Roofing Materials for High-Wind Areas

Asphalt shingles stand up well to high winds and you can choose the strength you need to meet ASTM standards on wind resistance. The building codes in your region will shed light on the type of shingles that will withstand harsh weather conditions. You can also ask for recommendations from your homeowner’s insurance carrier as they may have restrictions on what types of roofing materials are not suitable for your region. A local roofing company, such as Premier Roofing, will be familiar with the climate, local building codes, and the type of shingles you will need to protect your home during storm season. Consulting with professionals will help you navigate the complexities of roof replacement after a major weather event and eliminate the guesswork (and stress) of trying to do it yourself.

During a high-wind weather event, your roof takes a beating. Not only are wind velocity and direction factors, but so are wind/barometric pressure and terrain. A common occurrence is uplift, where the wind can “lift” the corners of your roof, whereas negative suction pressure can “suck” shingles off. Fortunately, there are installation techniques to help prevent these types of destruction. Straps and fasteners can help secure your roof and shingles during a hurricane or tornado. For hurricane regions, it is advised to use galvanized stainless-steel fasteners to affix your roof to the structure of your house. In other areas prone to high winds, standard straps will suffice. Working with a local roofing company such as Premier Roofing can recommend the best fasteners to secure your roof during a major weather event.

Did you know that in many cases, the most extensive roof damage isn’t visible to the naked eye and occurs inside your home? Having your roof inspected regularly will reveal damage such as mildew and mold, pests, and rotting wood in your attic. A roofing inspector will also check shingles and flashing on top of the roof to look for discoloring, gaps, cracks, and holes. If you think that your roof may need replacing, but aren’t sure, have it inspected. Premier Roofing will conduct a free, no-obligation inspection of your roof and give you an honest assessment of its condition and whether a complete replacement or repair is recommended.

High winds are the number-one cause of shingles uplift. Whether it’s from a single weather event or repeated exposure, strong winds can cause asphalt shingles to “lift” or separate from the underlay, which invites water damage. Improper installation can also contribute to shingles uplift. There are special kinds of sealing and nails that can help prevent uplifting and this type of repair or installation is best left to professionals — it’s not a DIY project. Professional roofing companies such as Premier Roofing will know which types of materials and installation techniques can help protect your asphalt shingles from uplift.

ASTM stands for the American Society for Testing and Materials develops voluntary standards for many industries, including the roofing industry. ASTM has developed standards for wind resistance, specifically ASTM D7158, “Standard Test Method for Wind Resistance of Sealed Asphalt Shingles” (Uplift Force/Uplift Resistance Method.) D7158 classifies shingle products based on their uplift force resistance when tested at various wind speeds.

Class D resists uplift at wind speeds up to 90 mph

Class G resists uplift at wind speeds up to 120 mph

Class H resists uplift at wind speeds up to 150 mph

This is another instance where you would check with your homeowner’s insurance agent or local building codes to see if any D7158 classification is recommended or required for your area. In addition, a local roofing company, such as Premier Roofing, will have this information and know which manufacturers produce asphalt shingles that meet D7158 standards.
