Gannon Roofing Supply is a family-owned business. We supply quality roofing materials to professional contractors and builders. Over the years we have remained flexible in order to accommodate improved products and industry trends. We have served the Iowa and Western Illinois roofing market from our Des Moines location since 1979. In 1998, we opened our Cedar Rapids location in order to better serve our eastern customers. Our motto, "We are only entitled to the business we can serve," has allowed us to maintain consistent growth. We strive to partner with our customers and manufacturers in order to develop long term, mutually beneficial relationships. We conduct business with honesty and integrity at all times. This, along with our product knowledge and dedication to the industry, has earned us the respect of our customers as well as our competitors.

As our name implies, we specialize in roofing materials and accessories, both commercial and residential. We inventory commercial low-slope products from Gen Flex, GAF, PolyGlas, ATLAS, Georgia Pacific and others. For residential steep-slope, we inventory products from Certainteed, GAF and Malarky. We also stock quality accessory products from Lomanco, SFS Dekfast, United Roofing, Underlayments, Henry, Air Vent, and many others.

Our fleet of trucks enables us to satisfy your delivery requirements. We have "knuckle boom" cranes that will reach as high as 52 feet. Because these cranes are so versatile, we are able to lift rolls, skids, and large units of material. We can lift material to the roof or set it on the ground. We can also pick up or off-load materials from the roof if necessary.

All of us at Gannon's appreciate the opportunity to serve your roofing needs, and we look forward to prospering together.
