Hurricane Deductibles Explained: The Number Most Long Island Homeowners Get Wrong
Last reviewed: July 2026
TL;DR
A hurricane deductible is a percentage of your dwelling coverage, not a flat dollar amount and not a percentage of the claim. On a $600,000 Long Island home with a 5% hurricane deductible, you absorb the first $30,000 of wind damage from a qualifying storm. Since February 2026, New York uses one uniform trigger: a hurricane making landfall in the state, with a damage window that opens 12 hours before landfall and closes 12 hours after the last watch or warning is canceled. Know your percentage and your dollar exposure before storm season, not after.

Two deductibles, one policy
Most Long Island homeowners policies carry two deductibles. The first is the flat all-peril deductible you chose, often $500 to $2,500. It applies to a kitchen fire, a burst pipe, a tree through the garage in a regular storm.
The second is the hurricane deductible. It replaces the flat deductible when a qualifying hurricane causes wind damage. Instead of a fixed dollar amount, it is a percentage of your Coverage A dwelling limit, typically 1% to 5% in New York.
The percentage is applied to your coverage limit, not to the size of the claim. This is the part homeowners most often get wrong, and it is why a hurricane deductible can turn a covered loss into a five-figure out-of-pocket event.
The math, in dollars
Find your Coverage A limit on your declarations page, then find your hurricane deductible percentage. Multiply. That number is your share of any qualifying wind claim before the insurer pays anything.
| Dwelling coverage (Coverage A) | 2% deductible | 5% deductible |
|---|---|---|
| $400,000 | $8,000 | $20,000 |
| $600,000 | $12,000 | $30,000 |
| $800,000 | $16,000 | $40,000 |
| $1,000,000 | $20,000 | $50,000 |
Two things make this worse over time. Construction cost inflation has pushed Coverage A limits up at renewal, which raises the dollar value of the same percentage. And some carriers writing coastal ZIP codes have moved toward the higher end of the percentage range. A homeowner who had a 2% deductible on a $450,000 limit in 2019 may now have 5% on $650,000. That is a jump from $9,000 to $32,500 in exposure without a single policy decision by the homeowner.
If the storm does not meet the hurricane trigger, the hurricane deductible does not apply and your flat deductible governs the claim. That difference alone can be worth tens of thousands of dollars, which is why trigger language matters.
What triggers a hurricane deductible
New York standardized the trigger in a regulation that took effect on February 2, 2026 (11 NYCRR 74). Before that, each carrier filed its own trigger with the Department of Financial Services, and the same storm could trigger one neighbor's deductible and not another's. Under the current rule, the pieces are:
Landfall in New York
The deductible applies only when the designated meteorological entity determines a hurricane made landfall in the state
12 hours before landfall
The window for qualifying wind damage opens 12 hours before the hurricane makes landfall in New York
12 hours after the last warning
The window closes 12 hours after the last hurricane watch or warning is canceled
Wind damage only
The deductible applies to wind losses in that window; flood and storm surge are separate policies entirely
The practical consequence: whether the deductible applies to your claim now turns on the storm's official landfall determination and timing, not on which carrier wrote your policy. Carriers still decide which counties and coastal distances carry a hurricane deductible at all, and at what percentage, so two neighbors can still have very different exposure amounts.
Find your deductible in your policy's windstorm or hurricane deductible endorsement, and note that documents issued before February 2026 may describe an older trigger. The New York DFS explains how these deductibles work and requires the deductible to be shown as a dollar amount on your declarations page. If you cannot locate yours, ask your agent to point to the exact policy language in writing.
The hurricane deductible covers wind, not water
A hurricane deductible applies to wind damage: roof and siding loss, broken windows, trees down, rain that enters through an opening the wind created. It has nothing to do with flooding, because your homeowners policy excludes flood entirely.
Storm surge, the deadliest and most destructive part of a Long Island hurricane, is flood. When Sandy pushed the Atlantic into south shore living rooms in 2012, homeowners policies paid nothing for that water regardless of any deductible. Flood coverage is a separate policy with its own deductible, covered in our Long Island flood insurance guide.
A single hurricane can therefore produce two claims under two policies with two deductibles: a wind claim on your homeowners policy subject to the hurricane deductible, and a flood claim on your NFIP or private flood policy. Budget for that scenario, not just one or the other.
How to manage the exposure
Calculate your number today.
Coverage A limit times deductible percentage. Write it down. If that number would be hard to cover after a storm, raise the issue with your agent before renewal.
Read your current policy documents.
New York standardized the hurricane trigger in February 2026, so paperwork issued before then may describe rules that no longer apply. Confirm your deductible percentage and its dollar amount on your latest declarations page.
Ask about lower percentage options at renewal.
Some carriers offer 1% or 2% instead of 5% for a higher premium. Get the price difference in dollars and compare it against the reduction in your exposure.
Ask about mitigation credits.
Storm shutters, impact-rated glass, roof tie-downs, and a newer roof can earn premium credits with some carriers and make your property easier to place. Get any promised credit confirmed in writing.
Hold a dedicated reserve.
Treat your hurricane deductible like a known liability. An emergency fund that covers it means a storm damages your house, not your solvency.
