CertainTeed Corporation has unveiled Symphony, a sophisticated new roofing shingle formed with the texture and contours of real quarried slate. Available in the Philadelphia, Baltimore and Washington, D.C., markets, this beautifully engineered polymer composite roofing product mimics the look and feel of traditional slate, yet lighter, more durable and costs a fraction of the price of slate. The new slate-style roofing products come in two blends: Colonial gray, a mixture of subtle gray, and Capitol blend, a combination of gray, plum and green. The lightweight material makes Symphony easy to install. It requires no special installation tools and can be fastened by hand nailing or nail gun, without cracking. Symphony also features a UV fade-resistant surface technology for superior color stability. It has a 50-year limited, transferable warranty. It is U.L. Class A fire resistant with an appropriate underlayment and U.L. 2218 Class 4 impact resistant. For more information, visitwww.certainteed.com.
