Lee Allen’s unwavering commitment to outstanding customer service and to his profession served as the foundation to the establishment of Allen Roofing & Siding in 1972. Learning the industry one job at a time, he worked hard to build the firm into the highly respected local provider of quality exterior products it is today.


The steady growth of the company, in the interest of serving its expanding customer base, has resulted in the addition of Caseyville, Illinois, and St. Peters, Missouri, locations. The firm has also enhanced its services by the addition of Schwidde Tuckpointing as a division of Allen Roofing & Siding.
