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 AND A $40 FEE ON TOP OF THE STATE LICENSE. The Village's Contractor Registration page says "All contractors working within the Village of Niles are required to be registered with the village" and "Contractor Registrations expire every fiscal year on April 30th." Its table lists a Roofing Contractor as needing a "Copy of State Roofing License" with a $40 fee and no surety bond, and the page says the Community Development Department "typically processes Contractor Registration at the time of permit application."

Adopted code
THE 2024 INTERNATIONAL RESIDENTIAL CODE WITH LOCAL AMENDMENTS, PER THE VILLAGE'S OWN CODES PAGE. The Village's Codes & Amendments page says "The Village of Niles has adopted the following codes" and lists the "2024 International Residential Code," the "2024 International Existing Building Code" and the "2024 International Energy Conservation Code," with a link to Local Code Amendments. The amendments are codified in Chapter 18 of the Village Code, which this record did not read, so it does not state whether the Village has amended the IRC's roof provisions. The Village's Roof Permit Conditions sheet quoted below was revised in February 2023, before the 2024 edition appears on the codes page.
Ice & water shield
Required — REQUIRED, 36 INCHES INSIDE THE WALL LINE AND IN VALLEYS, PER THE VILLAGE'S OWN SHEET. The Village of Niles Roof Permit Conditions (revised 2/2023) state: "Self-adhesive ice/water shield product shall be applied to a point" 36 inches "inside the exterior wall line of the building and valleys," and add "Therefore, 5' may be needed. Follow manufactures installation instructions." The sheet's diagram note says the material "will start at the edge of the eve." This rests on the department's own written sheet; the enacted amendment text was not read. About ice & water barrier
Mid-roof inspection
Required — AN ICE/WATER SHIELD INSPECTION BEFORE THE FINAL, PER THE VILLAGE'S OWN SHEET. The Village's Roof Permit Information sheet lists "Required Inspections" as "Ice/water shield inspection" and "Final Inspection," with the owner not needing to be on site. This rests on the department's own written sheet; the enacted amendment text was not read.
Roof layer limit / recover
TWO LAYERS AT MOST, PER THE VILLAGE'S OWN ROOF PERMIT CONDITIONS. The Village of Niles Roof Permit Conditions (revised 2/2023) state: "A maximum of 2 layers of roofing are allowed" and "If there are two existing roofs, they must be stripped down to the original sheathing." This rests on the department's own written sheet; the enacted amendment text was not read.
Deck & sheathing requirements
The Village of Niles Roof Permit Conditions (revised 2/2023) state: "If any sheathing or flashing is rotted or damaged, it must be replaced." They also require shingles to be "fastened with non-corrosive nails or staples, penetrating a minimum of" three-quarters of an inch "into sheathing - or through the thickness of the sheathing, whichever is less," with "4 per 36-40 inch strip." This rests on the department's own written sheet; 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 Niles 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.
