"All Under One Roof recently replaced my roof on a 3-story, 200+ year old Federal in Newburyport. It was a big job that entailed removing 3 layers of rolled roofing/asphalt shingles; removing original skylight & taking down old dormant chimney to roof line and roofing over both; installing ½ “ plywood and asphalt shingles over new roof. I can’t say enough good things about All Under One Roof. They had a great crew and did a fantastic job. In fact, my neighbor across the street who had a birds eye view of work in progress, then hired them to replace his roof. John Lanzafame, the company’s owner, is a jewel. He’s very professional, responsible and communicative – a “take charge” guy in the best meaning possible. I was completely comfortable and confident that I was in good hands, and did not have to worry about micro managing the work. I should also point out that All Under One Roof began work on date scheduled (a month in advance) and completed the job (start to finish) in short order. I highly recommend All Under One Roof. Have dealt with various contractors for numerous issues over the years as I own several rental properties, and this has been my most positive experience by far. Kathy Quill"

"I had a roof replaced on m detached garage including all wood. Also had a small flat roof replaced. Both were in bad shape and for the flat roof that I had to redo the joists and outer wood. I have used them twice now and in both cases they were very responsive to phone calls and was able to schedule both jobs very quickly. In both cases they took their time to make sure the underlying surface/wood was replaced and fixed prior to roofing."

"Fantastic! The estimate was clear and detailed appropriately. The product selection was high quality and appropriate for our project. The roof project ended up taking 1.5 days and not the originally estimated single day but I was pleased they didn't try to reschedule the remainder and instead simply arrived the next morning, completed the work, and cleaned up the yard well."

""Newton Roofing" had done work for me 25-30 years ago. I didn't know the name had been changed to "Newton Roofing Residential", and was under new management/ownership.I called and Mr. Melo answered right away. I explained the problem. He personally came to inspect the following day. I had feared a new roof might be needed, but he explained the damage was likely caused by a damaged (perforated) shingle. One of his crew came out 2 days later and replaced the shingle. The price was reasonable. I also noted another shingle that lifted, due to a "nail-pop". This, a relatively minor matter, was repaired at no extra charge. I cant' recommend Newton Roofing Residential strongly enough. They were prompt, efficient, professional, and polite. Mr. Melo took the time to explain matters to me in detail. I will certainly be using them for roofing matters in future,"

"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"

"Many thanks to Matt Cabral and his expert team for a great job this week replacing a fair percentage of the trim on our thirty year old colonial. After the bad storms this winter, I noticed a small corner of trim had actually come off exposing the sheathing underneath. Fearing water damage, I called Connell Roofing who had put a new roof on our home 12 years ago (that looks as good as new), and did more modest trim replacement 6 years ago. Dennis and John were out the next day, reviewed all the trim around the house that had some damage, gave an estimate, and said they could start in only a week. While our house has sturdy cedar board siding, the trim boards are soft pine, and there were multiple areas of sunken wood consistent with rot underneath. The bad pine trim was to be replaced with PVC trim that will last a lifetime. When the day arrived for repair, Matt Cabral made another assessment and spotted a couple of additional trim areas that could be seen to need replacement now that"

"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."
