To ensure your property remains eligible for TWIA coverage, you will need to obtain any needed Windstorm Certificates of Compliance, also known as WPI-8s or WPI-8-Cs. The Texas Department of Insurance (TDI) oversees the Windstorm Certification program and certifies ongoing repairs/improvements (WPI-8). TWIA certifies completed improvements (WPI-8-C).

To find out if your repairs/improvements require an inspection for either a WPI-8 or a WPI-8-C, call TDI before work begins at (800) 248-6032. Not all repairs require an inspection; you can consult TDI’s website,, or call to determine if the repair/improvement, whether completed or ongoing, requires an inspection.

To have TWIA issue a WPI-8-C for completed improvements, contact a Texas-licensed engineer to inspect your property. If the engineer confirms the repairs/improvements comply with the local building code requirements, they submit a form attesting to this.

TWIA will do everything possible to work with policyholders who have property damage from Hurricane Harvey, and will make reasonable accommodations to provide continuous coverage while the covered structure is undergoing repairs and inspection. However, without a WPI-8 or WPI-8-C, the structure may be considered ineligible for coverage with TWIA.
