How to Determine If Your Property Needs a Separate Wind-Only Policy

If you own a home along the Texas Gulf Coast, there is a good chance your standard homeowners insurance does not cover wind and hail damage. In designated coastal counties, most insurers exclude wind perils entirely, leaving homeowners exposed to hurricanes, tropical storms, and severe thunderstorms. A wind-only policy is a specialized insurance product that covers property damage caused exclusively by wind and hail events. Understanding whether your property requires one can save you from devastating out-of-pocket costs after a storm. This guide walks you through the exact steps to find out.

What Is a Wind-Only Policy?

A wind-only policy is a stand-alone insurance contract that covers damage from high winds, hurricanes, tornadoes, and hail. It exists because standard homeowners policies in high-risk coastal areas often exclude these perils. Windstorm insurance is not the same as flood insurance; it does not cover rising water or storm surge.

If you live in a home covered by a standard HO-3 policy, wind and hail may already be included. However, along the Gulf Coast, insurers routinely remove that coverage, requiring a separate purchase.

Which Texas Counties Require Separate Windstorm Coverage?

Texas has 14 first-tier coastal counties where standard policies typically exclude wind and hail. These are designated catastrophe areas under the Texas Insurance Code. The Texas Department of Insurance (TDI) oversees the windstorm inspection program for these regions.

Texas City sits in Galveston County, one of the most hurricane-exposed areas in the state. If your property is here, a separate wind-only policy is almost certainly necessary. Learn more about windstorm insurance options available through our agency.

Step 1: Review Your Current Homeowners Policy

Start by pulling out your declarations page. A declarations page is the summary document at the front of your policy that lists covered perils, limits, and exclusions. Look for language such as "wind and hail excluded" or a separate wind/hail deductible endorsement.

Wind-Only Policy: Does Your Property Need One?

What to Look For

Check the "Exclusions" section for any reference to windstorm, wind-driven rain, or named storms. If these perils are excluded, you need a separate policy. Even if wind is included, verify your deductible. Some insurers apply percentage-based wind deductibles of 1% to 5% of dwelling coverage rather than a flat dollar amount.

When Wind Is Already Included

Most inland Texas homeowners have wind and hail coverage built into their standard policy. If your declarations page confirms wind coverage and you are not in a designated catastrophe area, a separate policy is likely unnecessary.

Step 2: Confirm Your Property's Location and Risk Zone

Your geographic location is the single biggest factor. Properties in the 14 first-tier counties and parts of Harris County east of Highway 146 fall within the designated catastrophe area. You can verify your property's status through TDI or by contacting a local agent.

Even if you own your home free and clear, skipping windstorm coverage in a coastal zone is a significant financial gamble. Explore our resource on assessing your home's windstorm risk by location for a deeper look at risk factors.

Mortgage Lender Requirements

If you have a mortgage on a property in a designated catastrophe area, your lender will almost certainly require proof of windstorm coverage before closing or at renewal. This requirement protects the lender's collateral and is non-negotiable in most cases.

TWIA vs. Private Windstorm Insurance

The Texas Windstorm Insurance Association (TWIA) is a state-created insurer of last resort that provides wind and hail coverage for properties in designated coastal areas. TWIA coverage is available in all 14 first-tier coastal counties and parts of Harris County, according to the TWIA eligibility page.

Private Market Alternatives

For the past 20 years, TWIA was the only option for Gulf Coast windstorm coverage. Today, private carriers and surplus-line insurers like Lloyd's of London also offer wind-only policies, sometimes with more competitive pricing or replacement-cost roof coverage. Brad Spurgeon Insurance Agency now offers windstorm coverage with two private companies alongside home policies that include wind.

The WPI-8 Certificate Requirement

A WPI-8 certificate is a TDI-issued document that confirms your property meets Texas windstorm building code standards. To qualify for TWIA coverage, your property must have a valid WPI-8 or equivalent certification. Without it, your home may be considered non-compliant and ineligible for coverage.

If you are replacing a roof, building an addition, or making structural repairs in a catastrophe area, that work must be inspected and certified. Read more about how windstorm inspections work to stay compliant.

Key Takeaways

  • A wind-only policy covers damage from high winds, hurricanes, and hail that standard homeowners insurance may exclude.
  • Properties in Texas's 14 first-tier coastal counties, including Galveston County (Texas City), almost always need separate windstorm coverage.
  • Review your declarations page carefully for wind/hail exclusions or percentage-based deductibles.
  • Mortgage lenders in coastal areas universally require proof of wind coverage.
  • TWIA serves as the insurer of last resort, but private market options are growing and may offer better terms.
  • A valid WPI-8 certificate is required for TWIA eligibility and may also be needed by private carriers.
  • Windstorm insurance does not cover flood damage; you need a separate flood insurance policy for that.

Frequently Asked Questions

Is windstorm insurance legally required in Texas?

No, Texas state law does not mandate windstorm insurance. However, mortgage lenders in coastal counties almost always require it as a condition of the loan.

How do I know if my standard policy excludes wind damage?

Check your policy's declarations page and exclusions section. If wind and hail are listed as excluded perils, you need a separate wind-only policy.

What is TWIA?

The Texas Windstorm Insurance Association is a state-created insurer of last resort. It provides wind and hail coverage for properties in designated catastrophe areas when private insurers decline coverage.

What counties are in the designated catastrophe area?

The 14 first-tier counties are Aransas, Brazoria, Calhoun, Cameron, Chambers, Galveston, Jefferson, Kenedy, Kleberg, Matagorda, Nueces, Refugio, San Patricio, and Willacy, plus parts of Harris County east of Highway 146.

Does windstorm insurance cover flooding?

No. Windstorm policies cover wind-driven damage only. Flood damage from storm surge or rising water requires a separate flood insurance policy.

What is a WPI-8 certificate?

A WPI-8 is a certificate of compliance issued by TDI confirming that a structure meets Texas windstorm building code standards. It is required for TWIA eligibility.

Can I get private windstorm insurance instead of TWIA?

Yes. Private carriers and surplus-line insurers now offer wind-only policies in many coastal areas, often with replacement-cost roof coverage and competitive rates.

Costs vary based on location, property value, and construction type. TWIA policies average between $2,000 and $2,480 per year. Private market rates depend on the carrier and your risk profile.
