Key takeaways
- Florida insurers are required to offer premium discounts based on wind mitigation features, recorded on the standardized OIR-B1-1802 inspection form.
- The inspection checks roof covering, roof deck attachment, roof-to-wall attachment, roof shape, secondary water resistance, and opening protection.
- A hip roof typically qualifies for a larger geometry credit than a gable roof because it performs better against high wind.
- Impact-rated windows, doors, and shutters that protect every opening can produce one of the larger available credits.
- Wind mitigation inspection results are generally valid for five years, so it's worth re-inspecting after that period or after major roof or window work.
- Only a licensed inspector, contractor, engineer, architect, or building code official can legally complete and sign the form for insurance purposes.
If you own a home in Palm Coast, a wind mitigation inspection is one of the more reliable ways to lower your windstorm premium without changing carriers. Florida requires insurance companies to give credits for specific, verifiable construction features that reduce hurricane wind damage, and those features are documented on a standardized state form. Understanding what the inspector actually checks, and what each category is worth in general terms, helps you know what to expect and whether an inspection is likely to pay off for your specific home.
What the OIR-B1-1802 form covers
The Florida Office of Insurance Regulation's wind mitigation inspection form, commonly referred to by its form number, OIR-B1-1802, is the standardized document insurers use to apply wind mitigation credits consistently across the state. A licensed inspector visits the home, examines specific construction details (mostly in the attic and on the roof), and records findings in six main categories.
| Category | What it checks | Why it matters |
|---|---|---|
| Roof covering | Type and age of roof material, and whether it meets current Florida Building Code wind-resistance testing standards | Newer, code-compliant roof coverings are less likely to fail or lose shingles/tiles in high wind |
| Roof deck attachment | How the plywood or OSB roof deck is fastened to the roof trusses (nail spacing and pattern) | Stronger fastening patterns keep the roof deck attached during extreme wind, reducing catastrophic roof loss |
| Roof-to-wall attachment | The type of connector between the roof structure and the walls (toe nails, clips, single wraps, or double wraps) | Hurricane straps or clips resist the roof being lifted off the walls, a major failure mode in high wind events |
| Roof geometry | Overall roof shape, primarily whether it is hip, gable, or a combination | Hip roofs perform better aerodynamically in high wind than gable roofs, which are more prone to wall and roof failure |
| Secondary water resistance (SWR) | Whether a self-adhering membrane or foam adhesive is installed under the roof covering as a backup barrier | Limits water intrusion into the home if the primary roof covering is damaged during a storm |
| Opening protection | Whether windows, doors, garage doors, and skylights are impact-rated or protected by rated shutters | Protects the building envelope and helps prevent internal pressurization that can blow off a roof |
How the credits generally work
Each category can qualify for a credit, and the credits generally stack, meaning a home with strong ratings across several categories usually sees a larger total premium reduction than a home that qualifies in only one or two areas. The exact dollar or percentage value of each credit varies by insurance company and by the specific rating factors filed with the state, so it is not accurate to quote a universal discount amount here. In general terms, though, some patterns hold across most Florida windstorm markets.
- Roof-to-wall attachment tends to carry a meaningful credit, since this connection is one of the most common failure points in older homes built with only toe-nail connections.
- Roof deck attachment credits are typically larger when nail spacing is tighter and ring-shank nails are used rather than smooth or staple fasteners.
- Roof geometry credits are usually larger for a full hip roof than for a gable or combination roof, reflecting the aerodynamic advantage of a hip design.
- Opening protection credits are typically largest when every opening on the home, including garage doors and skylights, is impact-rated or shuttered, rather than only some openings.
- Secondary water resistance credits are smaller individually but still contribute to the total, since they mainly reduce water damage risk rather than structural failure risk.
How to get an inspection in Palm Coast
The inspection must be performed by someone qualified under Florida law to complete the form for insurance credit purposes. This includes licensed home inspectors, general or building contractors, professional engineers, architects, and certain building code officials, among others specified in statute. Many Flagler County-area inspection companies offer wind mitigation inspections as a standalone service, often combined with a four-point inspection if your home is older, since insurers may request both around the same time.
- 1Confirm your inspector holds one of the qualifying licenses or credentials under Florida law before scheduling.
- 2Schedule the inspection with access to the attic, roof, and all exterior openings, since the inspector needs to physically verify roof deck attachment and roof-to-wall connections, not just visually estimate them.
- 3Ask the inspector to photograph the specific attachment details (nail patterns, straps or clips, permit tags if visible) since insurers may request supporting documentation.
- 4Request the completed OIR-B1-1802 form promptly after the inspection; you will need to submit it to your insurance agent or carrier to apply for credits.
- 5Provide the form to your agent at your next renewal, or ask whether your current carrier will apply a mid-term adjustment once the form is submitted.
- 6Keep a copy of the form and any supporting photos with your insurance records for future renewals or if you switch carriers.
Five-year validity and when to re-inspect
A completed wind mitigation inspection is generally valid for five years from the inspection date, after which most insurers will require a new inspection to keep applying the credits. You should also consider a new inspection sooner than five years if you replace your roof, add impact windows or shutters, or make other structural changes that could improve your rating in any of the six categories, since an updated inspection could increase your credits even before the five-year period expires.
Is the inspection worth the cost for every home
For most homeowners in Flagler County, the potential premium savings from qualifying credits are worth the one-time inspection fee, particularly for homes with a hip roof, a recently replaced roof, or any impact-rated openings already installed. Homes that are older, have a gable roof with toe-nail connections, and lack impact protection may still qualify for some credits, such as for roof covering type, but the overall savings may be more modest. Your agent can typically give you a sense of whether an inspection is likely to be cost-effective for your specific home before you schedule one.
Frequently asked questions
Who is allowed to perform a wind mitigation inspection in Florida?+
Florida law limits who can sign the OIR-B1-1802 form for insurance credit purposes to specific qualified professionals, including licensed home inspectors, contractors, engineers, architects, and certain building code officials. Always confirm your inspector's credentials before scheduling, since an unqualified inspection may not be accepted by your insurer.
How much money will a wind mitigation inspection actually save me?+
The exact savings depend on your specific insurer's filed rating factors and how many categories your home qualifies for, so there is no universal dollar figure. Homes with strong roof-to-wall connections, a hip roof, and impact-rated openings across the board tend to see the largest combined credits.
How long does a wind mitigation inspection take?+
Most inspections take roughly 30 minutes to an hour depending on attic accessibility and the size of the home. The inspector needs clear access to the attic and around the full exterior to verify the roof-to-wall connections and opening protection.
Do I need a new inspection every year?+
No, a completed inspection is generally valid for five years, so you do not need to repeat it annually. You should consider a new inspection sooner if you replace the roof or add impact-rated windows, doors, or shutters, since those changes could increase your credits.
Can a wind mitigation inspection ever raise my premium?+
The inspection itself does not raise your premium; it can only document features that qualify for credits under your carrier's filed rating plan. In practice, if a home has none of the qualifying features, the result is simply no additional credit rather than a penalty, so there is little downside to getting one inspected.
