Roofing permits & building code in Sterling

Roofing permit and contractor-licensing rules in Sterling are set locally by City of Sterling Building and Zoning Department. 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 2021 INTERNATIONAL RESIDENTIAL CODE WITH LOCAL AMENDMENTS, PER THE CITY'S OWN BUILDING AND ZONING PAGE. The page says "The following codes are enforced in the City of Sterling" and lists "2021 International Residential Code for one- and two-family dwellings" alongside the 2021 International Building, Existing Building and Property Maintenance Codes, "All with local amendments," plus the Illinois Energy Conservation Code. The amendments are codified in the City Code, which the City publishes through an outside code host and which this record did not read, so it does not state 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.
  • city_level: A CITY REGISTRATION ON TOP OF THE STATE LICENSE. The City's Contractor Registration page sets a "REGISTRATION FEE $50.00," a certificate of insurance naming "City of Sterling/Building Department" as holder, and a "$15,000 License Bond honoring the City of Sterling," and lists "Proof of Valid License Required for: Roofing."
Permit process
The City's Building and Construction Permits page says "All building permits are issued through the Building & Zoning Department" and asks owners to call, stop by the office or write "before beginning work to ensure a smooth process." It says "Residential Roofing Permits are based on the cost of the project," and the City's 2025 permit fee schedule prices "ROOFING, SIDING- AT COST" on a sliding scale that starts at $24.00 for "Work up to $500.00." The page does not say in terms which roofing jobs need a permit, so this listing does not state a yes or no answer for a re-roof. Online building permit applications are filed through the City's Building Permit Portal.
