FAQs
What does a 140-mph wind rating mean for my metal roof in Jonesborough?
A 140-mph rating indicates that the roofing system—panels, fasteners, and underlayment—has been laboratory-tested and certified to resist uplift pressures created by winds up to 140 miles per hour. In practical terms, your roof is engineered to stay intact during Category 3 hurricane-force gusts, which far exceed the strongest straight-line winds historically recorded in Jonesborough. This rating helps protect your home from shingle blow-offs, water intrusion, and structural damage during severe thunderstorms and high-wind events common to Northeast Tennessee.
How does metal roofing perform against hail, heavy rain, and other severe weather in our region?
High-grade steel panels with a 140-mph rating also carry Class 4 impact resistance—the highest available—so they can withstand large hail without cracking or perforation. The interlocking design sheds heavy rain quickly, minimizing leaks and standing water. Because metal is non-combustible, it also offers excellent fire protection from lightning strikes or stray embers. Together, these qualities make a metal roof one of the most durable, weather-resilient options for Jonesborough homes.
Are there local building codes or insurance benefits for installing a 140-mph metal roof in Jonesborough?
Washington County follows the 2018 International Residential Code, which requires specific uplift resistance for new roofs. Our 140-mph system exceeds those requirements, so permitting typically moves smoothly. Many insurers offer premium discounts—often 5 %–15 %—for roofs with high wind or impact ratings. We provide all certification paperwork, including ASTM and UL test reports, to help you secure any available credits from your carrier.
Will a metal roof rated for high winds be noisy during rain or storms?
Not when installed correctly. A modern metal roof sits over solid decking, a high-density synthetic underlayment, and optional foam backer board. These layers absorb sound, making indoor noise levels comparable to—or quieter than—those under asphalt shingles. Homeowners frequently report that rain on a properly insulated metal roof is a soft patter rather than a loud drum.
How is a 140-mph wind-rated metal roof installed differently from a standard roof?
We use thicker 26- or 24-gauge steel panels, double-lock seam or screwed-down profiles with engineered clip systems, and stainless or coated fasteners rated for uplift loads. Fastener spacing is reduced at eaves and ridges, and all perimeter trim is reinforced with butyl tape and sealant. Ridge caps and hip flashings are mechanically seamed for additional hold. These steps create a continuous, interlocked surface that resists wind getting under the panels and lifting them.
What maintenance and warranty coverage can I expect with your 140-mph metal roofing system?
Maintenance is minimal: keep gutters clear, remove large debris after storms, and schedule a visual inspection every few years. The finish carries a 40-to-50-year manufacturer’s warranty against fading, chalking, and corrosion, while the panel system has a lifetime limited warranty on wind damage up to 140 mph. Our workmanship warranty covers installation for 10 years, and both warranties are transferable if you sell your home, enhancing resale value.
