Wind Mitigation Inspections: How Tampa Homeowners Save 10–45% on Insurance
A wind mitigation report can dramatically reduce your homeowner's insurance premium in Florida. Here's exactly how it works and who qualifies.
What Is a Wind Mitigation Report?
A wind mitigation report (formally the OIR-B1-1802 form) is an official document completed by a licensed inspector that describes the wind-resistant features of your home's roof and openings. Florida law requires all licensed insurers to offer credits based on this report. You pay for the inspection, you receive the form, and you submit it to your insurer — who then recalculates your premium with the applicable discounts applied. The savings are permanent for the life of the report (5 years).
What Inspectors Evaluate
The inspection covers six main areas. Roof shape: hip roofs earn the largest credit because they present less wind exposure on each face. Roof deck attachment: how the plywood is fastened to the trusses affects uplift resistance — 8d nails at 6-inch spacing earn better credits than 6d nails at 12 inches. Roof-to-wall connections: clips and straps that tie the roof to the walls provide critical resistance to the roof lifting off. Roof covering type: FBC-compliant shingles and tiles earn credits. Opening protection: impact-rated windows, doors, and garage doors significantly reduce risk. Secondary water resistance: a self-adhering peel-and-stick underlayment protects the interior if shingles are lost.
Typical Savings Ranges by Feature
Savings vary significantly based on what features your home has. A hip roof alone can save 15–30% over a gable roof. Adding secondary water resistance (peel-and-stick underlayment) typically saves another 5–10%. Full opening protection — impact windows and doors throughout — can reduce your wind premium by 40–45% on its own. Most Tampa homes have some of these features, which is why even older homes often see meaningful savings. The inspection cost of $75–$150 typically pays for itself within the first month of savings.
Citizens Insurance Requirements
If you have Citizens Property Insurance — Florida's insurer of last resort — a wind mitigation inspection isn't just beneficial, it may be required for new policies or renewals. Citizens uses the inspection results to verify your home's features and price your policy accordingly. Homes with better wind resistance features pay lower Citizens premiums. If you're shopping for Citizens coverage or have a policy up for renewal, get an inspection before submitting your application.
How a New Roof Improves Your Score
An older roof installed before the 2007 Florida Building Code updates may lack key features that modern roofs include as standard — secondary water resistance, compliant fastening patterns, and rated shingles. A new roof installation by a licensed contractor includes documentation of all these features, often allowing your inspector to check every box on the form. Homeowners who install a new GAF roof frequently see their wind mitigation score jump significantly, producing insurance savings that offset thousands of dollars of the roof's cost over the 5-year report period.
How Often to Get an Inspection
Reports are valid for 5 years. After 5 years, you need a fresh inspection to maintain your discounts. If you have a new roof installed, get a new inspection immediately after — don't wait for the old one to expire. If you add impact windows or upgrade your opening protection, schedule a new inspection right away to capture those additional credits. Changes to your roof structure between inspections should also trigger a new report.
