Residential & Commercial Roofing

Allen Roofing & Siding has been a leader in the roofing industry across the metropolitan area since 1972.


Allen Roofing & Siding has been providing structural integrity and safety to homes since 1972. With your roof being such an important aspect to your home, it helps keep you and your family safe and dry from rain, snow, and mother nature. Because of the importance a roof holds, you want to choose an experienced roofing company who always has your best interest at heart. This means that you shouldn’t wait until small issues become big problems. If there’s a minor roof leak, torn shingle(s), weather damage or more, this can cause greater external and internal damage.

Whether you’re just wanting to take precautions, wanting some small repairs done, or have a new roof installed, Allen Roofing & Siding can provide you with a large amount of choices at a great price! Our team has served the St. Louis Metropolitan area since 1972


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.


Whether it’s new or existing residences, businesses, schools, churches, or public buildings, no job is too large or too small for Allen Roofing & Siding. In fact, it is now one of the largest and most experienced exterior product companies in the entire metropolitan area.
