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, BOND AND INSURANCE ON TOP OF THE STATE LICENSE. The Village's Forms / Permits page asks contractors to send a registration PDF that "should include the following: Contractor Registration Application," "COI (Village of Carpentersville as Cert Holder)," "$10k Surety Bond" and "Licenses (Roof/Plumbing/Electric etc.)," and says "Sub contractors must also register."
Permit process note
The Village's "When Permits Are Required" handout (revised August 28, 2017) lists "Roofing: OTC" among the work that requires a permit, with OTC marking a permit that may be issued over the counter. The Village's Residential Permit Guide lists a roof replacement permit fee of $50, "payable at the time of issuance," and a $60 fee for re-inspections. The submittal checklist asks for the Residential Building Permit Application, a proposal to include specifications, and a copy of a valid roofing license or affidavit, and the only inspection listed is a final inspection once all work is complete.

Adopted code
THE 2018 INTERNATIONAL RESIDENTIAL CODE IS THE EDITION THE VILLAGE'S PERMIT GUIDE APPLIES; THE ADOPTING ORDINANCE WAS NOT READ. The Village's Residential Permit Guide says equipment must be installed "in accordance with the manufacturer's installation instructions, the 2018 International Residential Code, the 2021 Illinois Energy Conservation Code and the 2017 National Electric code," and its Roof Replacement section says "Ice and water shield required per 2018 IRC." The guide does not itself say the Village adopted that edition. The Village's Municipal Code is hosted outside the Village's own site, which this record did not read, so it does not state the adoption ordinance or whether the Village has amended the IRC's roof provisions.
Ice & water shield
Required — REQUIRED, PER THE VILLAGE'S OWN PERMIT GUIDE. The Residential Permit Guide's Roof Replacement section lists "Ice and water shield required per 2018 IRC." This rests on the department's written guide; the Village's Municipal Code amendments were not read. About ice & water barrier
Roof layer limit / recover
THE VILLAGE'S PERMIT GUIDE LIMITS ROOFING TO TWO LAYERS. The Residential Permit Guide's Roof Replacement section lists as a minimum requirement "Maximum of two layers of roofing permitted."
Sales & use tax
Illinois taxes the roofer, not the job, and the operative rate is not keyed to the Carpentersville 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.
