High winds can be a problem almost everywhere in North America. You want your roof to stay put. If the wind lifts them up, water can sneak in underneath potentially causing a leaky roof. Innovations in asphalt shingle manufacturing mean it’s a better product today than it was years ago.
Many shingle manufacturers have engineered all their shingles to meet the most stringent wind resistance tests in the industry. All meet the requirements for ASTM D7158 Class H and ASTM D3161 Class F wind ratings. That’s a lot of information just to say they have the ability to withstand 110-130 mph winds when they are installed according to the manufacturer’s guidelines.
Some of the top manufacturers offer high-wind limited warranties on even higher wind speed shingles. Have HEP INC. check your manufacturer’s guidelines and warranties if you believe that high winds are a large concern where you live in East Tennessee.
