Do I need a permit for roof replacement or repair in Naperville?
It depends. Whether roof replacement or repair needs a permit in Naperville comes down to the details of your project.
For a single-family home, Naperville does not require a permit to install an asphalt composite shingle roof as long as the existing roof sheathing stays in place. A permit IS required if you replace the roof sheathing, remove EIFS, or install another roofing material such as metal, wood, slate, or a sealed membrane, so many re-roofs beyond a like-for-like shingle overlay do need a permit. Even when no permit is required, the property owner is still responsible for meeting the City-adopted building codes, and Naperville advises that any roofer hired must be licensed by the State of Illinois. Naperville adopts and amends the ICC family of codes (the 2024 International Residential Code takes effect April 1, 2026). Confirm current requirements with the TED Business Group at (630) 420-6100, Option 2, before starting, and check your homeowners association rules. Most Illinois jurisdictions require a permit for roof replacement even when the new material is a similar weight, while like-for-like repairs of small areas may be exempt. Many local codes limit the number of roof covering layers and require an ice barrier and underlayment. Which residential code edition sets those details is decided by your municipality or county, because Illinois has no statewide residential code governing work on an existing home.
