About GC Commercial Roof Systems

At GC Commercial Roof Systems, we believe your roof is more than a structure—it’s your building’s first defense against Michigan’s tough weather. For over 35 years, we’ve helped businesses and homeowners across Macomb, Oakland, Livingston, Wayne, and surrounding counties protect their properties with durable, long-lasting roofing solutions.


Founded as a family-owned company in 1988, we’ve grown through referrals and repeat clients who value our honesty, workmanship, and reliability. Today, we’re large enough to take on complex commercial projects across Michigan, yet small enough to give every client the personal attention they deserve.
