What is a wind mitigation inspection?
A wind mitigation inspection documents the storm-resistant features of your home — things like the roof covering, how the roof attaches to the walls, the roof shape, and whether your windows and doors are protected — so your insurer can apply premium discounts. In Florida, those discounts aren't optional for insurers: state law requires every residential property insurer to offer credits for qualifying wind-mitigation features. For most Central Florida homeowners, this inexpensive inspection is one of the few ways to actively lower a homeowners premium.
Key takeaways
- A wind mitigation inspection documents wind-resistant features to earn insurance discounts.
- Florida law (Statute 627.0629) requires insurers to offer these mitigation credits.
- Discounts apply to the windstorm portion of your premium — often a large share in Florida.
- The uniform form (OIR-B1-1802) is valid up to five years.
- It typically costs $75–$150 and often pays for itself in the first year.

What it documents
The inspection records specific construction features that make a home more likely to survive a hurricane intact. Each one can translate into a discount:
| Feature | Why it earns a credit |
|---|---|
| Roof covering | Whether it meets current Florida Building Code |
| Roof deck attachment | Nail size and spacing holding the deck down |
| Roof-to-wall connection | Clips, single wraps, or double wraps vs. toe-nails |
| Roof shape | Hip roofs shed wind better than gable roofs |
| Secondary water resistance | A barrier that keeps water out if shingles fail |
| Opening protection | Impact-rated windows, doors, and shutters |
The strongest combinations — a hip roof, double-wrap straps, a code-compliant covering, a secondary water barrier, and full opening protection — earn the deepest discounts. Even an older home often qualifies for more than the owner expects, especially if it's had a re-roof done to current code.
The discounts and the law
Here's why this inspection is worth your time. Under Section 627.0629, Florida Statutes, every residential property insurer in the state must offer premium discounts, credits, or rate differentials for documented wind-mitigation features. This isn't a courtesy — it's a legal requirement, and the credits are documented on a standardized state form.
The discounts apply to the windstorm portion of your premium, which in Florida is frequently a large share of the total bill. The savings depend on your home and insurer, but homes with strong features can see meaningful reductions. The state's Office of Insurance Regulation wind mitigation resources explain the program, and the Florida Division of Emergency Management publishes guidance on the mitigation features themselves. As of the 2026 revision, the uniform form was updated with new discount tables and stricter documentation for impact windows, roof coverings, and roof-to-wall connections.
What it costs and how long it lasts
A wind mitigation inspection typically costs about $75–$150, paid by the homeowner. Because the discounts recur every year you hold the policy, the inspection often pays for itself in the first year or two — and then keeps saving you money after that.
The resulting uniform mitigation verification form (OIR-B1-1802) is valid for up to five years, as long as you make no material changes to the structure and the form contains no inaccuracies. After five years, or sooner if you make a qualifying upgrade like new impact windows, you renew it with a fresh inspection. Keep a copy — when you shop policies, handing a current form to a new carrier lets them price in your discounts immediately.
Wind mitigation vs. 4-point
These two inspections are easy to mix up, but they do different jobs. A 4-point inspection assesses the condition of your roof, electrical, plumbing, and HVAC to decide whether the home is insurable — it's about getting coverage, usually on older homes. A wind mitigation inspection documents wind-resistant features to lower the premium — it's about paying less.
You're not choosing between them. Many Florida homeowners get the 4-point because a carrier requires it, and the wind mitigation report because it saves money — often in the same visit. If you're already paying for an inspector on an older home, ask about doing both.
How to improve your wind mitigation score
If your inspection comes back light on credits, several upgrades can earn more — and many double as real storm protection. Opening protection is often the highest-value move: impact-rated windows or hurricane shutters on every opening can unlock a significant credit, and our guide to shutters vs. impact windows compares the options. A re-roof to current code can upgrade your roof covering, deck attachment, and secondary water resistance all at once.
The catch is sequencing: do the upgrade, then re-inspect to capture the new credits on a fresh form. Spending on impact windows and never updating your mitigation form means leaving the discount on the table. If a re-roof is already on your horizon because of your roof's Florida lifespan, plan the wind mitigation re-inspection to follow it.
Who can perform one
The inspection must be completed by an authorized inspector — typically a licensed home inspector, a general or roofing contractor, a building-code inspector, an architect, or an engineer. Insurers will not accept a homeowner's self-assessment; the value of the form is that an authorized professional has verified each feature.
When booking, confirm the inspector regularly performs wind mitigation inspections and provides the current OIR-B1-1802 form. A thorough inspector who knows the form well will document every feature you qualify for, rather than rushing and missing a credit you're entitled to.
Where to start
Start by checking whether you've ever had a wind mitigation inspection, and whether the form is still within its five-year window. If not, getting one is among the cheapest ways to cut a Florida premium. To strengthen your score, our hurricane shutters directory and Tampa city page list local companies for opening protection, with more across the full directory. Get the inspection from an authorized inspector, hand the form to your insurer, and re-inspect after any qualifying upgrade.
