CertainTeed, Valley Forge, Pa., introduces Centennial Slate™, the first in a new generation of asphalt roofing shingles that replicates the true look of blended slate. The product is made possible by a patent-pending shingle cutting and granule blending manufacturing process, invented by CertainTeed. The new product utilizes the company's exclusive Super Shangle® construction with two full-size 18- by 36-inch base shingles, resulting in four layers of shingle protection and 8-inch exposure when applied. Centennial Slate is available in six colors including Black Granite, Country Slate, Fieldstone, New England Slate, Plymouth Rock and Smokey Quartz. At 355 pounds per square, the product carries a lifetime, limited warranty, including coverage against winds of up to 110 miles per hour, and 10-year SureStart protection, which offers full replacement coverage in the unlikely event a manufacturing defect occurs in the early years following product application. Centennial Slate is algae-resistant, features a Class A fire rating and is certified by Underwriters Laboratories to meet ASTM D3462.
