Do I need a permit for roof replacement or repair in Unincorporated Will County?
Yes. In Illinois, roof replacement or repair generally requires a permit, and Unincorporated Will County is no exception.
In Will County, permits outside the cities are handled by the Will County Land Use Department, Building Division, reachable on 815-727-8634 at https://willcounty.gov/County-Offices/Economic-Development/Will-County-Land-Use-Department. Its online permit portal is https://co-will-il.smartgovcommunity.com/Public/Home. This office permits the unincorporated parts of Will County. If your address sits inside a municipality, that municipality issues the permit instead. Roofing permits and the dry-in inspection are handled by whichever office serves your address, so confirm that before the tear-off starts. 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.
