Adopted code

Town of Blue River - Building Department

Yes, a permit is required to replace a roof in Blue River, CO, issued by Town of Blue River - Building Department. The Town's Building Department page states permits are grouped into three types. "Type C Permits Include: Staining/Siding Roofs Windows Interior Remodel Forest Management (Tree Cutting) Hot Tubs Plumbing, Electrical, Mechanical Permits. Type C Permits may be approved by Town Staff," which places roof work in the permit-required category (roofing is not listed among any permit-exempt items on the page), so a roofing permit is required. The Building Official is reached via the Charles Abbott Associates address "[email protected]." Type A Permits (new construction, additions, garages, variances, plat amendments, subdivisions) require Planning & Zoning Commission approval, which "meets once a month on the first Tuesday of the month at 6:00 p.m." Type B Permits (sheds/small structures, excavation, landscaping, berms, solar, fences, chicken enclosures, decks) "do not require Planning & Zoning Commission Approval and may be approved by the Building Official." No explicit Town contractor-license or registration requirement was found; the Town's separate Licensing page (townofblueriver.colorado.gov/licensing) covers a general $50/year Town of Blue River Business License for "[a]nyone conducting business within the Town" and a Short-Term Rental license, neither of which is stated as a contractor-specific registration.

Adopted code
Ordinance No. 2026-01 (signed 2026-03-07, effective March 31, 2026; read from the Town's own signed ordinance PDF) adopts by reference the 2024 editions of the International Building Code, International Residential Code, International Mechanical Code, International Property Maintenance Code, International Existing Building Code, International Energy Conservation Code, International Swimming Pool and Spa Code, and International Wildland-Urban Interface Code, plus the 2023 National Electrical Code, the Colorado Fuel Gas Code, the Colorado Plumbing Code, the Colorado Wildfire Resiliency Code, and the Colorado Model Electric Ready and Solar Ready Code, together with the regulations of the Summit County Public Health Department and the Upper Blue Sanitation District. The ordinance repeals and reenacts Municipal Code Chapter 18 Article II (which previously codified the 2018 IBC via Ordinance No. 2023-05).
Drip edge
Required — Not separately amended by the Town of Blue River. Ordinance No. 2026-01, Sec. 18-2-40 (Residential Code amendments), was read in full -- a textually exhaustive, numbered list of items (1) through (39) covering IRC Section R101.1 through Part VIII (Electrical) -- and does not delete or modify Section R905.2.8.5, so the base 2024 IRC drip-edge requirement stands as adopted code. Sec. 18-2-20 (Adoption of Codes) states the codes "are hereby adopted by reference... subject to the amendments set forth in this Chapter 18," and Sec. 18-2-10(b) states "No building or work on any building shall be commenced within the Town without first obtaining a building permit as required by this Article and the codes adopted in this Article." About drip edge
Ice & water shield
Required — 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." About ice & water barrier
Impact-resistant roofing
Not required — Blue River Ordinance No. 2026-01, Sec. 18-2-40 (Residential Code amendments), was read in full -- a textually exhaustive, numbered list of items (1) through (39) -- and contains no UL 2218, Class 4, or impact-resistance provision anywhere. Sec. 18-2-40 item (20) does amend IRC R902.1 Roof Assemblies to require Class A fire-rated roof coverings ("tested in accordance with ASTM E108 or UL 790"), which is a fire classification, not an impact-resistance (hail) rating.
Wind design criteria
Blue River Ordinance No. 2026-01 (signed 2026-03-07), Sec. 18-2-40 (Residential Code amendments) item (12), amends and prints Table R301.2(1) Climatic and Geographic Design Criteria: Ground Snow Load "140 (100 ROOF)" lbs/sq ft; Wind Design Speed "ASCE 7-22*"; Topographic effects "YES"; Special wind region "Yes"; Wind-borne debris zone "NO"; Seismic Design Category "B"; Weathering "SEVERE"; Frost line depth "42 inches"; Termite "SLIGHT TO MODERATE"; Winter Design Temp "-10 F"; Ice Barrier Underlayment Required "YES"; Flood Hazards "SEE MAPS"; Air Freezing Index "2500"; Mean Annual Temp "32 F." The table carries the footnote: "*Hurricane prone region provisions are not required."
Sales & use tax
8.875% combined (state 2.9% + Summit County base 2.0% + Summit County Mass Transit System tax 0.75% + Summit Combined Housing Authority (MHA) tax 0.725% + Town of Blue River 2.5%; the county's 2% short-term-lodging tax does not apply to ordinary contractor/retail sales). Blue River is a statutory municipality; Colorado Department of Revenue form DR 1002 (a 2019/2020-vintage publication) lists Blue River as state-collected, printing the Town's own city rate as "Blue River / Summit / 2.5% / 2% [use tax]," Summit County's rate as "2.75%1" (footnote: "Rate includes...0.75% [Mass Transit System tax] in Summit County"), and a separate Multi-Jurisdictional Housing Authority entry, "Summit Combined Housing Authority," of "0.725%" applying countywide. Summit County's own Finance Department "Sales Tax Rates" table (linked live from the County's official Sales Tax page) corroborates this exactly, itemizing Blue River's "Base Sales Tax Rate" as 8.875%: "State of Colorado 2.900%," "Summit County 2.000%," "City 2.500%," "Mass Transit 0.750%," "Affordable Housing 0.725%." Re-verified 2026-08-27 against the January 2026 edition of Colorado Department of Revenue form DR 1002, read from a rendered image of its tables rather than from extracted text: the state, county and city figures above match that edition exactly. Where the text above names the June 19, 2019 revision of DR 1002, that describes the edition the figure was originally taken from and is not a current citation.
