Roof Replacement · St. Tammany County, Louisiana
Permit required
In Louisiana, 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 St. Tammany Parish Government- Permits & Inspections before work begins.

With a growing population of around 272,421 residents, St. Tammany County maintains a relatively streamlined permitting process compared to major urban hubs. Processing typically takes 1 to 3 weeks.
Code Compliance & Inspections
Because Louisiana sits in a hurricane-prone zone, the Louisiana Uniform Construction Code requires exterior work to use wind-rated materials and proper anchoring (such as tie-downs and impact-rated components) to pass inspection.
Technical Requirement: The St. Tammany County inspector will verify that the roof meets Wind Uplift Resistance standards and will inspect the nailing pattern before final shingles are placed.
Concurrent Permits & HOAs
For St. Tammany County residents, we highly recommend reviewing your neighborhood HOA covenants before paying any municipal fees. Often, homeowners associations maintain stricter rules regarding materials and dimensions for your Roof Replacement than the county itself.
