What Is the Difference Between Flood Insurance and Homeowners?
Last updated October 26, 2026
The short answer
What Homeowners Insurance Covers
Homeowners insurance typically pays for water damage that happens suddenly and accidentally from inside your home. Examples include a broken water pipe, a leaking dishwasher, or an overflowing toilet. The policy usually covers the cost to dry out the area, repair the structure, and replace damaged belongings.
However, homeowners insurance has limits and exclusions. It usually does not cover damage from groundwater seeping through the foundation, or from water that backs up through sewers unless you added extra coverage. It also excludes flooding from outside sources, which is why a separate policy is often necessary.
Policies vary, and your insurer decides what is covered.
- Burst pipes and plumbing leaks
- Appliance overflows, like a washing machine
- Roof leaks from a storm (if wind caused the opening)
- Water damage from firefighting efforts
- Sewer backup only if you added that endorsement
- Sudden accidental discharge from a water heater
What Flood Insurance Covers
Flood insurance is a separate policy, usually through the National Flood Insurance Program or a private insurer. It covers damage caused by water that comes from outside your home, such as heavy rain flooding your yard, storm surge, or overflowing rivers and streams. This type of policy pays to repair your home's structure and replace your personal belongings.
Flood insurance is not part of a standard homeowners policy. Even if you live in a low-risk area, flooding can happen after intense storms or when drainage systems fail. In coastal regions with rainy summers and hurricane season, flood risk is worth considering.
- Rising water from rivers, lakes, or oceans
- Storm surge during a hurricane
- Heavy rain that pools on the ground
- Water from blocked storm drains
- Mudslides caused by flooding (in some policies)
- Damage to your foundation and crawl space from floodwater
Key Differences You Should Know
The main difference is where the water comes from. Homeowners insurance handles water that starts inside your home, like a pipe that bursts. Flood insurance handles water that starts outside and enters your home, like rain that soaks the ground and seeps in.
Another difference is how you buy each policy. Homeowners insurance is usually required by your mortgage lender and is sold by private insurers. Flood insurance is optional in most areas, though some lenders require it if you live in a high-risk flood zone. You can buy flood insurance through the government program or a private insurer.
- Homeowners covers internal water, flood covers external water
- Flood insurance is often a separate policy with its own premium
- Homeowners policies usually exclude flood damage
- Flood insurance may have a waiting period before it takes effect
- Both policies have deductibles, but they work differently
- Flood insurance is required by some lenders in high-risk zones
How to Decide What You Need
Check your homeowners policy to see what water damage it covers. Look for exclusions related to flooding, groundwater, and sewer backup. If you live in a flood-prone area, or if your mortgage lender requires it, you likely need flood insurance.
- Review your homeowners policy for water damage exclusions
- Check flood maps for your address to see your risk level
- Ask your lender if flood insurance is required
- Compare flood insurance costs from the NFIP and private insurers
- Think about the cost of replacing your home and belongings if a flood happens
- Act quickly to buy flood insurance, as there may be a waiting period
What to Do After Water Damage
If water damage happens, act quickly to dry the area and prevent mold. Turn off the water source if it is safe, and move valuable items to a dry place. Take photos of the damage before any cleanup, as those can help with your insurance claim.
For internal water damage, you may need to call a plumber to fix the source. For help with cleanup, local water damage pros can dry out your home and repair affected materials. For flood damage, you may need to contact your flood insurer and follow their instructions for filing a claim.
- Turn off the main water valve if a pipe bursts
- Remove standing water with a wet vacuum or mop
- Use fans and dehumidifiers to dry the area
- Throw away porous items like carpets and mattresses that got soaked
- Call a mold professional if you see mold growing
- Keep receipts for any emergency repairs you pay for

Does homeowners insurance cover flooding from heavy rain?
Usually no. Standard homeowners policies exclude flooding from outside sources, including heavy rain that pools on the ground and seeps into your home. You would need a separate flood insurance policy to cover that type of damage.
Is flood insurance required by law?
Flood insurance is not required by federal law for all homeowners. However, if you have a mortgage from a federally regulated lender and live in a high-risk flood zone, your lender will likely require you to buy flood insurance as a condition of the loan.
Can I buy flood insurance after a storm warning?
You can buy flood insurance at any time, but most policies have a 30-day waiting period before coverage starts. That means you cannot get a policy right before a storm and expect it to cover that storm. The sensible approach is to buy well in advance.
