Mission Statement

Quality Building Supply Company will provide its customers with many quality products to choose from to meet and exceed their needs and requirements. They will also provide them with exceptional service in their buying and delivery experience. QBS strives to go above and beyond their competitors in these areas, to retain their customer's business.
Our company has been in the business of wholesaling residential and commercial roofing, sheet metal products, vinyl siding, aluminum soffit and aluminum gutter supplies for over 60 years. We supply only the best materials from national vendors and manufacturers. Quality employs a staff of eighteen capable and courteous people whose purpose is to service our customers and help make their job easier. The turnover rate of our staff is one of the lowest in the industry, and as a result, most of our clients are greeted by name by our employees before they even come into the office. The owners are proud of the Quality tradition and our employees share that feeling.

The current ownership of Quality Building Supply is shared in partnership by Mark E. Exiner and Walter Piton, who have between them nearly sixty years of experience in the roofing and distribution industry. The company was founded in June 1951 by Samuel E. Exiner and purchased by Samuel's son, Richard N. Exiner in 1967. It was subsequently bought by Mark E. Exiner, Sam's grandson, in 1992. The current ownership will continue the Quality tradition as well as the mission, policies, ideals and goals of Samuel E. Exiner into the foreseeable future.
