Do I need a permit for roof replacement or repair in Downers Grove?
Yes. In Illinois, roof replacement or repair generally requires a permit, and Downers Grove is no exception.
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. The Village of Downers Grove requires a permit for residential re-roofing and publishes a Residential Re-Roofing Requirements document that must be followed. Confirm current tear-off and ice-barrier details with Community Development. Roofing work in Illinois must be performed by a contractor holding a state roofing license (IDFPR). Verify the contractor is registered and bonded with the Village before work begins.
