A Brief History
When George Brown founded the General Roofing Manufacturing Company in 1904, he could not have imagined the explosive growth this country would experience. The company’s name was changed in 1917 to Certain-Teed from its slogan “Quality made certain, Satisfaction Guaranteed.” The company continued to grow as the premier asphalt shingle manufacturer. In the 1960’s, the company acquired both a fiberglass insulation business and PVC pipe businesses which led to the introduction of solid vinyl siding. The addition of both Gypsum and Ceilings in 2007 rounded out the scope of building materials currently manufactured by CertainTeed.
