What this means for new work in Calallen

Inside TWIA territory. Calallen (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.

Near-coastal salt-air on east winds. Galvanized fasteners and primer-coated exterior steel last years longer than mill-finish โ€” the salt reaches this far inland on most east-wind days.

Hurricane evacuation Tier C. Calallen is on the formal evacuation list โ€” last to evacuate, but on the list. August-October projects should plan for a possible 24-48 hour weather hold per major Gulf storm.
