Roofing in DeKalb, Illinois

Yes, a permit is required to replace a roof in DeKalb, IL, issued by City of DeKalb Building & Code Compliance Division. THE CITY PUBLISHES ITS OWN ROOFING PERMIT APPLICATION. The Building Permits & Fees page lists a "Roofing Permit Application" among its downloadable permit forms and says "Both homeowners and contractors are required to register for a BS&A Online Account in order to apply for building permits online" and "All online submissions require a completed permit application from the list below to be uploaded with the submittal." The application asks for the project valuation and has the applicant choose between "ROOF RECOVER" and "ROOF REPLACEMENT," the second being where "the Existing Roof Covering is being removed while repairing any damaged substrate, and installing a New Roof Covering." It asks whether sheathing is being replaced and how many square feet, asks for an image of the roof cross section and a materials list, and has the contractor represent that "they are a State of Illinois Licensed Roofing Contractor doing the roofing work" and provide a copy of the license. The form, dated September 2021, refers to "the 2015 International Residential Code," an older edition than the 2021 code the City now lists.

Roofing permits & building code in DeKalb

Roofing permit and contractor-licensing rules in DeKalb are set locally by City of DeKalb Building & Code Compliance Division. 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.
