"The Project was a complete success from start to finish! Elias, the Project Manager was excellent. We had a major problem with a roof that was leaking . We had several contractors come to look at the roof for estimates. Elias spent the most time of any of the contractors viewing and evaluating the roof and siding as well as the inside of the house where the water was leaking into and discussed the project with the President of Beantown. He was excellent at explaining what needed to be done. It was not your average "roof job" as the roof abutted a large chimney and the room under the roof was cold and drafty. He was very patient with me as I had many questions about the project. Janice, the Office Manager, was courteous and always available from start to finish. The roofing team was very professional and did an excellent job. They also added the appropriate insulation, new siding to the house by the roof, gutters and appropriate flashing. The roof not only looks great, but the room beneath the roof is no longer drafty and there are no leaks. His team cleaned up after the project was completed such that you wouldn't even know they were there. Elias was so professional and he even contacted us after the first rainstorm to make sure that everything was fine. The Office Manager, Janice sent the Roof Warranty to me right away. If you are looking for a Company to do a solid, professional, worry free project from start to finish, then go with Beantown Home Improvements. Thank you again for doing such a great job!"

"John came in today on a holiday day to check my roof. He is a very honest man. He told me my roof is still good for another two years, and doesn’t need any repairs at this time. I highly recommend him for any roofing projects. Thank you John!"

"I've worked with Moacir and FRS roofing and gutters twice. In 2019, they did an excellent job installing a completely new roof. I was happy to hire them again in 2021 for a rather complex repointing/masonry job on my garage. Their pricing was fair, and when you factor in their professionalism and courtesy, you're getting a great deal. I recommend them highly."

"Adam Vaillancourt Roofing was the 3rd roofer to inspect my very simple repair job (replacing a single edge shingle) and the estimator (Adam) was the only one of the 3 to offer a repair right away. I hired him on the spot and he completed the job in about 1/2 hour for less than what the others quoted. Very happy with the outcome. Would hire this roofer again."

"Fredy and Andrea at Global Roofing combine to provide excellent customer service with high quality installation. From quote to complete the entire process was smooth. We were looking at metal roofing first and learned quickly that these folks know a lot about the options, potential issues and installation. Ultimately we went with CertainTeed asphalt shingles due to supply chain price increases for metal, a limited color selection, and because I tend to walk on my roof for a few reasons. On the 1st scheduled day the crew arrived on time and ready to work. They hung tarps and netting to collect all debris and protect shrubs , etc. They moved fast and efficiently with a big enough crew to clear old shingles and start installing new by mid-afternoon. At the end of the day they cleaned everything up, and I do mean everything. By end of day two they were done, once again cleaning everything before leaving. We were very impressed with Global and definitely recommend them for your roofing project."

"I couldn’t be more satisfied with the work done by Robert Evans Jr. Contracting. The price was fair, the work was exceptional. The crew was obviously very experienced and was very meticulous about their work. The crew chief kept me informed of their progress, any issues they found and how they were addressed. They did an excellent job cleaning up the entire site before leaving. Within a couple of hours of my initial contact I had a date for a visit to review the project and provide an estimate. I received the estimate later that day by email and was pleasantly surprised by the reasonable quote and timing was only two weeks and that it would be a two day job. The crew arrived exactly two weeks later and at the end of the first day all of the original roof was stripped and 80% of the installation of the underlayment, shingles and trim was complete. They finished on day two, and after they finished the entire crew did a site walk around looking for anything they had missed. I would definitely recommend Robert Evans Jr. Contracting for all your roofing needs."

"We called Power Roofing when our 3-year old membrane roof began leaking. They sent someone over within 24 hours, quickly identified the reason for the leaks (defective installation by a different roofing company), told us the necessary fix and how much it would cost, scheduled the job, ended up coming a week early to take advantage of favorable temperatures, and invited me up on the roof (twice), first to show me the problem and then to take a look at their work once they were done. They honored their estimate even though the job took longer than expected. And the leaks stopped. An A+ experience from start to finish."
