FAQs
Why is metal roofing a good choice for East Tennessee’s variable weather?
Knoxville experiences intense sun, heavy rain, high humidity, strong wind gusts during thunderstorms, and occasional snow or ice. Metal roofing is engineered to perform across this entire spectrum. Its interlocking panels resist wind uplift, the steel or aluminum won’t warp or rot in humidity, factory-applied paint systems are UV-stable for decades, and the slick surface sheds snow and ice quickly to prevent ice dams in the higher elevations around the city.
How long will a metal roof last in Knoxville compared to an asphalt-shingle roof?
A quality metal roof (24–26-gauge steel or .032 aluminum with a Kynar 500®/PVDF coating) routinely lasts 40–70 years. Standard three-tab asphalt shingles typically last 15–20 years in our region, and even premium architectural shingles average 25–30 years. Metal roofing’s longer lifespan means fewer tear-offs, lower life-cycle cost, and less material entering East Tennessee landfills.
Can a metal roof handle the high winds, hail, and heavy rain that hit Knoxville during severe storms?
Yes. Most residential standing-seam and metal-shingle products are tested to UL 580 or ASTM E1592 and carry wind-uplift ratings of 120–150 mph—well above the 90 mph design wind speed for Knox County. Many systems also hold a UL 2218 Class 4 impact rating, the highest available for hail resistance. Properly installed underlayment and concealed fasteners create a water-tight barrier, so wind-driven rain cannot penetrate the roof deck.
Will a metal roof make my home hotter in summer, or can it lower my energy bills?
Modern metal panels use high-performance, solar-reflective pigments that bounce a significant portion of the sun’s infrared heat back into the atmosphere. ENERGY STAR®-listed colors can reduce roof surface temperatures by 50 °F or more, lowering attic heat gain and cutting summer cooling costs by 10–25 %. In winter, the roof works with adequate attic insulation to retain interior heat, so overall year-round energy efficiency improves.
Is a metal roof noisy during rain or hail, and how can sound be minimized?
When installed over open framing, metal can sound louder, but most residential installations in Knoxville are placed over solid roof decking with underlayment and existing attic insulation. This assembly dampens vibration, making rain noise comparable to—or even quieter than—an asphalt-shingle roof. For additional sound control, high-density foam backer boards or acoustic underlayments can be added at a modest cost.
What routine maintenance does a metal roof require in East Tennessee?
Metal roofing is low-maintenance, but it isn’t completely maintenance-free. Once or twice a year, remove leaves, branches, and pine needles from valleys and gutters to prevent moisture buildup. After severe storms, visually check for displaced ridge caps or flashing, and tighten or replace any exposed fasteners if your system uses them. Wash pollen or mildew from shaded areas with a garden hose and mild detergent. Schedule a professional inspection every 3–5 years to ensure sealant lines and penetrations (vents, skylights, chimneys) remain watertight.
