Great Lakes Roofing and Insulation Systems, Inc.

For over forty years, Great Lakes Roofing and Insulation Systems has been completing commercial roofing projects across Michigan, from Sault Ste. Marie in the eastern Upper Peninsula to Grayling and throughout the northern Lower Peninsula. The company has installed more than nine million square feet of roofing material across 1,600 completed jobs. As a Duro-Last Platinum Contractor, the firm specializes in single-ply PVC roofing systems engineered for commercial and industrial applications. Metal retrofit roofing provides another option for facilities looking to upgrade without full tear-off. The roofing expertise pairs with comprehensive insulation services: cellulose, spray foam, and fiberglass applications for commercial buildings seeking energy efficiency improvements. Membership in the National Roofing Contractors Association and the Insulation and Coatings Association reflects ongoing commitment to industry standards. Active participation in both the Sault Ste. Marie and Grayling chambers of commerce demonstrates local investment beyond business operations. Chippewa County and the surrounding UP region experience some of the harshest weather conditions in the state. Heavy snow loads, extreme cold, and rapid temperature swings demand roofing systems installed by crews who understand these challenges firsthand. Great Lakes Roofing has built their four-decade reputation on delivering results in exactly these conditions. The company describes themselves as part of Michigan fabric, not just a contractor passing through. That kind of regional commitment shows in how they approach each project and why their Google reviews average 4.8 stars.
