Does homeowners insurance cover flood damage?

No. A standard homeowners policy excludes flood, and flood cover is a separate purchase — usually through the National Flood Insurance Program or a private equivalent. This is the most common and most expensive surprise in residential water damage. Read the flood exclusion in your own policy rather than relying on any summary, including this one.

What counts as a flood rather than water damage?

The division is about where the water came from, not how much damage it did. Water rising from outside — surface runoff, an overflowing watercourse, storm surge — is generally flood. Water escaping from a system inside the building, such as a burst supply line, is generally not. The same two inches on the same floor can fall under either policy depending on its origin, which is why establishing the source early matters so much.

Only 47.9% of homes in high-risk zones have flood insurance. Is that right?

That is what the FEMA data shows. 1,839,454 residential flood policies are in force inside Special Flood Hazard Areas against 3,839,194 residential structures in those areas, as of 2026-08-03 — leaving 1,999,740 homes uninsured for flood inside zones FEMA has mapped as high risk. Note the denominator counts residential structures, which is not identical to households or to mortgaged properties, so treat it as a close approximation rather than an exact rate.

Does a high claim count mean my state is dangerous?

Not directly, and this is the main thing to be careful about on this page. Claim counts are cumulative over the life of the programme and are not divided by the number of homes. A large state with a long history of flood insurance uptake will record more claims than a small state with little coverage, without being riskier per house. Use the count as evidence that flood claims happen at scale; use the coverage figures to decide anything.

I am not in a mapped flood zone. Am I fine?

No. A substantial share of NFIP claims come from outside high-risk zones, because flood maps describe modelled risk at a point in time and water does not consult them. Being outside a mapped zone changes what your lender requires and usually what a policy costs; it does not mean water cannot reach you.

Can I buy flood insurance after a storm is forecast?

No. FEMA states there is typically a 30-day waiting period for an NFIP policy to go into effect, unless the coverage is mandated, purchased as required by a government-backed lender, or related to a community flood map change. A policy bought when a storm is in the forecast will not cover that storm. The time to arrange flood cover is a season when nothing is happening.

How current is this data?

The claims dataset (OpenFEMA FimaNfipClaims v2, 2,721,780 records) was last refreshed 2026-07-21; the penetration dataset is as of 2026-08-03. Both were retrieved on 2026-09-05. FEMA revises these datasets, so figures move slightly between refreshes.

Does HyreRestore sell flood insurance?

No. We do not sell insurance, do not broker policies, do not perform restoration work and hold no dataset of losses. The counts on this page are FEMA’s; the percentages and rankings are arithmetic we performed on them and have labelled as ours.

What should I do if water has already entered the house?

Establish where it came from before anything else, because that determines which policy is even in play, and photograph everything before removal begins. Then work out whether filing helps you at all — our should I file tool covers the deductible arithmetic, and is it covered covers which bucket a typical HO-3 puts your loss in.

Check your flood claim history, and the gap nobody mentions

A standard homeowners policy excludes flood. Across the country almost nobody has bought the separate policy that covers it — including most people living inside the zones FEMA has drawn as high risk.

47.9% of mapped high-risk-zone homes carry flood cover 1,839,454 residential flood policies against 3,839,194 residential structures inside Special Flood Hazard Areas, as of 2026-08-03. That leaves 1,999,740 homes inside mapped high-risk flood zones with no flood policy at all. HyreRestore analysis of OpenFEMA NfipResidentialPenetrationRates — the percentage is ours, the counts are FEMA’s.

Pick your state. You get its NFIP claim history — 2,676,223 claims are on record nationally, 621,192 of them with a year of loss from 2015 — alongside the figure that actually decides what happens to you: how many homes carry flood cover at all. Nationally that is 2.89% of residential structures, and 47.9% inside FEMA-mapped high-risk zones.

Claim counts are lifetime-of-programme and are not normalised by housing stock, so they are not a per-home risk rate and a big state will accumulate more of them. The coverage figures are the ones to act on: if water enters from outside and there is no flood policy, the restoration is a cash question, not an insurance one.

The number that matters is the gap, not the claim count

A standard homeowners policy excludes flood. Flood cover is a separate purchase, and across the United States almost nobody has made it.

2.89% of American residential structures carry an NFIP flood policy. That is 3,161,236 policies against 109,326,879 residential structures, as of 2026-08-03. The figure is not low because flood is rare — it is low because flood cover is a separate product that has to be bought deliberately, and a homeowners policy gives no hint that it is missing until a claim is denied.

Inside mapped high-risk zones the coverage rate is 47.9%. Special Flood Hazard Areas are the zones FEMA has drawn as high risk, where a federally backed mortgage generally requires flood insurance. Even there, only 1,839,454 of 3,839,194 residential structures carry a policy — leaving 1,999,740 homes inside mapped high-risk flood zones with no flood policy at all. More than half.

This is the single most consequential fact on this site for a homeowner with water in the house. If the water came from outside — rising water, surface runoff, storm surge — and there is no flood policy, the restoration is not an insurance question. It is a cash question, and the sooner that is established the better every subsequent decision gets.

The claim counts below are context, not risk. 2,676,223 claims are on record across the programme, 621,192 of them with a year of loss from 2015 onward. They are lifetime-of-programme totals and they are not normalised by housing stock, so a large, long-insured state accumulates more of them without necessarily being more dangerous per house. Read them as evidence that flood claims happen at scale, not as a per-home probability.

Where mapped-zone homes are least insured

Ranked by the share of homes inside Special Flood Hazard Areas that carry a flood policy — lowest first. These are places where FEMA has drawn a high-risk zone and the overwhelming majority of homes inside it have no flood cover.

Where the claims have actually been paid

The six states with the most NFIP claims on record. Note how far apart the claim ranking and the coverage ranking are — a state can lead the country in claims and still leave half its mapped-zone homes uninsured.

What to do with this before there is water in the house

Five steps. None of them costs anything except the last.

Find out whether you are in a mapped zone
FEMA publishes the flood maps and they are free to search by address at msc.fema.gov. Being outside a mapped zone is not the same as being safe — a large share of NFIP claims come from outside high-risk areas — but it tells you what your lender and insurer are looking at.
Read the exclusion in your own policy
Do not take our word for it or your agent’s summary. Find the flood exclusion in your homeowners policy and read it. It is short, it is unambiguous, and reading it once is worth more than any statistic on this page.
Establish where water would come from
Flood cover and homeowners cover divide on where the water originated, not on how much damage it did. A burst supply line inside the house and two inches of surface water outside it are the same puddle and different policies.
Check whether your mortgage already requires it
A federally backed mortgage on a property in a Special Flood Hazard Area generally requires flood insurance. If you have one and no policy, something is wrong and it is worth resolving before a loss rather than after.
Price a policy before you need one
FEMA states there is typically a 30-day waiting period before an NFIP policy takes effect, with narrow exceptions for mandated cover, lender-required purchases and community map changes. The day a storm appears in the forecast is too late. This is the one step on the list that costs money, and the only one that changes the outcome.
