GAF.GAF-Elk Timberline Prestique 40 HD Cool Color Series shingles are available in three shades that meet tax credit requirements. Without looking washed out or faded, the colors — cool weathered wood, cool barkwood, and cool antique slate — help slow down heat buildup for greater energy efficiency. Highly reflective granules in the shingles bounce back the sun’s rays and release absorbed heat to reduce roof temperatures and keep homes cooler. Using the cool barkwood and cool antique slate colors may also earn LEED points for a project. 973.628.3000. www.gaf.com.
