Metal Roofing

Metal roofing has become one of the fastest-growing segments of the residential roofing market, and for good reason. In East Tennessee’s climate — with its hot, humid summers, occasional ice storms, and severe thunderstorms — metal roofing offers performance advantages that asphalt shingles simply can’t match. A.T.C. Contractors installs a full range of metal roofing systems for both homes and commercial buildings throughout the Knoxville area.

Benefits of Metal Roofing in Tennessee

Exceptional Longevity

A properly installed metal roof lasts 40-70 years, compared to 20-30 years for asphalt shingles. Many metal roofs installed decades ago are still performing well today. This means you may only need one more roof for the rest of your time in your home.

Superior Storm Resistance

Metal roofing panels are rated for wind speeds of 110-140 mph or higher, depending on the system. They don’t have individual shingles that can lift or blow off, and standing seam panels interlock to create a continuous barrier against wind-driven rain. In hail-prone areas like East Tennessee, metal roofing with concealed fasteners resists denting better than exposed-fastener systems.

Energy Efficiency

Metal roofs reflect a significant portion of solar radiation, reducing cooling costs by 10-25% in Tennessee’s hot summers. Many metal roof coatings qualify for ENERGY STAR ratings. When combined with proper attic ventilation and insulation, a metal roof measurably lowers your energy bills year-round.

Low Maintenance

Metal roofs require virtually no maintenance beyond occasional visual inspection and gutter cleaning. There are no shingles to replace, no granules washing away, and no moss or algae growth to worry about. A periodic cleaning with a garden hose keeps the surface looking new.

Increased Home Value

Studies consistently show that metal roofing adds to a home’s resale value. Buyers recognize the low maintenance, longevity, and energy savings. According to industry data, homeowners recoup an average of 60-85% of metal roofing costs at resale.

Types of Metal Roofing We Install

Standing Seam Metal Roofing

Standing seam is the premium metal roofing option. Panels are joined by raised seams that interlock mechanically, with no exposed fasteners. This design eliminates the most common source of metal roof leaks — fastener holes — and provides a clean, modern appearance. Standing seam panels expand and contract freely with temperature changes, reducing stress on the system. Available in steel, aluminum, and copper.

Exposed Fastener Metal Panels

Also called screw-down panels, these are the most affordable metal roofing option. Panels overlap and are secured with self-tapping screws fitted with neoprene washers. They’re a practical choice for secondary structures, agricultural buildings, and budget-conscious residential projects. The fastener washers should be inspected every 10-15 years and replaced if they’ve degraded.

Metal Shingles and Shake

For homeowners who want the longevity of metal but the look of traditional shingles, cedar shake, or slate, metal shingles are an excellent option. These interlocking panels are stamped and coated to replicate the appearance of other roofing materials while delivering metal’s durability. They work well in neighborhoods with HOAs or historic districts where a traditional look is required.

Metal Roofing vs. Asphalt Shingles: Honest Comparison

We install both, so we’ll give you a straightforward comparison:

• Upfront cost: Metal roofing costs 2-3 times more than asphalt shingles for the initial installation.
• Lifetime cost: Over 50 years, metal roofing is often cheaper because you avoid 1-2 replacement cycles that asphalt would require.
• Durability: Metal wins decisively — it handles wind, hail, and fire far better than asphalt.
• Noise: A common concern. With proper underlayment and solid decking, a metal roof is no louder than asphalt during rain.
• Resale value: Metal adds more value, though asphalt is the expected standard in most Knoxville neighborhoods.
• Insurance: Some Tennessee insurers offer premium discounts for metal roofs due to their wind and fire resistance.

The right choice depends on your budget, how long you plan to stay in your home, and your aesthetic preferences. We’ll help you weigh the options honestly.

Commercial Metal Roofing

For commercial properties, metal roofing systems from manufacturers like Carlisle SynTec and Firestone provide the durability and weather resistance that flat and low-slope commercial roofs demand. We install TPO, EPDM, and metal panel systems for commercial buildings, warehouses, and retail properties across East Tennessee.
