If you've been in Florida for any length of time, you've probably heard the term "wind mitigation inspection" — likely from an insurance agent who suggested you get one, or from a neighbor who mentioned it saved them money. But what it actually is, what it checks, and whether it's worth doing isn't always explained clearly.
Here's the plain-English version, written for homeowners in Stuart, Port St. Lucie, Jensen Beach, Palm City, Hobe Sound, and the rest of the Treasure Coast — where the insurance situation is real and where the potential savings are as high as anywhere in the state.
What Is a Wind Mitigation Inspection?
A wind mitigation inspection is an assessment of your home's structural ability to withstand hurricane-force winds. A licensed inspector walks through specific features of your roof and home, fills out a standardized Florida state form (OIR-B1-1802), and provides that report to your insurance carrier.
Your insurance company then applies discounts to the wind coverage portion of your premium based on what the report shows. The more features your home has that help it resist wind damage, the larger the discount. This isn't a judgment call — Florida law requires insurers to offer these discounts. The form exists specifically to make the process verifiable and standardized.
It's worth being clear on what this is not: it's not an inspection your insurer requires, it's not a pass/fail exam for your home, and it's not the same as a 4-point inspection (which evaluates your roof, HVAC, plumbing, and electrical for insurability). The wind mitigation inspection is entirely in your favor — it can only help your premium, never hurt it.
What Does the Inspection Actually Check?
The OIR-B1-1802 form covers seven specific categories. These are the things the inspector looks at and documents:
1. Building code and permit date. When your home was built or had its roof replaced matters significantly. Homes permitted after the 2001 Florida Building Code came into effect — which followed Hurricane Andrew's devastation — were built to higher wind standards from the start. If your roof was replaced after 2001 and properly permitted, that alone earns you credit.
2. Roof covering. The type of shingle or roofing material and whether it meets Florida Product Approval standards. This is one of the areas where a new roof has the most direct impact — a new installation can be verified against current approval standards in a way an older roof often can't.
3. Roof deck attachment. How the plywood or OSB sheathing is fastened to the rafters. Homes built or re-roofed with 8d nails at tighter spacing perform significantly better in high winds than older construction using staples or 6d nails at wider spacing. This is often one of the most valuable items on the report.
4. Roof-to-wall attachment. How the roof structure connects to the walls of your home. The presence of hurricane clips or straps — metal connectors that tie the roof directly to the wall framing — is one of the biggest single factors in wind resistance. Homes without them are substantially more vulnerable to roof loss in a storm.
5. Roof geometry. The shape of your roof. A hip roof (slopes on all four sides) performs better aerodynamically than a gable roof (triangular ends) in high winds. If your home has a hip roof, that's a credit. If it's a flat or gable design, it's a neutral or negative.
6. Secondary water resistance (SWR). A layer of protection beneath the shingles — typically a self-adhering rubberized membrane — that prevents water intrusion if the shingles are lost in a storm. This is increasingly standard in new roof installations and is specifically required for certain zones in South Florida.
7. Opening protection. Whether your windows and doors have hurricane-rated protection — impact glass, accordion shutters, or rated panels. This one is independent of the roof, but it's on the same form.
How Much Can It Actually Save You?
The range most commonly cited is 10% to 45% off the wind coverage portion of your premium — and in Florida, wind coverage is typically a large part of what you pay. For many Treasure Coast homeowners, the wind portion represents 40% or more of the total premium.
In practical terms: if you're paying $4,000 a year for homeowner's insurance and the wind portion is $2,000 of that, a 30% wind mitigation discount could save you $600 per year. The inspection itself typically costs between $75 and $200. The math on getting the inspection done is almost always favorable.
The actual savings depend heavily on what your home has. A newer home with a hip roof, hurricane clips, SWR, and properly fastened deck sheathing could see the top end of that range. An older home with a gable roof, no clips, and older deck fastening will see less — but may still see meaningful savings, and the inspection itself identifies exactly what upgrades would increase the discount.
What a New Roof Does to Your Wind Mitigation Report
This is the part we see most homeowners not fully understand. A wind mitigation inspection documents what exists on your home right now. If your roof is 18 years old with older deck fastening and no secondary water resistance layer, that's what the report shows — and the discounts are limited accordingly.
When we replace a roof, every element we install is done to current Florida Product Approval standards: 8d ring-shank nails at the required spacing, self-adhering SWR membrane on the full deck, and properly installed drip edge and flashing throughout. All of it is permitted and documented. When the inspector comes out after replacement, those items are verifiable — and the report reflects them.
This is why a new roof isn't just about protection from weather. It's a documented upgrade to your home's wind resistance profile, with a paper trail that your insurer can verify. The combination of a new permitted roof and a wind mitigation inspection is where homeowners on the Treasure Coast see the most meaningful insurance impact.
The My Safe Florida Home Program
If the cost of a new roof or wind-resistant upgrades is a barrier, it's worth knowing that Florida's My Safe Florida Home program offers grants specifically for hurricane-hardening improvements. The program provides a matching grant of $2 for every $1 you spend on qualifying upgrades, covering up to two-thirds of eligible project costs. Low-income households may qualify for grants with no match required.
Funding availability changes — the program has had periods where demand exceeded available grants — so it's worth checking current availability directly with the Florida Department of Financial Services if this applies to your situation. We can tell you whether the work you're considering qualifies.
Who Can Do a Wind Mitigation Inspection in Florida?
Florida law specifies who is authorized to complete the OIR-B1-1802 form. Qualified inspectors include licensed home inspectors, general contractors, building contractors, architects, engineers, and building inspectors. A roofing contractor alone is not automatically qualified to certify the form — the inspector needs to hold one of those specific license types.
The inspection typically takes one to two hours. You'll receive a written report with photos documenting each category. That report goes directly to your insurance carrier — you can share it at renewal or mid-term, and insurers are required to apply the applicable discounts.
The report is valid for five years unless there are material changes to the roof or structure.
Is It Worth Getting One?
Almost always yes, if your home is older than a few years and you haven't had one done recently.
The cost of the inspection is low. The potential savings are real and ongoing — it's not a one-time benefit, it applies to every renewal for as long as the report is valid. And at minimum, it tells you exactly what features your home has and what upgrades would improve your discount at the next renewal or roof replacement.
If your roof is nearing the end of its useful life and you're planning a replacement, the right sequence is: replace the roof, then schedule the wind mitigation inspection. The report will reflect the full upgrade.
If you're not planning a replacement but haven't had an inspection, schedule one first and see what's there. You may already have more credits than your current premium reflects.
