Stone-coated Steel | Metal Roofing | Roofing | Guild
Imagine the timeless beauty of classic clay tiles or hand-cut shakes, now fortified with the rugged durability of steel. HEP’s stone-coated panels marry elegant curb appeal with next-level protection, resisting wind, hail, fire, and even the relentless Tennessee sun. Each interlocking panel is stone-granule finished for rich color that won’t fade, while the underlying 26-gauge Galvalume® core shrugs off corrosion and keeps your home dry and secure for decades.
Because our stone-coated system is up to three times lighter than traditional roofs, it installs quickly over most existing decks, easing structural stress and saving disposal costs. It also reflects radiant heat, helping HVAC systems run more efficiently and trimming energy bills—a win for both comfort and the environment. When you want a roof that looks like fine architectural detail but performs like advanced engineering, choose HEP’s metal roofing solution and enjoy strength you can see and peace of mind you can feel.
FAQs
What is stone-coated steel roofing and how is it different from traditional metal or asphalt shingles?
Stone-coated steel roofing panels are made from corrosion-resistant galvanized or galvalume steel that is formed into profiles (shake, tile, shingle, etc.) and then coated with an acrylic layer and ceramic stone granules. This fusion delivers the lightweight strength of metal with the textured, attractive appearance of conventional roofing materials. Unlike bare metal panels, the stone granules reduce glare and noise, and unlike asphalt shingles they will not crack, curl, or lose granules prematurely.
How long can I expect a stone-coated steel roof to last in Guild’s climate?
With proper installation and minimal upkeep, a stone-coated steel roof routinely lasts 50 years or more. The steel core resists rust and impact, while the baked-on acrylic and stone finish shields the panels from UV degradation, moss growth, and color fade. Even in Guild’s mix of hot summers, heavy rains, and occasional hail, the system’s Class 4 impact rating and 120-mph wind warranty keep it performing decades beyond the 15–25-year life of typical asphalt shingles.
Is stone-coated steel roofing noisy when it rains or hails?
No. The embossed profile, stone granule surface, and solid sheathing or battens beneath the panels all help absorb sound. Independent tests show interior noise levels comparable to or quieter than those under asphalt shingles. Adding a quality underlayment or attic insulation further deadens rain or hail impact sounds, so most homeowners notice no difference after the upgrade.
How heavy is stone-coated steel compared with other roofing materials, and will my structure need reinforcement?
At 1.3–1.5 lbs per square foot, stone-coated steel is one of the lightest premium roofing options—about one-eighth the weight of concrete or clay tile and roughly half the weight of architectural asphalt shingles. Because of its light load, most existing homes in Guild do not require structural reinforcement. In many reroof projects the panels can even be installed over a single layer of old shingles, reducing tear-off waste and installation time.
What maintenance is required to keep a stone-coated steel roof performing well?
Maintenance is minimal. Keep gutters clear so water can drain freely, trim overhanging branches that might abrade the surface, and visually inspect flashings and fasteners every few years. If airborne debris or algae accumulates, it can be safely washed off with a low-pressure garden hose and mild detergent; power-washing is not recommended. The non-porous stone finish discourages moss and prevents the color loss common to asphalt granules.
What kind of warranty and overall value can I expect from a stone-coated steel roof installed by Guild Roofing?
Guild Roofing provides a transferable lifetime material warranty that covers manufacturer defects, 120-mph wind damage, and Class 4 hail impact, plus a 20- to 25-year workmanship warranty backed by our certified installation crew. Although the initial investment is higher than asphalt, the roof’s long life, energy efficiency (up to 30 % cooling savings from the reflective base coat), lower insurance premiums, and near-zero replacement costs make stone-coated steel the most cost-effective choice over the life of your home.
