A new roof can change your wind mitigation credit in Florida, but only when the replacement changes a roof item that the inspection form records. Roof covering, roof-to-wall connections and roof deck attachment are the items a replacement most directly touches. This guide explains what the form checks, how Florida building rules apply to a roof replacement<\/a>, and what to gather before you talk to your insurer. Our team serves homeowners across South Florida, including Miami, Kendall, Fort Lauderdale, West Palm Beach, Boca Raton, Naples and Fort Myers.<\/p>\n

What Is Wind Mitigation?<\/h2>\n

A wind mitigation inspection records the features that help a home resist hurricane winds. It’s completed on a uniform state form, and insurers use that form to apply a discount. Fla. Stat. \u00a7 627.711<\/a> says the Financial Services Commission develops a uniform mitigation verification inspection form that all insurers must use when policyholders submit it for wind-insurance discounts.<\/p>\n

The form checks several parts of the home. Those include roof covering, roof-to-wall connections, roof deck attachment, roof shape, opening protection and secondary water resistance.<\/p>\n

A roof project can touch several of these items at once. That’s why the roof section of the form deserves a close look before and after a replacement.<\/p>\n\n

Do I Need a Wind Mitigation Inspection in Florida?<\/h2>\n

Yes, if you want your insurer to apply a mitigation discount, the insurer needs a completed form. The inspection is what documents your home’s features for the insurer. The Florida Department of Financial Services guide<\/a> addresses qualified inspectors and the documentation behind these discounts.<\/p>\n

Under the same statute, an insurer must accept a form signed by an authorized mitigation inspector. That includes a home inspector licensed under s. 468.8314 who has at least 3 hours of hurricane mitigation training and has passed a proficiency exam.<\/p>\n

The inspection reflects the home on the day it’s done. A roof replacement changes the roof, so an older form may not describe the finished roof. The statute also says the Commission must provide guidance on how long inspection results stay valid. Ask your insurer which period applies to your form.<\/p>\n

Which Roof Details on the Form Can a New Roof Change?<\/h2>\n

Roof covering, roof-to-wall connections and roof deck attachment are the roof details a new roof is most likely to change. Each one ties to a specific part of Florida’s building rules.<\/p>\n

Roof covering.<\/strong> Florida law bars a roofing product from being advertised, sold, offered, provided, distributed, or marketed as hurricane, windstorm, or impact protection from wind-borne debris unless it is approved under s. 553.842 or s. 553.8425. Anyone who does so without that approval is subject to the Florida Deceptive and Unfair Trade Practices Act, in an action brought by the enforcing authority as defined in s. 501.203. Fla. Stat. \u00a7 553.842<\/a> lists roofing among the product categories that require this approval. Keep the product approval paperwork with your roof records.<\/p>\n

Roof-to-wall connections.<\/strong> Fla. Stat. \u00a7 553.844<\/a> lists prescriptive techniques for improving roof-to-wall connections. The statute also limits when they are required. Roof-to-wall connections are not required unless gable-end or all-corner work can be completed for 15 percent of the cost of the roof replacement.<\/p>\n

Roof deck attachment.<\/strong> The same statute lists strengthening or correcting roof-decking attachments and fasteners during reroofing. That makes deck fastening a point a replacement must address directly: under the statute, replacing the roof on a site-built single-family home calls for roof-decking attachment and fastener techniques, while roof-to-wall connections are required only if gable-end or all-corner reinforcement can be completed for 15 percent of the roof replacement cost.<\/p>\n

Roof shape.<\/strong> Shape is part of that review, so keep the roof plans with your records.<\/p>\n

A common mistake is assuming any roof job changes the credit. A small repair may not touch these items. A full replacement is more likely to.<\/p>\n

Does a New Roof Change the Wind Mitigation Credit?<\/h2>\n

A new roof can change the credit, but only when the new roof changes an item the form records. The credit itself is set by the insurer’s rating, not by the roof alone.<\/p>\n

Florida’s windstorm discount rule requires the discounts to reflect the state’s mitigation forms. Fla. Admin. Code R. 69O-170.017<\/a> says the discounts must reflect Forms OIR-B1-1699 and OIR-B1-1700. They must be used without modification unless detailed alternate studies, where all assumptions are available to the Office for review, support a change. The insurer works from that standard structure, not a custom number for your roof.<\/p>\n

A roof installed to current code can document stronger roof-to-wall connections and deck attachment than an older roof did. Whether that changes your credit depends on the facts of your roof and your insurer’s rules. No one can promise a particular credit or premium from a roof project.<\/p>\n

How the Florida Building Code Applies to Roof Replacement<\/h2>\n

The Florida Building Code governs roof replacement work. Fla. Stat. \u00a7 553.73<\/a> says the code contains the laws and rules that govern the repair and alteration of buildings. Fla. Stat. \u00a7 553.73<\/a> provides that the commission shall adopt an updated Florida Building Code every 3 years.<\/p>\n

Unless otherwise provided by law, Fla. Stat. \u00a7 553.79<\/a> bars any person from altering, modifying, or repairing a building in this state without first obtaining a permit from the appropriate enforcing agency. Miami-Dade County publishes its roofing permit requirements<\/a>, including forms, checklists and certain hurricane-mitigation documentation.<\/p>\n

The permit and inspection record show what was installed, which supports the updated form.<\/p>\n

Impact windows and doors are a separate part of the home. Fla. Stat. \u00a7 553.842<\/a> requires statewide approval for windows, exterior doors and impact protective systems. Adding or strengthening opening protections is also a mitigation technique under Fla. Stat. \u00a7 553.844<\/a>.<\/p>\n

What to Gather Before a Roof Review<\/h2>\n

Gather your current wind mitigation form, your policy declarations page and your roof paperwork before you call your insurer. Those documents show what your credit is based on and what has changed.<\/p>\n

Start with the existing mitigation form and the declarations page that shows your current credit. Then collect the roof replacement contract, the permit record and the product documentation for the roof covering.<\/p>\n

Write down any change to the roof deck, the fasteners or the roof-to-wall connections. Note the dates of the work as well. A clear, dated list makes the review faster and easier to follow.<\/p>\n\n

How Form Updates Affect Roof Entries<\/h2>\n

The wind mitigation form has been revised, so an inspection done on an older version may not match the current form. The current uniform form is OIR-B1-1802, listed with a revision date of 04\/26 in Fla. Admin. Code R. 69O-170.0155<\/a>. Under the same rule, insurers submit information from these forms to the Office within 60 days after the later of a rate-change effective date or the policy’s effective date.<\/p>\n

Roof entries should match the roof as it is installed today. That includes the covering, the connections and the deck attachment. An entry that describes the old roof can misstate the home after the work is done.<\/p>\n

Ask your inspector which form version they will complete. Ask them to record the roof items as they are now.<\/p>\n\n

Quick Answers<\/h3>\n
Does a new roof change my wind mitigation credit?<\/summary>

It can, but only if the new inspection records a different roof item. The insurer sets the final credit.<\/p><\/details>

Do I need a permit to replace a roof in Miami-Dade?<\/summary>

Florida law generally requires a permit before repairing or altering a building. Miami-Dade publishes its roofing permit requirements online.<\/p><\/details>

Do impact windows count toward the credit?<\/summary>

Opening protection is a separate item from the roof itself, so windows and doors are documented apart from the covering.<\/p><\/details>

How long is a wind mitigation inspection valid?<\/summary>

The Financial Services Commission provides guidance on that period, so confirm it with your insurer.<\/p><\/details>\n\n<\/article>\n
