Adopted code

City of Geneva Building & Zoning Division

Yes, a permit is required to replace a roof in Geneva, IL, issued by City of Geneva Building & Zoning Division. THE CITY SAYS A ROOF REPLACEMENT REQUIRES A PERMIT. The Building Division's Roof Replacement Permit Information sheet, revised November 19, 2025, says "A building permit is required prior to replacing a roof," and the City's Permits page lists "Roof" among its required building permits. The sheet says "An Application for Permit is to be filled out and submitted to the Building Division," the roofer "must provide a copy of their Illinois State Roofing License and a letter of intent on their letterhead stating they are replacing the roof at the specific address," and the "Permit fee is paid and the permit can be issued over the counter." It lists a "Roofing Permit Fee: $75.00 to be paid when the permit is issued" and a $75.00 re-inspection fee. An owner may roof a home only "if he/she is the occupant and it is a residential home." A designated landmark or a property in the Geneva Historic District needs Historic Preservation Commission review before the permit issues, and the sheet says "Mill Creek properties are not under the jurisdiction of the City of Geneva." Among its general comments the sheet says "Installation shall be per the 2021 IRC requirements and manufacturer's installation instructions," "Minimum of 2/12 pitch for asphalt shingles," "Double layer of underlayment required if pitch is from 2/12 to 4/12," and "Building wind speed design is at 90-MPH. 2021 IRC Table R905.2.4.1." The Permits page says "The City of Geneva does not have contractor registration.".

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 Permits page says "The City of Geneva does not have contractor registration."
Adopted code
THE 2021 INTERNATIONAL RESIDENTIAL CODE WITH CITY AMENDMENTS, PER THE CITY'S OWN CODES PAGE. The Building & Zoning Division's Codes & Documents page, under "Current Adopted Building Codes," lists "International Residential Code 2021 (with amendments)" and "International Energy Conservation Code 2024 (with State amendments)," and says "Residents and contractors can find more information on the amendments in the City's municipal code." The Roof Replacement Permit Information sheet lists "2021 Int'l Residential Code w/amendments" among "the Building Codes the City of Geneva has adopted." The amendments sit in Title 10 of the City Code, City of Geneva Building Regulations, which this record did not read, so it does not state whether the City has amended the IRC's roof provisions.
Ice & water shield
Required — REQUIRED, IN THE CITY'S OWN WRITTEN SHEET. The Roof Replacement Permit Information sheet says "Ice and Water Shield (residential) protection is required per the 2021 International Residential Code (R905.1.2)," and its notes add that "ANY ROOF WITH A" 6-inch "OR MORE OVERHANG AND OR A PITCH GREATER THAN 7/12 WILL REQUIRE MORE THAN" 36 inches "OF ICE AND WATER SHIELD." This rests on the department's own written sheet; the City's enacted amendments in Title 10 were not read. About ice & water barrier
Mid-roof inspection
Not required — ONLY A FINAL INSPECTION IS LISTED, PER THE CITY'S OWN SHEET. The Roof Replacement Permit Information sheet's list of "inspections that may be required for your project" names only the "Final Inspection," which it says "is conducted from ground level," and adds "If there are items that may not be visible, installation photos may be requested." This rests on the department's own written sheet; the City's enacted amendments in Title 10 were not read.
Roof layer limit / recover
The City's Roof Replacement Permit Information sheet says "Section R908.3.1.1 requires replacement of existing roof with two (2) layers," so a roof that already carries two layers must be torn off rather than covered again. This rests on the department's own written sheet; the City's enacted amendments in Title 10 were not read.
Sales & use tax
Illinois taxes the roofer, not the job, and the operative rate is not keyed to the Geneva 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.
