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.
Permit process note
ROOF PERMIT FEES ARE WAIVED THROUGH APRIL 30, 2027, AND ROOF PERMITS CARRY NO INSPECTIONS UNDER THAT PROGRAM. A City notice dated March 5, 2026 says the City is "bringing back the Building Permit Holiday" and waives permit fees for listed projects "between March 5, 2026 thru April 30, 2027," including "Roof (NO INSPECTIONS)." It says "Direct out-of-pocket expenses associated with the permit processing, such as Plan Review fee and other third-party costs, would not be waived" and that "All construction must meet city codes, get zoning approval, and have required inspections." The City's Do I Need A Permit? page says "No building, electrical, mechanical, plumbing or sewer system shall be constructed, enlarged, altered, repaired, moved, demolished, or changed unless a permit has been obtained."
Adopted code
THE 2021 INTERNATIONAL RESIDENTIAL CODE, EFFECTIVE MARCH 1, 2025, PER THE CITY'S OWN CURRENT BUILDING CODES PAGE. Under the heading "Effective March 1, 2025," the page lists "International Residential Code 2021," "International Existing Building Code 2021" and "International Energy Conservation Code 2024," marked "Revised 2/26/25," and says "Please see local amendments above," linking a document titled "2018 Building Code Amendments." That document is Ordinance No. O-15-18, passed August 6, 2018, which at that time adopted the "2015 International Residential Code" in section 4-1-3-1 and amended it in only one respect, Section R-403.1, on pier footings; it contains no roofing amendment. This record did not read the ordinance that adopted the 2021 edition or the current text of Title 4 of the Darien City Code, so it does not state whether the City has since amended the IRC's roof provisions.
Repair permit threshold
A TEAR-OFF REQUIRES A PERMIT; AN OVERLAY UP TO TWO LAYERS AND ORDINARY REPAIR DO NOT. The City's Do I Need A Permit? page lists "Re-roofing - Tearing off old shingles" among the work for which permits are required, and lists, for a residential single family home, "Normal repair and maintenance," "Roof overlay - limited to a total of 2 layers of roofing material" and "Replacement of deteriorated materials" among the work for which permits are not required. The page is marked "Revised 12/19/2013." For multi-family buildings it says "All other multifamily construction may require permits."
Roof layer limit / recover
TWO LAYERS IN TOTAL. The City's Do I Need A Permit? page lists, among work on a residential single family home that needs no permit, "Roof overlay - limited to a total of 2 layers of roofing material." The page is marked "Revised 12/19/2013"; the City's enacted code text on roof layers was not read.
Sales & use tax
Illinois taxes the roofer, not the job, and the operative rate is not keyed to the Darien 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.
