CertainTeed’s History and Company Overview
CertainTeed was founded in 1904 as General Roofing Manufacturing Company in East St. Louis, Illinois. In 1917, General Roofing merged with Raglan Speer Roofing Company to form General Roofing Manufacturing and Supply Company. After a series of name changes and acquisitions, the company was renamed CertainTeed Corporation in 1967. The name “CertainTeed” was chosen to highlight the company’s commitment to quality and integrity.
Today, CertainTeed is a subsidiary of Saint-Gobain, a multinational corporation based in France. Saint-Gobain acquired CertainTeed in 2005. Together, Saint-Gobain and CertainTeed employ over 5,000 people across North America.
