A plain-English guide to what wind mitigation inspectors look for on your roof, why it matters to your premium, and how a modern re-roof can strengthen the report.
If you own a home in Manatee or Sarasota County, your windstorm coverage is often one of the largest pieces of your insurance bill. The good news: Florida law lets you document the wind-resistant features of your home and earn credits for them. The tool that does this is the wind mitigation inspection, and your roof is the star of the show.
Here is a clear, no-hype walkthrough of what the inspection checks, why it matters to your premium, and how a properly permitted re-roof can strengthen your report. This is general information to help you understand the process — it is not insurance or legal advice, and every carrier and policy is different. Always confirm specifics with your agent or insurer.
A wind mitigation inspection is a short, non-invasive evaluation that records how well your home is built to resist hurricane-force wind. The findings are recorded on a single statewide form — the Uniform Mitigation Verification Inspection Form (OIR-B1-1802) — that every Florida property insurer is required to accept. Once completed and accurate, the form is generally valid for up to five years, as long as the information stays accurate and no major changes are made to the structure.
The inspection is performed by a qualified inspector, and in Florida that list includes certain licensed contractors. The report does not change your insurance on its own — you (or your agent) submit it to your carrier, and the insurer applies any credits you qualify for.
Most of the available credits are tied to the roof. Here is what the inspector is looking for, and why each item matters in a windstorm.
The inspector documents the type of covering (asphalt shingle, tile, metal, and so on), when it was installed, and whether it meets Florida Product Approval or Miami-Dade standards. A covering installed under a permit dated to a modern code cycle generally scores better than an older, undocumented roof. This is why the permit date and product approval number on a recent re-roof matter so much.
This is how the plywood or sheathing is fastened to the trusses below. Older homes were often built with shorter nails or staples spaced far apart. Modern code calls for stronger fasteners — for example, 8d ring-shank nails at roughly 6-inch spacing — which dramatically improve the deck's resistance to uplift. Better deck attachment is one of the most meaningful items on the form.
This checks how your roof structure is anchored to the walls — the hardware that literally holds the roof down in high wind. Inspectors classify these connections from weakest to strongest:
Insurers generally want to see the connector secured with the required number of nails on every truss before granting the credit, and the inspection is scored on the weakest connection found. Stronger connections usually mean a larger discount.
Geometry matters. A hip roof — which slopes down on all four sides — tends to shed wind better than a gable roof with its flat vertical end walls. Because of that performance, hip roofs often qualify for a roof-shape credit. You cannot easily change your roof's shape, but it is worth knowing how yours is classified.
Also called a "sealed roof deck," SWR is an extra barrier — commonly a self-adhering, peel-and-stick membrane over the deck seams or the entire deck — that helps keep water out if the top covering is torn off by a storm. It protects the inside of your home, and it is a documented credit item on the form.
The windstorm portion of your premium is where these credits apply — and on many Florida policies that portion is a large share of the total bill. Florida homeowners frequently see meaningful reductions on that portion after submitting a complete report — published figures commonly fall in roughly the 10% to 45% range, with the exact number depending on your carrier, your home's features, and your location. A home that lands strong marks across deck attachment, roof-to-wall connections, roof shape, and SWR will generally earn more than one that does not.
Two honest caveats. First, savings vary widely — there is no guaranteed dollar amount, and the only way to know yours is to have the inspection done and submit it. Second, a wind mitigation inspection is not the same as a four-point inspection or a roof condition report; carriers may ask for those separately.
If your roof is older, near the end of its service life, or was installed before modern wind standards, a re-roof can do double duty: it protects your home and it can add features your current roof simply does not have. When a roof is replaced today under permit, it is built to the current Florida Building Code, which has tightened steadily over the years. A code-compliant re-roof can introduce or upgrade several of the exact items the inspection rewards:
Roof-to-wall connections are structural and are not always upgraded by a standard re-roof, but a contractor can tell you whether a retrofit is possible and whether it makes sense for your home. The key point: when you replace a roof, ask your contractor to make sure the work is positioned to maximize your wind mitigation results and to give you the permit documentation your inspector and insurer will want.

It varies by carrier, home, and location, but published figures commonly fall in the 10% to 45% range on the windstorm portion of your premium. There is no guaranteed amount — the only way to know your savings is to have the inspection completed and submit the form (OIR-B1-1802) to your insurer. This is general information, not insurance advice.
The statewide form is generally valid for up to five years, provided the information stays accurate and no major changes are made to the structure. If you re-roof or make structural changes, a new inspection can capture the improved features. Confirm the current validity period with your agent.
Often, yes. Hip roofs slope down on all four sides and tend to handle high wind better than gable roofs, which have flat vertical end walls. Because of that performance, hip roofs frequently qualify for a roof-shape credit. Your inspector classifies the actual geometry of your roof on the form.
It can. A re-roof permitted to current Florida Building Code may add features the report rewards — a documented covering with a current product approval, improved deck fastening, and a sealed roof deck (secondary water resistance). Roof-to-wall connections are structural and aren't always upgraded by a standard re-roof, so ask your contractor what's possible for your home.
No pressure, no sales games — just an honest look at your roof from a dual-licensed contractor.
