Do you need a permit for Roof Replacement in Defiance County?
In Ohio, 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 2018); apply through Defiance Building Inspection before work begins.

Technical Requirement: It is mandatory to install Ice and Water Shields on the roof eaves to prevent leaks from ice dams during Ohio winters.
