FAQs
How well does a metal roof stand up to Cosby’s frequent high-wind events?
Properly engineered metal roofing systems are tested and rated for wind speeds of 120–150 mph—well above the 110 mph basic wind speed shown on the 2021 Tennessee Adoption of the I-Codes. When the panels are installed with the correct spacing, clip system, and edge details, uplift resistance is several times higher than that of architectural shingles, making metal the safest choice for Cosby’s mountain gusts.
What type of metal roofing profile should I choose for maximum wind resistance?
For homes and cabins in Cosby we recommend a standing-seam panel with hidden clips and 24-ga steel. The continuous seams lock together vertically, leaving no exposed fasteners for the wind to grab. If budget is tight, a 26-ga exposed-fastener “R-panel” can still meet 120 mph ratings when installed on 16-in. purlin spacing, but standing seam offers the best long-term protection.
Do local codes require any special fasteners or installation methods?
Yes. Sevier County follows the 2018 International Residential Code with local amendments that call for fasteners to be corrosion-resistant #10 or larger screws with neoprene washers, driven into framing (not just sheathing) at prescribed spacing. Eave and ridge trim must include butyl sealant tape, and panels along edges must have clip spacing reduced by one half. Our crews meet or exceed every one of these requirements.
Will a wind-rated metal roof lower my energy bills or insurance premiums?
Absolutely. The baked-on Kynar 500 finish reflects up to 35 % of solar heat, which the Oak Ridge National Laboratory estimates can cut summer cooling costs 10–15 %. Most insurers doing business in East Tennessee offer 5–15 % discounts for UL 2218 Class 4 impact- and wind-rated metal roofs because they rarely have to pay claims for wind damage.
How much more does a metal roof cost than traditional shingles in Cosby?
As of 2024, a high-wind rated standing-seam metal roof in Cosby averages $9–$12 per sq ft installed, while a premium architectural shingle roof runs $5–$7 per sq ft. The initial 30–50 % price difference is usually recouped within 15 years through lower maintenance, energy savings, and insurance discounts—plus metal lasts 50+ years versus 20 years for shingles.
What maintenance is required after a windstorm and what kind of warranty is included?
After any major wind event we advise a simple visual check for loose ridge cap or debris accumulation; no re-sealing is necessary under normal conditions. We include a 40-year manufacturer paint warranty, a 25-year corrosion warranty, and our own 10-year workmanship warranty that covers wind-related leaks up to 140 mph sustained speeds. If you ever see an issue, call us—inspections are free for the life of the roof.
