CertainTeed Corp. expands shingle availability

CertainTeed Corp., Malvern, Pa., has expanded the availability of its NorthGate™ SBS polymer-modified bitumen shingle because of increased demand after the product's limited release in 2015.

NorthGate shingles are designed to endure harsh weather elements that threaten the longevity of residential roof systems. The shingles originally were made available in Alaska, British Columbia, Hawaii, Oregon and Washington. In the U.S., the shingles now are available in Illinois, Iowa, Kansas, Minnesota, Missouri, North Dakota, South Dakota, Wisconsin and select areas of Michigan and Nebraska. In Canada, the shingles now are available in Alberta, Manitoba, Saskatchewan and select areas of Ontario.
