Thousands of contractors, architects and builders around the world rely on Koppers Coal Tar Built-Up Roofs (BUR) to protect their buildings from harsh environments. With proper maintenance, Koppers roofs last for decades. At the Pentagon a Coal Tar BUR kept the U.S. Department of Defense offices secure for 60 years, until a terrorist attack on Sept. 11, 2001. Koppers provides all the components needed to build a coal-tar roof, to meet varying specifications.
