CertainTeed is a leading U.S. manufacturer of low slope and steep slope roofing products for commercial, industrial, institutional, and residential roofing and waterproofing applications.  CertainTeed has served the roofing industry for 100 years, establishing a solid reputation for quality, reliability, and technical innovation.

CertainTeed manufacturers the industry's most extensive line of asphalt shingles.  Pioneering the concept of multi-layered shingles, also known as architectural or designer shingles, the company has been an industry leader in color innovation with complex color blending technology and the introduction of bold designer shingle colors such as variegated reds, blues and greens.

When a roof can account for as much as 40% of the average home's exterior, many factors weigh into the choice of materials.  Some surfaces are more beautiful than others.  Some offer greater resilience or endurance.  Some are more affordable.  But the one roofing surface which offers all those attributes in balance is the asphalt shingle.

Now accounting for about 80% of the residential roof surfacing in the United States, asphalt shingles are measured against a variety of standards that evaluate fire and wind resistance, tear strength, and other key performance indicators.  For fiber glass shingles, ASTM D3462 is considered the most important.

This comprehensive standard covers tear strength, nail-pull resistance and pliability, among other shingle characteristics.

Over 20 CertainTeed fiber glass shingles are independently certified by Underwriters Laboratories to meet the tough ASTM D3462 standard.
