Roofing permits & building code in Mount Vernon

Roofing permit and contractor-licensing rules in Mount Vernon are set locally by City of Mt. Vernon Engineering and Inspections Office. Illinois licenses roofing contractors at the state level: under the Roofing Industry Licensing Act (225 ILCS 335) no roofing work may be done except by a state-licensed roofing contractor or qualifying party, with a limited license for residential properties of 8 units or less and an unlimited license for everything else, and a city or county that requires a building permit may not issue one to a roofing contractor without proof of current state licensure, while some cities add their own contractor registration on top — always confirm the current requirements with the authority before starting work.

Contractor registration
Required
Adopted building code
THE CITY'S OWN PAGES CONFLICT ON THE RESIDENTIAL CODE. The City's Application for Building Permit has the applicant agree to build "in strict compliance with all provisions of the International Building Code, 2021 Edition; International Existing Building Code, 2021 Edition; International Residential Code for One and Two Dwellings, 2021 Edition," and says "Copies of the above Codes and Ordinances adopted by the City of Mt. Vernon are on file in the Office of the City Clerk." The City's Building Codes page, under "What Codes Do We Follow?," lists the "International Building Code (IBC) - 2021 Edition" and "International Existing Building code (IEBC) - 2021 Edition" but no residential code, and says "Exception: One- and two-family homes do not need to follow these codes." Chapter 150 of the City Code, Buildings, is hosted on American Legal Publishing and was not read for this listing, so it does not resolve which statement governs a house or whether the City has amended the IRC's roof provisions.
Registration details
  • state_level: Illinois licenses roofing contractors statewide with no dollar threshold. 225 ILCS 335/9(2): "No work involving the construction, reconstruction, alteration, maintenance, or repair of any kind of roofing or waterproofing may be done except by a roofing contractor or a qualifying party licensed or credentialed under this Act." Under 225 ILCS 335/5(a-3), "A municipality or a county that requires a building permit may not issue a building permit to a roofing contractor unless that contractor has provided sufficient proof of current licensure as a roofing contractor by the State," and a holder of a limited license is restricted to permits for work on residential properties of 8 units or less. The Illinois Department of Financial and Professional Regulation lists "Roofing Contractor, Licensed" among the professions it licenses.
Permit process
The City's Building Permits page says "Many small repairs don’t need a building permit, but bigger projects often do" and that "All permitted work must be inspected." Its list of projects that need a permit names carports, garages, pools, storage buildings, new houses, mobile homes, new commercial construction and "Porches and decks that are over 30 inches high or have a roof," and adds "This is not a full list. If you are not sure whether your project needs a permit, contact the Engineering and Inspections Office for help." The page does not name roof replacement either way, so this listing does not state a yes or no answer for a re-roof. The City's building permit application has lines for a "Roofer" and "Roofer Address," and the page says permit fees "are based on the cost of the project."
