If you're buying a home in Houston, or you just opened a renewal notice and winced, this guide explains what actually sets a homeowners insurance premium here, which parts of the policy matter most in a storm-prone city, and how to compare quotes without getting surprised later. It's built from Texas Department of Insurance (TDI) guidance and the rules of the state's two backup insurers, checked on October 21, 2026.
TL;DR
- Your premium depends mostly on your home's replacement cost, age and condition, construction materials, location, nearby fire protection, your claims history and, with many companies, your credit, according to TDI.
- In Houston the biggest money is often in the deductible, not the premium. A percentage wind and hail deductible is figured on your dwelling coverage amount, not on the size of the claim.
- Check whether the roof is covered at replacement cost or actual cash value. On an older roof, that one line can mean thousands of dollars after a hailstorm.
- A standard homeowners policy doesn't cover flood. That's a separate policy with its own waiting period.
- Only a small part of Harris County (east of State Highway 146 in La Porte, Morgan's Point, Pasadena, Seabrook and Shoreacres) is in the area served by the Texas Windstorm Insurance Association.
- Compare sample rates on the state's HelpInsure.com, then get real quotes from at least a few companies.
What drives a Houston homeowners premium
TDI lists the factors most companies use when they price a homeowners policy in its shopping guide for home and auto insurance. Here's how each one tends to play out for a Houston house.
The cost to rebuild, not the sale price
Insurers price the dwelling on what it would cost to rebuild the house, and TDI notes that homes with higher replacement costs carry higher premiums. That number isn't your purchase price or your HCAD appraisal. A Heights lot can be worth far more than the bungalow on it, while a large newer home in Cypress can cost a lot to rebuild even if it sold for less. Ask the agent what rebuild figure the quote assumes and whether it looks right for the square footage and finishes.
Age, condition and the roof
Companies can't turn you down just because of your home's age or value, but TDI says they can charge you more. The roof gets the closest look. TDI's guide to insurance and your roof says your insurer will inspect the roof when you apply and may charge more or refuse coverage based on what it sees.
Construction and location
Premiums are higher for houses built completely of wood and lower for brick or stone, and higher in areas with more storms or crime. Being close to a fire station lowers the premium. Two similar houses a few miles apart in Harris County can be priced differently for these reasons alone.
Your claims history and credit
Past claims can raise your premium, and some companies use your credit score to set rates. TDI notes that a company can't turn you down based only on your credit. If you're shopping right after a claim, expect that to show up in the quotes.
Why we don't quote an "average" Houston premium
You'll see national websites publish a single average cost for Houston home insurance. We don't, for the same reason we don't for flood insurance: the number for your house depends on its rebuild cost, roof, deductible choices, claims history and credit, so a citywide average tells you very little about your quote. TDI's own advice is to compare sample rates on HelpInsure.com, a state site run by TDI and the Office of Public Insurance Counsel that covers policies from many of the largest insurance groups in Texas, and then call your top choices for actual quotes.
If you're buying, get a real quote early in your option period, once you know the roof age and the inspection results. Insurance is a monthly cost on top of the mortgage and property taxes, and it belongs in your budget alongside the numbers in our guide to how much house you can afford in Houston.
Deductibles: where Houston owners get surprised
A low premium with a high deductible can cost you more than a higher premium after the first storm. Texas policies often carry more than one deductible, so read them all on the declarations page, the summary page that lists your coverages, limits and deductibles.
Flat versus percentage deductibles
A flat deductible is a dollar amount, like $1,000. A percentage deductible is a share of the amount your house is insured for, not of the claim. TDI's deductible guide gives this example for a home insured for $150,000: with a $500 deductible, a $6,500 hail repair pays out $6,000, but with a 5 percent deductible ($7,500), the company pays nothing because the repair is smaller than the deductible.
Separate deductibles for storms
The Office of Public Insurance Counsel, the state agency that represents insurance consumers, explains that a policy may have a separate wind and hail deductible, a named storm deductible, or a hurricane deductible, and that when several could apply, typically only the largest one does. Ask your agent which deductible would apply to hail, a tornado, a tropical storm and a hurricane, and translate each percentage into dollars before you compare quotes.
What a higher deductible saves
TDI says switching from a $500 to a $1,000 deductible can save as much as 20 percent on premiums. That can be worth it if you have the cash set aside. OPIC also warns that it's illegal for a contractor to offer to waive your deductible without your insurer's consent.
Replacement cost or actual cash value
This is the coverage detail most worth checking on a Houston policy. Replacement cost pays to repair or replace at today's prices. Actual cash value pays today's price minus depreciation for age and wear.
TDI's example uses a 10-year-old roof that would cost $10,000 to replace today. With replacement cost coverage and a $2,000 deductible, the company pays $8,000. If the actual cash value is $7,000, an actual cash value policy pays $5,000 after the same deductible, so you'd be out $5,000 instead of $2,000.
TDI also notes that some companies switch an aging roof to actual cash value at renewal, and might not cover a roof in poor condition at all. Read every renewal for that change. With replacement cost coverage, the company usually pays a roof claim in two checks: a partial payment first, and the rest after repairs have started.
What a Houston policy leaves out
Flood is a separate policy
Home policies don't cover flood damage. TDI points out that more than half of the homes flooded by Hurricane Harvey were outside designated flood zones, and most flood policies have a 30-day waiting period. Our guide to flood insurance in Houston covers how those policies are priced and when a lender requires one.
Wind near Galveston Bay
For most of Houston, wind and hail are part of the homeowners policy. The exception is the bay shore. TDI says that if you live on the coast or in Harris County on Galveston Bay, your homeowners policy probably won't cover windstorm and hail. The Texas Windstorm Insurance Association (TWIA) sells that coverage, and in Harris County its area covers only property that is both east of State Highway 146 and inside the city limits of La Porte, Morgan's Point, Pasadena, Seabrook or Shoreacres, per the TDI Harris County wind map. To qualify, you must have been turned down by at least one private insurer, and the house generally has to be certified as built to the applicable windstorm building code. Buyers in those areas should ask the seller for the home's windstorm certificate.
Add-ons worth asking about
TDI lists common endorsements that extend a policy, including backup of sewers or drains, foundation damage, mold removal, and water damage from plumbing or air conditioning systems. Foundation and plumbing coverage come up often on Houston's clay soils and slab homes, so ask what each quote includes.
If companies keep saying no
If you can't find a company to insure your home, the Texas FAIR Plan Association sells homeowners coverage of last resort. You need declinations from at least two insurers licensed and writing property insurance in Texas, you can't qualify if a company has offered you a policy or renewal, and you apply only through an agent. You also have to shop the regular market again every two years. TDI says FAIR Plan coverage costs more than coverage from a standard company, and that surplus lines policies an agent may suggest come with fewer consumer protections.
How to shop and lower the premium
- Start with HelpInsure.com for sample rates, complaint records and financial ratings, then call two or three companies or an independent agent for real quotes.
- Use TDI's shopping checklist to compare the same dwelling amount, deductibles and roof coverage across quotes.
- Ask about discounts TDI lists: a monitored burglar or fire alarm, a sprinkler system, bundling other policies, and three years without a claim.
- Ask whether impact-resistant roofing earns a discount if you're replacing the roof. TDI says some companies offer one.
- Keep up the roof: trim overhanging limbs, clean gutters and check for missing shingles after storms.
- Don't cancel your current policy until the new one is in place or you have written proof of coverage.
FAQ
Does homeowners insurance in Houston cover flooding?
No. A standard homeowners policy doesn't cover flood damage. You need a separate flood policy, usually through the National Flood Insurance Program, and most have a 30-day waiting period.
What's a percentage deductible?
It's a deductible figured as a share of your dwelling coverage, not of the claim. On a home insured for $300,000, a 2 percent deductible means you pay the first $6,000 of a covered loss.
Do I need TWIA coverage in Houston?
Only if your home is in the small part of Harris County TWIA serves: east of State Highway 146 and inside the city limits of La Porte, Morgan's Point, Pasadena, Seabrook or Shoreacres. Elsewhere in Houston, wind and hail are usually part of your homeowners policy.
Why did my premium go up when I didn't file a claim?
Rates can change for a whole area or company, and your own rebuild cost, roof age or credit can change too. TDI recommends shopping regularly, since you often get the best rates when you're willing to switch companies.
Can an insurer refuse to cover my roof?
Yes. TDI says a company may charge more or decline coverage based on its roof inspection, and might not cover a roof in poor condition at all.
What if no company will insure my house?
After two declinations from insurers licensed and writing in Texas, an agent can apply for you with the Texas FAIR Plan Association. It costs more and has to be re-shopped every two years.
When should a buyer get an insurance quote?
During the option period, once you have the inspection report and know the roof's age. A surprise roof issue or a high quote is easier to handle before the option period ends.
One last thing
Insurance belongs in your offer math, not your closing-week checklist. If a home's roof, location or claim history could make it hard or expensive to insure, it's better to know while you can still negotiate.
