Key takeaways

  • Standard homeowners policies on the Texas coast exclude wind and hail. That damage has to be covered somewhere else — or it isn't covered at all.
  • You have three routes to wind coverage: TWIA, a private windstorm policy, or a home policy with windstorm already included.
  • A windstorm-included home policy collapses two policies into one — one carrier, one deductible structure, one adjuster after a storm.
  • Windstorm deductibles are a percentage of your dwelling limit, not a flat dollar amount. Most homeowners have never calculated theirs.
  • Flood is always separate. No wind policy and no home policy covers storm surge or rising water.
  • Timing is coverage. New flood policies carry a 30-day wait, and windstorm binding suspends once a named storm enters the Gulf.

Why wind and storms get split up on the coast

Every homeowner in Texas City, Galveston, La Marque, Dickinson and the rest of the coast eventually learns the same lesson, and most learn it the expensive way: a hurricane is not one insurance event. It is three or four, split across separate policies, each with its own deductible, its own carrier, and its own adjuster.


Fifty miles inland, one homeowners policy absorbs nearly everything a storm can do. Down here, it does not. Carriers writing coastal property have excluded wind and hail for decades because of hurricane exposure, which means the single most likely source of damage to your home is carved out of the policy you assume protects it.



That is the gap this article is about — and the good news is that the old three-policy scramble is no longer your only option.

What wind and storms actually damage, and who pays for it

Before comparing your options, it helps to see how a single hurricane gets divided up:

Type of damage Which policy pays Typical deductible
Wind and hail TWIA, a private windstorm policy, or a windstorm-included home policy Percentage of dwelling limit, usually 1%–5%
Storm surge, rising water, flooding from rainfall NFIP or private flood policy Flat dollar, commonly $1,000–$10,000
Fire, theft, liability, interior water damage Homeowners policy Flat dollar, often $1,000–$5,000
Rain through an opening the wind created Your wind coverage Wind deductible applies
Rain through an opening the wind did not create Usually nobody — commonly excluded N/A

Miss any one layer and you have an uninsured hurricane. That is the single most useful thing to understand about wind and storms on the Texas Gulf Coast.

Your three routes to windstorm coverage

1. TWIA — the residual market

The Texas Windstorm Insurance Association is a not-for-profit insurer of last resort. It provides wind and hail coverage to property owners who cannot get it in the private market, across the 14 first-tier coastal counties plus the portion of Harris County east of Highway 146.

To qualify, the property must sit in the designated catastrophe area, the applicant must have been declined by at least one authorized insurer, the structure must be certified to applicable building codes with limited exceptions, and flood insurance must be in force where it is required.

The catch: TWIA is wind and hail only. It is not a homeowners policy. Every TWIA policyholder needs a companion "wraparound" home policy that excludes wind — two policies, two carriers, two bills, and after a storm, two separate claims that can disagree about what caused what.


2. A private windstorm policy

Private carriers do write wind and hail on the Texas coast, and for many properties the terms compare favorably to the residual market — particularly newer homes and those with modern roof systems, impact-rated openings, or hurricane straps, which frequently earn construction credits that TWIA's rating structure does not reward the same way.


A private windstorm policy still sits alongside a separate wraparound home policy, so the two-policy structure remains. What changes is who you are insured with, how your claim gets handled, and often what you pay.


3. A windstorm-included home policy — one policy, wind covered

This is the option most coastal homeowners do not know exists, and it is the one we built this agency's practice around.


Instead of buying a home policy that excludes wind and then bolting a windstorm policy onto it, a windstorm-included home policy covers wind and hail inside the homeowners form itself. One carrier. One policy. One adjuster after the storm.


The practical difference shows up at claim time. In the two-policy structure, a wind claim and a non-wind claim can land with two different companies, and the homeowner ends up in the middle of a causation argument about which peril did which damage. With wind included on a single form, that argument largely disappears.


Eligibility and availability vary by property, construction, location and carrier appetite. [BRAD — insert your current eligibility notes here: which carriers, which counties, typical dwelling-limit range, roof-age requirements. Being specific here is what will make this section rank and convert.]

Comparing your three options side by side

TWIA + wraparound Private windstorm + wraparound Windstorm-included home policy
Number of policies Two Two One
Wind & hail covered Yes Yes Yes
Fire, theft, liability On the wraparound On the wraparound Same policy
Flood covered No — buy separately No — buy separately No — buy separately
Claims after a storm Two carriers, two adjusters Two carriers, two adjusters One carrier, one adjuster
WPI-8 required Yes, with limited exceptions Varies by carrier Varies by carrier
Credits for newer construction Limited Often available Often available
Best suited to Properties declined elsewhere Homes that qualify on construction Homeowners who want one policy and one claim

There is no universally correct answer here. The right structure depends on your property's construction, age, roof, location and certification status — which is exactly what a coverage review is for.

Percentage deductibles: the number most homeowners get wrong

Wind deductibles are not flat dollar amounts. They are a percentage of your Coverage A dwelling limit.


Worked example. A home insured for $400,000 with a 2% wind deductible carries an $8,000 out-of-pocket obligation before the policy responds. At 5%, that same home carries $20,000.


Two consequences follow:

  1. Deductible choice is your largest premium lever. Moving between tiers can swing a coastal wind premium substantially. That savings is real — but it is money you are agreeing to carry yourself at the worst possible moment.
  2. Your deductible grows when your dwelling limit does. Inflation-adjustment endorsements raise Coverage A automatically at renewal, which is correct and necessary. But your dollar deductible rises right along with it, quietly, without a phone call.


Ask yourself one question before choosing a tier: could I write that check within a week of a hurricane, when contractors are scarce and prices are climbing? If not, buy the lower deductible.

The WPI-8 certificate: the paperwork that stalls coastal applications

The WPI-8 is the windstorm building-code certification issued after an inspection confirms a structure meets applicable coastal building standards. Missing or outdated WPI-8 documentation is one of the most common reasons a coastal application stalls — and it becomes a serious problem when a homeowner tries to bind coverage in August.



If you have added a roof, replaced windows, or built an addition since your last certificate, your WPI-8 may no longer cover the whole structure. Our walks through what the certificate is, when you need a new one, and how to get one.

Flood is separate — no matter which route you choose

This is the largest and most expensive misunderstanding in coastal insurance, so it is worth stating plainly: none of the three options above cover flood. Not TWIA, not a private windstorm policy, not a windstorm-included home policy.


Wind damage is caused by air pressure and debris — a lifted roof, broken windows, downed trees. Flood damage is caused by water rising from the ground up, including storm surge. They are different perils on different policies with different deductibles, and the distinction determines who pays.



A meaningful share of NFIP claims come from properties outside high-risk mapped zones. Every property is in a flood zone; some are simply rated lower risk. If you are inland of the surge line and skipping flood coverage because of your zone designation, you are making a bet on the map rather than on the weather.

Timing is coverage: the deadlines that decide whether you are protected

  • Hurricane season runs June 1 through November 30. The Gulf's most active stretch is mid-August through October.
  • New NFIP flood policies carry a 30-day waiting period in most circumstances, with narrow exceptions such as a policy purchased in connection with a loan closing. A policy bought as a storm approaches will not respond to that storm.
  • Binding suspends when a named storm enters the Gulf. TWIA and private carriers stop writing new business and stop increasing limits once a system is in the box. Underwriting can freeze for a week or more.
  • Report claims promptly. TWIA generally requires notice of claim within one year of the date of loss, with separate, shorter deadlines for demanding appraisal or filing suit. Private carriers set their own.



The practical rule: make coverage decisions in the spring, not in the cone. By the time a storm has a name, your options are whatever you bought in April.

Your pre-season coverage review: seven checks

  1. Confirm the wind exclusion. Pull up your homeowners declarations page and search for the words windstorm, hail, or exclusion endorsement. If they are there, your wind coverage lives somewhere else — or nowhere.
  2. Verify your wind coverage is in force and that the named insured, mortgagee and mailing address are all current.
  3. Check Coverage A against today's rebuild cost — not market value, not your tax appraisal. Coastal labor and materials have moved sharply.
  4. Calculate your wind deductible in dollars. Multiply Coverage A by your percentage. Write the number down.
  5. Confirm replacement cost, not actual cash value, on both dwelling and contents. ACV settlement on a 15-year-old roof after a hurricane is a brutal surprise.
  6. Buy flood coverage even outside a mapped high-risk zone.
  7. Photograph everything now — roof, all four elevations, interior room by room, serial numbers on major items. Date-stamped pre-storm documentation is the strongest answer to a pre-existing damage argument.

Frequently asked questions

  • Does my homeowners insurance cover wind and storms in coastal Texas?

    Usually not. Homeowners policies written in the designated catastrophe area typically carry a windstorm and hail exclusion. Wind and hail damage is covered by TWIA, a private windstorm policy, or a home policy written with windstorm included.

  • What is a windstorm-included home policy?

    It is a homeowners policy that covers wind and hail inside the policy itself rather than excluding it. Instead of carrying a separate windstorm policy alongside a wraparound home policy, you have one policy, one carrier, and one adjuster after a storm.

  • Is private windstorm insurance better than TWIA?

    It depends on the property. Private carriers often give credit for newer construction, updated roofs and impact-rated openings, which can produce better pricing or terms. TWIA exists specifically for properties that cannot get coverage in the private market. The only way to know which is better for your home is to compare both.

  • What is the difference between wind damage and flood damage?

    Wind damage is caused by air pressure and debris — a lifted roof, broken windows, downed trees. Flood damage is caused by water rising from the ground up, including storm surge. They are covered by different policies with different deductibles.

  • Do I need flood insurance if I am not in a flood zone?

    Every property is in a flood zone; some are simply rated lower risk. Flood is excluded from every home and wind policy, so without a separate flood policy that damage is uninsured regardless of what the map says.

  • Can I buy windstorm insurance right before a hurricane?

    No. Carriers suspend binding once a named storm enters the Gulf, and new flood policies carry a 30-day waiting period. Coverage has to be in place well before a system forms.


  • How much is my windstorm deductible?

    Multiply your Coverage A dwelling limit by your deductible percentage. On a $400,000 dwelling limit with a 2% deductible, that is $8,000.


  • Do I need a WPI-8 certificate?

    For TWIA, yes, with limited exceptions. For private and windstorm-included policies, requirements vary by carrier. If you have replaced a roof or added on since your last certificate, it may need to be updated either way.


Have your coverage read before the next storm — not after

Most coastal claim disputes are not really claim disputes. They are policy-structure problems that were visible on the declarations page months earlier: a dwelling limit that never kept up with rebuild costs, an actual cash value settlement nobody flagged, a flood policy nobody bought, a WPI-8 that stopped matching the house three renovations ago.


We have been reading coastal policies from our Texas City office since 1986, three generations in. We will compare TWIA, private windstorm and windstorm-included options side by side for your specific property and show you what each one actually does at claim time.

Windstorm Claim Checklist: Smart Steps To Take Right Away

June 15, 2026
Windstorm damage can leave homeowners dealing with roof problems, broken windows, fallen debris, and urgent repair decisions all at once. For homeowners in Texas City, TX, knowing what to do immediately after a storm can make the claim process clearer, better documented, and less stressful. Start With Safety First After a windstorm , the first priority is safety. Before checking damage, make sure everyone in the household is accounted for and away from immediate hazards. Strong winds can leave behind loose power lines, unstable trees, damaged roofs, broken glass, and weakened structures. Do not climb onto the roof or enter areas that appear unsafe. Even if the damage looks manageable from the ground, hidden structural problems can make inspection dangerous. If you smell gas, see sparks, notice major structural movement, or suspect electrical damage, leave the area and contact the proper emergency service provider. In our work with clients, a common issue we see is that homeowners try to inspect or fix damage too quickly. It is understandable to want answers right away, but safety should come before documentation, repairs, or cleanup. Prevent Further Damage When Possible Most insurance policies require homeowners to take reasonable steps to prevent additional damage after a covered loss. This does not mean making permanent repairs immediately. It means taking practical temporary measures when it is safe to do so. Examples may include: Placing a tarp over a damaged roof area Boarding up a broken window Moving undamaged belongings away from water intrusion Covering exposed openings Drying wet areas when safe Turning off water if plumbing was affected Securing loose items that could cause more damage Keep receipts for materials, labor, emergency services, tarps, storage, or temporary repairs. These expenses may be considered during the claim, depending on the policy. Document The Damage Thoroughly Good documentation can make a major difference in a windstorm claim. Take photos and videos before making temporary repairs, if it is safe. Capture wide shots of the property and close-up images of specific damage. Focus on areas such as: Roof shingles, tiles, flashing, gutters, and vents Siding, trim, soffits, and fascia Windows, doors, screens, and shutters Fences, sheds, detached structures, and carports Interior ceiling stains or water intrusion Damaged personal property Fallen trees, limbs, or debris Outdoor equipment and furniture When possible, include date-stamped photos and notes describing what happened. If neighbors near Galveston Bay or Moses Lake experienced similar storm impact, that can provide useful context, but your claim should still focus on your own property damage. Review Your Insurance Policy Before filing or during the early claim process, review your policy carefully. Windstorm coverage can vary by carrier, property location, deductible type, and policy form. Pay close attention to: Whether windstorm or hail damage is included Whether you have a separate windstorm policy Your windstorm deductible Roof coverage terms Exclusions or limitations Other structures coverage Personal property coverage Loss of use coverage Claim reporting deadlines For homeowners in Texas City, TX, windstorm coverage deserves special attention because coastal exposure can affect how coverage is written. Some homeowners may have wind coverage through a separate policy rather than their standard homeowners policy. Understand Your Windstorm Deductible A windstorm deductible may work differently from a standard deductible. Some policies use a flat deductible, such as a set dollar amount. Others use a percentage deductible based on the insured value of the home. For example, if your home is insured for a certain amount and your wind deductible is a percentage, your out-of-pocket responsibility could be higher than expected. This is why it is important to review the deductible before a storm, not after damage occurs. A common misunderstanding is assuming the deductible will be the same for every type of claim. Fire, theft, water damage, hurricane, hail, and windstorm claims may have different deductible rules depending on the policy. Contact Your Insurance Agent Or Carrier Promptly Once the property is safe and you have initial documentation, contact your insurance agent or insurance company to report the damage. Provide clear details about the date of the storm, the type of damage, and any temporary steps taken to prevent further loss. Be prepared to provide: Policyholder name Policy number, if available Property address Date and approximate time of damage Description of visible damage Photos or videos Receipts for temporary repairs Contractor estimates, if available Ask what the next steps are and whether an adjuster will inspect the property. Also ask whether there are specific forms, deadlines, or documentation requirements. Avoid Permanent Repairs Too Soon Temporary repairs are usually encouraged when needed to prevent further damage. Permanent repairs should generally wait until the insurance company has had an opportunity to inspect the damage or provide claim guidance.  If emergency permanent work is unavoidable, document everything carefully. Take photos before, during, and after the work. Keep detailed invoices, contractor notes, and material receipts. Do not discard damaged materials until the adjuster has reviewed them or until you are told it is acceptable. If damaged items must be removed for safety or sanitation, photograph them clearly first. Be Careful With Contractors After A Storm After major storms, contractors may go door to door offering inspections or quick repairs. Many are legitimate, but homeowners should still be cautious. Before hiring a contractor: Verify licensing and insurance Check reviews and references Avoid signing blank contracts Be cautious with high-pressure sales tactics Ask for written estimates Understand payment terms Confirm who is responsible for permits Do not assign claim benefits without understanding the document A professional contractor can be helpful during recovery, but the homeowner should remain in control of the claim process and policy communication. Track Communication And Expenses Keep a claim folder with all important information. This can be digital, physical, or both. Include: Claim number Adjuster contact information Dates and times of calls Emails and letters Photos and videos Repair estimates Temporary repair receipts Hotel or temporary housing receipts, if applicable Contractor invoices Notes from inspections This record can help if there are questions about timing, scope, costs, or claim decisions. Organized documentation also makes it easier to compare estimates and understand what is being paid. Watch For Hidden Damage Windstorm damage is not always obvious immediately. A roof may look acceptable from the ground but still have lifted shingles, damaged flashing, or compromised seals. Water intrusion may appear later as ceiling stains, bubbling paint, soft drywall, or musty odors. After a storm, monitor the home for several days or weeks. If you notice new signs of damage, document them and notify the insurance company promptly. Hidden damage may be especially important after strong gusts, flying debris, or wind-driven rain. Delayed reporting can make it harder to connect the damage to the storm event. Know What May Not Be Covered Windstorm insurance does not cover every storm-related issue. Flooding from rising water is typically handled separately through flood insurance. Damage from poor maintenance, wear and tear, old roof conditions, or pre-existing problems may be limited or excluded. For example, if wind damages the roof and rain enters through the storm-created opening, the resulting interior damage may be evaluated under windstorm coverage. But if water enters because of long-term deterioration or an unrepaired leak, coverage may be more limited. This distinction is important for homeowners in Texas City, TX because severe weather can involve multiple causes of damage. Wind, rain, flood, and maintenance-related issues may be handled differently. Conclusion A windstorm claim is easier to manage when homeowners act quickly, document thoroughly, prevent further damage, and understand their policy . The most important steps are to stay safe, take photos and videos, make reasonable temporary repairs, report the claim promptly, and keep detailed records. Windstorm coverage can be complex, especially when deductibles, roof terms, separate policies, and flood exclusions are involved. Reviewing your coverage before storm season and following a clear checklist after damage can help protect your home and reduce claim confusion.
