Does home insurance cover flood damage in Texas — and how do you get flood insurance?

Home insurance and flood insurance are two separate questions for a Texas homeowner, and having the first does not settle the second. This guide goes through what the state's insurance regulator says about both.

The short version. In Texas, the Texas Department of Insurance (TDI) says in Flood insurance: Why you need a policy that "most home insurance policies don't cover flood damage" and that you might need a separate flood policy to make sure your property is covered. TDI's blog post Where else you can buy flood insurance says you can get flood insurance in Texas through the federal National Flood Insurance Program (NFIP) or from an insurance company. The first TDI page adds that most flood policies have a 30-day waiting period before they start.

Here's what we'll cover: whether your home policy covers flood, who requires flood insurance in Texas, where you can buy it, how much coverage TDI says a flood policy provides, and how the waiting period affects when you buy.

TDI says most home policies don't cover flood

A Texas home insurance policy may not cover flood damage. TDI's flood tip sheet says "most home insurance policies don't cover flood damage" and that, to make sure your property is covered, you might need a separate flood policy.

TDI's wording is about most policies, so it does not tell you what your own policy says. For that, check the policy language.

A practical first step is to look for a separate flood policy in your records. If you can't find one, ask your agent or insurance company whether flood is covered before you rely on it.

Is flood insurance required in Texas?

For a Texas homeowner with a mortgage, a flood insurance requirement can come from the lender and depends on where the home sits. TDI's flood tip sheet says that if your home is in a designated flood zone, your lender requires you to have flood insurance.

The tip sheet defines a flood zone as an area that has a 1% chance of being flooded in any given year.

TDI then adds that floods can happen anywhere, and gives a figure for NFIP claims outside the high-risk flood areas: "On average, 40% of the National Flood Insurance Program (NFIP) flood insurance claims occur outside the high-risk flood areas." That is the figure on TDI's page as last updated on 8/7/2025.

A lender's requirement does not mean a home outside a designated flood zone cannot flood, so that home still leaves you with a decision to make.

TDI says Texas is particularly prone to floods

TDI's flood tip sheet says Texas is particularly prone to floods, especially in two large parts of the state: the coast and Flash Flood Alley, a wide band that extends through Central and North Texas.

Almost every major city in Texas is in an area at high risk of flooding, the tip sheet adds.

If no lender has asked you for flood insurance, that may only mean you have no mortgage or sit outside a designated flood zone, and you can still look at flood coverage.

Where you can buy flood insurance in Texas

TDI describes two ways to buy flood insurance in Texas, the federal National Flood Insurance Program (NFIP) and an insurance company. Both are in its blog post Where else you can buy flood insurance, dated October 16, 2025.

• The National Flood Insurance Program (NFIP). According to the blog post, most people with flood insurance in Texas have a policy through the NFIP.
• An insurance company. You can also buy flood insurance from an insurance company, the post says, like you would buy your home or auto insurance.

To find a company that sells flood insurance, the blog post suggests asking your home insurance company if it sells flood insurance, or finding an independent agent, who can shop for you and find a company that offers it. TDI's flood tip sheet gives a similar starting point, which is to talk to your home insurance agent about getting a flood policy from your insurance company or the NFIP.

TDI's post also advises shopping around to find the coverage that fits your needs and budget, and gives the reason: "The coverage and premium can be different between companies."

Two situations get their own advice in the post. If you have a mortgage and your lender requires flood coverage, it says to be sure you know what coverages the lender requires and then ask each company if it provides them. If you're buying a home and need flood insurance, it says to ask if the seller has an NFIP policy that can transfer to you.

When you compare, line up what each option covers and what it costs, and check both against anything your lender asks for.

How much coverage you get

A flood insurance policy has its own limits, and TDI states them separately for the home and for belongings. From TDI's flood tip sheet, as last updated on 8/7/2025: "A flood insurance policy will cover your home up to $250,000. You'll need a separate flood policy for your personal belongings, which provides coverage up to $100,000."

• Building and contents are separate decisions. In TDI's description, the policy on the home and the policy on your personal belongings are two policies, so covering the structure does not by itself cover what is inside it.
• The figures are upper limits. TDI gives them as "up to" amounts. If rebuilding your home or replacing your belongings could cost more than those figures, ask the agent or company how the difference would be handled before you buy.

The tip sheet does not say which policies these limits apply to. TDI's blog post says coverage can be different between companies, so read the limits on any policy you are offered.

The 30-day waiting period

A flood insurance policy may not start on the day you buy it. TDI's flood tip sheet, as last updated on 8/7/2025, says: "Most flood policies have a 30-day waiting period before kicking in so don't wait for an approaching storm before deciding to buy coverage."

TDI's sentence is about most flood policies, so ask about the waiting period on the specific policy you are considering. Where a waiting period applies, a policy bought when a storm is already in the forecast may not be in effect when the storm arrives.

That makes timing part of the decision. You can look at flood coverage ahead of time, the same way you'd check your wind and hail deductible before hail season rather than after a storm.

What to do with all this

Checking your flood coverage in Texas comes down to five steps. The steps are Credify's own suggestions, and the facts behind them are in the TDI pages above.

• Confirm what you have. Look for a separate flood policy. If there isn't one, ask whether your home policy covers flood before you count on it.
• Find out whether your home is in a designated flood zone. Then keep in mind TDI's point that floods can happen anywhere.
• Compare both routes. Flood coverage is bought through the NFIP or a company that sells flood policies, as TDI describes, and its blog post advises shopping around because coverage and premium can differ between companies.
• Decide before a storm is approaching. Where a 30-day waiting period applies, the purchase date matters.
• Check the contents question separately. TDI describes coverage for personal belongings as a separate flood policy.
