Great Lakes has not upheld the 15-year warranty for our church roof. They have been dragging out approving repairs for 8 months.

I don’t think their roofs hold up over time. We initially had seam issues the promptly fixed. But they did a poor job of flashing where the flat roof met the walls. …

Reckless drivers. If they are that careless about a life of a fellow driver who says they will care about a roof.

I used them to try to solve an issue with my flat roof that had been a problem for a few years. I paid them $1500 to do some patch work which they said they fixed and guaranteed the work. After 2 months the same place continued to leak. …

I had a great experience with George and his team. They responded immediately when we had a roof issue at Ewald's Hartford Ford, came out right away, and fixed everything on the spot. Their service was professional, efficient, and hassle-free — exactly what you want when something needs urgent attention. Highly recommend them for any roofing or repair needs. Thank you George and Randy for the outstanding service! Scott General Manager, Ewald's Hartford Ford

GLRC recently replaced all of our gutters and downspouts, adding thermal wiring for wintertime. Quality of materials and workmanship are the highest level possible! Guys were great to work with and completed the job on time. Would highly recommend to everyone for any roofing needs.

Thank you for the recommendation! Roofing solutions often include more than the roof.

I had two leaks at different areas in the plant. They were able to sneak us in last Thursday, before the big storm. Repairs were done in a prompt and professional manner. The main leak was over the main power panel for the plant. Repairs …

Our church building had an old flat roof that need a lot of repair. Great Lakes Roofing was responsive and helped us maintain that roof for several years, until we made a new plan for our aging building. All staff listened to our needs, didn't try to upsell us, were prompt and effective in their work! We appreciated their efficiency and customer service in every step of the process from scheduling to the roof repair to answering questions on billing.

Grateful we could be your trusted partner and provide on-going commercial roofing solutions. We're with you for the long haul.

★★★★★ Great Lakes Roofing has been fantastic to work with. We utilized them at our Azura location, where commercial flat roofs can be challenging due to the number of HVAC systems and equipment on the roof. The building had been vacant for years before being remodeled, so the roof required careful inspection and repair. Their team was knowledgeable, responsive, and easy to work with throughout the process. What stands out most is their follow-up and follow-through—any time an issue arises, they respond quickly and come out to Azura right away. Highly recommend their team for commercial roofing needs.

Where this page comes from
Every figure above is Google’s, captured on 24 September 2026. The star average and the 80 ratings behind it are counted by Google across all of its reviews. The review text on this page is a sample — we hold 80, of which 72 have any text — and it is not everything Google shows.
Roof Warden does not verify licenses, bonds, insurance or workers’ compensation cover, and nothing on this page should be read as though we had. Confirm those directly with the contractor and with your state or provincial licensing body before you hire anyone.
