Roofing permits & building code in Wentzville

Missouri has no statewide roofing or general-contractor license, so licensing and registration are handled at the local level — always confirm the current requirements with the authority before starting work.
Contractor registration
Required
Adopted building code
International Residential Code (IRC), 2021 Edition, adopted by Sec. 500.070 of the Wentzville Municipal Code (Ord. No. 3689, repealed and replaced/most recently amended by Ord. No. 4460, § 1, 1-24-2024), with local amendments in Sec. 500.080 (most recently amended by the same ordinance, 1-24-2024). ESCALATION/EDITION FLAG: the city's separate Resolution No. 23-1953 (adopted 10-25-2023, "Regarding the Policy of the City of Wentzville, Missouri, on Workmanship, Siding Repairs, and Water Resistive Barriers") cites "the 2015 International Property Maintenance Code (IPMC) and the 2015 International Residential Code (IRC)" -- that resolution predates the city's 1-24-2024 adoption of the 2021 IRC/IPMC editions (Sec. 500.070/500.270) by about three months and has not been updated to reference the current editions, even though it remains in effect. Its substantive content (workmanlike-repair standard, damaged plane/elevation matching requirement, fastener specs) does not depend on edition-specific section numbers that are known to have changed, but the citation itself is stale.
Registration details
- license: City of Wentzville Building Permits page: "All contractors, generals and subs, are required to have a City issued contractors license prior to performing work in the City, this is required to be renewed every year by February 28. If your contractor's license is not valid, please fill out the Contractors License application and submit as directed on the application to assure efficient permit review times." Administered by the City Clerk's office ((636) 327-5101). This is a general contractor's license required of all contractors (generals and subs) performing work in the city, not a roofing-specific trade license; no separate roofing-specific license category was found. Annual renewal deadline: February 28.
Permit process
Sec. 500.070/500.080 (2021 IRC as amended) does not list "reroofing" or "re-covering of asphalt shingle roofs" among the R105.2 Work Exempt From Permit "Building" items (the amended list covers only: (1) small detached accessory structures =120 sq ft; (2) fences, which the city's amendment affirmatively states DO require a permit ["All fences require a permit"]; and (11) flatwork other than driveways). No City of Wentzville document was found that either explicitly requires or explicitly exempts a permit for asphalt-shingle re-roofing specifically -- the Building Division's own "Building Permits" page lists a non-exhaustive "Miscellaneous Permits" list (accessory building, deck/ patio cover, driveway, fence, finished basement, pool/hot tub, electric/ plumbing/HVAC, retaining walls over 4', sewer/water, solar, remodels, building additions) that does not include roofing/reroofing, but the page states this list "is not all encompassing." Separately, Resolution No. 23-1953 (10-25-2023) sets workmanship/matching standards for repairs to damaged siding and shingles (see roof_layer_limit note) but does not state a repair-size permit threshold. ESCALATION: roofing_permit_required and repair_permit_threshold are OMITTED for Wentzville rather than guessed -- recommend an architect browser pass to check the SmartGov permit-type list directly or call the Building Division (636-327-5101) to confirm whether asphalt-shingle re-roofing requires a permit.
