What TWIA Insurance Costs and What It Covers

Texas coast · Wind and hail only

TWIA is the residual market for wind and hail in eligible coastal territories. It does not cover flood, and this page will not quote a premium or a rate-change percent.

A residual market writes risks the private companies are not taking. On parts of the coast the homeowners or dwelling policy excludes wind and hail, and TWIA carries that piece. The other perils stay on the policy you buy for the house. Canceling one before the other is bound is a lapse. The dwelling limit is still a rebuild cost, not the sale price, and land is not insured. A wind or hail deductible is often a percent of that limit. Two percent of $450,000 is $9,000. That is an example, not a TWIA filing. When rebuild cost rises, the dollar deductible rises with it. A new roof does not shrink the percent. Wind that opens the house, then rain through that opening, is the wind claim. Water that comes in over the ground, including storm surge, is flood. A hurricane name does not move that water onto TWIA.

A WPI-8 is a windstorm inspection certificate. It is not flood coverage and not a guaranteed percent off. It documents that the construction met the inspection. Eligibility and any credit are whatever the current rules say. The price moves with the limit, the deductible, the territory, and the cost of the residual market. Those are reasons a renewal can change. They are not a number to copy from a blog. Current rules and forms are on TWIA’s own site. A private coastal policy, if a carrier will write the wind, is a different contract.

The rate headline, without a made-up percent: a premium change is not a blog number. The season is not the coverage: hurricane season. Hail on a house that is not in this market: hail. The water TWIA leaves out: flood. The certificate: what a WPI-8 is. The policy that still has to exist for the other perils: Texas homeowners, what it covers, and coverage. The product page: Texas homeowners insurance.

Read whether wind is on your policy or on TWIA, and buy flood separately if you want that water covered. Ask an agent or start a home quote.
