Windstorm-certified roofing (WPI-8)
Windstorm-certified roofing is roof work built to the Texas windstorm building code and inspected under the Texas Department of Insurance program, which issues a WPI-8 certificate of compliance. In TWIA's coverage area — including Jefferson and Chambers counties — you generally need that certificate to buy or renew TWIA windstorm coverage on the new roof.
- Typical time
- Adds inspection scheduling to a normal re-roof.
- Repair or replace
- Applies to new roofs and major repairs.
The Texas Windstorm Insurance Association (TWIA) insures wind and hail in 14 first-tier coastal counties, including Jefferson (Beaumont, Port Arthur, Nederland, Port Neches, Groves) and Chambers (Winnie, Anahuac). Orange and Hardin counties are not in TWIA's first-tier area, but building the same way still makes sense.
The process starts before the tear-off: the contractor or an engineer notifies TDI, inspections happen at specific stages such as decking nailing and final, and the certificate is issued after the work passes. Skipping an inspection can mean the roof can't be certified.

Windstorm-Certified Roofing (WPI-8): common questions
Does Orange County require windstorm certification?
Orange County isn't in TWIA's first-tier coastal area, so TWIA certification isn't required there. Local building codes still apply, and building to high-wind standards is still wise.
Can I get a WPI-8 after the roof is finished?
Only in limited cases through an engineer's post-construction evaluation, which may require opening areas. Plan inspections before the job starts.
