Roofing permits & building code in St. Charles

Roofing permit and contractor-licensing rules in St. Charles are set locally by City of St. Charles - Community Development Department (Building Division). 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.

Adopted building code
Ordinance No. 22-153 (Bill No. 13548, passed December 6, 2022) rewrote Code of Ordinances Section 500.070 so that "The 2021 International Residential Code for One- and Two-Family Dwellings, including Appendices A, B, C, D, G, H, J, K, N, and P, except as otherwise provided in this Chapter, as published by the International Code Council, Inc., is adopted by reference as the One- and Two-Family Dwelling Code of the City." The city's Construction Code Listing gives the codes as effective January 1, 2023. The local amendment list in Section 500.080 (items 1 to 84) was read in full. In Chapter 9, Roof Assemblies, it rewrites only Section R905.2.8.2 (valley linings) and Section R905.2.8.5 (drip edge); it does not amend the reroofing section, R908. It also rewrites the Section R105.2 list of work exempt from permit, which names no roofing work, and fills in Table R301.2(1).
Permit process
The Building Division page lists "Replacing roof shingles" among work that "Generally, projects that DO NOT require permits include," and lists new construction, additions, remodels and decks among projects that generally do require permits. The page does not address a full tear-off, a change of roofing material, or structural repair, so the department should be asked about those.
