Florida Wind Mitigation Improvements

In Florida, wind mitigation refers to construction characteristics that affect how a home is expected to perform in high wind. Rather than being assessed informally, those characteristics are documented on a standard statewide form — the Uniform Mitigation Verification Inspection Form, commonly referenced as OIR-B1-1802 — so that every inspector records the same items in the same way.

Two things follow from that. First, wind mitigation is mostly about what your house already is: its age, roof shape, construction and any previous work. Second, improving a mitigation feature and having it documented are separate steps — work that is never recorded on an inspection is, from the paperwork's point of view, invisible.

This page is general education. It is not an insurance, code or engineering opinion, and it does not restate the current contents of the state form. Check the official sources listed at the end for anything current.

A wind mitigation inspection is a targeted look at a defined list of items rather than a general home inspection. The items span the roof and the openings, which is why it cuts across the topics covered on our service guides:

• Building code compliance context — broadly, when the home was built or when the roof was permitted.
• Roof covering and its permitting history.
• Roof deck attachment.
• Roof-to-wall connections.
• Roof geometry.
• Secondary water resistance.
• Opening protection, including windows, doors, skylights and the garage door.

The sections below explain each of these in homeowner terms. Where the underlying construction deserves a fuller treatment, we link rather than repeat.

This item concerns the visible covering — shingles, tile, metal — and the permitting history behind it. An inspector is generally looking at what the covering is, when it was installed and whether that installation was permitted.

One consequence worth knowing in advance: work done without a permit, or a permit never closed, can complicate documentation later. For how covering choices, condition and replacement decisions work in Florida, see the roofing guide.

The roof deck is the sheathing that sits on the framing and carries the covering. Deck attachment describes how that sheathing is fastened down — the type of fastener and how closely spaced it is. It matters because uplift acts on the deck, and a deck that stays put keeps the building envelope closed.

This is generally only accessible during a re-roof, when the covering is off. That timing is the practical reason so many mitigation improvements are made as part of a roof replacement rather than as a standalone project.

These are the metal straps, clips and connectors that tie the roof framing to the walls. Homeowners often hear them called hurricane straps or hurricane clips. Their job is to resist uplift and lateral force where the roof meets the structure.

What a particular home has depends on how and when it was built. Retrofitting connections in an existing house is possible in some cases but is real structural work, with access typically from the attic, and it is not a routine add-on to an unrelated project. The roofing guide covers how this comes up in practice during a roof replacement.

Roof shape — hip, gable or a combination — is recorded because shape affects how wind loads a roof. Unlike the other items, this one is essentially fixed. Changing a roof's geometry is a structural redesign, not a mitigation improvement, and it is not something a re-roof normally does.

For most homeowners this is a fact to be documented rather than a decision to be made.

Opening protection covers windows, exterior doors, sliding glass doors, skylights and the garage door. What the inspection is concerned with is whether protection is an approved system and whether it covers the openings — not whether a product was marketed as hurricane-related.

• Both impact-rated products and approved shutter systems can satisfy opening protection.
• Protection is generally considered across the openings as a set, so partially protected homes are documented differently from fully protected ones.
• The garage door is an opening like any other, and an unrated garage door can be the weak point on an otherwise protected house.
• Approval documentation and labels are what let an inspector verify a product, so keep them.

For the product side of this in depth, see Impact Windows & Doors, or Impact Windows vs. Hurricane Shutters if you are choosing between approaches.

Secondary water resistance is an additional barrier applied to the roof deck, intended to slow water entering the home if the covering is damaged or lost. Its purpose is water control rather than structural strength, which is why it is listed separately from deck attachment.

Like deck attachment, it is applied during a re-roof and not added afterward. If it matters to you, it needs to appear in the written roofing scope before the work starts.

The garage door deserves its own mention because it is usually the largest opening in the house and is frequently the one homeowners forget. Wind-rated doors are approved as a complete assembly — door, track and hardware — and bracing systems exist for some existing doors where the manufacturer and building department accept them.

A wind-rated door installed with the original unrated track is not the approved assembly, so ask what exactly is included in any proposal.

A wind mitigation inspection is a short visit — commonly involving the exterior, the attic where accessible, and photographs of each documented feature. The output is the completed state form, signed by the inspector, which you can then provide to your insurer or agent.

• Inspections are performed by qualified inspectors as defined by state requirements; who qualifies is set by the state, not by us.
• The inspector documents what exists — they are not a contractor and do not make improvements.
• Attic access matters: features that cannot be observed generally cannot be documented.
• Reports have a validity period for insurance purposes, so an old report may need to be redone.
• Keep permits, product approval numbers and photos from past work; they make documentation far easier.

The My Safe Florida Home program has at times offered free inspections to eligible homeowners. Availability, funding and eligibility are set by the state and change over time, so check the official program site directly.

Florida insurers may consider documented mitigation features when rating a property. That is the accurate and complete statement. What it produces for any individual property depends on the insurer, the policy, the property, the documentation and the inspection itself.

• No specific improvement guarantees a discount, and no contractor or matching service can promise one.
• An improvement that is not documented on an inspection is unlikely to be reflected anywhere.
• Insurers weigh the recorded features differently, so two carriers may treat the same report differently.
• Talk to your insurer or agent before a project so you know which documentation they would want.
• The state insurance regulator publishes consumer guidance on this at Florida OIR wind mitigation resources.

Given that roof geometry and construction era are fixed, the realistic scope for improvement is narrower than homeowners often expect. Most of it clusters around two projects:

• At re-roof time: deck attachment, secondary water resistance and the covering itself, all of which are accessible while the roof is off.
• Retrofitting roof-to-wall connections, which is structural work usually approached separately and where attic access governs feasibility.
• Adding or completing opening protection, including any openings that were skipped in an earlier phase.
• Replacing or bracing the garage door with an approved assembly.
• Having an up-to-date inspection performed once work is complete, so the improvements are actually recorded.
