Windstorm inspection (WPI-8) in La Porte

Start with the address, not just ZIP 77571

Parts of La Porte are in Harris County’s designated windstorm area. TDI says a Harris County property must be east of Highway 146 and inside the boundaries of a city shown on its catastrophe-area map. A ZIP code alone does not establish whether a home falls within that area.

Check the exact address using TDI’s building-code and designated-area guidance. Ask your insurance agent which requirements apply to your home and planned work.

Why roof replacement brings this up

In the designated area, TDI says most roof replacements, major repairs and new construction need a windstorm inspection and a compliance certificate for TWIA coverage. Not every small repair needs certification. One listed exception is a repair under 100 square feet that does not involve roof decking; confirm the scope with TDI before relying on an exception.

A windstorm certificate addresses construction compliance. It does not guarantee an insurance policy or payment of a claim. TWIA has other eligibility requirements, and your insurance agent can explain how they apply.

WPI-8 and WPI-8-E cover different stages

WPI-8: TDI’s certificate for new or ongoing work. Arrange the inspection process before construction so the inspector can check the required stages.

WPI-8-E: TDI’s certificate for completed work. If a roof has already been replaced without the needed inspections, ask TDI about the completed-construction route and an appropriately licensed engineer. Do not assume an existing certificate covers later roof work.

WPI-8-C: an older TWIA certificate for completed work. TWIA accepted applications for these certificates from January 1, 2017, through May 31, 2020. Its historical lookup is separate from TDI’s database.

Questions to settle before signing a roof contract

• Is this address in the designated windstorm area, and does this exact scope need certification?
• Who will coordinate with the TDI inspector or appointed engineer, and when must each inspection happen?
• Who handles the application, required documents and certificate delivery?
• Does the written price include inspection or engineering charges? Ask the provider to identify any separate costs.
• Who addresses any findings before the roofing work is closed out?

Keep the written answers with your estimate. If a contractor says certification is unnecessary, confirm that answer with TDI and your insurance agent before authorizing the work.

Save the record and verify the next step

Use the official certificate searches linked by TWIA to look for existing records. Review the address, project description and date with your insurer; a record for one improvement is not proof that a different project was certified.

Ask the City separately about the permit and municipal inspection requirements for your scope. A city permit and a windstorm certificate answer different questions. For a completed job with missing paperwork, bring your contract and project records to TDI or the engineer reviewing the work.
