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 VILLAGE REGISTRATION, AT NO FEE, BEFORE THE PERMIT IS RELEASED. The Village's Contractor Requirements page says "The contractors listed below must be registered with the Building Department before the permit can be released" and "No registration form or fee is required; however, the information listed below must be submitted." For a roofer it lists "A copy of current roofing license with the State of Illinois" and a "Certificate of insurance with minimum general liability of $500,000, listing the Village as Certificate Holder."

Adopted code
THE 2024 INTERNATIONAL RESIDENTIAL CODE, ADOPTED BY VILLAGE ORD. 2025-90, EFFECTIVE MARCH 1, 2026. The Village's Building Codes & Ordinances page lists, under "Adopted & Applicable Building Codes & Ordinances (Currently in Effect)," the "2024 International Residential Code for One and Two Family Dwellings" with "Village Ord. 2025-90" and an effective date of March 1, 2026. This record did not read Ord. 2025-90 itself (the page's link to it does not open a document), so it does not state whether the Village has amended the IRC's roof provisions.
Roof layer limit / recover
ONE OVERLAY OF ASPHALT OR FIBERGLASS SHINGLES AT MOST, PER THE VILLAGE'S OWN PERMIT PAGE. Under Reroof, the Village's Building Permits page says: "Not more than one layer of asphalt or fiberglass shingles shall be applied over an existing asphalt or fiberglass shingle roof; asphalt or fiberglass shingles shall not be applied over existing wood shingles or shakes. No second layer of wood shingles or shakes is permitted." It adds: "Asbestos - cement shingles are prohibited." This rests on the department's own published guidance; the enacted amendment text was not read.
Sales & use tax
Illinois taxes the roofer, not the job, and the operative rate is not keyed to the Gurnee 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.
