What Is the Difference Between Flood Insurance and Home Insurance?
Last updated October 26, 2026
The short answer
What Home Insurance Covers
Home insurance, also called homeowners insurance, protects your dwelling and belongings against a list of named perils. Those perils often include fire, wind, hail, lightning, theft, and sudden water damage from a burst pipe or an overflowing appliance. If a pipe breaks in your wall, your home policy usually pays for the water extraction, drying, and repairs.
The key limit is the source of the water. If water comes from above, like rain through a damaged roof, or from inside, like a plumbing failure, your home insurance may respond. But if water rises from the ground, such as a river overflowing or heavy rain pooling outside, that is considered flooding and falls outside a standard home policy.
What Flood Insurance Covers
Flood insurance is a separate policy that covers damage caused by rising water, which is the most common exclusion in home insurance. It typically pays for cleanup, structural repairs, and replacement of personal belongings damaged by floodwater. This type of coverage is often required if you have a mortgage on a property in a high-risk flood zone.
Flood policies are usually backed by the National Flood Insurance Program, though private options exist. They have their own deductibles and coverage limits, and they do not cover everything. For example, damage to a basement from seepage or a sewer backup may not be covered unless you add an endorsement.
- Covers rising water from rivers, streams, and coastal storm surge
- Covers damage from heavy rain that pools on the ground
- Usually excludes sewer backup unless added separately
- Requires a separate premium and deductible
- Available even if you are not in a high-risk zone
How to Know Which Policy Applies
The easiest way to tell is to look at the water source. If a tree branch punches a hole in your roof and rain pours in, that is wind and hail damage, so your home insurance likely applies. If a creek overflows into your yard and water enters your crawl space, that is flooding, so your flood insurance is the one to contact.
Some events are less clear, like a sump pump failure during a storm. In that case, the cause matters. If the pump broke from normal wear, your home policy might cover it. If floodwater overwhelmed the pump, the flood policy may be the right claim. Read both policies and keep copies of them handy.
Why Tulsa Homeowners Should Check
Spring in this region brings hail and thunderstorms that can produce heavy rain and street flooding. Even outside a designated floodplain, intense downpours can push water into low-lying areas. A flood policy may be worth considering even if you are not in a high-risk zone.
Your mortgage lender may require flood insurance if your property is in a high-risk zone. But even if it is not required, you can purchase it. Talk to your insurance agent about your specific address and the elevation of your home. Policies vary, and your insurer decides what is covered. They can tell you if flood coverage is available and what it would cost.

- Ask your agent about flood coverage options
- Review your home policy for water damage exclusions
- Keep a copy of both policies in a dry, safe place
- Update your coverage after any major home renovation
What to Do After Water Damage
If water enters your home, act quickly to reduce further damage. Turn off the water supply if the leak is from a pipe, and shut off electricity in affected areas if it is safe to do so. Move valuable items to a dry spot and take photos of the damage for your claim. Do not throw anything away until your insurance company tells you to.
For cleanup, you can call local water damage pros to extract standing water and dry out the structure. They can also inspect for hidden moisture and help with repairs like drywall or flooring. Their work is separate from your insurance claim, but they can document conditions that may be useful.

Is flood insurance required by law?
Flood insurance is not required by federal law, but your mortgage lender may require it if your home is in a high-risk flood zone. If you have a federally backed mortgage and live in a special flood hazard area, you must carry flood insurance as a condition of the loan.
Does home insurance cover sewer backup?
Most home insurance policies do not cover sewer backup by default. You can usually add a sewer backup endorsement for an extra premium. Flood insurance also typically excludes sewer backup, so check both policies to see if this risk is covered.
Can I buy flood insurance if I rent?
Yes, renters can buy flood insurance to cover their personal belongings and the contents of their rental unit. The building structure is the landlord's responsibility, but your possessions are not covered by the landlord's policy. A separate renters flood policy can protect your furniture, electronics, and clothing.
