Percentage Wind and Hail Deductibles: The Math Most Ohio Homeowners Miss
You believe your deductible is a thousand dollars. For hail, it may be two per cent of your dwelling coverage — a different number entirely, and one that grows every year without anyone telling you.

Two Deductibles on One Policy
Many Ohio homeowners policies now carry a separate deductible for wind and hail losses, distinct from the all-other-perils deductible on the front of the declarations page.
The all-other-perils figure is usually a flat dollar amount. The wind and hail figure is often a percentage — typically one, two, or five per cent — and the percentage is applied to your dwelling coverage limit, not to the size of the loss.
Working Out Your Real Number
Find Coverage A on your declarations page. That is the dwelling limit. Multiply it by the wind and hail percentage.
- Coverage A of $400,000 at 1% gives a $4,000 deductible.
- Coverage A of $400,000 at 2% gives an $8,000 deductible.
- Coverage A of $650,000 at 2% gives a $13,000 deductible.
Now apply it. A $16,000 hail claim with a flat $1,000 deductible pays roughly $15,000 before depreciation. The same claim with a 2% deductible on $400,000 of dwelling coverage pays roughly $8,000. Same damage, same carrier, eight thousand dollars of difference from one line on the declarations page.
The part that compounds
Most policies carry an inflation guard that raises Coverage A automatically at each renewal to keep pace with construction costs. A percentage deductible rises with it. Your dwelling limit going from $400,000 to $440,000 quietly moves a 2% deductible from $8,000 to $8,800 — and nothing in the renewal packet announces that.
What triggers it
Read the definition. Some endorsements apply the percentage deductible to hail only, some to wind and hail together, and some to any loss during a named storm event. On a claim involving both wind-driven rain and hail, which deductible applies can be a real question.

Three Things to Do Before Spring
First, locate both deductibles on your declarations page and write down the actual dollar figure for the wind and hail one. Do it once a year at renewal, because the number moves.
Second, ask your agent what the premium looks like with a flat deductible instead, and with different percentage tiers. Sometimes the saving from a percentage deductible is small enough that it is not worth the exposure. Third, if you keep the percentage deductible, know the number and plan for it — that is the amount you need available if a spring storm comes through.
Why This Shows Up Across Central Ohio
Central Ohio gets hail in clusters through spring and early summer. Carriers responded to a run of heavy loss years by adjusting terms rather than only prices, and percentage wind and hail deductibles spread across the market as part of that adjustment.
The consequence is that the arithmetic on a marginal claim has shifted. A repair that would have cleared a $1,000 deductible comfortably may not clear an $8,000 one, which changes whether filing makes sense at all. That is a reason to know the number before storm season rather than during a claim.

Inflation guard provisions raise your dwelling limit at renewal, and a percentage deductible rises with it automatically. The percentage stayed the same; the base it applies to did not.
Often yes, usually for a higher premium and typically at renewal. Ask your agent for quotes at several options so you can compare the trade-off directly.
