  • 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 note
A RE-ROOF REQUIRES A PERMIT, PER THE BUILDING DEPARTMENT'S OWN GUIDE. Under "ROOFING," the Homeowner Project Guide (updated July 14, 2026) says "A building permit is required. The permit fee is $75.00 for single-family or townhome," and permits are applied for online. The guide's general section adds a $25 permit application fee to every application, says a list of required inspections is provided with the permit, and says "PERMITS EXPIRE ONE (1) YEAR FROM THE DATE OF ISSUE OR AT SIX (6) MONTHS IF THE PROJECT HAS NOT STARTED." The guide says it is the Village's goal to issue smaller permits in five days or less.
Adopted code
THE 2024 INTERNATIONAL RESIDENTIAL CODE WITH LOCAL AMENDMENTS, PER THE BUILDING DEPARTMENT'S HOMEOWNER PROJECT GUIDE. The guide, updated July 14, 2026, lists among the construction codes the Village uses for all types of construction the 2024 International Residential Code with local amendments, the 2024 International Building Code with local amendments and the 2024 International Energy Conservation Code with State of Illinois amendments. The guide says its contents come from "Codes and Ordinances adopted by the Village" and, for the amendments, tells readers to "select Municipal Code and Ordinances; Title 16 Building" and Construction. The amendments are codified in Title 16 of the Village Code, which this record did not read, so it does not state the adopting ordinance or whether the Village has amended the IRC's roof provisions.
Ice & water shield
Required — REQUIRED, IN THE BUILDING DEPARTMENT'S OWN WRITTEN WORDS. The Homeowner Project Guide says, under "ROOFING," "An approved ice and water underlayment barrier is required and must extend from the lowest edges of all roof surfaces to a point at least twenty-four inches" inside the exterior wall line of the building. This rests on the department's own written guide; the Village's enacted amendment text in Title 16 was not read. About ice & water barrier
Roof layer limit / recover
The Building Department's Homeowner Project Guide says, under "ROOFING," "Maximum of two (2) layers of asphalt shingles (235 lb. weight) can be installed on a roof," and "Asphalt shingles may not be installed on a roof pitch less than 3:12." This rests on the department's own written guide; the enacted amendment text in Title 16 was not read.
Sales & use tax
Illinois taxes the roofer, not the job, and the operative rate is not keyed to the Mundelein 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.
