We manage a portfolio of commercial properties, so finding reliable contractors is everything — and this roofing company has become our go-to without question.
What sets them apart? Same-day service (yes, really!), fantastic communication, and a team that genuinely cares. From the first call or email with Bryce, right through to Tim showing up on the roof, every step of the experience is wonderful — the team is always knowledgeable, professional, and willing to go the extra mile. The whole crew is delightful, which honestly makes a stressful situation feel a lot more manageable.
They don't just show up and do the bare minimum — they take the time to explain what's needed, share their expertise, and make sure you're completely taken care of. Highly recommend to any property owner or manager looking for a roofing partner they can count on!

We had a major amount of snow on our roof leading to an ice dam. Put in a couple of calls to several companies. Bryce at Wm Green Roofing was great. He sent two of his crew to remove the snow and give us advice on the ice dam. The team was professional and knowledgeable and the cost was reasonable. We wouldn’t hesitate to contact Wm Green Roofing should the problem arise again. Thanks very much!

We had a roof and leaking problems and contacted Wm Green Roofing for a quote. They were very quick to respond with someone to come and identify the problem areas and overall roof condition. Jesse was terrific to communicate with and came over in person with a complete package of samples, a couple different quotes and shared recommendations and options available. He explained the new GAF advanced ridge venting which we decided to go with- it looks great too. Jesse was able to prioritize our job as we had a leak and the full team was able to give us a new roof in two days. They have a wonderful full team and did a great job removing roof and cleaning up all debris.We’re leak free and the roof looks terrific! Highly recommend this company! Ask for Jesse!
