"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!!!"

"I was so glad our condo association hired joe and his company. Firstly, they carefully looked over the work, gave a good estimate. They answered questions I didn't know I had and explained the entire roofing process. They showed up when they said they would and he came with a large crew and got the work done in one day and it was hot! They did a wonderful job and did more than they had contracted for. A few weeks later we had a small leak. They responded immediately and took care of the problem. I am a trustee for a small (eight unit) condominium association. I would certainly recommend Hennelly and Son Roofing. Sincerely, Kathryn Collins Hyde Park, MA"

"I called Willard and they came later the same day and cleared the ice away. They were polite and professional and cleaned up after they were done. I plan to call them later in the spring to get our roof protected from more ice dams."

"- Very prompt, professional service delivered at a great price on our Newton expanded bungalow. - Owner, Brian (in business for 25 yrs) assessed/priced job and, with on-site job supervisor, was available at every stage of job completion. - I requested 4 references which Brian gave me at random but said he doesn't call former customers in advance of such requests so wasn't sure if I'd get call backs. All 4 references DID return my calls and all raved about Roofer's Edge/Siding work and value. - Also, work crew included professional women which I appreciated. - Policy is payment at the end of the job when customer is satisfied. - Will definitely use again for siding and or windows given this roofing experience."

"We had a wonderful experience working with FRS Roofing right from the start. Mike was very friendly in coming out on short notice and providing a detailed evaluation and quote for the work that needed to be done. His pricing was fair and of great value. His team came quickly and finished the entire project all in one day. They send folks the next day after to ensure our property was thoroughly cleaned up and to check in with us. I highly recommend FRS roofing to others and would hire them again"

"the work was great, he went in their and cleaned up everything, and put in a piece of pad to cover it to keep the birds out; he also checked every part of the roof for any possible entries as well."

"We had a roof repair that needed to be done fairly quickly. Lou showed up the morning after I requested quotes, walked the roof and gave us a fair quote for the work. He showed up when promised and did a terrific job making the repair. I will absolutely use Lou the next time I need any roof work done - very highly recommend!"

"I can’t say enough good things about Evans Roofing! My husband and I met with Dan who listened to every detail about our project replacing our very old roof and gutters Within a few hours that same day Dan sent us a very reasonable quote to do both roof and gutters. Within 1 week the roofers were here and the roof was done in 1 day Day 2 our gutters were done The clean up was fantastic! They left the site cleaner than before they were here!! The crews were professional, polite and very kind . We did meet with another Roofing Company prior who gave us a long sales presentation and quoted us 3 times the cost to do the same job but I won’t go there because I want this review to shine for a Evans Roifing! So if you have a roofing job and gutters done go with the compnanyvthat fits your needs but please consider Evans first Thank you Ps I wish I could show pictures but can’t figure out how ☺️"
