Our Take on Green Peaks Roofing

Green Peaks Roofing pairs a perfect 5.0 across 211 Google reviews with a rural-edge base that suits farm-country and suburban Hamilton roofs. Customers consistently credit Chris and Lewis for honest estimates, quick leak response and clean job sites. Price is the trade-off, so compare quotes, and verify WSIB and insurance before signing.

  • Mike Richardson5.0

    Green Peaks Roofing came to my rescue a short while ago, and I appreciated their flexibility, clarity, patience, and promptness. I had a leak in my roof, and I reached out to a number of local roofing companies (including the one who replaced my shingles 7 years ago) for help, and Green Peaks was the first to respond. They were very accommodating, and came by right away while working on another job nearby. While inspecting my roof, Chris took lots of pictures and a video showing the damage. When he came down and showed me, he was very patient and clear while explaining what he found. He gave me his recommendations, which included getting in touch with the company that did my roof so I could take advantage of the warranty. I definitely got the sense that he prioritized my own well-being and satisfaction. When I need roof work done in the future, Green Peaks is going to be the first company I call. I was incredibly impressed with their professionalism and clear communication about everything. They helped make a stressful situation far more manageable!

    We recently had Green Peaks replace the roof on both our house and barn. Chris & Lewis were honest about their assessments and the entire crew were courteous and easy to work with. Very professional. We replaced the shingles on the barn with a metal roof per Chris’s suggestion (Good call). Synthetic underlayment covered with sturdy metal panels. Looks great and should last a long time. The older section of the house consisted of tongue and groove planks which the previous installer claimed to have covered with plywood but, turns out, did not. They made sure it was done this time, properly, and the remainder of the installation included water/ice membrane, new flashings, ridge capping and animal proof vents. Beautiful job. They also made sure that the surrounding areas were clean of nails and other debris. Certainly not least of all, the pricing was honest and reasonable. I would recommend Green Peaks to anyone looking to get either a smaller or larger job done on their property. Thank you, Gentlemen!

    Great job by the entire team. Owners were on site the entire time. Job done in one day. No hidden cost. Thanks Chris and Louis. Will definitely recommend your company.

  • Laurie Deptuck5.0

    I was extremely pleased with everything about my experience with Chris and Green Peaks Roofing. I had a quick reply and roof inspection done within days of contact, which was amazing because I had water coming in with heavy rainfalls. I really appreciated the honest advise as to what I needed repaired and never felt pressure to do more than that. The price was very fair and talking to Chris was like talking to a friend, so easy to deal with and again such quick responses to any questions. I would highly recommend them to anyone !

    My dog decided to test out her career as a professional escape artist today and broke out of the yard. These absolute legends intercepted my furry fugitive, kept her safe, spoiled her, and looked after her until I could get there to bail her out. 10/10 service, though I’m pretty sure my dog is already planning her next escape just so she can hang out with them again.

Company Background

About Green Peaks Roofing

Green Peaks Roofing works out of 4024 Woodburn Road in the Glanbrook area of Hamilton, where the city's suburbs give way to open farmland. That rural-edge base shapes how the company talks about roofs. Its own Binbrook page points out that homes surrounded by fields take more wind uplift than sheltered city streets, and a homeowner on its site describes a house and a barn both reroofed, the barn with metal panels on Chris's suggestion. Chris Giankos is president and Lewis Sutton is vice president. On Google, customers praise Chris for a fast emergency leak repair, honest estimates and a careful cleanup, and Lewis for explaining the process plainly.

The company installs asphalt shingles, metal roofing and TPO, EPDM and modified bitumen flat roofs. It also repairs leaks and storm damage and does eavestrough, gutter guards, siding and attic insulation. Green Peaks is a CertainTeed ShingleMaster contractor and says it is insured and WSIB covered. Its pages mention GAF and IKO shingles as well, though the guarantees page lists only the CertainTeed credential. Work carries a 25-year workmanship guarantee, and financing is advertised from $49 a month on approved credit. Beyond Glanbrook it serves Binbrook, Stoney Creek, Ancaster, Dundas and Waterdown, plus nearby cities such as Burlington and Oakville.

The rating is 5.0 from 211 Google reviews, read October 13, 2026. The one repeated caution is price: a reviewer said the company is not the cheapest option, though the final bill matched the estimate. Google lists the office as open 24 hours, while the website posts weekday hours of 7 a.m. to 8 p.m. with 24/7 emergency response, so ask how a routine call is handled.

It suits homeowners and rural property owners around Glanbrook and Binbrook who want a family-run crew and a written quote. It suits less well anyone shopping purely on lowest price. Before booking, ask for the WSIB clearance certificate, which can be verified on the WSIB site, and proof of liability insurance. Ontario does not license roofers provincially, so also confirm the CertainTeed ShingleMaster status with CertainTeed.
