The Texas Windstorm Insurance Association (TWIA) is the insurer of last resort for wind and hail coverage in Texas's coastal counties. It exists because private insurers largely refuse to offer windstorm coverage in areas exposed to Gulf hurricane risk — leaving coastal homeowners with no market alternative.
Understanding TWIA — what it covers, how it works, how claims are filed, and especially how to handle the wind-versus-flood dispute that defines every major Gulf Coast hurricane claim — is essential for any homeowner in the 14 eligible coastal counties. This guide covers everything.
1. What Is TWIA and Why Does It Exist?
TWIA (Texas Windstorm Insurance Association) was created by the Texas Legislature in 1971 after Hurricane Celia devastated Corpus Christi and private insurers began withdrawing wind coverage from coastal Texas. It is a state-created insurer of last resort — not a government agency, but an association of all insurers doing business in Texas who are required to participate.
TWIA provides coverage for wind and hail damage specifically. It does not cover:
- Flood or storm surge damage (covered by NFIP)
- Fire, theft, or liability (covered by your homeowners policy)
- Personal property (unless added via endorsement)
⚠️ The Coverage Gap Most Coastal Homeowners Don't Know About
After Hurricane Harvey (2017), thousands of Texas homeowners discovered they had a homeowners policy and flood insurance — but no TWIA windstorm policy. Their wind damage claims were denied because their homeowners policy excluded wind in TWIA-eligible counties. Check your declarations page right now to confirm you have all three layers of coverage where applicable.
2. Which Texas Counties Require TWIA Coverage
TWIA coverage is available (and standard homeowners policies typically exclude wind) in 14 coastal counties and parts of Harris County:
If your home is in one of these counties and you don't have a separate TWIA policy, contact your agent immediately. You cannot obtain TWIA coverage after a storm has been named or a watch has been issued for your area.
3. What TWIA Covers
A standard TWIA windstorm policy covers:
- Dwelling coverage — the structure of your home, including roof, walls, windows, and attached structures
- Other structures — detached garages, fences, outbuildings (subject to limits)
- Personal property — if you add the contents coverage endorsement (not included by default)
- Additional living expenses (ALE) — if the home becomes uninhabitable due to covered wind damage
Coverage limits vary. The maximum TWIA dwelling coverage limit is $1.77 million for residential properties. If your home's replacement cost exceeds this, you'll need a separate excess windstorm policy through the private market.
4. TWIA Deductibles: What You'll Pay Out of Pocket
TWIA policies have two deductibles:
Standard Deductible
Applies to non-hurricane wind and hail events. Typically a flat dollar amount ($500–$2,500) or 1% of insured value. This is the deductible for hail damage or wind damage from a regular storm (not a named hurricane).
Hurricane Deductible
Applies when damage occurs during a named hurricane. Typically 2–5% of the insured dwelling value. On a $350,000 home: that's $7,000–$17,500 out of pocket before TWIA pays anything. This deductible triggers automatically when the National Hurricane Center issues a hurricane watch or warning for your county.
5. The Wind-vs-Flood Problem: The Most Contested Issue in Gulf Coast Claims
After a hurricane, your home may suffer both wind damage (TWIA) and flood damage (NFIP flood insurance). These are covered by two different policies, two different insurers, and subject to two different claims processes. Both insurers have financial incentive to attribute damage to the other's policy.
This is called the wind-versus-flood dispute, and it was the defining controversy of Hurricane Harvey (2017), Hurricane Ike (2008), and Hurricane Rita (2005). The legal and financial battles from these disputes lasted years in Texas courts.
How it plays out in practice:
- TWIA adjuster: "The interior damage was caused by rising floodwater, not wind. We cover only the exterior roof and structural damage from wind."
- NFIP adjuster: "The water intrusion came through the storm-damaged roof opening, not from ground flooding. That's a wind claim."
- Result: Both deny significant portions of the claim. The homeowner is caught in the middle.
How to Protect Yourself: Documentation Strategy
- Before the storm: Photograph the entire exterior and interior. Document the current condition of your roof, windows, doors, and foundation.
- During the storm (if safe): Note the time sequence — when wind damage occurred vs. when water appeared.
- Immediately after: Photograph watermarks on walls (showing maximum flood height), debris patterns, and where wind vs. water damage stops. Time-stamp everything.
- Before anything is cleaned: Have a licensed contractor inspect and write separate reports for wind damage and water intrusion sources.
- File both claims simultaneously — don't wait for one insurer's determination before filing with the other.
6. How to File a TWIA Claim
- File immediately after damage: Call TWIA at 1-800-788-8247 or file online at twia.org. Document the exact date and time of filing.
- Make temporary repairs to prevent further damage: Tarp your roof, board windows. Keep all receipts — TWIA reimburses reasonable emergency repair costs.
- Get an independent contractor inspection first: Before TWIA's adjuster visits, have a licensed TDLR contractor inspect and document all damage in writing. This gives you a comparison baseline.
- Cooperate with TWIA's adjuster — but document everything: Be present during the inspection. Take your own photos. Note what the adjuster does and doesn't look at.
- Review the estimate carefully: If the adjuster's estimate doesn't match your contractor's assessment, don't immediately accept it. You have options.
7. If You Disagree With Your TWIA Settlement
TWIA claims disputes follow specific procedures under Texas law:
- Request a re-inspection: Submit additional documentation from your contractor and formally request TWIA reconsider. Do this in writing.
- Invoke the appraisal process: Your TWIA policy includes an appraisal clause — each party selects an appraiser and they agree on an umpire to resolve disputes. This is a formal process but often faster than litigation.
- File a TDI complaint: The Texas Department of Insurance regulates TWIA. File a complaint at tdi.texas.gov or call 1-800-252-3439.
- Consult a public adjuster: A licensed public adjuster can review your settlement, document additional damage, and negotiate with TWIA on your behalf. They work on contingency (a percentage of any additional settlement).
