Understanding Wind Mitigation and Insurance in Florida

A homeowner's guide to wind mitigation inspections in Florida — what inspectors generally evaluate, how the OIR-B1-1802 form works, and how homeowners typically work with their insurer.

Wind mitigation is one of the more frequently discussed topics in Florida homeownership, particularly in conversations about property insurance. For homeowners new to the state — or simply new to the topic — the terminology can be confusing. What does a wind mitigation inspection actually look at? How is that information used? And how does it factor into conversations with an insurance agent?

This guide provides a general overview of the category so homeowners can have more productive conversations with licensed wind mitigation inspectors and their insurance professionals. It does not recommend specific improvements, guarantee premium outcomes, or suggest that any particular feature is required for any property.

What Wind Mitigation Means in a Florida Context

"Wind mitigation" is a broad term that refers to construction features and building characteristics that may affect how a structure performs during high-wind events, including hurricanes and tropical storms. In Florida, the concept has particular relevance because of the state's exposure to Atlantic and Gulf storm systems.

Over the years, Florida has developed a framework for documenting wind-resistant features on existing homes. This framework is used by many insurers operating in the state when they underwrite property policies. A wind mitigation inspection is the process by which a qualified inspector documents these features on a specific home.

It is important to understand what a wind mitigation inspection is not. It is not a safety certification, a guarantee that a home will withstand a storm, or a statement that a property meets any particular building code. It is a documentation exercise that records what features are present on a property at a point in time.

The OIR-B1-1802 Form

Much of the conversation around wind mitigation in Florida centers on a standardized form known as the OIR-B1-1802 [VERIFY], which is associated with the Florida Office of Insurance Regulation (OIR). The form, used by many Florida insurers, documents several categories of features an inspector assesses on a residential property.

The form generally groups features into categories such as the age of the roof covering, roof shape, roof deck attachment, roof-to-wall connection, secondary water resistance, and opening protection. An inspector reviewing a property walks through each section and records what is observed, often with supporting photographs.

The form itself, and the way insurers use its content, can change over time. Homeowners should not assume that a form from several years ago reflects the current version or that the same information will be interpreted the same way by every insurer. An insurance agent can confirm what is current for a specific policy.

Categories a Wind Mitigation Inspector Typically Looks At

The following sections describe — at a general level — the categories an inspector commonly evaluates. This is intended to help homeowners follow along during an inspection and read the resulting report, not to advise on what any property should or should not have.

Roof Shape

Roof shape refers to the overall geometry of the roof as seen from above. Common shapes on Florida homes include hip roofs (which slope down on all sides), gable roofs (with two sloping sides and vertical end walls), and combinations of the two. Inspectors typically document which shape predominates on the home. The shape of a roof is a fixed architectural feature on most homes and is generally not something that changes without significant construction.

Roof Covering

Roof covering refers to the outer material layer — for example, asphalt shingles, metal panels, tile, or other systems. Inspectors generally document the type of covering, its approximate age, and information about its product rating where that information is available. Product ratings and testing standards vary by material and manufacturer, and the relevant standards change over time. A licensed contractor or inspector can speak to what is current for a specific product.

Inspectors do not, as part of a wind mitigation inspection, certify that a roof covering "meets code" or "is compliant." Those determinations are made by local building officials during the permitting and inspection process, and requirements vary by jurisdiction.

Roof Deck Attachment

The roof deck is the layer of wood sheathing beneath the roof covering. Roof deck attachment refers to how that sheathing is fastened to the underlying framing — for example, the type and spacing of nails or other fasteners. Inspectors typically attempt to document this from the attic, where the underside of the deck is visible.

Roof-to-Wall Attachment

Roof-to-wall attachment refers to the connection between the roof structure (trusses or rafters) and the walls of the home. Common connection types include toe-nailed connections, clips, single wraps, and double wraps, among others. Inspectors generally document what they are able to observe, typically in the attic space.

Because these connections are often concealed within the wall and roof assembly, inspectors may only be able to document what is visible. If connections cannot be verified visually, the inspector will generally note that on the form.

Secondary Water Resistance

Secondary water resistance refers to a layer of protection beneath the primary roof covering intended to limit water intrusion if the covering is damaged. Whether a home has this feature, and what form it takes, depends on how the roof was installed. Inspectors document what is present based on the information available to them, which may include permit records, photographs taken during installation, or visible evidence.

Opening Protection

Opening protection refers to features that protect windows, doors, garage doors, and other openings from wind-borne debris. Examples include impact-rated glazing, shutters, and protective panels. Inspectors typically document the type of protection present, whether it covers all openings or only some, and relevant product information where available.

Different insurers may treat partial protection differently than full protection. An insurance agent can explain how a specific policy considers these distinctions.

How the Inspection Fits Into the Insurance Conversation

A wind mitigation inspection report is ultimately a document that is provided to an insurer. How the insurer uses that information — and how it affects a policy — depends on the insurer, the policy, and the specific features documented.

Many Florida homeowners report reduced insurance premiums after wind mitigation improvements, though actual savings vary by insurer, location, and policy. Some insurers may offer credits or adjustments related to specific documented features, but the structure, availability, and magnitude of those considerations vary widely and change over time. There is no single industry-wide schedule of credits that applies to every insurer or every policy.

For that reason, homeowners are generally better served by asking their insurance agent directly how a specific feature would factor into a specific policy, rather than relying on general estimates from outside sources.

It is also worth noting that the Florida insurance market has gone through significant changes in recent years. Policy availability, underwriting standards, and the specific features insurers emphasize have all shifted at various points. An insurance agent can speak to what is current.

Choosing a Wind Mitigation Inspector

Wind mitigation inspections in Florida are generally performed by individuals in certain licensed categories, which can include licensed home inspectors, licensed general or residential contractors, licensed roofing contractors, and certain licensed engineers and architects [VERIFY]. The specific categories authorized to perform wind mitigation inspections, and any documentation or training requirements, are governed by state rules that change over time.

Homeowners can verify an inspector's credentials through the Florida Department of Business and Professional Regulation (DBPR) and should confirm with their insurer that the chosen inspector's documentation will be accepted. Some insurers have specific requirements or preferred processes.

Useful questions for a prospective inspector often include:

What is your licensing or certification for performing wind mitigation inspections in Florida?
Have you performed inspections that have been accepted by my insurer before?
What will the inspection cover, and what documentation will I receive?
How long is the inspection report generally considered current by insurers?
If you cannot visually verify a feature, how is that handled on the report?

Talking With Your Insurance Agent

Because so much of how wind mitigation affects a policy depends on the specific insurer, a conversation with the insurance agent is often the most productive starting point. Useful questions for that conversation include:

Does my policy consider wind mitigation features, and if so, which ones?
What documentation do you need from an inspector, and in what format?
How often should a wind mitigation inspection be updated for my policy?
If I am considering a change to my roof or openings, can you explain how documented features on the current inspection report compare to what a new report might show?
Are there any specific inspectors, forms, or processes you require or prefer?

The answers to these questions will be specific to a given insurer, a given policy, and a given property. Your contractor and insurance agent can help you evaluate whether a specific change makes sense for your situation.

Working With a Roofing Contractor on Wind-Related Topics

Wind mitigation often comes up in conversations with roofing contractors, particularly during re-roof projects or major repairs. When a roof is being replaced, certain features may be documented or installed as part of the project, and those features may be relevant when a new wind mitigation inspection is performed.

A licensed roofing contractor can explain what is involved in a specific project, what product and installation information will be documented, and how the project relates to the permitting and inspection process in the local jurisdiction. Requirements vary by jurisdiction and change over time, and your local building department and contractor can confirm what applies.

Homeowners who are considering a roofing project and who also want to understand wind mitigation implications often find it helpful to loop in their insurance agent during the planning stage, so that the contractor, agent, and inspector are all working from the same expectations.

What to Keep Realistic

A few general points are worth keeping in mind:

A wind mitigation inspection documents features; it does not certify safety or predict storm performance.
Premium effects are insurer-specific and change over time. General numbers from outside sources may not reflect a specific policy.
Building codes, product standards, and inspection rules change. Information from a few years ago may not reflect the current framework.
A wind mitigation inspection is not a substitute for a home inspection, a roof inspection by a licensed roofing contractor, or guidance from an insurance professional. Each of those services addresses a different question.
