Adopted code

City of Crest Hill Building Department

Yes, a permit is required to replace a roof in Crest Hill, IL, issued by City of Crest Hill Building Department. THE CITY TREATS A ROOF REPLACEMENT AS PERMITTED WORK. The Building Department's page says "MOST PROJECTS, RESIDENTIAL AND COMMERCIAL, REQUIRE A PERMIT," lists "Roofs (Residential)" among its permit information sheets for common projects, and under "Roof Repair Policy" says the adopted code "must be followed by both residents and contractors replacing roofs." The department's Roofing Permit Checklist says the building permit or a copy must be kept on the site of the work, "conspicuously posted and visible from the public right-of-way," that failed inspections are subject to re-inspection fees, and that "Patching asphalt shingles is not allowed"; the minimum "area allowed to be re-roofed is a full slope." The page warns that a door-to-door contractor must "still have to be registered and get a permit to do work at your property. Do not allow work to begin on your property before you have a permit!" Payments "may be made by check, by mail, or placed in the drop box (located outside City Hall), or by check, cash, or card in person at City Hall," and "We do not accept online or phone payments at this time.".

Adopted code
THE 2015 INTERNATIONAL RESIDENTIAL CODE, PER THE BUILDING DEPARTMENT'S OWN PAGE. The page says "We have adopted the 2015 IBC/IRC and 2020 NEC. State Codes: Illinois Plumbing Code, Illinois Accessibility Code, and Illinois Energy Code," and that "City of Crest Hill Ordinance 15.04.010 Conformance with National and State Codes states the city has adopted the 2015 International Building Code." It adds that "it is expected that the 2021 IBC/IRC and 2024 IFC will be adopted before the end of 2026." The City posts Title 15, Buildings and Construction, and its update to Section 15.04.010 as PDFs, but this record could not extract their text, so it does not quote the adopting ordinance or state whether the City has amended the IRC's roof provisions.
Drip edge
Required — REQUIRED, IN THE DEPARTMENT'S OWN WRITTEN CHECKLIST. The Roofing Permit Checklist says "Provide a drip edge (gutter apron) under the ice and water shield at eaves and above underlayment at rakes. (R905.2.8.5)" and adds that it should "overlap a minimum of 2 inches." This rests on the department's own written sheet; the City's enacted code text in Title 15 was not read. About drip edge
Ice & water shield
Required — REQUIRED, IN THE DEPARTMENT'S OWN WRITTEN CHECKLIST. The Roofing Permit Checklist says "Ice dam protection is required and shall extend from the roof edge to 24 inches beyond the exterior wall line. (R905.2.7.1)" This rests on the department's own written sheet; the City's enacted code text in Title 15 was not read. About ice & water barrier
Roof layer limit / recover
The department's Roofing Permit Checklist says "No more than two roof layers are permitted. (R907.3)" This rests on the department's own written sheet; the City's enacted code text in Title 15 was not read.
Deck & sheathing requirements
The department's Roofing Permit Checklist says "Roof sheathing shall be repaired or replaced if damaged. If more than six" 4-foot by 8-foot "sheets of an existing roof line require replacement, the entire roof line sheathing shall be replaced with" 5/8-inch "Ply or OSB," with the exception "not required for shared roofs." It also says plank boards and 3/8-inch sheathing are "NOT allowed to be patched or repaired. If the roof deck is in sound condition (no holes, water damage or excessive deflection) you can overlay the plank boards with" 1/2-inch "ply or OSB otherwise the plank board must be removed and re-decked with" 5/8-inch "ply or OSB. (R905.2.1)" This rests on the department's own written sheet; the City's enacted code text in Title 15 was not read.
Sales & use tax
Illinois taxes the roofer, not the job, and the operative rate is not keyed to the Crest Hill 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.
