Windstorm insurance in Texas — who needs a separate policy, and how TWIA works

Most guides to Texas home insurance — including ours — explain wind and hail as something your homeowners policy covers, just with its own deductible. For most of the state, that's right.

On the coast, it can be wrong in a way that matters enormously. The Texas Department of Insurance (TDI) puts it plainly: "If you live along the coast, your homeowners insurance might not cover wind and hail damage. You'll need to buy a separate windstorm policy."

That is a different situation from having a high deductible. It's the difference between a large out-of-pocket cost and no wind coverage at all. Here's what we'll cover: who this applies to, where the coverage actually comes from, what it takes to qualify for a TWIA policy, the inspection requirement that catches people out after a roof replacement, and the deadline that closes before every storm.

Where the line falls

TDI draws the distinction by geography:

• Inland Texas: "If you live anywhere in Texas – except along the coast – you probably have wind and hail coverage in your homeowners policy. Your homeowners policy will pay for wind and hail damage much like it pays for fire, lightning, or theft, although you may have a different deductible for windstorm damage."
• The coast: "If you live along the coast, your homeowners insurance might not cover wind and hail damage. You'll need to buy a separate windstorm policy. Many people get this coverage from a Texas Windstorm Insurance Association (TWIA) policy. But ask your agent about your options."

The area in question is defined, not vague. TDI: "Properties in 14 coastal counties and in parts of Harris County east of Highway 146 are in a designated catastrophe area. Homeowners in these areas may not be able to get private insurance that covers windstorm and hail damage."

Note the word may. Being in the catastrophe area doesn't automatically mean you're on a separate windstorm policy — some coastal homeowners do hold private wind coverage. It means you can't assume. If you live in that area and you have never specifically checked whether wind and hail is on your homeowners policy or on a second policy, that's the single most valuable thing you could look up today.

What windstorm insurance actually covers

TDI's definition is broader than the name suggests: "Windstorm insurance pays to repair or rebuild your house if it's damaged by hail or wind, from a tornado, thunderstorm, or hurricane. Some people call it hurricane insurance."

So it isn't hurricane-only. Hail off a spring thunderstorm falls under the same coverage.

It's also worth being precise about what it is not. Wind and water are separate perils with separate policies, and TDI's own comparison chart lays out the three:

• Homeowners — "To protect your house and things." Covers "Damage from fire, lightning, theft, wind, hail, and more."
• Flood — "Most home policies don't cover floods." Covers "Damage from rising water."
• Wind/hail — "Most home policies on the coast don't cover wind and hail." Covers "Damage from wind and hail."

A hurricane can easily produce all three kinds of damage in one night, which is why a coastal home can need all three policies — and why "I have homeowners insurance" doesn't settle the question on the coast.

Is it required?

TDI: "Windstorm insurance isn't required by law in Texas. But if you live near the coast and have a mortgage, your lender will likely require you to have windstorm coverage."

That's the same pattern as flood: the requirement, where it exists, generally comes from your lender rather than from the state. In practice, for a mortgaged coastal home, the absence of a legal requirement rarely makes the coverage optional.

How you qualify for a TWIA policy

TWIA is an insurer of last resort, and TDI describes it that way: "The Texas Windstorm Insurance Association (TWIA) sells wind and hail coverage for coastal residents who have been turned down by an insurance company."

TDI lists three conditions. To get a TWIA policy, you must:

1. "Live or own a business in TWIA's service area."
2. "Have asked an insurance company for wind and hail coverage and been turned down."
3. "Get an inspection and certificate showing that your home or business was built or renovated according to certain construction codes."

The second condition is the one people skip past. TWIA is not a shopping option you pick because it looks convenient — a turndown from a private company comes first. That is also why it's worth asking an agent to look at private wind markets before you assume TWIA is the answer; TDI's own advice on the coastal case is "ask your agent about your options."

TDI also flags two additional possibilities: "Depending on where you live, you might need flood insurance before you can get a TWIA policy. You also might need a home inspection by an engineer or windstorm inspector."

The inspection requirement — and why a roof replacement can trigger it

The third condition is where coastal homeowners most often get stuck, usually after doing work on the house.

TDI: "To buy a TWIA policy, most homes and properties must have a certificate of compliance verifying that the structure meets applicable building codes and can withstand high winds and hail."

There are two certificates, and which one you need depends on when the property is inspected:

• WPI-8 — "issued for ongoing construction. These inspections can be done by an appointed Texas licensed professional engineer or TDI windstorm inspector while the work is underway."
• WPI-8-E — "issued for completed construction. These inspections can be done by a Texas licensed professional engineer."

The order matters financially. TDI: "Because it's more difficult to inspect a completed structure for building code compliance, it may cost more." Getting the inspection arranged while the work is happening is cheaper than getting it certified afterward.

And the trigger is wider than new construction. TDI: "Most new construction, roof replacements, major repairs, and other alterations require an inspection and certificate of compliance." A roof replacement is on that list — which means the hail claim that got your roof replaced can also create a certificate obligation for your wind coverage.

TDI lists projects that don't require an inspection:

• "Roof repairs of less than 100 square feet that don't involve decking."
• "Painting, carpeting, cabinets, and other non-structural items."
• "Repairs or replacement of fences, gutters, decorative shutters, steps, and screen doors."
• "Plumbing and electrical repairs."
• "Replacement of glass in windows or doors."

TDI's advice before the work starts: "Make sure to ask your contractor how they will meet the requirements for an inspection and get a certificate of compliance." That question belongs in the contractor conversation, not in the insurance conversation six months later.

You can also check what's already on file. TDI: "You can check for a property's certificate of compliance (WPI-8 or WPI-8-E) on the TDI Windstorm website." For certificates TWIA itself issued "between January 1, 2017, and May 31, 2020," TDI points to TWIA's own lookup tool.

The deadline that closes before every storm

This is the part that turns windstorm insurance into an off-season job.

TDI, twice, in two different places: "Don't wait until the last minute to buy wind and hail insurance. You can't get a TWIA policy if there's a hurricane in the Gulf of Mexico." And: "Don't wait until the last minute to buy wind and hail insurance. TWIA won't sell you a policy if there's a hurricane on the way."

Stack that against the inspection requirement and the timeline gets long. If a named storm forms and you discover then that your wind coverage has a gap, an inspection and certificate can't be arranged inside that window — and TWIA is closed for new business anyway. The work has to happen on a calm week.

If you have to file a TWIA claim

Two deadlines are worth knowing before you need them. TDI: "You have one year from the storm to file a claim." And on disputes: "You have 60 days from the date TWIA accepted your claim to dispute the claim amount and ask TWIA for an appraisal."

TDI's first step on a problem claim is to go back to TWIA: "If you have issues or complaints with a TWIA claim, call TWIA first to talk to them about it." If that doesn't resolve it, TDI names its own coastal team as the next stop. The general process, TDI says, "is similar to filing a homeowners claim" — how to file a hail or storm damage claim in Texas walks through what that looks like in practice.

What to do with this

• Find out which policy carries your wind and hail coverage. On a coastal home, check whether it's inside your homeowners policy or on a separate windstorm policy. Your Declarations page is where to look — and if wind and hail isn't there, it's somewhere else, or nowhere.
• If you've replaced a roof or done major work, check your certificate. TDI's windstorm site lets you look up whether a WPI-8 or WPI-8-E exists for the property.
• Do it out of season. Nothing about this process can be completed with a storm in the Gulf.
• Ask about private wind markets before assuming TWIA. TWIA requires a turndown first, and TDI's own guidance is to ask your agent about your options.

If you're not certain what your policy does on the coast, that uncertainty is the finding. It's worth resolving on a quiet week rather than a forecast week.

Key facts

• Coastal homeowners policies may exclude wind and hail entirely. TDI: "If you live along the coast, your homeowners insurance might not cover wind and hail damage. You'll need to buy a separate windstorm policy."
• Inland is different. TDI: "If you live anywhere in Texas – except along the coast – you probably have wind and hail coverage in your homeowners policy."
• The area is defined. TDI: "Properties in 14 coastal counties and in parts of Harris County east of Highway 146 are in a designated catastrophe area."
• Not required by law; often required by a lender. TDI: "Windstorm insurance isn't required by law in Texas. But if you live near the coast and have a mortgage, your lender will likely require you to have windstorm coverage."
• TWIA has three eligibility conditions — living in the service area, having "asked an insurance company for wind and hail coverage and been turned down," and getting "an inspection and certificate showing that your home or business was built or renovated according to certain construction codes."
• Two certificate types. A WPI-8 is "issued for ongoing construction"; a WPI-8-E is "issued for completed construction," and TDI notes the completed-construction inspection "may cost more."
• Roof replacements can trigger the requirement. TDI: "Most new construction, roof replacements, major repairs, and other alterations require an inspection and certificate of compliance."
• There is a hard cut-off. TDI: "You can't get a TWIA policy if there's a hurricane in the Gulf of Mexico."
• Claim deadlines. TDI: "You have one year from the storm to file a claim," and "60 days from the date TWIA accepted your claim to dispute the claim amount and ask TWIA for an appraisal."

Take the next step

Coastal wind coverage is the one part of a Texas home insurance setup that can't be fixed in a hurry. The eligibility step, the certificate, and the storm cut-off all have to line up on a calm week — and the homeowners who find out too late are usually the ones who assumed wind was already handled inside their existing policy.
