    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 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.

Frequently Asked Questions About Duffy Roofing Co., Inc.

How do I know if my roof needs to be replaced?

A roof replacement may be necessary if your roof is approximately 20-25 years old, exhibits noticeable damage such as curled, cracked, or missing shingles, shows indications of leaks or water damage like stains on ceilings or walls, or if you discover shingle granules in your gutters. These signs suggest that your roof may have reached the end of its serviceable life.

What is the process for a full roof replacement?

A full roof replacement begins with a comprehensive inspection to evaluate your roof's condition and provide a cost estimate. Following this, the existing roofing materials are removed to examine the decking. Any damaged decking is then repaired or replaced as needed. Subsequently, new underlayment and shingles are installed. The process concludes with a final inspection to ensure proper installation and thorough cleanup.
