The honest answer is "half of it" — and which half depends entirely on whether the damage came from wind or from water. That single distinction decided whether thousands of Long Island families were made whole after Superstorm Sandy, and it still decides claims today. On top of it sits a second layer most homeowners have never read: the hurricane deductible, which New York just standardized statewide in February 2026. Here's exactly what your policy pays after a storm, what it never pays, when the bigger deductible kicks in, and what to do in the days after damage.
Does home insurance cover hurricane damage on Long Island?
Partly. A standard Long Island homeowners policy covers hurricane wind damage — roof, windows, fallen trees, and rain entering through wind-created openings — but never covers flooding or storm surge, which require a separate flood insurance policy.
- Wind: covered. Torn shingles, broken windows, a tree through the roof, and the rain that follows the wind in.
- Water from outside: not covered. Storm surge, bay overwash, and rising water are flood — excluded from every homeowners policy.
- Your deductible changes. When a hurricane triggers it, a 1–5% hurricane deductible replaces your flat one — $10,000–$25,000 on a $500K home.
- New for 2026: New York now uses one uniform hurricane definition — 74+ mph sustained winds with landfall in New York State.
- A nor'easter never triggers it. Nor'easter wind damage is covered under your standard deductible instead.

Wind vs. water: the line that decides your claim
Your homeowners policy covers hurricane damage caused by wind and excludes damage caused by water that rises from outside — and a single storm routinely does both. Understanding which side of that line your damage falls on is the whole ballgame after a hurricane.
Wind is a covered peril. If a hurricane strips shingles, blows out windows, drops a tree on your roof, or tears siding off the house, that's your homeowners policy's job. It also covers what insurers call "resulting damage" — if the wind opens a hole and rain pours through it, the water damage inside follows the covered wind loss and is generally paid.
Water that comes from outside and rises is a different story. Storm surge, bay overwash, a swollen creek, and street flooding are all flood, and flood is excluded from every standard homeowners policy in America. It doesn't matter that a hurricane caused it. That's why so many Long Island homeowners with excellent coverage got nothing for their first floors after Sandy — the exclusion isn't about the storm, it's about the water's path.
| Hurricane damage | Covered by homeowners? | What pays |
|---|---|---|
| Roof shingles torn off | ✅ Yes | Homeowners (hurricane deductible applies) |
| Windows blown out | ✅ Yes | Homeowners |
| Tree falls on the house | ✅ Yes | Homeowners, debris removal typically included |
| Rain through a wind-made hole | ✅ Yes | Homeowners — resulting damage from a covered peril |
| Detached garage or fence destroyed | ✅ Yes | Homeowners, other-structures coverage (~10%) |
| Spoiled food after a long outage | ⚠️ Sometimes | Often covered up to a small sub-limit — check your policy |
| Storm surge floods the first floor | ⛔ No | Flood policy only (NFIP or private) |
| Bay or creek overflows into the basement | ⛔ No | Flood policy only |
| Sewer backs up during the storm | ⛔ Not standard | Only with a sewer-backup endorsement |
How hurricane damage resolves under a standard Long Island homeowners policy. Individual policies vary — check your declarations page for your specific deductibles and endorsements.
After a coastal storm, the central question in a claim is usually "did wind or water do this?" — because the answer determines which policy pays, and whether anything pays at all. That's why photographing damage before you clean up matters so much: it preserves the evidence of what happened first.
How does a hurricane deductible work?
A hurricane deductible is a percentage of your dwelling coverage — commonly 1% to 5% — that replaces your flat standard deductible when a hurricane damages your home. It's not an extra charge; it's a much larger amount you absorb before coverage begins, and it's the reason two policies with identical premiums can leave you in very different places after a storm.
The math is simple and unforgiving. New York's Department of Financial Services gives this example: a home insured for $150,000 with a mandatory 5% hurricane deductible leaves the owner responsible for the first $7,500 of hurricane loss. Scale that to Long Island values and the numbers get serious fast.
| Dwelling coverage | 1% deductible | 2% deductible | 5% deductible |
|---|---|---|---|
| $300,000 | $3,000 | $6,000 | $15,000 |
| $500,000 | $5,000 | $10,000 | $25,000 |
| $750,000 | $7,500 | $15,000 | $37,500 |
| $1,000,000 | $10,000 | $20,000 | $50,000 |
What a hurricane deductible costs you out of pocket at common Long Island dwelling limits. The percentage applies to your Coverage A limit, not to the size of the claim.
Two details people miss. First, the percentage applies to your dwelling limit, not to the damage amount — so a $12,000 roof claim on a $500,000 home with a 5% deductible pays nothing at all, because your share is $25,000. Second, under New York's rules the hurricane deductible applies to your total loss across all affected coverage parts, so it isn't charged separately against your house, your other structures, and your belongings.
What changed in New York in February 2026?
On February 2, 2026, New York adopted a single uniform definition of "hurricane" for deductible purposes, replacing more than 100 different carrier-specific definitions that had been approved over the years. For Long Island homeowners, this is the most consumer-friendly change to storm coverage in years, and it's worth knowing exactly what it did.
Under the amended regulation (the Third Amendment to 11 NYCRR 74, Insurance Regulation 159), a hurricane is now defined statewide as a tropical cyclone with maximum sustained surface winds of 74 mph or higher, as determined by the National Weather Service or a similar meteorological entity. More importantly, the rule sets hard limits on when the deductible can apply:
- Landfall required. A hurricane deductible can only be triggered after a hurricane makes landfall in New York State — not a near-miss, not a storm that stays offshore.
- A defined time window. It applies only to wind damage occurring from 12 hours before landfall until 12 hours after the last hurricane watch or warning for the state is cancelled.
- Clear disclosure. Carriers must spell out the hurricane category that triggers the deductible and state the time-window rule in your policy.
- One deductible per event. It applies to your total losses across all affected coverage parts.
There's a flip side worth knowing too. Historically, carriers could only request hurricane deductibles for properties in Nassau, Suffolk, Westchester, and four New York City boroughs. As of February 2, 2026, insurers may ask DFS to apply hurricane deductibles to property anywhere in New York State — a meaningful expansion, even though the trigger rules themselves are now tighter and clearer. If you own property outside the traditional coastal zone, it's worth checking whether a hurricane deductible has appeared on your renewal.
Does a nor'easter trigger the same deductible?
No — a nor'easter cannot trigger a hurricane deductible, because it isn't a tropical cyclone making landfall with 74+ mph sustained winds. Nor'easter wind damage is still covered by your standard homeowners policy; it's just subject to your ordinary flat deductible instead of the percentage one.
That's genuinely good news on Long Island, where nor'easters do real damage nearly every winter without ever meeting the hurricane definition. A March nor'easter that takes half your shingles is a normal wind claim with, say, a $1,000 deductible — not a $10,000 one.
One caveat: some policies carry a separate windstorm deductible, which is optional in New York and applies to any windstorm loss, commonly 1% to 5% of your dwelling value. If you have one of those, a nor'easter could indeed hit a percentage deductible. It's a different line item from the hurricane deductible, and it's worth checking whether you're carrying one — some homeowners accepted it years ago for a premium break and forgot.
Do you need flood insurance on Long Island?
If you own a home on Long Island, flood insurance is the only thing that covers storm surge and rising water — and about 34% of Long Island properties carry meaningful flood risk over the next 30 years. Your homeowners policy will never fill that gap, no matter how good it is.
Flood coverage comes from two places: the National Flood Insurance Program (NFIP), the federal program available through participating carriers and agents, or a private flood carrier, which sometimes offers higher limits or broader terms. Which makes sense depends on your flood zone, elevation, and how much coverage you need.
The detail that catches people: NFIP policies typically carry a 30-day waiting period before coverage begins. You cannot buy flood insurance when a storm is named and expect it to help — the decision has to be made months ahead, which is exactly why mid-summer is the right time to look at it. Being outside a mapped high-risk zone doesn't mean you're safe, either; plenty of Sandy-era flood claims came from homes that had never flooded before.
What discounts are required for storm protection?
New York law requires insurers to offer a discount to any homeowner who installs storm shutters or hurricane-resistant laminated glass windows and doors. That credit is mandated, not optional — and many carriers offer additional savings beyond it for other wind-mitigation work.
- Storm shutters or impact-rated glass — the state-mandated discount, and the most direct way to lower a coastal premium.
- Roof tie-downs and reinforced roof decking — help keep the roof attached, which is what most hurricane claims are about.
- Impact-rated garage doors — a common failure point that can lead to catastrophic pressurization damage.
- A newer roof — often earns a credit on its own and widens the set of carriers willing to write the home.
These upgrades do double duty: they lower your premium, and they reduce the odds you'll ever have to eat a percentage-based hurricane deductible. If you've already done any of this work — new roof, new impact windows, shutters in the garage — make sure your agent has documentation, because uncredited mitigation is money left on the table. That's part of the annual review we run for clients.
What should you do after storm damage?
Document everything before you clean up anything — the photographs you take in the first hour are what separate a smooth claim from a disputed one. Here's the sequence that protects you.
1. Make sure everyone is safe. Stay away from downed power lines, standing water, and anything structurally questionable. Nothing on this list matters more than that.
2. Document before you touch. Photograph and video everything from multiple angles, inside and out, before moving or discarding a single item. Capture the whole roofline, every affected room, and any water lines on walls.
3. Make reasonable temporary repairs. Tarp the roof, board the windows, stop further damage — and keep every receipt. Those costs are typically reimbursable, and preventing additional damage is your responsibility under the policy.
4. Report the claim promptly. Call your agent or carrier as soon as you can. Describe wind damage and water damage separately, because they may fall under two different policies.
5. Track your deductible and living costs. Confirm whether the hurricane deductible was actually triggered under the landfall and time-window rules — and if your home is unlivable, save hotel and meal receipts for loss-of-use coverage.
One more thing worth saying plainly: after a major storm, contractors appear quickly and not all of them are legitimate. Be cautious with anyone demanding large deposits or pressuring you to sign over your claim.

Frequently asked questions
Does home insurance cover hurricane damage on Long Island?
Partly. A standard Long Island homeowners policy covers hurricane wind damage — a torn-off roof, broken windows, a fallen tree, and the rain that gets in through that wind-created opening. It does not cover flooding or storm surge, which are excluded from every standard homeowners policy and require separate flood insurance. So in a hurricane that brings both wind and water, your homeowners policy handles one half of the damage and a flood policy handles the other. When wind damage is covered, your hurricane deductible applies instead of your standard deductible.
What is a hurricane deductible in New York?
A hurricane deductible is a separate percentage-based deductible — typically 1% to 5% of your dwelling coverage — that replaces your flat standard deductible when a hurricane damages your home. On a $500,000 Long Island home, a 2% hurricane deductible means you pay the first $10,000 of wind damage yourself, and at 5% it's $25,000. Under New York regulations effective February 2, 2026, a hurricane deductible can only be triggered after a hurricane makes landfall in New York State, and it applies only to wind damage occurring from 12 hours before landfall until 12 hours after the last hurricane watch or warning is cancelled.
Does a hurricane deductible apply to a nor'easter?
No. A nor'easter is not a hurricane, so a hurricane deductible cannot be triggered by one under New York's rules — a hurricane deductible requires a tropical cyclone with sustained winds of at least 74 mph that makes landfall in New York State. Nor'easter wind damage is still covered by your standard homeowners policy, but it's subject to your ordinary flat deductible, or to a separate windstorm deductible if you chose to carry one. That distinction matters on Long Island, where nor'easters cause significant wind damage every year without ever meeting the hurricane definition.
Is storm surge covered by homeowners insurance?
No. Storm surge is flooding, and flooding is excluded from every standard homeowners insurance policy regardless of what caused it. If ocean or bay water pushes into your home during a hurricane, only a separate flood insurance policy — through the National Flood Insurance Program or a private flood carrier — will pay for that damage. This was the single most painful lesson of Superstorm Sandy for thousands of Long Island households who had excellent homeowners coverage and no flood policy. Flood policies also typically carry a 30-day waiting period, so they must be purchased well before a storm.
Are there discounts for hurricane shutters in New York?
Yes. New York law requires insurers to offer a discount to any homeowner who has installed storm shutters or hurricane-resistant laminated glass windows and doors. Beyond that mandated credit, many carriers offer additional savings for roof tie-downs, impact-rated garage doors, reinforced roof decking, and other wind-mitigation improvements. These upgrades do double duty on Long Island: they lower your premium and they reduce the chance you ever have to pay a percentage-based hurricane deductible in the first place. Ask your agent to document any mitigation work you've already done.
Does insurance cover a tree falling on my house? Yes — the damage to your home and typically debris removal are covered, though removing a tree that fell harmlessly in the yard usually isn't.
Is spoiled food covered after a hurricane outage? Many policies include a small food-spoilage sub-limit for power loss; amounts are modest, so check your declarations page.
Does my policy cover a hotel if the house is unlivable? Yes — loss-of-use coverage, typically around 20% of your dwelling limit, reimburses additional living expenses after a covered loss.
Can my carrier drop me after a hurricane claim? A single weather claim doesn't automatically mean non-renewal, but repeated claims can affect renewal decisions and carrier appetite.
What if I can't find coverage on the coast? New York's FAIR Plan and the Coastal Market Assistance Plan (C-MAP) exist specifically to help coastal homeowners who can't secure coverage in the standard market.
The bottom line on hurricane coverage for Long Island homes
Your homeowners policy covers hurricane wind damage and never covers storm surge or rising water. That one line decides most coastal claims, and the only way to cover the other half is a separate flood policy bought at least 30 days ahead. Layered on top is the hurricane deductible — 1% to 5% of your dwelling coverage, which on a $500,000 Long Island home means $5,000 to $25,000 out of pocket before anything gets paid.
New York's February 2026 reform genuinely helps: one statewide definition, a 74 mph threshold, an actual landfall requirement, and a defined 12-hour window. Nor'easters can't trigger it at all. What's left for you to do is straightforward — know your hurricane deductible percentage, confirm whether you also carry an optional windstorm deductible, decide on flood coverage before the season peaks, and make sure every bit of storm mitigation you've done is documented and credited.
