Since 1944, the TAMKO story has been one of innovation, quality and long-standing customer relationships. Though a lot has changed since we introduced our first shingle over 70 years ago in Joplin, Missouri, one thing remains the same: our commitment to constantly moving the industry forward with a wide variety of building products. Today, TAMKO remains headquartered in Joplin—the very place it first began—and operates additional manufacturing facilities and warehouse facilities across the country in order to serve its customers with roofing and building products.

MFM Building Products, founded in 1961 by Robert E. Simpson, offers the construction industry more than 57 years of knowledge and expertise in the manufacture of waterproofing and weather barrier products. From humble beginnings, this family-owned manufacturing company has continued to grow and foster new product development, improved product performance, and help reduce overall costs with a value-based philosophy.
