What is Florida's 25% roof rule, and does it still apply in Brevard County?

The 25% roof rule once forced a whole roof up to current code when about a quarter was repaired. Since SB 4-D (2022), many newer roofs in Brevard County, Florida are exempt, but a permit is still required.

If you are buying or selling on the Space Coast, the roof is usually the biggest line item on the inspection report. For years, one rule made small roof repairs surprisingly expensive: repair too much of a roof, and the entire roof had to meet the current Florida Building Code. That rule changed in 2022, and a lot of homeowners and buyers in Brevard County still think the old version applies.

This guide walks through what the rule used to say, what SB 4-D changed, and what Brevard County requires before a roofer can start. It is written for buyers weighing an older roof and for sellers deciding whether to repair or replace before listing in Melbourne, Viera, Merritt Island, Cocoa Beach, or anywhere else on the Space Coast.

What Was the 25% Roof Rule in Florida?

Before May 2022, the Florida Building Code required that when more than 25% of a roof section was repaired, replaced, or recovered, the entire roof section had to be brought up to the current code. In practice, a storm that damaged a corner of a Brevard County roof could turn a repair into a full replacement, because the repair crossed the 25% line and triggered the upgrade.

That is why so many Florida roofing conversations include the phrase "25% rule." It affected repair bids, insurance claims, and the way sellers thought about patching a roof before a sale.

What Did SB 4-D Change for Roofs?

SB 4-D (titled "Building Safety") became Chapter 2022-269, Laws of Florida, and was approved on May 26, 2022. The Florida Senate bill summary says it provides that the roofing system or roof section of certain existing buildings does not have to be repaired, replaced, or recovered in accordance with the Florida Building Code under certain circumstances. The roof provision connects to section 553.844 of the Florida Statutes. The same bill also added milestone inspection requirements for certain condominium buildings, which matters for Space Coast condo buyers.

According to a Florida law firm summary of the change, the practical effect is this: if the existing roof complied with the 2007 Florida Building Code or any later edition, only the repaired, replaced, or recovered portion has to meet the current code, not the whole roof. That same summary notes the 2007 code took effect on March 1, 2009, so roofs built or replaced after that date generally qualify for the exception, while older roofs are more likely to still be pulled into the old rule.

Those are summaries, not legal advice. Whether a particular roof qualifies is a question for the building department and a licensed roofing contractor.

How Does the Roof Rule Affect a Brevard County Home Purchase?

Roof age is already a major factor for buyers on the Space Coast, and the rule change adds one more thing to ask about. When an inspection finds damage on an older roof, these are the questions worth asking:

  • When was the roof last replaced, and is there a permit on file for that work?
  • If the roof predates the 2007 code era, could a repair trigger more than a patch?
  • Do the repair bids you receive say whether the contractor expects the whole roof to be involved?
  • Does the seller have receipts, permits, and the supplemental fastener paperwork from the last re-roof?

Having the permit history in hand before you write an offer in Brevard County helps you compare a repair bid against a full replacement quote with real information.

What Does Brevard County Require to Repair or Replace a Roof?

Brevard County's Planning and Development department states that a permit is required for repair or replacement of roof covering, including shingles, tile, and metal, as well as skylights. Here is what the county's residential reroof page lists:

Item What the county says
Permit Required for repair or replacement of roof covering and skylights
Who can pull it Licensed professionals within their license type, or an owner/builder who appears in person
Supporting documents Subcontractor Authorization, Supplemental Fastener Affidavit, and product approval information on site
Notice of Commencement Required if the job value is over $5,000, recorded with the Clerk of Courts
Application fee $25.00 at submittal, plus $10.00 unlicensed contractor enforcement fee
Building code review $75.00 for the first $1,000 of job value, plus $3.25 per additional $1,000 or portion

As an example of the code review line only, a $12,000 roof comes to $75.00 plus 11 additional $1,000 increments at $3.25, which is $110.75. State surcharges and the application fees are added on top, and the county notes that fees are estimates that vary by project.

One important limit: the county's permit pages cover unincorporated areas of Brevard County. If a home sits inside a city, such as the city limits of Melbourne or Cocoa, the roofing permit is handled by that city, so confirm which office applies before you hire anyone.

Should Space Coast Sellers Repair or Replace Before Listing?

If the roof is on the newer side and was permitted, a targeted repair may be enough, and the 2022 change means a repair no longer automatically becomes a full replacement for roofs that qualify. If the roof is older, buyers in Brevard County will often ask for a replacement credit or a roof certification, so it helps to get a licensed roofer's written opinion before you list. Pull the permit history first, because a missing final inspection is easier to fix before you are under contract than after.

FAQ

Is the 25% roof rule gone in Florida?

Not entirely. SB 4-D limits the rule for roofs that already complied with the 2007 Florida Building Code or a later edition. Older roofs may still be treated under the original approach, so ask the building department about your specific roof.

Do I need a permit to repair a roof in Brevard County?

Brevard County states a permit is required to repair or replace roof covering in unincorporated areas. If your home is inside a city, check with that city's building department.

Can I pull my own roofing permit on the Space Coast?

Owner/builders can apply for the permit in Brevard County, but the county says they must personally appear to submit the application under Florida Statute 489.103 and file an Owner Builder Application for Contractor Exemption.
