See What Our Customers Say
“They arrived to my house as originally scheduled and were in and out in no time. The experience from start to finish was efficient, professional and fair, and all expenses were exactly as originally discussed – no games! I would recommend WM Green roofing to any of my friends and colleagues.”
— Phil T
” I was very satisfied with the service and quality of work from the crew at Wm. Green. Jesse was prompt to come out and provided a straight-forward quote and truthful assessment of the state of our roof. Communication and customer service was first-rate. Very respectful and good at explaining things with no machismo/mansplaining. They registered the warranty for us and it came in the mail a few weeks later. Highly recommend. “
— Marie G
