Terrible. Signed a contract in June to repair our roof/gutter and gave them a deposit. They did not do the job and are no longer returning our emails or calls. Nor, have they returned our deposit as requested. It is now November. No stars should be an option. We wrote this review and a reply was immediately made indicating that there were supply issues and offered to send our deposit back. It was amazing to see how quickly they responded when a negative review was received. It is now December 5 and we have still not received our deposit back. Seems they have a supply issue with their company cheques

TLDR;
Old roof = Bad roof
New roof = Great roof
WM Green = Great Company, 100% Recommend
DIY projects = Not for everyone...
WM Green was referred to us by a friend and we could not be happier. We bought our first house this year knowing the roof needed some work. Being an old house the roof had a significant bow to it, the shingles had seen better days and the DIY repairs were.. interesting to say the least. Though a small house, we knew it was going to be a bigger job and were quite nervous how it would turn out. Nick and his team nailed it. The crew did an amazing job and Nick was very

First of all, dealing with Jack is wonderful. He's personable and honest. The crew were also amazing. They worked so well together. When they arrived, everyone knew exactly what to do to get the project started. They moved or tarped my outdoor furniture and plants to protect them. I highly recommend Wm Green Roofing.

Wm Green Roofing just completed the removal and re-installation of shingles on my Century home. It was a tough job with a steep pitch, rear addition, front porch, valleys, etc. Jessie, Jack and Paul provided excellent service from the quote, through project coordination, to finish. This was all accomplished in very hot summer weather. Paul's crew did a first-class job on the roof and installed new Velux skylights. Moreover, they did their work safely, cleaned up the job site, and explained every step of the process. My new GAF Timberline shingles also look great on this old Victorian home. After
