"All Under One Roof did an amazing job with my roof replacement. My roof was leaking for the last couple months so I decided before winter to replace. When they were replacing it I was informed and shown pictures of how bad the damage was. The roof has extensive rot in many areas. All Under went above and beyond and cut out all the old rot and replaced. They went into great detail to show me the rot and how it was leaking for years, but not into the interior of the house. I am so happy at how it came out and will recommend All Under One Roof to all my friends."

"1. punctual on estimate appointment 2. three estimates were solicited all were equivalent service for product two allowed for Owens Corning or GAF and were certified as was On Top 3. The date proposed was mid October but the actual work was much sooner (low slope roof) and completed in several hours The roof has now gone through several seasons without issue. I recommended them to a friend of my wife"

"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"

"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."

"I can’t say enough good things about Evans Roofing! My husband and I met with Dan who listened to every detail about our project replacing our very old roof and gutters Within a few hours that same day Dan sent us a very reasonable quote to do both roof and gutters. Within 1 week the roofers were here and the roof was done in 1 day Day 2 our gutters were done The clean up was fantastic! They left the site cleaner than before they were here!! The crews were professional, polite and very kind . We did meet with another Roofing Company prior who gave us a long sales presentation and quoted us 3 times the cost to do the same job but I won’t go there because I want this review to shine for a Evans Roifing! So if you have a roofing job and gutters done go with the compnanyvthat fits your needs but please consider Evans first Thank you Ps I wish I could show pictures but can’t figure out how ☺️"

"Lifetime Roofing is an outstanding contractor. The work was excellent, the price was fair and their communication was exceptional. After a heavy rainstorm, water was leaking into my house. Paul from Lifetime Roofing got back to me very quickly and, after an inspection, recommended that the flashing be replaced in one area of the roof. I was impressed that Paul kept in constant email contact through the contracting and scheduling process, answering all my questions. The crew was professional and skilled and completed the work in one day and did a terrific job. After the work was completed, Paul even followed up after a rainstorm to make sure no water had leaked into the house. None did. It was a very positive experience and I highly recommend this company. I will be using them for all my future 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."
