In wind- or hail-prone regions, many homeowners policies swap the usual flat-dollar deductible for a percentage-based one specifically for storm claims — often a bigger out-of-pocket cost than homeowners expect.
How it works
Multiplying dwelling coverage by the wind/hail deductible percentage gives the dollar deductible that applies specifically to a wind or hail claim, separate from the policy’s standard deductible for other claim types.
What this does not include
This does not include state-specific rules — some states require insurers to offer a flat-dollar alternative, and coastal states often have separate, even higher named-storm or hurricane deductibles on top of a general wind/hail percentage deductible.

Frequently asked questions
Why would an insurer use a percentage instead of a flat dollar deductible?
It scales the insurer’s exposure with the size of the home and its coverage, which matters especially for catastrophic wind events that can affect many policies in a region simultaneously.
Does this deductible apply to every homeowners claim?
No — typically only to wind and hail claims specifically; other covered perils (fire, theft, water damage) usually still use the policy’s standard flat-dollar deductible.
Can I negotiate or choose a lower percentage?
Sometimes — insurers often offer a choice of percentage tiers, with a lower percentage deductible generally costing a higher premium.
