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 more than 75 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. Our more than seven decades of success is the direct result of teamwork, enduring relationships with customers, suppliers and employees, and our company-wide commitment to continuous improvement, including the Six Sigma program, a business strategy and management philosophy designed to improve our processes and products. Vertical integration is also a key part of TAMKO’s success. We are a vertically integrated company, owning and operating several of our own raw materials plants. Maintaining greater control over the entire manufacturing process allows us to deliver consistent supply by reducing shortages and delivery times. Today, TAMKO operates manufacturing and warehouse facilities across the country in order to serve its customers with roofing and building products.
