Do I need a permit for roof replacement or repair in Knoxville?
Yes. In Tennessee, roof replacement or repair generally requires a permit, and Knoxville is no exception.
A building permit is generally required to replace a roof covering even when the structure is unchanged; local departments such as Metro Nashville and Knox County require and inspect reroof permits. Do not confuse the $25,000 contractor-licensing threshold under TCA 62-6 with a permit exemption; there is no statewide dollar-value permit exemption, so a permit is still required regardless of job cost. Knoxville Plans Review and Inspections issues roofing permits inside the city limits through the permits.knoxvilletn.gov portal; property in unincorporated Knox County is handled by Knox County Codes Administration instead, so confirm you are inside the city. Knoxville enforces the adopted International Residential Code and its own municipal building codes; the city notes only a limited overlay of a second layer of shingles over an intact first layer is allowed, so verify your scope before assuming an overlay is permitted. Tennessee requires a state contractor license for residential building work above roughly 25,000 dollars (the city references a 24,999.99 dollar threshold for single-family work intended for resale, lease, or rent), so confirm licensing before hiring.
