Gerard Roofing Technologies has introduced a series of new steel-based roof systems. Its second-generation shingle, Granite Ridge, is a architectural roof shingle designed to compete with high-end asphalt composition products. The shingle sets new standards on warranties for life span (50 years), hail (2.5 inches) and wind (120 mph). Like its sibling, Guardian Shingle, the new product is stone-coated steel and offers easy, battenless installation. Granite Ridge presents a triple-coated finish with black shadow lines and is available in four colors.
