If more than 25% of the roof is repaired or replaced within a 12-month period, the entire roof may need to be brought up to the latest Florida Building Code standards. This rule aims to enhance structural safety, particularly in hurricane-prone areas.

Why Storm-Resistant Roofing Is Vital in Florida

Key Florida Building Codes for Roofing
Florida’s building codes set high standards to safeguard homes in hurricane-prone areas. Miami-Dade and Boward County, in particular, has stringent regulations that any roofing material must meet to be approved for use (PDF). For a roofing product to receive the coveted “Notice of Acceptance” (NOA) in Miami-Dade County, it must undergo rigorous testing for wind uplift, water resistance, and impact resistance.
Living in the hurricane-prone areas like coastal Florida, Georgia, Carolinas, and Gulf states like Texas and Louisiana, means your roof needs to withstand extreme weather—high winds, heavy rain, and flying debris. Choosing the right hurricane-grade roofing system is critical for safeguarding your home and family during hurricane season.
Let’s explore the most durable roofing systems, focusing on wind resistance, durability, and cost, so you can make an informed decision.
Why Hurricane-Grade Roofing Matters
Hurricanes can produce winds of over 150 mph, which can easily tear off a poorly installed or low-quality roof. A hurricane-resistant roof provides wind resistance, waterproofing, and impact protection, ensuring your home can withstand the elements and minimize damage.

Metal roofing is one of the most wind-resistant roofing systems available, with interlocking panels and shingles that offer superior protection against wind uplift. Not only are they lightweight and durable, but they also reflect heat, reducing home energy costs.
Types of Metal Roofing:
Standing Seam: Vertical panels interlock to form a strong barrier against wind and water.
Stone-Coated Steel Roofing Shingles and Tiles: These mimic the appearance of traditional materials like clay or slate, while offering the durability and wind resistance of steel. The stone coating adds extra protection against corrosion and provides an aesthetic appeal.
