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

Code Compliance & Inspections
Because of severe winter weather in Massachusetts, any exterior structures or footings must be set below the local frost line to prevent shifting, as mandated by the Massachusetts State Building Code.
Technical Requirement: It is mandatory to install Ice and Water Shields on the roof eaves to prevent leaks from ice dams during Massachusetts winters.
