"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."

"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"

"I had a jug of the recommended product, which Mr. Dexter used to spray the entire roof--not just the bad sections. He expertly corrected a downspout position to direct rain into main gutter. Two gutter covers were replaced with white-painted, seasoned wood, which were cut to the proper shapes. A deck board was fastened securely. Mr. Dexter plans to return to inspect his roof work. If additional roof treatment is needed, there will be no additional cost for me. [I had contacted 2 other roofing companies, which were recommended by Angie's List. One company did not respond. A 2d company gave a $930 estimate, which did NOT include spraying the roof for moss/algae.]"

"I am very pleased with the roof replacement. The workers were very thorough, neat, efficient, and professional. During the project they noticed a lot of rotted wood and were able to repair that as well. From the entire process - initial meeting; sales; work performed; and cleanup; I have nothing negative to say. Outstanding work."

"I recently had FRS Roofing install a roof on my home. I was impressed with the way they conducted business, and I am very happy with the finished product. One of their salesmen, Joseph Costello went on my roof and filmed the issues he saw that needed attention. He showed me a video on his computer of the inspection he had just completed of my roof. He then showed me his suggestion of what should be done and also had samples of the materials that FRS would use on the roof replacement. I was impressed with the materials that would be used and chose FRS to replace my roof. I watched the roofers replace the roof and perform the work and cleanup. After the job was complete Joseph Costello once again went on the roof and filmed the finished product for me to view on his computer. Very happy with the entire process, Thank You."

"We bought our home in Groveland, MA about a year ago, and our roof was in pretty rough shape.  We got three different quotes, and Mike had the lowest price of all three quotes.  He was incredibly responsive throughout the entire process, and got back to us within minutes every time.  He really took the time to explain all of the issues with our roof, what he planned to do, and all of the products that he was going to use.  I was really impressed with the detailed brochure that he gave us; it explained everything about the shingles, the warranty, etc.  The warranty was great.  The other two quotes I got only insured the shingles/work for 10 years, where Mike's warranty was for 50 years!  That really gave me the piece of mind that if I had any issues, Mike would be back to take care of them.  Both Mike and his crew were incredibly personable, and did amazing work.  The roof looks absolutely beautiful, and has really increased the overall appearance of our home.  My wife and I still just take the time to stop and admire the roof.  We probably need to get a life, but these things are exciting when you get old.   The cleanup was impeccable.  I literally could not find one roofing nail in the yard after they were done.  I have another rental property in Haverhill and I plan on replacing the roof as soon as I save up the money.  I would not call anyone else but Mike after this experience.  I would highly recommend Mike if you have any issues with your roof.  You will be 100 percent satisfied.

"They were the least expensive amongst the 3 bids I had gotten for this project. I received an Angie's List member 5% discount from the coupon offered on the Angie's List website. The job was originally estimated to take 2 days, but it ended up taking 2.5 days due to the change in DST. The owner Ten (short for Tenzin) was easy to talk to and very helpful and knowledgeable. I would be happy to use them again if I had another roof replacement project. Overall I had a great experience with Arya Roofing."
