Service overview
WPI-8 Windstorm Certification Explained
The WPI-8 is the Texas Department of Insurance (TDI) certificate of compliance for windstorm code. It certifies that a new roof or re-roof in the catastrophe area was built and inspected to the windstorm construction requirements that apply there. The catastrophe area covers the first-tier Texas coastal counties, 14 in total, including Nueces, Aransas, San Patricio and Kleberg counties around Corpus Christi.
Why it matters is simple: without a WPI-8 on file, a wind claim can be denied, TWIA windstorm coverage can be unavailable, and a home sale or refinance can stall when the buyer's lender or carrier asks for it. The certificate is therefore not paperwork for its own sake. It is the document that connects a well-built roof to the insurance that protects it, and re-roofs here are built and documented so that the inspection process can be completed properly.

The service timeline
How the WPI-8 Process Works
The process flexes to the condition, but these checkpoints keep decisions clear.
Windstorm-Code Build
The re-roof is built to TDI windstorm requirements: deck re-nailed to code, correct fastening, sealed edges and system installation throughout.
Inspection Request
An inspection is requested through the TDI windstorm inspection process, with the build documentation assembled for the inspector.
On-Site Inspection
The inspector verifies the build against windstorm requirements, including fastening, detailing and system installation.
Certificate Issuance
Where the build passes, the TDI process issues the WPI-8 certificate of compliance for the roof.
Filing and Handover
The certificate and the supporting packet are filed and handed to you, ready for TWIA, your carrier, a buyer or a lender.

Use cases
When WPI-8 Documentation Matters
These examples show how the service framework adapts rather than forcing every call through one repair.
Typical Island Re-Roof
An island home re-roofed years ago without documentation, now facing carrier questions. → A new code-compliant re-roof documented by layer, with inspection completed and certificate filed.
Typical Sale-Ready Re-Roof
A sale stalled because the buyer's lender could not verify windstorm compliance. → A documented re-roof with certificate on file, removing the lender's objection entirely.

Questions before we arrive
Frequently Asked Questions
What is a WPI-8 certificate?
The WPI-8 is the Texas Department of Insurance certificate of compliance for windstorm code. It certifies that a new roof or re-roof in the catastrophe area was built and inspected to windstorm construction requirements.
Do I need a WPI-8 for my roof in Corpus Christi?
If your home is in the catastrophe area, which includes Nueces, Aransas, San Patricio and Kleberg counties, a new roof or re-roof needs a WPI-8 to stay eligible for TWIA windstorm coverage. Repairs that are not re-roofs do not trigger the same requirement.
What happens if there is no WPI-8 on file?
A wind claim can be denied, TWIA windstorm coverage can be unavailable, and a home sale or refinance can stall when a lender or carrier asks for windstorm documentation. The certificate connects a well-built roof to the coverage that protects it.
How is a re-roof documented for WPI-8 inspection?
The re-roof is built to windstorm code, each layer is photographed as work proceeds, material records are kept, and inspection is coordinated through the TDI process. The issued certificate and packet are then filed and handed to you.
