Here’s a conversation I have every single spring. A homeowner calls after a hailstorm, ready to file a roof claim. I ask what their wind/hail deductible is. There’s a pause, some paper shuffling, and then: “It says 2%. Two percent of what?”
That question — two percent of what? — is worth about ten minutes of your time right now, in calm weather, because the answer decides how much of your next roof you’re paying for yourself.
Why Oklahoma policies have a separate wind/hail deductible
In most of the country, a homeowners policy has one deductible. In hail country, carriers long ago split off wind and hail into their own — usually higher — deductible, because those claims are so frequent here.
How frequent? Per NOAA Storm Prediction Center data published by Triple-I, Oklahoma recorded 369 major hail events (1-inch or larger) in 2025 — the 3rd most of any state. The whole country logged 5,432, meaning one mid-sized state accounted for a strikingly outsized share of the nation’s major hail. That’s the actuarial reality your policy is priced around, and it’s a big part of why, per the most recent NAIC state data, Oklahoma’s average homeowners premium of $2,155 ranks 3rd most expensive in the country.
So the separate deductible isn’t going away. The question is whether yours is set thoughtfully or by default.
The math: percentage deductibles in plain English
A percentage wind/hail deductible is calculated against your Coverage A dwelling limit — the amount your home is insured for — not against the size of the claim and not against your home’s market value.
Take a hypothetical Norman home insured for $300,000:
- 1% wind/hail deductible → you pay the first $3,000 of any wind or hail claim.
- 2% deductible → the first $6,000 is yours.
- 5% deductible → you’re absorbing $15,000 before the carrier pays a dime.
Now put that against what claims actually cost. Per ISO data published by Triple-I, the average US homeowners wind/hail claim runs $13,511, with a frequency of 2.82 claims per 100 insured homes. Hold those two numbers together: with a 5% deductible on that $300,000 home, an average-sized wind/hail claim would pay you almost nothing. You’d have paid premiums for coverage that functionally doesn’t respond until the damage is well above average.
And notice the trap hiding in a good habit: when you raise your dwelling limit to keep up with rebuilding costs — which you absolutely should — a percentage deductible rises right along with it. Homeowners who bumped their Coverage A over the last few years often have a meaningfully bigger deductible than the one they think they chose.
Finding your number (it takes two minutes)
Pull up your declarations page and look for a line reading something like “Wind/Hail Deductible” or “Windstorm or Hail Percentage Deductible.” Then:
- Find your Coverage A dwelling limit.
- Multiply it by the percentage.
- Ask yourself honestly: could I write that check the week after a storm?
If the answer is no, your deductible is set wrong for your finances — no matter how good the premium looks.
Choosing the right deductible: three questions
1. What does the premium savings actually buy you? Moving from a 1% to a 2% deductible lowers your premium, but run the trade both directions: how many years of savings does it take to equal the extra deductible you’d pay in a single hail claim? In a state with 369 major hail events in one year, storms aren’t rare enough to make big deductibles automatically pay off. Sometimes the higher deductible is still the smart move — but only if you’ve done the arithmetic and have the cash reserves to back it.
2. How old is your roof? A percentage deductible interacts badly with an aging roof, especially on policies that pay actual cash value on roofs. Depreciation comes off the top, then your deductible comes off — and the check that’s left can be a fraction of the replacement cost. If your roof is past its mid-teens, this combination deserves a hard look. Our archive piece on hail damage and roof claims walks through how these claims actually get adjusted.
3. Flat or percentage? Some carriers in Oklahoma still offer flat-dollar wind/hail deductibles, or lower percentage options, and the differences between carriers here are bigger than almost anywhere else on the policy. This is exactly the comparison an independent agent exists to make.
Deductible strategy is carrier strategy
Two policies with identical premiums can behave completely differently after a storm — one with a 1% deductible and replacement cost on the roof, the other with 2% and a roof payment schedule. Price-shopping without reading the deductible page is how homeowners end up disappointed in May.
When we quote a home across our 22 carriers, we put the wind/hail deductible math on the table in dollars, not percentages, right next to the premium. That’s the only honest way to compare.
