Wind Mitigation Inspections: The Florida-Mandated Insurance Discount Most Homeowners Are Missing (2026)
The Short Version
A wind mitigation inspection is a Florida-standardized evaluation that documents your home's hurricane-resistant features — and Florida Statute 627.0629(1) requires every property insurer in the state to discount the windstorm portion of your premium based on what it finds. For nearly every Jacksonville home, the roof drives the score. A hip roof shape, hurricane clips or straps connecting roof to wall, ring-shank nails on the roof deck, a peel-and-stick secondary water barrier, and a roof installed under the 2001 Florida Building Code or later are the credits that meaningfully move the needle. The inspection runs $100–$150 locally, takes under an hour, lasts five years, and uses the OIR-B1-1802 form (significantly updated by the Florida Office of Insurance Regulation effective April 1, 2026). According to data from the state's My Safe Florida Home program, homeowners who complete qualifying improvements report average insurance savings of over $900 per year. The catch: if your roof can't earn the credits, the inspection can't either — which is why what's built into a new NEXGEN install matters before the inspector ever shows up.

There's a state-mandated insurance discount sitting on most Jacksonville roofs, completely untouched. Some homeowners are five years overdue claiming it. Plenty have never claimed it at all. Florida calls it the wind mitigation inspection — and if you haven't pulled a fresh report in the last five years, you're almost certainly overpaying your carrier.
This is the guide every Jacksonville homeowner should read once: what the inspection actually checks, which credits realistically apply to a Northeast Florida home, what it's worth in dollars, and what a roofer (not an inspector, not an agent) wishes more homeowners knew before they bought their next roof.
Why Florida Invented This Inspection in the First Place
After Hurricane Andrew flattened South Florida in 1992, the Legislature spent the next decade rewriting how Florida builds. That work culminated in the 2001 Florida Building Code (effective March 1, 2002) and Florida Statute 627.711 — the law that requires every property insurer operating in the state to offer discounts when a homeowner can document hurricane-resistant construction features.
The wind mitigation inspection is how you prove what your home has. The inspector doesn't grade you. They don't pass or fail you. They check boxes on a form. Your carrier converts those boxes into credits, and your premium drops accordingly. It's one of the few consumer protections in Florida insurance law that puts a direct dollar amount in the homeowner's pocket — and it's under-claimed at a staggering rate.
The OIR-B1-1802 Form (And Why the 2026 Version Matters)
The form is standardized statewide: OIR-B1-1802, officially titled the Uniform Mitigation Verification Inspection Form. Every wind mitigation report uses it. The Florida Office of Insurance Regulation updated the form effective April 2026, and that's the version your inspector should be filling out today. Insurers are required by law to accept it.
If a contractor or inspector hands you a different document — a "proprietary inspection," a "mitigation summary," a generic PDF — it's not the form your carrier will credit. Always ask: "Is this the current OIR-B1-1802?" If the answer isn't an immediate yes, find another inspector.
The Seven Boxes That Determine Your Discount
Each section of the OIR-B1-1802 corresponds to a separate discount on the windstorm portion of your premium. Some are worth a lot. Some barely move the needle. Here's what your inspector is actually documenting, in the order they appear on the form.
Building Code (When Your Home Was Permitted)
1 Building Code (When Your Home Was Permitted)
The first checkbox isn't about your roof — it's about your permit date. Homes built under the 2001 Florida Building Code (permitted March 1, 2002 or later) are automatically credited with stronger construction. Some carriers apply a flat discount just for this. If your home predates March 2002 but you've since installed a new roof under modern code, the new roof can still earn separate credits even when the home itself doesn't qualify here.
2 Roof Covering
This is where most Jacksonville homes win or lose. The inspector confirms whether your roof covering meets current Florida Building Code wind standards (FBC) or the older Miami-Dade HVHZ standard. To qualify, your shingles must be rated for the wind speeds required by code in your zone, the install needs a valid permit on file, and the inspector typically wants documentation of the product approval (an NOA — Notice of Acceptance, or an FL product approval number).
A shingle that says "wind-rated" on the wrapper but was installed without a permit doesn't always count. This is why so many homeowners with seemingly new roofs are still paying inflated premiums — the install didn't close out cleanly, the documentation never reached the inspector, and the credit never landed.
3 Roof Deck Attachment
The inspector heads to your attic and counts the nails. They're looking at the spacing and type of fasteners holding your roof deck (sheathing) to the trusses. Ring-shank nails at tight spacing earn substantially more credit than smooth-shank nails at standard spacing — and on roofs installed before the 2001 code, the difference can be meaningful. This is one of the credits a new NEXGEN install captures by default because ring-shank fasteners are our standard, not an upgrade.
4 Roof-to-Wall Connection
This is the single biggest credit on most Jacksonville reports. The inspector documents how your roof structure is attached to your home's exterior walls. The hierarchy, weakest to strongest: toe nails, then clips, then single wraps, then double wraps. Hurricane straps and clips earn dramatically more credit than the toe-nailed construction common on older Jacksonville homes — anything built pre-1980 in particular. Retrofitting clips through the soffit or during a re-roof is one of the highest-ROI improvements the My Safe Florida Home program will fund.
5 Roof Geometry (The Hip-vs-Gable Credit)
Hip roofs — the kind that slope on all four sides like a pyramid — perform better in high winds than gable roofs because they have no flat vertical wall for wind to catch. Florida carriers apply a meaningful discount for hip roofs (or roofs that are at least 90% hip by perimeter). If your home has a complex roof with mixed geometry, the inspector measures the percentage. Most single-story ranch homes across Mandarin, Arlington, and Jacksonville's Westside are hips. Most two-story homes in newer subdivisions are gables. You can't change this credit without rebuilding the structure — but you can confirm it's being claimed correctly.
6 Secondary Water Resistance (SWR)
Also called a "sealed roof deck" or peel-and-stick underlayment. SWR is a fully adhered membrane installed directly to your roof deck before the shingles go on — so if wind tears your covering off, the membrane keeps water out of your home. It earns its own line-item credit. Standard felt underlayment does not qualify. Modern self-adhered synthetic underlayments do. Most NEXGEN installs include SWR-qualifying underlayment as standard, but the credit only applies if it's documented on the permit and visible to the inspector.
7 Opening Protection
This one isn't a roofing credit, but it caps your potential discount. Opening protection means windows, doors, and skylights with impact-rated glass, hurricane shutters, or storm panels. To qualify, 100% of openings on the home must be protected. Most Jacksonville homes outside the beaches don't have impact windows, which limits the maximum possible discount. The encouraging news: even with no opening protection at all, the roofing credits alone are typically worth pursuing.
The Seven Credits on Your OIR-B1-1802
Which Credits Actually Move the Needle in Jacksonville
Not every credit is created equal, and Jacksonville isn't Miami. A few patterns hold across nearly every wind mit report we see in Duval, Clay, St. Johns, and Nassau counties.
Roof-to-wall connection is almost always the heaviest credit on the report. The jump from toe-nailed construction (common in pre-1990s Jacksonville homes) to clips or straps is the single largest dollar swing on most reports. A retrofit during a re-roof is the most cost-effective time to capture it.
Roof covering compliance and secondary water resistance are the two credits most often missed on otherwise-recent roofs. They get missed because the install paperwork is incomplete, the underlayment wasn't documented, or the inspector couldn't physically verify what was installed. This is a documentation problem, not a roof problem.
Roof geometry is what it is — your home is either hip or gable. If you have a hip and your last report didn't claim it, your insurer left money on the table. Pull the old report and look.
Opening protection is the credit most Jacksonville homeowners can't fully capture without a meaningful investment, since impact windows on a full home easily run five figures. This is where the My Safe Florida Home grant program becomes interesting — the state will match up to $10,000 toward opening protection upgrades for qualifying homeowners. Worth knowing about, even if it's not strictly a roofing topic.
Building code (permit date) is binary — either your home was permitted under the 2001 FBC or it wasn't. If it was, make sure your inspector and carrier both have the documentation.
Jacksonville Credit Priority
Where the dollar swings actually happen on Northeast Florida wind mit reports
What This Is Actually Worth in Dollars
Florida Statute 627.0629(1) requires every property insurer in the state to offer discounts when a homeowner documents qualifying mitigation features on the OIR-B1-1802 form. The discounts apply to the windstorm portion of your premium — which in Florida typically represents 30%–70% of your total annual bill, depending on your home's value and zone.
According to the Florida Division of Emergency Management's Wind Mitigation Booklet, the maximum total discount available to a homeowner under the program is 88% of the windstorm portion of premium. Important caveat: credits are not cumulative. The state publication is explicit about this — when one credit applies, others are reduced. Only homes with full opening protection plus comprehensive roof credits approach the 88% ceiling. Most Jacksonville homes outside the beaches lack impact windows and won't get close to that maximum, but the roofing credits alone are typically worth pursuing.
Real-world averages tell the more useful story. Data collected by the state's My Safe Florida Home program shows homeowners who complete qualifying improvements report average annual insurance savings of over $900. The Florida Office of Insurance Regulation's 2024 Residential Wind-Loss Mitigation Study found that homes with comprehensive wind protection can see 20%–30% off their total annual premium. The inspection itself runs $100 to $150 in the Jacksonville market when paid out of pocket, and the credits apply for five full years before re-inspection is required.
If you've never claimed your credits, or your last report is more than five years old, you are almost certainly overpaying. The inspection only documents qualifying features — homes without them simply don't receive credits, but the inspection itself isn't used to add charges to your policy.
What the Math Looks Like
Illustrative scenario for a Jacksonville home with a code-compliant roof, hip geometry, hurricane clips, and secondary water resistance — but no opening protection. Actual savings vary by carrier, home value, zone, and which credits the OIR-B1-1802 documents. State My Safe Florida Home program data reports average savings of over $900 per year across participants. The inspection only documents qualifying mitigation features; homes without them simply don't receive credits.
Five Times the Inspection Pays for Itself Immediately
If any of these describe your home today, schedule the inspection this month.
Your home was built after March 2002 and you've never had a wind mit inspection on file with your current carrier.
You've had a roof replacement in the last five years. The new roof almost certainly qualifies for credits your old report can't claim.
You've added hurricane shutters, impact windows, or any opening protection. Even partial protection can shift the score if 100% coverage is achieved.
Your last inspection is more than five years old. The report has expired and your carrier is no longer required to apply the credits.
You just received a non-renewal letter citing your roof. Every credit on your report is now leverage with a new carrier — see our guide on what to do your homeowners insurance is canceled because of your roof.
What Competitors Don't Tell You About a New Roof
The components installed during a roof replacement determine which credits the inspector can check months or years later. This is the part most contractors don't walk you through, because most contractors aren't thinking about your insurance discount — they're thinking about finishing the job and moving to the next driveway.
Every NEXGEN install includes the components that earn the roofing-side credits on the OIR-B1-1802 by default. Ring-shank nails on the deck. Self-adhered synthetic underlayment that qualifies as Secondary Water Resistance. Code-compliant shingle systems with valid product approvals and a closed-out permit. Documentation that reaches the inspector and the carrier when it's time to file. Our residential roofing process is built around this — the permit closes, the photos are on file, the SWR is documented, and the credits are claimable from day one.
If you're replacing a roof in 2026, ask any contractor you're considering three questions before signing. Is ring-shank fastening standard on your installs, or an upgrade? Does your standard underlayment qualify as Secondary Water Resistance on the OIR-B1-1802? Will the permit be formally closed out, with photo documentation available for my wind mit inspection?
If those answers aren't immediate, you're paying for a roof that won't fully earn its insurance discount. For more on what separates a real install from a rushed one, see our breakdown of why most roofs fail before the job even start.
Common Mistakes That Cost Jacksonville Homeowners Credits
A handful of mistakes show up over and over on Jacksonville wind mit reports — each one quietly costing homeowners money.
Hiring an inspector unfamiliar with the OIR-B1-1802. The form is detailed and the photo documentation requirements are specific. An inspector who rushes it leaves credits unclaimed.
Getting the inspection before your new roof's permit closes. The carrier can't apply credits for an install that isn't officially completed in the county's records.
Letting an insurance agent assign a "preferred" inspector who works under volume contracts. Volume inspectors are paid to move fast, not to claim every credit.
Not requesting a copy of the report yourself. The PDF should be in your hands the same day the inspection happens. If the inspector won't send it to you directly, that's a flag.
Failing to confirm your carrier actually applied the credits. Send the report. Then check your next bill. If the credits aren't there, push back — Florida law is on your side.

Frequently Asked Questions
How much does a wind mitigation inspection cost in Jacksonville?
Between $100 and $150 for most single-family homes in the Jacksonville market. Inspections take under an hour, and the inspector typically emails the completed OIR-B1-1802 to you and your insurance agent the same day. Eligible homeowners can also get the inspection performed free of charge through the state's My Safe Florida Home program.
How long is a wind mitigation inspection valid?
Five years from the date of the inspection. After five years, your carrier is no longer required to apply the credits, and you'll need a new inspection to maintain the discount. If you've made meaningful improvements during that window — a new roof, hurricane shutters, impact doors — re-inspecting earlier can capture additional credits sooner.
Can a wind mitigation inspection raise my insurance premium?
The wind mitigation inspection only documents the qualifying features your home has. If your home has features that earn credits, your premium goes down. If it has no qualifying features, your premium remains where it is — the inspection isn't used to add new charges. The downside risk of pulling a report is effectively zero. The OIR-B1-1802 is structured to identify discount-qualifying construction; it isn't an underwriting inspection used to flag adverse conditions.
Who can perform a wind mitigation inspection in Florida?
A Florida-licensed home inspector, general contractor, building contractor, roofing contractor, professional engineer, or architect can complete the OIR-B1-1802. The inspector must be authorized to sign the form under Florida law for your carrier to accept it.
Does a new roof automatically lower my insurance?
Not automatically. The credits don't apply until they're documented on a wind mitigation inspection and submitted to your carrier. A new roof can qualify for several credits, but if no inspection is on file, your carrier has no way to apply them. After any roof replacement, schedule a wind mit inspection within 60 days of permit closeout.
What if my home was built before 2002?
You can still earn meaningful credits. A retrofitted roof-to-wall connection, a new code-compliant roof covering, ring-shank deck fastening, and a hip-shaped roof can all be claimed regardless of the home's original permit date. The 2001 Florida Building Code credit alone won't apply, but the rest are still in play.
What is the OIR-B1-1802 form?
The Uniform Mitigation Verification Inspection Form, standardized by the Florida Office of Insurance Regulation. It's the only form Florida property insurers are required to accept for wind mitigation credits. The current version was updated effective April 2026 — older versions may still be accepted by some carriers but should be replaced at the next inspection.
What if my insurance carrier won't apply the credits?
Florida Statute 627.0629(1) requires every property insurer offering residential coverage in the state to include actuarially reasonable discounts for verified windstorm mitigation features in their rate filings. If your carrier refuses to apply credits that appear on your OIR-B1-1802, contact your agent first, then escalate to the Florida Department of Financial Services' Division of Consumer Services (1-877-MY-FL-CFO). Documented refusals to apply mandated credits are an enforcement issue handled by the state.
There's no good reason to overpay your insurance carrier in 2026. If your wind mit report is more than five years old, if you've never pulled one, or if you're about to install a new roof, the inspection is one of the cleanest financial wins available to a Jacksonville homeowner.
