Key Takeaways:
- Florida’s 25% roofing rule generally requires broader code compliance when more than 25% of an existing roof or roof section is repaired, replaced, or recovered within a 12-month period.
- An important exception applies to qualifying roofs that were previously built, repaired, or replaced in compliance with the 2007 Florida Building Code or a subsequent edition; in those cases, the entire roof does not automatically have to be replaced solely because work exceeds 25%.
- Whether the rule applies depends on the roof’s permitting/code-compliance history and the scope of the proposed work, so homeowners should confirm requirements for their specific property before beginning repairs.
The roofing industry and the home insurance companies that provide coverage for many roof repairs and replacements have many different laws regarding what can be covered, what actions either roofers or insurance providers need to take, and how homeowners can protect their homes. Homeowners can best leverage their insurance coverage and protect their properties from water damage and leaky roofs by staying up to date on changes in the surrounding laws, including Florida’s roof replacement law regarding 25% damage. Learn more about the changes and how they can impact your finances.
What Is Florida Building Code 25%?
Florida Building Code 25%, or the Florida roof replacement law, was originally enacted to protect homeowners. In the event that a covered residential roof sustained damage of 25% or more from a qualifying event, the roof had to be repaired or replaced in its entirety to comply with state building codes. Lawmakers put this rule into effect because patches only work on small, isolated bits of damage, and if too much of a roof is made from patchwork solutions, the roof becomes less structurally sound. Patches over time might also delay replacement, meaning you would have a roof that falls further and further away from current building codes. This rule means insurance providers have to cover the applicable costs when roof damage triggers the rule.
This provision is even more important in states like Florida, where roofs regularly undergo severe weather events like hurricanes and tropical storms. High humidity, sunny skies, and harsh temperatures also lead to roof degradation. The 25% roof replacement rule does double-duty: it can help stop small but significant damage from accruing over time in tangentially damaged spots, and it can make sure you have a newer and sturdier roof to take on hurricane-level storms than you might otherwise have.
Florida Building Code 25% Reroofing Rule
Florida Building Code – Existing Building §706.1.1 establishes what roofers must do to create, repair, or modify roofs to meet state-wide requirements. Under this provision, roofs permitted before March 1, 2009, are subject to the 25% roofing rule and must be fully repaired or replaced if they take on enough damage to warrant repairs or replacement of over 25% of the roof over 12 months. But for roofs permitted and closed out after this point, the 25% rule does not apply.
How did this change in the Florida roof replacement law come into place? In 2022, Governor DeSantis signed SB4D. Under this law, roofs that were built or replaced to comply with the 2007 Florida Building Code don’t qualify for the rule. Even if damage exceeds 25% of the roof, only the damaged area needs to be repaired or replaced. This largely applies to roofs built after 2009.
Some additional Florida roofing law changes in 2025 include:
- Stricter rules for what insurance companies must cover when repairs are made to older roofs
- Stringent inspection standards, especially in areas more vulnerable to hurricanes
- New standards for roofing materials
Florida Building Code 25% Rule Decision Path
Determining whether the 25% roof replacement rule applies to a property is relatively simple. Inspectors and homeowners can use this quick decision tree to determine if they need to invoke the Florida law for roof replacement:
- Was the current roof permitted after March 1, 2009?
- If yes, only the damaged area needs repairs and replacement, and insurance providers will provide funds based on the event and the terms of the insurance.
- If no, will the roof need repairs or replacements that exceed 25% of the roof (including any other repairs or replacements done within the twelve-month period)?
- If yes, the entire roof will require repairs and replacement, and the insurance provider may need to cover the entire cost.
- If not, only the damaged area requires repairs and replacement.

Frequently Asked Questions
Does Florida’s 25% roof rule mean I have to replace my entire roof?
Not necessarily. Florida law provides an important exception for an existing roofing system or roof section that was built, repaired, or replaced in compliance with the 2007 Florida Building Code or a subsequent edition. When that exception applies, repairing, replacing, or recovering 25% or more does not, by itself, require the remainder of that roof or roof section to be brought up to the current code.
Which roofs are exempt from Florida’s 25% roof replacement requirement?
Under current Florida law, if an existing roofing system or roof section was built, repaired, or replaced in compliance with the 2007 Florida Building Code or a subsequent edition, only the portion being repaired, replaced, or recovered is required to comply with the applicable current code when 25% or more is involved. Property owners should verify their roof’s code and permit history before assuming the exception applies.
Does the 25% rule apply to roof repairs completed within the same 12-month period?
The Florida Building Code’s reroofing provisions use a 12-month period when evaluating the amount of a roof or roof section being repaired, replaced, or recovered. However, the statutory exception for roofing systems compliant with the 2007 Florida Building Code or later can change the result. Because applicability depends on the specific roof and work being performed, confirm the requirements with the local building department or a qualified roofing professional.
How do I find out which Florida Building Code my roof was installed under?
Start by locating the permit records for the roof installation or most recent replacement through your local building department or permitting authority. The permit date and related records can help establish when the work was performed and the applicable code requirements. If the records are unclear, the local building department can help determine what documentation is needed.
