Florida has some of the strictest building codes in the nation, particularly for roofing. Understanding these requirements helps you make informed decisions about your roof and ensures your project meets legal standards.
Why Florida Has Strict Roofing Codes
After Hurricane Andrew devastated South Florida in 1992, exposing serious construction deficiencies, Florida overhauled its building codes. The result is the Florida Building Code (FBC)—one of the most comprehensive in the country.
Wind Resistance Requirements
Wind rating requirements vary by location:
Standard Zone (Most of Florida)
- Basic wind speed: 110-130 mph
- All roofing materials must be rated for this wind speed
- Proper nailing patterns required
High-Velocity Hurricane Zone (HVHZ)
Miami-Dade and Broward counties have additional requirements:
- Wind speed: 170+ mph
- Products must have Miami-Dade NOA (Notice of Acceptance)
- Enhanced installation requirements
- More rigorous inspections
Permit Requirements
Almost all roofing work in Florida requires permits:
What Requires a Permit
- Complete roof replacement
- Partial re-roofing (over certain size)
- Structural repairs
- Adding roof penetrations (skylights, vents)
Permit Process
- Contractor submits application with project details
- Building department reviews and approves
- Work proceeds with required inspections
- Final inspection and permit closure
Important: Work without permits can result in fines, required removal, and problems selling your home. Always verify your contractor pulls proper permits.

Inspection Requirements
Typical inspection points include:
- Deck inspection: After tear-off, before underlayment

- Final inspection: After complete installation
