Roofing permits & building code in Blaine

Roofing permit and contractor-licensing rules in Blaine are set locally by City of Blaine, Minnesota - Building Inspections Division. Minnesota requires a state Residential Roofer (RR) license from the Department of Labor and Industry to contract residential roofing work — roofing is expressly excluded from the single-special-skill exemption other trades can use, and the only relief is an affirmative Certificate of Exemption for small operators — and the Minnesota State Building Code applies statewide, so a city cannot adopt different roofing-code provisions, only its own permit administration and fees — always confirm the current requirements with the authority before starting work.

Roofing permit
Required
Contractor registration
Required
Adopted building code
City of Blaine Code of Ordinances, Chapter 18 (Buildings and Construction), Article II (Construction Codes and Regulations), Division 1, Sec. 18-19 ("State building code; adopted by reference"), read in full, codified through Ordinance No. 25-2596 (enacted January 5, 2026, Supp. No. 2) per the city's Municode banner: "The most current edition of the state building code, as adopted by the department of labor and industry pursuant to M.S.A. § 326B.101 et seq., including all of the amendments, rules and regulations established, adopted and published from time to time by the department of labor and industry, through the construction codes and licensing division, is hereby adopted by reference including chapter 1306 with options 1306.0020, subpart 2, and 1306.0030 E, option 1." The section's own ordinance history runs from Ord. No. 410 (1974) through Ord. No. 07-2137 (7-19-2007), but its self-updating "most current edition... as amended from time to time" language means Blaine automatically tracks whatever residential code edition the state currently has in force -- currently the 2020 Minnesota Residential Code (Minn. R. ch. 1309), which incorporates the 2018 IRC. Sec. 18-20 confirms application, administration, and enforcement follow the state building code, enforced by a state-certified building official designated by the city. Minnesota law (Minn. Stat. § 326B.121, subd. 1(a)-(b)) makes the State Building Code the standard that applies statewide and supersedes any municipal building code; subd. 2(c) bars a municipality from imposing building-code provisions that differ from the State Building Code.
Registration details
  • license: Minnesota has a statewide mandatory Residential Roofer (RR) license, per Minn. Stat. § 326B.805, subd. 1: "A person who meets the definition of a residential roofer as defined in section 326B.802, subdivision 14, must be licensed by the commissioner as a residential roofer, residential building contractor, or residential remodeler," enforced statewide (subd. 3) with a $15,000 gross-annual-receipts exemption threshold (subd. 6(5)) requiring an affirmative Certificate of Exemption; roofing is excluded from the general single-special-skill exemption available to other trades (subd. 6(8)). Administered by MN DLI, not the City of Blaine. Locally, City of Blaine Code of Ordinances Sec. 18-408(b) requires that "no person shall perform electrical, manufactured home installation, plumbing, water conditioning, roofing, residential remodeling, residential building, well water contracting work, septic system work, or any other work requiring a state-issued license for another within the city without first having provided a copy of their state-issued license," and that every such licensee "shall have on file with the building official a copy of the current license." Sec. 18-408(a) requires a separate City of Blaine general contractor's license only for a listed set of trades that includes "Commercial roofing" -- residential roofing is not on that list, so Blaine imposes no additional city-level contractor license on top of the state RR license for RESIDENTIAL roofing work, only a requirement to file proof of the state license. Blaine's own Contractor Licensing and Registration page confirms: "Residential Contractors doing residential home improvement projects will need to be licensed by the state for such projects as:... Roofing..." and separately notes city licensing applies to a different list of trades (furnace replacement, ductwork, air conditioner replacement, gas fireplace installation, boiler installation, garage heaters, sewer and water work) that does not include roofing. All contractors, including those only filing a state license, must also register as a user in Blaine's online iMS permitting system to pull a permit.

Inspections
Per Blaine's Roofing/Siding/Stucco permit page, the Roofing permit's typical inspections are "Roofing Pictures (ice and water)" and "Final," though the page notes "depending on your project, inspections may be added or removed." Blaine's own "Residential Roofing" reference handout describes the mechanics: the applicant uploads digital photographs to the permit's Files tile in the iMS system, with one photograph required each of: roof decking, all ice and water protection, all flashing details, all vents, the finished roof detail, and the front of the house showing the address. Hard-copy photographs are not accepted and must be converted to digital format first. "A final inspection will be automatically scheduled after the required photographs have been submitted and approved by the City," and that final inspection "is conducted by site visit only," with fenced-yard access required. Roof decks found rotted or otherwise unsound must be repaired before reroofing, and "a site inspection or digital photographs of repairs will be required" for that repair work specifically.
