Meet The Owner

“GM Systems was founded in 1999 by Greg Stierwalt, in a bid to address a need by providing an affordable solution to fix leaking or damaged roofs. Leveraging on elastomeric roof coatings, we currently specialize in the application of high solids silicone roof coatings as well as the installation of single ply/membrane roofing systems.

Thriving under Greg’s leadership, 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. In this sector, having a niche business presents a number of difficulties as well as opportunities; yet, in the end, the company must still perform exceptionally well and provide products of the highest possible quality in order to be successful.

Greg attributes a significant portion of the company’s accomplishments to both the team at GM Systems and years of industry experience that has made possible the level of quality commercial roofing service GM Systems offers.
