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: The City's Building Inspections page says "It is not permitted for anyone to do work on anyone else's property unless they are licensed/registered with the City of Pekin Building Division." The page does not say whether a State-licensed roofer must also register with the City.
Permit process note
A PERMIT IS REQUIRED FOR A TEAR-OFF AND RE-ROOF AND FOR AN OVERLAY. The City's FAQ answer to "I need a permit for installing a new roof?" says "Yes, a roofing permit is required for the complete tear-off and replacement of shingles and for the installation of a second layer of shingles over an existing roof." The Building Inspections page lists "Roofing of any existing structure" under "When Permits Are Required" and says "New buildings, additions, alterations, and renovations all require a building permit before you get started." It says "any inspection requested before 4 p.m. will be completed the following business day" and that a homeowner may do work on his or her own residence, "but a permit must still be obtained." The City's pages do not state a roofing permit fee.
Adopted code
THE 2024 INTERNATIONAL RESIDENTIAL CODE, PER THE CITY'S PERMITS AND BUILDING CODES PAGE; THE CITY'S OWN PAGES DIFFER ON THE EDITION. The Permits, Building Codes & Contractor Information page lists "Adopted Building & Life Safety Codes," beginning with the "2024 International Residential Code," and says "The City of Pekin currently operates under the 2024 editions of the International Building Codes with local amendments." The same list names the "City of Pekin Municipal Building Code (pending update to 2024 I-Codes)." The City's Building Inspections page says "The City of Pekin currently operates under the 2015 version of the International Building Codes." The local amendments are in the City of Pekin Municipal Code, which this record did not read, so it does not state which edition the enacted code names or whether the City has amended the IRC's roof provisions.
Roof layer limit / recover
The City's FAQ says a roofing permit is required "for the installation of a second layer of shingles over an existing roof," so the City permits an overlay with a permit. The City's pages do not state a maximum number of layers.
Sales & use tax
Illinois taxes the roofer, not the job, and the operative rate is not keyed to the Pekin 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.
