Get matched with top roofers in Sudbury, MA

"We are very pleased with the result. The job was done in a day by a large team, who wrapped up the house (!), stripped off the old roofing, and put in the new skylights and roof within the day. There were some delays due to poor (wet) weather, but we can't really blame Ranch Roofing for that."

"On Top Roofing was great. Tim came to quote the work and asked what I wanted and offered excellent suggestions. He wanted to vent two bathroom fans out through the roof to reduce the moisture buildup in the attic. No other roofer even mentioned it. He also wanted to replace all drip edges and re-led the chimney. Several others wanted to reuse the exiting drip edges and led. Given all that his price was still very good. The job took two days. His crew was efficient and the roof looks great. There was a supervisor (Mike) on the job the entire time who ensured everything went well. They had one guy who did nothing but clean up constantly. So the yard and surrounding area was always clean. When they left they swept, rakes and picked up everything. Very professional and courteous team in the field and in the office (thanks Kelsey). All this and a 10 year workmanship warranty!!!"

"Amazing company, work was done perfectly. They waited for a few rainstorms to make sure roof didn’t leak before payment. I will use them when I’m ready to replace the whole roof. Honest and reliable."

"I had leaky roof. Of 3 contractors who came to take a look, only Ramon from NMTI pointed out an uneven surface that seemed to be good place to look for an issue. I appreciate hearing specific ideas when there’s a problem, so we chose to work with NMTI. Sure enough, underneath the shingles on that section of roof, there was some water damaged and warped plywood. The NMTI team addressed that and re-flashed some skylights at the same time. The team was all very pleasant. They scheduled the job quickly, once we agreed on details and I would work with them again. Thanks, guys!"

"After our roof began to leak, we had it replaced with a power roof. It was completed in one day by the crew. I'm very impressed."

"Initially they were responsive and got to the job quickly. They started one day later than their initial estimate and finished the job in a day and a half. The roof has gone through the Arthur downpour with no apparent leaks.
The cleanup wasn't perfect, as there were small pieces of old roofing and cellophane strips left on the ground. In a couple of places where the roof changed direction the shingles didn't conform fully to the shape leaving some gaps. Also, when they reflashed around the chimney they put the new flashing one course above the old flashing, rather than digging out the old flashing and inserting the new material in the same place.
When I called about the issues they were pleasant, but it took a few weeks for a representative to come out and review things, and then three more weeks for them to come to resolve the first two issues. The flashing is just the way they do things and is OK.

"Quick and easy. Roof looks great."

"Excellent repair job "roof tune up" to my complicated skylight, chimney, plumbers exhaust, venting and moss issues on a roof only 13 years old"

"I got 3 estimates for replacing the roof. Willard was in the middle of them. I picked them because 1. the company has been around for a long time. 2. The person who estimated the job was very good to deal with even though I never ended up meeting him. His name is Danny and he was very responsive and patient in answering questions. I found it easy to deal with their main office.
The job was done over 2 days (winter days being shorter). The roof looks good and is guaranteed for 10 years labor with a lifetime on the shingles. 
The scheduling worked fine and was convenient for us.

"They beat out the local contractors by quite a bit. I was able to get the roof done plus gutters for less than what the locals were trying to charge just for the roof. Very easy transaction, they were in and out and the day and they cleaned up their mess. The roof looks fabulous!"
