Do I need a permit for roof replacement or repair in Joliet?
Yes. In Illinois, roof replacement or repair generally requires a permit, and Joliet is no exception.
Joliet requires a permit for all roofing work and will only permit full slope replacements. Per Ordinance 7456 and the City's Roof Repair Policy, the City does not permit patching of shingles, which it defines as any number of shingle replacements on a slope that would mix new and remaining shingles. Under the adopted 2015 International Building and Residential Codes, solid sheathing is required, underlayment must be an approved type, and ice and water shield must be installed along eave edges and in valleys. A roof cannot be recovered if the existing roof is water soaked, deteriorated, or already has two or more coverings. If a contractor performs the work, the contractor must pull the permit (Sec. 8-36 of the Code of Ordinances) and be registered with the City. Apply by emailing forms to permitapplication@joliet.gov or the City Hall drop box, with roofing permits estimated around 10 business days. 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.
