The Guardian shingle is a new generation of stone-coated steel roofing.
Gerard Roofing Technologies Inc., Brea, Calif., offers the Guardian shingle, a new generation of stone-coated steel roofing that is lightweight, durable and economic. Two-thirds lighter than heavyweight asphalt laminates, the shingle provides good looks, weatherproof performance and longer life. The price is competitive with upper-end asphalt composition products. Corrosion-resistant Zincalume steel panel offers structural advantages: It doesn’t warp, twist or split, and is noncombustible and highly resistant to hail.
