Roofing permits & building code in Waterloo

Roofing permit and contractor-licensing rules in Waterloo are set locally by City of Waterloo Building and Inspection 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 2006 INTERNATIONAL RESIDENTIAL CODE, WITH REVISIONS, PER THE CITY'S OWN PAGES. The City's Building Permits page says "The City of Waterloo has adopted the following as Building Codes for residential and commercial construction" and lists the "2012 International Building Code, with revisions" and the "2006 International Residential Code, with revisions." The residential permit application, revised July 2025, says "The City of Waterloo has adopted the 2006 International Residential Code with revisions" and to "Consult Chapter 6, Building Code, of the City of Waterloo Code of Ordinances for details." Chapter 6 is published by an outside code host, which this record did not read, so it does not state what the City's revisions say about roofs.
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 "Building Permits are required for the following construction" and lists a principal building, accessory buildings such as sheds 50 square feet and over, swimming pools, decks, and retaining walls over 4 feet high. The list does not name roofing or a roof replacement, and the page does not say either way whether a re-roof needs a permit, so this listing does not state a yes or no answer. The City's residential application says "Plumbers and roofers must be licensed by the State of Illinois" and "All utility connection fees, inspection fees and building fees must be paid before the building permit can be issued." The Building and Inspection page says "There is a 48 hour notice needed to be given to the Building Inspector to assure your project will be inspected."
