Roof Replacement · Gallatin County, Kentucky
Permit required
In Kentucky, a Roof Replacement requires a building permit.
Replacing a roof requires a building permit in virtually every jurisdiction (IRC R907). Minor repairs under roughly one square (about 100 sq ft), like patching a leak or swapping a few shingles, are usually exempt. A roof with three or more existing layers must be torn off to the deck before re-roofing (IRC R907.4). Plans are reviewed under the Statewide (local may vary) code (IRC 2015); apply through Gallatin Codes & Building Permits before work begins.
