Hurricane coverage: wind, flood and storm surge
A standard homeowners policy pays for hurricane wind damage but not for flood or storm surge. What each policy covers, where the gaps are and what to check.
A standard homeowners policy covers the wind damage a hurricane causes: a torn-off roof, a tree through the garage, rain that enters through a hole the wind opened. It does not cover flood or storm surge, which needs a separate flood policy from the National Flood Insurance Program (NFIP) or a private insurer. In many coastal areas the wind coverage itself comes with a separate percentage deductible, and in a few it has been carved out of the homeowners policy altogether.
Most of the confusion after a hurricane comes from one fact: a single storm produces several kinds of damage, and each kind is answered by a different policy, a different deductible and sometimes a different claims process.
One storm, three sources of damage
| What happened | Which policy usually answers | Notes |
|---|---|---|
| Shingles stripped, roof deck damaged | Homeowners (Coverage A) | Wind or hurricane deductible applies |
| Tree falls on the house or garage | Homeowners (Coverage A or B) | See falling tree damage: who pays and when for the tree-removal limits |
| Rain enters through a wind-made opening | Homeowners | Interior contents have a stricter test, covered below |
| Storm surge or wave action enters the home | Flood policy only | Excluded from homeowners, even when wind drives it |
| River or creek overflow, rainfall runoff | Flood policy only | Inland flooding is still flood, however far from the coast |
| Sewer or drain backup | Water backup endorsement, if you have one | Separate from flood |
| Your food spoils during the outage | Usually nothing, unless endorsed | See food spoilage and power outage coverage |
The dividing line is not wind versus rain. It is whether the water fell as rain and came in through damage the wind caused, or rose from the sea, a river or the ground as flood.
What the wind coverage does
The ISO HO-3 form (HO 00 03 05 11, hosted by the Maine Bureau of Insurance) insures the house and other structures on an open-perils basis. Wind is not excluded, so hurricane wind damage to the dwelling is covered unless something else in the form excludes it. Personal property works differently: Coverage C is named-perils, and Windstorm or Hail is one of the named perils.
That named peril carries a limitation worth knowing. It does not include damage to property inside a building from rain, snow, sleet, sand or dust unless the direct force of wind or hail first damages the building and creates an opening in the roof or wall through which the rain enters. If a window failed or the roof peeled back, contents damage from the rain that followed is generally covered. If the building was intact and water came in some other way, the contents claim is weaker. Insurers' own forms vary, so read your contract rather than relying on the ISO wording.
Other pieces of the policy matter after a hurricane:
- Reasonable repairs. The form pays the reasonable cost of necessary measures to protect covered property from further damage, such as a roof tarp. Keep the receipts. See reasonable repairs: what you can fix before the adjuster comes.
- Loss of use. If a covered loss makes the home unfit to live in, additional living expenses pay the increase in your living costs for the shortest time needed to repair. The Civil Authority part of the same coverage applies when authorities bar you from the home "as a result of direct damage to neighboring premises by a Peril Insured Against," and the form limits it to two weeks. A precautionary evacuation order with no damage next door may not trigger it under the ISO wording, so ask your agent how your insurer words it. Details are in loss of use and additional living expenses.
- Property removed. Belongings moved out of an endangered home are covered against direct loss from any cause for up to 30 days.
- Ordinance or law. Rebuilding after a hurricane often means meeting current code. The HO-3 adds an amount equal to 10% of the dwelling limit for that, covered in ordinance or law coverage: paying to rebuild to code.
What the flood exclusion says
The HO-3's Section I exclusions bar loss caused by water, defined as "flood, surface water, waves, including tidal wave and tsunami, tides, tidal water, overflow of any body of water, or spray from any of these, all whether or not driven by wind, including storm surge." The words "including storm surge" are in the form. Hurricane wind pushing the sea into a house does not turn flood into wind damage.
The exclusion is also drafted with anti-concurrent causation language: loss is excluded "regardless of any other cause or event contributing concurrently or in any sequence to the loss." Where wind and surge both damaged the same structure, that clause is why insurers separate the two and why some of the sharpest claim disputes in a hurricane happen on this line. The neighboring guides wind vs water: the hurricane claim dispute and anti-concurrent causation clauses explained cover how those fights run.
What a flood policy adds
The NFIP's Standard Flood Insurance Policy defines flood as a general and temporary condition of partial or complete inundation of two or more acres of normally dry land, or of two or more properties, from sources that include "overflow of inland or tidal waters" and "unusual and rapid accumulation or runoff of surface waters from any source" (44 CFR Part 61, Appendix A(1)%20to%20Part%2061)). Storm surge is tidal water, so it qualifies.
Three limits on the NFIP policy shape the decision:
- Dollar limits. For a single-family home, the maximum is $250,000 for the building and $100,000 for contents, according to FEMA's October 2025 Flood Insurance Manual. A home worth far more than that needs excess flood coverage or a private policy.
- A waiting period. New policies and added coverage generally take effect after 30 days, with exceptions such as a loan closing. A policy bought when a storm is already in the forecast will not respond. See the 30-day flood insurance waiting period.
- No wind. The SFIP excludes loss from "wind, or windstorm," so a flood policy never fills a wind gap.
Flood claims do not stay inside mapped flood zones. FEMA reports that nearly one-third of NFIP claims, 29%, from 2014 to 2024 came from outside current high-risk flood areas (FloodSmart). FEMA data compiled by Aon and published by the Insurance Information Institute (as of January 2026) show Hurricane Helene in 2024 generated about 57,800 paid NFIP losses totaling roughly $5.8 billion (III). Whether you hold a policy through the NFIP or a carrier is compared in Private flood insurance vs the NFIP, and the full picture of who needs flood cover is in does homeowners insurance cover flooding?.
A hypothetical storm, claim by claim
Say your dwelling limit is $400,000, your hurricane deductible is 2%, and you carry an NFIP building policy with a $2,000 deductible. A hurricane strips the roof and drops a limb through the garage (covered wind loss of $46,000), and surge floods the ground floor (flood damage to the building of $90,000).
| Piece | Deductible | Roughly what is paid |
|---|---|---|
| Wind damage, $46,000 | 2% of $400,000 = $8,000 | $38,000 from the homeowners insurer |
| Surge damage, $90,000 | $2,000 on the flood policy | $88,000 from the NFIP, subject to its loss settlement rules |
| Same surge damage, no flood policy | none | $0 |
The two deductibles do not offset each other, and the wind payment does not reduce the flood payment. The homeowner without flood cover pays the whole $90,000. These are invented numbers meant to show the structure, not a prediction of what a claim will cost.
Where the wind coverage may be missing
In some coastal places the private market has pulled out of wind coverage, and homeowners buy it somewhere else. Texas's Texas Windstorm Insurance Association writes wind and hail only, not flood or storm surge, in 14 first-tier coastal counties and part of Harris County (TWIA). Alabama, Mississippi, North Carolina, South Carolina and Georgia run similar pools or plans, and Citizens Property Insurance Corporation in Florida writes both wind-only and multiperil policies. In Hawaii, the Insurance Division says hurricane coverage "may be provided through a separate policy or endorsement" (Hawaii Insurance Division). The mechanics, and how a wind-only policy pairs with a homeowners policy that excludes wind, are in windstorm exclusions and wind-only policies. State-level detail is on pages like Florida, Texas and Louisiana, and insuring a coastal home: wind, flood and where to find coverage covers the wider market.
Check your own policy
- Find the hurricane, named-storm or wind/hail deductible on the declarations page. Convert the percentage to dollars using your Coverage A limit.
- Read the wind and flood exclusions in the policy itself and in any state amendatory endorsement. Look for the words "storm surge."
- Confirm whether wind is covered by this policy at all, or by a separate wind-only policy.
- Check for flood cover and its effective date, plus the building and contents limits.
- Ask whether loss of use pays when authorities order an evacuation but your home is not damaged.
- Photograph the home and write down your roof's age and material now, before a storm, using the hurricane and wildfire season insurance checklist.
Key takeaways
- Hurricane wind damage is generally covered by a standard homeowners policy; flood and storm surge, including surge driven by wind, are excluded and need a flood policy.
- The NFIP caps single-family coverage at $250,000 for the building and $100,000 for contents, has a 30-day waiting period in most cases and does not cover wind.
- Wind losses often carry a separate hurricane, named-storm or wind/hail deductible, calculated as a percentage of your dwelling limit.
- Some coastal homes get wind coverage from a state pool or a separate policy, so confirm what your homeowners policy leaves out.
- When a storm causes both wind and surge damage, expect the insurers to allocate the loss between policies, and document everything.
