Insurance Not Cover?

Your Texas homeowners policy covers a lot — but the gaps are where people get hurt. Flood, foundation movement, windstorm on the coast, slow leaks, and an aging roof are the big ones. Here's what's typically left out and how to fill each gap, from a licensed Texas agency.

Here's the thing most Texas homeowners don't find out until it's too late: your policy covers a lot, but it leaves out some of the exact things that go wrong here. A standard homeowners policy — the HO-3 form almost everyone has — is built to pay for sudden, accidental disasters like fire, theft, and most wind and hail. It is not built to pay for slow problems, predictable ones, or a handful of big perils that get their own separate policies.

We're a licensed Texas insurance agency, and this is the conversation we wish more homeowners had before a claim instead of after. This guide walks through what your policy typically doesn't cover — flood, foundation and soil movement, coastal windstorm, water damage and mold, roof wear, and a few more — and, just as importantly, how to fill each gap. One note up front: policies vary, so treat this as the common picture and confirm the specifics against your own policy.

Does Texas Homeowners Insurance Cover Flood Damage?

The short answer: no. Flood is excluded from every standard homeowners policy, and it's the single biggest gap for Texas homeowners.

This isn't specific to your insurer or your policy — it's true across the board. As the Insurance Information Institute and FEMA both spell out, damage from rising water — a swollen creek, streets that can't drain, storm surge pushed inland by a hurricane — is excluded from a standard HO-3 policy. The reason is simple: floods hit whole regions at once, creating losses so large they'd bankrupt a normal insurance pool.

The distinction that trips people up is where the water comes from. Water falling down — say, rain coming through a roof a storm just damaged — may be covered. Water rising up from outside is flood, and that's the exclusion. Flood coverage comes from a separate policy through the federal National Flood Insurance Program (NFIP) or a private flood insurer. And it matters more than most Texans assume: FEMA data shows a large share of flood claims come from properties outside the high-risk zones where lenders require coverage. If you're in the Pearland or greater Houston area, our Pearland flood insurance guide digs into local flood risk and how NFIP coverage works.

Does It Cover Windstorm and Hurricane Damage on the Gulf Coast?

The short answer: inland, usually yes — but along the Texas coast, wind and hail are often excluded and handled through a separate windstorm policy.

For most of Texas, your standard homeowners policy covers wind and hail damage. The catch is the coast. In the highest-risk coastal counties, many insurers exclude windstorm and hail from the standard policy, because a single hurricane can level an entire region at once. To make sure coastal Texans can still get covered, the state created the Texas Windstorm Insurance Association (TWIA) — a last-resort insurer, overseen by the Texas Department of Insurance, for wind and hail in the designated coastal areas.

TWIA coverage is available in 14 coastal counties — including Brazoria, Galveston, and Nueces — plus part of Harris County east of Highway 146. A few things worth knowing: TWIA covers wind and hail only (not fire, theft, or flood), it has to be paired with a standard homeowners policy, and your home may need to meet windstorm certification requirements to qualify. The detail that catches coastal homeowners off guard is timing — a TWIA policy can't be bought or changed once a storm has entered the Gulf of Mexico. Like flood, coastal wind coverage has to be in place well before hurricane season. Our Texas hurricane and windstorm guide covers how wind, hail, and named-storm deductibles fit together.

Does It Cover Foundation and Soil Movement?

The short answer: usually not when the cause is soil movement — and in Texas, that's a big deal because of our clay soil.

This is the exclusion Texas homeowners are most surprised by, and it's practically built for Texas conditions. Much of the state sits on expansive clay soil that swells when it's wet and shrinks when it's dry. That constant shrink-and-swell cycle pushes on foundations year after year — and standard policies almost universally exclude it. The specific language you'll find in nearly every Texas policy excludes "settling, cracking, shrinking, bulging, or expansion" of foundations, floors, walls, and the like. It's one of the most litigated phrases in Texas insurance.

There's an important exception: foundation damage is more likely to be covered when it's caused by a sudden covered peril — for example, a plumbing pipe that bursts under the slab and washes out the soil. That's a sudden accident, not gradual soil movement, so it can fall under coverage. The everyday clay-soil settling that cracks a slab over time does not.

Does It Cover Water Damage, Mold, and Sewer Backup?

The short answer: sudden water damage is usually covered; slow leaks, sewer backup, and most mold are not — unless you add coverage.

Water is where the "sudden versus gradual" rule matters most. Per the Texas Department of Insurance, sudden and accidental water damage is typically covered — a pipe that bursts in a freeze, a water heater that ruptures, a washing-machine hose that fails without warning. What's not covered is gradual damage: a pipe fitting that's been slowly dripping behind a wall for months, seepage, or anything that traces back to deferred maintenance. Insurance is built for the unexpected, not for upkeep.

Two related gaps catch people:

• Sewer and drain backup. If water backs up through your sewer line, sump pump, or drains, a standard policy generally won't cover it. Coverage is usually available as a separate endorsement — a small add-on that's well worth it in flood-and-storm country.
• Mold. Whether mold is covered depends entirely on its cause. If it grows out of a covered water source (like that burst pipe), it may be covered — but often with a limited payout. Mold from humidity, poor ventilation, or a long-ignored leak is excluded.

The throughline: fix leaks fast and keep up on maintenance, because "I didn't get around to it" is exactly what the gradual-damage exclusion is there to deny.

Does It Cover Roof Damage, Wear, and Old Age?

The short answer: a roof damaged by a covered event like wind or hail is typically covered — but wear, age, and neglect are not, and how you're paid depends on your coverage type.

Your roof is where two things collide: what caused the damage, and how your policy values it. On cause, the rule is familiar — if a covered peril (wind, hail, a fallen tree) damages your roof and rain gets in through that damage, the repair is generally covered. But if rain gets in because the roof simply wore out — curling shingles, degraded flashing, materials past their useful life — that's a maintenance issue, and it's excluded. A 20-year-old roof at the end of its life isn't "damaged"; it's used up.

Then there's how you're paid, and this surprises people after a storm:

Per the Texas Department of Insurance and standard industry practice. Depreciation isn't a penalty — it reflects that a 15-year-old roof isn't worth the same as a new one.

On an ACV policy, a hailstorm that totals an older roof might pay far less than a full replacement, because the insurer subtracts years of wear. If keeping your roof fully protected matters to you — and in Texas hail country, it should — replacement-cost roof coverage is worth asking about. It costs more, but it's the difference between a covered replacement and a surprise bill for thousands.

What Else Is Commonly Excluded?

The short answer: earthquakes and earth movement, neglect and wear, pests, and a few catastrophic risks — plus limits on high-value belongings you might not expect.

Beyond the big four, a standard Texas policy leaves out a handful of things worth knowing:

None of this means your homeowners policy is weak — it means it has a job, and that job is sudden, accidental loss. The exclusions are simply the map of where you need something extra.

The Bottom Line: What to Do About the Gaps

Here's the whole thing in a few sentences. A standard Texas homeowners policy is strong on sudden, accidental loss, but it leaves out flood, coastal windstorm, foundation and soil movement, gradual water damage, mold, sewer backup, pests, and plain wear and tear. Those aren't loopholes — they're the map of where you need something extra. Flood needs its own policy. Coastal wind runs through TWIA or a private windstorm policy. Foundation, sewer backup, higher mold limits, and replacement-cost roof coverage come through endorsements your insurer may offer.

The trap isn't that these gaps exist — it's not knowing which ones matter for your home until you're standing in the damage. That's exactly what we're here for. Our team will read through your current policy, flag the exclusions that actually matter where you live, and price the fixes that make sense — at no cost and no obligation. It's a short conversation now that beats a denied claim later.
