Gannon Roofing Supply was founded in 1979 by roofing professionals to offer better products and services to the roofing industry in central Iowa. Since our founding, Gannon has expanded to three locations in Des Moines, Cedar Rapids, and the Quad Cities. These three locations have enabled us to expand our service area to include all of Iowa. Our desire to be the best in the industry has served as a catalyst for the many services we provide today. Thank you for visiting the Gannon website to see what we have to offer.
Gannon employees promise to provide superior customer service every day, all day. We strive to be friendly, responsive, and professional. We will respond to all customer inquiries, requests, or complaints as soon as possible. We do what we say we will do with appreciation and respect.
