Do you need a permit to replace a roof in Overland Park, KS?

Adopted code

City of Overland Park - Building Safety Division

No — Overland Park, KS does not require a permit for like-for-like roof replacement (City of Overland Park - Building Safety Division). The city's Residential Building Permit Exceptions and Guidance page (referencing Municipal Code 16.100.105.2) states under "Roofing and Re-Roofing": "A permit is not required." Re-roofing is considered a repair, unless switching from a light roof covering, such as asphalt or wood shingles, to a heavy roof covering, such as concrete tiles, clay tiles or slate - that change "requires a permit and an engineered analysis of the roof structure, and may require additional reinforcement." The guidance adds material rules that still apply without a permit: no more than two layers of any type of covering; if two or more layers are in place, all layers must be removed before installing additional roofing; a composition roof may be installed over wood shingles (not over wood shakes) if the shingle manufacturer allows it; roof decking "shall be inspected by the roofer" with necessary repairs made, and "The City will not inspect this type of project." An ice barrier is 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 not less than 24 inches inside the exterior wall line.

Permit process note
The city's Residential Building Permit Exceptions and Guidance page (referencing Municipal Code 16.100.105.2) states under "Roofing and Re-Roofing": "A permit is not required." Re-roofing is considered a repair, unless switching from a light roof covering, such as asphalt or wood shingles, to a heavy roof covering, such as concrete tiles, clay tiles or slate - that change "requires a permit and an engineered analysis of the roof structure, and may require additional reinforcement." The guidance adds material rules that still apply without a permit: no more than two layers of any type of covering; if two or more layers are in place, all layers must be removed before installing additional roofing; a composition roof may be installed over wood shingles (not over wood shakes) if the shingle manufacturer allows it; roof decking "shall be inspected by the roofer" with necessary repairs made, and "The City will not inspect this type of project." An ice barrier is 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 not less than 24 inches inside the exterior wall line.
Adopted code
The city's Building Codes page states "Overland Park uses the 2024 International Building Codes package when reviewing building plans for commercial and residential projects," listing the International Building, Energy, Existing Building, Fire, Fuel Gas, Mechanical, Plumbing, Property Maintenance, and Private Sewage Disposal Codes and the International Residential Code for One- and Two-Family Dwellings, plus the 2017 National Electric Code.
Ice & water shield
Required — "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). About ice & water barrier
Mid-roof inspection
Not required — "Roof decking shall be inspected by the roofer and any necessary repairs should be made. The City will not inspect this type of project" (City of Overland Park, Residential Building Permit Exceptions and Guidance, "Roofing and Re-Roofing" section). Re-roofing and repair generally require no permit and no city inspection at all; only a switch from a light to a heavy roof covering, or structural roof-deck repairs, triggers a permit.
Impact-resistant roofing
Not required — Overland Park Municipal Code Chapter 16.310 "Residential Code," adopted by Ordinance No. BC-3513 (2026), incorporates the 2024 International Residential Code by reference as the city's general residential code and amends it through 32 numbered items running from Section 16.310.R101.1 through 16.310.E3902 -- administrative sections, the amended Table R301.2 climatic/geographic design criteria, structural and foundation sections R302-R405, deck sections R506-R507, energy sections N1103-N1111, plumbing section P2503.3, and electrical sections E3901-E3902. None of the 32 items touches IRC Chapter 9 (Roof Assemblies, R901-R908); Chapter 9 is adopted unamended. The only Chapter 9 cross-reference anywhere in the amendment package is a footnote to the amended Table R301.2 directing staff to mark a local-ice-damming-history designation by reference to 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 -- an ice-barrier designation, not an impact-resistance provision. A concurrent OPMC Chapter 16.110 "Residential Code for One- & Two-Family Dwellings," most recently amended by Ordinance No. BC-3499, Section 49 (2026), keeps the 2018 International Residential Code in force as an available option for single-family homes under 2,500 square feet built on their own separate lot; its 51 numbered items run from Section 16.110.R101.1 through 16.110.M1502.4.2 and likewise never reach Chapter 9. No UL 2218, Class 4, or impact-resistance provision appears in either chapter's amendment package.
Repair permit threshold
"A permit is not required. Re-roofing is considered a repair and may not require a permit unless you are switching from a light roof covering, such as asphalt or wood shingles, to a heavy roof covering, such as concrete tiles, clay tiles or slate. Changing from a light to a heavy roof covering requires a permit and an engineered analysis of the roof structure, and may require additional reinforcement" (City of Overland Park, Residential Building Permit Exceptions and Guidance, "Roofing and Re-Roofing" section). Separately: "Roof Deck: Repair / Replacement: A permit is required only if structural repairs are necessary."
Wind design criteria
Under the current 2024-IRC-based Residential Code (OPMC 16.310.R301.2, Table R301.2 "Climatic and Geographic Design Criteria," adopted by Ordinance No. BC-3513): 110 mph ultimate design wind speed (3-second gust); topographic effects No; special wind region No; windborne debris zone No; Seismic Design Category B. Exposure category is not a table column; per footnote (d), "Wind exposure category shall be determined on a site-specific basis in accordance with Section R301.2.1.4." Note: OPMC also retains a separate, older 2018-IRC-based code (Chapter 16.110) that applies only to new single-family residences under 2,500 sq ft of total livable floor area built on their own separate lot (per the note at OPMC 16.310.100, citing Kansas Statute); under that legacy table (OPMC 16.110.R301.2(1)), the wind speed is 115 mph, with the same No/No/No topographic/special wind region/windborne debris zone values and Seismic Design Category A.
Roof layer limit / recover
"No more than two layers of any type of covering may be placed on a roof. If two or more layers of roofing are in place, all layers must be removed before installing additional roofing." Additionally, "Adding an additional layer of roof covering is not permitted in the following conditions: Where existing roof or roof covering is water soaked or has deteriorated to the point that the existing roof or roof covering is not adequate as a base for additional roofing. Where the existing roof covering is slate or clay. Cement or asbestos-cement tile. Where the existing roof has two or more applications of any type of roofing covering." (City of Overland Park official "Residential Building Permit Exceptions and Guidance" page, "Roofing and Re-Roofing" section, citing IRC R908.3.1.1. The odd "clay. Cement" punctuation is reproduced verbatim as published.)
Deck & sheathing requirements
"Roof Deck: Repair / Replacement - A permit is required only if structural repairs are necessary." "Roof decking shall be inspected by the roofer and any necessary repairs should be made. The City will not inspect this type of project." Separately, re-roofing is treated as routine maintenance exempt from a floodplain development permit except where "the sheathing or joists underneath the roofing materials are replaced or other structural repairs are necessary." (City of Overland Park official "Residential Building Permit Exceptions and Guidance" page, "Roof Deck: Repair / Replacement" and "Floodplain Development Permits" sections.) No solid-sheathing material/gap specification (IRC R803-type language) was found in the OPMC 16.110/16.310 residential code amendments -- this field covers only the deck-replacement/inspection trigger, not a sheathing material spec.
Sales & use tax
Overland Park's combined sales tax rate is 9.35% (KS state 6.5% + Johnson County 1.475% + City of Overland Park 1.375%). KDOR Pub. 1700 lists 28 CID/TDD/STAR-bond special districts -- an unusually dense stacking -- ranging up to 11.35% (Edison CID) within specific addressed parcels -- the Prairiefire STAR Bond + CID area is 10.85%. Per Kansas DOR Pub. KS-1525 "Sales & Use Tax for Contractors, Subcontractors, and Repairmen" (Rev. 7-29-25): "Services performed to install or apply tangible personal property are exempt from sales tax when the services involve the original construction, reconstruction, restoration, remodeling, renovation, repair or replacement of a residence" -- so residential re-roof LABOR is exempt, but materials are not: contractors "are considered to be the final user or consumer of the materials they install for others, and must pay Kansas sales or use tax on them" at the time of purchase (or self-assessed compensating use tax on out-of-state materials, via Form CT-10U, per the same publication's Compensating Use Tax section). Commercial re-roof labor is taxable ("roofing, siding and guttering" is listed as a taxable labor service on commercial projects). Pub. KS-1525 describes only two collection points for contractor materials tax -- retailer sale or self- assessed use tax -- with no mechanism tied to building-permit issuance anywhere in the publication; Kansas sales/use tax is administered centrally by KDOR, not self-collected by home-rule cities as in Colorado.
