FAQs
What exactly are stone-coated metal roofing panels?
Stone-coated panels are galvanized or Galvalume® steel sheets that have been pressed into the shape of traditional shingles, shakes, or tiles and then coated with a layer of natural stone granules that are permanently bonded to the surface. The result is a roof that combines the strength and low weight of metal with the textured, matte look of conventional roofing materials.
How well do stone-coated panels handle Karns’ weather—summer heat, heavy rain, wind, and hail?
The steel core easily withstands wind speeds of 120–140 mph and carries Class 4 impact resistance—the highest rating for hail protection. The stone finish is UV-stable, so even under long, hot East Tennessee summers it won’t fade or crack. Interlocking tongues on all four sides keep wind-driven rain from getting under the panels, and the metal’s quick-dry surface resists mold and algae growth common in the humid months.
Will a stone-coated metal roof be noisy during our frequent rainstorms?
No. The stone granules dampen sound, and the panels are installed over battens and an underlayment that create an air space between the metal and the deck. Independent tests show rain noise levels only 2–3 dB higher than an asphalt shingle roof—well below what most homeowners can perceive indoors.
How long does a stone-coated roof last, and what kind of warranty is available?
Life expectancy is 50 years or more, roughly double that of high-end asphalt shingles. Most manufacturers offer a non-prorated 50-year transferable warranty that covers both the metal substrate and the stone coating against corrosion, chipping, and manufacturing defects. Our Karns installation crews are factory-certified, so the full material and 15- to 25-year workmanship warranties remain intact.
Is my existing roof structure strong enough, and can the panels be installed over old shingles?
Stone-coated panels weigh only 1.3–1.5 lbs / sq ft—about one-seventh the weight of concrete tile and half that of architectural shingles. Nearly every home in Karns built to standard code can support the load without reinforcement. In many cases we can install the new roof over one layer of shingles, eliminating tear-off mess and landfill fees, provided the deck is sound and local code allows it.
What does a stone-coated metal roof cost in Karns, and is it worth the investment?
Installed pricing generally ranges from $8–$12 per square foot, depending on profile, color, roof complexity, and any tear-off required. Up-front costs are higher than asphalt but lower than standing-seam metal or clay tile. Over its lifetime, a stone-coated roof recovers value through energy savings (up to 30 % lower cooling costs), reduced maintenance, insurance discounts for Class 4 impact rating, and an expected service life of 50 years or more—often doubling the life-cycle value compared with a standard shingle roof.
