Duffy Roofing Co., Inc.

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!

Brett Duffy oversaw everything in the most effecient and effective way possible. The company did everything promised in the time frame promised. I was consistently impressed by their superior service and the results. They were the Best! After the job Was completed I needed legal document information. Brett got it to me the same day, such excellent service is quite rare!!!

Review of Duffy Roofing, Co., Inc., Dorchester, MA If you have the good fortune of owning an 1897 house with a-200-year black munson slate roof, then keeping it in good repair is good conservatorship. Such is our house, and we have used Duffy Roofing Co., Inc. on two occasions (in 2016 and 2025). They have the knowledge and expertise to thoroughly evaluate the roof’s condition and to expertly repair it. The first job was focused on leakage around the base of the chimney, installing a new rubber roof on the flat area, and installing aluminum fascia on the wood fascia for entire house, complete with snow-bolting the new gutter system and connecting it to the existing downspouts. More recently, they located and repaired a roof leak from the vent pipe into the kitchen, and installed new copper hip and ridge caps. We have always been impressed by Duffy Roofing’s professionalism and excellent workmanship.

I am extremely satisfied with the overall performance of Duffy Roofing. Duffy Roofing was easy to work with. They were friendly and accommodating. The work was done cleanly and diligently. Would recommend Duffy Roofing to anyone looking for a roof replacement.

I am extremely satisfied with my roof replacement. The crew did a meticulous job under challenging weather conditions, and the roof looks beautiful. Everyone, including my main contact Garrett Duffy, was extremely detail oriented which I needed and really appreciated. Communication with Garrett was prompt and excellent as well. Don't hesitate to hire them for your next roofing project.

Definitely a 5 star + experience with Duffy roofing from start to finish Brett Duffy was a pleasure to work with - responsive, easy to communicate with, and understanding of what some might consider nit picky questions and expectations. Brett was on site daily, checking in with crew and homeowner, The crew was very professional and took great care in protecting the house and landscape from any roofing related damage. The job was completed in 2 days as. promised and the clean up was immaculate - no roof debris or stray nail to be found. Most importantly, the finished roof looks beautiful/handsome from the ground and from the air as well, as evidenced by the drone pics Brett provided at completion of the work. Bottom line - 100% pleased with the the Duffy Roofing experience and the end result.

Greetings, When seeking roofing Duffy is the right choice. I was referred to Duffy by previous owner of my home. The roofing had aged for approximately 20 years and was now on its final go. After reviewing other contractors I made a call to Duffy Roofing and Garrett responded promptly with a survey and quote to follow. He exhibited patience and professionalism as my timing was not immediately aligned. Once revisited Duffy once again responded and delivered with said responsiveness. They even offered to mitigate any leaks until parts and permits were acquired. My overall experience working with them was seamless and professional. I am confident I will get the warranted use of my new roof.

I echo Diana, Kristina, and Milton?s recent reviews! As a contractor from a multi-generational family business in Boston myself, Im very pleased. My experiences with the Duffy Roofing Co. and Brett was 5 star. He coordinated my large project throughout, overseeing a very skilled shingling crew that delivered results with speed, efficiency, and high quality. Phenomenal cleanup as well. My highest recommendation.

Duffy was extremely easy to work with, got the roof-replacement job done quickly, and at a competitive price. No surprises, no complications. Definitely recommended!
