Roofing permits & building code in Missoula

Roofing permit and contractor-licensing rules in Missoula are set locally by City of Missoula Development Services, Building Division. Montana licenses construction contractors at the state level — since January 1, 2026 the Department of Labor and Industry’s Construction Contractor License under MCA Title 37, chapter 45 has replaced the old contractor registration, and the statute’s definition of a construction contractor expressly includes the installation or repair of roofing, with exemptions that include a job whose whole contract price is under $2,500 and an independent contractor with no employees — and a city or county may not require a second registration, licence or bond of a contractor the state covers, only a general business licence fee, while the state building code, apart from its energy provisions, does not reach a house of fewer than five dwelling units unless the city or county extends it by ordinance or resolution, a local government may enforce a building code only through a program the state has certified, and it may not adopt one more stringent than the state’s — always confirm the current requirements with the authority before starting work.

Required
Adopted building code
The City of Missoula adopts building codes by a FLOATING reference. Missoula Municipal Code 15.04.010(A), as currently codified (Ord. 3783, 2026; Prior Code and Ord. 1814), reads: "The current and future editions of the following model technical building construction codes, including, but not limited to the International Building Code, International Residential Code ... and all accompanying appendices, amendments, and modifications adopted or required to be adopted by the Montana Department of Labor Building Codes Bureau ... as amended from time to time by the Building Codes Bureau, are adopted by reference." Under 15.04.010(C), state amendments "become effective upon execution of an Administrative Rule by the Mayor as authorized by Section 50-60-301 MCA." Under 15.04.010(E), the adopted codes "are applicable within the corporate limits of the City of Missoula." The City's own Building Division page states the 2021 International Residential Code and 2021 International Building Code took effect September 1, 2022, consistent with the state's current edition under ARM 24.301.154. Title 15 was read in full (roughly 198,000 characters) and amends nothing in IRC Chapter 8 or Chapter 9; its only building-code amendments concern an unrelated 1997 Uniform Housing Code appeals-board section. This general, floating adoption does not itself state that it is "specifically applicable" to residential buildings containing fewer than five dwelling units, the language ARM 24.301.201(1) and MCA 50-60-102(1)(a) require to bring a house under the state building code; this record does not conclude either way on that point from the ordinance text alone. Because that applicability question is undetermined, this record omits the state-default roofing fields that depend on it (ice barrier, drip edge, impact resistance, deck sheathing, roof layer limit) rather than stamping them. Independent of that question, the City's own permit materials (see roofing_permit_required and repair_permit_threshold) confirm the City in fact issues and fees residential roofing permits.
Registration details
  • state_level: Montana licenses construction contractors at the state level under MCA Title 37, chapter 45 (Construction Contractors), enacted by House Bill 239 (Ch. 644, L. 2025) and effective January 1, 2026; the 2025 Montana Code Annotated prints the former Title 39, chapter 9 (Contractor Registration) as renumbered and repealed. MCA 37-45-201(1) reads: "An individual or business entity may not engage in business as a construction contractor without a current license from the department." MCA 37-45-102(1) defines "construction contractor" as, "except as provided in 37-45-104, a person, firm, or corporation that: (a) in the pursuit of an independent business, offers to undertake, undertakes, or submits a bid to construct, alter, repair, add to, subtract from, improve, move, wreck, or demolish for another a building, highway, road, railroad, excavation, or other structure, project, development, or improvement attached to real estate, including the installation of carpeting or other floor covering, the erection of scaffolding or other structures or works, or the installation or repair of roofing or siding". MCA 37-45-104 opens "As related to construction contractors, this chapter does not apply:" and its list includes "(8) to work or operation on one undertaking or project considered of a casual, minor, or inconsequential nature, by one or more contracts, the aggregate contract price of which, for labor and materials and all other items, is less than $2,500 a job. The exemption prescribed in this subsection does not apply when the work or construction is only a part of a larger or major operation, whether undertaken by the same or a different construction contractor, or in which a division of the operation is made into contracts of amounts of less than $2,500 a job for the purpose of evasion of this chapter or otherwise." and "(24) to an independent contractor who has no employees. However, an independent contractor may voluntarily elect to register under this chapter." Sections 37-45-104 and 37-45-204 were redesignated from former MCA 39-9-211 and 39-9-304 by Sec. 20, Ch. 644, L. 2025, without amendment, and both still use the words "register" and "registered". The Montana Department of Labor and Industry's Construction Contractor License program page states: "All construction contractors with employees must register." The Department's Construction Contractor License FAQ (rev. 05/19/2026) answers "Who needs a Construction Contractor License?" with: "Anyone involved in the construction, alteration, repair, moving, or demolition of structures attached to real estate. This specifically targets contractors with employees, as well as corporations and manager-managed LLCs, regardless of employee count." This record decides neither whether a given reader is inside either exemption nor how a job is priced against the $2,500 line.
  • city_level: MCA 37-45-204 reads in full: "The provisions of this chapter relating to the registration or licensing of a person, firm, or corporation, including the requirement of a bond with the state of Montana named as obligee and the collection of a fee, are exclusive for registered construction contractors. A political subdivision of the state may not require or issue any registrations, licenses, or bonds for the same or a similar purpose. However, this section does not limit or abridge the authority of a local government to levy and collect a general and nondiscriminatory license fee levied upon all businesses. This section does not limit the authority of a local government with respect to contractors not required to be registered under this chapter."
