Class H high performance asphalt shingles can withstand wind speeds up to 150 mph, making them a viable option for storm-prone regions. For added security, hurricane-grade asphalt shingles are installed with six nails per shingle instead of the standard four, maximizing their wind resistance. It’s also critical to ensure the nails are driven flush without breaking the shingle to avoid weakening it against wind uplift.
Most high-performance shingles are classified as ASTM D3161 Class F and ASTM D7158 Class H, meaning they can resist wind speeds up to 150 mph. Always ensure that the shingles meet your local building code requirements and follow the manufacturer’s installation guidelines to maintain wind protection under warranty.
Note that currently there are NO Miami Dade County approvals for asphalt shingles, with the exception of ridge cap shingles from select manufacturers.

Reinforcing Your Roofing System for Optimal Storm Resilience
In Florida, material quality and installation practices are equally important. Roofing contractors must ensure all elements, from underlayments to fastening techniques, are compliant with Florida’s storm protection requirements. Here are some essential reinforcement techniques for a storm-ready roofing system:
1. Roof Decking
- The roof deck acts as the primary structural base, and 5/8-inch plywood or OSB is generally recommended for Florida homes. Ensuring strong, continuous decking provides a stable foundation that withstands the region’s extreme wind pressures.
2. Roof Frame Reinforcement
- In hurricane-prone areas, roof framing should include hurricane straps or ties that connect the roof structure to the walls, reducing the risk of roof uplift. Reinforcing trusses and beams with approved strapping systems keeps the roof more securely attached to the home, significantly lowering the chance of structural failure during high winds.
3. Underlayments
- High-quality, self-adhering and/or waterproof membranes are recommended, especially in Miami-Dade County where two layers of underlayments are required. These underlayments act as an additional moisture barrier, preventing water intrusion during heavy rain, and they’re also essential for managing wind uplift pressures.
4. Fasteners and Nailing Patterns
- Using corrosion-resistant fasteners, such as stainless-steel or zinc-coated nails, is critical in Florida’s humid, coastal climate. Proper nailing techniques, including the use of six nails per shingle, are a requirement in high velocity hurricane zones and provide greater stability and wind resistance. Fasteners should be driven flush with the surface without puncturing the roofing material, ensuring the integrity of each shingle, tile, or panel.
5. Roof Edge Sealing
- Securing the edges of the roof is crucial to prevent wind from lifting roofing materials. A properly sealed roof edge creates a wind-resistant perimeter that reduces the chance of shingles or tiles being dislodged, even during powerful gusts.
Conclusion
Selecting the right roofing materials and reinforcing your roof according to Florida’s building codes can make a significant difference in your home’s protection during a storm. Miami-Dade’s rigorous standards, such as the NOA certification, ensure that only the most durable and storm-resistant materials are used in high-risk areas. Roofing options like metal, high-performance shingles, and Miami-Dade-approved composite tiles offer both functionality and style for Florida homes. Prioritizing roof frame reinforcement, hurricane-zone nailing patterns, and robust underlayments will further increase your roof’s resilience, giving you confidence and peace of mind through Florida’s most challenging weather.
