Picture this: it's late August, a storm is spinning in the Gulf, and you're on the porch in Slidell wondering what you'd actually owe if the roof peels back. Most St. Tammany homeowners know their regular deductible by heart. Far fewer know the number that matters most during hurricane season, and that gap tends to show up at the worst possible time.

This guide covers how Louisiana storm deductibles are calculated, what sets them off, and how state law limits how often you pay them.

Understanding Louisiana Hurricane and Named Storm Deductibles

A hurricane or named storm deductible is a separate deductible on your homeowners policy that applies only when a tropical system causes the damage. It is typically higher than the standard deductible used for fire, theft, or a burst pipe, and it is usually figured as a percentage of your home's insured value rather than a flat dollar amount.

Aubert Insurance Agency has worked with homeowners in Covington and Slidell since 1910, and this is still one of the most misunderstood parts of a policy. Most homeowners policies in Louisiana carry two deductibles side by side. One is the "all other perils" deductible, often a familiar figure like $1,000 or $2,500. The other sits quietly on the declarations page until a tropical system comes ashore.

The two work very differently. If a kitchen fire causes $8,000 in damage, you pay your flat deductible and the carrier handles the rest. If a tropical storm tears off shingles and lets water into the attic, the storm deductible may apply instead, and that number can be several times larger. Knowing which one applies to which kind of loss is the first step toward understanding your real exposure.

How Percentage Deductibles Change Your Out-of-Pocket Costs

Here's where the confusion usually starts. A percentage deductible is not a percentage of your claim. It's calculated from your dwelling coverage limit, called Coverage A, which is the amount your policy would pay to rebuild the house itself.

The Louisiana Department of Insurance notes that named storm deductibles typically run 2% to 5% of your insured value. So on a home insured for $350,000 with a 2% deductible, you'd cover the first $7,000 of storm damage yourself. That number holds whether the claim is $9,000 or $90,000.

A common mistake we see: a homeowner raises Coverage A after a renovation or because rebuild costs went up, which is a smart move. But nobody mentions that the storm deductible rose right along with it. Every time your dwelling limit changes, your hurricane deductible changes too.

Fixed Dollar vs. Percentage Deductibles

The differences are easy to see side by side:

• Fixed dollar deductible: A set amount, such as $1,000 or $2,500. It stays the same no matter how much your home is insured for. It typically applies to fire, theft, hail outside a named storm, and other covered perils.
• Percentage deductible: Tied to Coverage A. On a $400,000 home, 3% equals $12,000. It typically applies only to losses from a hurricane or named storm, depending on your policy wording.

Some carriers may offer a flat dollar hurricane deductible, while others may require a percentage. Louisiana's Regulation 93 requires insurers to give policyholders a specific hurricane deductible notice and disclose any premium savings from choosing a percentage-based option. Read that notice when it arrives. It's one of the few documents that spells out the trade-off in plain numbers.

What Triggers a Named Storm or Hurricane Deductible?

The trigger is defined by the National Hurricane Center, not by your carrier's judgment or by how bad the wind felt in your neighborhood. Under Louisiana law, a hurricane or named storm is a system declared as such by the National Hurricane Center. If the NHC hasn't named it, the storm deductible shouldn't come into play.

The wording in your specific policy controls the details. Many policies use language tied to NHC watches or warnings, meaning the deductible may apply to damage occurring from the time a hurricane or tropical storm watch or warning is issued for any part of Louisiana until a set period after it ends. Some policies define the window by landfall instead. These small differences can decide which deductible applies to a fallen oak that hit your roof the morning before landfall.

One thing to keep in mind: a storm doesn't need to reach hurricane strength. State regulators point out that a named storm deductible may still be triggered by a tropical storm, depending on how your policy is written. A "hurricane deductible" and a "named storm deductible" are not always the same thing, and the label on your declarations page matters.

The Louisiana Once-Per-Season Deductible Rule

Louisiana sits in a part of the Gulf where two storms in one season is not a far-fetched idea. Homeowners here remember years when back-to-back systems hit the same parishes within weeks. The state wrote a protection into law for exactly that situation.

Under La. R.S. 22:1337, hurricane or named storm deductibles on one- or two-family owner-occupied homes can only be applied once per calendar year. The statute requires that these separate deductibles work on an annual basis rather than per event. In practical terms, if you pay your full storm deductible after a July storm, a second storm in September does not reset the clock.

So what do you pay on the second claim? Once the annual hurricane deductible is fully satisfied, insurers typically apply your standard all-perils deductible, often $1,000 or $2,500, to later storm claims that year. If your first storm claim was smaller than your full hurricane deductible, the remaining balance may carry forward, so keep every claim document from earlier in the year.

The rule has limits. For commercial property and multi-peril policies, the once-per-season protection applies only when total insured value is under $20 million. Business owners and condo associations above that line should review their policies with that cutoff in mind.

Comparing Deductible Types and Costs

Percentages look small on paper. Dollars tell the real story. Here's what you'd owe out of pocket at common Louisiana deductible levels, using Coverage A amounts typical for homes around Covington and Slidell:

Compare those figures to a typical $1,000 or $2,500 all-perils deductible and the gap is obvious. A $400,000 home at 5% carries a storm deductible eight times larger than a $2,500 flat deductible.

Choosing a higher percentage usually lowers your premium, and that can be tempting. Louisiana premiums rose an average of 4.6% in 2025, a slower climb than 2023 but still real money. The question is whether your savings account could actually cover $20,000 the week after a storm. If it can't, the lower premium may cost you far more later.

Another way to lower the hurricane portion of your premium is a FORTIFIED roof. Regulation 136 requires insurers to offer premium credits for FORTIFIED-designated homes, specifically on the hurricane side of the rate.

Common Questions About Storm Coverage in Louisiana

Does my regular deductible apply to wind damage? Sometimes. Wind from a regular thunderstorm typically falls under your standard deductible, while wind from a named storm usually triggers the hurricane or named storm deductible.

What if a storm isn't named? If the National Hurricane Center never names the system, the storm deductible generally shouldn't apply. Your regular all-perils deductible would typically handle the claim instead.

Does my hurricane deductible cover flood damage? No. Standard homeowners policies typically exclude flood, so rising water needs a separate flood policy with its own deductible.

Can I switch from a percentage deductible to a flat dollar amount? Some carriers may allow it, often at a higher premium. Availability varies by company and by how close your home sits to the coast.

If two storms hit this year, do I pay two hurricane deductibles? Not on an owner-occupied one- or two-family home. Louisiana law limits the storm deductible to once per calendar year.

Where do I find my deductible? Look at your declarations page. It should list both deductibles, often with the hurricane amount shown as a percentage and a dollar figure.

Making the Right Choice for Your Property

Storm deductibles aren't complicated once you see the moving parts. They're separate from your everyday deductible, tied to your dwelling limit, triggered by an NHC-named system, and capped at once per calendar year for owner-occupied homes. The trouble is that most people only learn those details while standing in a wet living room.

Pull out your declarations page this week and do the math. Multiply your Coverage A by your storm percentage and ask yourself if that number fits your emergency fund. Check whether your policy says "hurricane" or "named storm," because a tropical storm could cost you more than you expect.

As an independent agency, Aubert Insurance Agency compares options from multiple carriers, so you can weigh different deductible levels against real premium numbers instead of guessing. We'd rather explain the fine print now than after landfall.
