Wind Mitigation Inspection in Florida: How to Save Up to 45% on Insurance

Florida homeowners pay some of the highest windstorm insurance premiums in the country. But there is a straightforward way to cut that cost significantly: a wind mitigation inspection. This one report, which takes about 30 minutes and costs $75 to $150, can reduce your windstorm premium by 15% to 45%. If you have never had one done, or if you recently replaced your roof, you are almost certainly leaving money on the table.

What Is a Wind Mitigation Inspection?

A wind mitigation inspection is a standardized evaluation of your home's ability to withstand hurricane-force winds. A licensed inspector examines specific construction features of your roof and structure, then fills out the state-mandated OIR-B1-1802 form. Your insurance company uses that form to calculate premium discounts based on which wind-resistant features your home has.

Florida law (Section 627.0629, Florida Statutes) requires insurers to offer discounts for homes with verified wind-resistant construction. The inspection proves what your home actually has. Without it, your insurer assumes the worst and charges you the full rate. That is why this single piece of paperwork is the most cost-effective step most homeowners can take to lower their insurance bill.

The 7 Items on the OIR-B1-1802 Form

The Florida wind mitigation form evaluates seven specific construction features. Each one affects your discount independently, so even partial upgrades can save you money.

• Building Code Year. When was the original building permit issued? Homes built after the 2002 Florida Building Code took effect on March 1, 2002 automatically qualify for a baseline discount because the code mandated stronger construction. Homes built after 2007 may qualify for even better rates.
• Roof Covering. What type of roofing material is installed, and does it meet the Florida Building Code in effect at the time of installation? A roof covering installed under the current FBC with proper permit and inspection earns a discount. Older coverings without documentation typically do not.
• Roof Deck Attachment. How is the plywood or OSB sheathing attached to the trusses or rafters? The form identifies several methods ranging from 6d nails (weakest) to 8d ring-shank nails or screws at close spacing (strongest). Better attachment means bigger discounts.
• Roof-to-Wall Connection. How is the roof structure connected to the exterior walls? This is one of the highest-value items on the form. Toe nails (the weakest) provide no discount. Clips provide a moderate discount. Hurricane straps that wrap over the truss and are nailed on both sides earn the largest discount in this category.
• Roof Geometry. Is your roof a hip roof, a gable roof, or a combination? A hip roof, where all sides slope downward to the walls, performs best in high winds because there are no flat vertical surfaces for wind to push against. A 100% hip roof earns the full geometry discount. Flat and gable roofs earn less or nothing.
• Secondary Water Resistance (SWR). Does your roof deck have a sealed barrier underneath the shingles or tiles? SWR means the deck itself is sealed with self-adhering modified bitumen tape or a full peel-and-stick underlayment, so even if the roof covering blows off, water cannot penetrate the decking. This feature earns a significant discount.
• Opening Protection. Are all exterior openings, including windows, doors, skylights, and garage doors, protected against windborne debris? This means impact-rated windows and doors, or approved hurricane shutters on every opening. All openings must be protected to earn the full discount. Missing even one can disqualify you.

How Much Can You Actually Save?

The exact discount depends on your specific home features, your insurance carrier, and your location in Florida. But here are realistic ranges we see on policies for homes in Polk County and Central Florida:

• Minimal features (post-2002 code, basic roof covering compliance): 10% to 15% off windstorm premium.
• Moderate features (hurricane clips, FBC-compliant roof, partial opening protection): 20% to 30% off windstorm premium.
• Strong features (hurricane straps, hip roof, SWR, full opening protection): 35% to 45% off windstorm premium.

On a typical Polk County home with a $2,500 annual windstorm premium, that translates to savings between $250 and $1,125 per year. The inspection pays for itself in the first month or two of reduced premiums.

Which Features Get the Biggest Discounts?

Not all seven items on the form carry equal weight. If you are looking to maximize your savings, these four features have the largest individual impact on your premium:

• Hip roof geometry. A 100% hip roof is one of the easiest wins if your home already has one. There is nothing to install or upgrade. It just needs to be documented on the form.
• Hurricane straps or clips. Upgrading from toe nails to hurricane straps is one of the most cost-effective improvements a homeowner can make. Straps wrap over the top of each truss and are nailed into the wall framing on both sides, creating a continuous load path from the roof to the foundation.
• Sealed roof deck (SWR). When we do a roof replacement, applying SWR is a relatively small additional cost that earns a substantial insurance discount for the life of the roof.
• Impact-rated opening protection. Impact windows, impact doors, and wind-rated garage doors on every exterior opening earn the full opening protection discount. This is typically the most expensive upgrade, but it also provides the largest single discount on the form.

What Does a Wind Mitigation Inspection Cost?

In Central Florida, a wind mitigation inspection typically costs between $75 and $150. Some inspectors charge on the higher end if they combine it with a four-point inspection, which many insurers also require for older homes. Either way, the cost is minimal compared to the annual savings. Even a conservative 15% discount on a $2,000 windstorm premium saves you $300 per year, meaning the inspection pays for itself within the first premium cycle.

The report is valid for five years, so once you have it, you do not need another one unless you make changes to your roof or structure that would affect the ratings. After a roof replacement or significant upgrades, you should get a new inspection to capture the improved ratings.

When Should You Get a Wind Mitigation Inspection?

There are three situations where getting a wind mitigation inspection makes clear financial sense:

• After a roof replacement. A new roof installed under the current Florida Building Code will almost always qualify for better discounts than your old roof. Modern code requires stronger deck attachment, better underlayment, and improved fastening. If your roofer applied SWR or you upgraded your roof-to-wall connections during the project, the savings increase further. We recommend scheduling a wind mitigation inspection within 30 days of your roof replacement being completed.
• After structural upgrades. If you installed impact windows, added hurricane shutters to every opening, or reinforced your roof-to-wall connections with clips or straps, a new inspection will document those improvements and unlock additional discounts.
• If you have never had one. Many homeowners in Polk County have homes that qualify for meaningful discounts but have never submitted the form to their insurer. If your home was built after 2002, or if you replaced your roof in the last 20 years, there is a strong chance you are overpaying. A roof inspection can help determine where you stand.

Why a New Roof Almost Always Qualifies for Better Discounts

This is something we explain to homeowners regularly. The Florida Building Code has gotten significantly stricter since 2002, and each update raises the bar on wind resistance. When you get a new roof today, the code requires 8d nails at 6-inch spacing on the edges of the roof deck, rated underlayment, proper flashing, and fastening patterns designed to resist uplift. These requirements did not exist 20 or 30 years ago.

That means a roof installed in 2026 under the current FBC will score better on the wind mitigation form than a roof installed in 1998, even if the older roof is still in decent shape. The construction methods are simply stronger now. If you are already planning a roof replacement, it is worth discussing SWR and upgraded roof-to-wall connections with your contractor before the project starts. Those additions are far cheaper to include during a reroof than to retrofit later.

If you are navigating an insurance claim for roof damage, the replacement roof will almost certainly improve your wind mitigation ratings and lower your premiums going forward.

How American Roofing FL Handles Wind Mitigation

We perform wind mitigation inspections for homeowners across Polk County, and we also handle the roofing work that can improve your ratings. When we do a roof replacement, we walk through the wind mitigation form with you before the project starts so you understand which features will earn discounts and which upgrades are worth the investment.

For example, adding secondary water resistance during a reroof typically adds a modest amount to the project cost but can save hundreds per year on insurance. Upgrading from toe nails to hurricane straps during a reroof is another high-value addition that pays dividends for years.

We also recommend that homeowners prepare for storm season proactively. Our hurricane roof preparation checklist covers the practical steps you can take before a storm hits, and many of those steps overlap with features that improve your wind mitigation rating.
