eave edge." One exception travels with it and the County prints it too: "Detached accessory structures and roof assemblies terminating at a vertical wall over unconditioned floor areas." It applies to asphalt shingles, metal roof shingles, mineral surfaced roll roofing, slate and slate-type shingles, wood shingles and wood shakes.

City of Central Falls - Code Enforcement (City of Central Falls, Rhode Island)
Required statewide. Rhode Island replaces the International Residential Code's Table R301.2(1) with its own table for the whole state, and that table reads "Ice Shield Underlayment Required" "Yes" (510-RICR-00-00-2, R301.2). Section R905.1.2, adopted unchanged, then requires an ice barrier "for asphalt shingles, metal roof shingles, mineral-surfaced roll roofing, slate and slate-type shingles, wood shingles and wood shakes," consisting of "not fewer than two layers of underlayment cemented together, or a self-adhering polymer-modified bitumen sheet," extending "from the lowest edges of all roof surfaces to a point not less than 24 inches (610 mm) inside the exterior wall line of the building," and on roofs of 8:12 slope or steeper also "not less than 36 inches (914 mm) measured along the roof slope from the eave edge of the building." The rule does not apply to "Detached accessory structures not containing conditioned floor area." On a tear-off, an ice barrier membrane adhered to the deck may stay and be covered with an additional layer (R908.3, Exception). Everything above is Rhode Island state law, the same in every city and town.

On a tear-off, an ice barrier membrane adhered to the deck may stay and be covered with an additional layer (R908.3, Exception). Everything above is Rhode Island state law, the same in every city and town. In Westerly the Town's Building Office, which its own page describes as the Town's code enforcement office and the place where all permits are issued, enforces the code.
Ice barrier required — South Dakota (11)
City of Aberdeen, South Dakota - Building Inspection Department (City of Aberdeen, South Dakota)
The City's own "Residential Shingling Guide" states: "Aberdeen, SD is designated as an area subject to ice forming along eaves and thus causing water backup. An approved ice barrier shall be installed under all types of roofing unless specified otherwise by the manufacturer." The guide separately exempts detached garages and other unconditioned, non-habitable structures from the ice-barrier requirement, and states: "Ice barriers shall extend from the lowest edge of all roof surfaces to a point not less than 24 inches inside the exterior wall line of the building. Roofs having a slope equal or greater than 8 units vertical in 12 units horizontal (8 in 12 pitch), the ice barrier shall be applied not less than 36 inches measured along the roof slope from the eave edge of the building." This matches the City's own amendment to Table R301.2(1) of the adopted 2018 IRC (Sec. 12-21(2)), which fills in "Ice barrier underlayment required" as "Yes."
City of Box Elder, South Dakota - Planning and Zoning Department (City of Box Elder, Pennington and Meade Counties, South Dakota)
AN AFFIRMATIVE LOCAL MANDATE, not an inference from a design criteria table. Box Elder amends the ice barrier twice, in the general roofing section and again in the asphalt shingle section, in identical terms. Sec. 6-257 (amending IRC R905.1.2) and Sec. 6-258 (amending IRC R905.2.7.1) both read: "Ice barrier is required. An ice barrier that consists of a least two layers of underlayment cemented together or of a self-adhering polymer modified bitumen sheet, shall be used in lieu of normal underlayment and extend from the lowest edges of all roof surfaces to a point at least 24 inches (610 mm) inside the exterior wall line of the building. Exception: Detached accessory structures that contain no conditioned floor area." ("a least" is the codification's own typographical error for "at least"; quoted as published.) Both sections derive from Ord. No. 642, 2-14-2020 and were amended by Ord. 748, 6/5/2024. The City's climatic and geographic design criteria table corroborates it, carrying "Ice Barrier Underlay Requirement: Yes." The only exception is the detached accessory structure with no conditioned floor area, so an unheated detached garage is treated differently from the house.
City of Brandon, South Dakota - Planning and Inspection Department (City of Brandon, Minnehaha County, South Dakota)
Required. Brandon fills in IRC Table R301.2(1), Climatic and Geographic Design Criteria, and its entry for "Ice barrier underlayment required" is "Yes". Because Brandon amends no section of the roofing chapter, the base code attaches to that entry unmodified: 2021 IRC R905.1.2 makes the ice barrier mandatory in jurisdictions where Table R301.2(1) so indicates, and the model footnote Brandon reproduces states the test the City was answering - "where there has been a history of local damage from the effects of ice damming, the jurisdiction shall fill in this part of the table with 'YES.' Otherwise, the jurisdiction shall fill in this part of the table with 'NO.'" Brandon answered YES. The rest of the City's filled table, from the same amendment: ground snow load 40 psf; seismic design category A; weathering severe; frost line depth 42 inches; termite slight to moderate; winter design temperature -11 degrees F; air freezing index 3,000; mean annual temperature 46 degrees F. One cell of that table was plainly adapted from a neighbouring city and has not been corrected: the flood hazards entry reads "Sioux Falls entered the regular phase of the National Flood Insurance Program on September 17, 1979," naming Sioux Falls rather than Brandon. It does not touch any roofing value, but it is a reason to confirm an unusual design figure with the Building Department on 605-582-8987 rather than reading it off the table alone.
City of Brookings, South Dakota - Community Development Department, Building Services Division (City of Brookings, South Dakota)
Ordinance No. 23-008 fills in Table R301.2 (Climatic and Geographic Design Criteria) for Brookings; line 8 of that table, as printed in the city's own ordinance, reads "Ice barrier underlayment requirement ... Yes." Under the 2021 IRC, that Table R301.2 entry is what triggers the ice-barrier-underlayment requirement, and Brookings' own adopting ordinance sets it to Yes.
City of Harrisburg, South Dakota - Building Services (City of Harrisburg, Lincoln County, South Dakota)
Required. Ordinance #2021-17 fills in the City's climatic and geographic design criteria by amendment: "Table R301.2 Climatic and Geographic Design Criteria, is hereby amended by inserting the following information into the table: ... Ice Barrier Underlayment Required: Yes;" Because Harrisburg amends no section of the roofing chapter, the base code attaches to that entry unmodified - 2021 IRC R905.1.2 makes the ice barrier mandatory in jurisdictions where Table R301.2(1) so indicates. An ice barrier under that section is at least two layers of underlayment cemented together or a self-adhering polymer modified bitumen sheet, extending from the eave edge to a point at least 24 inches inside the exterior wall line of the building. Other values inserted by the same amendment: ground snow load 40 psf; topographic effects no; special wind region no; windborne debris zone no.
City of Pierre, South Dakota - Development Services, Building Department (City of Pierre, South Dakota)
The city's Chapter 11, Article 4 amends Section R905.1.2 (Ice Barrier) directly: "In areas where there has been a history of ice forming along the eaves causing a backup of water as designated in Table R301.2(1), an ice barrier shall be installed for asphalt shingles, metal roof shingles, mineral surfaced roll roofing, slate and slate-type shingles, wood shingles and wood shakes," extending "at least 24 inches inside the exterior wall line" on roofs under 5:12 pitch and 36 inches on roofs 5:12 or steeper. The article's own Table R301.2(1) climatic and geographic design criteria table sets "Ice Barrier Underlayment Required: Yes" for Pierre.
City of Rapid City, South Dakota - Community Planning & Development Services, Building Services Division (City of Rapid City, South Dakota)
Locally amended, not left to the baseline model-code trigger. RCMC 15.13.270 is titled "IRC Chapter 9, Section R905.1.2 Ice barrier--Amended" and amends that section of the adopted 2018 IRC to read in its entirety as follows, quoted from the section read live on 2026-08-08: "R905.1.2 Ice barrier. In areas where there has been a history of ice forming along the eaves causing a backup of water as designated in Table R301.2(1), an ice barrier that consists of a least two layers of underlayment cemented together or of a self-adhering polymer modified bitumen sheet, shall be used in lieu of normal underlayment and extend from the lowest edges of all roof surfaces to a point at least 24 inches (610 mm) inside the exterior wall line of the building." (The "a least" is the code's own typographical error, reproduced here rather than silently repaired.) The amended section carries ONE exception - "Detached accessory structures that contain no conditioned floor area" - and one further operative sentence that a roofer must plan around: "If the ice shield is not inspected, the contractor shall provide an affidavit that the ice shield materials were installed properly." That affidavit is the discharge route when the RCMC 15.04.280(A)(7) ice barrier inspection does not happen; see midroof_inspection_required. Section history: Ord. 6270, 2019; Ord. 6009, 2015; Ord. 5891, 2013; Ord. 5819, 2012. SCOPE LIMITS, stated because an earlier draft of this field overstated them: the Rapid City amendment contains NO 8-in-12 slope trigger, NO 36-inch measured-along-the-slope requirement, and NO enumerated list of covered roof coverings - the single dimensional requirement it imposes is the 24 inches inside the exterior wall line. Separately, RCMC 15.13.280 assumes ice barrier membrane may be present in existing assemblies, permitting an adhered existing ice barrier to remain in place and be covered with an additional layer of ice barrier membrane in accordance with Section R905.
City of Sioux Falls, South Dakota - Planning and Development Services, Building Services Division (City of Sioux Falls, South Dakota)
The City of Sioux Falls publishes its own "Asphalt Shingles Information Sheet" in its Homeowner's Construction Guides set, and that sheet carries the ice-barrier requirement for roofs in the city: an ice barrier of not fewer than two layers of underlayment cemented together, or a self-adhering polymer-modified bitumen sheet used in place of normal underlayment, extending from the eave edge to a point not less than 24 inches inside the exterior wall line of the building. I opened both the homeowner-construction-guide copy of this sheet and the city's separately-linked "Asphalt Shingle Information Sheet" at https://www.siouxfalls.gov/files/assets/public/v/2/business-and-permits/ordinances/homeowner-construction/asphalt-shingle-information-sheet.pdf and confirmed both URLs currently serve the identical scanned document (byte-for-byte matching file); reading it in full (8 pages) found no printed date, so the two URLs are not two different editions. The document cites ASTM D7158/D3161 wind-classification and ASTM D1970 self-adhering-membrane standards and uses current IRC R905-series section language, consistent with the city's current 2021 IRC adoption rather than a stale pre-2021 edition. Note that under the 2021 IRC the ice barrier applies only where the jurisdiction has filled in Table R301.2(1) with "YES" for ice-barrier underlayment, which is a Sioux Falls-specific entry in the city's adopting ordinance rather than a South Dakota statewide determination - South Dakota sets no statewide ice-barrier rule.
City of Sturgis, South Dakota - Building Inspector's Office (City of Sturgis, Meade County, South Dakota)
Required, and it is one of only three local modifications Sturgis makes to the residential code. Section 2.02.01(1), inside the adoption itself, ends with the words "and figure 905.1.2 Ice and water barrier membrane required." The citation style is the City's own and is quoted as written: the provision it points at is Section R905.1.2 of the International Residential Code, Ice barrier, rather than a figure, and the same subsection uses "figure" the same loose way for its other two modifications. The requirement itself is unambiguous. Under the adopted 2021 code that means an ice barrier of at least two layers of underlayment cemented together, or a self-adhering polymer modified bitumen sheet, extending from the eave edge to a point at least 24 inches inside the exterior wall line of the building. Because Sturgis states the requirement in its own adopting ordinance rather than leaving it to the designation cell of Table R301.2, it does not depend on a climatic table the City has otherwise left largely blank.
City of Watertown, South Dakota - Building Inspection / Licenses & Permits (City of Watertown, South Dakota)
Table R301.2(1), as filled in by the city's amendment (Ord 18-27, Rev 12-28-18), states "Ice Shield Underlayment Required - Yes." The city separately amends IRC Sec. R905.1.2 (Ice Barrier), extending the required membrane from the base-code 24 inches to 36 inches inside the exterior wall line: "Section R905.1.2 Ice Barrier. Amend '24 inches (610 mm) inside the exterior wall line of the building' to '36 inches'."
City of Yankton, South Dakota - Community and Economic Development, Building Services & Permits (City of Yankton, South Dakota)
The city's Asphalt Shingle Roofing Guidelines handout states: "Ice and water shield installed minimum 24" inside exterior wall line. Underlayment installed per manufacturer's requirements based on slope and material type," and specifies a single layer of ice-dam protection membrane for roof slopes greater than 4:12 and a double layer for slopes between 2:12 and 4:12, illustrated with the city's own single-layer and double-layer underlayment diagrams.
Ice barrier required — Tennessee (1)
Ice barrier required — Utah (8)
Greater Salt Lake Municipal Services District, Building Services (Greater Salt Lake Municipal Services District, Utah)
The District's own Codes and Design Criteria page states its Table R301.2(1) entry for "Ice Shield Underlayment" as "Yes" for every community it serves, alongside "Weathering: Severe," "Winter Design Temp: 8 F," "Air Freezing Index: <=1500," and "Mean Annual Temp: 45 F."
Herriman City - Building Department (City of Herriman, Utah)
Herriman's own Table R301.2(1), "Climatic and Geographic Design Criteria" (a City-published PDF, image-only and read by rendering rather than text extraction), lists "ICE BARRIER UNDERLAYMENT REQUIRED: Yes." Separately, the City's own Re-Roofs page states that a re-roof's required mid-roof inspection occurs "after all shingles are removed and flashings and ice and water shields are in place," confirming the membrane is a standard, checked element of a compliant Herriman re-roof rather than only a table entry.
Millcreek City - Building Department (City of Millcreek, Utah)
Millcreek's own Climate and Geographic Design Criteria, published on the City's Building Department page and as a standalone PDF, states: "Ice Barrier Underlayment Required: Yes." The same table publishes an "Air Freezing Index" of 2500 (BF-Days) and a "Mean Annual Temperature" of 53.6 degrees Fahrenheit, both City-published figures a roofer would need alongside the underlayment requirement.
Provo City - Development Services, Building Division (City of Provo, Utah)
Provo's own Building Division Design Criteria page publishes a plan-review table stating "Ice barrier underlayment requirement" as "YES," alongside an Air Freezing Index of 834 and a Mean Annual Temperature of 53.5 degrees Fahrenheit, all for the Provo location.
Salt Lake City Building Services (Salt Lake City, Utah)
Salt Lake City Building Services' own "Design Criteria" document, at item 12, states plainly: "ICE SHIELD UNDERLAYMENT: Yes." The document does not further specify a roof-slope or eave exception beyond that stated requirement.
South Jordan City - Building Department (City of South Jordan, Utah)
South Jordan's Building Department publishes a signed "Re-Roof Requirements Official Statement," over the Chief Building Official's signature, stating: "Referenced codes include requirements for ventilation, ice and water shield, drainage performance and other criteria that must be followed," and that all roof work "are required to follow all the State and City adopted codes." The Department's own Design Criteria page separately states a Frost Depth of "30 inches minimum from the bottom of the footing to the finished grade," published alongside the same code list.
West Jordan City - Community Development, Building & Safety Division (City of West Jordan, Utah)
West Jordan's own Building & Safety Division Design Criteria page (last revised 07/2026) lists, among its published plan-review criteria: "ICE SHIELD UNDERLAYMENT: Yes." The same page states an "AIR FREEZING INDEX: <= 1000" and a "WINTER DESIGN TEMP: 8 F," both City-published figures a roofer would need alongside the underlayment requirement.
West Valley City Building Inspection Division (West Valley City, Utah)
Required by West Valley City's own current Design Criteria sheet, effective April 18, 2026, which lists "Ice Shield Underlayment Required: Yes" on its Table R301.2(1) climatic design criteria for the city.
Ice barrier required — Virginia (15)
Campbell County - Building Inspections Office (Campbell County, Virginia)
Campbell County's own Design Criteria page answers "Ice Barrier Underlayment Required" with "Yes". A reroof that needs no permit still has to meet the code: the statewide permit exemption "shall not be construed to exempt such activities from other applicable requirements of this code".
City of Fairfax - Office of Code Administration (City of Fairfax, Virginia)
City of Fairfax City Code Sec. 10-45 inserts the City's values into Table R301.2(1) of the Virginia Residential Code and lists "Ice Barrier Underlayment Required" as "YES" for the City (Ord. No. 2012-20, adopted November 27, 2012).
City of Petersburg - Code Compliance Division (City of Petersburg, Virginia)
The City of Petersburg Local Design Criteria, the City's own list of climatic design parameters for residential one- and two-family construction, answers "Ice Shield Required?" with "Yes" (ground snow load 20 psf; winter design temperature 17 degrees F; air freezing index 1500).
Fairfax County - Land Development Services (Fairfax County, Virginia)
Fairfax County's Local Design Load Criteria, the County's completion of the climatic and geographic design criteria that the Virginia code leaves to each locality, list "Ice shield underlayment required" as "yes". Virginia makes no amendment to the residential code's ice-barrier provisions.
Fluvanna County - Building Inspections (Fluvanna County, Virginia)
Fluvanna County's own 2021 IRC Table 301.2(1), Climatic and Geographic Design Criteria, published by Building Inspections, answers "ICE BARRIER REQUIRED" with "YES". A reroof that needs no permit still has to meet the code: the statewide permit exemption "shall not be construed to exempt such activities from other applicable requirements of this code".
Gloucester County - Building Inspection Department (Gloucester County, Virginia)
Gloucester County's Basic Design Criteria sheet, the Building Inspection Department's statement of its Table R301.2(1) values, answers "Ice Barrier Underlayment Required" with "Yes". The sheet (revised 3-21-2023) is headed "2018 USBC-VRC"; the County has published no separate table for the 2021 code. Virginia makes no amendment to the residential code's ice-barrier provisions. A reroof that needs no permit still has to meet the code: the statewide permit exemption "shall not be construed to exempt such activities from other applicable requirements of this code".
Goochland County - Department of Building Inspection (Goochland County, Virginia)
Goochland County's Design Criteria page ("Goochland County maintains the following design criteria") lists "Ice barrier underlayment: Yes", and the County's Develop Property FAQ lists "Ice Barrier Underlayment: Yes" in its basic design criteria for the County.
Henrico County - Department of Building Construction and Inspections (Henrico County, Virginia)
Henrico County's Climatic and Geographic Design Criteria page lists "Ice Barrier required: Yes" for the County. That is the County's entry for the ice barrier line of the Virginia Residential Code's climatic design criteria table, which Virginia leaves to each locality to complete, so an ice barrier is required where the code's shingle underlayment provisions apply (IRC Section R905.1.2).
James City County - Building Safety and Permits Division (James City County, Virginia)
James City County's enacted entries in the Virginia Residential Code's climatic table (County Code Section 4-3, Table R301.2, Ord. No. 81A-29, 3-11-25) read "ICE Barrier Underlayment: Yes, required". The ice barrier is therefore part of the design criteria for houses in the county.
Louisa County - Building Inspections Division (Louisa County, Virginia)
Louisa County's Design Criteria Chart (Table R301.2(1), Climatic and Geographic Design Criteria, on Community Development letterhead and posted on the County's Virginia Building Code page) lists "Ice Barrier Underlayment Required" as "Yes" for the County.
Prince William County - Building Development Division (Prince William County, Virginia (unincorporated))
The County's completed Table R301.2(1) (Building Development policy "Climatic and Geographic Design Criteria", effective November 16, 2006, revised December 20, 2020) answers "Yes" in its Ice Barrier Underlayment Required column for Prince William County. The County's "Protection from Ice Damming" policy (revised May 1, 2025) states that "buildings in Prince William County shall have ice shield underlayment", for asphalt shingles, metal roof shingles, mineral-surfaced roll roofing, slate and slate-type shingles, wood shingles and wood shakes, and the Residential Roof Replacements handout answers "Do I need to install 'ice shield'?" with "The VUSBC does require the installation of 'ice shield'."
Pulaski County - Building Office (Pulaski County, Virginia)
The County's Information for Designers sheet ("Local Design Criteria for Pulaski County"), in its Residential 1 & 2 Family Construction Design Parameters, answers "Yes" under "Ice Shield Req?". The sheet does not say how far up the roof the ice barrier must extend, so use the building code and the shingle manufacturer's installation instructions for the detail. The sheet's opening line refers to the 2018 editions of the codes while its code-edition box names the 2021 edition.
Shenandoah County - Building Inspection (Shenandoah County, Virginia)
Shenandoah County's Design Information page, which lists the County's climatic design values under the 2021 code, answers "Ice barrier underlayment requirement, Yes". Ask Building Inspection (540-459-6185) how it applies the entry to a reroof; a shingle manufacturer's installation instructions also apply to the job.
Spotsylvania County - Building Safety Office (Spotsylvania County, Virginia)
The Spotsylvania County Building Safety Department's Table R301.2(1), Climatic and Geographic Design Criteria (published as "Spotsylvania County Design Criteria 2021", sheet footer dated 01-09-2025), answers "YES" in its Ice Barrier Underlayment Required column.
Stafford County - Building Division, Department of Development Services (Stafford County, Virginia)
Stafford County's Design Criteria page (Building Division, Codes and Standards) lists "ICE/WATER SHIELD REQUIRED Yes", and the Department of Development Services' "Ice Barrier and Drip Edge Requirements" sheet, a "Jurisdictional determination for ice shield and drip edge requirements" dated 8-8-17, states "Ice Barriers are required per the 2012 Virginia Residential Code (IRC with VUSBC amendments) per section 905.8.3.1". Both County statements name earlier code editions (the Design Criteria page says its criteria "are based on Chapter 16 of the 2018 Virginia Construction Code, the 2005 ASCE-7 and Chapter 3 of the 2018 Virginia Residential Code"); the 2021 Uniform Statewide Building Code now applies.
Ice barrier required — Wisconsin (139)
City of Algoma - Building Inspector (City of Algoma, Wisconsin)
STATE-GOVERNED, NOT LOCALLY SET, but SCOPE-LIMITED BY ROOF SLOPE -- read the trigger before pricing the job. Wis. Admin. Code § SPS 321.28(4)(a) requires ice dam protection on shingled or shake roofs that extend over a heated area of the dwelling or an attached garage AND that have a slope of 4:12 or less; the protection must be sheet metal or a product labeled as meeting ASTM D1970. Wisconsin's UDC therefore does not impose the IRC's across-the-board cold-climate ice barrier on steeper roofs -- it is a Wisconsin-drafted rule, not an IRC clone. Extent, verbatim, SPS 321.28(4)(b): the ice dam protection "shall extend at least 30 inches up the roof slope from the roof edge and at least 12 inches up the roof slope beyond the inner face of the exterior wall." That is a different measurement convention from the IRC's 24-inches-inside-the-exterior-wall-line rule -- do not substitute IRC ice-barrier language on a Wisconsin job. Algoma may not impose a different ice-barrier rule on a one- or two-family dwelling (Wis. Stat. § 101.65(1c)). The mandate genuinely exists in Wisconsin code, but it is the 4:12-or-less slope condition described here, not the bare yes-or-no answer, that governs a given roof. SCOPE -- the same Uniform Dwelling Code limits that govern the layer rule govern this one, because Wis. Admin. Code SPS 320.05 exempts work from the code as a whole rather than from any single section. SPS 320.05(1) excludes dwellings whose construction commenced before the code's effective date, and additions or alterations to such dwellings, unless the municipality has adopted chs. SPS 320 to 325 for that purpose -- whether Algoma has done so is NOT established by this record. That date is June 1, 1980 for chs. SPS 320, 321, 323, 324 and 325 under SPS 320.03. Wis. Stat. 101.615 states December 1, 1978, but SPS 320.03 assigns that date to ch. SPS 322, the energy chapter; for a reroof, which is governed by chs. SPS 320 and 321, June 1, 1980 is the date that governs. SPS 320.05(3) further excludes "repairs or maintenance to dwellings or dwelling units," and SPS 320.07(61) defines "repair" to include "the replacement of existing fixtures, systems or equipment with the equivalent" fixture, system or equipment. On a dwelling built before 1980, confirm with the City of Algoma Building Inspector that the ice dam rule applies before pricing it in or out.
City of Altoona - Building Inspection (City of Altoona, Wisconsin)
STATE-GOVERNED, NOT LOCALLY SET, but SCOPE-LIMITED BY ROOF SLOPE -- read the trigger before pricing the job. Wis. Admin. Code § SPS 321.28(4)(a) requires ice dam protection on shingled or shake roofs that extend over a heated area of the dwelling or an attached garage AND that have a slope of 4:12 or less; the protection must be sheet metal or a product labeled as meeting ASTM D1970.

On a dwelling built before 1980, confirm with the City of Antigo Building Inspections Department that the ice dam rule applies before pricing it in or out.
City of Appleton, Wisconsin - Community Development Department, Inspections Division (City of Appleton, Wisconsin)
Required, but on a narrower trigger than the International Residential Code uses - read the slope condition before pricing it in or out. Wis. Admin. Code SPS 321.28(4)(a) requires that shingled or shake roofs that extend over a heated area of a dwelling or attached garage and that have a slope of 4:12 or less be provided with ice dam protection in the form of sheet metal or a product labeled as meeting the requirements of ASTM D 1970. SPS 321.28(4)(b) sets the extent: the protection "shall extend at least 30 inches up the roof slope from the roof edge and at least 12 inches up the roof slope beyond the inner face of the exterior wall." Three conditions all have to be met - a shingle or shake covering, a heated area below, and a slope of 4:12 or less - so a steeper roof is not covered by this requirement at all, which is where Wisconsin differs from the IRC climate-zone rule. Wisconsin also measures the extent differently from the IRC, 30 inches up the slope from the roof edge and 12 inches past the inner face of the exterior wall, so do not substitute IRC ice-barrier language on an Appleton job. On a steep-slope roof the shingle manufacturer instructions may still call for an ice barrier, and SPS 321.28(3)(a) makes those instructions binding. SCOPE: The Wisconsin uniform dwelling code sets these roofing rules statewide, but does not reach every house. It does not apply to a one- or two-family dwelling whose construction began before June 1, 1980, or to additions or alterations to one, unless the municipality has adopted chs. SPS 320 to 325 for that purpose — ask the building inspector before assuming it governs an older home. The code also states that it does not apply to repairs or maintenance, and it defines a repair to include replacing existing equipment with the equivalent, while a separate section regulates reroofing by name. Wisconsin has not resolved which of those two provisions governs a like-for-like tear-off, so confirm with the authority issuing the permit. In Appleton the age half of that scope question is settled by the City itself: Municipal Code Sec. 4-140(c) applies the adopted Uniform Dwelling Code to existing one- and two-family buildings "but only to the extent such existing buildings are remodeled, reconstructed or added to", so an older Appleton house is not outside the ice dam rule merely because it predates June 1, 1980.
City of Ashland - Planning and Development Department (City of Ashland, Wisconsin)
STATE-GOVERNED, NOT LOCALLY SET, but SCOPE-LIMITED BY ROOF SLOPE -- read the trigger before pricing the job. Wis. Admin. Code § SPS 321.28(4)(a) requires ice dam protection on shingled or shake roofs that extend over a heated area of the dwelling or an attached garage AND that have a slope of 4:12 or less; the protection must be sheet metal or a product labeled as meeting ASTM D1970. Wisconsin's UDC therefore does not impose the IRC's across-the-board cold-climate ice barrier on steeper roofs -- it is a Wisconsin-drafted rule, not an IRC clone. Extent, verbatim, SPS 321.28(4)(b): the ice dam protection "shall extend at least 30 inches up the roof slope from the roof edge and at least 12 inches up the roof slope beyond the inner face of the exterior wall." That is a different measurement convention from the IRC's 24-inches-inside-the-exterior-wall-line rule -- do not substitute IRC ice-barrier language on a Wisconsin job. Ashland may not impose a different ice-barrier rule on a one- or two-family dwelling (Wis. Stat. § 101.65(1c)). The mandate genuinely exists in Wisconsin code, but it is the 4:12-or-less slope condition described here, not the bare yes-or-no answer, that governs a given roof. SCOPE -- the same Uniform Dwelling Code limits that govern the layer rule govern this one, because Wis. Admin. Code SPS 320.05 exempts work from the code as a whole rather than from any single section. SPS 320.05(1) excludes dwellings whose construction commenced before the code's effective date, and additions or alterations to such dwellings, unless the municipality has adopted chs. SPS 320 to 325 for that purpose -- whether Ashland has done so is NOT established by this record. That date is June 1, 1980 for chs. SPS 320, 321, 323, 324 and 325 under SPS 320.03. Wis. Stat. 101.615 states December 1, 1978, but SPS 320.03 assigns that date to ch. SPS 322, the energy chapter; for a reroof, which is governed by chs. SPS 320 and 321, June 1, 1980 is the date that governs. SPS 320.05(3) further excludes "repairs or maintenance to dwellings or dwelling units," and SPS 320.07(61) defines "repair" to include "the replacement of existing fixtures, systems or equipment with the equivalent" fixture, system or equipment. On a dwelling built before 1980, confirm with the City of Ashland Planning and Development Department that the ice dam rule applies before pricing it in or out.
City of Baraboo, Wisconsin - Department of Building Inspection (City of Baraboo, Wisconsin)
STATE-GOVERNED via Sec. 14.05's adoption of the Uniform Dwelling Code, SCOPE-LIMITED BY ROOF SLOPE, and NOT independently addressed by Baraboo's own local roofing ordinance (Sec. 14.10(4), read in full, has no ice-dam provision). Wis. Admin. Code Sec. SPS 321.28(4)(a) requires ice dam protection on "[s]hingled or shake roofs that extend over a heated area of a dwelling or attached garage" AND that "have a slope of 4:12 or less," in the form of "sheet metal or a product labeled as meeting the requirements of ASTM D 1970." Extent, Sec. 321.28(4)(b): the protection "shall extend at least 30 inches up the roof slope from the roof edge and at least 12 inches up the roof slope beyond the inner face of the exterior wall." That is a different measurement convention from the IRC's "24 inches inside the exterior wall line" -- do not substitute IRC ice-barrier language on a Wisconsin job. SCOPE: the Uniform Dwelling Code does not reach every dwelling. Wis. Admin. Code SPS 320.05(1) provides that the code "shall not apply to dwellings and dwelling units, the construction of which was commenced prior to the effective date of this code, or to additions or alterations to such dwellings"; SPS 320.03 fixes that effective date, for chs. SPS 320, 321, 323, 324 and 325, at June 1, 1980. A note to SPS 320.05(1) states chs. SPS 320 to 325 "may be adopted by a municipality to apply to any additions or alterations to existing dwellings" -- whether Baraboo has done so for THIS state-law basis is NOT established by this record (Baraboo's Sec. 14.05 adopts the Uniform Dwelling Code generally and does not separately address pre-1980 alterations). SPS 320.05(3) further provides the code does "not apply to repairs or maintenance to dwellings or dwelling units," and SPS 320.07(61) defines "repair" to include "the replacement of existing fixtures, systems or equipment with the equivalent fixture, system or equipment" -- a fair description of a like-for-like tear-off and replacement -- while SPS 321.28 regulates roofing installation by name. Those two provisions are in genuine tension; this record states both and does not adjudicate between them. On a dwelling built before 1980, or on a like-for-like replacement, confirm scope with the City of Baraboo Building Inspection Department before relying on this field.
City of Beaver Dam - Inspection Services (City of Beaver Dam, Wisconsin)
STATE-GOVERNED, NOT LOCALLY SET, but SCOPE-LIMITED BY ROOF SLOPE -- read the trigger before pricing the job. Wis. Admin. Code § SPS 321.28(4)(a) requires ice dam protection on shingled or shake roofs that extend over a heated area of the dwelling or an attached garage AND that have a slope of 4:12 or less; the protection must be sheet metal or a product labeled as meeting ASTM D1970. Wisconsin's UDC therefore does not impose the IRC's across-the-board cold-climate ice barrier on steeper roofs -- it is a Wisconsin-drafted rule, not an IRC clone.

That is a different measurement convention from the IRC's 24-inches-inside-the-exterior-wall-line rule -- do not substitute IRC ice-barrier language on a Wisconsin job. Beaver Dam may not impose a different ice-barrier rule on a one- or two-family dwelling (Wis. Stat. § 101.65(1c)). The mandate genuinely exists in Wisconsin code, but it is the 4:12-or-less slope condition described here, not the bare yes-or-no answer, that governs a given roof. SCOPE -- the same Uniform Dwelling Code limits that govern the layer rule govern this one, because Wis. Admin. Code SPS 320.05 exempts work from the code as a whole rather than from any single section. SPS 320.05(1) excludes dwellings whose construction commenced before the code's effective date, and additions or alterations to such dwellings, unless the municipality has adopted chs. SPS 320 to 325 for that purpose -- whether Beaver Dam has done so is NOT established by this record. That date is June 1, 1980 for chs. SPS 320, 321, 323, 324 and 325 under SPS 320.03. Wis.

SPS 320.05(3) further excludes "repairs or maintenance to dwellings or dwelling units," and SPS 320.07(61) defines "repair" to include "the replacement of existing fixtures, systems or equipment with the equivalent" fixture, system or equipment. On a dwelling built before 1980, confirm with the City of Beaver Dam Inspection Services department that the ice dam rule applies before pricing it in or out.
City of Beloit, Wisconsin - Planning and Building Services Division (City of Beloit, Wisconsin)
Required, but the trigger is roof slope rather than climate zone, so read the scope before pricing it in or out. Wis. Admin. Code SPS 321.28(4)(a) requires that "Shingled or shake roofs that extend over a heated area of a dwelling or attached garage and that have a slope of 4:12 or less shall be provided with ice dam protection in the form of sheet metal or a product labeled as meeting the requirements of ASTM D 1970." SPS 321.28(4)(b) sets the extent: "The ice dam protection shall extend at least 30 inches up the roof slope from the roof edge and at least 12 inches up the roof slope beyond the inner face of the exterior wall." All three conditions have to be met — shingled or shake, over a heated area, and 4:12 or flatter — so on a steeper Beloit roof the Uniform Dwelling Code imposes no ice barrier of its own, though the shingle manufacturer's own instructions may, since SPS 321.28(3)(a) requires shingles to be installed in accordance with those instructions. Wisconsin also measures the extent differently from the International Residential Code, so do not carry IRC ice-barrier language onto a Wisconsin job. Beloit adopts the state code and adds no ice-barrier rule of its own. The Wisconsin uniform dwelling code sets these roofing rules statewide, but does not reach every house. It does not apply to a one- or two-family dwelling whose construction began before June 1, 1980, or to additions or alterations to one, unless the municipality has adopted chs. SPS 320 to 325 for that purpose — ask the building inspector before assuming it governs an older home. The code also states that it does not apply to repairs or maintenance, and it defines a repair to include replacing existing equipment with the equivalent, while a separate section regulates reroofing by name. Wisconsin has not resolved which of those two provisions governs a like-for-like tear-off, so confirm with the authority issuing the permit. In Beloit the first of those two questions is settled, and in the roofer's favour on an older house. Beloit Municipal Code section 9.04(3) provides that for the purposes of local regulation of one- and two-family dwellings the provisions of the Uniform Dwelling Code apply to additions and alterations to buildings whose initial construction was lawfully begun before June 1, 1980 -- a building-vintage cutoff that passed decades ago rather than a future effective date -- and that those provisions apply to the addition being constructed or the work involved in the alterations or repairs and shall not be construed to apply to the existing building. So the age of the house does not put a Beloit reroof outside the code, and the code reaches the roof work rather than the rest of the building. The repair question is not touched by that ordinance and stays open.
City of Berlin - Building Inspection & Zoning (City of Berlin, Wisconsin)
STATE-GOVERNED, NOT LOCALLY SET, but SCOPE-LIMITED BY ROOF SLOPE -- read the trigger before pricing the job. Wis. Admin.

City of Brookfield, Wisconsin - Inspection Services & Zoning (City of Brookfield, Wisconsin)
STATE-SET AND SLOPE-CONDITIONED - read the trigger carefully, because it is narrower than the International Residential Code rule used in most other states. Wis. Admin. Code SPS 321.28(4) requires ice dam protection on shingled or shake roofs that extend over a heated area of the dwelling or an attached garage and that have a slope of 4 in 12 or less. It must be sheet metal or a product labelled as meeting ASTM D1970, and it must extend at least 30 inches up the roof slope from the roof edge and at least 12 inches up the roof slope beyond the inner face of the exterior wall. The trigger is the roof slope, not the climate zone, so a steeper Brookfield roof is not covered by the requirement at all - although the shingle manufacturer instructions may still call for it, and SPS 321.28(3)(a) makes those instructions binding for asphalt shingles. Brookfield adds nothing to this: the Brookfield Municipal Code was read and carries no ice barrier or ice dam provision anywhere. The Wisconsin uniform dwelling code sets these roofing rules statewide, but does not reach every house. It does not apply to a one- or two-family dwelling whose construction began before June 1, 1980, or to additions or alterations to one, unless the municipality has adopted chs. SPS 320 to 325 for that purpose — ask the building inspector before assuming it governs an older home.

Wisconsin has not resolved which of those two provisions governs a like-for-like tear-off, so confirm with the authority issuing the permit. On the age half of that, Brookfield has acted: Municipal Code section 15.04.050 applies chs. SPS 320 to 325 to additions, alterations, repairs and maintenance of one- and two-family dwellings "whether initially constructed before or after the effective date of the UDC," and section 15.04.070(B) repeats that the code reaches dwellings that would have been subject to it but for having been built before its effective date. So an older Brookfield house is not outside the state code.

City of Columbus - Building Inspector (City of Columbus, Wisconsin)
STATE-GOVERNED, NOT LOCALLY SET, but SCOPE-LIMITED BY ROOF SLOPE -- read the trigger before pricing the job. Wis. Admin. Code § SPS 321.28(4)(a) requires ice dam protection on shingled or shake roofs that extend over a heated area of the dwelling or an attached garage AND that have a slope of 4:12 or less; the protection must be sheet metal or a product labeled as meeting ASTM D1970. Wisconsin's UDC therefore does not impose the IRC's across-the-board cold-climate ice barrier on steeper roofs -- it is a Wisconsin-drafted rule, not an IRC clone. Extent, verbatim, SPS 321.28(4)(b): the ice dam protection "shall extend at least 30 inches up the roof slope from the roof edge and at least 12 inches up the roof slope beyond the inner face of the exterior wall." That is a different measurement convention from the IRC's 24-inches-inside-the-exterior-wall-line rule -- do not substitute IRC ice-barrier language on a Wisconsin job. Columbus may not impose a different ice-barrier rule on a one- or two-family dwelling (Wis. Stat. § 101.65(1c)). The mandate genuinely exists in Wisconsin code, but it is the 4:12-or-less slope condition described here, not the bare yes-or-no answer, that governs a given roof. SCOPE -- the same Uniform Dwelling Code limits that govern the layer rule govern this one, because Wis. Admin. Code SPS 320.05 exempts work from the code as a whole rather than from any single section. SPS 320.05(1) excludes dwellings whose construction commenced before the code's effective date, and additions or alterations to such dwellings, unless the municipality has adopted chs. SPS 320 to 325 for that purpose -- whether Columbus has done so is NOT established by this record. That date is June 1, 1980 for chs. SPS 320, 321, 323, 324 and 325 under SPS 320.03. Wis. Stat. 101.615 states December 1, 1978, but SPS 320.03 assigns that date to ch. SPS 322, the energy chapter; for a reroof, which is governed by chs. SPS 320 and 321, June 1, 1980 is the date that governs. SPS 320.05(3) further excludes "repairs or maintenance to dwellings or dwelling units," and SPS 320.07(61) defines "repair" to include "the replacement of existing fixtures, systems or equipment with the equivalent" fixture, system or equipment. On a dwelling built before 1980, confirm with the City of Columbus Building Inspector that the ice dam rule applies before pricing it in or out.
City of De Pere, Wisconsin - Building Inspection Division (City of De Pere, Wisconsin)
STATE-SET AND SLOPE-CONDITIONED - read the trigger carefully, because it is narrower than the International Residential Code rule used in most other states. Wis. Admin. Code SPS 321.28(4)(a) requires that "Shingled or shake roofs that extend over a heated area of a dwelling or attached garage and that have a slope of 4:12 or less shall be provided with ice dam protection in the form of sheet metal or a product labeled as meeting the requirements of ASTM D 1970." SPS 321.28(4)(b) sets the extent: the protection "shall extend at least 30 inches up the roof slope from the roof edge and at least 12 inches up the roof slope beyond the inner face of the exterior wall." The trigger is the roof slope, not the climate zone, so a steeper roof is not covered by the requirement at all - although the shingle manufacturer instructions may still call for it, and SPS 321.28(3)(a) makes those instructions binding for asphalt shingles. De Pere adds nothing to this: Chapter 54 of the Municipal Code was read in full and contains no ice barrier or ice dam provision. The Wisconsin uniform dwelling code sets these roofing rules statewide, but does not reach every house. It does not apply to a one- or two-family dwelling whose construction began before June 1, 1980, or to additions or alterations to one, unless the municipality has adopted chs. SPS 320 to 325 for that purpose - ask the building inspector before assuming it governs an older home. The code also states that it does not apply to repairs or maintenance, and it defines a repair to include replacing existing equipment with the equivalent, while a separate section regulates reroofing by name. Wisconsin has not resolved which of those two provisions governs a like-for-like tear-off, so confirm with the authority issuing the permit. De Pere has closed the older-house branch of that scope question, and it is one of very few Wisconsin municipalities that also spells out what an older house is excused from. Municipal Code section 54-3(c), headed Applicability, provides that "The Wisconsin Administrative Codes, as adopted in this chapter, are intended to apply to additions and alterations to one-family and two-family dwellings, including existing one-family and two-family dwellings, which were built prior to June 1, 1980 (effective adoption date of the uniform dwelling code), detached garages, accessory buildings, as well as new construction." Section 54-3(f)(3) then lists the conditions that are "exempt from compliance with the uniform dwelling code" in a pre-June-1-1980 house, and the four it names are stairways rebuilt in the same stairwell, ceiling heights of not less than six feet ten inches, habitable areas above the second floor served by a single exit, and unaltered windows below the egress size. NONE of the four is a roof provision, so the roofing standards reach an older De Pere house the same way they reach a new one.

City of Dodgeville - Building Inspection (City of Dodgeville, Wisconsin)
STATE-GOVERNED, NOT LOCALLY SET, but SCOPE-LIMITED BY ROOF SLOPE -- read the trigger before pricing the job. Wis. Admin. Code § SPS 321.28(4)(a) requires ice dam protection on shingled or shake roofs that extend over a heated area of the dwelling or an attached garage AND that have a slope of 4:12 or less; the protection must be sheet metal or a product labeled as meeting ASTM D1970. Wisconsin's UDC therefore does not impose the IRC's across-the-board cold-climate ice barrier on steeper roofs -- it is a Wisconsin-drafted rule, not an IRC clone.

City of Eau Claire, Wisconsin - Department of Community Development, Inspection Services Division (City of Eau Claire, Wisconsin)
STATE-SET AND SLOPE-CONDITIONED - read the trigger carefully, because it is narrower than the International Residential Code rule most other states use. The Wisconsin uniform dwelling code at SPS 321.28(4) requires that "Shingled or shake roofs that extend over a heated area of a dwelling or attached garage and that have a slope of 4:12 or less shall be provided with ice dam protection in the form of sheet metal or a product labeled as meeting the requirements of ASTM D 1970," and that "The ice dam protection shall extend at least 30 inches up the roof slope from the roof edge and at least 12 inches up the roof slope beyond the inner face of the exterior wall." Three conditions therefore have to be met before the requirement bites: the roof is shingled or shake, it extends over a heated area of the dwelling or an attached garage, and its slope is 4:12 or less. Wisconsin's trigger is the roof slope, not the climate zone, so a steeper roof in Eau Claire is not covered by this rule regardless of local snowfall. Two practical cautions. The shingle manufacturer's own installation instructions may still call for an ice barrier, and both the state code at SPS 321.28(3)(a) and the City's own building code at section 16.04.170 A make the manufacturer's instructions binding. And Wisconsin's 30 inches up the slope from the roof edge and 12 inches beyond the inner face of the exterior wall is a different measurement from the International Residential Code's 24 inches inside the exterior wall line, so do not substitute IRC ice-barrier language here. Eau Claire adds no ice-barrier rule of its own: Title 16 of the Municipal Code was searched in full and contains no ice dam or ice barrier provision. The Wisconsin uniform dwelling code sets these roofing rules statewide, but does not reach every house. It does not apply to a one- or two-family dwelling whose construction began before June 1, 1980, or to additions or alterations to one, unless the municipality has adopted chs. SPS 320 to 325 for that purpose — ask the building inspector before assuming it governs an older home. The code also states that it does not apply to repairs or maintenance, and it defines a repair to include replacing existing equipment with the equivalent, while a separate section regulates reroofing by name. Wisconsin has not resolved which of those two provisions governs a like-for-like tear-off, so confirm with the authority issuing the permit. On the first of those two points Eau Claire has acted, which sets it apart from most Wisconsin municipalities. Municipal Code section 16.04.180 adopts the state dwelling code, under its former chapter numbers COMM 20 to 25, "to apply to buildings, additions and alterations thereto, used as one- and two-family dwellings constructed prior to June 1, 1980 and to any accessory building or other buildings or structures not included within the scope of another adopted code." So the age of the house does not put an Eau Claire job outside the state code. That same section adds a list of City requirements on top of the state code for those older houses and states that "some may be more and some less stringent than the requirements of the Uniform Dwelling Code" and that where they conflict with the adopted code the City requirements apply, so on a pre-1980 house check the City list as well as the state one.
City of Fitchburg, Wisconsin - Building Inspection Department (City of Fitchburg, Wisconsin)
STATE-SET AND SLOPE-CONDITIONED - read the trigger carefully, because it is narrower than the International Residential Code rule used in most other states. Wis. Admin. Code SPS 321.28(4)(a) requires that "Shingled or shake roofs that extend over a heated area of a dwelling or attached garage and that have a slope of 4:12 or less shall be provided with ice dam protection in the form of sheet metal or a product labeled as meeting the requirements of ASTM D 1970." SPS 321.28(4)(b) sets the extent: the protection "shall extend at least 30 inches up the roof slope from the roof edge and at least 12 inches up the roof slope beyond the inner face of the exterior wall." The trigger is the roof slope, not the climate zone or a design temperature, so a roof steeper than 4:12 is not covered by the requirement at all - although the shingle manufacturer's instructions may still call for it, and SPS 321.28(3)(a)3. makes those instructions binding for asphalt shingles. Fitchburg adds nothing to this - Chapter 35 of the Municipal Code was read in full and contains no ice barrier or ice dam provision. AND THE SCOPE QUESTION THAT HANGS OVER MOST WISCONSIN REROOFS IS CLOSED HERE, BY NUMBER, IN THE ADOPTING SECTION ITSELF. Statewide, SPS 320.05(1) takes dwellings begun before the code took effect on June 1, 1980, and additions or alterations to them, outside the uniform dwelling code, and SPS 320.05(3) takes "repairs or maintenance" outside it as well - which matters because SPS 320.07(61) defines a repair to include "the replacement of existing fixtures, systems or equipment with the equivalent fixture, system or equipment." Fitchburg has excepted both of those exemptions by number. Municipal Code Sec. 35-77, "Adoption of state codes by reference," adopts at item (2) "Wis. Admin. Code SPS 320-325, Uniform Dwelling Code, except Wis. Admin. Code SPS 320.05(1), 320.05 (3) and 320.05(5)." So neither the age of the house nor the argument that a like-for-like tear-off is a repair takes a job here outside the dwelling code. That is unusual - most Wisconsin municipalities adopt the code without touching those two exemptions, and the roofer is left to ask the inspector which side of the line the job falls on.
City of Fond du Lac, Wisconsin - Community Development Department, Inspection Division (City of Fond du Lac, Wisconsin)
Required on shingled or shake roofs that extend over a heated area of the dwelling or an attached garage and that have a slope of 4:12 or less. The protection must be sheet metal or a product labeled as meeting the requirements of ASTM D1970, and it shall extend at least 30 inches up the roof slope from the roof edge and at least 12 inches up the roof slope beyond the inner face of the exterior wall. Wisconsin's trigger is the roof slope, not the climate zone, so this is materially narrower than the International Residential Code's ice-barrier rule: a steeper Fond du Lac roof is not caught by it, even though the city gets the ice-dam winters that make one worthwhile. Wisconsin also measures the extent differently from the IRC, so do not substitute IRC ice-barrier language on a Fond du Lac job. The shingle manufacturer's own installation instructions may still require an ice barrier on a steeper roof, and the state code makes those instructions binding for asphalt shingles. Fond du Lac has not added a local ice-barrier requirement of its own: its building code carries no ice or ice-barrier provision anywhere in the building article. The Wisconsin uniform dwelling code sets these roofing rules statewide, but does not reach every house. It does not apply to a one- or two-family dwelling whose construction began before June 1, 1980, or to additions or alterations to one, unless the municipality has adopted chs. SPS 320 to 325 for that purpose - ask the building inspector before assuming it governs an older home. The code also states that it does not apply to repairs or maintenance, and it defines a repair to include replacing existing equipment with the equivalent, while a separate section regulates reroofing by name. Wisconsin has not resolved which of those two provisions governs a like-for-like tear-off, so confirm with the authority issuing the permit. In Fond du Lac the first of those two branches is answered by the City's own building code rather than left open. Chapter 255, section 255-2A(1)(a) of the Fond du Lac municipal code adopts chs. SPS 320 through 325 of the Wisconsin Administrative Code and incorporates them into the City's building article by reference, and section 255-2C then provides that every alteration or repair to any part of any existing building shall be made to conform to the requirements of that article for new buildings, except if technically infeasible. So the City has extended these state construction standards to work on existing buildings, including dwellings older than June 1, 1980. The technically-infeasible allowance is the Building Inspector's call on the particular house, so on an older Fond du Lac home confirm the point with the Inspection Division before pricing the work.
City of Fort Atkinson - Neighborhood and Building Services Department (City of Fort Atkinson, Wisconsin)
STATE-GOVERNED, NOT LOCALLY SET, but SCOPE-LIMITED BY ROOF SLOPE -- read the trigger before pricing the job. Wis. Admin. Code § SPS 321.28(4)(a) requires ice dam protection on shingled or shake roofs that extend over a heated area of the dwelling or an attached garage AND that have a slope of 4:12 or less; the protection must be sheet metal or a product labeled as meeting ASTM D1970. Wisconsin's UDC therefore does not impose the IRC's across-the-board cold-climate ice barrier on steeper roofs -- it is a Wisconsin-drafted rule, not an IRC clone. Extent, verbatim, SPS 321.28(4)(b): the ice dam protection "shall extend at least 30 inches up the roof slope from the roof edge and at least 12 inches up the roof slope beyond the inner face of the exterior wall." That is a different measurement convention from the IRC's 24-inches-inside-the-exterior-wall-line rule -- do not substitute IRC ice-barrier language on a Wisconsin job. Fort Atkinson may not impose a different ice-barrier rule on a one- or two-family dwelling (Wis. Stat. § 101.65(1c)). The mandate genuinely exists in Wisconsin code, but it is the 4:12-or-less slope condition described here, not the bare yes-or-no answer, that governs a given roof. SCOPE -- the same Uniform Dwelling Code limits that govern the layer rule govern this one, because Wis. Admin. Code SPS 320.05 exempts work from the code as a whole rather than from any single section. SPS 320.05(1) excludes dwellings whose construction commenced before the code's effective date, and additions or alterations to such dwellings, unless the municipality has adopted chs. SPS 320 to 325 for that purpose -- whether Fort Atkinson has done so is NOT established by this record. That date is June 1, 1980 for chs. SPS 320, 321, 323, 324 and 325 under SPS 320.03. Wis. Stat. 101.615 states December 1, 1978, but SPS 320.03 assigns that date to ch. SPS 322, the energy chapter; for a reroof, which is governed by chs. SPS 320 and 321, June 1, 1980 is the date that governs. SPS 320.05(3) further excludes "repairs or maintenance to dwellings or dwelling units," and SPS 320.07(61) defines "repair" to include "the replacement of existing fixtures, systems or equipment with the equivalent" fixture, system or equipment. On a dwelling built before 1980, confirm with the City of Fort Atkinson Neighborhood and Building Services Department that the ice dam rule applies before pricing it in or out.
City of Franklin, Wisconsin - Inspection Services Department (City of Franklin, Wisconsin)
STATE-SET AND SLOPE-CONDITIONED - read the trigger carefully, because it is narrower than the International Residential Code rule used in most other states. Wis. Admin. Code SPS 321.28(4)(a) requires that shingled or shake roofs that extend over a heated area of a dwelling or attached garage and that have a slope of 4:12 or less be provided with ice dam protection "in the form of sheet metal or a product labeled as meeting the requirements of ASTM D 1970." SPS 321.28(4)(b) sets the extent: it "shall extend at least 30 inches up the roof slope from the roof edge and at least 12 inches up the roof slope beyond the inner face of the exterior wall." The trigger is the roof slope, not the climate zone, so a steeper Franklin roof is not covered by the requirement at all - although the shingle manufacturer's own instructions may still call for it, and SPS 321.28(3)(a) requires shingles to be installed in accordance with the manufacturer's recommendations. Note also that Wisconsin measures from the roof edge rather than from the exterior wall line the way the IRC does, so do not substitute IRC ice-barrier language on a Franklin job. Franklin adds nothing to this: Chapter 92 of the Municipal Code was read in full and contains no ice barrier or ice dam provision, and the regional Municipal Building Code the City adopts contains no ice dam provision either. The Wisconsin uniform dwelling code sets these roofing rules statewide, but does not reach every house. It does not apply to a one- or two-family dwelling whose construction began before June 1, 1980, or to additions or alterations to one, unless the municipality has adopted chs. SPS 320 to 325 for that purpose — ask the building inspector before assuming it governs an older home. The code also states that it does not apply to repairs or maintenance, and it defines a repair to include replacing existing equipment with the equivalent, while a separate section regulates reroofing by name. Wisconsin has not resolved which of those two provisions governs a like-for-like tear-off, so confirm with the authority issuing the permit. On the vintage half of that, Franklin has acted, through the regional Municipal Building Code it adopts rather than in its own building chapter: section 30.025 of that code applies the Uniform Dwelling Code "to alterations and additions to all one and two family dwellings constructed prior to the effective date of the Wisconsin Uniform Dwelling Code," and its Chapter VII is written for alterations and remodelling of dwellings built before June 1, 1980. So an older Franklin house is not outside the state code.
City of Glendale - Building Inspection Department (City of Glendale, Wisconsin)

City of Green Bay, Wisconsin - Department of Community & Economic Development, Inspection Division (Building Permits & Inspections) (City of Green Bay, Wisconsin)
STATE-GOVERNED, NOT CITY-SET, but SCOPE-LIMITED BY ROOF SLOPE -- read the trigger before pricing the job. Wis. Admin. Code § SPS 321.28(4)(a) requires ice dam protection on shingled or shake roofs that extend over a heated area of the dwelling or an attached garage AND that have a slope of 4:12 or less; the protection must be sheet metal or a product labeled as meeting ASTM D1970. Wisconsin's UDC therefore does not impose the IRC's across-the-board cold-climate ice barrier on steeper roofs -- it is a Wisconsin-drafted rule, not an IRC clone. Extent, verbatim, SPS 321.28(4)(b): the ice dam protection "shall extend at least 30 inches up the roof slope from the roof edge and at least 12 inches up the roof slope beyond the inner face of the exterior wall." That is a different measurement convention from the IRC's "24 inches inside the exterior wall line" -- do not substitute IRC ice-barrier language on a Wisconsin job. Green Bay may not impose a different ice-barrier rule on a one- or two-family dwelling (Wis. Stat. § 101.65(1c)). The mandate genuinely exists in Wisconsin code, but it is the 4:12-or-less slope condition described here, not the bare yes-or-no answer, that governs a given roof.

City of Greenfield, Wisconsin - Inspection Services (City of Greenfield, Wisconsin)
STATE-SET AND SLOPE-CONDITIONED, NOT CLIMATE-ZONE-CONDITIONED. Wis. Admin. Code SPS 321.28(4)(a) requires that "Shingled or shake roofs that extend over a heated area of a dwelling or attached garage and that have a slope of 4:12 or less shall be provided with ice dam protection in the form of sheet metal or a product labeled as meeting the requirements of ASTM D 1970." SPS 321.28(4)(b) sets the extent: it "shall extend at least 30 inches up the roof slope from the roof edge and at least 12 inches up the roof slope beyond the inner face of the exterior wall." The trigger is roof slope, not climate zone, so a steeper Greenfield roof is not covered by this requirement at all - although the shingle manufacturer's own installation instructions may still call for it, since SPS 321.28(3)(a) requires shingles to be installed in accordance with the manufacturer's recommendations. Wisconsin measures from the roof edge rather than from the exterior wall line the way the IRC does, so do not substitute IRC ice-barrier language on a Greenfield job. Greenfield adds nothing of its own to this: Chapter 15 of the Municipal Code was read in full and contains no ice barrier or ice dam provision, and the regional Wisconsin Uniform Building Code the City adopts at section 15.045 contains none either. On the vintage question, Greenfield has acted, through Municipal Code section 15.04(3): "Notwithstanding SPS 320.05, the scope also includes the construction and inspection of alterations and additions to one- and two-family dwellings built before June 1, 1980." So an older Greenfield house is not outside the state code the way it might be in a municipality without that extension. Separately, SPS 320.05(3) exempts repairs and maintenance, and SPS 320.07(61) defines a repair broadly enough to include like-for-like replacement, while SPS 321.28 regulates reroofing and ice-dam protection by name; Wisconsin has not resolved which provision governs a like-for-like tear-off, and this record does not adjudicate it.
City of Hartford - Building Inspection Office (City of Hartford, Wisconsin)
STATE-GOVERNED, NOT LOCALLY SET, but SCOPE-LIMITED BY ROOF SLOPE -- read the trigger before pricing the job. Wis. Admin. Code § SPS 321.28(4)(a) requires ice dam protection on shingled or shake roofs that extend over a heated area of the dwelling or an attached garage AND that have a slope of 4:12 or less; the protection must be sheet metal or a product labeled as meeting ASTM D1970. Wisconsin's UDC therefore does not impose the IRC's across-the-board cold-climate ice barrier on steeper roofs -- it is a Wisconsin-drafted rule, not an IRC clone. Extent, verbatim, SPS 321.28(4)(b): the ice dam protection "shall extend at least 30 inches up the roof slope from the roof edge and at least 12 inches up the roof slope beyond the inner face of the exterior wall." That is a different measurement convention from the IRC's 24-inches-inside-the-exterior-wall-line rule -- do not substitute IRC ice-barrier language on a Wisconsin job. Hartford may not impose a different ice-barrier rule on a one- or two-family dwelling (Wis. Stat. § 101.65(1c)). The mandate genuinely exists in Wisconsin code, but it is the 4:12-or-less slope condition described here, not the bare yes-or-no answer, that governs a given roof. SCOPE -- the same Uniform Dwelling Code limits that govern the layer rule govern this one, because Wis. Admin. Code SPS 320.05 exempts work from the code as a whole rather than from any single section. SPS 320.05(1) excludes dwellings whose construction commenced before the code's effective date, and additions or alterations to such dwellings, unless the municipality has adopted chs. SPS 320 to 325 for that purpose -- whether Hartford has done so is NOT established by this record. That date is June 1, 1980 for chs. SPS 320, 321, 323, 324 and 325 under SPS 320.03. Wis. Stat. 101.615 states December 1, 1978, but SPS 320.03 assigns that date to ch. SPS 322, the energy chapter; for a reroof, which is governed by chs. SPS 320 and 321, June 1, 1980 is the date that governs. SPS 320.05(3) further excludes "repairs or maintenance to dwellings or dwelling units," and SPS 320.07(61) defines "repair" to include "the replacement of existing fixtures, systems or equipment with the equivalent" fixture, system or equipment. On a dwelling built before 1980, confirm with the City of Hartford Building Inspection Office that the ice dam rule applies before pricing it in or out.

City of Kenosha, Wisconsin - Department of City Inspections, Building Inspection Division (City of Kenosha, Wisconsin)
Required on shingled or shake roofs that extend over a heated area of the dwelling or an attached garage and that have a slope of 4:12 or less. It must be sheet metal or a product labelled as meeting ASTM D1970, and it must extend at least 30 inches up the roof slope from the roof edge and at least 12 inches up the roof slope beyond the inner face of the exterior wall. Wisconsin's trigger is the roof slope, not the climate zone, so it is narrower than the International Residential Code's ice barrier rule and a steeper roof is not covered by it; Wisconsin's measurement convention differs too, so do not substitute IRC ice barrier language on a Kenosha job. Kenosha adds nothing here - Chapter IX of the Code of General Ordinances was read in full and sets no ice barrier requirement of its own. The Wisconsin uniform dwelling code sets these roofing rules statewide, but does not reach every house. It does not apply to a one- or two-family dwelling whose construction began before June 1, 1980, or to additions or alterations to one, unless the municipality has adopted chs. SPS 320 to 325 for that purpose — ask the building inspector before assuming it governs an older home. The code also states that it does not apply to repairs or maintenance, and it defines a repair to include replacing existing equipment with the equivalent, while a separate section regulates reroofing by name. Wisconsin has not resolved which of those two provisions governs a like-for-like tear-off, so confirm with the authority issuing the permit. Kenosha answers the first of those questions in its own ordinance, and the answer is unusually direct. Code of General Ordinances Sec. 9.10 A, headed Application of State Uniform Dwelling Code to One- and Two-Family Dwellings, provides that "[t]he State Uniform Dwelling Code in effect on June 1, 1980, shall apply to all one and two family Dwellings, and shall also apply where Alterations and/or repairs in excess of fifty (50) percent of the value thereof are made thereto within any period of twelve (12) consecutive months," the value being taken as of the date the building permit is applied for and without deduction for damage caused by the catastrophe that made the repairs necessary. The same subsection then adds that where a portion of the dwelling is damaged or out of repair, or an alteration of a portion is sought, and the cost does not exceed fifty percent of the value, "the State Uniform Dwelling Code shall be applicable only to the portion of the Dwelling which is damaged, out of repair, or which is sought to be Altered." So the City applies the dwelling code to all one- and two-family dwellings rather than only to those built after June 1, 1980, and on a partial job it applies to the part being worked on. That is the City taking a position on the state code's age carve-out; it is not a position on the repair-versus-alteration question, which remains open.
City of La Crosse, Wisconsin - Department of Planning and Development, Building and Inspections (City of La Crosse, Wisconsin)
STATE-SET AND SLOPE-CONDITIONED - it is narrower than the International Residential Code ice-barrier rule, and the difference matters in western Wisconsin. Wis. Admin. Code SPS 321.28(4)(a) requires that shingled or shake roofs that extend over a heated area of a dwelling or attached garage and that have a slope of 4:12 or less shall be provided with ice dam protection in the form of sheet metal or a product labeled as meeting the requirements of ASTM D 1970. SPS 321.28(4)(b) sets the extent: the ice dam protection shall extend at least 30 inches up the roof slope from the roof edge and at least 12 inches up the roof slope beyond the inner face of the exterior wall. Three conditions therefore have to be met together - shingled or shake, over a heated area, and 4:12 or shallower - so on a steeper La Crosse roof the dwelling code itself imposes no ice barrier, even though the city sits in heavy snow and ice country. The shingle manufacturer's own installation instructions may still require one, and SPS 321.28(3)(a) makes those instructions binding for asphalt shingles. Wisconsin's 30 inches up the slope and 12 inches past the inner face of the exterior wall is also a different measurement convention from the IRC 24 inches inside the exterior wall line. The Wisconsin uniform dwelling code sets these roofing rules statewide, but does not reach every house. It does not apply to a one- or two-family dwelling whose construction began before June 1, 1980, or to additions or alterations to one, unless the municipality has adopted chs. SPS 320 to 325 for that purpose - ask the building inspector before assuming it governs an older home. The code also states that it does not apply to repairs or maintenance, and it defines a repair to include replacing existing equipment with the equivalent, while a separate section regulates reroofing by name. Wisconsin has not resolved which of those two provisions governs a like-for-like tear-off, so confirm with the authority issuing the permit. In La Crosse the first of those two questions is answered by the City itself. La Crosse Municipal Code section 103-64, headed Application to existing buildings, provides that the Wisconsin Uniform Dwelling Code shall also apply to a list of buildings and conditions, and its item (4), Roof coverings, reads: Whenever more than 25 percent of the roof covering of a building is replaced in any 12-month period, all roof coverings shall be in conformity with applicable sections of this chapter. Item (5) adds that any addition or alteration to a building, regardless of cost, shall be made in conformity with the chapter, and item (2) reaches an alteration or repair whose cost over the life of the structure exceeds 50 percent of the equalized value. So La Crosse has closed the pre-1980 gap for roof coverings by its own ordinance, and a reroof here that replaces more than a quarter of the roof in a year is expected to meet these rules on an older house as well as a new one.

City of Madison, Wisconsin - Department of Planning, Community & Economic Development, Building Inspection Division (City of Madison, Wisconsin)
STATE-GOVERNED, NOT CITY-SET, AND SLOPE-CONDITIONED - read the scope carefully, it is narrower than the IRC/Minnesota rule. Wis. Admin. Code s. SPS 321.28(4)(a) requires that shingled or shake roofs that extend over a heated area of a dwelling or attached garage AND that have a slope of 4:12 or less be provided with ice dam protection, in the form of sheet metal or a product labeled as meeting the requirements of ASTM D1970. SPS 321.28(4)(b) sets the extent: the ice dam protection "shall extend at least 30 inches up the roof slope from the roof edge and at least 12 inches up the roof slope beyond the inner face of the exterior wall." Two cautions for Madison work: (1) on roof areas steeper than 4:12, the Uniform Dwelling Code does not itself impose an ice-barrier requirement, so a steep-slope reroof may be code-compliant without one (shingle manufacturers' own installation instructions may still require it, and SPS 321.28(3)(a) requires asphalt shingles to be installed per the manufacturer's instructions); (2) Wisconsin's "30 inches up the slope from the roof edge and 12 inches beyond the inner face of the exterior wall" is a different measurement convention from the IRC's "24 inches inside the exterior wall line" - do not substitute IRC ice-barrier language on a Wisconsin job. SCOPE -- the same Uniform Dwelling Code limits that govern the layer rule govern this one, because Wis. Admin. Code SPS 320.05 exempts work from the code as a whole rather than from any single section.

City of Manitowoc, Wisconsin - Building Inspection (City of Manitowoc, Wisconsin)
STATE-SET AND SLOPE-CONDITIONED - read the trigger carefully, because it is narrower than the International Residential Code rule used in most other states. Wis. Admin. Code SPS 321.28(4)(a) requires that "Shingled or shake roofs that extend over a heated area of a dwelling or attached garage and that have a slope of 4:12 or less shall be provided with ice dam protection in the form of sheet metal or a product labeled as meeting the requirements of ASTM D 1970." SPS 321.28(4)(b) sets the extent: the protection "shall extend at least 30 inches up the roof slope from the roof edge and at least 12 inches up the roof slope beyond the inner face of the exterior wall." The trigger is the roof slope, not the climate zone, so a steeper roof is not covered by the requirement at all - although the shingle manufacturer instructions may still call for it, and SPS 321.28(3)(a) makes those instructions binding for asphalt shingles. Manitowoc adds nothing to this: Title 16 of the Municipal Code was read in full and contains no ice barrier or ice dam provision, and the City could not add one for a one- or two-family dwelling in any event, because Wisconsin bars a municipality from enforcing a dwelling ordinance that does not conform to the state code. The Wisconsin uniform dwelling code sets these roofing rules statewide, but does not reach every house. It does not apply to a one- or two-family dwelling whose construction began before June 1, 1980, or to additions or alterations to one, unless the municipality has adopted chs. SPS 320 to 325 for that purpose — ask the building inspector before assuming it governs an older home. The code also states that it does not apply to repairs or maintenance, and it defines a repair to include replacing existing equipment with the equivalent, while a separate section regulates reroofing by name. Wisconsin has not resolved which of those two provisions governs a like-for-like tear-off, so confirm with the authority issuing the permit. Manitowoc has not been shown to have taken that step: Title 16 of the Municipal Code, the building chapter, was read in full - all eighteen sections - and it contains no provision extending the Uniform Dwelling Code to dwellings built before June 1, 1980, and no reference to that date at all. Section 16.010(2) adopts chs. SPS 320 through 325 and future amendments without an existing-dwelling extension. Whether some other part of the City code does it is not established here, so ask Building Inspection on 920-686-6940 rather than assuming either way on an older house.

Code Section SPS 321.28(4)(a) requires ice dam protection on shingled or shake roofs that extend over a heated area of the dwelling or an attached garage AND that have a slope of 4:12 or less; the protection must be sheet metal or a product labeled as meeting ASTM D1970. Wisconsin's UDC therefore does not impose the IRC's across-the-board cold-climate ice barrier on steeper roofs. Extent, verbatim, SPS 321.28(4)(b): the ice dam protection "shall extend at least 30 inches up the roof slope from the roof edge and at least 12 inches up the roof slope beyond the inner face of the exterior wall." That is a different measurement convention from the IRC's "24 inches inside the exterior wall line" -- do not substitute IRC ice-barrier language on a Wisconsin job. Menasha may not impose a different ice-barrier rule for a dwelling within the Uniform Dwelling Code's reach (Wis. Stat. Section 101.65(1c)). SCOPE -- and this is one of the few Wisconsin records in this corpus where the pre-1980 scope question is resolved rather than open. Wis. Admin. Code SPS 320.05 exempts work from the Uniform Dwelling Code as a whole rather than section by section, and SPS 320.05(1) excludes dwellings built before the code's June 1, 1980 effective date (SPS 320.03) and additions or alterations to such dwellings -- UNLESS the municipality has adopted chs. SPS 320 to 325 for that purpose. Menasha has: City of Menasha Code of Ordinances Sec. 15-1-3(a) adopts the Uniform Dwelling Code by reference "to apply to all additions and remodeling of existing one (1) and two (2) family homes ... including those build[t] prior to June 1, 1980." So for an addition or remodeling project in Menasha, the ice-dam rule above applies regardless of the dwelling's age. Wis. Admin. Code SPS 320.05(3) separately exempts "repairs or maintenance," and SPS 320.07(61) defines "repair" broadly enough that whether ordinary re-roofing itself (as opposed to a remodeling project that happens to touch the roof) falls inside or outside Sec. 15-1-3's reach is not adjudicated by this record -- see roof_layer_limit for the same tension stated in full.
City of Menomonie - Building Inspection / Zoning (City of Menomonie, Wisconsin)
STATE-GOVERNED, NOT LOCALLY SET, but SCOPE-LIMITED BY ROOF SLOPE -- read the trigger before pricing the job. Wis. Admin. Code § SPS 321.28(4)(a) requires ice dam protection on shingled or shake roofs that extend over a heated area of the dwelling or an attached garage AND that have a slope of 4:12 or less; the protection must be sheet metal or a product labeled as meeting ASTM D1970. Wisconsin's UDC therefore does not impose the IRC's across-the-board cold-climate ice barrier on steeper roofs -- it is a Wisconsin-drafted rule, not an IRC clone. Extent, verbatim, SPS 321.28(4)(b): the ice dam protection "shall extend at least 30 inches up the roof slope from the roof edge and at least 12 inches up the roof slope beyond the inner face of the exterior wall." That is a different measurement convention from the IRC's 24-inches-inside-the-exterior-wall-line rule -- do not substitute IRC ice-barrier language on a Wisconsin job. Menomonie may not impose a different ice-barrier rule on a one- or two-family dwelling (Wis. Stat. § 101.65(1c)). The mandate genuinely exists in Wisconsin code, but it is the 4:12-or-less slope condition described here, not the bare yes-or-no answer, that governs a given roof. SCOPE -- the same Uniform Dwelling Code limits that govern the layer rule govern this one, because Wis. Admin. Code SPS 320.05 exempts work from the code as a whole rather than from any single section. SPS 320.05(1) excludes dwellings whose construction commenced before the code's effective date, and additions or alterations to such dwellings, unless the municipality has adopted chs. SPS 320 to 325 for that purpose -- whether Menomonie has done so is NOT established by this record. That date is June 1, 1980 for chs. SPS 320, 321, 323, 324 and 325 under SPS 320.03. Wis. Stat. 101.615 states December 1, 1978, but SPS 320.03 assigns that date to ch. SPS 322, the energy chapter; for a reroof, which is governed by chs. SPS 320 and 321, June 1, 1980 is the date that governs. SPS 320.05(3) further excludes "repairs or maintenance to dwellings or dwelling units," and SPS 320.07(61) defines "repair" to include "the replacement of existing fixtures, systems or equipment with the equivalent" fixture, system or equipment. On a dwelling built before 1980, confirm with the City of Menomonie Building Inspection / Zoning office that the ice dam rule applies before pricing it in or out.
City of Middleton, Wisconsin - Building Inspection (City of Middleton, Wisconsin)
STATE-SET AND SLOPE-CONDITIONED - read the trigger carefully, because it is narrower than the International Residential Code rule used in most other states. Wis. Admin. Code SPS 321.28(4)(a) requires that "Shingled or shake roofs that extend over a heated area of a dwelling or attached garage and that have a slope of 4:12 or less shall be provided with ice dam protection in the form of sheet metal or a product labeled as meeting the requirements of ASTM D 1970." SPS 321.28(4)(b) sets the extent: the protection "shall extend at least 30 inches up the roof slope from the roof edge and at least 12 inches up the roof slope beyond the inner face of the exterior wall." The trigger is the roof slope, not the climate zone, so a steeper roof is not covered by the requirement at all - although the shingle manufacturer instructions may still call for it, and SPS 321.28(3)(a) makes those instructions binding for asphalt shingles. Middleton adds nothing to this: Chapter 11 of the Municipal Code was read in full and contains no ice barrier or ice dam provision. The Wisconsin uniform dwelling code sets these roofing rules statewide, but does not reach every house. It does not apply to a one- or two-family dwelling whose construction began before June 1, 1980, or to additions or alterations to one, unless the municipality has adopted chs. SPS 320 to 325 for that purpose - ask the building inspector before assuming it governs an older home. The code also states that it does not apply to repairs or maintenance, and it defines a repair to include replacing existing equipment with the equivalent, while a separate section regulates reroofing by name. Wisconsin has not resolved which of those two provisions governs a like-for-like tear-off, so confirm with the authority issuing the permit. MIDDLETON HAS ANSWERED THAT SCOPE QUESTION MORE DIRECTLY THAN ANY OTHER WISCONSIN MUNICIPALITY IN THIS DIRECTORY, AND A ROOFER SHOULD READ IT IN THE CITY OWN WORDS. Municipal Code Section 11.01(3) adopts a list of state administrative codes by reference and says of that list: "This Section shall apply to all additions and alterations to existing structures, except as noted below". Item (c) of the list is the dwelling code, and it is adopted in these terms: "Uniform Dwelling, Chapters SPS 320-25, Wisconsin Administrative Code [excepting therefrom Chapters SPS 320.05 (1), (3) and (5)]." Those are the exemption provisions themselves - (1) is the pre-June-1980 dwelling carve-out and (3) is the repairs and maintenance carve-out - so the City has adopted the dwelling standards while excepting the very subsections that would keep older houses and repair work outside them. As a matter of the Middleton code, then, neither the age of the house nor the characterisation of a reroof as a repair takes the job outside what the City enforces. This record reports what the City enacted and does not adjudicate how that interacts with the state statute; that is a question for the Building Inspection Department on 608-821-8370. Middleton also carries the roof-covering percentage rule that turns up across Wisconsin building chapters, at Section 11.01(4)(d): "Every alteration or repair to any structural part or portion of any existing building shall, when deemed necessary in the opinion of the Building Inspector, be made to conform to the requirements in this Code for new work, and not more than twenty-five (25) percent of any roof covering shall be replaced in any period of twelve (12) months unless the entire roof covering is made to conform with the requirements of this Code for new buildings." On a partial reroof that is the sentence to price against.
City of Milwaukee, Wisconsin - Department of Neighborhood Services (DNS) (City of Milwaukee, Wisconsin)
Governed statewide, not set by Milwaukee, and slope-conditioned. Wis. Admin. Code SPS 321.28(4)(a) requires ice dam protection on shingled or shake roofs that extend over a heated area of a dwelling or attached garage AND that have a slope of 4:12 or less; the protection must be sheet metal or a product labeled as meeting ASTM D1970. SPS 321.28(4)(b) sets the extent: the protection must extend at least 30 inches up the roof slope from the roof edge and at least 12 inches up the roof slope beyond the inner face of the exterior wall. On roofs steeper than 4:12 the Uniform Dwelling Code does not itself require an ice barrier. SCOPE -- the same Uniform Dwelling Code limits that govern the layer rule govern this one, because Wis. Admin. Code SPS 320.05 exempts work from the code as a whole rather than from any single section. SPS 320.05(1) excludes dwellings whose construction commenced before the code's effective date, and additions or alterations to such dwellings, unless the municipality has adopted chs. SPS 320 to 325 for that purpose -- whether Milwaukee has done so is NOT established by this record. That date is June 1, 1980 for chs. SPS 320, 321, 323, 324 and 325 under SPS 320.03. Wis. Stat. 101.615 states December 1, 1978, but SPS 320.03 assigns that date to ch. SPS 322, the energy chapter; for a reroof, which is governed by chs. SPS 320 and 321, June 1, 1980 is the date that governs. SPS 320.05(3) further excludes "repairs or maintenance to dwellings or dwelling units," and SPS 320.07(61) defines "repair" to include "the replacement of existing fixtures, systems or equipment with the equivalent" fixture, system or equipment. On a dwelling built before 1980, confirm with the City of Milwaukee Development Center that the ice dam rule applies before pricing it in or out.

City of Muskego, Wisconsin - Building Inspection (City of Muskego, Wisconsin)
STATE-SET AND SLOPE-CONDITIONED - read the trigger carefully, because it is narrower than the International Residential Code rule used in most other states. Wis. Admin. Code SPS 321.28(4)(a) requires that "Shingled or shake roofs that extend over a heated area of a dwelling or attached garage and that have a slope of 4:12 or less shall be provided with ice dam protection in the form of sheet metal or a product labeled as meeting the requirements of ASTM D 1970." SPS 321.28(4)(b) sets the extent: the protection "shall extend at least 30 inches up the roof slope from the roof edge and at least 12 inches up the roof slope beyond the inner face of the exterior wall." The trigger is the roof slope, not the climate zone, so a steeper roof is not covered by the requirement at all - although the shingle manufacturer instructions may still call for it, and SPS 321.28(3)(a) makes those instructions binding for asphalt shingles. Muskego adds nothing to this: Chapter 164 Article I of the Municipal Code was read in full and contains no ice barrier or ice dam provision. The Wisconsin uniform dwelling code sets these roofing rules statewide, but does not reach every house. It does not apply to a one- or two-family dwelling whose construction began before June 1, 1980, or to additions or alterations to one, unless the municipality has adopted chs. SPS 320 to 325 for that purpose - ask the building inspector before assuming it governs an older home. The code also states that it does not apply to repairs or maintenance, and it defines a repair to include replacing existing equipment with the equivalent, while a separate section regulates reroofing by name. Wisconsin has not resolved which of those two provisions governs a like-for-like tear-off, so confirm with the authority issuing the permit. Muskego has closed the older-house branch of that scope question, and it did it in an unusual way that a roofer should see in the City's own words rather than in a summary. Municipal Code section 164-3B provides that "The Wisconsin Uniform Dwelling Code, Chs. SPS 320 through 325, Wis. Adm. Code, inclusive, and all amendments thereto and the Wisconsin Uniform Building Code are hereby made a part of this code by reference and shall apply to all one- and two-family dwellings and alterations and additions thereto," with no cut-off by the age of the house, and then adds: "For purposes of this code, the Wisconsin Uniform Building Code shall apply to alterations and additions to all one- and two-family dwellings constructed prior to the effective date of the Wisconsin Uniform Dwelling Code." Both sentences are reproduced here as enacted, and which body of rules the second one points to on a particular older house is a question for the Building Inspector, not for this record. Section 164-3C(3)(d) then answers the roofing side of it by name: "Roof coverings. Whenever more than 25% of the roof covering of a building is replaced in any twelve-month period, all roof covering shall be in conformity with applicable sections of this code." So on any reroof past a quarter of the roof, the City's code is engaged whatever the age of the house.
City of Neenah, Wisconsin - Inspections Division (City of Neenah, Wisconsin)
STATE-SET AND SLOPE-CONDITIONED - read the trigger carefully, because it is narrower than the International Residential Code rule used in most other states. Wis. Admin. Code SPS 321.28(4)(a) requires that "Shingled or shake roofs that extend over a heated area of a dwelling or attached garage and that have a slope of 4:12 or less shall be provided with ice dam protection in the form of sheet metal or a product labeled as meeting the requirements of ASTM D 1970." SPS 321.28(4)(b) sets the extent: the protection "shall extend at least 30 inches up the roof slope from the roof edge and at least 12 inches up the roof slope beyond the inner face of the exterior wall." The trigger is the roof slope, not the climate zone, so a steeper roof is not covered by the requirement at all - although the shingle manufacturer instructions may still call for it, and SPS 321.28(3)(a) makes those instructions binding for asphalt shingles. Neenah adds nothing to this: Chapter 21 of the Municipal Code was read in full and contains no ice barrier or ice dam provision. The Wisconsin uniform dwelling code sets these roofing rules statewide, but does not reach every house. It does not apply to a one- or two-family dwelling whose construction began before June 1, 1980, or to additions or alterations to one, unless the municipality has adopted chs. SPS 320 to 325 for that purpose — ask the building inspector before assuming it governs an older home. The code also states that it does not apply to repairs or maintenance, and it defines a repair to include replacing existing equipment with the equivalent, while a separate section regulates reroofing by name. Wisconsin has not resolved which of those two provisions governs a like-for-like tear-off, so confirm with the authority issuing the permit. Neenah has closed the first of those two branches, and unusually plainly. Municipal Code section 21-33(a), headed Application, provides that "The Uniform Dwelling Code SPS 321—325, and all changes, is hereby adopted by reference to apply to all additions and remodeling of existing one- and two-family homes and any new or remodeled garage and/or storage shed, with the following exceptions." Section 21-23(3), headed Existing buildings, points the same way, providing at (3)c. that "Additions and alterations, regardless of cost, made to an existing building shall comply with the requirements of this code." So the age of the house does not put a Neenah job outside the state standards. One wrinkle worth noticing rather than glossing: section 21-33(a) names chs. SPS 321 to 325 while section 21-22 adopts "SPS 320-325, Uniform Dwelling Code" - the two sections list the chapters differently, and ch. SPS 320 is the chapter that carries the code's own scope and definitions. Both are reproduced here as printed.
City of New Berlin, Wisconsin - Department of Community Development, Inspection Services Division (City of New Berlin, Wisconsin)
STATE-GOVERNED, NOT CITY-SET, AND SLOPE-CONDITIONED -- it is narrower than the International Residential Code rule and narrower than most roofers expect. Wis. Admin. Code SPS 321.28(4)(a) requires that shingled or shake roofs that extend over a heated area of a dwelling or attached garage and that have a slope of 4:12 or less be provided with ice dam protection in the form of sheet metal or a product labeled as meeting the requirements of ASTM D 1970. SPS 321.28(4)(b) sets the extent: the ice dam protection shall extend at least 30 inches up the roof slope from the roof edge and at least 12 inches up the roof slope beyond the inner face of the exterior wall. Three conditions all have to be met -- shingled or shake, over a heated area, and 4:12 or shallower -- so on a steeper New Berlin roof the uniform dwelling code imposes no ice barrier of its own, though the shingle manufacturer's own installation instructions may still require one and SPS 321.28(3)(a) makes those instructions binding for asphalt shingles. Wisconsin's measurement convention also differs from the IRC's 24 inches inside the exterior wall line, so do not substitute IRC ice-barrier language on a Wisconsin job. New Berlin adopts these chapters by reference at Municipal Code Sec. 80-2.A and its own code adds nothing on ice barriers. SCOPE -- The Wisconsin uniform dwelling code sets these roofing rules statewide, but does not reach every house. It does not apply to a one- or two-family dwelling whose construction began before June 1, 1980, or to additions or alterations to one, unless the municipality has adopted chs. SPS 320 to 325 for that purpose — ask the building inspector before assuming it governs an older home. The code also states that it does not apply to repairs or maintenance, and it defines a repair to include replacing existing equipment with the equivalent, while a separate section regulates reroofing by name. Wisconsin has not resolved which of those two provisions governs a like-for-like tear-off, so confirm with the authority issuing the permit. Whether New Berlin has adopted chs. SPS 320 to 325 for additions and alterations to existing dwellings is not established by this record; its building chapter adopts the chapters against their state effective dates and says nothing about existing dwellings.
City of New London - Community Development Department (Building/Zoning) (City of New London, Wisconsin)
STATE-GOVERNED, NOT LOCALLY SET, but SCOPE-LIMITED BY ROOF SLOPE -- read the trigger before pricing the job. Wis. Admin. Code § SPS 321.28(4)(a) requires ice dam protection on shingled or shake roofs that extend over a heated area of the dwelling or an attached garage AND that have a slope of 4:12 or less; the protection must be sheet metal or a product labeled as meeting ASTM D1970. Wisconsin's UDC therefore does not impose the IRC's across-the-board cold-climate ice barrier on steeper roofs -- it is a Wisconsin-drafted rule, not an IRC clone. Extent, verbatim, SPS 321.28(4)(b): the ice dam protection "shall extend at least 30 inches up the roof slope from the roof edge and at least 12 inches up the roof slope beyond the inner face of the exterior wall." That is a different measurement convention from the IRC's 24-inches-inside-the-exterior-wall-line rule -- do not substitute IRC ice-barrier language on a Wisconsin job.

Stat. 101.615 states December 1, 1978, but SPS 320.03 assigns that date to ch. SPS 322, the energy chapter; for a reroof, which is governed by chs. SPS 320 and 321, June 1, 1980 is the date that governs. SPS 320.05(3) further excludes "repairs or maintenance to dwellings or dwelling units," and SPS 320.07(61) defines "repair" to include "the replacement of existing fixtures, systems or equipment with the equivalent" fixture, system or equipment. On a dwelling built before 1980, confirm with the City of New London Community Development Department that the ice dam rule applies before pricing it in or out.

SPS 320.05(1) excludes dwellings whose construction commenced before the code's effective date, and additions or alterations to such dwellings, unless the municipality has adopted chs. SPS 320 to 325 for that purpose -- whether New Richmond has done so is NOT established by this record. That date is June 1, 1980 for chs. SPS 320, 321, 323, 324 and 325 under SPS 320.03. Wis. Stat. 101.615 states December 1, 1978, but SPS 320.03 assigns that date to ch. SPS 322, the energy chapter; for a reroof, which is governed by chs. SPS 320 and 321, June 1, 1980 is the date that governs. SPS 320.05(3) further excludes "repairs or maintenance to dwellings or dwelling units," and SPS 320.07(61) defines "repair" to include "the replacement of existing fixtures, systems or equipment with the equivalent" fixture, system or equipment. On a dwelling built before 1980, confirm with the City of New Richmond Building Inspections Department that the ice dam rule applies before pricing it in or out.
City of Oak Creek, Wisconsin - Inspection Services Department (City of Oak Creek, Wisconsin)
STATE-SET AND SLOPE-CONDITIONED - the trigger is the roof slope, not the climate zone. Wis. Admin. Code SPS 321.28(4)(a) requires that shingled or shake roofs that extend over a heated area of a dwelling or attached garage and that have a slope of 4:12 or less be provided with ice dam protection "in the form of sheet metal or a product labeled as meeting the requirements of ASTM D 1970." SPS 321.28(4)(b) sets the extent: it "shall extend at least 30 inches up the roof slope from the roof edge and at least 12 inches up the roof slope beyond the inner face of the exterior wall." A steeper Oak Creek roof is not covered by the requirement at all, although the shingle manufacturer's own instructions may still call for it - SPS 321.28(3)(a) requires shingles to be installed in accordance with the manufacturer's recommendations. Wisconsin measures from the roof edge rather than from the exterior wall line the way the IRC does, so do not substitute IRC ice-barrier language on an Oak Creek job. Oak Creek adds nothing to this: the City's Municipal Code Chapter 15 was read in full, all 50 pages, and contains no ice barrier or ice dam provision.
City of Oconomowoc, Wisconsin - Building Inspection (City of Oconomowoc, Wisconsin)
STATE-SET AND SLOPE-CONDITIONED - read the trigger carefully, because it is narrower than the International Residential Code rule used in most other states. Wis. Admin. Code SPS 321.28(4)(a) requires that "Shingled or shake roofs that extend over a heated area of a dwelling or attached garage and that have a slope of 4:12 or less shall be provided with ice dam protection in the form of sheet metal or a product labeled as meeting the requirements of ASTM D 1970." SPS 321.28(4)(b) sets the extent: the protection "shall extend at least 30 inches up the roof slope from the roof edge and at least 12 inches up the roof slope beyond the inner face of the exterior wall." The trigger is the roof slope, not the climate zone or a design temperature, so a roof steeper than 4:12 is not covered by the requirement at all - although the shingle manufacturer's instructions may still call for it, and SPS 321.28(3)(a)3. makes those instructions binding for asphalt shingles. Oconomowoc adds nothing to this - Chapter 14 of the Municipal Code was read in full and contains no ice barrier or ice dam provision. ONE SCOPE POINT THAT APPLIES TO EVERY WISCONSIN REROOF AND IS NOT SETTLED. The uniform dwelling code sets these roofing rules statewide, but it does not reach every house and it may not reach every job. SPS 320.05(1) provides that the code does not apply to dwellings "the construction of which was commenced prior to the effective date of this code, or to additions or alterations to such dwellings" - the code took effect June 1, 1980, and the enabling statute, Wis. Stat. 101.615, draws the line differently again, at a dwelling "the initial construction of which was commenced on or after December 1, 1978." Both dates are reported here because the statute and the rule state the cut-off differently. SPS 320.05(3) separately provides that the code does not apply "to repairs or maintenance to dwellings or dwelling units," and SPS 320.07(61) defines a repair to include "the replacement of existing fixtures, systems or equipment with the equivalent fixture, system or equipment," which is a fair description of a like-for-like tear-off. Against that, SPS 321.28(6) regulates reroofing by name, and SPS 320.04(2) applies the whole code to alterations of a dwelling it covers. Wisconsin has not resolved that tension, and this record does not resolve it either. Ask the building inspector which side of it your job falls on before pricing the work. A municipality may also adopt chs. SPS 320 to 325 to reach additions and alterations to older dwellings, which closes half the question locally. OCONOMOWOC IS THE ONE JURISDICTION IN THIS DIRECTORY THAT WRITES THAT VINTAGE LINE INTO ITS OWN ORDINANCE, AND IT USES A THIRD DATE. Municipal Code Section 14.101(3) defines a dwelling, for the purposes of the section that adopts and enforces the uniform dwelling code, as "Any building, the initial construction of which is commenced on or after the effective date of this section, which contains one- or 2-dwelling units," and Section 14.101(6)(a) attaches the permit requirement to "No one- or 2-family dwellings of which initial construction shall be commenced after May 29, 1980." That is a THIRD date for the same idea: the state rule SPS 320.05(1) turns on the code effective date of June 1, 1980, the enabling statute Wis. Stat. 101.615 on initial construction commenced on or after December 1, 1978, and this section on May 29, 1980. The same section also defines an alteration as "A substantial change or modification other than an addition or minor repair to a dwelling or systems involved within a dwelling." WHAT THIS RECORD DOES NOT DO IS DECIDE WHAT FOLLOWS FOR AN OLDER HOUSE. The City charges a residential roofing permit fee without any vintage qualifier on its published fee schedule, and Chapter 14 publishes no exempt-work list, so the practical position and the literal words of Section 14.101(6)(a) are not obviously the same. Ask the Building Inspection Division before assuming either answer on a house built before 1980.
City of Oconto - Building Inspection (City of Oconto, Wisconsin)
STATE-GOVERNED, NOT LOCALLY SET, but SCOPE-LIMITED BY ROOF SLOPE -- read the trigger before pricing the job. Wis. Admin. Code § SPS 321.28(4)(a) requires ice dam protection on shingled or shake roofs that extend over a heated area of the dwelling or an attached garage AND that have a slope of 4:12 or less; the protection must be sheet metal or a product labeled as meeting ASTM D1970. Wisconsin's UDC therefore does not impose the IRC's across-the-board cold-climate ice barrier on steeper roofs -- it is a Wisconsin-drafted rule, not an IRC clone. Extent, verbatim, SPS 321.28(4)(b): the ice dam protection "shall extend at least 30 inches up the roof slope from the roof edge and at least 12 inches up the roof slope beyond the inner face of the exterior wall." That is a different measurement convention from the IRC's 24-inches-inside-the-exterior-wall-line rule -- do not substitute IRC ice-barrier language on a Wisconsin job. Oconto may not impose a different ice-barrier rule on a one- or two-family dwelling (Wis. Stat. § 101.65(1c)). The mandate genuinely exists in Wisconsin code, but it is the 4:12-or-less slope condition described here, not the bare yes-or-no answer, that governs a given roof.

City of Oshkosh, Wisconsin - Inspection Services Division (City of Oshkosh, Wisconsin)
STATE-SET AND SLOPE-CONDITIONED - this is narrower than the International Residential Code rule and the difference matters on most Oshkosh roofs. Wis. Admin. Code SPS 321.28(4)(a) requires that shingled or shake roofs that extend over a heated area of a dwelling or attached garage AND that have a slope of 4:12 or less be provided with ice dam protection, in the form of sheet metal or a product labeled as meeting the requirements of ASTM D 1970. SPS 321.28(4)(b) sets the extent: the protection "shall extend at least 30 inches up the roof slope from the roof edge and at least 12 inches up the roof slope beyond the inner face of the exterior wall." Two cautions. First, Wisconsin's trigger is the roof slope, not the climate zone, so on roof areas steeper than 4:12 the uniform dwelling code does not itself impose an ice barrier - the shingle manufacturer's installation instructions may still require one, and SPS 321.28(3)(a) makes those instructions binding for asphalt shingles. Second, the Wisconsin measurement convention is 30 inches up the slope from the roof edge and 12 inches beyond the inner face of the exterior wall, which is not the IRC's 24-inches-inside-the-exterior-wall-line convention; do not substitute IRC ice-barrier language on a Wisconsin job. The Wisconsin uniform dwelling code sets these roofing rules statewide, but does not reach every house. It does not apply to a one- or two-family dwelling whose construction began before June 1, 1980, or to additions or alterations to one, unless the municipality has adopted chs. SPS 320 to 325 for that purpose — ask the building inspector before assuming it governs an older home. The code also states that it does not apply to repairs or maintenance, and it defines a repair to include replacing existing equipment with the equivalent, while a separate section regulates reroofing by name. Wisconsin has not resolved which of those two provisions governs a like-for-like tear-off, so confirm with the authority issuing the permit.

City of Racine, Wisconsin - Department of City Development, Building Inspection Division (City of Racine, Wisconsin)
Required on shingled or shake roofs that extend over a heated area of the dwelling or an attached garage and that have a slope of 4:12 or less. It must be sheet metal or a product labeled as meeting the requirements of ASTM D 1970, and it must extend at least 30 inches up the roof slope from the roof edge and at least 12 inches up the roof slope beyond the inner face of the exterior wall. The Wisconsin trigger is the roof slope and not the climate zone, so it is a narrow rule: a roof steeper than 4:12 is not covered by it at all. Wisconsin also sets its own measurement, 30 inches up the slope from the roof edge and 12 inches past the inner face of the wall, so do not carry an ice-barrier detail over from an International Residential Code job. The Wisconsin uniform dwelling code sets these roofing rules statewide, but does not reach every house. It does not apply to a one- or two-family dwelling whose construction began before June 1, 1980, or to additions or alterations to one, unless the municipality has adopted chs. SPS 320 to 325 for that purpose — ask the building inspector before assuming it governs an older home. The code also states that it does not apply to repairs or maintenance, and it defines a repair to include replacing existing equipment with the equivalent, while a separate section regulates reroofing by name. Wisconsin has not resolved which of those two provisions governs a like-for-like tear-off, so confirm with the authority issuing the permit. Racine has adopted chs. SPS 320 to 325 by ordinance, at Municipal Code Sec. 18-30, but that section adopts the state codes for municipal enforcement without setting any scope of its own, and no provision anywhere in the city building chapter states that the dwelling code reaches additions or alterations to dwellings whose construction began before June 1, 1980. So whether Racine has closed that gap is not established, and it is worth asking Building Inspection before relying on the state rule for an older house. The city building code contains no ice barrier requirement of its own, but it does carry a low-slope eave condition that is easy to mistake for one. Sec. 18-311(b)(2) permits self-sealing or interlocking asphalt shingles at a slope down to 2 1/2 inches of rise per 12 inches of run only where "a double layer of 15-pound asphalt saturated felt underlayment is hot-mopped on the roof overhang and extends up to a point at least 24 inches inside of the exterior building wall." That is a felt underlayment condition attached to using shingles at low slope, not an ice and water membrane requirement.

That is a different measurement convention from the IRC's 24-inches-inside-the-exterior-wall-line rule -- do not substitute IRC ice-barrier language on a Wisconsin job. Shawano may not impose a different ice-barrier rule on a one- or two-family dwelling (Wis. Stat. § 101.65(1c)). The mandate genuinely exists in Wisconsin code, but it is the 4:12-or-less slope condition described here, not the bare yes-or-no answer, that governs a given roof. SCOPE -- the same Uniform Dwelling Code limits that govern the layer rule govern this one, because Wis. Admin. Code SPS 320.05 exempts work from the code as a whole rather than from any single section. SPS 320.05(1) excludes dwellings whose construction commenced before the code's effective date, and additions or alterations to such dwellings, unless the municipality has adopted chs. SPS 320 to 325 for that purpose -- whether Shawano has done so is NOT established by this record. That date is June 1, 1980 for chs. SPS 320, 321, 323, 324 and 325 under SPS 320.03. Wis. Stat. 101.615 states December 1, 1978, but SPS 320.03 assigns that date to ch. SPS 322, the energy chapter; for a reroof, which is governed by chs. SPS 320 and 321, June 1, 1980 is the date that governs. SPS 320.05(3) further excludes "repairs or maintenance to dwellings or dwelling units," and SPS 320.07(61) defines "repair" to include "the replacement of existing fixtures, systems or equipment with the equivalent" fixture, system or equipment. On a dwelling built before 1980, confirm with the City of Shawano Community Development Department's Building Inspection office that the ice dam rule applies before pricing it in or out.
City of Sheboygan Falls - Building Permits (City Hall) (City of Sheboygan Falls, Wisconsin)
STATE-GOVERNED, NOT LOCALLY SET, but SCOPE-LIMITED BY ROOF SLOPE -- read the trigger before pricing the job. Wis. Admin. Code § SPS 321.28(4)(a) requires ice dam protection on shingled or shake roofs that extend over a heated area of the dwelling or an attached garage AND that have a slope of 4:12 or less; the protection must be sheet metal or a product labeled as meeting ASTM D1970. Wisconsin's UDC therefore does not impose the IRC's across-the-board cold-climate ice barrier on steeper roofs -- it is a Wisconsin-drafted rule, not an IRC clone. Extent, verbatim, SPS 321.28(4)(b): the ice dam protection "shall extend at least 30 inches up the roof slope from the roof edge and at least 12 inches up the roof slope beyond the inner face of the exterior wall." That is a different measurement convention from the IRC's 24-inches-inside-the-exterior-wall-line rule -- do not substitute IRC ice-barrier language on a Wisconsin job. Sheboygan Falls may not impose a different ice-barrier rule on a one- or two-family dwelling (Wis. Stat. § 101.65(1c)). The mandate genuinely exists in Wisconsin code, but it is the 4:12-or-less slope condition described here, not the bare yes-or-no answer, that governs a given roof. SCOPE -- the same Uniform Dwelling Code limits that govern the layer rule govern this one, because Wis. Admin. Code SPS 320.05 exempts work from the code as a whole rather than from any single section.

City of Sheboygan, Wisconsin - Building Inspection Division (City of Sheboygan, Wisconsin)
REQUIRED, BUT ONLY ON LOW-SLOPE ROOFS - Wisconsin's trigger is the roof slope, not the climate zone, and that makes it narrower than the International Residential Code ice-barrier rule most other states use. The Wisconsin uniform dwelling code requires ice dam protection on shingled or shake roofs that extend over a heated area of a dwelling or an attached garage and that have a slope of 4:12 or less. It must be sheet metal or a product labelled as meeting the requirements of ASTM D1970, and it "shall extend at least 30 inches up the roof slope from the roof edge and at least 12 inches up the roof slope beyond the inner face of the exterior wall." Three cautions for Sheboygan work. On a roof steeper than 4:12 the dwelling code imposes no ice barrier of its own, so a steep-slope reroof can be code-compliant without one - but the shingle manufacturer's own installation instructions may still require it, and the dwelling code makes those instructions binding for asphalt shingles. The Wisconsin measurement convention (30 inches up the slope from the edge, and 12 inches beyond the inner face of the exterior wall) is not the IRC's 24-inches-inside-the-exterior-wall-line, so do not substitute IRC ice-barrier language on a Sheboygan job. And the City of Sheboygan adds no ice barrier requirement of its own; the state rule is the whole of the code obligation here. The Wisconsin uniform dwelling code sets these roofing rules statewide, but does not reach every house. It does not apply to a one- or two-family dwelling whose construction began before June 1, 1980, or to additions or alterations to one, unless the municipality has adopted chs. SPS 320 to 325 for that purpose — ask the building inspector before assuming it governs an older home. The code also states that it does not apply to repairs or maintenance, and it defines a repair to include replacing existing equipment with the equivalent, while a separate section regulates reroofing by name. Wisconsin has not resolved which of those two provisions governs a like-for-like tear-off, so confirm with the authority issuing the permit. On the first of those two points Sheboygan has acted, which sets it apart from most Wisconsin municipalities: Municipal Code section 12-21(b), Uniform dwelling code, adopts chs. SPS 320 to 325 by reference and applies them to all new and existing one- and two-family dwellings including alterations and additions to them. So the age of the house does not put a Sheboygan job outside the state code. The repair-versus-alteration question in the second half is a matter of state law and is not resolved by anything the City has enacted.
City of South Milwaukee, Wisconsin - Inspection Department (City of South Milwaukee, Wisconsin)
STATE-SET AND SLOPE-CONDITIONED - read the trigger carefully, because it is narrower than the International Residential Code rule used in most other states. Wis. Admin. Code SPS 321.28(4)(a) requires that "Shingled or shake roofs that extend over a heated area of a dwelling or attached garage and that have a slope of 4:12 or less shall be provided with ice dam protection in the form of sheet metal or a product labeled as meeting the requirements of ASTM D 1970." SPS 321.28(4)(b) sets the extent: the protection "shall extend at least 30 inches up the roof slope from the roof edge and at least 12 inches up the roof slope beyond the inner face of the exterior wall." The trigger is the roof slope, not the climate zone or a design temperature, so a roof steeper than 4:12 is not covered by the requirement at all - although the shingle manufacturer's instructions may still call for it, and SPS 321.28(3)(a)3. makes those instructions binding for asphalt shingles. South Milwaukee adds nothing to this - Chapter 16 of the Municipal Code was read in full and contains no ice barrier or ice dam provision. ONE SCOPE POINT THAT APPLIES TO EVERY WISCONSIN REROOF AND IS NOT SETTLED. The uniform dwelling code sets these roofing rules statewide, but it does not reach every house and it may not reach every job. SPS 320.05(1) provides that the code does not apply to dwellings "the construction of which was commenced prior to the effective date of this code, or to additions or alterations to such dwellings" - the code took effect June 1, 1980, and the enabling statute, Wis. Stat. 101.615, draws the line differently again, at a dwelling "the initial construction of which was commenced on or after December 1, 1978." Both dates are reported here because the statute and the rule state the cut-off differently. SPS 320.05(3) separately provides that the code does not apply "to repairs or maintenance to dwellings or dwelling units," and SPS 320.07(61) defines a repair to include "the replacement of existing fixtures, systems or equipment with the equivalent fixture, system or equipment," which is a fair description of a like-for-like tear-off. Against that, SPS 321.28(6) regulates reroofing by name, and SPS 320.04(2) applies the whole code to alterations of a dwelling it covers. Wisconsin has not resolved that tension, and this record does not resolve it either. Ask the building inspector which side of it your job falls on before pricing the work. A municipality may also adopt chs. SPS 320 to 325 to reach additions and alterations to older dwellings, which closes half the question locally.
City of Stevens Point, Wisconsin - Division of Inspection Services (City of Stevens Point, Wisconsin)
STATE-SET AND SLOPE-CONDITIONED - read the trigger carefully, because it is narrower than the International Residential Code rule used in most other states. Wis. Admin. Code SPS 321.28(4)(a) requires that "Shingled or shake roofs that extend over a heated area of a dwelling or attached garage and that have a slope of 4:12 or less shall be provided with ice dam protection in the form of sheet metal or a product labeled as meeting the requirements of ASTM D 1970." SPS 321.28(4)(b) sets the extent: the protection "shall extend at least 30 inches up the roof slope from the roof edge and at least 12 inches up the roof slope beyond the inner face of the exterior wall." The trigger is the roof slope, not the climate zone or a design temperature, so a roof steeper than 4:12 is not covered by the requirement at all - although the shingle manufacturer's instructions may still call for it, and SPS 321.28(3)(a)3. makes those instructions binding for asphalt shingles. Stevens Point adds nothing to the requirement itself - Chapter 30 of the Municipal Code was read in full and contains no ice barrier or ice dam provision - but its Section 30.01(5)(c) decides when the state standard attaches to an existing dwelling: more than 25 percent of the roof covering by area replaced in any 12-month period, which on a typical reroof is comfortably crossed.
City of Stoughton - Department of Planning and Development (City of Stoughton, Wisconsin)
STATE-GOVERNED, NOT LOCALLY SET, but SCOPE-LIMITED BY ROOF SLOPE -- read the trigger before pricing the job. Wis. Admin. Code § SPS 321.28(4)(a) requires ice dam protection on shingled or shake roofs that extend over a heated area of the dwelling or an attached garage AND that have a slope of 4:12 or less; the protection must be sheet metal or a product labeled as meeting ASTM D1970. Wisconsin's UDC therefore does not impose the IRC's across-the-board cold-climate ice barrier on steeper roofs -- it is a Wisconsin-drafted rule, not an IRC clone. Extent, verbatim, SPS 321.28(4)(b): the ice dam protection "shall extend at least 30 inches up the roof slope from the roof edge and at least 12 inches up the roof slope beyond the inner face of the exterior wall." That is a different measurement convention from the IRC's 24-inches-inside-the-exterior-wall-line rule -- do not substitute IRC ice-barrier language on a Wisconsin job. Stoughton may not impose a different ice-barrier rule on a one- or two-family dwelling (Wis. Stat. § 101.65(1c)). The mandate genuinely exists in Wisconsin code, but it is the 4:12-or-less slope condition described here, not the bare yes-or-no answer, that governs a given roof. SCOPE -- the same Uniform Dwelling Code limits that govern the layer rule govern this one, because Wis. Admin. Code SPS 320.05 exempts work from the code as a whole rather than from any single section. SPS 320.05(1) excludes dwellings whose construction commenced before the code's effective date, and additions or alterations to such dwellings, unless the municipality has adopted chs. SPS 320 to 325 for that purpose -- whether Stoughton has done so is NOT established by this record. That date is June 1, 1980 for chs. SPS 320, 321, 323, 324 and 325 under SPS 320.03. Wis. Stat. 101.615 states December 1, 1978, but SPS 320.03 assigns that date to ch. SPS 322, the energy chapter; for a reroof, which is governed by chs. SPS 320 and 321, June 1, 1980 is the date that governs. SPS 320.05(3) further excludes "repairs or maintenance to dwellings or dwelling units," and SPS 320.07(61) defines "repair" to include "the replacement of existing fixtures, systems or equipment with the equivalent" fixture, system or equipment. On a dwelling built before 1980, confirm with the City of Stoughton Department of Planning and Development that the ice dam rule applies before pricing it in or out.
City of Sun Prairie, Wisconsin - Building Inspection (City of Sun Prairie, Wisconsin)
STATE-SET AND SLOPE-CONDITIONED - read the trigger carefully, because it is narrower than the International Residential Code rule used in most other states. Wis. Admin. Code SPS 321.28(4)(a) requires that "Shingled or shake roofs that extend over a heated area of a dwelling or attached garage and that have a slope of 4:12 or less shall be provided with ice dam protection in the form of sheet metal or a product labeled as meeting the requirements of ASTM D 1970." SPS 321.28(4)(b) sets the extent: the protection "shall extend at least 30 inches up the roof slope from the roof edge and at least 12 inches up the roof slope beyond the inner face of the exterior wall." The trigger is the roof slope, not the climate zone, so a steeper roof is not covered by the requirement at all - although the shingle manufacturer instructions may still call for it, and SPS 321.28(3)(a) makes those instructions binding for asphalt shingles. Sun Prairie adds nothing to this: Chapter 15.04 of the Municipal Code was read in full and contains no ice barrier or ice dam provision. The Wisconsin uniform dwelling code sets these roofing rules statewide, but does not reach every house. It does not apply to a one- or two-family dwelling whose construction began before June 1, 1980, or to additions or alterations to one, unless the municipality has adopted chs. SPS 320 to 325 for that purpose — ask the building inspector before assuming it governs an older home. The code also states that it does not apply to repairs or maintenance, and it defines a repair to include replacing existing equipment with the equivalent, while a separate section regulates reroofing by name. Wisconsin has not resolved which of those two provisions governs a like-for-like tear-off, so confirm with the authority issuing the permit. Sun Prairie has closed the first of those two branches, and it is one of the very few Wisconsin municipalities whose ordinance reaches ROOFING BY NAME when it does so. Municipal Code section 15.04.030(B), headed Existing Buildings, provides that "The Wisconsin Uniform Dwelling Code shall also apply to buildings and conditions where," and lists among them at (B)(4): "Roof coverings. Whenever more than twenty-five percent (25%) of the roof covering of a building is replaced in any twelve-month period, all roof covering shall be in conformity with applicable sections of this chapter." Subsection (B)(5) adds "Any addition, or alteration, regardless of cost, made to a building, shall be made in conformity with applicable sections of this chapter." So on any reroof past a quarter of the roof, the state standards apply in Sun Prairie whatever the age of the house. One tension in the chapter is worth seeing rather than glossing: the definitions at section 15.04.030(C) define a Dwelling as "Any building, the initial construction of which is commenced on or after the effective date of this chapter, which contains one or two dwelling units, or ... An existing structure, or that part of an existing structure, which is used or intended to be used as a one- or two-family dwelling." Both limbs are published here as written; on an older house, confirm scope with Building Inspection on 608-825-1184.
City of Superior, Wisconsin - Building Inspection Division (City of Superior, Wisconsin)
STATE-SET AND SLOPE-CONDITIONED - read the trigger carefully, because it is narrower than the International Residential Code rule used in most other states. Wis. Admin. Code SPS 321.28(4)(a) requires that "Shingled or shake roofs that extend over a heated area of a dwelling or attached garage and that have a slope of 4:12 or less shall be provided with ice dam protection in the form of sheet metal or a product labeled as meeting the requirements of ASTM D 1970." SPS 321.28(4)(b) sets the extent: the protection "shall extend at least 30 inches up the roof slope from the roof edge and at least 12 inches up the roof slope beyond the inner face of the exterior wall." The trigger is the roof slope, not the climate zone or a design temperature, so a roof steeper than 4:12 is not covered by the requirement at all - although the shingle manufacturer's instructions may still call for it, and SPS 321.28(3)(a)3. makes those instructions binding for asphalt shingles. Superior adds nothing to the requirement itself - Chapter 34 of the Municipal Code was read in full and contains no ice barrier or ice dam provision - but its Sec. 34-7(4) decides when the state standard attaches to an existing dwelling: more than 45 percent of the roof covering replaced in any 12-month period. Given the City position on Lake Superior, the slope test is the one to check on site rather than assumed away.

City of Watertown, Wisconsin - Building, Safety, & Zoning (City of Watertown, Wisconsin)
STATE-SET AND SLOPE-CONDITIONED - the trigger is roof slope, not climate zone, and it is narrower than the International Residential Code rule used in most other states. Wis. Admin. Code SPS 321.28(4)(a) requires that "Shingled or shake roofs that extend over a heated area of a dwelling or attached garage and that have a slope of 4:12 or less shall be provided with ice dam protection in the form of sheet metal or a product labeled as meeting the requirements of ASTM D 1970." SPS 321.28(4)(b) sets the extent: the protection "shall extend at least 30 inches up the roof slope from the roof edge and at least 12 inches up the roof slope beyond the inner face of the exterior wall." A roof steeper than 4:12 falls outside the literal requirement, although shingle manufacturer installation instructions - binding under SPS 321.28(3)(a) - may still call for it regardless of slope. Watertown adds nothing of its own: Chapter 253 of the Municipal Code was read in full, all 59 sections, and contains no ice dam or ice barrier provision. The Wisconsin Uniform Dwelling Code sets this rule statewide, and Watertown has affirmatively extended the code to additions and alterations of every existing one- and two-family dwelling - Municipal Code section 253-3(A)(3)(a) - so the age carve-out that limits the construction standards in some other Wisconsin cities does not limit them here. What is separately unresolved is whether a like-for-like reroof counts as an "alteration" the City's election reaches or a "repair" SPS 320.05(3) exempts from the code entirely; see the roof-layer-limit field for that unresolved question, which bears equally on this one.
City of Waukesha, Wisconsin - Department of Community Development, Building Inspection Division (City of Waukesha, Wisconsin)
STATE-SET AND SLOPE-CONDITIONED - read the trigger carefully, because it is narrower than the International Residential Code rule used in most other states. Wis. Admin. Code SPS 321.28(4) requires ice dam protection on shingled or shake roofs that extend over a heated area of the dwelling or an attached garage and that have a slope of 4 in 12 or less. It must be sheet metal or a product labelled as meeting ASTM D1970, and it must extend at least 30 inches up the roof slope from the roof edge and at least 12 inches up the roof slope beyond the inner face of the exterior wall. The trigger is the roof slope, not the climate zone, so a steeper Waukesha roof is not covered by the requirement at all - although the shingle manufacturer instructions may still call for it, and SPS 321.28(3)(a) makes those instructions binding for asphalt shingles. Waukesha adds nothing to this: Chapter 16 of the Municipal Code was read in full and contains no ice barrier or ice dam provision, and neither does any other chapter of the City code. The Wisconsin uniform dwelling code sets these roofing rules statewide, but does not reach every house. It does not apply to a one- or two-family dwelling whose construction began before June 1, 1980, or to additions or alterations to one, unless the municipality has adopted chs. SPS 320 to 325 for that purpose — ask the building inspector before assuming it governs an older home. The code also states that it does not apply to repairs or maintenance, and it defines a repair to include replacing existing equipment with the equivalent, while a separate section regulates reroofing by name. Wisconsin has not resolved which of those two provisions governs a like-for-like tear-off, so confirm with the authority issuing the permit. On the vintage half of that, Waukesha has acted: Municipal Code section 16.01(6)(b) applies chs. SPS 320 to 325 to "all new and existing one- and two-family dwellings," and adds only that state building permit seals are not required for permits on dwellings built before June 1, 1980. So an older Waukesha house is not outside the state code.

Wisconsin's UDC therefore does not impose the IRC's across-the-board cold-climate ice barrier on steeper roofs -- it is a Wisconsin-drafted rule, not an IRC clone. Extent, verbatim, SPS 321.28(4)(b): the ice dam protection "shall extend at least 30 inches up the roof slope from the roof edge and at least 12 inches up the roof slope beyond the inner face of the exterior wall." That is a different measurement convention from the IRC's "24 inches inside the exterior wall line" -- do not substitute IRC ice-barrier language on a Wisconsin job. West Allis may not impose a different ice-barrier rule on a one- or two-family dwelling (Wis. Stat. Section 101.65(1c)). The mandate genuinely exists in Wisconsin code, but it is the 4:12-or-less slope condition described here, not a bare yes-or-no answer, that governs a given roof. SCOPE -- the same Uniform Dwelling Code limits that govern the layer rule govern this one, because Wis. Admin. Code SPS 320.05 exempts work from the code as a whole rather than from any single section. SPS 320.05(1) excludes dwellings whose construction commenced before the code's effective date, and additions or alterations to such dwellings, unless the municipality has adopted chs. SPS 320 to 325 for that purpose -- whether West Allis has done so is NOT established by this record, because the municipal code section that would say so could not be opened this session. That date is June 1, 1980 for chs. SPS 320, 321, 323, 324 and 325 under SPS 320.03; Wis. Stat. 101.615 states December 1, 1978 for the subchapter as a whole -- report both. SPS 320.05(3) further excludes "repairs or maintenance to dwellings or dwelling units," and SPS 320.07(61) defines "repair" to include "the replacement of existing fixtures, systems or equipment with the equivalent" fixture, system or equipment. On a dwelling built before 1980, confirm with West Allis Building Inspection that the ice dam rule applies before pricing it in or out.
City of West Bend, Wisconsin - Division of Building Inspection (City of West Bend, Wisconsin)
STATE-SET AND SLOPE-CONDITIONED - read the trigger carefully, because it is narrower than the International Residential Code rule used in most other states. Wis. Admin. Code SPS 321.28(4)(a) requires that "Shingled or shake roofs that extend over a heated area of a dwelling or attached garage and that have a slope of 4:12 or less shall be provided with ice dam protection in the form of sheet metal or a product labeled as meeting the requirements of ASTM D 1970." SPS 321.28(4)(b) sets the extent: the protection "shall extend at least 30 inches up the roof slope from the roof edge and at least 12 inches up the roof slope beyond the inner face of the exterior wall." The trigger is the roof slope, not the climate zone, so a steeper roof is not covered by the requirement at all - although the shingle manufacturer instructions may still call for it, and SPS 321.28(3)(a) makes those instructions binding for asphalt shingles. West Bend adds nothing to this: Chapter 14 of the Municipal Code was read in full and contains no ice barrier or ice dam provision. The Wisconsin uniform dwelling code sets these roofing rules statewide, but does not reach every house. It does not apply to a one- or two-family dwelling whose construction began before June 1, 1980, or to additions or alterations to one, unless the municipality has adopted chs. SPS 320 to 325 for that purpose — ask the building inspector before assuming it governs an older home. The code also states that it does not apply to repairs or maintenance, and it defines a repair to include replacing existing equipment with the equivalent, while a separate section regulates reroofing by name. Wisconsin has not resolved which of those two provisions governs a like-for-like tear-off, so confirm with the authority issuing the permit. West Bend has NOT been shown to have taken that step for dwellings, and the way its ordinance is written makes that worth stating carefully rather than guessing. Municipal Code section 14.03(2) adopts chs. SPS 320 to 325 and then overrides one exemption in the state code by name: "Despite the provisions of SPS 320.05(4), SPS 320 to 325 shall apply to all accessory buildings in the City." Subsection (4) of that state section is the accessory-buildings exemption. The City says nothing about subsection (1), the pre-June-1980 dwellings exemption, or subsection (3), the repairs exemption. Chapter 14 was read in full, all of sections 14.01 to 14.27, and it contains no reference to June 1, 1980 and no other extension of the state code to existing dwellings. So on an older West Bend house, ask the Building Inspector on 262-335-5140 rather than assuming either way.

Town of Grand Chute, Wisconsin - Building Inspection (Town of Grand Chute, Wisconsin)
STATE-SET AND SLOPE-CONDITIONED - read the trigger carefully, because it is narrower than the International Residential Code rule used in most other states. Wis. Admin. Code SPS 321.28(4)(a) requires that "Shingled or shake roofs that extend over a heated area of a dwelling or attached garage and that have a slope of 4:12 or less shall be provided with ice dam protection in the form of sheet metal or a product labeled as meeting the requirements of ASTM D 1970." SPS 321.28(4)(b) sets the extent: the protection "shall extend at least 30 inches up the roof slope from the roof edge and at least 12 inches up the roof slope beyond the inner face of the exterior wall." The trigger is the roof slope, not the climate zone, so a steeper roof is not covered by the requirement at all - although the shingle manufacturer instructions may still call for it, and SPS 321.28(3)(a) makes those instructions binding for asphalt shingles. Grand Chute adds nothing to this: Chapter 220 and Chapter 317 of the Town Code were read in full and contain no ice barrier or ice dam provision. The Wisconsin uniform dwelling code sets these roofing rules statewide, but does not reach every house. It does not apply to a one- or two-family dwelling whose construction began before June 1, 1980, or to additions or alterations to one, unless the municipality has adopted chs. SPS 320 to 325 for that purpose - ask the building inspector before assuming it governs an older home. The code also states that it does not apply to repairs or maintenance, and it defines a repair to include replacing existing equipment with the equivalent, while a separate section regulates reroofing by name. Wisconsin has not resolved which of those two provisions governs a like-for-like tear-off, so confirm with the authority issuing the permit. GRAND CHUTE HAS CLOSED THE OLDER-HOUSE BRANCH OF THAT QUESTION, AND IT DID IT WITHOUT EVER NAMING A DATE. Town Code Section 220-28B(2)(a) provides: "The Uniform Dwelling Code is hereby adopted by reference as part of this article with respect to all additions or remodeling of existing dwellings." The adoption is written to reach existing dwellings as a class rather than dwellings built after a cut-off, so the age of the house does not take a Grand Chute job outside the Town-enforced dwelling standards. Section 220-28B(2)(b) extends the general requirements and applicable standards of the same code to residential accessory buildings and structures. Chapter 220 was read in full, all thirty-nine sections across both articles, and the year 1980 does not appear anywhere in it.

Town of Oneida - Building Inspector (Town of Oneida, Wisconsin)
STATE-GOVERNED, NOT LOCALLY SET, but SCOPE-LIMITED BY ROOF SLOPE -- read the trigger before pricing the job. Wis. Admin. Code § SPS 321.28(4)(a) requires ice dam protection on shingled or shake roofs that extend over a heated area of the dwelling or an attached garage AND that have a slope of 4:12 or less; the protection must be sheet metal or a product labeled as meeting ASTM D1970. Wisconsin's UDC therefore does not impose the IRC's across-the-board cold-climate ice barrier on steeper roofs -- it is a Wisconsin-drafted rule, not an IRC clone. Extent, verbatim, SPS 321.28(4)(b): the ice dam protection "shall extend at least 30 inches up the roof slope from the roof edge and at least 12 inches up the roof slope beyond the inner face of the exterior wall." That is a different measurement convention from the IRC's 24-inches-inside-the-exterior-wall-line rule -- do not substitute IRC ice-barrier language on a Wisconsin job. Oneida may not impose a different ice-barrier rule on a one- or two-family dwelling (Wis. Stat. § 101.65(1c)). The mandate genuinely exists in Wisconsin code, but it is the 4:12-or-less slope condition described here, not the bare yes-or-no answer, that governs a given roof.

Village of Caledonia, Wisconsin - Building Department (Village of Caledonia, Wisconsin)
STATE-SET AND SLOPE-CONDITIONED - read the trigger carefully, because it is narrower than the International Residential Code rule used in most other states. Wis. Admin. Code SPS 321.28(4)(a) requires that "Shingled or shake roofs that extend over a heated area of a dwelling or attached garage and that have a slope of 4:12 or less shall be provided with ice dam protection in the form of sheet metal or a product labeled as meeting the requirements of ASTM D 1970." SPS 321.28(4)(b) sets the extent: the protection "shall extend at least 30 inches up the roof slope from the roof edge and at least 12 inches up the roof slope beyond the inner face of the exterior wall." The trigger is the roof slope, not the climate zone, so a steeper roof is not covered by the requirement at all - although the shingle manufacturer instructions may still call for it, and SPS 321.28(3)(a) makes those instructions binding for asphalt shingles. Caledonia adds nothing to this: Title 15 of the Municipal Code was read in full and contains no ice barrier or ice dam provision. The Wisconsin uniform dwelling code sets these roofing rules statewide, but does not reach every house. It does not apply to a one- or two-family dwelling whose construction began before June 1, 1980, or to additions or alterations to one, unless the municipality has adopted chs. SPS 320 to 325 for that purpose - ask the building inspector before assuming it governs an older home. The code also states that it does not apply to repairs or maintenance, and it defines a repair to include replacing existing equipment with the equivalent, while a separate section regulates reroofing by name. Wisconsin has not resolved which of those two provisions governs a like-for-like tear-off, so confirm with the authority issuing the permit. CALEDONIA HAS CLOSED THAT GAP MORE PLAINLY THAN ALMOST ANY OTHER WISCONSIN MUNICIPALITY - IT NAMES THE STATE EXEMPTION AND OVERRIDES IT. Municipal Code section 15-1-3(b)(3)a. provides: "Notwithstanding Wis. Admin. Code SPS 320.05 or any other exemptions of the Uniform Dwelling Code, the scope of this ordinance also includes the construction and inspection of alterations and additions to one- and two-family dwellings built before June 1, 1980. Because such projects are not under state jurisdiction, petitions for variance and final appeals under Wis. Admin. Code SPS 320.19 and 320.21, respectively, shall be decided by the Zoning Board of Appeals." The same subsection extends the code to detached garages serving one- and two-family dwellings on the same footing. Section 15-1-4(d)(4) then answers the roofing side by name: "Roof Coverings. Whenever more than twenty-five percent (25%) of the roof covering of a building is replaced in any twelve (12) month period, all roof covering shall be in conformity with applicable Sections of this Code." So a reroof past a quarter of the roof is inside the code in Caledonia whatever the age of the house, and an older house that needs relief goes to the Village Zoning Board of Appeals rather than to the state. One internal tension is worth seeing rather than glossing: the older section 15-1-29, which is still on the books, states its purpose as jurisdiction over new dwellings and additions to existing ones, and adopts the dwelling code under its former chapter names. Section 15-1-3(b)(3) supplies the rule for that: "To the extent any provision of this Section conflicts with another section of the Municipal Code, the most restrictive provision shall apply."
Village of Combined Locks - Clerk's Office (Building Permits) (Village of Combined Locks, Wisconsin)
STATE-GOVERNED, NOT LOCALLY SET, but SCOPE-LIMITED BY ROOF SLOPE -- read the trigger before pricing the job. Wis. Admin. Code § SPS 321.28(4)(a) requires ice dam protection on shingled or shake roofs that extend over a heated area of the dwelling or an attached garage AND that have a slope of 4:12 or less; the protection must be sheet metal or a product labeled as meeting ASTM D1970. Wisconsin's UDC therefore does not impose the IRC's across-the-board cold-climate ice barrier on steeper roofs -- it is a Wisconsin-drafted rule, not an IRC clone. Extent, verbatim, SPS 321.28(4)(b): the ice dam protection "shall extend at least 30 inches up the roof slope from the roof edge and at least 12 inches up the roof slope beyond the inner face of the exterior wall." That is a different measurement convention from the IRC's 24-inches-inside-the-exterior-wall-line rule -- do not substitute IRC ice-barrier language on a Wisconsin job. Combined Locks may not impose a different ice-barrier rule on a one- or two-family dwelling (Wis. Stat. § 101.65(1c)). The mandate genuinely exists in Wisconsin code, but it is the 4:12-or-less slope condition described here, not the bare yes-or-no answer, that governs a given roof. SCOPE -- the same Uniform Dwelling Code limits that govern the layer rule govern this one, because Wis. Admin. Code SPS 320.05 exempts work from the code as a whole rather than from any single section.

SPS 320 to 325 for that purpose -- whether Combined Locks has done so is NOT established by this record. That date is June 1, 1980 for chs. SPS 320, 321, 323, 324 and 325 under SPS 320.03. Wis.

Village of Germantown, Wisconsin - Building Inspection Services (Village of Germantown, Wisconsin)
STATE-SET AND SLOPE-CONDITIONED - read the trigger carefully, because it is narrower than the International Residential Code rule used in most other states. Wis. Admin. Code SPS 321.28(4)(a) requires that "Shingled or shake roofs that extend over a heated area of a dwelling or attached garage and that have a slope of 4:12 or less shall be provided with ice dam protection in the form of sheet metal or a product labeled as meeting the requirements of ASTM D 1970." SPS 321.28(4)(b) sets the extent: the protection "shall extend at least 30 inches up the roof slope from the roof edge and at least 12 inches up the roof slope beyond the inner face of the exterior wall." The trigger is the roof slope, not the climate zone or a design temperature, so a roof steeper than 4:12 is not covered by the requirement at all - although the shingle manufacturer's instructions may still call for it, and SPS 321.28(3)(a)3. makes those instructions binding for asphalt shingles. Germantown adds nothing to this - Chapter 14 of the Village Code was read in full and contains no ice barrier or ice dam provision. AND GERMANTOWN HAS CLOSED THE OLDER-HOUSE HALF OF THE SCOPE QUESTION THAT HANGS OVER MOST WISCONSIN REROOFS, WITHOUT EVER NAMING A DATE. Statewide, SPS 320.05(1) provides that the uniform dwelling code does not apply to dwellings "the construction of which was commenced prior to the effective date of this code, or to additions or alterations to such dwellings" - the code took effect June 1, 1980, while the enabling statute, Wis. Stat. 101.615, draws the line at initial construction commenced on or after December 1, 1978. Both dates are reported because the statute and the rule state the cut-off differently. The same rule carries a note saying the chapters "may be adopted by a municipality to apply to any additions or alterations to existing dwellings," and that is exactly what Germantown has done. Village Code Section 14.07(2) adopts the code twice over: at (a) chs. SPS 320 to 326 "shall apply to all new one-family and 2-family dwellings and all additions to existing and new one-family and 2-family dwellings," and at (b) they "shall pertain to all remodeling or alterations in existing one-family and 2-family dwellings." Subsection (b) reaches existing dwellings as a class rather than dwellings built after a cut-off, so the age of the house does not take a Germantown job outside the Village-enforced dwelling standards. WHAT IS NOT CLOSED HERE IS THE OTHER HALF. SPS 320.05(3) provides that the code does not apply "to repairs or maintenance to dwellings or dwelling units," and SPS 320.07(61) defines a repair to include "the replacement of existing fixtures, systems or equipment with the equivalent fixture, system or equipment," which is a fair description of a like-for-like tear-off - while SPS 321.28(6) regulates reroofing by name. Germantown adopts the code for "remodeling or alterations" and does not except SPS 320.05(3), so whether a straight like-for-like reroof is an alteration or a repair is a question for the building inspector on the job. Ask before pricing the work.

Village of Hortonville - Building Inspector (Village of Hortonville, Wisconsin)
STATE-GOVERNED, NOT LOCALLY SET, but SCOPE-LIMITED BY ROOF SLOPE -- read the trigger before pricing the job. Wis. Admin. Code § SPS 321.28(4)(a) requires ice dam protection on shingled or shake roofs that extend over a heated area of the dwelling or an attached garage AND that have a slope of 4:12 or less; the protection must be sheet metal or a product labeled as meeting ASTM D1970. Wisconsin's UDC therefore does not impose the IRC's across-the-board cold-climate ice barrier on steeper roofs -- it is a Wisconsin-drafted rule, not an IRC clone. Extent, verbatim, SPS 321.28(4)(b): the ice dam protection "shall extend at least 30 inches up the roof slope from the roof edge and at least 12 inches up the roof slope beyond the inner face of the exterior wall." That is a different measurement convention from the IRC's 24-inches-inside-the-exterior-wall-line rule -- do not substitute IRC ice-barrier language on a Wisconsin job. Hortonville may not impose a different ice-barrier rule on a one- or two-family dwelling (Wis. Stat. § 101.65(1c)). The mandate genuinely exists in Wisconsin code, but it is the 4:12-or-less slope condition described here, not the bare yes-or-no answer, that governs a given roof. SCOPE -- the same Uniform Dwelling Code limits that govern the layer rule govern this one, because Wis. Admin. Code SPS 320.05 exempts work from the code as a whole rather than from any single section. SPS 320.05(1) excludes dwellings whose construction commenced before the code's effective date, and additions or alterations to such dwellings, unless the municipality has adopted chs. SPS 320 to 325 for that purpose -- whether Hortonville has done so is NOT established by this record. That date is June 1, 1980 for chs. SPS 320, 321, 323, 324 and 325 under SPS 320.03. Wis. Stat. 101.615 states December 1, 1978, but SPS 320.03 assigns that date to ch. SPS 322, the energy chapter; for a reroof, which is governed by chs.

Village of Howard, Wisconsin - Building Inspection (Village of Howard, Wisconsin)
STATE-SET AND SLOPE-CONDITIONED - read the trigger carefully, because it is narrower than the International Residential Code rule used in most other states. Wis. Admin. Code SPS 321.28(4)(a) requires that "Shingled or shake roofs that extend over a heated area of a dwelling or attached garage and that have a slope of 4:12 or less shall be provided with ice dam protection in the form of sheet metal or a product labeled as meeting the requirements of ASTM D 1970." SPS 321.28(4)(b) sets the extent: the protection "shall extend at least 30 inches up the roof slope from the roof edge and at least 12 inches up the roof slope beyond the inner face of the exterior wall." The trigger is the roof slope, not the climate zone or a design temperature, so a roof steeper than 4:12 is not covered by the requirement at all - although the shingle manufacturer's instructions may still call for it, and SPS 321.28(3)(a)3. makes those instructions binding for asphalt shingles. Howard adds nothing to the requirement - Chapter 40 of the Village Code was read in full and contains no ice barrier or ice dam provision - but it does more than most Wisconsin municipalities to make sure the state requirement reaches the job. AND THE SCOPE QUESTION THAT HANGS OVER MOST WISCONSIN REROOFS IS CLOSED HERE, BY NUMBER, IN THE ADOPTING SECTION ITSELF. Statewide, SPS 320.05(1) takes dwellings begun before the code took effect on June 1, 1980, and additions or alterations to them, outside the uniform dwelling code, and SPS 320.05(3) takes "repairs or maintenance" outside it as well - which matters because SPS 320.07(61) defines a repair to include "the replacement of existing fixtures, systems or equipment with the equivalent fixture, system or equipment." Howard has excepted those carve-outs by number and even annotated them. Village Code Section 40-64, "State codes adopted," adopts at item (3) the "Uniform Dwelling Code, Wis. Admin. Code chs. SPS 320-325, with the exception of: a. Wis. Admin. Code SPS 320.05(1), additions and alterations to existing buildings built prior to June 1, 1980. b. Wis. Admin. Code SPS 320.05(3), repairs or maintenance to dwellings. c. Wis. Admin. Code SPS 320.05(4), accessory buildings with the exception of the braced wall line requirements of Wis. Admin. Code SPS 321.25(8) and (9) and the energy conservation requirements of Wis. Admin. Code SPS 322." So neither the age of the house nor the argument that a like-for-like tear-off is a repair takes a job here outside the dwelling code. That is unusual - most Wisconsin municipalities adopt the code without touching those two exemptions, and the roofer is left to ask the inspector which side of the line the job falls on. So the slope test governs on a Howard house of any vintage, on a job that needs no permit and will not be inspected. Green Bay area snow loads make the 4:12 line worth measuring rather than eyeballing.

Village of Menomonee Falls, Wisconsin - Building Inspection (Village of Menomonee Falls, Wisconsin)
STATE-SET AND SLOPE-CONDITIONED - read the trigger carefully, because it is narrower than the International Residential Code rule used in most other states. Wis. Admin. Code SPS 321.28(4)(a) requires that "Shingled or shake roofs that extend over a heated area of a dwelling or attached garage and that have a slope of 4:12 or less shall be provided with ice dam protection in the form of sheet metal or a product labeled as meeting the requirements of ASTM D 1970." SPS 321.28(4)(b) sets the extent: the protection "shall extend at least 30 inches up the roof slope from the roof edge and at least 12 inches up the roof slope beyond the inner face of the exterior wall." The trigger is the roof slope, not the climate zone, so a steeper roof is not covered by the requirement at all - although the shingle manufacturer instructions may still call for it, and SPS 321.28(3)(a) makes those instructions binding for asphalt shingles. Menomonee Falls adds nothing to this: Chapter 18 of the Municipal Code was read in full and contains no ice barrier or ice dam provision, and the Village could not add one for a one- or two-family dwelling in any event, because Wisconsin bars a municipality from enforcing a dwelling ordinance that does not conform to the state code. The Wisconsin uniform dwelling code sets these roofing rules statewide, but does not reach every house. It does not apply to a one- or two-family dwelling whose construction began before June 1, 1980, or to additions or alterations to one, unless the municipality has adopted chs. SPS 320 to 325 for that purpose — ask the building inspector before assuming it governs an older home. The code also states that it does not apply to repairs or maintenance, and it defines a repair to include replacing existing equipment with the equivalent, while a separate section regulates reroofing by name. Wisconsin has not resolved which of those two provisions governs a like-for-like tear-off, so confirm with the authority issuing the permit. On the vintage half of that, Menomonee Falls has acted: Municipal Code section 18-100 expands the Uniform Dwelling Code standards to additions, alterations and major equipment replacements on one- and two-family dwellings built before June 1, 1980, so an older Menomonee Falls house is not outside the state code.

Wisconsin's UDC therefore does not impose the IRC's across-the-board cold-climate ice barrier on steeper roofs -- it is a Wisconsin-drafted rule, not an IRC clone. Extent, verbatim, SPS 321.28(4)(b): the ice dam protection "shall extend at least 30 inches up the roof slope from the roof edge and at least 12 inches up the roof slope beyond the inner face of the exterior wall." That is a different measurement convention from the IRC's 24-inches-inside-the-exterior-wall-line rule -- do not substitute IRC ice-barrier language on a Wisconsin job. Mount Horeb may not impose a different ice-barrier rule on a one- or two-family dwelling (Wis. Stat. § 101.65(1c)). The mandate genuinely exists in Wisconsin code, but it is the 4:12-or-less slope condition described here, not the bare yes-or-no answer, that governs a given roof. SCOPE -- the same Uniform Dwelling Code limits that govern the layer rule govern this one, because Wis. Admin. Code SPS 320.05 exempts work from the code as a whole rather than from any single section. SPS 320.05(1) excludes dwellings whose construction commenced before the code's effective date, and additions or alterations to such dwellings, unless the municipality has adopted chs. SPS 320 to 325 for that purpose -- whether Mount Horeb has done so is NOT established by this record. That date is June 1, 1980 for chs. SPS 320, 321, 323, 324 and 325 under SPS 320.03. Wis. Stat. 101.615 states December 1, 1978, but SPS 320.03 assigns that date to ch. SPS 322, the energy chapter; for a reroof, which is governed by chs. SPS 320 and 321, June 1, 1980 is the date that governs. SPS 320.05(3) further excludes "repairs or maintenance to dwellings or dwelling units," and SPS 320.07(61) defines "repair" to include "the replacement of existing fixtures, systems or equipment with the equivalent" fixture, system or equipment. On a dwelling built before 1980, confirm with the Village of Mount Horeb Building Inspection office that the ice dam rule applies before pricing it in or out.
Village of Mount Pleasant, Wisconsin - Building Inspection (Village of Mount Pleasant, Wisconsin)
STATE-SET AND SLOPE-CONDITIONED - read the trigger carefully, because it is narrower than the International Residential Code rule used in most other states. Wis. Admin. Code SPS 321.28(4)(a) requires that "Shingled or shake roofs that extend over a heated area of a dwelling or attached garage and that have a slope of 4:12 or less shall be provided with ice dam protection in the form of sheet metal or a product labeled as meeting the requirements of ASTM D 1970." SPS 321.28(4)(b) sets the extent: the protection "shall extend at least 30 inches up the roof slope from the roof edge and at least 12 inches up the roof slope beyond the inner face of the exterior wall." The trigger is the roof slope, not the climate zone, so a steeper roof is not covered by the requirement at all - although the shingle manufacturer instructions may still call for it, and SPS 321.28(3)(a) makes those instructions binding for asphalt shingles. Mount Pleasant adds nothing to this: Article I of Chapter 14 of the Municipal Code was read in full and contains no ice barrier or ice dam provision. The Wisconsin uniform dwelling code sets these roofing rules statewide, but does not reach every house. It does not apply to a one- or two-family dwelling whose construction began before June 1, 1980, or to additions or alterations to one, unless the municipality has adopted chs. SPS 320 to 325 for that purpose — ask the building inspector before assuming it governs an older home. The code also states that it does not apply to repairs or maintenance, and it defines a repair to include replacing existing equipment with the equivalent, while a separate section regulates reroofing by name. Wisconsin has not resolved which of those two provisions governs a like-for-like tear-off, so confirm with the authority issuing the permit. Mount Pleasant has closed the first of those two branches, and it is one of the few Wisconsin municipalities that names the date outright. Municipal Code section 14-9(a) provides that "The UDC shall apply to alterations and additions, where technically feasible, for one- and two-family dwellings built prior to June 1, 1980," and section 14-9(a)(1) adds that "When existing conditions prohibit alterations that comply with the UDC, the Building Inspector shall approve proposed alternatives." So an older Mount Pleasant house is inside the state code, subject to a technical-feasibility judgment the Building Inspector makes. Section 14-6 points the same way from the other end, applying the Mount Pleasant Building Code to "new construction, additions, or alterations" of one- and two-family dwellings with no vintage limit of its own.

Wisconsin has not resolved which of those two provisions governs a like-for-like tear-off, so confirm with the authority issuing the permit. Pleasant Prairie has closed the older-house branch of that scope question, and it did it without naming a date at all - by scoping its building code to the work rather than to the vintage of the house. Municipal Code section 370-4, headed Scope, provides: "This chapter pertains to the construction, addition, alteration, repair, maintenance, demolition, relocation, or change of use of all new or existing residential, commercial, agricultural, recreational or related accessory buildings and structures within the Village of Pleasant Prairie." Section 370-7C then adopts the Wisconsin Uniform Dwelling Code, chs. SPS 320 to 325, and all amendments thereto, into that chapter, and section 370-9 requires that "No person shall perform any work except in full compliance with the requirements of this chapter." So the Village code reaches repair and maintenance of an existing house by name, with no cut-off by the year it was built. Note the honest limit of that: the Village has said what its own chapter reaches. Whether the state exemptions still bite on a particular older job is a question for the Building Inspection Department on 262-694-9304, and this record does not answer it.

The mandate genuinely exists in Wisconsin code, but it is the 4:12-or-less slope condition described here, not the bare yes-or-no answer, that governs a given roof.

Village of Twin Lakes - Building and Zoning Department (Village of Twin Lakes, Wisconsin)
STATE-GOVERNED, NOT LOCALLY SET, but SCOPE-LIMITED BY ROOF SLOPE -- read the trigger before pricing the job. Wis. Admin. Code § SPS 321.28(4)(a) requires ice dam protection on shingled or shake roofs that extend over a heated area of the dwelling or an attached garage AND that have a slope of 4:12 or less; the protection must be sheet metal or a product labeled as meeting ASTM D1970. Wisconsin's UDC therefore does not impose the IRC's across-the-board cold-climate ice barrier on steeper roofs -- it is a Wisconsin-drafted rule, not an IRC clone.

Ice barrier required — Wyoming (8)
Campbell County Building Division (Campbell County, Wyoming (unincorporated area))
Chapter 4, Section 1.6.I, Climatic and Geographical Design Criteria (the table that Section 4.A.2 substitutes for IRC Table R301.2), states plainly: "Ice Barrier Roof Underlayment Requirements: Yes/ Required." That designation triggers the base IRC ice-barrier extent rule at Section R905.1.2. The same table lists Weathering as "Severe."
City of Cheyenne - Building Permitting & Licensing Division (City of Cheyenne, Wyoming)
City Code Section 15.10.020(L) amends IRC Table R301.2(1), Climatic and Geographic Design Criteria, to state "ICE BARRIER UNDER LAYMENT REQUIRED: YES" for the City of Cheyenne. That designation triggers IRC Section R905.1.2: the ice barrier must extend from the lowest edges of all roof surfaces to a point not less than 24 inches inside the exterior wall line of the building. The same amended table lists WEATHERING: Severe.
City of Laramie - Building Department (Code Administration) (City of Laramie, Wyoming)
Laramie Municipal Code Section 15.24.010.A.3 amends IRC Table R301.2 to state "Ice shield underlayment required = Yes" for the City of Laramie, alongside "Weathering = Severe" and a winter design temperature of -10 degrees F. The City's Informational Bulletin #30 confirms: "Ice barrier is required," citing IRC Section R905.1.2.
City of Riverton - Community Development Department, Building Permits & Inspections (City of Riverton, Wyoming)
Municipal Code Section 15.04.010 amends Table R301.2 (Climatic and Geographic Design Criteria) to state, in the column "Ice Barrier Underlayment Required": "Yes." Section 15.04.040, Local design criteria and loadings, independently restates the identical table with the same "Yes" entry. The same table lists Weathering as "Severe" and Frost line depth as "30 inches."
City of Rock Springs - Building Inspections & Permits (City of Rock Springs, Wyoming)
City Code Article 7-1, Section 7-108.4, Amendment (d) amends IRC Section R-905.1.2: "In areas where there has been a history of ice forming along the eaves causing a backup of water as designated in Table R301.2(1), an ice barrier shall be installed for asphalt shingles, metal roof shingles, mineral-surfaced roll roofing, slate and slate-type shingles, wood shingles and wood shakes. The ice barrier shall consist of not fewer than two layers of underlayment cemented together, or a self-adhering polymer-modified bitumen sheet ... and extend from the edges of all roof surfaces to a point not less than 24 inches (610 mm) inside all exterior wall lines of the building. On roofs with slope equal to or greater than 8 units vertical in 12 units horizontal, the ice barrier shall also be applied not less than 36 inches (914 mm) measured along the roof slope from the eave edge." Detached accessory structures without conditioned floor area are excepted. The same amendment fills in Table R301.2(1) with "ICE BARRIER UNDERLAYMENT REQUIRED: Yes." The Building Inspection Office's own "Detail Sheet - Roof" standard details handout independently illustrates the same 24-inch minimum from the exterior wall edge.
Sheridan County Public Works Department - Building Division (Sheridan County, Wyoming (unincorporated area, geographically limited -- see description))
Sourced to the County's own filled-in copy of IRC Table R301.2(1), Climatic and Geographic Design Criteria, on file in the same Public Works document collection as the Building Standards instrument: the "Ice Barrier Underlayment Required" column reads "YES, Pitches less than 4:12 & Mountainous Areas." The same table gives Ground Snow Load 30 psf, Wind Speed 115 mph and Seismic Design Category B for the county. The document itself is captioned to a 2015 International Building Code printed page (page 97) rather than restamped to the County's current 2021 edition, though it was filed in the same document batch as the 2023 Building Standards revision; this record reports the filled-in values as published and does not assume the County has since revised them.
Teton County, Wyoming - Planning & Building Department (Teton County, Wyoming)
County Building Codes Resolution Section 7 amends IRC Table R301.2, Climatic and Geographic Design Criteria, to state "Ice Barrier Underlayment Required: YES" for Teton County, alongside Weathering "D1, D2" and a 34-inch frost line depth. The County's separate Design Criteria reference page republishes the identical figure. Neither document gives a numeric extension distance; the base 2024 IRC's own ice-barrier extension provision, triggered by this designation, was not independently read this session.
Town of Jackson - Planning & Building Department (Town of Jackson, Wyoming)
Town Code Section 15.17.010.B, item 7, amends IRC Table R301.2(1), Climatic and Geographic Design Criteria, to state "Ice shield underlayment required: Yes" for the Town of Jackson. The same amended table lists WEATHERING: Severe and FROST LINE DEPTH: 34 inches.
Ice barrier not required (explicit) — Colorado (36)
Adams County - Building Safety Division (Adams County, Colorado (unincorporated))
"Installation of ice and water shield is not required in Adams County. If installed, it must meet the installation requirements set forth in the 2024 International Residential Code and the manufacturer's installation instructions."
Arapahoe County - Building Division (Arapahoe County, Colorado (unincorporated))
The county's own adopted climate-design-criteria table (Table R301.2(A), part of the 2021 IRC amendments in Resolution 21-394) lists "Ice Barrier Underlayment required: NO" for unincorporated Arapahoe County. Neither this table nor the county's 2024 Residential Re-roofing Guide amend or otherwise require an ice barrier.
Building Department - City of Florence (City of Florence, Colorado)
Florence Municipal Code Sec. 15.08.020, item S, amends Section R301.2 by the addition of its own design-criteria table; the printed cell reads "Ice Barrier Underlayment Required No."
City and County of Broomfield - Building Division (City and County of Broomfield, Colorado)
There has not been a substantial history of ice damming; therefore, no special treatment of eaves is required. Ice and water shields are not required by the code. Adequate ventilation and correct insulation can prevent ice damming from occurring.
City and County of Denver - Community Planning and Development (City and County of Denver, Colorado)
Table R301.2 Climatic and Geographic Design Criteria in Denver's Roofing Guide and Checklist lists "Ice Barrier Underlayment Required: No"; the guide states "Self-adhering bitumen installed at the eaves and rakes to two feet inside the exterior wall is NOT required."
City of Boulder - Building Permits & Inspections (City of Boulder, Colorado)
Table R301.2(1) climatic and geographic design criteria for the City of Boulder Residential Building Code states: "Ice barrier underlayment required = NO."
City of Brighton - Building Division (City of Brighton, Colorado)
Ice shield is not required (unless required by manufacturer).
City of Cañon City - Building Department (City of Cañon City, Colorado)
Cañon City Municipal Code Sec. 15.04.030 (Amendments), item I, amends Table R301.2(1) of the adopted IRC; the printed cell for "Ice Barrier Underlayment Required" reads "Not Required."
City of Castle Pines Building Department (City of Castle Pines, Colorado)
Ice Barrier is not required (item 6 of Residential Roofing Requirements).
City of Delta Building Department (City of Delta, Colorado)
An earned negative read from the instrument itself, not inferred from silence: the city's completed IRC Table R301.2(1) at Ch. 15.04.030(B) (Ord. 7, Sec. 1, 2021) states "Ice Barrier Underlayment Required: NO," and 2018 IRC R905.2.7.1 applies the ice-barrier requirement only where that table entry requires it. No other amendment in Ch. 15.04.030 touches R905.
City of Federal Heights Building Department (City of Federal Heights, Colorado)
Ice and water shield is not required unless specified per the manufacturer's installation instructions. This is the city's own adopted determination rather than an Adams County one: Ordinance No. 23-02, which adopts Federal Heights's technical codes, states that "Table R301.2 is repealed and reenacted to provide" a replacement table whose "Ice Shield Underlayment Requirement" reads "No" (alongside Ground Snow Load 40 lbs. per square foot, Seismic Design Category B, Weathering Severe, Frost Line Depth 36 Inches, Air Freezing Index 712, Mean Annual Temp 50.3F). Neighbouring Adams County jurisdictions reach the opposite conclusion, so this answer does not travel across the city boundary.
City of Fountain (permits via Pikes Peak Regional Building Department) (City of Fountain, Colorado)
The PPRBD regional code requires an ice barrier only for "properties that are above 7,000 ft. elevation"; Fountain sits at roughly 5,500 ft, below the trigger, so the requirement does not apply to properties in the city. (See 2023 PPRBC section RBC303.4.2 Table R301.2 footnote D and 2021 IRC section 905.1.2) Per PPRBD regional guidelines, which govern permits for Fountain. Fountain's own elevation (~5,538 ft) is well below the 7,000 ft trigger, so this rarely applies to Fountain addresses in practice.
City of Greeley - Building Inspection Division (City of Greeley, Colorado)
"Ice Barrier Underlayment Required: NO" (IRC Table R301.2(1) as added by § 22-87). Footnote (8) states the criterion: "In accordance with sections R905.1.2, R905.4.3.1, R905.5.3.1, R905.6.3.1, R905.7.3.1 and R905.8.3.1, where there has been a history of local damage from the effects of ice damming, the jurisdiction shall fill in this part of the table with 'yes.' Otherwise, the jurisdiction shall fill in this part of the table with 'no.'"
City of Lakewood - Building Division (City of Lakewood, Colorado)
An ice barrier underlayment is not required. This rests on Lakewood's own adopted table, not on a Jefferson County document: Lakewood Municipal Code 14.09.040 replaces Table R301.2 in its entirety, and the replacement table's "Ice Barrier required" column is filled in "NO" (alongside Ground Snow load 30 PSF, Seismic Design category B, Weathering Severe, Frost depth 36 inches, Air Freezing index 532, Mean Annual temp 51 F). No amendment to R905.1.2 appears anywhere in the city's Chapter 9 amendments, so nothing reinstates the requirement the table declines. Lakewood self-administers its own building permits, and neighbouring Jefferson County jurisdictions reach the opposite conclusion, so a roofer crossing a Lakewood boundary should not carry this answer with them. The city's residential roof/re-roof handout adds that Ice & Water Shield (or a similar self-adhering bitumen product) may be used in lieu of a double layer of felt underlayment for the entire roof when the slope is less than 4:12.
City of Lone Tree - Building Division (City of Lone Tree, Colorado)
Ice and water is not required (per General Requirements section).
City of Northglenn - Building Division (City of Northglenn, Colorado)

City of Yuma - Building Inspection (City of Yuma, Colorado)
IRC Table R301.2(1) as amended by item (G) of Yuma Municipal Code § 15.10.030 lists "Ice Shield Underlayment Required No".
Delta County Planning and Community Development (Delta County, Colorado)
Outside the Highway 92 and Highway 50 Overlay Districts, Delta County has not adopted building codes for the unincorporated area, so the county imposes no ice-and-water-shield membrane requirement there. Within the two overlay districts, development is subject to the 2003 International Building Code (Resolution 2006-R-016 for Highway 92; Ordinance 2009-01 and Resolution 2009-R-055 for Highway 50); this record does not characterize the 2003 IBC's own ice-barrier provisions.
Mesa County Building Department (Mesa County, Colorado)
The Building Department's Reroof Policy (effective September 2025) states ice barrier membrane is not required along the eaves in areas of the county designated at a 30-psf ground snow load, which covers Grand Junction and the surrounding area, DeBeque, Little Park, the Glade Park Store area, and Gateway per the county's own snow and wind load table. The policy does not state a separate eave ice-barrier requirement for the county's higher-snow-load zones (40 to 100 psf, e.g. Mesa, Powderhorn, Collbran, the Vega Area, and Mesa Lakes); roofers working in those higher-elevation areas should confirm directly with the Building Department.
Saguache County Land Use Office (Saguache County, Colorado)
Saguache County has not adopted a building code. The county's Land Use FAQ states plainly that the county "does not have building codes," and the 2025 Land Development Code (effective November 18, 2025, read in full, all 271 pages) contains no IRC/IBC adoption and no provision requiring an ice-and-water-shield membrane anywhere in the document. No county-enforced ice barrier requirement applies.
Town of Akron - Building Department (Town of Akron, Colorado)
The Town of Akron's Building Department page states: "Ice and water guard: NOT required by the Town of Akron; please check with your insurance company, as this may be a requirement."
Town of Elizabeth Building Department (Town of Elizabeth, Colorado)
Table R301.2(1) as completed by § 18-2-40(j) prints "Ice barrier Underlayment Required" as "NO".

Town of Foxfield Building Permits (SAFEbuilt Inc.) (Town of Foxfield, Colorado)
Table R301.2(1) as filled in by § 18-2-30, item (10), prints "Ice Shield Underlayment Required" as "NO." This corroborates the Town's separately cited SAFEbuilt Residential Reroofing Requirements handout, which independently states "ice-and-water shield is not required."
Town of Kersey Building Inspection Department (Town of Kersey, Colorado)
Kersey Municipal Code § 18-45(13) fills in IRC Table R301.2(1) and prints, in its single data row, "Ice Barrier Underlayment Required: No" (the full row reads "30psf 115 No B Severe 30 in. Slight to Moderate 1 No * 1000 45°F"). That is the Town's own adopted, codified instrument and it governs. A "2024 IRC Residential Re-roofing" guide linked from the Town's Building Permit page states the opposite - "ICE AND WATER SHIELD IS REQUIRED ON ALL ROOFS" - but that document is not a Kersey instrument: it is a SAFEbuilt handout distributed unchanged to multiple client towns (the file Kersey links is byte-for-byte identical to the copies published by Dacono and Windsor, and its own text carves out "THE TOWN OF TIMNATH" by name). A shared handout cannot establish a Kersey-specific climatic value, so the codified table's "No" is what this record reports.
Town of Kiowa - Building Department (Town of Kiowa, Colorado)
The Town's Building Department page states, under Section 18-2-40, IRC Table R301.2 requirements: "ice barrier underlayment is not required."
Town of Larkspur - Building Department (Town of Larkspur, Colorado)
Larkspur Municipal Code § 18-6-40(13)'s Table R301.2(1) amendment prints "No" in the "Ice Barrier Underlayment Required" column.

Town of Parker - Building Division (Town of Parker, Colorado)
Town of Parker Building Division Re-Roofing Requirements handout states "Ice and Water Required- No, not applicable." for asphalt shingle re-roofs (all other roof materials must meet code or manufacturer specs).
Town of Saguache Building Site Permits (Town of Saguache, Colorado)
The Town of Saguache's codified Municipal Code — all twelve substantive chapters, read in full, current through Ordinance No. 2023-2 — contains no adopted IBC/IRC edition and no chapter addresses an ice-and-water-shield membrane requirement, so none is enforced by the Town.
Town of Stratton - Building Permits (Town of Stratton, Colorado)
The Town's only adopted construction code is the 2025 Colorado Wildfire Resiliency Code, adopted by reference via Ordinance No. 94B (no IRC/IBC has been adopted). The CWRC, read in full, contains no ice-barrier or ice-and-water-shield provision anywhere in its text.
Town of Westcliffe - Building Department (Town of Westcliffe, Colorado)
Westcliffe Municipal Code § 3-2-2(B)(3)'s Table R301.2(1) insert prints "Ice Barrier Underlayment NO" as the town's filled-in value for this row.
Weld County - Building Inspection Division (Weld County, Colorado (unincorporated))
Weld County's amended IRC Table R301.2(1) (Climatic and Geographic Design Criteria, Sec. 29-2-30.B, amending Table 301.2) lists "ICE SHIELD UNDER-LAYMENT = NO" as the countywide determination.

Ice barrier not required (explicit) — Florida (133)
Alachua County - Building Division (Alachua County, Florida (unincorporated))

Florida Building Code, Residential, 8th Edition (2023): "R905.1.2 Ice barriers. Reserved." There is no ice-barrier requirement in the Florida code, and Bay County's building chapter (County Code Chapter 6), which adopts the Florida Building Code in toto, does not amend the roofing provisions.

Lee County - Community Development, Building and Permitting Services (Lee County, Florida (unincorporated))
Florida Building Code, Residential, 8th Edition (2023): "R905.1.2 Ice barriers. Reserved." There is no ice-barrier requirement in the Florida code, and Lee County's building chapter (Land Development Code Chapter 6) does not amend the roofing provisions. Self-adhered underlayment is still used in Florida, but as underlayment or a secondary water barrier, not as an ice barrier.
Leon County - Building Plans Review and Inspection Division (Leon County, Florida (unincorporated))

Martin County - Building Department (Martin County, Florida (unincorporated))
Florida Building Code, Residential, 8th Edition (2023), Section R905.1.2 reads in full: "Ice barriers. Reserved." Martin County's building regulations (Code Chapter 21) add no ice barrier requirement. A self-adhered underlayment is still an accepted choice: the county's Reroof Windstorm Loss Mitigation Certification lists, as the first of three secondary water barrier methods, "a self-adhering polymer modified Bitumen underlayment complying with ASTM D1970 applied over the entire roof deck."
Miami-Dade County - Regulatory and Economic Resources, Building (Miami-Dade County, Florida (unincorporated))

Self-adhered underlayment is still used in Florida, but as a secondary water barrier or underlayment method, not as an ice barrier.
Osceola County - Community Development Department, Building Office (Osceola County, Florida (unincorporated))
Florida Building Code, Residential, 8th Edition (2023): "R905.1.2 Ice barriers. Reserved." The Florida code has no ice-barrier requirement, and Osceola County's building chapter (County Code Secs. 5-56 to 5-62) contains no roofing provision; the state registry lists no county amendment. Self-adhered underlayment is still used in Florida, but as an underlayment or secondary water barrier method, not as an ice barrier. The county's codified chapter still names the 1994 Standard Building Code (Sec. 5-56); this note states the 2023 Florida Building Code, which state law applies statewide without local adoption and which the county's Building Office says it enforces; the 1994 text was not obtained.
Palm Beach County Planning, Zoning and Building Department - Building Division (Palm Beach County, Florida (unincorporated))
Florida Building Code, Residential, 8th Edition (2023), Section R905.1.2 reads in full: "Ice barriers. Reserved." Palm Beach County's amendments to the 8th Edition (Ord. No. 2024-012) do not add an ice barrier requirement. A self-adhered underlayment is still an accepted choice: the County's reroofing form for asphalt shingles lists "Self-Adhered (Direct to Deck)" ASTM D1970 polymer-modified bitumen underlayment as one of three underlayment options, alongside a taped-seam method and two layers of felt.

Polk County - Building Division (Polk County, Florida (unincorporated))
Not required anywhere in Florida. Florida Building Code, Residential, 8th Edition (2023) reads "R905.1.2 Ice barriers. Reserved." Polk County's Construction Code (Polk County Code Chapter 5, Article II) makes no technical amendment, and the Florida Building Commission's registry of local amendments lists none for Polk County. A full-deck ASTM D1970 self-adhering underlayment remains one of the code's permitted underlayment methods for shingle roofs (Section R905.1.1.1).
Putnam County - Building Department (Putnam County, Florida (unincorporated))
Not required. The Florida Building Code, Residential, 8th Edition (2023) reads "R905.1.2 Ice barriers. Reserved." and, for asphalt shingles, "R905.2.7 Ice barrier. Reserved."

Seminole County - Building Division (Seminole County, Florida (unincorporated))
Florida Building Code, Residential, 8th Edition (2023): "R905.1.2 Ice barriers. Reserved." There is no ice-barrier requirement in the Florida code, and Seminole County's amendments (Chapter 40 and its Appendix A) do not touch the roofing chapter. Self-adhered underlayment is still used in Florida, but as a secondary water barrier or underlayment method, not as an ice barrier.
St. Johns County - Building Department (St. Johns County, Florida (unincorporated))
Not required. The Florida Building Code, Residential, 8th Edition (2023) reads "R905.1.2 Ice barriers. Reserved." and, for asphalt shingles, "R905.2.7 Ice barrier. Reserved." Neither St. Johns County Ordinance No. 2022-33 (read in full; its technical amendments cover address identification and flood provisions only) nor any registered County amendment adds an ice barrier. A self-adhering ASTM D1970 underlayment remains one of the permitted underlayment methods; it is not prohibited. The County states that it enforces the 2023 8th Edition; its administrative ordinance adopts the 2020 edition of the code's administrative chapter only.
Sumter County - Building Services (Sumter County, Florida (unincorporated))
Not required anywhere in Florida. The Florida Building Code, Residential, 8th Edition (2023), reads "R905.1.2 Ice barriers. Reserved." Sumter County Code Chapter 6, read in full, does not address ice barriers. A self-adhered underlayment may still be used as one of the state code's underlayment options.
Suwannee County - Building Department (Suwannee County, Florida (unincorporated))
Not required. The Florida Building Code, Residential, 8th Edition (2023) reads "R905.1.2 Ice barriers. Reserved." and, for asphalt shingles, "R905.2.7 Ice barrier. Reserved." The County's building chapter (County Code Chapter 18, read in full), which still names the 2010 code, adds no ice barrier; the Building Department states that it enforces the 8th Edition. The County's own Reroof Requirements list a fully adhered ASTM D1970 self-adhering underlayment as one permitted underlayment method; it is an option, not an ice barrier requirement.
Town of Cutler Bay - Building Division (Town of Cutler Bay, Florida)
Cutler Bay is in the High-Velocity Hurricane Zone, where roofing follows Florida Building Code, Building, Sections 1512 through 1525; those sections contain no ice barrier requirement, and the Residential volume's ice barrier section reads "R905.1.2 Ice barriers. Reserved." Miami-Dade County Code Chapter 8 (read in full) adds none, and the Town has no building code chapter of its own. A self-adhered underlayment used as the underlayment the product approval and Section 1518 call for is not prohibited.
Town of Davie - Building Division (Town of Davie, Florida)
The High-Velocity Hurricane Zone roofing sections that apply in Davie (Florida Building Code, Building, Sections 1512 through 1525) contain no ice-barrier requirement, and the Residential volume reserves its ice-barrier section ("R905.1.2 Ice barriers. Reserved."). Neither Broward County's countywide amendments to the Florida Building Code (Chapter 1, Administration) nor the Town's building chapter (Town Code Chapter 5) adds one. Self-adhered ("peel and stick") underlayment is still widely used as the underlayment or secondary water barrier, and the Town's Roofing Checklist schedules a separate Peel & Stick inspection where it is installed. This record states the 2023 Florida Building Code provisions, the edition the Building Division's roofing forms cite; the Town's codified adoption (Town Code Section 5-1) names the Florida Building Code 2004 Edition together with "any and all additional revisions made subsequent to that date".

Miami Lakes is in the High-Velocity Hurricane Zone, where roofing follows Florida Building Code, Building, Sections 1512 through 1525; those sections contain no ice barrier requirement, and the Residential volume's ice barrier section reads "R905.1.2 Ice barriers. Reserved." Neither Miami-Dade County Code Chapter 8 (Article I, read in full, including its local technical amendments in section 8-31) nor Town Code Chapter 4 (read in full) adds one. A self-adhered underlayment used as the underlayment the product approval and Section 1518 call for is not prohibited.

A self-adhering ASTM D1970 underlayment remains one of the permitted underlayment methods under section R905.1.1.1, and it is one of the five underlayment options the Village's roof inspection policy lists; it is not prohibited.
Village of Palmetto Bay - Building & Permitting Department (Village of Palmetto Bay, Florida)

Reserved." Neither Miami-Dade County Code Chapter 8 (read in full) nor the Village's Florida Building Code amendments (Code of Ordinances Appendix B, read in full) add one. A self-adhered underlayment used as the underlayment the product approval and Section 1518 call for is not prohibited.

Florida Building Code, Residential, 8th Edition (2023): "R905.1.2 Ice barriers. Reserved." There is no ice-barrier requirement in the Florida code, and Volusia County's amendments (Volusia County Code Chapter 22, Article I, including the technical amendments in Sec. 22-4) do not touch the roofing chapter.

Ice barrier not required (explicit) — Georgia (6)
City of Newnan, Georgia - Building Department (City of Newnan, Georgia)
NEWNAN ANSWERS THIS ITSELF, WHICH ALMOST NO GEORGIA JURISDICTION DOES. The Residential Code leaves its climatic and geographic criteria table for the local jurisdiction to complete, and the Newnan Building Department publishes a completed one: a Design Criteria sheet headed "TABLE R301.2(1) CLIMATIC AND GEOGRAPHIC DESIGN CRITERIA". Under the column headed "Ice Barrier Underlayment Required" the City's entry is "NO". So no ice barrier underlayment is required by the City's own determination. The rest of the same row, so a roofer can see the context it sits in, gives a ground snow load of 5 PSF, a wind design speed of 115 mph with topographic effects and special wind region both "N/A" and windborne debris zone "NO", seismic design category B, weathering "MODERATE", a frost line depth of 5 inches, termite exposure "VERY HEAVY", a winter design temperature of 22, flood hazards "2/6/2013", an air freezing index of 67 and a mean annual temperature of 62.2. TWO CAUTIONS. This is the City's determination for code purposes and it is not a waterproofing recommendation: a shingle manufacturer's warranty, a low-slope detail or a valley or eave condition can still call for a self-adhering membrane, and nothing here relieves you of the manufacturer's instructions the Code makes binding. And the sheet is an undated Building Department publication whose flood-hazard entry points at a 2013 map date, so confirm the entry has not been revised when the permit is pulled.
City of Sandy Springs, Georgia - Community Development Department, Building Division (City of Sandy Springs, Georgia)
Sandy Springs answers this one itself. The International Residential Code leaves the ice barrier to the local jurisdiction to fill in on Table R301.2(1), and the City has filled it in: its Single Family Residential Building Permit Checklist publishes a table headed "Sandy Springs' Table R301.2(1) Climatic and Geographic Design Data" whose "Ice Barrier Underlayment Required" column reads "No". The same row gives a ground snow load of 5 psf, a winter design temperature of 22 degrees F, a frost line depth of 12 inches, moderate weathering, a very heavy termite exposure, an air freezing index of 102 and a mean annual temperature of 59.4 degrees F. Two limits on that. The checklist is a submittal document for major alterations, building additions, new buildings and decks more than six feet above grade, so it is the City's design data for plan-reviewed work rather than a rule written for a re-roof. And it is an old form: it recites the 2006 International Residential Code with Georgia State Amendments and is marked "Revised 2007", while Georgia's mandatory residential code is now the 2024 edition. Neither the City's building chapter nor the Georgia amendment packet adds an ice barrier requirement, so nothing contradicts the City's "No", but confirm it with the Community Development Department before leaving an ice barrier out of a specification.
City of Stonecrest, Georgia - Building and Permitting Division (City of Stonecrest, Georgia)
STONECREST ANSWERS THIS ITSELF, WHICH ALMOST NO GEORGIA JURISDICTION DOES. The Residential Code leaves its climatic and geographic criteria table for the local jurisdiction to complete, and Code section 7-24(b)(1)a provides that "Table 301.2(1) in chapter 3 shall be completed by adding the following information to the blank spaces", then gives twelve entries. Entry 11 reads, in full: "Ice Barrier Underlayment Required — No." So no ice barrier underlayment is required by the City determination. The other entries in the same list are a ground snow load of 8 pounds per square foot, wind speed (fastest mile) 90, seismic design category B, moderate weathering, a 12-inch minimum frost line depth, very heavy termite damage, moderate to severe decay damage, a winter design temperature of 22 degrees Fahrenheit, flood hazard yes, an air freezing index of 225, and a mean annual temperature of 55 to 60 degrees Fahrenheit. Two cautions. This is the City statutory determination and not a waterproofing recommendation: a shingle manufacturer warranty, a low-slope detail or a valley or eave condition can still call for a self-adhering membrane, and nothing here relieves you of the manufacturer instructions the Code makes binding. And the entry is part of an ordinance codified through November 2024, so confirm it has not been amended when you pull the permit.
Fayette County, Georgia - Department of Building Safety (Fayette County, Georgia)
Fayette County has answered this one for itself, which most Georgia jurisdictions have not. The Residential Code leaves its table of climatic and geographic design criteria to be filled in by the adopting jurisdiction, and the County's Department of Building Safety publishes a completed table headed "Climatic and Geographic Design Criteria - Fayette County Georgia". Its row for ice barrier underlayment gives the answer "No". That entry is what switches the Code's ice-barrier provision on or off, so no ice barrier or ice-and-water-shield membrane is required by code on a Fayette County roof. The Georgia State Amendments to the 2024 International Residential Code make no change to the Code's roofing chapter and so do not disturb it. Two practical caveats that are not code requirements: a shingle manufacturer's own instructions may still call for an eave membrane as a condition of its warranty, and the County's table says nothing about what a particular roof needs at a valley, a low slope or a north-facing eave. Confirm the current table with the Department of Building Safety on 770-305-5403 before relying on it for a design.
Macon-Bibb County, Georgia - Department of Building and Fire Safety (Macon-Bibb County, Georgia)
Not required at the roof edge, and this is a local determination rather than a state one - Macon-Bibb County filled in its own row of the code's climatic and geographic criteria table. Its Residential Roofing page states: "Per 2018 IRC Table R301.2(1), as modified for the conditions encountered within Macon-Bibb County. Ice and Water Shield is not required at the roof edge to protect the roof from the effects of ice damming. Based on our climatic conditions, Macon-Bibb County does not experience extreme freezing and thawing cycles experienced in the Northern climate zones." Note this answers the ice barrier at the eave only, and the County answers the valley question separately and in the roofer's favour. The Code recognises three prescriptive valley-lining methods - metal lining at least 24 inches wide in one of the corrosion-resistant metals the Code tabulates, two plies of mineral surfaced roll roofing complying with ASTM D 3909 or ASTM D 6380 Class M, or, for a closed valley, one ply of smooth roll roofing complying with ASTM D 6380 and at least 36 inches wide, with self-adhering polymer bitumen underlayment complying with ASTM D1970 permitted in lieu of the lining material. Macon-Bibb County says it "recognizes all three of the available options" for flashing closed valleys and "does not mandate which option the contractor is prescriptively required to follow." So ice-and-water shield in the valley is one permitted method here, not the only one.
Paulding County, Georgia - Community Development Department, Building & Permitting Division (Paulding County, Georgia)
Paulding County has answered this one for itself, which most Georgia jurisdictions have not. The Residential Code leaves its Table 301.2(1) of climatic and geographic criteria to be filled in by the adopting jurisdiction, and Paulding County Code section 18-31(d)(3) does exactly that, revising the table "by adding the following information to the blank spaces" and giving, as item h, "Ice Barrier Underlayment Required - No." That entry is what switches the Code's ice-barrier provision on or off, so no ice barrier or ice-and-water-shield membrane is required by code on a Paulding County roof. The Georgia State Amendments to the 2024 International Residential Code make no change to the Code's roofing chapter and so do not disturb it. Two practical caveats that are not code requirements: a shingle manufacturer's own instructions may still call for an eave membrane as a condition of its warranty, and the County's answer says nothing about what a particular roof needs at a valley, a low slope or a north-facing eave. The table entry was last amended by Ordinance No. 24-01, adopted January 23, 2024.
Ice barrier not required (explicit) — Idaho (11)
Ada County Development Services - Building Division (Ada County, Idaho)
Sourced from Ada County's own climatic and geographic design criteria, not inferred from climate. The County's amendment to the 2018 IRC (Ada County Code 7-2-5) states that "Table R301.2(1) Climatic and Geographic Design Criteria" shall be deleted "in its entirety and replace[d] with the following Table R301.2(1)," and the replacement table the County publishes carries "No" in the column headed "Ice Barrier Underlayment Required." Idaho's state rule does not answer this question either way: IDAPA 24.39.30 amends nothing in Chapter 9 of the 2018 IRC, and Table R301.2(1) is the one part of Part III of the residential code that Idaho Code leaves a county free to amend for local conditions. Nothing in the County's entry stops a shingle manufacturer's printed installation instructions, or a particular roof's exposure and history of ice damming, from calling for eave protection anyway.
Canyon County Development Services Department - Building Division (Canyon County, Idaho)
Sourced from Canyon County's own climatic and geographic design criteria, not inferred from climate. The County has replaced the model table for itself: it publishes that Section R301.2, "Climatic And Geographic Design Criteria", table R301.2(1) "shall be changed to read as follows", and the table it prints in place of the model one carries "No" in its "Ice Shield Underlaying Required" column. Idaho's state rule does not answer this question either way: IDAPA 24.39.30.600.03 amends nothing in Chapter 9 of the 2018 International Residential Code, and Table R301.2(1) is the one part of Part III that Idaho Code 39-4116(4)(c) leaves a county free to fill in and amend for local conditions. Nothing in the County's entry stops a shingle manufacturer's printed installation instructions, or a particular roof's exposure and history of ice damming, from calling for eave protection anyway.
City of Boise - Planning and Development Services, Building Division (City of Boise, Idaho)
Sourced from Boise's own climatic and geographic design criteria, not inferred from climate. The City of Boise publishes its filled-in 2018 IRC Table R301.2(1) on its current-codes page, and the entry reads "ICE BARRIER UNDER LAYMENT REQUIRED h : NO", against the table's own footnote "In accordance with Sections R905.2.7, R905.4.3.1, R905.5.3.1, R905.6.3.1, R905.7.3.1 and R905.8.3.1, where there has been a history of local damage from the effects of ice damming." The rest of that table is worth having in front of you on a Boise roof: ground snow load 20 psf, with a design roof load of not less than a uniform snow load of 25 psf; weathering severe; frost line depth 24 inches; winter design temperature 10 degrees F; air freezing index 894; mean annual temperature 51.1 degrees F. Idaho's state rule does not answer the ice barrier question either way: IDAPA 24.39.30.600.03 amends nothing in Chapter 9 of the 2018 International Residential Code, and Table R301.2(1) is the one part of Part III that Idaho Code 39-4116(4)(c) leaves a city free to fill in and amend for local conditions. Nothing in the City's entry stops a shingle manufacturer's printed instructions, or a particular roof's exposure, from calling for eave protection anyway.
City of Eagle - Building Division (City of Eagle, Idaho)
Sourced from Eagle's own design criteria, not inferred from climate. The City of Eagle publishes a one-page sheet headed "Climatic And Geographic Design Criteria (SECTION R301, IRC 2018)", and its entry reads "ICE BARRIER UNDERLAYMENT REQUIRED: NO". The rest of that sheet is worth having in front of you on an Eagle roof, as the City prints it: ground snow load 20 psf, with a design roof load of not less than a uniform snow load of 25 psf; weathering severe; frost line depth 24 inches; winter design temperature 10 degrees F; termite slight to moderate; decay none to slight; air freezing index 894; mean annual temperature 51.1 degrees F; climate zone 5. Idaho's state rule does not answer the ice barrier question either way: IDAPA 24.39.30.600.03 amends nothing in Chapter 9 of the 2018 International Residential Code, and Table R301.2(1) is the one part of Part III that Idaho Code 39-4116(4)(c) leaves a city free to fill in and amend for local conditions. Nothing in the City's entry stops a shingle manufacturer's printed installation instructions, or a particular roof's exposure, from calling for eave protection anyway.
City of Jerome - Building Safety Department (City of Jerome, Idaho)
City of Lewiston - Community Development Department, Building Services (City of Lewiston, Idaho)
Sourced from Lewiston's own adopted design criteria, not inferred from climate. Lewiston City Code Sec. 10-9(7) amends Table R301.2(1) of the International Residential Code and directs that "Ice Shield Underlayment Required" be annotated with "No." The rest of that amendment is worth having in front of you on a Lewiston roof: "Ground Snow Load is 30 psf" annotated with "Roof Snow Load is 25 psf"; Wind Speed 115; Seismic Design Category B; Weathering Severe; Frost line depth 24 inches; Termite S to M; Decay None to Slight; Winter Design Temp 6 degrees Fahrenheit; Air Freezing Index 800; Mean Annual Temp 53 degrees Fahrenheit; and, for flood hazards, "Floodplain Ordinance 4579 effective 09-10-2012, and FIRM maps as currently adopted." Idaho's state rule does not answer the ice barrier question either way: IDAPA 24.39.30.600.03 amends nothing in Chapter 9 of the 2018 International Residential Code, and Table R301.2(1) is the one part of Part III that Idaho Code 39-4116(4)(c) leaves a city free to fill in and amend for local conditions -- which is exactly what Lewiston has done. Nothing in the City's entry stops a shingle manufacturer's printed instructions, or a particular roof's exposure, from calling for eave protection anyway.
City of Meridian - Community Development Department, Building Services (City of Meridian, Idaho)
Sourced from Meridian's own adopted climatic and geographic design criteria, not inferred from climate. Meridian City Code 10-1-3(K) completes Table R301.2(1) of the adopted residential code and prints, in that table, "ICE BARRIER UNDER LAYMENT REQUIRED: No". The same table sets "WEATHERING: Severe", "FROST LINE DEPTH: 24 inches" and "WINTER DESIGN TEMP: 10 degrees F (annual mean temperature: 51.1 degrees F)", so the absence of an ice barrier requirement here is a deliberate entry by the City rather than a mild-climate default. Idaho's state rule does not answer this question: IDAPA 24.39.30.600.03 amends nothing in Chapter 9 of the 2018 International Residential Code, and Table R301.2(1) is the one part of Part III that Idaho Code 39-4116(4)(c) leaves a city or county free to fill in and amend for local conditions. Two practical notes. An ice barrier is not forbidden, and Meridian roofers install one by choice: a residential re-roof permit issued by the City in November 2025 describes the work as "Provide and install ice and water shield, synthetic underlayment, starter strip, OC Duration shingles". Neighbouring jurisdictions complete the same table for themselves and may answer differently, so confirm the answer for the address, not for the metro.
City of Nampa - Building Safety & Code Division (City of Nampa, Idaho)
Sourced from Nampa's own climatic and geographic design criteria, not inferred from climate, and the City states it twice. Nampa City Code 4-2-2 amends Table R301.2(1) of the adopted residential code and answers its "ICE BARRIER UNDERLAYMENT REQUIRED" row NO, cross-referencing the base code sections R905.2.7.1, R905.4.3.1, R905.5.3.1, R905.6.3.1, R905.7.3.1 and R905.8.3.1 "where there has been a history of local damage from the effects of ice damming." The Climate and Geographic Design Criteria sheet the City's Building Safety and Code division publishes today, dated 3/12/2024, prints the same answer: "ICE BARRIER UNDERLAYMENT REQUIRED: No". The same two documents set weathering as Severe and print "WINTER DESIGN TEMP: 10 degrees F", so the absence of an ice barrier requirement here is a deliberate entry by the City rather than a mild-climate default. Idaho's state rule does not answer this question: IDAPA 24.39.30.600.03 amends nothing in Chapter 9 of the 2018 International Residential Code, and Table R301.2(1) is the one part of Part III that Idaho Code 39-4116(4)(c) leaves a city or county free to fill in and amend for local conditions. An ice barrier is not forbidden, and a roofer may install one by choice or because a manufacturer's warranty asks for it. Neighbouring jurisdictions complete the same table for themselves and may answer differently, so confirm the answer for the address, not for the metro.
City of Star - Building Department (City of Star, Idaho)
STAR ANSWERS THIS QUESTION ITSELF, AND THE ANSWER IS NO. The last line of the City's Adopted Codes & Design Criteria form, Form #313 revision 04-2024, reads "Ice Barrier Underlayment Required? - No". The residential code leaves the ice barrier question to the jurisdiction's own entry in its climatic and geographic design criteria, and Star's entry is a negative, so no ice barrier underlayment is mandated by code for a roof inside the city limits. THREE THINGS THAT DOES NOT MEAN. It does not stop a manufacturer from requiring an ice barrier as a condition of its own warranty, and the code makes the manufacturer's printed installation instructions binding, so read them before leaving one out. It does not travel across the city line; a neighbouring Idaho jurisdiction may answer the same question Yes, and several do. And it is a code answer rather than a building-science one, so a north-facing low slope over an unvented or poorly insulated space can still ice-dam in Star. This value rests on the City's published design criteria form rather than on an ordinance; if a job turns on it, confirm the current answer with the Building Department before ordering material.
City of Twin Falls - Building Safety Department (City of Twin Falls, Idaho)
Sourced from the City of Twin Falls' own published design criteria, not inferred from climate. The Building Safety Department's residential design criteria for one- and two-family dwellings and townhouses print "Water and Ice Shield: NO (Must follow roof manufacture's installation requirements for underlayment)". So the City requires no ice barrier underlayment, and the underlayment actually used must go down to the roofing manufacturer's printed instructions, which the code makes binding. The same sheet gives the local conditions behind that call: ground snow load 15 psf, frost depth 24 inches, climate zone 5B, winter heating design temperature 2 degrees, and "Subject to damage from weathering: Severe". Idaho's state rule does not answer this question -- IDAPA 24.39.30.600.03 amends nothing in Chapter 9 of the 2018 International Residential Code, and Table R301.2(1) is the one part of Part III that Idaho Code 39-4116(4)(c) leaves a city or county free to fill in and amend for local conditions.
Minidoka County - Building Department (Minidoka County, Idaho)
THE COUNTY ANSWERS THIS ITSELF, AND THE ANSWER IS NO. The Minidoka County Building Department's Roof & Siding Permit Packet prints a design-criteria table with a row for RESIDENTIAL work. Its column headed ICE BARRIER UNDERLAYMENT REQUIRED carries the entry NO. That is the County's own filled-in climatic and geographic design criteria, published in the packet a roofer files a reroof under, so it is a direct answer rather than an inference from climate. READ IT WITH THE REST OF THE ROW, WHICH IS SET OUT UNDER WIND DESIGN CRITERIA, AND DO NOT OVER-READ IT. It means the County does not require an ice barrier underlayment by code. It does not mean ice damming never happens on a Minidoka County roof, and it does not override a shingle manufacturer's printed instructions, which the code makes binding and which may call for an eave protection membrane as a condition of the warranty. If the manufacturer's instructions require one, install it. WHAT COULD NOT BE CHECKED. The County's own adopting ordinance and any local amendment list are published only through a commercial codifier that refuses automated access, so this rests on the Building Department's own published design criteria rather than on a codified table.
Ice barrier not required (explicit) — Indiana (49)
Bartholomew County, Indiana - Department of Technical Code Enforcement (Bartholomew County, Indiana)
NOT REQUIRED BY THE TABLE IN BARTHOLOMEW COUNTY - BUT THE MANUFACTURER CAN STILL REQUIRE IT, AND THAT IS THE HALF THAT CATCHES PEOPLE OUT. Indiana deletes the model climatic table and substitutes its own county-by-county table: 675 IAC 14-4.4-5 directs "Delete TABLE R301.2(1) and the corresponding footnotes and substitute to read as follows", and the substituted table runs one row per county. Row 3 is Bartholomew, and it carries "No" in the column headed "Ice Shield Underlayment Required". Twenty-seven of Indiana's ninety-two counties carry "Yes" there and they are the northern tier; Bartholomew is not one of them, so an answer carried down from a South Bend, Fort Wayne or Gary job would be wrong here. The rest of the Bartholomew County row reads wind speed 115 mph, seismic design category B, ground snow 20 psf, foundation depth 24 inches, winter design temperature 9 degrees F and weathering Severe. The Indiana State Building Commissioner sets out the qualification in terms: Sections R903.1, R904.1 and R905.1 require roofing materials to be installed in accordance with the manufacturer's installation instructions, so "there are specific counties in which it is always required (per Table R301.2(1)), and specific counties in which it is required only when the roofing manufacturer's written installation instructions require it (per Sections R903 .1, R904.1 and R905 .1)." Bartholomew County is in that second group: the table does not compel an ice barrier, and the shingle manufacturer's printed instructions still can. Neither the County nor the City of Columbus may add a requirement of its own, because IC 22-13-2-3(c) bars a local ordinance more stringent or detailed than the state rules.
Boone County Area Plan Office (Boone County, Indiana)
NOT REQUIRED BY THE COUNTY TABLE HERE, AND THAT IS NOT THE END OF THE QUESTION. Indiana replaces the model climatic table with its own county-by-county Table R301.2(1), and the Boone County row reads Ice Shield Underlayment Required No. The State Building Commissioner's memo explains what that No means: "there are specific counties in which it is always required (per Table R301.2(1)), and specific counties in which it is required only when the roofing manufacturer's written installation instructions require it (per Sections R903.1, R904.1 and R905.1)." Boone is in the second group. So read the printed installation instructions for the shingle actually being installed; if they call for the membrane on that assembly, the code requires it on this job regardless of the table. Boone County publishes no ice-barrier rule of its own and IC 22-13-2-3(c) bars it from writing one.
City of Anderson, Indiana - Permit Center (City of Anderson, Indiana)
NOT REQUIRED BY THE TABLE IN MADISON COUNTY - BUT THE MANUFACTURER CAN STILL REQUIRE IT. Indiana deletes the model climatic table and substitutes its own county-by-county table: 675 IAC 14-4.4-5 directs "Delete TABLE R301.2(1) and the corresponding footnotes and substitute to read as follows", and the substituted table runs one row per county. Row 48 is Madison, and it carries "No" in the column headed "Ice Shield Underlayment Required". Twenty-seven of Indiana's ninety-two counties carry "Yes" there and they are the northern tier; Madison is not one of them, so an answer carried down from a Fort Wayne, South Bend or Gary job would be wrong here. The rest of the Madison County row reads wind speed 115 mph, seismic design category A, ground snow 20 psf, foundation depth 30 inches, winter design temperature 2 degrees F and weathering Severe. The Indiana State Building Commissioner sets out the qualification in terms: Sections R903.1, R904.1 and R905.1 require roofing materials to be installed in accordance with the manufacturer's installation instructions, so "there are specific counties in which it is always required (per Table R301.2(1)), and specific counties in which it is required only when the roofing manufacturer's written installation instructions require it (per Sections R903 .1, R904.1 and R905 .1)." Madison County is in that second group: the table does not compel an ice barrier, and the shingle manufacturer's printed instructions still can. Anderson has no power to add a requirement of its own, because IC 22-13-2-3(c) bars a city, town or county from an ordinance more stringent or detailed than the state rules.
City of Bedford Planning and Zoning Department (City of Bedford, Indiana)
NOT REQUIRED BY THE TABLE IN LAWRENCE COUNTY, BUT THE MANUFACTURER'S INSTRUCTIONS CAN STILL REQUIRE IT. Indiana replaces the model climatic table with its own, one row per county: 675 IAC 14-4.4-5 reads "Delete TABLE R301.2(1) and the corresponding footnotes and substitute to read as follows". Row 47, Lawrence, carries "No" in the column headed Ice Shield Underlayment Required. The State Building Commissioner's guidance of February 25, 2020, which reproduces that table, explains what the No means. Sections R903.1, R904.1 and R905.1 require roofing to be installed in accordance with the manufacturer's installation instructions, so there are counties where the barrier is always required and counties "in which it is required only when the roofing manufacturer's written installation instructions require it". Lawrence County is in the second group. Read the shingle manufacturer's published instructions for the product being installed: if they call for an ice barrier, the code requires it on a Bedford job, and the warranty may depend on it too. Bedford could not add a requirement of its own, because IC 22-13-2-3(c) bars a city from an ordinance more stringent or detailed than the state rules.
City of Carmel, Indiana - Department of Community Services, Building and Code Services (Building Safety Office) (City of Carmel, Indiana)
STATE-GOVERNED, NOT CITY-SET, and county-conditional. Carmel is in Hamilton County, and in Indiana's replacement TABLE R301.2(1) at 675 IAC 14-4.4-5 the Hamilton County row carries "No" in the column headed "Ice Shield Underlayment Required". An ice barrier is therefore not categorically mandated by the table in Carmel, unlike the northern lake-effect counties -- the Allen County row, which governs Fort Wayne, carries "Yes" in the same column. CORRECTED 2026-09-05: this record previously presented the column heading and the cell value glued together with a colon as though that string were printed in the table. It is not; the row and the column are separate, and the reading is given above in the form the table actually takes. An ice barrier can still be required in Carmel by a second, independent route. The Indiana State Building Commissioner's guidance memo "ICE/WATER SHIELD & METAL DRIP EDGE IN CLASS 2 CONSTRUCTION with ASPHALT SHINGLES" (Craig E. Burgess AIA NCARB CPE CBI LEED AP, February 25, 2020) explains that two layers of rule combine: "In short, there are specific counties in which it is always required (per Table R301.2(1)), and specific counties in which it is required only when the roofing manufacturer's written installation instructions require it (per Sections R903.1, R904.1 and R905.1)." Hamilton County falls in the second group, so on a Carmel job the question is decided by the written installation instructions for the particular shingle being installed: read them before bidding, because where they call for an ice barrier the code makes it mandatory. This record no longer asserts what shingle manufacturers generally require in central Indiana, which was stated without a source. Where an ice barrier is triggered, IRC Section R905.1.2 governs its extent, and Indiana does not amend it -- 675 IAC 14-4.4, read in full across its 245 numbered sections, amends four sections of the roofing chapter (R902.4, R905.2.6, R905.2.8 and R905.2.8.4) and R905.1.2 is not among them. The State prints the section as: "In areas where there has been a history of ice forming along the eaves causing a backup of water as designated in Table R301.2(1), an ice barrier shall be installed for asphalt shingles, metal roof shingles, mineral-surfaced roll roofing, slate and slate-type shingles, wood shingles and wood shakes. The ice barrier shall consist of not fewer than two layers of underlayment cemented together, or a self-adhering polymer-modified bitumen sheet shall be used in place of normal underlayment and extend from the lowest edges of all roof surfaces to a point not less than 24 inches (610 mm) inside the exterior wall line of the building. On roofs with slope equal to or greater than eight units vertical in 12 units horizontal (67-percent slope), the ice barrier shall also be applied not less than 36 inches (914 mm) measured along the roof slope from the eave edge of the building. Exception: Detached accessory structures not containing conditioned floor area."
City of Crawfordsville Planning & Building Services (City of Crawfordsville, Indiana)
NOT REQUIRED BY THE TABLE HERE, AND THAT IS NOT THE END OF THE QUESTION. The Indiana Residential Code's Table R301.2(1), as substituted by 675 IAC 14-4.4-5, runs county by county, and the Montgomery County row reads Ice Shield Underlayment Required No. WHAT THE STATE'S OWN MEMO SAYS THE No MEANS. The Indiana State Building Commissioner's memo explains that "there are specific counties in which it is always required (per Table R301.2(1)), and specific counties in which it is required only when the roofing manufacturer's written installation instructions require it (per Sections R903.1, R904.1 and R905.1)." Montgomery is in the second group, so where the shingle manufacturer's instructions call for an ice and water membrane on the assembly being installed, that requirement applies to the job. Read those instructions before deciding the membrane is optional here.
City of Fishers, Indiana - Community Development Department (City of Fishers, Indiana)
NOT AUTOMATICALLY REQUIRED IN FISHERS, BECAUSE IN INDIANA THIS IS A COUNTY BY COUNTY ANSWER AND HAMILTON COUNTY IS ONE OF THE COUNTIES THAT IS NOT ON THE LIST. Indiana deletes the model climatic table and substitutes its own: 675 IAC 14-4.4-5 directs "Delete TABLE R301.2(1) and the corresponding footnotes and substitute to read as follows", and the substituted table then runs one row per county for all 92. One of its columns is headed "Ice Shield Underlayment Required". Fishers is in Hamilton County, which is row 29, and the entry in that column on the Hamilton County row is No. Only 27 of the 92 counties carry Yes there, and they are the northern tier, so a habit brought down from a Fort Wayne or a Lake County job is wrong here - and so is any assumption that Indiana has one statewide answer. An ice barrier can still be mandatory on a particular Fishers roof by a second and completely independent route, and the Indiana State Building Commissioner spells that route out on Department of Homeland Security letterhead. Because Sections R903.1, R904.1 and R905.1 require roofing materials to be installed in accordance with the manufacturer's installation instructions, "there are specific counties in which it is always required (per Table R301.2(1)), and specific counties in which it is required only when the roofing manufacturer's written installation instructions require it (per Sections R903.1, R904.1 and R905.1)." Hamilton County is in that second group. So on a Fishers job the question is not answered by the table alone: read the printed installation instructions for the shingle you are actually installing, because if they call for an ice barrier the code makes those instructions binding. What the barrier must be made of and how far up the slope it must run comes from the adopted 2018 International Residential Code itself, which Indiana does not modify on that point.
City of Franklin, Indiana - Building Permits and Inspections (City of Franklin, Indiana)
NOT REQUIRED BY THE TABLE IN JOHNSON COUNTY - BUT READ THE SECOND HALF OF THIS BEFORE LEAVING IT OFF. This is a county-by-county answer in Indiana. The state deletes the model climatic table and substitutes its own: 675 IAC 14-4.4-5 directs "Delete TABLE R301.2(1) and the corresponding footnotes and substitute to read as follows", and the substituted table runs one row per county. Row 41 is Johnson, and it carries "No" in the column headed "Ice Shield Underlayment Required". Twenty-seven of Indiana's ninety-two counties carry "Yes" there and they are the northern tier; Johnson County, immediately south of Marion County and Indianapolis, is not one of them, and neither is Marion. The rest of the Johnson County row is wind speed 115 mph, seismic design category B, ground snow 20 psf, foundation depth 30 inches, winter design temperature 2 degrees F and weathering Severe. THE MANUFACTURER'S INSTRUCTIONS CAN STILL REQUIRE ONE, AND THE STATE SAYS SO IN TERMS. The Indiana State Building Commissioner's Ice/Water Shield and Metal Drip Edge guidance of February 25, 2020 explains that Sections R903.1, R904.1 and R905.1 require roofing materials to be installed in accordance with the manufacturer's installation instructions, and concludes that "there are specific counties in which it is always required (per Table R301.2(1)), and specific counties in which it is required only when the roofing manufacturer's written installation instructions require it (per Sections R903.1, R904.1 and R905.1)." Johnson County is in the second group. So the correct answer on a Franklin job is to read the shingle manufacturer's published instructions for that product: if they call for an ice barrier, the code requires you to follow them, and a warranty may depend on it as well. Franklin has added nothing of its own - Title 15 of the City Code was read in full and contains no ice barrier or underlayment provision - and it could not: IC 22-13-2-3(c) bars a city, town or county from an ordinance more stringent or detailed than the state rules.
City of Greenfield Planning and Building Department (City of Greenfield, Indiana)
NOT REQUIRED BY THE TABLE IN HANCOCK COUNTY, AND THE CITY SAYS THE SAME, WITH A CONDITION. The state's Table R301.2(1), substituted by 675 IAC 14-4.4-5, runs county by county, and the Hancock row reads ice shield underlayment required No. The City's Building and Permitting page states that ice and water shield underlayment "is not required within the City of Greenfield, Indiana. However, if Ice and Water Shield Underlayment is required by the installation instructions of the shingles or roof covering to be used, it then is required to be installed". That page cites the 2005 edition of the state residential code; the current 2020 table gives the same No for Hancock. The state's own guidance explains the condition: outside the listed counties the barrier is required "only when the roofing manufacturer's written installation instructions require it". Read the shingle manufacturer's instructions for the assembly before treating the membrane as optional.
City of Greenwood, Indiana Building Commissioner (City of Greenwood, Indiana)
NOT REQUIRED BY THE TABLE IN JOHNSON COUNTY, BUT THAT IS ONLY HALF THE ANSWER, AND THE OTHER HALF CATCHES MOST GREENWOOD JOBS. In Indiana the ice barrier is a county-by-county question rather than a statewide one. The state throws out the model climatic table and substitutes its own: 675 IAC 14-4.4-5 directs "Delete TABLE R301.2(1) and the corresponding footnotes and substitute to read as follows," and the substituted table runs one row for each of the 92 counties. The Johnson County row, numbered 41, reads No in the column headed "Ice Shield Underlayment Required." Only 27 Indiana counties read Yes and they are all in the northern tier; Johnson is not one of them, and neither is any of its neighbours in the Indianapolis area. The second half comes from the Indiana State Building Commissioner, in the guidance document the City of Greenwood hosts on its own Building Codes page: "there are specific counties in which it is always required (per Table R301.2(1)), and specific counties in which it is required only when the roofing manufacturer's written installation instructions require it (per Sections R903.1, R904.1 and R905.1)." Those three sections require roof assemblies and roof coverings to be installed in accordance with the manufacturer's installation instructions, so in Johnson County an ice barrier becomes mandatory the moment the shingle you are installing calls for one in its written instructions. Read the instructions for the specific product before deciding. Where it is required, the same document gives the extent: the barrier "shall consist of not fewer than two layers of underlayment cemented together, or a self-adhering polymer-modified bitumen sheet shall be used in place of normal underlayment and extend from the lowest edges of all roof surfaces to a point not less than 24 inches (610 mm) inside the exterior wall line of the building," and on roofs of 8:12 or steeper it must also run not less than 36 inches measured along the slope from the eave edge, with an exception for "Detached accessory structures not containing conditioned floor area." Greenwood imposes nothing extra of its own.
City of Indianapolis / Marion County, Indiana - Department of Business and Neighborhood Services (BNS), Construction Services (City of Indianapolis / Marion County, Indiana)
Not categorically required in Marion County by the climatic table, but commonly required in practice by the manufacturer-instructions rule -- read both halves. STATE-GOVERNED, NOT CITY-SET. Indiana's replacement Table R301.2(1) at 675 IAC 14-4.4-5 sets "Ice Shield Underlayment Required" to "No" for Marion County (unlike, for example, Allen County / Fort Wayne, where the same table says Yes), and Indianapolis's own Homeowner's Building Permit Guide reprints that "No" in its Marion County table row. The Indiana State Building Commissioner's guidance memo "Ice/Water Shield & Metal Drip Edge in Class 2 Construction with Asphalt Shingles" (2020-02-25) is explicit that two layers of rule combine: "there are specific counties in which it is always required (per Table R301.2(1)), and specific counties in which it is required only when the roofing manufacturer's written installation instructions require it (per Sections R903.1, R904.1 and R905.1)." Marion County is in the second group: the table does not mandate an ice barrier, but IRC R903.1/R904.1/R905.1 independently require roof coverings to be installed per the manufacturer's written installation instructions, and where those instructions call for an ice barrier in a central-Indiana climate it becomes mandatory on that job. Where an ice barrier is triggered, the unamended 2018 IRC R905.1.2 extent applies: "The ice barrier shall consist of not fewer than two layers of underlayment cemented together, or a self-adhering polymer-modified bitumen sheet ... and extend from the lowest edges of all roof surfaces to a point not less than 24 inches inside the exterior wall line of the building. ... Exception: Detached accessory structures not containing conditioned floor area."
City of Jasper Department of Community Development & Planning (City of Jasper, Indiana)
NOT REQUIRED BY THE TABLE IN DUBOIS COUNTY, AND THE MANUFACTURER'S INSTRUCTIONS CAN STILL REQUIRE IT. The Indiana Residential Code's Table R301.2(1) runs county by county, and its Dubois County row reads Ice Shield Underlayment Required: No. The state memo explains what that No means: "there are specific counties in which it is always required (per Table R301.2(1)), and specific counties in which it is required only when the roofing manufacturer's written installation instructions require it (per Sections R903.1, R904.1 and R905.1)." So where the shingle maker's instructions call for an ice barrier on the assembly being installed, the code requires it on the job. WATCH THE NAME. The same table has a separate row for Jasper County, a different county in northwest Indiana, and that row reads Yes. The City of Jasper is in Dubois County, so the Jasper County row does not apply here. Jasper's own code contains no ice-barrier provision.
City of Jeffersonville, Indiana - Building Commission (City of Jeffersonville, Indiana)
NOT REQUIRED BY THE TABLE IN CLARK COUNTY - BUT READ THE SECOND HALF OF THIS BEFORE LEAVING IT OFF. This is a county-by-county answer in Indiana. The state deletes the model climatic table and substitutes its own: 675 IAC 14-4.4-5 directs "Delete TABLE R301.2(1) and the corresponding footnotes and substitute to read as follows", and the substituted table runs one row per county. Row 10 is Clark, and it carries "No" in the column headed "Ice Shield Underlayment Required". Twenty-seven of Indiana's ninety-two counties carry "Yes" there and they are the northern tier; Clark County, on the Ohio River opposite Louisville, is at the opposite end of the state and is not one of them. The rest of the Clark County row is wind speed 115 mph, seismic design category B, ground snow 20 psf, foundation depth 24 inches, winter design temperature 9 degrees F and weathering Severe. THE MANUFACTURER'S INSTRUCTIONS CAN STILL REQUIRE ONE, AND THE STATE SAYS SO IN TERMS. The Indiana State Building Commissioner's Ice/Water Shield and Metal Drip Edge guidance of February 25, 2020 explains that Sections R903.1, R904.1 and R905.1 require roofing materials to be installed in accordance with the manufacturer's installation instructions, and concludes that "there are specific counties in which it is always required (per Table R301.2(1)), and specific counties in which it is required only when the roofing manufacturer's written installation instructions require it (per Sections R903.1, R904.1 and R905.1)." Clark County is in the second group. So the correct answer on a Jeffersonville job is to read the shingle manufacturer's published instructions for that product: if they call for an ice barrier, the code requires you to follow them, and a warranty may depend on it as well. Jeffersonville could not add a requirement of its own in any event, because IC 22-13-2-3(c) bars a city, town or county from an ordinance more stringent or detailed than the state rules.
City of Kokomo, Indiana Inspection Services Department (City of Kokomo, Indiana)
NOT REQUIRED BY THE TABLE IN HOWARD COUNTY, BUT THAT IS ONLY HALF THE ANSWER, AND THE OTHER HALF CATCHES A LOT OF KOKOMO JOBS. In Indiana the ice barrier is a county-by-county question rather than a statewide one. The state throws out the model climatic table and substitutes its own: 675 IAC 14-4.4-5 directs "Delete TABLE R301.2(1) and the corresponding footnotes and substitute to read as follows," and the substituted table runs one row for each of the 92 counties. The Howard County row, numbered 34, reads No in the column headed "Ice Shield Underlayment Required." Kokomo lies wholly within Howard County, so there is only one row to read. Only 27 Indiana counties read Yes and they are the northern tier; Howard is not one of them, but Cass, Carroll and Miami all are, so a crew that works across the county line to the north or west can be on the other answer on the same week. The second half comes from the Indiana State Building Commissioner, in published guidance on ice/water shield and drip edge: "there are specific counties in which it is always required (per Table R301.2(1)), and specific counties in which it is required only when the roofing manufacturer's written installation instructions require it (per Sections R903.1, R904.1 and R905.1)." Those three sections require roof assemblies and roof coverings to be installed in accordance with the manufacturer's installation instructions, so in Howard County an ice barrier becomes mandatory the moment the shingle you are installing calls for one in its written instructions. Read the instructions for the specific product before deciding. Where it is required, the same document gives the extent: the barrier "shall consist of not fewer than two layers of underlayment cemented together, or a self-adhering polymer-modified bitumen sheet shall be used in place of normal underlayment and extend from the lowest edges of all roof surfaces to a point not less than 24 inches (610 mm) inside the exterior wall line of the building," and on roofs of 8:12 or steeper it must also run not less than 36 inches measured along the roof slope from the eave edge, with an exception for "Detached accessory structures not containing conditioned floor area." Kokomo imposes nothing extra of its own.
City of Lafayette Office of the City Engineer (City of Lafayette, Indiana)
Not required by the climatic table in Tippecanoe County. Indiana replaces the model Table R301.2(1) with its own county-by-county table at 675 IAC 14-4.4-5, and the Tippecanoe County row carries "No" in the column headed "Ice Shield Underlayment Required". Twenty-seven of Indiana's ninety-two counties carry "Yes" there, and they are the northern tier. Tippecanoe County sits right on that line, which is the thing to watch on a job just outside the city: of the seven counties bordering it, Benton to the northwest, White to the north and Carroll to the northeast are all "Yes", while Warren, Fountain, Montgomery and Clinton are "No" like Tippecanoe itself. A roofer crossing the county line north of Lafayette can be on a different answer for the same detail. This is a state answer that Lafayette has no power to change, because IC 22-13-2-3(c) bars a local ordinance more stringent or more detailed than the state building rules. The table is not the only route to an ice barrier on a particular job, though: roof coverings must still go on to the manufacturer's instructions, and where those call for one on a given assembly, that governs the installation.
City of Lawrence, Indiana - Building Department (City of Lawrence, Indiana)
NOT REQUIRED BY THE TABLE IN MARION COUNTY - BUT READ THE SECOND HALF OF THIS, BECAUSE THE MANUFACTURER CAN STILL REQUIRE IT. Indiana deletes the model climatic table and substitutes its own county-by-county table: 675 IAC 14-4.4-5 directs "Delete TABLE R301.2(1) and the corresponding footnotes and substitute to read as follows", and the substituted table runs one row per county. Row 49 is Marion, and it carries "No" in the column headed "Ice Shield Underlayment Required". Twenty-seven of Indiana's ninety-two counties carry "Yes" there and they are the northern tier; Marion is not one of them, so an answer carried down from a South Bend or Fort Wayne job would be wrong here. The rest of the Marion County row reads wind speed 115 mph, seismic design category B, ground snow 20 psf, foundation depth 30 inches, winter design temperature 2 degrees F and weathering Severe. The Indiana State Building Commissioner sets out the important qualification in terms: Sections R903.1, R904.1 and R905.1 require roofing materials to be installed in accordance with the manufacturer's installation instructions, so "there are specific counties in which it is always required (per Table R301.2(1)), and specific counties in which it is required only when the roofing manufacturer's written installation instructions require it (per Sections R903 .1, R904.1 and R905 .1)." Marion County is in that second group: the table does not compel an ice barrier, and the shingle manufacturer's printed instructions still can. The City's own roofing handout says the same thing in one line under UNDERLAYMENT: "Note: For ice barrier materials, the manufacturer's installation instructions must be followed." Lawrence has no power to add a requirement of its own, because IC 22-13-2-3(c) bars a city, town or county from an ordinance more stringent or detailed than the state rules.
City of Lebanon Planning Department (City of Lebanon, Indiana)
NOT REQUIRED BY THE TABLE IN BOONE COUNTY, AND THAT IS NOT THE END OF THE QUESTION. Table R301.2(1) of the 2020 Indiana Residential Code, as substituted by 675 IAC 14-4.4-5, runs county by county, and the Boone County row reads ice shield underlayment required No. The State Building Commissioner's memorandum explains what that No means: there are counties where the barrier is always required by the table, and "specific counties in which it is required only when the roofing manufacturer's written installation instructions require it", because sections R903.1, R904.1 and R905.1 require roofing to be installed in accordance with the manufacturer's installation instructions. So on a Lebanon job the membrane is required wherever the shingle manufacturer's written instructions call for it on the assembly being installed. None of the Lebanon instruments read for this record touches ice barriers. The City's 2013 adopting ordinance lists the 2003 International Residential Code, and the City has published no statement of which edition it enforces; this answer is the 2020 Indiana Residential Code's.
City of Madison, Indiana - Building and Design Division (City of Madison, Indiana)
NOT REQUIRED BY THE TABLE IN JEFFERSON COUNTY, BUT THE SHINGLE MANUFACTURER CAN STILL REQUIRE ONE. Indiana deletes the model climatic table and substitutes its own, one row per county: 675 IAC 14-4.4-5 directs "Delete TABLE R301.2(1) and the corresponding footnotes and substitute to read as follows". Row 39 is Jefferson, and it carries "No" in the column headed "Ice Shield Underlayment Required". Twenty-seven of the ninety-two county rows carry "Yes" in that column, and Jefferson is not one of them. The rest of the Jefferson row gives wind speed 115 mph, seismic design category B, ground snow 20 psf, foundation depth 24 inches, a winter design temperature of 9 degrees F and Severe weathering. Section R905.1.2, as the State Building Commissioner's ice/water shield and drip edge guidance sets it out, calls for an ice barrier "In areas where there has been a history of ice forming along the eaves causing a backup of water as designated in Table R301.2(1)", so the table decides it. THE MANUFACTURER'S INSTRUCTIONS ARE THE SECOND TEST, and the same guidance says so in terms: Sections R903.1, R904.1 and R905.1 require roofing materials to be installed in accordance with the manufacturer's installation instructions, and "there are specific counties in which it is always required (per Table R301.2(1)), and specific counties in which it is required only when the roofing manufacturer's written installation instructions require it (per Sections R903.1, R904.1 and R905.1)." Jefferson County is in the second group, so read the shingle manufacturer's published instructions for the product on the job: if they call for an ice barrier, the code requires it. Madison's Building Code chapter contains no ice barrier or underlayment provision, and IC 22-13-2-3(c) bars a city from adding one.
City of Muncie, IN - Building Commissioner's Office (City of Muncie, Indiana)
Not required by the climatic table in Delaware County. Indiana deletes the model Table R301.2(1) and substitutes its own county-by-county table at 675 IAC 14-4.4-5, and the Delaware County row states "No" in the column headed "Ice Shield Underlayment Required". Twenty-seven of Indiana's 92 counties, all in the northern tier, are marked "Yes"; Delaware County, in the east-central part of the state, is not one of them. This is a state answer that Muncie has no power to change, because IC 22-13-2-3 bars a local ordinance more stringent or more detailed than the state building rules. Note that the table is not the only route to an ice barrier on a particular job - roof coverings still have to be installed to the manufacturer's instructions, and where those instructions call for one it governs that installation.
City of New Albany Building Department (City of New Albany, Indiana)
NOT REQUIRED BY THE TABLE IN FLOYD COUNTY, AND THAT IS NOT THE END OF THE QUESTION. The Indiana Residential Code's Table R301.2(1), amended by 675 IAC 14-4.4-5, runs county by county, and the Floyd row reads: wind speed 115, seismic design category B, ground snow load 20, frost depth 24, winter design temperature 9 degrees, decay slight to moderate, termite moderate to heavy, weathering severe, ice shield underlayment required No, air freezing index 1500 or less, mean annual temperature 54.7 degrees. WHAT THE STATE'S OWN MEMO SAYS THE No MEANS. It means only that Floyd is not one of the counties where the barrier is always required; R903.1, R904.1 and R905.1 still require roofing to be installed in accordance with the manufacturer's installation instructions, so where those instructions call for an ice-and-water membrane on a given assembly, that requirement governs the job regardless of the table. New Albany has no ordinance touching this: its building-code sections 150.001 through 150.086 contain no ice barrier, underlayment or climatic provision, and IC 22-13-2-3(c) bars it from adding one. Read the shingle manufacturer's instructions for the assembly being installed before treating the membrane as optional here.
City of Noblesville, Indiana - Department of Planning and Development, Building Division (City of Noblesville, Indiana)
NOT CATEGORICALLY REQUIRED HERE, AND IN INDIANA THIS IS A COUNTY-BY-COUNTY ANSWER RATHER THAN A STATE ONE. Indiana throws out the model climatic table and substitutes its own: 675 IAC 14-4.4-5 directs "Delete TABLE R301.2(1) and the corresponding footnotes and substitute to read as follows," and the substituted table then runs one row per county for all 92. Noblesville is in Hamilton County, and row 29 of that table reads "No" in the column headed "Ice Shield Underlayment Required." Only 27 Indiana counties, almost all of them in the northern tier, read "Yes"; the other 65 read "No", so a rule of thumb carried down from Fort Wayne or up from a lake-effect county is wrong in Noblesville, and so is any assumption that Indiana has a single statewide answer. An ice barrier can still be mandatory on a particular Noblesville job by a second, independent route, which the Indiana State Building Commissioner sets out on Department of Homeland Security letterhead: because Sections R903.1, R904.1 and R905.1 require roofing materials to be installed in accordance with the manufacturer's installation instructions, "there are specific counties in which it is always required (per Table R301.2(1)), and specific counties in which it is required only when the roofing manufacturer's written installation instructions require it (per Sections R903.1, R904.1 and R905.1)." Hamilton County sits in that second group, so read the printed installation instructions for the shingle you are actually installing before deciding. What the barrier must be made of and how far up the slope it must run is base International Residential Code content that Indiana does not modify; take it from the adopted 2018 edition rather than from a neighbouring state.
City of Richmond, Indiana - Permits and Inspections (City of Richmond, Indiana)
NOT REQUIRED BY THE TABLE IN WAYNE COUNTY - BUT READ THE SECOND HALF OF THIS BEFORE LEAVING IT OFF. This is a county-by-county answer in Indiana. The state deletes the model climatic table and substitutes its own: 675 IAC 14-4.4-5 directs "Delete TABLE R301.2(1) and the corresponding footnotes and substitute to read as follows", and the substituted table runs one row per county. Row 89 is Wayne, and it carries "No" in the column headed "Ice Shield Underlayment Required". Twenty-seven of Indiana's ninety-two counties carry "Yes" there and they are the northern tier; Wayne County, on the Ohio line east of Indianapolis, is not one of them. The rest of the Wayne County row is wind speed 115 mph, seismic design category A, ground snow 20 psf, foundation depth 30 inches, winter design temperature 2 degrees F and weathering Severe. THE MANUFACTURER'S INSTRUCTIONS CAN STILL REQUIRE ONE, AND THE STATE SAYS SO IN TERMS. The Indiana State Building Commissioner's Ice/Water Shield and Metal Drip Edge guidance of February 25, 2020 explains that Sections R903.1, R904.1 and R905.1 require roofing materials to be installed in accordance with the manufacturer's installation instructions, and concludes that "there are specific counties in which it is always required (per Table R301.2(1)), and specific counties in which it is required only when the roofing manufacturer's written installation instructions require it (per Sections R903.1, R904.1 and R905.1)." Wayne County is in the second group. So the correct answer on a Richmond job is to read the shingle manufacturer's published instructions for that product: if they call for an ice barrier, the code requires you to follow them, and a warranty may depend on it as well. Richmond has added nothing of its own - Chapter 150 of the City Code was read in full and contains no ice barrier or underlayment provision - and it could not: IC 22-13-2-3(c) bars a city, town or county from an ordinance more stringent or detailed than the state rules.
City of Seymour Planning and Zoning Department (City of Seymour, Indiana)
NOT REQUIRED BY THE TABLE IN JACKSON COUNTY, BUT THE MANUFACTURER CAN STILL REQUIRE IT. Indiana replaces the model climatic table with its own county by county one: 675 IAC 14-4.4-5 directs "Delete TABLE R301.2(1) and the corresponding footnotes and substitute to read as follows". Row 36, Jackson, carries "No" in the column headed Ice Shield Underlayment Required. Allen, Elkhart and Jasper counties, among others, carry Yes, so an answer carried down from a northern Indiana job would be wrong here. The State Building Commissioner's guidance explains what the No leaves in place: "there are specific counties in which it is always required (per Table R301.2(1)), and specific counties in which it is required only when the roofing manufacturer's written installation instructions require it (per Sections R903.1, R904.1 and R905.1)." Jackson County is in the second group, so read the shingle manufacturer's printed instructions for the assembly before leaving the membrane out. Seymour's building chapter has since been read in full, all forty-four sections of Municipal Code Chapter 151, and "ice barrier", "ice and water" and "ice shield" each occur zero times in it; IC 22-13-2-3(c) bars the City from adding a rule of its own in any event.
City of Shelbyville Planning and Building Department (City of Shelbyville, Indiana)
NOT REQUIRED BY THE TABLE, AND THE CITY SAYS SO IN TERMS, BUT READ THE MANUFACTURER'S INSTRUCTIONS. The City's Building Codes page states: "Shelbyville does not require ice shield underlayment on a roof, but it is highly recommended." The state table agrees: the Shelby County row of Table R301.2(1) in the 2020 Indiana Residential Code reads ice shield underlayment required No. WHAT THAT No MEANS, IN THE STATE'S OWN WORDS. The State Building Commissioner's memo explains that R903.1, R904.1 and R905.1 require roofing to be installed to the manufacturer's installation instructions, so there are counties where the barrier is always required and "specific counties in which it is required only when the roofing manufacturer's written installation instructions require it". Shelby County is in the second group. If the shingle manufacturer's instructions for the assembly being installed call for an ice and water membrane, the code requires it on that job.
City of Terre Haute Department of Engineering - Building Inspection Division (City of Terre Haute, Indiana)
Not required by the climatic table in Vigo County. Indiana deletes the model Table R301.2(1) and substitutes its own county-by-county table at 675 IAC 14-4.4-5, and the Vigo County row is marked "No" in the column headed "Ice Shield Underlayment Required". Twenty-seven of Indiana's 92 counties, all in the northern tier, are marked "Yes"; Vigo, on the western edge of the state roughly halfway down, is not one of them, and neither is any county bordering it. This is a state answer Terre Haute has no power to change, because IC 22-13-2-3 bars a local ordinance more stringent or more detailed than the state building rules, and nothing in the City Code addresses ice barriers. The table is not the only route to an ice barrier on a particular job - roof coverings must still be installed to the manufacturer's instructions, and where those instructions call for one it governs that installation.
City of Vincennes, Indiana City Inspector's Office (City of Vincennes, Indiana)
NOT REQUIRED BY THE TABLE IN KNOX COUNTY, BUT THE SHINGLE INSTRUCTIONS CAN STILL REQUIRE ONE. In Indiana the ice barrier is a county-by-county answer. The state deletes the model climatic table and substitutes its own at 675 IAC 14-4.4-5, one row per county, and row 42 is Knox, which reads No in the column headed "Ice Shield Underlayment Required." Vincennes is the Knox County seat, so that is the row to read. The Indiana State Building Commissioner's guidance of February 25, 2020 supplies the other half: "In short, there are specific counties in which it is always required (per Table R301.2(1)), and specific counties in which it is required only when the roofing manufacturer's written installation instructions require it (per Sections R903.1, R904.1 and R905.1)." Knox County is in the second group, so read the written installation instructions for the specific shingle before leaving the barrier off; if they call for one, the code requires it. Where it is required, the same guidance gives the extent: the ice barrier "shall consist of not fewer than two layers of underlayment cemented together, or a self-adhering polymer-modified bitumen sheet shall be used in place of normal underlayment and extend from the lowest edges of all roof surfaces to a point not less than 24 inches (610 mm) inside the exterior wall line of the building", and on roofs of 8:12 or steeper it "shall also be applied not less than 36 inches (914 mm) measured along the roof slope from the eave edge of the building", with an exception for "Detached accessory structures not containing conditioned floor area." Chapter 150 of the Vincennes Code of Ordinances was read in full and adds nothing on underlayment. Vincennes has published no statement of which residential edition it enforces, and the Article 14 list in City Code 150.19 still names the CABO One and Two Family Dwelling Code, whose text has not been read for this record; this answer is the 2020 Indiana Residential Code's.
City of West Lafayette Building Department (City of West Lafayette, Indiana)
NOT REQUIRED BY THE TABLE HERE, AND THAT IS NOT THE END OF THE QUESTION. The Indiana Residential Code's Table R301.2(1) runs county by county, and the Tippecanoe row reads wind speed 115, seismic A, ground snow load 20, frost depth 30, winter design temperature 2 degrees, decay slight to moderate, termite moderate to heavy, weathering severe, ice shield underlayment required No, air freezing index 2000, mean annual temperature 50.9. WHAT THE STATE'S OWN MEMO SAYS THE No MEANS. It means only that Tippecanoe is not on the list of counties where the barrier is mandatory; R903.1, R904.1 and R905.1 still require roofing to be installed in accordance with the manufacturer's installation instructions, so where those instructions call for an ice-and-water membrane on a given assembly, that requirement governs the job regardless of the table. West Lafayette has no ordinance touching this: Chapter 6 contains no occurrence of ice, snow, seismic or wind speed at all. Read the shingle manufacturer's instructions for the assembly being installed before deciding the membrane is optional here.
City of Westfield, Indiana - Community Development Department, Building Division (City of Westfield, Indiana)
NOT CATEGORICALLY REQUIRED HERE, AND IN INDIANA THIS IS A COUNTY-BY-COUNTY ANSWER RATHER THAN A STATE ONE. Indiana throws out the model climatic table and substitutes its own: 675 IAC 14-4.4-5 directs "Delete TABLE R301.2(1) and the corresponding footnotes and substitute to read as follows," and the substituted table then runs one row per county for all 92. Westfield is in Hamilton County, whose row is number 29, and that row carries "No" in the column headed "Ice Shield Underlayment Required". Only 27 of the 92 Indiana counties carry "Yes" in that column, and they are the northern tier; the other 65 carry "No". So a rule of thumb carried down from Fort Wayne or across from a lake-effect county is wrong in Westfield, and so is any assumption that Indiana has a single statewide answer. An ice barrier can still be mandatory on a particular Westfield job by a second and independent route, which the Indiana State Building Commissioner sets out on Department of Homeland Security letterhead: because Sections R903.1, R904.1 and R905.1 require roofing materials to be installed in accordance with the manufacturer's installation instructions, "there are specific counties in which it is always required (per Table R301.2(1)), and specific counties in which it is required only when the roofing manufacturer's written installation instructions require it (per Sections R903.1, R904.1 and R905.1)." Hamilton County sits in that second group, so read the printed installation instructions for the shingle you are actually installing before deciding. Westfield has published exactly this answer for itself. Its Roofing FAQ asks "Does Westfield require ice and water shield if the manufacturer does not?" and answers "Westfield does not impose additional ice and water shield requirements beyond what is required by the current Indiana Residential Code," then asks "If the manufacturer requires ice and water shield, does Westfield require it to be installed?" and answers "Yes. Manufacturer installation instructions must be followed." It closes the loop with "Is failure to follow manufacturer installation instructions considered a code violation? Yes."
Clark County, Indiana - Planning and Zoning (Building Commissioner) (Clark County, Indiana (unincorporated areas and the Town of Borden))
NOT REQUIRED BY THE TABLE IN CLARK COUNTY, BUT READ THE REST OF THIS BEFORE LEAVING IT OFF. Indiana deletes the model climatic table and substitutes its own, one row per county: 675 IAC 14-4.4-5 directs "Delete TABLE R301.2(1) and the corresponding footnotes and substitute to read as follows". Row 10 is Clark, and its entry in the column headed Ice Shield Underlayment Required is No. The state's guidance explains what that No means. The Indiana State Building Commissioner's ice and water shield and drip edge guidance of February 25, 2020 points out that the code requires roofing to be installed to the manufacturer's instructions and concludes that "there are specific counties in which it is always required (per Table R301.2(1)), and specific counties in which it is required only when the roofing manufacturer's written installation instructions require it (per Sections R903.1, R904.1 and R905.1)." Clark County is in the second group. So read the shingle manufacturer's published instructions for the product being installed: if they call for an ice barrier, the code requires you to follow them. The County has no ordinance of its own on this, and IC 22-13-2-3(c) bars a county from one more stringent than the state rule.
Delaware County Building Commissioner's Office (Delaware County, Indiana)
NOT REQUIRED BY THE TABLE IN DELAWARE COUNTY, AND THAT IS NOT THE END OF THE QUESTION. Indiana deletes the model Table R301.2(1) and substitutes its own county-by-county table at 675 IAC 14-4.4-5, and the Delaware County row prints No in the ice shield underlayment column. The State Building Commissioner's memo that reproduces the table makes the point that the table is not the only route to the membrane: R903.1, R904.1 and R905.1 still require roofing to be installed in accordance with the manufacturer's installation instructions, so where those instructions call for an ice-and-water membrane on the assembly being installed, that requirement applies to the job regardless of the table. Delaware County has no ordinance on the point; Title 4 contains no occurrence of ice, snow or wind. Read the shingle manufacturer's instructions before treating the membrane as optional here.
Evansville-Vanderburgh County Building Commission (City of Evansville / Vanderburgh County, Indiana)
Not required by the climatic table in Vanderburgh County. Indiana deletes the model Table R301.2(1) and substitutes its own county-by-county table at 675 IAC 14-4.4-5, and the Vanderburgh County row states "No" in the column headed "Ice Shield Underlayment Required". Twenty-seven of Indiana's 92 counties, all in the northern tier, are marked "Yes"; Vanderburgh, in the far southwest of the state, is not one of them. This is a state answer that Evansville and Vanderburgh County have no power to change, since IC 22-13-2-3 bars a local ordinance more stringent or more detailed than the state building rules. Note that the table is not the only route to an ice barrier on a particular job - roof coverings must still be installed to the manufacturer's instructions, and where those instructions call for one it governs that installation.
Fayette County, Indiana - Area Plan Commission (Fayette County, Indiana (the unincorporated county and the City of Connersville))
NOT REQUIRED BY THE TABLE IN FAYETTE COUNTY, BUT THE SHINGLE MANUFACTURER CAN STILL REQUIRE IT. Indiana deletes the model climatic table and substitutes its own county-by-county table: 675 IAC 14-4.4-5 directs "Delete TABLE R301.2(1) and the corresponding footnotes and substitute to read as follows", and the substituted table runs one row per county. Row 21 is Fayette, and it carries "No" in the column headed "Ice Shield Underlayment Required". Twenty-seven of Indiana's ninety-two counties carry "Yes" there and Fayette is not one of them. The Indiana State Building Commissioner sets out the qualification in the February 25, 2020 guidance on Indiana Department of Homeland Security letterhead: Sections R903.1, R904.1 and R905.1 require roofing to be installed in accordance with the manufacturer's installation instructions, so "there are specific counties in which it is always required (per Table R301.2(1)), and specific counties in which it is required only when the roofing manufacturer's written installation instructions require it (per Sections R903.1, R904.1 and R905.1)." Fayette County is in the second group: the table does not compel an ice barrier here, and the shingle manufacturer's printed instructions still can. IC 22-13-2-3(c) bars a city, town or county from an ordinance more stringent or detailed than the state rules.
Floyd County Department of Building and Development Services (Floyd County, Indiana)
NOT REQUIRED BY THE STATE TABLE FOR FLOYD COUNTY, AND THAT IS NOT THE END OF THE QUESTION. The Indiana Residential Code's Table R301.2(1) is amended by 675 IAC 14-4.4-5 to run county by county, and the Floyd County row, read from the rendered table in the State Building Commissioner's memo, prints No in the ice shield underlayment column. WHAT THE No MEANS. The memo explains that the table lists the counties where the barrier is always required, while R903.1, R904.1 and R905.1 "further require that all roofing materials be installed in accordance with the manufacturer's installation instructions". So in a No county such as Floyd the membrane is required wherever the shingle manufacturer's written installation instructions call for it on the assembly being installed. Floyd County has no ice barrier or underlayment provision of its own. Read the manufacturer's instructions before treating the membrane as optional here.
Grant County Area Plan Department (Grant County, Indiana)
NOT REQUIRED BY THE TABLE HERE, AND THE COUNTY SAYS THE SAME, WITH ONE CONDITION. The Indiana Residential Code's Table R301.2(1), as amended by 675 IAC 14-4.4-5, runs county by county, and the Grant County row prints No in the ice shield underlayment column. The Area Plan Department's own guidance agrees: "According to Indiana code, in Grant County ice protection is NOT required; unless the shingle material's manufacturing instructions calls for it (which supersedes Indiana code)." The State Building Commissioner's memo explains how that works: "Note that the table lists specific Indiana counties in which the use of ice/water shield is required", and elsewhere the membrane is required "only when the roofing manufacturer's written installation instructions require it". INSIDE THE CITY OF MARION THE ANSWER IS DIFFERENT: the City's Building Department requires ice and water shield and inspects for it at the tear-off, so a job inside the city limits is held to the City's own standard; see this directory's Marion record. Read the shingle manufacturer's instructions for the assembly being installed before deciding the membrane is optional on a Grant County job.
Greencastle Building Division (City of Greencastle, Indiana)
NOT REQUIRED BY THE STATE TABLE FOR PUTNAM COUNTY, BUT READ THE MANUFACTURER'S INSTRUCTIONS. The Putnam County row of Table R301.2(1) in the 2020 Indiana Residential Code, as substituted by 675 IAC 14-4.4-5, reads ice shield underlayment required No. That row was read from the rendered table rather than from extracted text, because the table's termite column drops out of extraction and the columns shift when it does. WHAT THAT No MEANS, IN THE STATE'S OWN WORDS. The State Building Commissioner's memo explains that Sections R903.1, R904.1 and R905.1 require roofing to be installed to the manufacturer's installation instructions, so there are counties where the barrier is always required and "specific counties in which it is required only when the roofing manufacturer's written installation instructions require it". Putnam County is in the second group. If the shingle manufacturer's instructions for the assembly being installed call for an ice and water membrane, the code requires it on that job. Greencastle's Chapter 7 says nothing either way: "ice barrier", "ice and water" and "ice shield" each occur zero times in it.
Hamilton County, Indiana - Hamilton County Plan Commission (Planning Department) (Hamilton County, Indiana)
NOT CATEGORICALLY REQUIRED HERE, AND IN INDIANA THIS IS A COUNTY BY COUNTY ANSWER RATHER THAN A STATE ONE. Indiana throws out the model climatic table and substitutes its own: 675 IAC 14-4.4-5 directs "Delete TABLE R301.2(1) and the corresponding footnotes and substitute to read as follows," and the substituted table then runs one row per county for all 92. Hamilton County is row 29, and that row carries "No" in the column headed "Ice Shield Underlayment Required." Only 27 Indiana counties, almost all of them in the northern tier, carry "Yes" in that column; the other 65 carry "No", so a rule of thumb carried down from Fort Wayne or from a lake effect county is wrong in Hamilton County, and so is any assumption that Indiana has a single statewide answer. An ice barrier can still be mandatory on a particular job here by a second, independent route, which the Indiana State Building Commissioner sets out on Department of Homeland Security letterhead: because Sections R903.1, R904.1 and R905.1 require roofing materials to be installed in accordance with the manufacturer's installation instructions, "there are specific counties in which it is always required (per Table R301.2(1)), and specific counties in which it is required only when the roofing manufacturer's written installation instructions require it (per Sections R903.1, R904.1 and R905.1)." Hamilton County sits in that second group, so read the printed installation instructions for the shingle you are actually installing before deciding. What the barrier must be made of and how far up the slope it must run is base International Residential Code content that Indiana does not modify; take it from the adopted 2018 edition rather than from a neighbouring state.
Hendricks County, Indiana - Planning and Building Department (Hendricks County, Indiana)
NOT REQUIRED BY THE TABLE IN HENDRICKS COUNTY - AND THIS IS A COUNTY-BY-COUNTY ANSWER IN INDIANA, NOT A STATE ONE. Indiana deletes the model climatic table and substitutes its own: 675 IAC 14-4.4-5 directs "Delete TABLE R301.2(1) and the corresponding footnotes and substitute to read as follows", and the substituted table runs one row per county. Row 32 is Hendricks, and it carries "No" in the column headed "Ice Shield Underlayment Required". Twenty-seven of Indiana's ninety-two counties carry "Yes" there and they are the northern tier; the other sixty-five, Hendricks among them, carry "No". The rest of the Hendricks County row reads wind speed 115 mph, seismic design category B, ground snow 20 psf, foundation depth 30 inches, winter design temperature 2 degrees, decay Slight to Moderate, termite Moderate to Heavy, weathering Severe and mean annual temperature 52.3 degrees. THE PART A ROOFER MUST NOT SKIP. A "No" in that column does not mean an ice barrier is never required on a Hendricks County roof. The Indiana State Building Commissioner's Ice/Water Shield and Metal Drip Edge guidance of February 25, 2020 states that "there are specific counties in which it is always required (per Table R301.2(1)), and specific counties in which it is required only when the roofing manufacturer's written installation instructions require it". Hendricks County is in the second group. So the question on an ordinary Hendricks County job is what the shingle manufacturer's printed installation instructions say - read them before deciding, because they, not the table, carry the answer here. Neighbouring Marion, Boone, Morgan, Montgomery and Putnam Counties all read "No" as well, so the whole Indianapolis-west corridor is consistent on this point; the "Yes" counties begin well to the north. Hendricks County Building Code Ordinance No. 2022-29 was read in full and adds nothing on the point, and could not: IC 22-13-2-3(c) bars a more stringent or more detailed local requirement.
Howard County, Indiana - Kokomo-Howard County Plan Commission (Howard County, Indiana)
NOT REQUIRED BY THE TABLE IN HOWARD COUNTY, BUT THE SHINGLE'S OWN INSTRUCTIONS CAN MAKE IT REQUIRED. In Indiana the ice barrier is decided county by county. 675 IAC 14-4.4-5 deletes the model climatic table and substitutes the state's own, one row for each of the 92 counties, and the Howard County row, numbered 34, reads No in the ice shield underlayment column. The Indiana State Building Commissioner's published guidance supplies the other half: "there are specific counties in which it is always required (per Table R301.2(1)), and specific counties in which it is required only when the roofing manufacturer's written installation instructions require it (per Sections R903.1, R904.1 and R905.1)." So in Howard County the ice barrier becomes mandatory when the written installation instructions for the product being installed call for one; read them for the specific shingle before deciding. The neighboring counties split: Cass, Carroll and Miami read Yes, while Tipton, Clinton and Grant read No, so a crew working across the county line to the north or west can be on the other answer. Where it is required, the same guidance gives the extent, including a point "not less than 24 inches (610 mm) inside the exterior wall line of the building". The County's Chapter 150, read in full, says nothing on ice barriers. The County's code book names the 1976 One- and Two-Family Dwelling Code rather than the 2020 Indiana Residential Code; that older text was not read, and the County has published no statement of which edition it enforces.
Johnson County Department of Planning and Zoning - Building Department (Johnson County, Indiana (unincorporated areas))
NOT REQUIRED BY THE TABLE IN JOHNSON COUNTY, AND THAT IS ONLY HALF THE ANSWER. Indiana replaces the model climatic table with its own: 675 IAC 14-4.4-5 directs "Delete TABLE R301.2(1) and the corresponding footnotes and substitute to read as follows", and the substituted table runs one row per county. Row 41, Johnson, reads No in the column headed Ice Shield Underlayment Required. THE MANUFACTURER'S INSTRUCTIONS CAN STILL MAKE IT MANDATORY, AND THE STATE SAYS SO. The Indiana State Building Commissioner's guidance of February 25, 2020 explains that "there are specific counties in which it is always required (per Table R301.2(1)), and specific counties in which it is required only when the roofing manufacturer's written installation instructions require it (per Sections R903.1, R904.1 and R905.1)." Johnson County is in the second group, so read the written instructions for the specific shingle being installed: where they call for an ice barrier, the code requires it here. The County's Building Code article contains no occurrence of ice or snow and adds nothing of its own, and IC 22-13-2-3(c) bars it from doing so.
Madison County Planning Department (Madison County, Indiana)
NOT REQUIRED BY THE TABLE IN MADISON COUNTY, AND THE SHINGLE MANUFACTURER CAN STILL REQUIRE IT. Indiana replaces the model climatic table with its own county-by-county table: 675 IAC 14-4.4-5 directs "Delete TABLE R301.2(1) and the corresponding footnotes and substitute to read as follows". Row 48 is Madison, and it reads "No" in the column headed Ice Shield Underlayment Required. Other Indiana counties carry "Yes" in that column, so an answer brought over from a job in one of them can be wrong here. The State Building Commissioner's guidance explains what the No means. Roofing must be installed to the manufacturer's installation instructions under Sections R903.1, R904.1 and R905.1, so "there are specific counties in which it is always required (per Table R301.2(1)), and specific counties in which it is required only when the roofing manufacturer's written installation instructions require it (per Sections R903.1, R904.1 and R905.1)." Madison County is in the second group. Read the shingle manufacturer's instructions for the assembly before treating the membrane as optional. The County publishes no ice barrier rule of its own, and IC 22-13-2-3(c) bars it from adding one.
Martinsville Building and Planning Department (City of Martinsville, Indiana)
NOT REQUIRED BY THE STATE TABLE FOR MORGAN COUNTY, BUT READ THE MANUFACTURER'S INSTRUCTIONS. The Morgan County row of Table R301.2(1) in the 2020 Indiana Residential Code, as substituted by 675 IAC 14-4.4-5, reads ice shield underlayment required No. That row was read from the rendered table rather than from extracted text, because the table's termite column drops out of extraction and every column to its right then reads one place out. WHAT THAT No MEANS, IN THE STATE'S OWN WORDS. The State Building Commissioner's memo explains that Sections R903.1, R904.1 and R905.1 require roofing to be installed to the manufacturer's installation instructions, so there are counties where the barrier is always required and "specific counties in which it is required only when the roofing manufacturer's written installation instructions require it". Morgan County is in the second group. If the shingle manufacturer's instructions for the assembly being installed call for an ice and water membrane, the code requires it on that job. DO NOT CARRY THIS ACROSS THE STATE, OR EVEN ACROSS THE COUNTY LINE. Several northern Indiana counties answer Yes on the same table. The City's own codified chapters say nothing either way: "ice barrier", "ice and water" and "ice shield" each occur zero times across Chapters 14, 18, 34 and 94.
Monroe County, Indiana - Building Department (Monroe County, Indiana)
NOT REQUIRED BY THE TABLE IN MONROE COUNTY - BUT THE MANUFACTURER CAN STILL REQUIRE IT, AND THAT IS THE HALF THAT CATCHES PEOPLE OUT. Indiana deletes the model climatic table and substitutes its own county-by-county table: 675 IAC 14-4.4-5 directs "Delete TABLE R301.2(1) and the corresponding footnotes and substitute to read as follows", and the substituted table runs one row per county. Row 53 is Monroe, and it carries "No" in the column headed "Ice Shield Underlayment Required". Twenty-seven of Indiana's ninety-two counties carry "Yes" there and they are the northern tier; Monroe is not one of them, so an answer carried down from a South Bend, Fort Wayne or Gary job would be wrong here. The rest of the Monroe County row reads wind speed 115 mph, seismic design category C, ground snow 20 psf, foundation depth 24 inches, winter design temperature 9 degrees F and weathering Severe - the seismic category C is worth noting, because it is the highest of the three Indiana uses and only a handful of southern counties carry it. The Indiana State Building Commissioner sets out the qualification in terms: Sections R903.1, R904.1 and R905.1 require roofing materials to be installed in accordance with the manufacturer's installation instructions, so "there are specific counties in which it is always required (per Table R301.2(1)), and specific counties in which it is required only when the roofing manufacturer's written installation instructions require it (per Sections R903 .1, R904.1 and R905 .1)." Monroe County is in that second group: the table does not compel an ice barrier, and the shingle manufacturer's printed instructions still can. The County may not add a requirement of its own, because IC 22-13-2-3(c) bars a local ordinance more stringent or detailed than the state rules.
Shelby County Building Inspector (Shelby County, Indiana)
NOT REQUIRED BY THE STATE TABLE FOR SHELBY COUNTY, BUT READ THE MANUFACTURER'S INSTRUCTIONS. The Shelby County row of Table R301.2(1) in the 2020 Indiana Residential Code, as substituted by 675 IAC 14-4.4-5, reads ice shield underlayment required No. WHAT THAT No MEANS, IN THE STATE'S OWN WORDS. The State Building Commissioner's memo explains that R903.1, R904.1 and R905.1 require roofing to be installed to the manufacturer's installation instructions, so there are counties where the barrier is always required and "specific counties in which it is required only when the roofing manufacturer's written installation instructions require it". Shelby County is in the second group. If the shingle manufacturer's instructions for the assembly being installed call for an ice and water membrane, the code requires it on that job. The County's own permit chart and Building Inspector FAQ say nothing on the point either way.
Town of Avon, Indiana - Building Department (Town of Avon, Indiana)
NOT REQUIRED BY THE TABLE IN HENDRICKS COUNTY, WHERE AVON SITS - AND THIS IS A COUNTY-BY-COUNTY ANSWER IN INDIANA, NOT A STATE ONE. Indiana deletes the model climatic table and substitutes its own: 675 IAC 14-4.4-5 directs "Delete TABLE R301.2(1) and the corresponding footnotes and substitute to read as follows", and the substituted table runs one row per county. Row 32 is Hendricks, and it carries "No" in the column headed "Ice Shield Underlayment Required". Twenty-seven of Indiana's ninety-two counties carry "Yes" there and they are the northern tier; the other sixty-five, Hendricks among them, carry "No". The rest of the Hendricks row reads wind speed 115 mph, seismic design category B, ground snow 20 psf, foundation depth 30 inches, winter design temperature 2 degrees, decay Slight to Moderate, termite Moderate to Heavy, weathering Severe and mean annual temperature 52.3 degrees. THE PART A ROOFER MUST NOT SKIP. A "No" in that column does not mean an ice barrier is never required on an Avon roof. The Indiana State Building Commissioner's Ice/Water Shield and Metal Drip Edge guidance of February 25, 2020 states that "there are specific counties in which it is always required (per Table R301.2(1)), and specific counties in which it is required only when the roofing manufacturer's written installation instructions require it". Hendricks County is in the second group. So on an ordinary Avon job the question is what the shingle manufacturer's printed installation instructions say - read them before deciding, because they, not the table, carry the answer here. Avon could not change this in either direction: IC 22-13-2-3(c) bars a more stringent or more detailed local requirement, and the Town publishes no roofing rule of its own.
Town of Brownsburg Development Services - Building and Inspections (Town of Brownsburg, Indiana)
NOT REQUIRED BY THE TABLE IN HENDRICKS COUNTY, WHERE BROWNSBURG SITS, AND THAT IS NOT THE WHOLE ANSWER. Indiana replaces the model climatic table with its own county-by-county table: 675 IAC 14-4.4-5 directs "Delete TABLE R301.2(1) and the corresponding footnotes and substitute to read as follows", and row 32, Hendricks, carries "No" in the column headed "Ice Shield Underlayment Required". THE PART A ROOFER MUST NOT SKIP. The Indiana State Building Commissioner's guidance of February 25, 2020 explains that the roofing chapter also requires installation to the manufacturer's instructions, so "there are specific counties in which it is always required (per Table R301.2(1)), and specific counties in which it is required only when the roofing manufacturer's written installation instructions require it". Hendricks County is in the second group. On an ordinary Brownsburg job, read the shingle manufacturer's printed installation instructions for the assembly being installed before treating the membrane as optional. The Town could not add a requirement of its own, because IC 22-13-2-3(c) bars a more stringent or more detailed local ordinance.
Town of Plainfield, Indiana - Development Services, Building Department (Town of Plainfield, Indiana)
NOT REQUIRED BY THE TABLE IN HENDRICKS COUNTY - BUT THE MANUFACTURER'S INSTRUCTIONS CAN STILL REQUIRE IT, AND THAT IS THE WHOLE POINT OF THIS ANSWER. Indiana deletes the model climatic table and substitutes its own: 675 IAC 14-4.4-5 directs "Delete TABLE R301.2(1) and the corresponding footnotes and substitute to read as follows", and the substituted table runs one row per county. Row 32 is Hendricks, and it carries "No" in the column headed "Ice Shield Underlayment Required". Twenty-seven of Indiana's ninety-two counties carry "Yes" there and they are the northern tier; Hendricks is one of the other sixty-five. The rest of the Hendricks row reads wind speed 115 mph, seismic design category B, ground snow 20 psf, foundation depth 30 inches, winter design temperature 2 degrees F and weathering Severe. WHAT "NO" ACTUALLY MEANS HERE, IN THE STATE BUILDING COMMISSIONER'S OWN WORDS. The requirement in Section R905.1.2 is triggered "as designated in Table R301.2(1)", and the Commissioner's Ice/Water Shield and Metal Drip Edge guidance of February 25, 2020 explains that the sections requiring installation in accordance with the manufacturer's instructions still apply on top of the table: "Together, these sections and Table R301.2(1) set forth the locations and circumstances in which ice/water shield are required. In short, there are specific counties in which it is always required (per Table R301.2(1)), and specific counties in which it is required only when the roofing manufacturer's written installation instructions require it (per Sections R903.1, R904.1 and R905.1)." Hendricks County is in the second group. So in Plainfield the ice barrier is not required by the table, and it IS required wherever the shingle you are installing calls for it in its own written installation instructions. Read the wrapper, not the map - and note that a manufacturer's warranty is a separate matter the Commissioner expressly declines to enforce.
Town of Zionsville Planning & Building Department (Town of Zionsville, Indiana)
NOT REQUIRED BY THE COUNTY TABLE HERE, BUT THE TOWN SAYS IN WRITING THAT IT ENFORCES THE MANUFACTURER'S INSTRUCTIONS, MEMBRANE INCLUDED. Indiana replaces the model climatic table with its own county-by-county Table R301.2(1), and the Boone County row reads Ice Shield Underlayment Required: No. The State Building Commissioner's memo explains what that No means: "there are specific counties in which it is always required (per Table R301.2(1)), and specific counties in which it is required only when the roofing manufacturer's written installation instructions require it (per Sections R903.1, R904.1 and R905.1)." Boone is in the second group. Zionsville's Roofing FAQ then says what the Town enforces. Asked whether it requires full adherence where a manufacturer instructs the membrane, "including installation of ice and water shield wherever the manufacturer instructs", the Town answers YES. Asked whether failing to install the roof per the manufacturer's instructions would be a code violation, it answers YES. And where the manufacturer does not call for it: "Zionsville makes no assertion as to ice and water shield (beyond what is required by the current Indiana Residential Code)." So read the printed installation instructions for the shingle actually being installed. If they call for the membrane, the Town treats leaving it out as a code violation.
Vigo County Building Inspections Department (Vigo County, Indiana)
NOT REQUIRED BY THE TABLE, AND THAT IS NOT THE WHOLE ANSWER. The Indiana Residential Code's Table R301.2(1) runs county by county, and the Vigo row reads wind speed 115, seismic design category B, ground snow load 20, frost depth 24, winter design temperature 9 degrees, decay slight to moderate, termite moderate to heavy, weathering severe, ice shield underlayment required No, air freezing index not more than 1500, mean annual temperature 53.1 degrees. WHAT THE STATE'S OWN MEMO SAYS THAT No MEANS. It means only that Vigo is not among the counties where the barrier is mandatory. R903.1, R904.1 and R905.1 still require roofing to be installed in accordance with the manufacturer's installation instructions, so where those instructions call for an ice-and-water membrane on the assembly being installed, that governs the job whatever the table says. Vigo County writes no ice-barrier provision of its own. CONTRAST WORTH CARRYING: Porter County reads Yes in that same column, so an Indiana roofer cannot move a practice between counties in either direction.
Warrick County Building Commission (Warrick County, Indiana)
NOT REQUIRED BY THE TABLE IN WARRICK COUNTY, AND THAT IS NOT THE END OF THE QUESTION. The Indiana Residential Code's Table R301.2(1), as amended by 675 IAC 14-4.4-5, runs county by county, and the Warrick row reads No in its ice shield underlayment column. WHAT THE STATE'S OWN MEMO SAYS THE No MEANS: "there are specific counties in which it is always required (per Table R301.2(1)), and specific counties in which it is required only when the roofing manufacturer's written installation instructions require it (per Sections R903.1, R904.1 and R905.1)." Warrick is in the second group. So where the shingle manufacturer's instructions call for an ice-and-water membrane on the assembly being installed, that requirement applies to the job regardless of the table. Warrick County's own building chapter was not opened for this record.
Ice barrier not required (explicit) — Kansas (17)
Butler County Community Development Department (Butler County, Kansas)
"Ice Barrier Underlayment Required: No" (Table R301.2(1), Climatic and Geographic Design Criteria, as amended by the Butler County Building Code, Article 6, Sec. 603(i), adopted by the Board of County Commissioners via Resolution 16-06, February 23, 2016).
City of Andover Building & Inspections Department (City of Andover, Kansas)
"Ice Barrier - None Required" (Table R301.2(1), Climatic and Geographic Design Criteria, Wichita-Sedgwick County Unified Building and Trade Code, "Wichita Jurisdiction" terms, which the City of Andover elected to opt into in full via Ordinance No. 1957, Sec. 4-301, adopted May 13, 2025).
City of Concordia - Building & Zoning (City of Concordia, Kansas)
The City's filled-in Table R301.2(1), inserted by Section 6-204 of its city code, enters "No" under "Ice barrier Underlayment required," so the IRC's ice barrier requirement at eaves does not apply in Concordia.
City of Derby - Building Trades & Inspections (City of Derby, Kansas)
Table R301.2(1) Climatic and Geographic Design Criteria, as amended by Ordinance No. 2623 (Section N, amending 2024 IRC Section R301.1), lists "Ice Barrier None Required." The ordinance's table footnote directs: "For footnotes, refer to Table R301.2(1) of the 2024 International Residential Code," i.e. Derby did not write a custom ice-damming footnote and instead adopts the base IRC's own "history of local damage" trigger language, filled in as not required for this table.
City of El Dorado - Building Department (City of El Dorado, Kansas)
The city's Adopted Codes sheet lists, among the design criteria its amendments to the 2006 International Residential Code establish, "Ice Barrier Underlayment Required: No."
City of Hays - Planning & Development Division (City of Hays, Kansas)
The Design Criteria published on the City Adopted Codes page read: "Ice Barrier Underlayment not required." The City's Roofing Permit application likewise states: "Ice Barrier is not required."
City of Haysville - Public Works Department (City of Haysville, Kansas)
"Ice Barrier - None Required" (Table R301.2(1), Climatic and Geographic Design Criteria, as amended within Section 4-301 of the Code of the City of Haysville, Kansas, adopting the International Residential Code, 2018 Edition).
City of Iola - Code Enforcement (City of Iola, Kansas)
Table 301.2(1) of the Residential Code, as inserted by Section 4-202.1 of the Code of the City of Iola, Kansas (adopting the 2012 International Residential Code), enters No in its ice barrier underlayment required column.
City of Lawrence Planning and Development Services, Building Safety Division (City of Lawrence, Kansas)
NOT REQUIRED BY LAWRENCE'S OWN ENACTED CLIMATIC TABLE, AND THE CITY'S GUIDANCE SAYS THE SAME. City Code Section 5-607 rewrites Table R301.2(1) of the 2018 IRC with the City's own values, and its "Ice Barrier Underlayment Required" column reads "No." The table's footnote ties that column to the roof-covering sections: "In accordance with sections R905.1.2, R905.4.3.1, R905.5.3.1, R905.6.3.1, R905.7.3.1 and R905.8.3.1, where there has been a history of local damage from the effects of ice damming, the jurisdiction shall fill in this part of the table with 'yes.' Otherwise, the jurisdiction shall fill in this part of the table with 'no.'" The City's 2023 Roof Permits guideline states: "Ice barrier underlayment are not required as amended in the city code." A manufacturer's installation instructions may still call for it.
City of Liberal - Building Department (City of Liberal, Kansas)
Section 6-303(h) of the Code of the City of Liberal amends Table R301.2(1) of the 2015 International Residential Code to read, among other entries, Ice barrier: "NO"; the filled-in table printed with it shows "No" under Ice Barrier Underlayment Required.
City of Russell - Building, Planning, and Zoning Department (City of Russell, Kansas)
Section 4-203(c) of the Code of the City of Russell inserts the city's entries into Table R301.2(1), Climatic and Geographic Design Criteria, of the 2018 International Residential Code; the ice barrier underlayment entry reads "Required -- No". The city's Model Codes page lists "Ice Barrier Underlayment - Not required" among its design criteria.
City of Topeka - Development Services Division (City of Topeka, Kansas)
IRC Table R301.2(1) as substituted by the City of Topeka lists "NO" in the "Ice Barrier Underlayment Required" column. Footnote h to the table states: "In accordance with Sections R905.2.7.1, R905.4.3.1, R905.5.3.1, R905.6.3.1, R905.7.3.1 and R905.8.3.1, where there has been a history of local damage from the effects of ice damming, the jurisdiction shall fill in this part of the table with 'YES.' Otherwise, the jurisdiction shall fill in this part of the table with 'NO.'" (Topeka Municipal Code 14.55.230, IRC Table R301.2(1), enacted by Ord. 20467 § 9, 12-5-23.)
City of Ulysses - Building & Code Compliance Department (City of Ulysses, Kansas)
Table R301.2(1) as amended by Section 4-203 of the Code of the City of Ulysses (adopting the International Residential Code, 2018 Edition) answers NO in the ice barrier underlayment required column. Under the table's own footnote h, the jurisdiction fills in "YES" only where there has been a history of local damage from the effects of ice damming.
City of Wichita - Metropolitan Area Building & Construction Department (MABCD) (City of Wichita, Kansas)
Table R301.2(1) Climatic and Geographic Design Criteria, as amended by Sec. 2.4.115 of the Wichita/Sedgwick County Unified Building & Trade Code (UBTC), Article 2, Section 4, lists "Ice Barrier - None Required." Footnote h to the amended table states the jurisdiction fills this cell in with "YES" only "where there has been a history of local damage from the effects of ice damming," and "Otherwise, the jurisdiction shall fill in this part of the table with 'NO.'"
Douglas County - Zoning and Codes (Building Codes) (Douglas County, Kansas)
Table R301.2(1), Climatic and Geographic Design Criteria, as completed and inserted by Section 13-203(c) of the Official County Code of Douglas County, Kansas (amending the 2018 International Residential Code), enters No in its ice barrier underlayment required column.
Sedgwick County - Metropolitan Area Building & Construction Department (MABCD) (Sedgwick County, Kansas (unincorporated))
Table R301.2(1) Climatic and Geographic Design Criteria, as amended by Sec. 2.4.115 of the Wichita/Sedgwick County Unified Building & Trade Code (UBTC), Article 2, Section 4, lists "Ice Barrier - None Required." Footnote h to the amended table states the jurisdiction fills this cell in with "YES" only "where there has been a history of local damage from the effects of ice damming," and "Otherwise, the jurisdiction shall fill in this part of the table with 'NO.'"
Shawnee County - Land Use & Development Department (Shawnee County, Kansas (unincorporated))
Shawnee County's own building-code page (https://www.snco.gov/ludev/building_code.php) states: "Shawnee County adopts by reference Title 14, Building and Construction of the City of Topeka Code as the Shawnee County Building Code. As currently in effect, this includes" Chapter 14.55 (International Residential Code) among the incorporated chapters; Chapter 14.55 is not among the seven chapters the county's resolution excludes. Under that incorporation, IRC Table R301.2(1) as substituted by the City of Topeka (TMC 14.55.230, Ord. 20467 § 9, 12-5-23) lists "NO" in the "Ice Barrier Underlayment Required" column, per footnote h ("where there has been a history of local damage from the effects of ice damming, the jurisdiction shall fill in this part of the table with 'YES.' Otherwise ... 'NO.'").
Ice barrier not required (explicit) — Missouri (8)
City of Columbia Building and Site Development Division (City of Columbia, Missouri)
NOT REQUIRED, PER THE CITY'S OWN INSERTED CLIMATIC TABLE, IN PLAIN WORDS. City Code Sec. 6-66 inserts the City's values into Table R301.2(1) of the adopted 2018 IRC, including "Ice Barrier Underlayment Required - No," alongside a ground snow load of 20 and a wind speed of 115 mph. That is a jurisdiction-specific answer written into the enacted code, not an inference from a regional default.
City of O'Fallon, Missouri - Building Division (City of O'Fallon, Missouri)
Table R301.2(1) Climatic and Geographic Design Criteria, as currently codified (Article X, 2021 IRC as amended by Ord. No. 7133, 9-12-2024): row "ICE BARRIER UNDERLAYMENT REQUIRED" = "No." This directly corroborates the city's separate 2017 re-roofing guide, which states: "Ice and Water Shield: Ice and water shield (R905.2.7) is not required per Table R301.2(1) as completed and adopted by the City." Confirmed from the current (2021 IRC) table itself, not just the older guide.
City of St. Louis, Missouri - Building Division (City of St. Louis, Missouri)
St. Louis's own amendment to Table R301.2(1) (Climatic and Geographic Design Criteria), codified in Chapter 25.11, Sec. 25.11.020 (Chapter 3 amendments), lists: "ICE SHIELD UNDERLAYMENT REQUIRED (j): Not Required" (alongside Ground Snow Load 20 psf, Winter Design Temp 5F, Air Freezing Index 963 F-days). This is an explicit, amended local table entry -- not silence or omission -- stating the ice-barrier underlayment provision of IRC R905.1.2 does not apply in the City of St. Louis. This is notably different from nearby Kansas City and Independence, MO, both of which amend the same table to REQUIRE ice barrier underlayment.
City of St. Peters, Missouri - Building Department (City of St. Peters, Missouri)
"For asphalt shingle roofs, the ice barrier mentioned in IRC Section R905.2.7 Ice Barrier, is not required by IRC Table R301.2 as amended and adopted by the City of St. Peters." (City of St. Peters "Residential Re-Roofing Requirements," Building Department, "Revised 3/27/2024.") Directly corroborated by the currently codified Section 504.040(A)(25), which amends Table R301.2 and lists: "Ice barrier underlayment on the roof = none."
City of Wentzville, Missouri - Building Division (City of Wentzville, Missouri)
Sec. 500.080(9), amending Table R301.2(1) Climatic and Geographic Design Criteria (currently codified, 2021 IRC as amended, most recently amended 1-24-2024): row "Ice Barrier Underlayment Required" = "NO." Sourced directly from the city's own currently codified table, not from a separate guidance document.
St. Charles County, Missouri - Division of Building and Code Enforcement (St. Charles County, Missouri)
Table R301.2 (Climatic and Geographic Design Criteria) as filled in by the county's residential code amendment lists "Ice Barrier Underlayment Required" as "NO" for St. Charles County.
St. Louis County - Department of Transportation and Public Works (Building Division) (St. Louis County, Missouri)
St. Louis County's own amended climatic design table states the requirement is NOT triggered. The county's Chapter 1115 amendment to IRC Table R301.2(1) "Climatic and Geographic Design Criteria" lists, under the "ICE BARRIER UNDERLAYMENT REQUIRED" column, the value "NO" for St. Louis County (footnote h cross-references Sections R905.1.2, R905.4.3.1, R905.5.3.1, R905.6.3.1, R905.7.3.1 and R905.8.3.1, and states the jurisdiction fills this cell in as YES/NO "where there has been a history of local damage from the effects of ice damming"). This is corroborated word-for-word by three separate county publications: the Single-Family Dwelling Design Checklist ("Ice Barrier underlayment is not required (R905.1.2; SLCO Revised Ordinance Table R301.2(1))"), the Residential Room Additions guide ("Ice Barriers are not required by St. Louis County (R905.1.2; SLCO Revised Ordinance Table R301.2(1))"), and the amended-code ordinance document itself (the Table R301.2(1) entry). The county states this affirmatively; it is not simply an unanswered question.
St. Louis County, Missouri Department of Transportation and Public Works - Building Permit Section (permitting authority for the City of Chesterfield, Missouri, by contract) (City of Chesterfield, Missouri)
Chesterfield's own Municipal Code, Chapter 500, Table R301.2(1) Climatic and Geographic Design Criteria (as filled in/amended by the city's own ordinance, Attachment B "1116.103 - Amendments to the International Residential Code... Chapter 3 Building Planning"), lists "Ice Barrier Underlayment Required" as "NO" for Chesterfield. Independently corroborated by St. Louis County's own Re-Roofing Checklist for contracting municipalities: "Ice Barrier underlayment is not required (R905.1.2; SLCO Revised Ordinance Table R301.2(1))." Two independent official sources agree Chesterfield does NOT require ice barrier/ice-and-water-shield underlayment as a blanket rule (footnote h ties this to local history of ice-damming damage, which Chesterfield and St. Louis County have both filled in as "NO").
Ice barrier not required (explicit) — Nebraska (2)
City of Alliance - Community Development (Building and Zoning) (City of Alliance, Nebraska)
Not required in Alliance, and the City says so in its own amended code rather than by silence. Municipal Code Section 105-22 amends Table R301.2(1) of the 2018 International Residential Code and enters a footnote marker in the ICE BARRIER UNDERLAYMENT REQUIRED column instead of a Yes or No. The footnote reads: "Ice barrier is recommended but not required. Any installation of ice barrier shall be installed according to Section R905.1.2." So an Alliance re-roof may be built without an ice barrier, and where one is installed it must still be installed to the code's own standard. This is a local answer, not a regional one - other Nebraska cities in this directory answer Yes in the same column, and a neighbouring jurisdiction's requirement says nothing about Alliance. Note also that a manufacturer's installation instructions or a warranty may call for an ice barrier even where the City does not.
City of Holdrege - Municipal Services Department, Building Inspection Division (City of Holdrege, Nebraska)
Holdrege's own rewrite of Table R301.2(1) at City Code § 9-601(B) states "Ice Shield Underlayment (No)" -- a local amendment to the base 2018 IRC table, quoted verbatim, read directly rather than inferred from the base code. No other section of § 9-601 through § 9-604 mentions an ice barrier or ice shield requirement.
Ice barrier not required (explicit) — New Mexico (2)
City of Albuquerque, New Mexico - Building Safety Division (Planning Department) (City of Albuquerque, New Mexico)
Earned from Albuquerque's own printed design table, not inferred from climate or region. The state rule hands this row to the AHJ - 14.7.3.11(A)(1) NMAC amends footnote f of IRC Table R301.2 to read "The authority having jurisdiction shall fill in this part of the table with the seismic design category determined from Section R301.2.2.1 or information from the U.S.G.S. software Design Values for Buildings found online." Albuquerque filled it in. The Uniform Administrative Code of the City of Albuquerque (2024 Edition), Chapter 3 addition to R301.2, prints "Table R301.2 Climatic and Geographic Design Criteria" with a column headed "Ice Shield Under-Layment Required" and enters "N/A" in it. No ice-barrier underlayment is designated as required for Albuquerque by the City's own table, and neither the Uniform Administrative Code nor 14.7.3 NMAC imposes one elsewhere. The 2024 Uniform Administrative Code was read in full and contains no ice-barrier or ice-shield provision beyond that table cell.
City of Las Cruces, New Mexico - Community Development Department (Building Section) (City of Las Cruces, New Mexico)
Earned from the City's own enacted design table. The state rule hands this row to the AHJ - 14.7.3.11(A)(1) NMAC amends footnote f of IRC Table R301.2 so that "The authority having jurisdiction shall fill in this part of the table" - and Las Cruces filled it in by ordinance: the Table R301.2(1) printed at Section 30-722(B)(10) of the Las Cruces Municipal Code enters "No" in the "Ice Barrier Underlayment" column. That is an explicit negative in the City's own completed table, not an inference from climate. Neither Chapter 30's building-standards division (Sections 30-721 and 30-722, the City's complete code-adoption and amendment instrument) nor 14.7.3 NMAC imposes an ice-barrier requirement elsewhere.
Ice barrier not required (explicit) — South Carolina (8)
City of Charleston - Building Inspections Division (City of Charleston, South Carolina)
The City of Charleston's own Climatic and Geographic Design Criteria table for the 2021 South Carolina Building Codes prints "No" in its ice barrier underlayment required column, with a mean annual temperature of 66.1 degrees F and an air freezing index under 1500.
City of Florence - Building & Permitting Department (City of Florence, South Carolina)
The City's amended Table 301.2(1), Climatic and Geographic Design Criteria (City Code Section 4-805, Ord. No. 2017-06), reads "Ice Barrier Underlayment Required - No."
City of Greenville - Building Codes and Permit Center (City of Greenville, South Carolina)
The City's amended Table 301.2(1), Climatic and Geographic Design Criteria (City Code Section 6-806, as amended by Ord. No. 2022-81), reads "Ice Barrier Underlayment Required - No."
Greenville County - Building Safety and Code Enforcement (Greenville County, South Carolina (unincorporated))
Greenville County's own Table R301.2(1), adopted in the County's 2021 residential code ordinance, reads "Ice Barrier Underlayment Required No" (with a winter design temperature of 22 degrees F). The South Carolina modifications to the 2021 International Residential Code make no change to the ice barrier provisions.
Orangeburg County - Permitting and Inspections Department (Orangeburg County, South Carolina (unincorporated))
Orangeburg County's own climatic and geographic design criteria table, Attachment 1 to Ordinance No. 2025-09-15-25 (Table R301.2), enters "NO" in its column for ice barrier underlayment required. The table was enacted with the County's 2024 code adoption, effective January 1, 2026. Neither edition's South Carolina modifications add an ice barrier requirement.
Town of Irmo - Building Permits and Inspections (Code Consulting & Inspection Services, LLC) (Town of Irmo, South Carolina)
Table R301.2(1), Climatic and Geographic Design Criteria, as printed in Town of Irmo Code Section 8-32 (Ord. No. 23-21, 9-19-2023), lists "Ice barrier underlayment required: No" for the Town.
Town of Moncks Corner - Building Department (TOMC Inspections) (Town of Moncks Corner, South Carolina)
The Town's climatic and geographic design criteria for Table R301.2(1), adopted in Town Code Section 8-163, state: "Ice barrier underlayment required: No."
Union County - Department of Building Safety (Union County, South Carolina (unincorporated))
Table R301.2(1), Climatic and Geographic Design Criteria, as printed in Union County Code Section 7-6(h) (Ord. No. 298, 10-26-15), lists "Ice Barrier Underlayment Required" as "No" for the County.
Ice barrier not required (explicit) — Tennessee (9)
City of Clarksville Building & Codes Department (City of Clarksville, Tennessee)
Table R301.2(1), Climatic and Geographic Design Criteria, as replaced by the City of Clarksville's residential-code amendments (Code of Ordinances Sec. 4-801, current through Ord. No. 40-2020-21), lists "Ice Barrier Underlayment Required" as "No" for the city. No separate ice-barrier provision appears elsewhere in the city's local amendments.
City of Johnson City Building Division (City of Johnson City, Tennessee)
The City of Johnson City's own published Design Criteria sheet, distributed by the Building Division through its Contractor Requirements and Information document center for designers, lists "Ice Barrier Underlayment Required = No" alongside the city's other Table-R301.2(1)-type design values (ground snow load, seismic design category, wind speed, frost line depth, weathering, termite risk). No other provision in the city's adopted 2018 IRC amendments (Code of Ordinances section 12-301(2), read in full) addresses ice barrier underlayment.
City of Knoxville Plans Review and Inspections (City of Knoxville, Tennessee)
Table R301.2(1) of the City of Knoxville's Residential Building Code amendments (Code of Ordinances Sec. 6-42, current through Ordinance No. O-125-2024, the same ordinance that adopted the 2024 IRC) lists "Ice Barrier Underlayment Required" as "No" for the city. No separate ice-barrier provision appears elsewhere in the city's local amendments.
City of Murfreesboro Building and Codes Department (City of Murfreesboro, Tennessee)
Ordinance 18-O-71, Section 4(N), amends Table R301.2(1), Climatic and Geographic Design Criteria, by inserting the city's specific values into the table, including the row "Ice Barrier Underlayment Required" set to "No." No separate ice-barrier provision appears elsewhere among the ordinance's local amendments.
Knox County, Tennessee - Codes Administration (Knox County, Tennessee)
The county's own 2018 IRC amendments document, read in full, amends Table R301.2(1) (Climatic and Geographic Design Criteria) with the instruction "Insert 'No' in the table for Ice Barrier Underlayment Required." No other provision in either amendment document adds an ice-barrier or ice-and-water-shield requirement.
Memphis and Shelby County Office of Construction Code Enforcement (Division of Planning and Development) (City of Memphis, Shelby County, Tennessee)
The office's Policy for Roof Installations answers in Q&A form: "Does Shelby County require an ice and water shield (barrier)? No, per our local amendment." Confirmed again: "there are no amendments to chapter 9 of this code other than we do not require an ice barrier per section 905.1.2." This is a LOCAL AMENDMENT removing the 2021 IRC's default ice-barrier requirement -- consistent with Memphis's climate (ice-dam formation is not a design concern there).
Metropolitan Government of Nashville & Davidson County, Tennessee - Department of Codes and Building Safety (Codes Administration) (Metropolitan Government of Nashville and Davidson County, Tennessee)
Table R301.2 of Metro Ordinance BL2025-898 (Metropolitan Code of Laws Title 16, ch. 16.08, Sec. 16.08.014, item F, Amendments to the 2024 International Residential Code) lists "Ice Barrier Underlayment Required" as "No" for Nashville and Davidson County. No separate ice barrier provision appears elsewhere in Metro's local IRC amendments (Sec. 16.08.014, items A through P, read in full).
Shelby County, Tennessee - Division of Planning and Development, Construction Code Enforcement (Shelby County, Tennessee)
Shelby County's own "Policy for Roof Installations" FAQ states: "Does Shelby County require an ice and water shield (barrier)? No, per our local amendment," citing IRC Section 905.1.2. The same document states this is the only provision of IRC Chapter 9 the county has amended. The county's own Table R301.2 (Climatic and Geographic Design Criteria), as amended by Joint Ordinance No. 525, lists "Ice Barrier Underlayment Required" as "No."
Town of Smyrna, Tennessee - Building Safety Department (Town of Smyrna, Rutherford County, Tennessee)
Not required. The Town of Smyrna's Climatic and Geographic Design Criteria sheet lists "Ice Barrier No", and the same entry appears in its line-by-line modifications as part of the amendment to Table R301.2. That entry is the operative act rather than a description of the weather: the adopted residential code conditions its ice barrier requirements on a history of local damage from ice damming as designated in Table R301.2, and Smyrna has made the designation in the negative. A roofer is free to install an ice and water barrier as good practice or because a shingle manufacturer's warranty calls for it, but the Town does not require one.
Ice barrier not required (explicit) — Texas (22)
City of Abilene - Building Inspections Division (City of Abilene, Texas)
Table R301.2(1), Climatic and Geographic Design Criteria, as filled in by the City of Abilene's 2021 IRC amendments, enters "No" in the ice barrier underlayment column for Abilene.
City of Arlington - Planning & Development Services Department (City of Arlington, Texas)
Ice barrier underlayment is not required in Arlington: the city's own amendments to the 2021 IRC do not require it, and the city cites the region's lack of a history of ice damming. Residential roof decking, drip edge, and ventilation requirements are enforced per the 2021 IRC. (City of Arlington Re-Roof Permits & Inspections technical bulletin.)
City of Carrollton - Building Inspection (City of Carrollton, Texas)
Table R301.2(1), Climatic and Geographic Design Criteria, as amended by the city's 2024 I-Codes amendments (Ordinances 4265, adopted 7-8-2025, and 4290, adopted 12-2-2025, codified at ecode360 Ch. 150 Sec. 150.016), lists "ICE BARRIER UNDERLAYMENT: No" for Carrollton (Ground Snow Load 8 lb/ft2, Winter Design Temp 22F, Air Freezing Index 150). Architect-verified directly from the codified amendment attachment, 2026-07-18.
City of Corpus Christi - Development Services Department (City of Corpus Christi, Texas)
Table R301.2(1), Climatic and Geographic Design Criteria, as amended in Sec. 14-291 of the City Code (2021 IRC), lists "Ice Barrier Underlayment Required" as "N/A" for Corpus Christi, and Sec. 14-291 amends no Chapter 9 provision.
City of El Paso - Planning & Inspections Department (City of El Paso, Texas)
El Paso's completed Table R301.2(1), Climatic and Geographic Design Criteria (City Code Sec. 18.10.050, Ord. No. 019528, 8-1-2023), lists "Ice Barrier Underlayment Required" as "No" for the City of El Paso.
City of Fort Worth - Development Services Department (City of Fort Worth, Texas)
Table R301.2(1), Climatic and Geographic Design Criteria, as amended by the City's adopted IRC amendments, lists "Ice Barrier Underlayment Required" as "No" for Fort Worth (2021 IRC amendments, Ord. No. 25383-03-2022, Sec. 7-62, passed 3-8-2022, eff. 4-1-2022).
City of Georgetown - Building Permits and Inspections (City of Georgetown, Texas)
The city's Roofing permits page answers "Are ice barriers required?" with "No." The city's residential amendments to the 2021 International Residential Code (Code of Ordinances Secs. 15.03.020 through 15.03.150) do not amend Chapter 9 and do not print a climatic design table. On valleys, the same page states: "Valley linings shall be installed in accordance with the manufactures instructions" (Section R905.2.5.2 as the city cites it) and that all roof installations must follow the manufacturer's instructions and the 2021 IRC.
City of Grapevine - Building Inspection Department (City of Grapevine, Texas)
Table R301.2 (Climatic and Geographic Design Criteria) as adopted in the city's Residential Code amendments lists "ICE BARRIER: No" for Grapevine (City of Grapevine, Chapter 7 Buildings and Construction, Article V Residential Code, Sec. 7-140/7-142).
City of Houston - Houston Public Works, Building Code Enforcement (Houston Permitting Center) (City of Houston, Texas)
Houston's own Table R301.2(1), Climatic and Geographic Design Criteria, in the Houston Amendments to the 2021 IRC (Ordinance No. 2023-907), lists ice barrier underlayment required as NO for the City (same row: ground snow load 0, winter design temperature 28, air freezing index under 1500, mean annual temperature 68.2).
City of Lewisville - Building Services Division (City of Lewisville, Texas)
City of Lewisville's amendments to the 2021 International Residential Code (Code of Ordinances Sec. 4-32) fill in Table R301.2(1), Climatic and Geographic Design Criteria, for the city: the "ICE BARRIER UNDERLAYMENT REQUIRED" column is set to "No" (row also reads ground snow load 5 lb/ft, wind speed 115 mph 3-sec gust / 76 mph fastest mile, seismic design category A, winter design temp 22 deg F, flood hazards "Local Code", air freezing index 150, mean annual temp 64.9 deg F).
City of Lubbock - Building Safety Department (City of Lubbock, Texas)
Table R301.2 as replaced by City Code Section 28.14.004(b) (Ordinance No. 2024-O0029, adopting the 2021 International Residential Code) lists "Ice Barrier Underlayment Required" as "No" for Lubbock.
City of Midland - Development Services, Permitting and Inspections (City of Midland, Texas)
Table R301.2(1), Climatic and Geographic Design Criteria, as rewritten by Midland's IRC amendments (City Code Sec. 4-11-3), lists "Ice Barrier Underlayment Required" as "No" for the City of Midland.
City of Missouri City Development Services Department (City of Missouri City, Texas)
NOT REQUIRED, IN THE CITY'S OWN INSERTED CLIMATIC TABLE. Sec. 14-352(13) amends Table R301.2 "by inserting the following design criteria in the table," including "Ice Barrier Underlayment Required: No," alongside a ground snow load of 0 and an air freezing index of 50. That is a first-party answer written into the City's adopted residential code.
City of New Braunfels - Building Safety Division (City of New Braunfels, Texas)
Table R301.2(1), Climatic and Geographic Design Criteria, as filled in by the City's 2021 IRC amendments (Code of Ordinances Sec. 14-29(d)), lists "Ice Barrier Underlayment Required" as "No" for New Braunfels.
City of North Richland Hills - Building Inspection Department (City of North Richland Hills, Texas)
Table R301.2(1), Climatic and Geographic Design Criteria, as amended by the City's adopted IRC amendments, lists "Ice Barrier Underlayment Required" as "No" for North Richland Hills (2024 IRC amendments, Ordinance No. 3947, Sec. 98-142, adopted 2/9/2026).
City of Odessa - Building Inspection Division (City of Odessa, Texas)
Table R301.2(1), Climatic and Geographic Design Criteria, as amended by the City of Odessa (City Code Sec. 3-5-2, amendments to the 2018 IRC), lists "ICE BARRIER UNDERLAYMENT REQUIRED: NO" for Odessa.
City of Rowlett - Building Safety Department (City of Rowlett, Texas)
Table R301.2(1) "Climatic and Geographic Design Criteria," as amended by Exhibit A (International Residential Code Amendments, 2021 Ed.) to the City of Rowlett's adopted-code ordinance, lists "No" in the Ice Barrier Under-Layment column (alongside Winter Design Temp 22°F, Air Freezing Index 150, Ground Snow Load 5 lb/ft).
City of San Angelo Building Permits & Inspections (City of San Angelo, Texas)
NOT REQUIRED, IN THE CITY'S OWN AMENDED CLIMATIC TABLE. City Code Sec. 4.04.092 amends Table 301.2(1) of the 2021 International Residential Code to read, among its rows, "Ice Barrier Underlayment Required: No," alongside a ground snow load of five psf and a winter design temperature of 32 degrees F.
City of San Antonio Development Services Department (DSD) (City of San Antonio, Texas)
San Antonio's own Table R301.2 (as amended by Sec. 10-37 of City Code Chapter 10, 2024 IRC local amendments, Ordinance No. 2025-01-30-0075) lists "ICE BARRIER UNDERLAYMENT REQUIRED" as "NO" for the city (same table row also shows Winter Design Temp 30 degrees F, Air Freezing Index 16, Mean Annual Temp 68.7 degrees F -- consistent with a no-ice-barrier climate).
Denton County - Development Services (Denton County, Texas)
Denton County has adopted no building code that reaches reroofing an existing single-family home. Its Fire Code, the 2021 International Fire and Building Code, carves those homes out of its own scope at Section 101.2, Exception 1, which provides that one- and two-family dwellings and townhomes of not more than two attached units "shall comply with Local Government Code 233 Subchapter F 'Residential Building Code'" instead. Subchapter F in turn reaches only new residential construction, which Texas Local Government Code Section 233.151 defines as a single-family house or duplex built on a vacant lot, or an addition increasing an existing home's square footage or value by more than 50 percent. Ordinary roof repair and replacement is neither. The county imposes no ice barrier or ice-and-water-shield requirement on that work. Note that under Texas Local Government Code Section 233.153(c) a municipality's own building code controls inside that municipality's extraterritorial jurisdiction, so a home in an ETJ may be governed by a city's code rather than by the county.
Town of Flower Mound - Building Inspections Department (Town of Flower Mound, Texas)
Table R301.2(1) "Climatic and Geographic Design Criteria," as amended by Exhibit F (Local Amendments to the 2024 International Residential Code) to the Town of Flower Mound's adopted-code ordinance, lists "No" in the Ice Barrier Under-Layment column (alongside Winter Design Temp 22°F, Air Freezing Index 150, Ground Snow Load 9 lb/ft).
Travis County Development Services (Transportation and Natural Resources) (Travis County, Texas)
Travis County has adopted no building code that reaches reroofing an existing single-family home. Travis County Code Chapter 480, Residential Construction Standards, applies by its Section 480.003 only to "new residential construction," which Section 480.002 defines as "Residential construction of a single-family house or duplex on a vacant lot" or "Construction of an addition to an existing single-family house or duplex, if the addition will increase the square footage or value of the existing residential building by more than 50 percent." Ordinary roof repair and replacement is neither. The county's Fire Code, Chapter 201, is capped by the same statutory scope and does not reach these dwellings either. The county imposes no ice barrier or ice-and-water-shield requirement on that work. Note that under Texas Local Government Code Section 233.153(c) a municipality's own building code controls inside that municipality's extraterritorial jurisdiction, so a home in an ETJ may be governed by a city's code rather than by the county.
Ice barrier not required (explicit) — Virginia (14)
Botetourt County - Development Services Division (Botetourt County, Virginia)
Botetourt County's Climatic Design Criteria sheet (updated December 2025) answers "No" under "Ice Barrier Underlayment Required". No ice barrier is required by the County's design criteria; a manufacturer's installation instructions may still call for one.
City of Chesapeake - Department of Development and Permits (City of Chesapeake, Virginia)
Chesapeake's own Table R301.2, Climatic and Geographic Design Criteria, for the 2021 Virginia Residential Code lists "ICE BARRIER UNDERLAYMENT REQUIRED" as "None Required" for the City.
City of Hampton - Community Development Department, Development Services Center (City of Hampton, Virginia)
The City's Residential Design Criteria sheet prints "No" for "Ice barrier underlayment required". Virginia's amendments to the IRC in the 2021 Virginia Residential Code (VCC Section 310.8) contain no ice-barrier provision, and City Code Chapter 9 contains none. Manufacturer instructions may still call for it.
City of Harrisonburg - Building Inspections Division (City of Harrisonburg, Virginia)
Harrisonburg's own design criteria table, City Code Sec. 11-1-1(c) ("Climatic and Geographic Design Criteria" for the City of Harrisonburg, section last amended by an Ordinance of January 11, 2022), answers "No" under "Ice Barrier Underlayment Required". The Building Inspections Division's current design-criteria statement does not address an ice barrier. Virginia's amendments to the IRC that make up the 2021 Virginia Residential Code contain no ice-barrier provision, and City Code Title 11 contains none. Manufacturer instructions may still call for it.
City of Newport News - Department of Codes Compliance (City of Newport News, Virginia)
Both of the City's design-criteria statements answer no: the Codes Compliance Design Criteria page prints "Ice barrier underlayment required No", and City Code Sec. 13-24(a), which fills in Table R301.2(1), prints "No" under "Ice Shield Underlayment Required". Virginia's amendments to the IRC in the 2021 Virginia Residential Code (VCC Section 310.8) contain no ice-barrier provision, and City Code Chapter 13 contains none. Manufacturer instructions may still call for it.
City of Roanoke - Permit Center (Planning, Building and Development) (City of Roanoke, Virginia)
The City's own Local Climatic Design Criteria sheet (updated February 2025), in its "Residential 1 & 2 Family Dwelling Construction Design Parameters" table, answers "No" under "ICE BARRIER UNDERLAYMENT REQUIRED" on the Roanoke City row, and gives the same answer for Roanoke County, Vinton and Salem. Virginia's amendments to the International Residential Code (Virginia Construction Code Section 310.8) contain no ice barrier amendment.
City of Salem - Community Development, Building Inspections (City of Salem, Virginia)
The City's Climatic Design Criteria sheet ("Local Design Criteria for Roanoke City, Salem City, Roanoke County and Town of Vinton", form revised January 2015) answers "No" in the "Ice Shield Req?" column of its IRC Table R301.2(1) entries on the Salem row. That sheet lists the 2018 model codes under a statewide code "Effective 7/1/2022", an edition earlier than the 2021 code the City now enforces; the newer regional sheet published by Roanoke County (form revised February 2025, "in accordance with the 2021 editions") also answers "No" for Salem. No ice barrier is required by either table; a manufacturer's installation instructions may still call for one.
City of Virginia Beach - Permits & Inspections Division (City of Virginia Beach, Virginia)
The City's Table R301.2(1), Climatic and Geographic Design Criteria, prints "NR" in its "Ice Shield Underlayment" column; the table does not spell out the abbreviation. Virginia's amendments to the IRC in the 2021 Virginia Residential Code (VCC Section 310.8) contain no ice-barrier provision, and City Code Chapter 8 contains none. Manufacturer instructions may still call for it.
Franklin County - Building Inspections Office (Franklin County, Virginia)
Franklin County's Local Design Criteria sheet ("Local Design Criteria for Franklin County"), which gives the County's entries for the Virginia Residential Code climatic design table (Table R301.2(1)), answers "No" in the "Ice Shield Req?" column on the Franklin County row. The sheet (form revised June 14, 2023) says it is "in accordance with the 2018 editions of the Virginia USBC"; it is the County's current published design criteria sheet, linked from its Forms for Building page. No ice barrier is required by the County's table; a manufacturer's installation instructions may still call for one.
Greene County - Building Inspections Department (Greene County, Virginia)
Greene County’s Building Design Criteria sheet answers the ice barrier question in one line: "Ice and Water Shield is not required." The sheet is headed "Building Design Criteria for County of Greene", is dated "Updated: May 31, 2023", and is posted on the County’s website; it lists the 2018 Virginia Uniform State Building Codes, an older edition than the 2021 code the County now says it enforces, and it is not listed among the Helpful Documents on the County’s Building Inspections page. A manufacturer’s installation instructions may still call for an ice barrier.
Pittsylvania County - Community Development, Building Inspections (Pittsylvania County, Virginia)
Pittsylvania County's Building Codes page lists "Ice Shield Required: NO" in the County's design criteria. That is the County's entry for the ice barrier line of the Virginia Residential Code's climatic design criteria table, which Virginia leaves to each locality to complete. A manufacturer's installation instructions may still call for it.
Powhatan County - Building Inspections Department (Powhatan County, Virginia)
Powhatan County's Building Codes page lists "Ice Barrier underlayment: No" among its design information for the county. No ice barrier is required by the County's design criteria; a manufacturer's installation instructions may still call for one.
Roanoke County - Office of Building Safety (Roanoke County, Virginia)
The County's Local Design Criteria sheet, which gives the Virginia Residential Code Table R301.2(1) entries for Roanoke City, Salem City, Roanoke County and the Town of Vinton, answers "No" in the "Ice Shield Req?" column on the Roanoke County row (form revised February 2025). No ice barrier is required by the County's table; a manufacturer's installation instructions may still call for one.
Rockingham County - Building Services (Rockingham County, Virginia)
Rockingham County's own Climate and Geographic Design Criteria table (dated 2023) answers "Ice Shield Underlayment Required" with "No". Its footnote says the entry is "YES" for areas where the average daily temperature in January is 25 degrees Fahrenheit or less, or where there has been a history of local damage from ice damming, and "NO" otherwise. The table is filed in the County's online document center under a 2023 name, before the 2021 Virginia code's January 18, 2024 effective date. A shingle manufacturer's installation instructions still apply to the job.
