Weighing one-third the weight of the real thing, the Slate Shake tile is manufactured with up to 10 percent recycled content and saves on framing material and transportation energy, the company says. The synthetic product will not crack like real slate, comes in a variety of colors, and offers a limited lifetime warranty.
