GDC has been replacing roofs in Chicagoland and the North Shore since 2006. We use all of the best and most efficient products out there to ensure your investment. Our installers are certified professionals with decades of experience, and GDC guarantees all the work. We offer extended warrantees at NO ADDITONAL COST.


We are preferred installers with IKO, who provides a LIFE-TIME WARRANTEE on the roofing materials, *when professionally installed. With the varying weather we have in the Chicago area, it is important that your roof is installed by a contractor who is local, whom you can trust, and installs a reliable product on your home. GDC also installs flat roofs and is licensed, insured and experienced in commercial roofing.
