| LAS VEGAS -- (BUSINESS WIRE) CertainTeed Corporation is introducing Centennial Slate™, the first in a new generation of asphalt roofing shingles that replicates the true look of blended slate. The new shingle made its debut this week at the Western States Roofing Contractors Association Annual Convention in Las Vegas. Centennial Slate is made possible by a sophisticated new patent-pending shingle cutting and granule blending manufacturing process, invented by CertainTeed, that creates an appearance on the roof that has never been achieved before with an asphalt roofing product. Centennial Slate utilizes CertainTeed's exclusive Super Shangle® construction with two full-size 18" x 36" base shingles, resulting in four layers of shingle protection and eight-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. "Never before has an asphalt shingle manufacturer been able to simulate blended slate with such accuracy and color intensity. Centennial Slate is a true technical achievement," says Husnu Kalkanoglu, Director of Research and Development for CertainTeed's Exterior Products Group. "It's a beautifully crafted shingle that offers contractors and homeowners an alternative to high cost, traditional blended slate." At 355 pounds per square, Centennial Slate 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, the roofing industry's tough shingle performance standard required by many of today's building codes.
