Planning a roofing project in Florida involves more than selecting roofing materials and hiring a roofing contractor. Due to the state’s vulnerability to hurricanes and high winds, Florida has some of the strictest building codes in the country. Whether you’re hiring a roofing contractor to repair, replace, or build a new roof, understanding the Florida Building Code (FBC) is essential.

These codes dictate everything from material standards to inspection requirements, and following them isn’t optional. It’s the difference between a safe, insurable roof and one that may not stand up to Florida’s harsh weather.

What Florida Roofing Codes Are and Why They Matter

Florida roofing codes are mandatory standards that regulate the design, installation, and maintenance of roofs. The primary purpose is safety, protecting homes and buildings against severe weather, particularly hurricanes. These codes also aim to reduce property damage, lower insurance losses, and ensure energy efficiency.

The Florida Building Commission, which updates the FBC every three years, is responsible for developing and maintaining these codes. Local governments enforce them through building departments and inspectors. Any roofing work that doesn’t comply can result in denied permits, failed inspections, and costly penalties. Following the code isn’t just smart—it’s legally required.

How Florida Roofing Codes Protect Against Hurricanes

Florida’s roofing systems are built with hurricanes in mind. They include rigorous wind resistance standards that prevent roof failure during storms. One key element is wind uplift resistance, which ensures roof coverings can handle extreme pressure differences caused by high-speed winds.

To apply these standards, Florida uses ASCE 7 wind maps, which divide the state into regions based on wind speeds. Roofs in High-Velocity Hurricane Zones (HVHZ), like Miami-Dade County, face the most demanding requirements. These include more secure fasteners, specific material approvals, and specialized construction practices, all designed to keep your entire roof intact during a storm.

At the same time, there are affordable roofing options for Florida homeowners that meet these codes while offering protection and value, allowing them to balance safety and budget.

Approved Roofing Materials and Performance Requirements

Not all roofing materials are created equal in Florida. The FBC requires materials to be tested and approved for performance under extreme weather. This includes underlayment, asphalt shingles, clay tile, fasteners, and adhesives, all of which must be listed in the Florida Product Approval System or carry a Miami-Dade Notice of Acceptance (NOA).

Energy efficiency is another requirement. Shingle roofs must meet standards for solar reflectance and thermal emittance, especially in new builds. Fire resistance and proper drainage are also regulated, and incompatible materials, such as certain metal roofs, are prohibited when installed in coastal areas.

Using the right, code-approved components is crucial for long-term performance and compliance. At Gustafson Roofing, we use only Florida-approved roofing materials that meet strict code requirements, so you get a roof that’s built to last, energy efficient, and ready for Florida weather.

Installation and Structural Requirements for Florida Roofs

Roof construction isn’t just about putting down shingles. Florida’s code outlines strict structural and fastening requirements. Roof decking must be attached using 8D ring-shank nails with specific spacing. Asphalt shingle and tile coverings must be secured with prescribed nailing patterns or adhesives, especially in HVHZ areas.

The Florida Building Code also requires a secondary water barrier—a self-adhering underlayment that offers added protection if the main covering is lost. These installation techniques reduce the risk of water intrusion and structural failure. If a roof isn’t installed exactly to code, it could be disqualified from passing inspection or withstanding a storm.

Differences Between Re-Roofing and New Roof Construction

Florida distinguishes clearly between new roof installations, re-roofing, and roof repairs. In re-roofing, the code allows a maximum of two layers. If your roof already has two, a complete tear-off is required before installing a new one. You’ll also need to verify the condition of the deck and flashing.

New construction has stricter energy and structural requirements, while repairs must still comply with the latest code for affected areas. Regardless of project type, permits and documentation are required. Attempting to bypass the rules, such as reusing damaged components, can lead to inspection failures and insurance issues.

Inspection Requirements for Florida Roofing Projects

Inspections are a key part of Florida’s roofing process. Most projects require at least two: a dry-in inspection and a final inspection. During the dry-in inspection, the underlayment, fasteners, and roof decking attachments are reviewed before the roof covering goes on. The final inspection ensures full code compliance upon completion of the job.

Local building officials or licensed roofing professionals carry out inspections. If a roof fails inspection, the contractors must fix the problem and schedule a recheck. Passing these inspections isn’t optional; it’s a legal requirement for completing permitted roofing work.

Gustafson Roofing makes inspections easier. We handle every step of the inspection process to ensure your roof meets Florida code, passes smoothly, and stays on schedule—no surprises, just solid, compliant workmanship.

Recent Code Changes and Common Roofing Mistakes

The Florida Building Code evolves regularly. Recent updates have increased the requirements for corrosion-resistant fasteners, clarified the use of secondary barriers, and expanded energy efficiency standards. These updates reflect lessons learned from recent storms and advances in roofing materials.

Common mistakes include using unapproved roofing materials, improper fastener placement, or skipping secondary water barriers. Failing to follow the updated code can result in denied permits, failed inspections, and even insurance claim rejections. Working with roofing contractors who are familiar with the latest codes is essential to avoid these pitfalls.

How Local Rules Can Differ From State Roofing Codes

While the Florida building codes provide a statewide standard, local jurisdictions can enforce stricter requirements. Coastal areas, for example, often add additional wind resistance rules or limit certain roofing materials due to salt corrosion or flood exposure.

Before starting your project, check with your local building department to ensure compliance with any applicable regulations. They’ll inform you of zoning rules, permit needs, and inspection steps unique to your area. Never assume state code alone is enough; local codes may require additional compliance.

Where to Find Reliable Updates on Roofing Code Changes

To stay informed, use resources like the Florida Building Commission’s website, the Florida Product Approval System, and your local building department. These offer access to updated codes, approved materials, and permit guidance.

Experienced contractors stay current through continuing education, trade organizations, and code certification programs. Don’t hesitate to ask how your roofing contractor keeps up with the law. Being informed helps ensure your project stays compliant from start to finish.
