FAQs
Why is metal roofing a smart choice for homes and businesses in windy Townsend?
Metal panels interlock on all four sides and are screwed directly to the roof deck or structural purlins, creating a continuous, rigid surface that resists uplift. In coastal Townsend, where winter nor’easters and summer thunder squalls routinely generate 60-to-90 mph gusts, this strength means fewer blow-offs and leaks compared with shingle or tile roofs.
What wind speeds are your metal roofing systems rated to withstand?
Our standing-seam and screw-down metal roofs are tested in accordance with ASTM E1592 and UL 580/UL 1897. Depending on the profile and fastening pattern you choose, the panels carry ratings from 140 mph to 180 mph 3-second gust, which meets or exceeds the International Residential Code’s Wind Zone 1 requirements for Blount County and provides extra safety margin for extreme storms.
How do you install a metal roof so it resists wind uplift?
We start with a fully adhered synthetic underlayment that acts as an additional moisture and air barrier. Next, we use hurricane-rated fasteners spaced as close as 6" on center at eaves and ridges, double-clip the seams in high-pressure zones, and finish with continuous Z-closure and butyl sealant under every ridge cap. All edge metal is mechanically hemmed and screwed into blocking to prevent peeling during high winds.
Will a metal roof be noisy when high winds blow through Townsend?
Not when it’s properly installed. The panels sit on solid plywood or OSB sheathing separated by high-density underlayment and attic insulation, which dampen vibration. Most homeowners report that wind noise is actually lower than it was with their previous asphalt roof because there are no loose tabs flapping in the breeze.
How long can I expect a high-wind-rated metal roof to last compared with shingles?
A 24-gauge, Kynar-coated steel roof routinely lasts 50 – 70 years, while aluminum and zinc roofs can stretch past the century mark. In contrast, dimensional shingles in our wind zone are typically replaced every 15-20 years, often sooner after a major storm. Over the roof’s lifetime, metal’s durability translates into two to three fewer tear-offs and landfill loads.
Are there financial or energy benefits to choosing wind-resistant metal roofing?
Yes. Many insurers offer 15 %–30 % premium discounts for UL 2218 Class 4 impact- and high-wind-rated roofs. The reflective coatings on our metal panels carry ENERGY STAR certification, cutting summer cooling costs by up to 25 %. Add in the minimal maintenance and long service life, and most Townsend customers recoup their initial investment within 15–18 years.
