Do you need a permit for Roof Replacement in Rockingham County?
In New Hampshire, 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 code (IRC 2021); apply through Salem Building Department before work begins.
