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 CONTRACTOR LICENSE AND BOND ON TOP OF THE STATE LICENSE. The City's Contractors page says "All contractors and subcontractors working in the City of Northlake must be registered with the City," and asks for a Contractors License Application "with the annual $100.00 fee, as well as a $10,000 bond and a Certificate of Insurance naming the City of Northlake as the holder."

Adopted code
THE 2021 INTERNATIONAL RESIDENTIAL CODE WITH CITY AMENDMENTS, PER THE TITLE 8 TEXT THE CITY POSTS. The City's Building Department page says "The City of Northlake follows the 2021 International Building Codes" and links a 145-page copy of Title 8, Building Regulations, whose file name is dated August 13, 2025, and which shows the update as marked changes to the older text. In it, Article H adopts the 2021 International Residential Code, which "is hereby adopted as the One and Two Family Dwelling Code of the City," with City amendments that include a replacement Table R301.2, climatic and geographic design criteria, which this listing could not read reliably from the posted copy. A City news item dated February 6, 2026 says "The City of Northlake has officially adopted the 2021 International Building Code." Neither page gives the adopting ordinance number. The codified Code Book is hosted on a third-party code library that this listing did not read.
Sales & use tax
Illinois taxes the roofer, not the job, and the operative rate is not keyed to the Northlake job address. Under 86 Ill. Adm. Code 130.1940(c), a construction contractor "does not incur Retailers' Occupation Tax liability as to receipts from labor furnished and tangible personal property (materials and fixtures) incorporated into a structure," but "incurs Use Tax on the cost price of the tangible personal property that is incorporated into real estate," with "roofing materials" named in the rule's own list of examples. Repair and replacement are taxed identically: 130.1940(a)(3) defines "construct" to include "repair, renovate or remodel." The Illinois Department of Revenue states the Use Tax rate as "6.25% of the purchase price or fair market value, whichever is greater." Where the contractor buys for resale, the local tax follows "the place of business at or from which the contractor or builder handles the transaction" (130.2075(b)(3)), so the combined rate on materials is the supply house's or the contractor's, which this record does not pin down. The authoritative lookup is the Illinois Department of Revenue's MyTax Illinois Tax Rate Finder.
