Do I need a permit for roof replacement or repair in Marietta?

Most likely yes. Roof replacement or repair usually requires a permit in Georgia. Confirm the specifics with Marietta.

Reroofing generally requires a building permit in Georgia jurisdictions; confirm your city or county threshold and whether a state-licensed roofer is required. Structural sheathing or decking replacement can add a separate inspection, so tell the inspector if you expose the deck. Cobb County's own permitting office is the Cobb County Development and Inspections, reachable on 770-528-1000 at https://www.cobbcounty.gov/community-development/building-development/permitting. Its online permit portal is https://cobbca.cobbcounty.gov/CitizenAccess/default.aspx. It issues permits for the unincorporated county. If your city does not run its own building department, and many smaller Georgia municipalities do not, this is the office that will handle the job. Roofing permits and the dry-in inspection are handled by whichever office serves your address, so confirm that before the tear-off starts. Marietta requires a permit whenever an owner or contractor intends to alter or repair a building, and its homeowner page lists only painting, flooring, and fencing as not needing a permit. The city publishes no separate re-roofing exemption. In one of Marietta's locally designated historic districts, exterior changes go through a Certificate of Appropriateness from the Historic Preservation Commission (Article 7-8-9), or the Historic Board of Review for the Downtown district (Article 7-8-8). City of Marietta addresses (Cobb tax district 4, MARIETTA) are permitted and inspected by the City of Marietta Building Inspections office at 205 Lawrence Street, 770-794-5659. Addresses in tax district 9, UNINCORPORATED, go to Cobb County instead.
