A 4.8-star average across 87 Google reviews, and another 92 landing almost identically on Birdeye — for a shop working out of Dorchester Ave, that's a lot of strangers agreeing on the same thing. Duffy Roofing has been at that address since 1958, when Joseph E. "Joe Sr." Duffy started the company; it's now run by his sons John and Joe, with grandsons Brett, Trevor, and Garrett Duffy handling jobs as the third generation on site. The reviews from this year keep naming the Duffy brothers directly rather than a generic crew. One homeowner had Garrett catch a drainage and pooling problem on a triple-decker roof job and fix it within 24 hours of it turning up; the same review mentions getting three quotes from licensed roofers and Duffy landing in the middle, not the cheapest but not padded either. Another job, wrapping up in early January, needed a legal document afterward and had it back from Brett the same day he was asked. Six new reviews have gone up in the last six months and none of them are negative, which lines up with a longer run of 55 reviews since 2021 spread across Google, Birdeye, and a couple of smaller review directories, all clustering in the high 4s. The one dissenting note, from a Consumers' Checkbook write-up, is that a job took a while to actually get started — once the crew showed up, the reviewer said the work moved fast and was clean, but it's worth pinning down a start date before signing anything. Duffy's Massachusetts home-improvement contractor license (HIC #100253) is currently active. Between the roofing and the gutter work the company advertises alongside it, this reads like a call for a full roof replacement or a repair job on an older multi-family home rather than a same-day patch — just confirm the schedule up front.

As we all know getting a reputable roof installer company with a market saturated with a million roofing companies is no easy task! I own triple decker in Dorchester and a flat rubber roof which was in need of replacement. I got about 6 different estimates and ended up choosing Duffy Roofing. I chose Duffy roofing because I felt like they were the most honest, reputable local company that has been around for years and stand behind their work. Garrett was amazing he was very communicative with all my needs and never pushy. The entire job was flawless from start to finish. Remember it not just about the quality of materials used but also the correct way of installation of what matters most in roofing!!!

Incredible service with reasonable rate. I was worried about everything but Brett assured me and all went well . I would use them again without hesitation.

I don’t often write reviews, but for Duffy roofing I need to make an exception. Fantastic quality work. Been using them for all my properties for the past few years, and have been indispensable for me during this winter storm surge. The only roofing company in Massachusetts I would ever recommend. 5star

Start with the best in Boston! Why call the rest first? Brett from Duffy Roofing clearly communicated the job and answered any questions I had. His team treated my property with the utmost respect and care. The job was completed in a timely manner. Quality workmanship and material cost more but why have problems later? Call Duffy first and last!

We had our triple decker roof repaired by Duffy as well as an external garage and deck. We worked with Garrett Duffy and couldn't be happier - despite inclement weather pushing the timeline back, Duffy was extremely communicative and when they were able to work did an excellent job. When we saw an issue with drainage / pooling they promptly took care of it within 24 hours. We received 3 quotes from licensed contractors and Duffy fell in the middle so we also felt we paid a fair price - we'll be keeping them in mind if we ever need roofing services again!
