Company History


In 1904, George M. Brown, a young entrepreneur in East St. Louis, Illinois, started the General Roofing Manufacturing Company. A manufacturer of roofing products, it was the predecessor of today's CertainTeed. As General Roofing's reputation for quality and service grew, so did the company. In 1988, CertainTeed became a wholly owned subsidiary of Saint-Gobain. Renowned for its expertise in glass technology, Saint-Gobain is the world's largest building materials company.

Today, with the full support of Saint-Gobain, CertainTeed's financial and technological resources are stronger than ever. Saint-Gobain Corporation, based in Malvern, Pennsylvania, is the holding company for the U.S. and Canadian based businesses of Saint-Gobain. In addition to CertainTeed, Saint-Gobain businesses in North America include:

• Saint-Gobain Abrasives
• Saint-Gobain Ceramic Materials
• Saint-Gobain Containers
