Texas Windstorm Insurance and TWIA
Texas Windstorm Insurance Association (TWIA) is a state-created residual-market insurer for eligible property in a defined Texas coastal catastrophe area when at least one authorized insurer writing wind and hail coverage there has declined the risk.
- A TWIA policy generally covers only windstorm and hail damage to the property listed in the policy; it does not replace homeowners, commercial property, or flood insurance.

Windstorm insurance is a property policy or policy section that addresses wind and hail damage. It matters on the Texas coast because some private insurers exclude wind or hail from an otherwise available homeowners or commercial property policy, decline a coastal property, or offer coverage only on different terms. A property owner may then need a separate wind policy to complete the insurance program. That separate policy can leave a real gap if the owner assumes it covers every risk the home policy excludes.
TWIA is one possible source of coastal wind and hail coverage. The Texas Legislature created the Texas Windstorm Insurance Association as a residual-market insurer for eligible properties in the designated catastrophe area when coverage is not reasonably available through the private market. TWIA is not a general homeowners insurer and it does not insure every Texas coastal property automatically. The location, private-market declination, building-code evidence, flood-insurance rules, and property condition all matter.
What TWIA is—and what it is not
TWIA issues insurance policies, collects premiums, and pays covered losses. Its role is limited by law and its policy forms: TWIA coverage is for windstorm and hail damage to insured property. A standard TWIA policy does not provide fire, theft, liability, or flood coverage. A wind policy is therefore usually one component of a broader insurance arrangement, not a substitute for a homeowners, dwelling, commercial-property, or flood policy.
Think of a coastal residence as potentially having separate questions for each peril. If wind tears off roofing, the wind policy may be relevant. If a kitchen fire damages the house, the homeowners or dwelling policy is the place to look. If storm surge or rising water floods the first floor, a flood policy may be needed. If a visitor is injured and alleges negligence, a liability coverage grant is relevant. The name of the storm does not determine the cause of loss: wind damage and flood damage during the same hurricane can be handled under different contracts.
TWIA does not decide what another insurer covers. The owner should compare the full set of policies, declarations, exclusions, deductibles, covered locations, and insured property. One policy might cover the dwelling but another may address wind and hail, while a separate flood policy addresses qualifying flood loss. Differences in limits, deductibles, valuation, and definitions can create gaps even when every policy is active.
| Policy or coverage source | Typical role in a coastal insurance program | What to verify |
|---|---|---|
| Homeowners, dwelling, or commercial property policy | Covers the property and causes of loss granted by that policy; a coastal policy may exclude wind or hail | Whether wind and hail are included, excluded, or subject to a separate deductible; property and limits insured |
| TWIA windstorm policy | Windstorm and hail coverage for eligible property listed on its declarations | Insured buildings or contents, limits, deductible, policy term, exclusions, and other terms |
| Private-market wind policy | Wind and hail coverage offered by an insurer outside TWIA | Whether its terms coordinate with the underlying property policy and whether coverage is actually bound |
| Flood policy, often through NFIP | Flood coverage under its own definitions, limits, exclusions, and conditions | Whether the building and/or contents are insured, flood definition, waiting period, deductible, and limits |
Where TWIA coverage is available
TWIA coverage is restricted to the designated catastrophe area established by the Texas insurance commissioner. Current TWIA materials list all 14 first-tier coastal counties—Aransas, Brazoria, Calhoun, Cameron, Chambers, Galveston, Jefferson, Kenedy, Kleberg, Matagorda, Nueces, Refugio, San Patricio, and Willacy—and specified portions of Harris County east of Highway 146. The exact designated area is more precise than the everyday phrase “the Texas coast.” A coastal view, a coastal mailing address, or proximity to the water does not by itself establish eligibility.
The association’s coverage area is not the same thing as the entire seacoast territory used in insurance law. TWIA serves the designated catastrophe area where the state has found windstorm and hail insurance is not reasonably available. Before advising that a property qualifies, confirm the exact location through current TWIA materials or the agent application process. County alone can be insufficient for an address in Harris County because only designated parts are included.
Who may qualify for a TWIA policy
Eligibility is a combination of applicant and property requirements. The general checklist below follows TWIA’s current consumer guidance. It is a study summary, not a preapproval: TWIA reviews an application and may request more information, and the applicable statute, plan of operation, underwriting rules, and policy control.
- The property must be in the designated catastrophe area.
- The applicant must have been denied windstorm and hail coverage by at least one authorized insurer actively writing or renewing that coverage in the designated area. A declined quote should be documented and given to the agent; do not assume that contacting an insurer that does not write the risk satisfies the requirement.
- The property generally needs a windstorm Certificate of Compliance showing that applicable building-code requirements are met. Some residential properties may qualify under specific exceptions, but the exception is not a blanket waiver for every older home.
- Flood insurance proof is required for some properties when the statutory and TWIA conditions are all met. This is generally tied to a qualifying V-zone location, NFIP availability, and a structure constructed, altered, remodeled, or enlarged after September 1, 2009.
- The property must meet TWIA’s underwriting standards, including acceptable insurable condition. Unrepaired damage or a hazardous condition may affect eligibility.
The private-market declination requirement is often misunderstood. The current TWIA consumer page says an applicant must have been denied by at least one authorized insurer. It does not say that every insurer in Texas must reject the property. Still, the insurer must be one authorized and writing or renewing windstorm and hail coverage in the relevant area, so a random carrier’s refusal may not establish the statutory condition. Let the licensed agent confirm that the documentation is acceptable under current TWIA procedures.
The WPI-8 certificate and windstorm inspection
A Windstorm Certificate of Compliance is evidence that covered construction complies with applicable windstorm building-code requirements. TWIA calls these certificates WPI-8, WPI-8-E, and, for a historical period, WPI-8-C. Since June 1, 2020, the Texas Department of Insurance (TDI) issues WPI-8 and WPI-8-E certificates through its windstorm inspection program. TWIA accepted applications for WPI-8-C certificates only from January 1, 2017, through May 31, 2020; an existing WPI-8-C can still be relevant, but it is not the current route for a new certificate.
The certificate question can arise when a property is first insured and when improvements are made. TDI and TWIA identify examples such as new structures, additions or enlargements, windows, entry doors, garage doors, and certain roof or siding work. The applicable inspection and certification procedure depends on the work and timing. A homeowner should check with TDI or a qualified inspector before construction begins if certification may be needed; trying to reconstruct compliance after the work is complete can be more difficult.
TWIA lists limited residential exceptions. For example, some residential property built between 1988 and June 18, 2009 may be eligible without a certificate subject to a 15% surcharge based on and added to the policy premium. A separate exception may apply to some residential property that had private-market insurance on or after June 19, 2009, then was cancelled or nonrenewed without a required WPI-8. These are fact-specific legal exceptions, not a general promise that an uncertified home will qualify. Verify the current rule and evidence with the agent and TWIA.
A WPI certificate should not be confused with an underwriting inspection. The certificate addresses windstorm-code compliance for the construction or improvement. TWIA may separately inspect a risk, including by in-person inspection or other information, to confirm application details and acceptable condition. Passing one review does not automatically satisfy the other, and a certificate is not a warranty that the property will withstand every storm or that all future damage is covered.
Flood insurance can be a separate eligibility requirement
TWIA does not provide flood insurance. Its current guidance requires flood coverage only when all three conditions apply: some part of the property is in an NFIP V, VE, or V1–V30 flood zone; NFIP flood insurance is available for the property; and the structure was constructed, altered, remodeled, or enlarged after September 1, 2009. The exact legal rule and how a particular project is classified should be confirmed with the agent and current TWIA guidance.
This eligibility requirement is narrower than the practical need to consider flood coverage. TWIA strongly recommends flood insurance, and a mortgage lender may separately require it. Even outside a mapped high-risk zone, flooding can occur. Standard property policies commonly exclude flood, while NFIP coverage has its own policy definition, limits, waiting rules, and exclusions. Do not infer that a TWIA policy covers storm surge or that a wind policy will pay simply because wind drove water onto the property.
How to apply and when coverage begins
TWIA applications are submitted through an insurance agent licensed in Texas and registered with TWIA. TWIA does not sell a policy directly to an individual through its website. An agent can gather property facts—such as location, age, construction, roof, current insurance, requested limits, and prior declinations—then help identify required documentation and available coverage choices.
The process has several distinct stages: confirm the address is in the designated area; document a qualifying private-market declination; locate or obtain the building-code certificate or determine whether a narrow exception applies; provide flood-policy proof when required; and submit a complete application for underwriting. TWIA may review the application and property condition. If approved, TWIA issues an offer. The applicant then follows the payment instructions to start coverage. Submitting an application alone should not be described as proof that coverage is bound.
Timing matters in hurricane season. TWIA states that when a hurricane is in the Gulf of Mexico, it may not issue a new policy or increase coverage on an existing or renewal policy; this is called a policy moratorium. Do not wait until a storm is approaching to seek coverage or increase limits. The precise moratorium status and effective-time rules are operational details for the agent and TWIA to confirm.
What a TWIA policy generally covers
The declarations and policy form identify the property insured and its limits. TWIA offers property coverage categories for eligible residential and commercial risks, but the policyholder should not assume that every structure or item at an address is included. A dwelling, other building, business personal property, or residential contents must be addressed by the policy and its applicable terms. The form controls whether a particular item is covered property, how it is valued, what exclusions apply, and what duties follow a loss.
The covered peril is the key starting point: the loss must result from windstorm or hail as the policy defines it. For example, wind that damages an insured roof may present a TWIA claim. Water entering through a wind-created opening could require careful analysis of the facts and wording. Rising water, storm surge, surface water, or flood is not turned into wind damage merely because a hurricane caused it. A loss involving both wind and water may require separate policies, causation evidence, and close review of exclusions and any applicable concurrent-cause wording.
Limits, deductibles, and valuation terms matter as much as the peril grant. The policy declarations show the chosen limits and deductible, and the policy states how covered property is valued and what conditions apply. A windstorm deductible may be different from a deductible in an underlying homeowners policy. Compare dollar amounts and percentage bases rather than assuming the largest policy limit is what the insurer will pay for every claim. Avoid relying on an online average premium or a prior-year rate: rates and a property’s quoted premium can change.
Private wind coverage compared with TWIA
TWIA is a residual-market option subject to statutory eligibility. A private insurer may offer wind and hail coverage as part of a homeowners or commercial property policy, or through a separate private wind policy. Private-market availability and terms vary by insurer, location, property features, and underwriting. The owner can ask an agent to compare available private terms with TWIA, but should compare complete contracts rather than premiums alone.
| Comparison point | TWIA | Private-market wind coverage |
|---|---|---|
| Who can buy | Only applicants and properties meeting the statutory and underwriting eligibility rules | Subject to the insurer’s underwriting rules and offered product |
| Role | Residual-market source where qualifying wind coverage is unavailable in the private market | Voluntary coverage offered by an insurer; may be bundled or separate |
| Covered causes | Windstorm and hail only, subject to the policy | Read the contract; a wind policy may also be limited to specified causes |
| Other property risks | Does not provide fire, theft, flood, or liability coverage | A homeowners/commercial package may include other perils, but wind may be excluded or restricted; a standalone policy may be narrow |
| Application | Through a TWIA-registered Texas insurance agent; requires eligibility evidence and underwriting approval | Through the insurer or agent under the insurer’s procedures |
| Terms and cost | Set by current TWIA policy forms, filed rates, selected options, and property factors | Set by the private insurer’s forms, rates, underwriting, and property factors |
There is no universal rule that private wind coverage is broader or cheaper, or that TWIA is the best choice whenever a property is near the coast. A private carrier may have a package policy with terms that fit the owner’s needs; another may exclude wind. TWIA may be available only after the applicant meets its requirements. Ask what policy is actually being offered, when it takes effect, what causes of loss it covers, which deductible applies, and whether a different policy must be maintained.
Claims, appraisal, and records
After wind or hail damage, notify the insurer named on the policy and follow its claim instructions promptly. Preserve photos, repair invoices, inspection documents, and communications. Make reasonable temporary repairs to prevent further damage, but document the condition first when safe and keep receipts. TWIA’s claims guidance cautions policyholders not to make permanent repairs such as a roof replacement before the adjuster has inspected, unless immediate action is needed to protect people or property; coordinate emergency measures and claim handling with the insurer.
TDI’s TWIA complaint guidance says a claim generally must be filed within one year of the date of loss under the policy language discussed there. Because deadlines and extensions can depend on the policy and event, check the current policy and TDI guidance and report the loss promptly rather than treating the one-year period as time to wait. Keep proof of when the claim was reported and submit requested information through the stated channel.
An adjuster investigates the claim and estimates damage; that estimate is not the same thing as the coverage decision or the policy limit. TDI explains that appraisal addresses the amount of a covered loss, not whether the policy covers the loss. TDI’s current TWIA guidance describes a 60-day period after notice that a claim is accepted for requesting appraisal, subject to catastrophe-related extensions. Read the policy’s appraisal clause and current TDI instructions before relying on a deadline. A disagreement about whether flood, wind, or another cause is covered is a coverage dispute, not simply a disagreement over repair cost.
This article does not describe TWIA’s catastrophe financing, insurer assessments, or member-company obligations. Those are separate statutory and financial mechanisms and should not be confused with a policyholder’s premium, deductible, or claim payment. For an insured, the practical claim questions are the covered peril, insured property, policy limit, deductible, proof of loss, deadlines, and applicable claim-resolution process.
A practical exam method
- Identify the location. Is the property in the designated catastrophe area, rather than simply somewhere near the coast?
- Identify the source of coverage. Is the risk insured through a private policy, TWIA, or both? Has wind and hail actually been excluded from the underlying policy?
- Separate wind from water. Determine whether the facts describe wind or hail damage, flood, or a combination; use the policy definitions and exclusions rather than the storm’s name.
- Check eligibility evidence. Look for a qualifying insurer declination, building-code certificate or narrow exception, required flood-insurance proof, and insurable condition.
- Read the declarations and form. Confirm covered property, limits, deductible, policy term, valuation terms, exclusions, and notice duties.
- For a disputed claim, distinguish coverage from amount. Appraisal can address the amount of a covered loss; it does not itself decide whether the cause or property is covered.
Frequently asked questions
These answers summarize general TWIA and Texas windstorm concepts. Exact eligibility and payment depend on the current statute, TWIA requirements, and the policy issued for the property.
Does TWIA cover all hurricane damage?
No. TWIA covers windstorm and hail damage to property insured by its policy. It does not cover flood, fire, theft, or every loss that happens during a hurricane. Flood and other causes need to be evaluated under separate policies.
Does every coastal Texas home qualify for TWIA?
No. The property must be in the designated catastrophe area and meet the private-market declination, code-certification or exception, flood-insurance-if-required, and underwriting rules. A location on the coast alone is not enough.
Do I have to be rejected by every private insurer?
TWIA’s current guidance states that an applicant must be denied by at least one authorized insurer writing or renewing windstorm and hail coverage in the designated area. An agent should confirm that the declination satisfies current documentation requirements.
Does TWIA cover flood or storm surge?
No. TWIA does not provide flood insurance. Storm surge and other flood losses should be evaluated under a flood policy’s definition and coverage terms. The fact that wind and flooding occurred in the same storm does not merge the policies.
What is a WPI-8?
A WPI-8 is a TDI Certificate of Compliance associated with new or ongoing improvements; a WPI-8-E is issued for completed improvements. TWIA accepted applications for WPI-8-C certificates only during 2017–2020. The certificate documents applicable windstorm-code compliance; it is distinct from TWIA’s underwriting review.
Can I apply directly to TWIA?
A Texas-licensed agent registered with TWIA submits the application. If the application is approved, TWIA makes an offer, and the required payment starts coverage. Do not assume a request or incomplete application has bound insurance.
What does an appraisal decide?
Under TDI’s TWIA guidance, appraisal is used to resolve the amount of a covered loss. It does not decide whether a loss is covered. Check the issued policy and current TDI claim information for the procedure and deadline.
Prepare for the Texas P&C exam
The Texas Property and Casualty exam course helps you practice distinguishing windstorm coverage, flood coverage, eligibility evidence, and policy limits. For a real property, compare the issued policies and ask a licensed agent or insurer to confirm eligibility and coverage.
Common questions
What does TWIA insurance cover?
TWIA policies cover windstorm and hail damage to the property insured by the policy, subject to limits, deductibles, exclusions, and conditions. TWIA does not provide flood, fire, theft, or liability insurance.
Who is eligible for TWIA?
The property must be in the designated catastrophe area; an applicant generally needs a qualifying private-market declination; the structure needs applicable windstorm-code certification or a specific exception; required flood insurance must be documented; and the property must meet underwriting standards.
Does TWIA cover flood damage?
No. TWIA does not provide flood insurance. A separate flood policy may be available through NFIP or another insurer, and its own terms determine coverage.
What is the difference between WPI-8 and WPI-8-E?
TDI describes WPI-8 as a certificate for new and ongoing improvements and WPI-8-E as a certificate for completed improvements. TWIA accepted WPI-8-C applications only from 2017 through May 31, 2020.
Do I need flood insurance to qualify for TWIA?
Only some properties have a TWIA flood-insurance eligibility requirement. Current TWIA guidance generally requires it when the property is in an NFIP V zone, NFIP flood coverage is available, and the structure was constructed, altered, remodeled, or enlarged after September 1, 2009. Confirm the exact facts and rule with the agent.
Can TWIA issue a policy during a hurricane threat?
TWIA says a moratorium can prevent a new policy or an increase in coverage while a hurricane is in the Gulf of Mexico. Secure coverage well before storm activity and confirm current status and effective-time rules with the agent.
