GM Systems Inc.
Started in 1999 by the owner Greg Stierwalt focusing on addressing a need by providing an affordable solution to fix a leaking or damaged roof by the application of spray on elastomeric roof coatings. Currently we specialize in the application of high solids silicone roof coatings as well as the installation of single ply/membrane roofing systems. We now have a full suite of products to meet any need a commercial customer may require whether it be the waterproofing/sealing and repair of an existing roof or a new construction project.
