PlyGem’s new Engineered Cedar roof shingles are crafted to mimic the look of milled cedar shingles, and come with a gray hue similar to that of weathered wood. The shingles are made from the same polymer formulation as the company’s Engineered Slate roofing, with nearly 100% recycled resins. They can be cut and scored with a utility knife and fastened in place with roofing nails fired from a standard nail gun. Pricing should be on a par with premium asphalt shingles.
