Storm deductible guide

    How Does a Percentage Hurricane or Wind Deductible Work?

    Live in a coastal or high-wind area? Your storm deductible may be a percentage, and it is not a percentage of the repair bill.

    The short version

    • In many coastal and high-wind areas, the storm deductible is a percentage of the amount the house is insured for, not of the damage.
    • On a house insured for $450,000, a 2% storm deductible is $9,000 out of pocket before the policy pays, whether the repair is $20,000 or $120,000.
    • Hurricane, named-storm, and wind deductibles have different triggers. Flood is a separate policy altogether.

    Why isn't my storm deductible a flat number?

    A percentage storm deductible is a percentage of your dwelling limit, also called Coverage A, not a percentage of the damage. With a 2% deductible on a home insured for $350,000, you pay the first $7,000 of a covered storm loss.

    These deductibles are common in coastal and high-wind areas. Whether a hurricane, a named storm, or any wind or hail sets one off depends on the policy and the state.

    Say the policy says the house is insured for $450,000 and the storm deductible is 2%. What you pay first is:

    $450,000
    house insured for
    2%
    deductible rate
    $9,000
    what you pay first
    What you pay first: flat deductible vs. 2% of a $450,000 house

    That $9,000 is tied to the insured amount for the house. It is not 2% of the repair bill. A $20,000 roof job with a 2% storm deductible on a $450,000 house still means $9,000 out of pocket first, when that deductible applies, not $400.

    Percentage storm deductibles commonly run from 1% to 5%, depending on the policy and the state. Exact wording and triggers vary by insurer and by endorsement.

    Hurricane, named storm, or wind: which one is mine?

    These are related ideas, but they are not the same label, and the label decides when the bigger deductible kicks in.

    1. Hurricane deductible. Often applies when a hurricane causes the loss, as the policy defines it or as a weather authority the policy points to declares it. The policy says when the hurricane window starts and ends, and that definition controls whether the percentage applies.
    2. Named-storm deductible. Often applies when a named storm causes the loss, meaning a tropical storm or hurricane that receives an official name. This can apply in situations a hurricane-only deductible would not, because not every named storm becomes a hurricane.
    3. Wind or windstorm deductible. Some policies skip the hurricane and named-storm labels and apply the percentage to any wind loss, or to wind losses during a certain season.

    Some policies use one of these. Some use two. The declarations page and the deductible section of the policy are where the trigger is spelled out. If the wording is unclear, that is a question for a licensed agent.

    Good to know: The trigger matters as much as the percentage. A 2% named-storm deductible can apply to a tropical storm that never became a hurricane. A 2% hurricane deductible might not.

    Does my storm deductible have anything to do with flood?

    No. A wind or hurricane deductible on a homeowners policy is about wind, and the storm damage the homeowners policy addresses.

    Flood is a separate question. Standard homeowners policies commonly do not cover flood at all. Flood coverage, when someone has it, usually comes through a separate policy, either through the National Flood Insurance Program (NFIP) or a private flood insurer.

    One more thing about NFIP flood insurance: it typically has a 30-day waiting period before coverage starts, with some exceptions, such as a new loan closing or a flood-map change. That waiting period is about when flood coverage begins. It has nothing to do with the percentage deductible on your homeowners policy.

    Where do I find my number?

    Your declarations page. It is the one- or two-page summary at the front of your policy: limits, deductibles, and key endorsements in one place.

    1. Find the dwelling amount. That is what the policy says the house is insured for.
    2. Find the deductible line. Look for a line labeled storm, hurricane, named storm, or wind, and check whether it shows a flat dollar amount or a percentage.
    3. Do the math. If it is a percentage, multiply it by the dwelling amount, the same way as $450,000 × 2% = $9,000 above.
    4. Find the trigger. Hurricane, named storm, or wind, and where in the policy that term is defined.

    Not sure which line is which? Our guide to reading the declarations page walks through it.

    Questions you may want to ask your agent

    • Is my storm deductible a flat dollar amount or a percentage of what the house is insured for?
    • Does it trigger for hurricane, named storm, or wind, and where is that defined in my policy?
    • If it is a percentage, what dollar amount does that come to today?
    • Do I have flood coverage? If not, what would a separate flood policy involve?
