Choosing the Best Roof for Hurricanes and High Winds
Florida is a state that is no stranger to hurricanes. Until Hurricane Andrew created devastating damage along the Florida coast in 1992, the state had over 400 building codes that didn’t adequately protect Florida structures. After this devastation, they adopted the Florida Building Code in 2002. This new statewide code required all new construction to be capable of withstanding hurricane-force winds.
The code also highlights high-velocity hurricane zones (HVHZ) requiring more serious protections, including a hurricane proof roof. There are two HVHS zones in the state: Broward and Miami-Dade Counties.
The roof is one of the most vital parts of your home, providing essential protection, especially during hurricane season. So, what type of roof is best for hurricanes?
5 Considerations for Hurricane Roofing
It isn’t all about the material when considering hurricane roofing in Florida. You also must consider your roof, as it helps determine the most suitable materials. More specifically, consider the:
1. Best Roof Shape for a Hurricane
Roofs come in a variety of shapes, and while the ideal shape would be hexagonal or octagonal, these aren’t common shapes. The general idea is to have a multi-paneled shape, which will help reduce wind loads or the pressure exerted onto the roof. This makes a hipped roof with four or more sloping sides the best shape for hurricane winds.
2. The Best Roof Pitch for High Winds
A roof’s pitch, or slope, is how steep the sides of the roof are. It is another important factor to consider When determining your roof’s hurricane resistance. The ideal roof pitch for high winds is 7:12 or less, which makes the roof more resistant to wind uplift, which could cause the roof to separate from the building.
3. Length of Roof Overhang
The best roof design for high winds would also reduce the amount of roof overhangs, minimizing the risk of wind uplift and other related damage. For the best protection, overhangs should be less than 20 inches.
4. Types of Straps and Fasteners
Florida takes hurricane preparedness very seriously. Since Hurricane Andrew in 1992, all new construction must have specialized hurricane fasteners. These are typically galvanized or stainless steel and help keep your roof connected to your home. They are connected by the walls or the home’s foundation.
5. Pressure Points
Pressure points are areas of the roof that are subject to higher wind pressures. These points include ridges, corners, and eaves, requiring extra attention when applying fasteners.
6 Hurricane Resistant Roof Options
There is no shortage of roofing options in Florida, with companies all providing a different selection. FL Speciality Roofing is one company offering a wide range of top brands across various materials. These options include:
1. Clay and Concrete
Clay and concrete tiles are extremely popular in Florida as they offer an upscale, Mediterranean feel. These tiles come in various colors and styles, including flat and barrel. They are incredibly durable and one of the best hurricane proof roof options. Tile roofing offers wind resistance up to 130 mph. The weight of clay and concrete tiles also helps to hold the tiles in place, adding to their wind resistance.
2. Slate
While clay and concrete tiles are more common, slate isn’t that far behind. A slate roof can withstand winds up to 110 mph, and while it is less than clay and concrete, the weight of slate roofing will help keep it in place. This helps minimize concerns about wind uplift. Slate roofing is also Class 4 impact-resistant and offers water resistance.
3. Wood Shakes and Shingles
Wood shakes and shingles aren’t something you may necessarily associate with Florida or hurricane-resistant roof materials, but you would be surprised. Wood shingles offer wind resistance up to 173 mph, while high-quality shakes can withstand winds up to 245 mph when properly installed. Cedar is naturally water resistant, and special treatments can provide additional protection.
4. Metal
Metal roofing started as a predominately commercial option but has become increasingly popular among homeowners. Metal roofing offers a more modern aesthetic and is also incredibly durable, making it a great option for hurricane roofing. These roofs can withstand winds up to 160 mph, making them one of the most wind-resistant roofing materials. Stone-coated metal roofing adds extra durability by giving the material added protection from impacts, up to a Class 4 impact rating. It is also a water-resistant material.
This durability also means they have a longer lifespan, lasting around 40 to 70 years when properly installed. Metal roofs come in a variety of styles, including standing seam, corrugated, shake, tile, and clay-look styles.
5. Asphalt
Asphalt shingles are one of the most common roofing materials due to their wide availability and affordability. That doesn’t mean they don’t have their benefits; like clay and concrete, they can withstand winds up to around 110 mph when new. They are also impact and water-resistant.
6. Composite
Composite or synthetic roofing is an option that is growing in popularity. This type of roofing is often made using recycled plastics that are compressed into tiles. They can resemble popular materials like cedar shakes, clay tiles, or slate roofing. These products offer an incredibly realistic appearance and are lightweight.
FL Speciality Roofing offers two top brands: Brava and DaVinci. Brava products’ wind resistance is dependent on the installation method: up to 188 MPH with nails and up to 211 MPH with high wind/screw installation. DaVinci offers an average wind rating of up to 110 MPH, but it is also HVHZ rated for Indy’s up to 180 MPH. Composite roofing provides essential protection, beauty, and value, and it is possibly the best roof for hurricane zones like Florida.
Making Sure Your Roof is Hurricane-Ready
Florida’s weather is unpredictable on a good day, and during hurricane season, things can be even more unpredictable. Ensuring you, your family, and your home are ready is crucial. The best way to prepare your home is to have a hurricane-resistant roof. The options listed above are some of the best overall, but what is best depends on your roof and budget. FL Specialty Roofing can help you find the best material for your home and install it in no time.
