Why is my wind and hail deductible a percentage instead of a dollar amount?
Because in wind-exposed territory insurers stopped selling a flat deductible for that peril. A percentage deductible is calculated on the insured value of the building rather than on the size of the claim, so 2% of a $5 million building is a $100,000 deductible whether the damage is $120,000 or $4 million. Owners read the percentage as small and it is not, and in the hardest markets the alternative is worse, because the policy excludes wind and hail entirely and the peril has to be bought somewhere else.

The detail
A percentage wind, hail or hurricane deductible is applied to the insured value of the property rather than to the amount of the loss, so the dollar figure scales with the building limit and not with the damage.
Standard commercial property wording; confirmed against carrier forms
Texas maintains a residual windstorm market, the Texas Windstorm Insurance Association, for designated coastal counties where the standard market will not write the peril.
What this means for you
- Work out the deductible in dollars before you buy, not after a storm. Multiply the percentage by the building limit. The number surprises people every time.
- Read the trigger, not just the percentage. A named-storm deductible applies only to a declared, named system; a wind and hail deductible applies to any windstorm, including an ordinary thunderstorm that takes off part of a roof.
- Check whether wind is on the policy at all. In hard coastal markets it is stripped out and placed separately or through a state pool, and an owner who has not read the exclusions can believe they are covered for the one peril they are not.
- A percentage deductible is a financing problem, not just an insurance one. Know where the cash comes from before you need it, because the lender will still expect the building repaired.

Related questions
- What is the difference between a named storm and a wind/hail deductible?
The trigger. A named storm deductible bites only when the loss is caused by a system a weather authority has formally named, so it does not apply to a summer hailstorm or a straight-line wind event, which fall under the ordinary deductible. A wind and hail deductible applies to any wind or hail loss whatever its origin. The named storm version is narrower and therefore better for the insured, and the two get used interchangeably in conversation when they are not the same thing.
- Can I buy wind coverage back if my policy excludes it?
Usually, and it is a separate placement rather than an endorsement. Depending on the state that means a standalone wind and hail policy, a surplus lines placement, or a residual market pool such as the Texas Windstorm Insurance Association or a state beach plan. Budget for the property as a package of policies rather than one, and confirm the wind placement is actually bound: a gap here is a total loss on the peril the location is most exposed to.
- How does roof age affect this?
More than almost anything else in wind territory. An older roof can move you from replacement cost to actual cash value settlement on the roof specifically — a schedule that depreciates it by age — or attract a separate, higher wind deductible, or lose you the market altogether. A roof replacement is the single most effective thing an owner in a wind or hail state can do to their insurance, and the year it was done is a question on every submission.

- Does flood come into this?
It is separate, and the distinction matters after every hurricane. Wind coverage responds to wind-driven damage; rising water is flood and is excluded from essentially every property policy. Storm surge is flood, not wind, which is the argument that follows coastal events. If the property can take water, the flood policy is a different purchase and needs making deliberately.

Need this handled?
Reading about it and having it handled are different jobs, and the second one is ours. We place the accounts other brokers decline — claims history, a cancellation, an unusual operation, a business nobody wants to underwrite twice — and we will tell you when the policy you already have is the right one. Tell us the situation and a licensed human replies the same business day.
