What Is a Wind Mitigation Inspection, and How Does It Lower Your Florida Insurance?

Short answer: a wind mitigation inspection is a standardized assessment of your home's storm-resistant construction features — things like roof shape, how the roof is attached to the walls, and whether your windows and doors are impact-protected. Florida insurers use the results to calculate a windstorm discount on your homeowners policy, which makes it one of the more direct ways to lower your insurance bill on a Florida home.

What actually gets inspected

A licensed inspector completes a state-standardized form (historically OIR-B1-1802, with an updated version rolled out beginning April 1, 2026) documenting several categories of construction: roof covering, roof deck attachment, roof-to-wall connection, roof shape/geometry, opening protection, and secondary water resistance. Each is a real, physical feature of the home that affects how it performs in high wind.

The categories that matter most

• Opening protection — impact-rated windows, doors, garage doors, and skylights, or compliant hurricane shutters covering every opening. This is typically the single largest discount category; insurers generally require every opening to be protected to get full credit, so one unprotected window or an unrated garage door can limit the whole category's discount.
• Roof shape — hip roofs (sloped on all four sides) generally score better than gable roofs (with flat vertical ends) because they have less flat surface for wind to catch, and newer Florida construction increasingly uses hip or hip-combination designs for this reason.
• Roof-to-wall connection — how the roof structure is fastened to the walls (toe-nails versus engineered clips or straps) is a major factor in whether a roof stays attached during high wind, and a common failure point in older, pre-code homes.
• Roof deck attachment and secondary water resistance — how the roof decking is fastened and whether a secondary barrier exists to keep water out if the roof covering is compromised.

Why new construction tends to score well

Homes built to Florida's current building code have most of these features built in from day one — engineered roof-to-wall connections and modern roof decking are simply how the home was constructed, not an upgrade layered on afterward. Older homes can still score well, but it usually requires specific retrofits: adding hurricane straps, upgrading to impact windows, or replacing an aging roof with a wind-rated covering. This is part of why new construction often carries a lower windstorm premium than an equivalent older resale home.

What to do with the report

Once you have a current wind mitigation report, give it to your insurance agent — it directly feeds the windstorm portion of your quote. If you are buying a resale home, ask the seller whether a current inspection exists (they are typically valid five years) before assuming you need a new one, though getting your own after closing is common, especially if features have changed since the seller's report or the existing one is outdated. If you are buying new construction, ask your builder what documentation they provide at closing — many builders can supply this directly since the features are already part of the build.

The bottom line

A wind mitigation inspection turns your home's actual storm-resistant features into a documented insurance discount instead of an invisible advantage. It is one of the more concrete, controllable levers Florida homeowners have over their insurance bill, and it is worth understanding before you buy, not after your first renewal notice arrives.
