Lighter than asphalt yet five times tougher, this is metal roofing re-imagined for curb appeal, energy savings, and decades of worry-free living.
FAQs
What exactly is a stone-coated steel roof and how is it different from a traditional metal roof?
Stone-coated steel roofing panels are formed from corrosion-resistant galvanized or Galvalume® steel and then coated with an acrylic adhesive and ceramic stone granules. The stone finish gives the panels the dimensional look of shingles, shakes, or tiles while the underlying steel provides the strength of metal. Compared with bare standing-seam metal, stone-coated panels are quieter in the rain, offer a wider range of architectural styles, and hide minor oil-canning or fastener lines that can be visible on smooth metal surfaces.
How well does stone-coated steel roofing stand up to Farragut’s weather, including hail, high winds, and humidity?
Stone-coated steel is engineered to resist wind speeds of 120–130 mph and has Class 4 impact resistance—the highest rating for hail protection. The panels interlock on all four sides and are mechanically fastened to the deck, so they resist wind uplift far better than asphalt shingles. The baked-on base coat and stone chips are UV-stable and will not fade or peel under Tennessee’s intense summer sun, while the underlying zinc-aluminum alloy resists rust in our humid climate. Many homeowners in Knox County also report lower storm-related insurance claims because the roof simply doesn’t crack, curl, or blow off.
Will a stone-coated steel roof be noisy during rain or thunderstorms?
No. The stone granules, acrylic base coat, and the vented air space between the panel and roof deck all act as sound dampeners. Independent lab tests show that rain noise under stone-coated steel is comparable to—or even quieter than—architectural shingles. If additional sound reduction is desired, installing the panels over a high-density synthetic underlayment or adding attic insulation further lowers interior noise levels.
How long does installation take and what is the expected lifespan of the system?
A typical 3,000-square-foot Farragut home can be reroofed in three to five days, depending on roof complexity and weather. The lightweight panels (1.4–1.5 lb/ft²) often allow installation over a single layer of existing shingles, which speeds up the project and reduces landfill waste. Service life routinely exceeds 50 years. Manufacturers back their products with non-prorated 50-year warranties covering material defects, 120-mile-per-hour wind, and hail penetration. Because the panels will not dry out, crack, or lose granules like asphalt, their real-world lifespan frequently outlasts the original warranty.
Can a stone-coated steel roof help lower my energy bills?
Yes. The natural airspace created by the battens or elevated fasteners under the panels forms a thermal break, reducing heat transfer into the attic. Many profiles also use infrared-reflective stone chips that bounce a portion of the sun’s energy back into the atmosphere. Together, these features can lower attic temperatures by 30 °F or more in summer, translating into measurable savings on air-conditioning. Homeowners who upgrade from dark three-tab shingles in Farragut typically see 10–15 % reductions in cooling costs.
What maintenance, warranties, and potential insurance benefits should I know about?
Routine upkeep involves little more than keeping gutters clear and trimming overhanging branches. The stone finish hides dirt and minor debris, so power-washing is rarely needed. Most manufacturers offer a transferable 50-year limited lifetime warranty against manufacturing defects, plus separate warranties for wind and hail. Because stone-coated steel is both Class A fire-rated and Class 4 impact-rated, many insurers active in Tennessee—such as State Farm and Farm Bureau—offer 5–35 % premium discounts; check with your agent for exact figures. Registering your roof with the manufacturer and filing the impact-resistant documentation with your carrier will lock in those savings.
