RGM Products Inc., Fresno, Calif., introduces Chancellor, an SBS-modified asphalt super-heavyweight shingle with the look of wood and slate. Its patented one-piece construction guards against delamination, which can occur when using standard asphalt shingles. This hand-crafted design also ensures that water is diverted away from the roof deck. Also available is Chancellor AR with Scotchgard™ Algae Resistant Roofing System from 3M. When installed with additional roofing products manufactured by RGM, Chancellor is warranted for a lifetime. The shingle carries a Class III Impact rating, a Class A Fire rating, and exceeds the 110 mph. wind-driven rain and wind-uplift tests. A lifetime warranty is available when all requirements are met.
