Also available are MiraVista Shake shingles, which combine the textured look of natural wood with the durable strength of fiberglass composite technology. Available in three colors – Aspen, Walnut and Cedar – the simulated shake shingles are made of slate and clay reinforced with fiberglass and bonded with resin. They are molded from natural wood grains, and the color is consistent throughout the shake to prevent flaking or peeling during shipping or installation. The shakes are lightweight and they are immune to moisture. They come with a 50-year limited, one-time transferable warranty and have earned the highest rating for protection against fire – Class A.
