Top 4 Roofing Materials for Wind-Disaster Prone Areas
The roof is one of the most robust aspects of any building structure, and often more susceptible to damage due to natural agents, such as hurricanes, tornados, and high-velocity winds. Although you cannot stave off natural calamities, despite adopting preventive measures, you can always strive to keep the damage to a bare minimum. Making informed roof material choices helps you achieve this goal. Continuing the discussion, we list the top four roofing materials that are suitable for residential properties in wind-disaster prone areas.
1. Asphalt Shingles
Asphalt shingles are one of the most affordable, yet sturdy roofing material choices for properties in high wind areas. During manufacture, asphalt shingles are subjected to comprehensive fan-wind tunnel tests, to grade them according to wind-rating specifications. Roofing contractors often install class-D shingles on properties that have to withstand wind speeds up to 90 mph, class-G shingles for areas with wind speeds of approximately 120 mph, and class-H for wind velocities up to 150 mph. A word of advice: avoid installing high-wind rated shingles over old shingles, and on flat roofs .
Slate roofs are water resistant and three times more durable than asphalt shingles. Slate is in the category of metamorphic rocks that are formed under intense pressure and heat. It is, therefore, exceptionally hard and fireproof. Slate’s structure cannot be compromised by flapping or bending due from high wind velocities. They are one of the favorite roofing material for multifamily property owners and managers in wind-disaster prone areas. Experienced roofing contractors can ensure maximum stabilization and resistance of slate roofs by incorporating adequate sloping, 4-inch headlap, and solid-wood roof sheathing.
3. Concrete Roof Tiles
Concrete tiles are designed so that they have a high air permeability rating to mitigate wind stress, and offer improved resistance to fire and hail. Tests have shown that concrete tiles are able to sustain wind velocities of 125 mph and even more. These roof tiles also have high UV reflectivity, making them an energy efficient roofing material. Residential properties in areas that have high wind speeds can incorporate concrete tiles into their roofing system, with a foam adhesive for increased wind resistance.
Metal roofs are a lightweight roofing solution, and exceptionally resistant to high velocity winds. There are several metallic roof materials available on the market that can be incorporated into a variety of roof designs. Popular materials include Galvanized steel (hot-dip zinc galvanized G90 steel), Galvalume steel ( zinc and aluminum coated steel), stone-coated steel, zinc, copper, terne, and stainless steel. Metal roofs can withstand wind velocities of more than 150 mph. They also have long lifespans, often extending up to 40 years or more.
Property owners have the responsibility to make informed decisions about the building’s structure and materials to be used. Their choices help determine the ability of the building to withstand the vagaries of nature. Commercial roofing and renovation contractors can help incorporate preventive measures in the structure of your property. They help in the assessment of the extent of damage, reconstruction of the building, claiming insurance support, and mitigating any recurrences.
