Your Deductible Might Not Be a Dollar Amount. Run the Math Before the First Storm.

Your policy's declarations page lists a deductible, and for a growing number of homeowners it is not a dollar figure. It is a percentage of your dwelling limit, and on a $700,000 home a 2% deductible means the first $14,000 of a wind or hail loss is yours. Most roof claims never clear that bar.

That is not a trick. Percentage deductibles are part of how coverage stays available and affordably priced in storm-exposed areas. The gap is that the trade gets made quietly at renewal, and most people find out what they agreed to after the storm. Here is how to find out now.

Flat, percentage, and split: which one do you have?

Open your declarations page, the summary at the front of the policy. Look for the word "deductible" and read every line, not just the first one.

A flat deductible is a dollar amount, like $1,000 or $2,500, and it applies to most claims. A percentage deductible reads something like "Wind/Hail: 2%." A split structure has a flat number for things like fire and theft, plus a separate percentage for wind, hail, or named storms.

Here is what most people don't know: many policies show the flat number most prominently, with the percentage in a smaller endorsement further down. If you see the words "windstorm or hail," "named storm," or "hurricane" anywhere near a percent sign, you have a split structure. Your agent can confirm it in one email.

The percentage applies to your dwelling limit, not your home's value

The percentage is calculated on Coverage A, the dwelling limit on your policy. It is not calculated on the market value of your house, your mortgage balance, or the damage itself. New York's Department of Financial Services uses the standard example: a $300,000 dwelling limit with a 5% deductible means a $15,000 deductible.

This matters in two ways. First, if your dwelling limit went up at renewal because rebuilding costs rose, your deductible went up with it, even though you changed nothing. Second, the number on your policy is the number that counts. A house that would sell for $1.4 million but carries a $700,000 rebuild limit has a deductible based on $700,000.

The arithmetic, at three home sizes

Run your own numbers before a storm does. Multiply your Coverage A limit by the percentage:

• $400,000 dwelling limit: 1% is $4,000, 2% is $8,000, 5% is $20,000.
• $700,000 dwelling limit: 1% is $7,000, 2% is $14,000, 5% is $35,000.
• $1,200,000 dwelling limit: 1% is $12,000, 2% is $24,000, 5% is $60,000.

Compare those figures to a typical loss. A roof repair after hail, a section of siding, or a few fences often costs less than $14,000 on its own. At that point the policy still exists, but it pays nothing on the claim. Write the dollar figure for your house on a sticky note and keep it with your policy.

When two deductibles can apply at once

Split structures create a second question: which deductible applies to which event? Wind and hail often carry their own percentage. Named storms and hurricanes carry another, and it is usually triggered by a formal weather-service declaration and a time window around landfall. Winter storm damage may fall under the standard deductible or a separate one, depending on your state and your carrier.

A single storm can also do different kinds of damage. Wind tears shingles, which falls under the wind deductible. A fallen limb then breaks a pipe and floods the kitchen, which is usually a standard-peril loss. Ask your agent in advance how your policy would split a mixed event. The answer changes what you pay out of pocket.

How a high deductible changes the "should I file?" decision

With a $1,000 flat deductible, nearly every real loss is worth a call. With a $14,000 deductible, the math flips. A $16,000 claim pays you $2,000 and goes on your claims history for years. A claim that barely clears the deductible can cost you more in future pricing than the check is worth.

So the rule changes. Before you file, get a contractor estimate, compare it to your deductible in dollars, and call your agent to ask how a claim of that size would affect renewal. You are not hiding anything. You are choosing whether a claim is worth opening. Also set aside cash equal to your deductible if you can. It is the number you actually carry.

Buying the percentage back down

A percentage deductible is often negotiable in ways a flat one is not. Some carriers file lower percentage options, or smaller premium credits, for homes with stronger roofs, impact-rated shingles, updated roof-to-wall connections, or storm shutters. The rules vary by state and by carrier, so ask directly: "What would it take to move from a 2% wind/hail deductible to 1%, or to a flat amount, and what would it cost?"

Two things make that conversation work. You need the dollar cost of each option, so you can compare the premium savings against the extra risk you carry. And you need proof of the features you already have: roof age, material, and any upgrades, with dates and photos. A roof replaced in 2022 that nobody documented is treated like an old roof.

Three questions to ask your agent before renewal

Send these in one email and keep the answers:

• What is my exact deductible in dollars for wind and hail, named storms, and winter storms, based on my current Coverage A limit?
• What would a lower percentage or a flat deductible cost me each year, and what home features would qualify me for it?
• If wind damage and water damage happen in the same storm, how many deductibles apply?

Those three answers turn a hidden line item into a number you can plan around.

Where Rafter fits

Rafter's AI-powered home risk assessment captures the facts that decide how a storm loss plays out: roof age and condition, material, flashing, drainage, and the protective features already on the house. It then builds a prioritized mitigation plan, so you know which upgrades reduce your exposure and which ones carriers recognize when they price your deductible.

It also keeps the documentation in one place: dated photos, service records, and upgrade invoices you can hand to your agent when you ask for a better deductible option.
