  • Granite Ridge Galvalume metal stone-coated shingles are a lightweight, tough and economical roofing backed by a lifetime warranty. This new-generation shingle is not only 67 percent lighter weight than asphalt laminates, but its raised seam joints also ensure enhanced protection against the elements.
  • Allmet Continental gives roofs the appearance of high-profile S-type concrete tiles. Yet it is lighter weight than standard cement- or clay-based tile.
  • Allmet Wood Shake melds the natural beauty of wood shake with the strength of metal roofing. This wood shake product won’t catch fire or blow off in high winds. Because many areas prohibit wood shake, stone-coated metal wood profiles are a good alternative.
  • Allmet Shadowline offers the aesthetics and dimension of natural slate and features four ENERGY STAR-rated colors among its 19 color blends.

Allmet is backed by a limited lifetime transferable warranty that covers up to 120-mph winds, 2.5-inch hailstones and fire.

Stone-coated metal roofing systems from Gerard, a Headwaters Roofing brand, are available in a broad array of colors—three of which are ENERGY STAR approved—and profiles, including shingle, shake and tile. Constructed of 26-gauge Galvalume steel panels, Gerard roofing systems include a Class A fire rating, a 2.5-inch hailstone warranty and a 120-mph wind warranty. Although Gerard stone-coated metal roofing systems can be installed direct to deck, the optimum energy-saving method is to install on top of a batten or counter-batten grid.
