What this means for new work in Corpus Christi

Inside TWIA territory. Corpus Christi (Nueces County) is one of the 14 first-tier coastal counties covered by the Texas Windstorm Insurance Association per Texas Insurance Code Chapter 2210. Any new roofing, window, or exterior door install needs a WPI-8 Certificate of Compliance from a TDI-approved inspector to keep windstorm policy coverage active. Skip the WPI-8 and the next windstorm claim gets denied.

Direct Gulf salt-air exposure year-round. Use stainless or hot-dip galvanized for ALL exterior fasteners, AC condenser pads, garage door springs, and exterior steel framing. Mill-finish steel turns to rust in 12-18 months here.

Hurricane evacuation Tier A. Corpus Christi is in a mandatory evacuation zone per Texas DEM. Construction scheduled between June 1 and November 30 should include a clear storm-hold plan in the contract — installations halfway done when an evacuation order drops are the most expensive ones.
