- Description: The Florida Building Commission approved Supplement 1 to the 9th Edition code on Oct. 13. It revises drip edge, steel-deck insulation and stainless fastener rules, adds a $7,500 single-family permit exemption and a five-day roofing permit clock, ahead of the Dec. 31 effective date.

Florida’s next building code just got its last big round of edits before it takes effect. At its Oct. 13 plenary session, the [Florida Building Commission](https://www.floridabuilding.org/fbc/commission/FBC%5F1026/index.htm?ref=ridgereport.news) took up the updated workplan for the 9th Edition (2026) Florida Building Code, and the commission’s posted [Supplement 1 to the 9th Edition](https://www.floridabuilding.org/fbc/thecode/2026%5FCode%5FDevelopment/Supplement%5F1%5Fto%5Fthe%5F9th%5FEdition%5Fof%5Fthe%5FFBC.pdf?ref=ridgereport.news) is labeled “Approved by the Commission – October 13, 2026.” The 9th Edition becomes effective Dec. 31, 2026, according to [Miami-Dade County’s product approval notices](https://www.miamidade.gov/global/economy/board-and-code/product-approval-notices.page?ref=ridgereport.news).

For roofers, the supplement does two things. It rewrites a handful of Chapter 15 roof provisions, including drip edge and steel-deck insulation, and it writes several permit changes from state law into the code, including a $7,500 permit exemption for some single-family work and a five-business-day review clock for small residential roofing permits. Those land on top of the roofing changes already in the 9th Edition: new wind rules for hip and ridge shingles, uplift testing for metal hip and ridge covers, and corrosion-resistant fasteners near salt water.

What it means for your crew

- Permits submitted on or after Dec. 31 fall under the 9th Edition. If a Florida job is close to that line, know which code your permit will be reviewed under.
- Hip and ridge shingles will need a label showing they passed UL 2375 at 110 mph, or you can use the prescriptive method: two 1-inch spots of roof cement on each side of the hip or ridge under every cap, plus the manufacturer’s fasteners.
- Within 3,000 feet of a saltwater coastline, fasteners and connectors have to meet the new corrosion table. Check what’s in the truck before the code changes, not after the inspector does.
- The supplement’s revised drip edge text calls for a 3-inch lap, fastening at 4 inches on center maximum, and drip edge installed over the underlayment. Read the full section to confirm which roof systems it governs before changing your standard details.

## The roof changes in Supplement 1

**Drip edge.** The supplement revises Section 1507.17.9.1 to require drip edge at eaves and gables of steep-slope roofs, defined there as 2:12 and above. Drip edge must be lapped at least 3 inches. Eave drip edge must extend 1/2 inch below the sheathing and at least 2 inches back onto the roof. It goes over the underlayment, though self-adhering underlayment meeting ASTM D1970 is allowed over a primed drip edge flange. Fastening is 4 inches on center maximum.

**Steel decks.** Revised Section 1519.7 says steel decks must be covered with a roof insulation panel that has its own product approval and is listed in the roofing assembly’s product approval. Panels must be mechanically fastened using the attachment patterns in that assembly approval and following RAS 117.

**Stainless fasteners.** Section 1711.1.1.1, which sets the stainless grades for the saltwater corrosion table, now lists ASTM A240 Type 304, 305, 316 or 410 stainless. The supplement also rewrites the table’s exposure definitions, from “exterior-partially sheltered” to “unconditioned interior-unvented enclosed.” The residential code’s matching section, R332.1.1.1, gets the same Type 410 addition.

**HVHZ protocols.** In the test protocols for the High-Velocity Hurricane Zone, the supplement revises RAS 117 Section 6.2 on rigid insulation over lightweight concrete decks and rewrites the scope of TAS 114, the test procedure for roofing assemblies in the zone.

## The permit changes

Several Chapter 1 edits matter as much to a roofing office as the technical ones. Under the supplement’s new Section 105.2.3, a local government that issues building permits must exempt the owner of a single-family home, or the owner’s contractor, from getting a permit for work valued under $7,500\. The exemption doesn’t apply in a flood hazard area or to electrical, plumbing, structural, mechanical or gas work. To use it, the owner or contractor has to send the local building department a written request with a copy of the contract or other proof of what the work is and what it’s worth. A project can’t be split up to get under the limit.

Roofing is not on the supplement’s list of excluded work. But the exemption turns on a written request and the value in the contract, and the local government has no legal duty to the owner or contractor for exempted work. Check with each building department how it is handling these requests before you count on skipping a reroof permit.

Revised Section 105.3.4.1 gives local governments five business days to approve, approve with conditions or deny a complete application for a roofing permit, among other trades, on an existing single-family home when the work is valued under $15,000 and the applicant uses the local plans reviewer. A new Section 105.4.2 says a single-family permit expires one year after it’s issued or when the next edition of the code takes effect, whichever is later, though local governments can extend it.

## Already in the 9th Edition

The commission’s [summary of significant changes](https://www.floridabuilding.org/fbc/Committees/product%5Fapproval/2026%5FChanges/2026%5FFBC%5FSignificant%5FChanges.pdf?ref=ridgereport.news) lists the bigger roofing items that Supplement 1 builds on:

- **Hip and ridge shingles** (Section 1507.2.7.2) must be tested and classified to UL 2375 modified to a 110 mph wind speed, with packaging labeled to show it. The prescriptive alternative is two 1-inch spots of roof cement meeting ASTM D3019 or ASTM D4586, or another adhesive the manufacturer specifies, on each side of the hip or ridge near the leading edge, plus fastening to the manufacturer’s instructions.
- **Metal hip and ridge covers** (Section 1504.3.1.1) must be tested for uplift resistance under ANSI/MCA FTS-1.
- **Saltwater corrosion** (Section 1711): fasteners and connectors within 3,000 feet of a saltwater coastline must meet stainless, enhanced-galvanized or galvanized requirements based on distance from the shoreline and how exposed they are, with a tighter tier at 300 feet or less.

Miami-Dade has warned that the 9th Edition’s HVHZ changes will affect some current Notices of Acceptance for roofing underlayments and the testing and prescriptive attachment requirements for hip and ridge shingles. It has also put manufacturers on notice that systems approved over lightweight concrete on steel decks based only on 2-by-2-foot uplift tests must be updated.

## What to do before Dec. 31

Ask your distributor which hip and ridge products will carry the 110 mph UL 2375 label, and whether the underlayments and HVHZ systems you specify have updated approvals. Coastal crews should sort fasteners and connectors by exposure now. Estimators should get to know the $7,500 exemption and the five-day permit clock, both of which can change how small repairs get scheduled.

Tougher wind standards for roofs have been a running theme this year. Our coverage of [FORTIFIED’s new 15-year limit on asphalt shingle roofs](https://www.ridgereport.news/fortified-15-year-limit-asphalt-shingle-roofs-ibhs-2026/) covers the insurance-program side of that push. The commission’s next meeting is Dec. 8, according to its October agenda.
