Do you need a permit for Roof Replacement in San Patricio County?
In Texas, a Roof Replacement requires a building permit.
San Patricio is one of the 14 Texas coastal catastrophe-area counties, so a re-roof must meet the Texas Department of Insurance (TDI) windstorm standard and be inspected and certified with a WPI-8 (applied for before work begins). Roofing materials must be TDI-evaluated and wind-rated (ASTM D3161 or better), with a secondary water barrier and enhanced fastening. The WPI-8 keeps the home eligible for windstorm and hail (TWIA) insurance, and a city building permit may also apply. Plans are reviewed under the San Patricio County, TX (TDI windstorm / WPI-8) code (IRC 2018 IRC (TDI)); apply through Portland City Building Permits before work begins.
