Strong winds can cause severe damage to your roofing, especially if your roofing system has certain qualities that make it vulnerable to wind damage. Keep reading to learn more about the factors that increase your roof’s susceptibility to getting damaged by wind.
If your roof wasn’t properly installed, it wouldn’t be durable enough to withstand strong winds. That said, using the correct nails is crucial to proper roof installation. Your roofer should use the right nailhead size and observe manufacturer prescribed nailing patterns when installing the shingles. Large-head roofing nails that are long enough to protrude through sheathing will best secure your roof against the wind.
Roof performance worsens as the roof ages because it gradually loses its protective granules and becomes brittle over time. Adhesive sections can begin to lose adherence over time as well, weakening the mechanical connection between shingle layers. Make sure your roof is regularly inspected and maintained so you’ll know when you need to replace your roof.
Shingles are classified based on their wind resistance. Some shingles are heavier mat than others which will increase wind resistance. Additionally, shingles have various types of adhesives that activate with sunlight and seal layers of shingles. Many of these adhesives are proprietary so differences may exist between manufacturers. Greater pliability will provide greater long term protection and seal. Generally, asphalt shingles on the market have a wind resistance classification as follows — ASTM D3161 Class F and ASTM D7158 Class H.
Roofs with large overhangs build air pressure underneath, effectively decreasing their wind resistance. This is why high-pitched gable roofs with wide overhangs generally have lower wind resistance than four-sided hip roofs.
If your area is prone to high winds, your roof should be designed and built to withstand that kind of weather. Local roofers would know the ideal roofing system for your area, so you should consult them during new roof construction or roof replacement.
