The Windstorm Inspection Program operated by the Texas Department of Insurance mandates that, in the 14 coastal catastrophe area counties, which include Cameron County, homeowners must provide proof that any construction or substantial renovations complied with the windstorm building code standards. This is shown on what the industry usually refers to as a WPI-8 certificate, if the Texas Windstorm Insurance Association is to cover the property at all. The state also enacted House Bill 1774 in 2017. It is a major reform of how it manages residential property claims, following a surge in hail-damage litigation. This legislation altered both the notice requirements before filing a lawsuit and how insurers can arrange agreements with contractors who carry out repairs after a storm. The Law Offices of Ignacio Martinez reviews claim denials across Brownsville and the Rio Grande Valley. Most of these denials stem from a small set of recurring issues.

Wind-Driven Rain vs. Flood: The Causation Dispute That Kills Coastal Claims
Homeowners insurance and TWIA policies typically cover wind-driven rain that enters through storm-caused openings such as roof damage or debris-broken windows. They do not cover flood, which describes water that rises around the exterior of the building regardless of what causes the water level to rise. When insurers are looking into a loss caused by a coastal storm. They often claim that the water damage was actually due to floodwater that had risen, rather than wind-driven rain. Classifying the loss as a flood case shifts the responsibility to the homeowner’s individual NFIP policy. If the homeowner never had flood insurance, there would be no coverage at all. Pictures and videos captured during the storm that show water entering through a wind-caused opening rather than rising from the ground. They serve as far stronger proof of wind-driven rain damage. Photographs taken days later carry less weight. By then water has spread and mixed throughout the home, so the source can no longer be clearly shown.
This dispute over cause is responsible for more denied or reduced coastal claims than almost any other issue we encounter, simply because after the water recedes, wind and flood damage can look very similar.
Late Notice: How “Prompt” Actually Gets Interpreted
Most policies require the insured to notify the insurance company of a loss as soon as possible, without specifying an exact number of days.
Anti-Concurrent-Causation Clauses and Multiple Contributing Causes
Many property insurance policies include an anti-concurrent-causation clause. This clause states that when an excluded hazard such as flood contributes to a loss at the same time as a covered hazard such as wind. The insurer may deny the entire claim instead of paying only for the portion caused by the covered peril. This type of clause has become a significant source of legal disputes across the country following major coastal hurricanes that caused combined wind and flood damage to the same houses. Texas courts have considered how far an insurer can go in interpreting this clause in order to reject a valid wind claim simply because flooding took place nearby or afterward. This clause may help or harm your claim depending on exact policy language and the specific sequence of events during the storm. Review the actual policy text whenever you receive a denial based on concurrent causes. Do not simply accept the summary provided in the denial letter.
Before agreeing that a denial based on multiple causes is valid under Texas law, we look at the specific anti-concurrent-causation provisions in the client’s policy.
Assignment of Benefits Disputes With Contractors
Common Denial Reasons at a Glance
| Common Denial Reason | What It Actually Means | How to Reduce the Risk |
|---|---|---|
| Missing or outdated WPI-8 certificate | TWIA disputes the property was ever properly certified for windstorm coverage | Confirm WPI-8 status with TDI before storm season |
| Vacancy clause | Policy suspends or limits coverage after a set period of vacancy | Document occupancy checks during extended absences |
| Wind vs. flood causation dispute | Insurer reclassifies covered wind damage as excluded flood damage | Photograph water entry points during the storm itself |
| Late notice | Insurer argues delayed reporting harmed its ability to investigate | Report the loss within days, even with incomplete details |
| Anti-concurrent-causation clause | Insurer denies the whole claim citing a contributing excluded peril | Have the specific policy clause reviewed against the facts |
| Disputed assignment of benefits | Insurer challenges the validity of a contractor assignment agreement | Review any AOB carefully before signing |
Checklist: Reducing Denial Risk Before You File
- Confirm your property’s WPI-8 windstorm certificate status with TDI before storm season, not after a claim
- Arrange documented occupancy checks if the property sits vacant for extended periods
- Photograph and video water entry points during the storm itself, not just the aftermath
- Report any loss within days of the storm, even before you know the full extent of the damage
- Read the anti-concurrent-causation language in your policy before assuming a multi-cause denial is final
- Review any assignment of benefits agreement carefully before signing it over to a contractor
- Keep a copy of your full policy, not just the declarations page so that you can check exclusions yourself
How We Help When a Claim Gets Denied
As soon as a client gives a denial letter, our first step is to find the exact policy language that matches the reason the insurance company gave. Denial letters often summarize a clause in a way that makes it seem wider than it is in the policy. We then check whether the reason for the denial reflects a true gap. For example, the absence of a WPI-8 certificate—or whether it stretches a clause, such as the anti-concurrent-causation rule, beyond what Texas law permits insurers to do. If the denial doesn’t stand up, we send the official notice required by Texas law before taking legal action and then negotiate from there. But if it does, we tell the client directly rather than pursuing a claim that cannot succeed. The denial letter represents the insurer’s position only. It is not the final determination of what the client is actually entitled to. We help clients work out this distinction.
Regarding the use of this article: the following is general information concerning the typical reasons for denials in Brownsville and Cameron County. It should not be regarded as legal advice about your particular denial letter or policy. The language in insurance policies varies greatly among different carriers. They can also differ between policy years offered by the same carrier. Texas insurance laws change from time to time. You should consult a licensed Texas attorney before making any assumptions as to whether the general patterns described here apply to your individual claim. It is recommended before reviewing your actual policy and denial letter with them.
Facing an Unfair Insurance Claim Denial on Your Home?
Insurers frequently deny residential claims citing wear and tear, late filing, or complex exclusions like anti-concurrent causation. Before accepting a partial payout or full denial, have your policy language and structural evidence independently evaluated to uncover errors in the carrier’s assessment.

Frequently Asked Questions
Can an insurance company refuse my claim simply because I have made previous claims?
What is considered to be a “material misrepresentation,” and would a minor error on my application result in the entire policy being cancelled?
Must I accept the denial, or is it possible for me to appeal directly to the insurer before taking any further action?
Can my insurance company refuse to pay out because of a separate code violation, for example, if a smoke detector is missing?
Normally, an insurer cannot reject an entire claim for storm damage simply because of an unrelated code violation that has nothing to do with causing the loss. The violation and the storm damage are separate matters. The situation becomes more complicated, however, when the code violation actually contributes to the damage itself. For example, when faulty wiring leads to a fire during a power surge caused by the storm. Insurers may at times refuse to cover damage that their investigation links directly to a maintenance or code issue rather than the storm. Insurers may also cite unrelated violations as a reason for not renewing a policy or for adjusting future premiums. This is a different consequence from denying the specific claim at hand. When a denial letter mentions a code violation, the key question is whether the violation relates to how the damage occurred, not merely whether it exists.
