Does Homeowners Insurance Cover Flooding?

Flooding is both the most frequent and expensive natural disaster in the U.S. A 2020 report from First Street Foundation showed that 14.6 million properties in the contiguous United States are at a substantial risk of flooding. Home insurance is designed to provide financial protection when perils like natural diaster strikes — but floods aren’t one of them. By itself, home insurance will not help you with flood damage. To be financially protected from a flood, you will need flood insurance.   

Does home insurance cover flooding and flood damage?

A home insurance claim involving water can get complicated. Not all water damage is considered flood damage.

Although floods aren’t covered by home insurance, you can still financially protect yourself with a flood insurance policy. You can purchase it from the FEMA-managed National Flood Insurance Program (NFIP) or through a private flood insurance provider. Depending on your home insurance company, you may be able to purchase an NFIP policy through your carrier, instead of going to FEMA directly. Your home insurance provider may also partner with a private company to facilitate buying flood insurance.

What types of water and flood damage are covered by home insurance?

Flood damage isn’t covered by home insurance, but some water damage may be. Remember, just because there’s water in your home doesn’t mean that it automatically counts as flood damage.

There are different types of home insurance policies, each with varying levels of coverage. The two most popular are the HO-3 and HO-5. With these policy types, your home’s physical structure and the detached structures on your property are covered on an “open peril” basis. This means anything not specifically listed in your policy exclusions will be covered. While flood damage will still be excluded, you can likely file a claim for other types of sudden and accidental water damage. For instance, if your washing machine water supply hose breaks and damages your floors, your HO-3 or HO-5 home insurance policy would likely help with the cost of repairing your floors. However, repairing or replacing the machine itself may not be covered.

What about your personal belongings? With an HO-5 policy, your personal property is covered on an open peril basis, just like your dwelling and other structures. But, with an HO-3, your personal property is financially protected from the specific losses listed in your policy. These include: 

• Water damage from the weight of snow, ice or sleet
• Windstorms
• Freezing or burst pipes
• Accidental overflow of water from a household system 

What types of water and flood damage are not covered by home insurance?

While standard HO-3 or HO-5 home insurance can cover a variety of water damage types, there are types of damage that are not usually covered. Flooding, as you know by now, is one of them.

However, there are other types of water damage that aren’t covered. For example, if your sump pump can’t keep up during heavy rains and overflows, you may end up with damage to your home. This type of damage, called sewer backup, is not automatically included on most home insurance policies, but can often be added. Water and sewer backup is a common home insurance endorsement.Mudslides, mudflows and landslides can also cause water damage in your home, but these perils are typically excluded from coverage. According to the Insurance Information Institute (Triple-I), you may be able to buy special policies for mudflow and landslide coverage, but mudslides are generally not covered by any type of insurance.

Who needs flood insurance?

Because the risk of flooding is present across nearly the entire country, most homeowners should at least consider buying a flood insurance policy. If you have a mortgage and you live in a high-risk flood zone, you’ll likely be required to carry a policy. For homeowners who own the property in full or who are in lower-risk zones, coverage may not be required but could still be a good idea.

Coastal homes, homes near bodies of water and homes in low-lying areas may be especially vulnerable to floods, although homes at higher elevations or miles from lakes or rivers could also be affected during heavy rains. FEMA offers a flood map tool that allows you to search for your address and see what flood zone you are in.

Tips for purchasing flood insurance

Buying flood insurance may seem intimidating, but the process is similar to buying any other kind of coverage. While not every home insurance company will have flood insurance options, many do. If you’re shopping for coverage, you may want to follow these steps:

1. Ask if your insurer offers flood insurance policies. Some carriers offer their own privately underwritten flood insurance, or even a flood insurance endorsement for your home policy, and many others can facilitate the purchase of an NFIP policy.
2. Know what coverage you need. Flood policies only have two coverage types: dwelling and personal property. You can purchase a dwelling-only policy or you can choose to carry both coverage types, but you cannot have a personal-property-only policy. Understanding your coverage needs (which may mean working with an agent) can help you choose coverage wisely.
3. Shop around. Until relatively recently, flood insurance was available exclusively through the NFIP, meaning you had no choice where to get your coverage. Now, though, some insurers underwrite their own policies, which means you can shop around and compare rates.
4. Know the time constraints. Most flood policies come with a 30-day waiting period, which means your coverage won’t be effective until 30 days after you make the first payment. There are a few exceptions to this, but keep it in mind when you’re shopping. Additionally, don’t wait until a storm is coming to shop for coverage; many companies put moratoriums on their policies if the potential for damage is imminent.
5. Make a payment to purchase the policy. To start your coverage, you’ll need to make a payment. Most flood insurance policies must be paid in full; payment plan options are rare. If you pay your insurance through your mortgage escrow account, the company will likely bill your mortgage and you will not need to pay directly.

Frequently asked questions

• Does flood insurance have a deductible?
  

  Usually, flood insurance policies have a deductible, and the amount you pay will depend on the extent of the damage. Some flood insurance policies actually have two deductibles — one for dwelling coverage and one for personal property coverage.

• How much does flood insurance cost?
  

  The cost of your flood insurance will depend on several factors. The most impactful aspect of your premium is your home’s flood zone. Your home’s flood zone is an indication of how likely flooding is in your area. Generally, the more likely that flood damage is, the more you’ll pay for flood insurance. However, you can lower your flood risk by elevating your entire home, installing floor drains or filling in your basement, and that may lower your premium.

• Is flood insurance more expensive than home insurance?
  

  It depends. The average cost of homeowners insurance is $2,285 per year for $300,000 in dwelling coverage, as of October 2024. Home insurance generally provides coverage for many more scenarios than flood insurance, but that doesn’t mean it’s any more or less expensive. That will all depend on your flood zone and the features of your home. If you’re in a very high-risk zone, your flood insurance could be quite pricey. However, you can shop around to find cheaper flood insurance, just like you can find cheaper home insurance by comparing rates. While NFIP policies should cost the same no matter what company is facilitating the sale, private flood insurance rates vary and you might be able to find a cheaper policy.

• Does flood insurance cover hurricanes?
  

  Yes, flood insurance usually covers the flooding associated with hurricanes and storm surges. Keep in mind, though, that you shouldn’t wait for a storm to be upon you to shop for coverage. If a company knows that the risk of widespread flood damage is imminent, you may be barred from buying coverage, or the storm may fall outside the standard 30-day waiting period.

• How can I prevent flood damage?
  

  Making sure your gutters and downspouts properly drain can help prevent flood damage, as well as installing flood vents and waterproofing your basement. Some flood mitigation efforts, like elevating your home, can be expensive for many homeowners. Even something as simple as lining your home with sandbags can help lower your flood risk.
