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.

The Village's Re-Roofing page says "All contractors listed on no-fee permits must still be licensed in accordance with Title 3, Chapter 8 of the Village Code."

Adopted code
THE 2024 INTERNATIONAL RESIDENTIAL CODE IS THE EDITION THE VILLAGE'S OWN RE-ROOFING PAGE CITES; THE ADOPTING ORDINANCE WAS NOT READ. The Village's Re-Roofing page requires ice and water membrane "in accordance with 2024 IRC 905.1.2." The Village's Building Permits page says "Village of Mokena ordinances require that a building permit be obtained for most residential and commercial construction projects." The Village Code is on an outside code host, 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 VILLAGE'S OWN WRITTEN WORDS. The Village's Re-Roofing page says "Ice and Water membrane shall be installed in accordance with 2024 IRC 905.1.2 consisting of self-adhering polymer-modified bitumen sheet in place of normal underlayment and extend from the lowest edges of all roof surfaces to a point not less than 24 inches inside the exterior wall line of the building," and on roofs of 8 in 12 slope or more "the ice barrier shall also be applied not less than 36 inches measured along the roof slope from the eave edge of the building." This rests on the Village's own web page; the enacted amendment text was not read. About ice & water barrier
Sales & use tax
Illinois taxes the roofer, not the job, and the operative rate is not keyed to the Mokena 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.
