Storm Surge vs Wind
Wind damage is covered under standard home insurance. Storm surge is flooding, covered only by a separate flood policy.
Free to compare
Wind tears shingles off a roof, snaps a tree onto the house, or blows out windows, and your homeowners policy pays for that, minus your deductible. Water pushed in from the ocean or a swollen bay is storm surge, and that falls under flood insurance, a separate policy bought ahead of time. Most hurricanes cause both kinds of damage at once. Adjusters look at the waterline and the wind patterns to work out which policy pays for which part of the loss.
If your house sits near the coast and you've never priced flood insurance alongside your homeowners policy, you're carrying a gap that only shows up after the water recedes. A hurricane that knocks a tree onto your roof and pushes storm surge through your first floor means two separate claims and two deductibles. Comparing coverage now shows where that gap sits before a storm finds it.
What if the adjuster can't tell wind from water damage?
A lot of hurricane claims run into this problem. A house can lose its roof to wind, then take on storm surge an hour later, and by the time anyone inspects it, the damage is mixed together. Insurers send adjusters trained to read the physical evidence. A waterline stain across the drywall, mud inside the walls, or a car moved across a lawn points to surge. Shingles stripped in one direction, a tree down on the roof, or a chimney knocked sideways points to wind. Photos and video from before the storm help, and so does anything taken during it, if you have it.
Many coastal states use a legal rule called the anti-concurrent causation clause, written into most homeowners and flood policies. If a loss involves both an excluded cause and a covered one, like storm surge and wind, the exclusion wins unless you can show the wind alone would have caused the damage. This is why documentation matters so much. A roof that wind tore off before the surge arrived is a wind claim even if the house later floods. A wall that stood through the wind and then failed under the weight of water is a flood claim. Where the two overlap, insurers and flood adjusters sometimes disagree, and that disagreement becomes the claim.
Filing both claims at once, rather than waiting to see which one gets denied, is the more reliable way through this. A homeowners claim and a flood claim run on different timelines, with different adjusters and different paperwork. Opening both early means neither one stalls while you wait on the other. Keep receipts for any temporary repairs. Note the time you noticed each kind of damage if you can, and ask each adjuster directly what they attributed the damage to and why. That answer is usually in the claim file even if it is not said out loud.
If the two claims don't add up to the full cost of repair, the gap is sometimes a coverage limit rather than a coverage dispute. Flood policies through the federal program cap dwelling coverage at a fixed amount regardless of what the house is actually worth to rebuild. Homeowners dwelling limits are set by what you chose when you bought the policy. Checking both limits against current rebuilding costs before storm season, not after a claim, is the only way to know ahead of time whether this gap exists on your own house.
How does the hurricane deductible work, separately from all this?
A hurricane deductible is not the same as the flat dollar deductible that applies to most other claims on your policy. It only applies in certain states, mostly along the Gulf and Atlantic coasts. Instead of a fixed number, it's a percentage of your dwelling coverage, usually somewhere between 1 and 5 percent, and your declarations page states the exact figure for your policy. If your house is insured for 300,000 dollars and your hurricane deductible is 2 percent, you're paying the first 6,000 dollars of any hurricane-related claim before your insurer pays anything.
What triggers this deductible varies by state and by insurer. Some policies apply it to any storm that's been named by the National Hurricane Center, whether or not it made landfall as a hurricane near you. Others only apply it once wind speeds in your area hit a certain threshold, or once the storm is officially declared a hurricane at landfall. A tropical storm that causes real damage might fall under your regular wind deductible instead of the hurricane one, and that matters because the regular deductible is usually a smaller, flat amount. The trigger language is written into your policy, not standardized across the industry, so two neighbors with different insurers can end up with different deductibles for the same storm.
A hurricane deductible is separate from your flood deductible, which is its own fixed number set by the flood policy. A hurricane that causes both wind and storm surge damage can mean paying two deductibles, one calculated as a percentage for the wind claim and one flat amount for the flood claim, before either policy starts covering repairs. Knowing both numbers ahead of a storm, not after one hits, is the only way to know what a bad storm actually costs out of pocket.
Some states require insurers to offer a buy-back option, lowering the hurricane deductible back to a flat dollar amount for an added premium. Whether that's worth it depends on how exposed your house is and what you could absorb if a bad season hit. Either way, the number on your declarations page is the one that governs your claim, not whatever your neighbor's policy says or what a past storm cost someone else.
