If you’re a homeowner in Florida, you may have heard of the “25% rule” when it comes to roofing. This rule refers to the requirement that if more than 25% of your roof is damaged, it must be replaced in accordance with the Florida Building Code. In this article, we’ll take a closer look at what this rule means for homeowners and how to ensure that you’re in compliance.

What is the 25% Rule?

The 25% rule is a provision in the Florida Building Code that requires roofs to be replaced if more than 25% of the roof surface is damaged or needs repair. This rule applies to both residential and commercial buildings and is designed to ensure that roofs are structurally sound and able to withstand Florida’s harsh weather conditions.

What Does “Damage” Mean?

Under the 25% rule, “damage” refers to any wear and tear or other issues that compromise the integrity of the roof. This can include missing shingles, cracked tiles, leaks, or other signs of damage that indicate that the roof is no longer able to perform its intended function. In some cases, damage may not be visible from the ground, and a professional inspection may be required to determine whether the 25% threshold has been met.

Why is the 25% Rule Important?

In Florida, roofs are subjected to a wide range of weather conditions, including high winds, heavy rain, and intense sunlight. Over time, this can cause damage to the roof, which can compromise its ability to protect the building and its occupants. The 25% rule is designed to ensure that roofs are replaced when they reach a certain level of damage to prevent safety hazards and costly repairs down the line.

How to Ensure Compliance with the 25% Rule

If you suspect that your roof may be damaged and approaching the 25% threshold, the first step is to contact a professional roofing contractor to perform an inspection. They will be able to assess the extent of the damage and provide recommendations for repair or replacement.

If replacement is necessary, it’s important to choose a contractor who is licensed and insured and who has experience working with the Florida Building Code. They will ensure that the new roof is installed according to the code and will be able to provide documentation of compliance.

Changes to the 25% Rule

On May 26th, 2022, SB 4-D took effect which changed the 25% rule so that if your roof was constructed or replaced after March 1st, 2009, your roof most likely complies with the 2007 Florida Building Code, so instead of having to replace your entire roof if more than 25% of it was damaged you will only have to repair the portion that was damaged. Effectively if your home was built before March 1st, 2009 and you haven’t replaced your roof, you will still be subject to the 25% rule and will have to replace your entire roof if more than 25% of it is damaged.
