Excellent communication and service! I still can’t believe how fast they stripped the two layers of roofing shingles. My new roof is just perfect! Thanks for a great job at a fair price!
Only because it's not possible to give ZERO STARS. First, may I say we never hired them to do a roofing job. The attached photos are what I came home to. I asked why they were set up in our driveway with equipment, machines, ladders and they had their work truck parked in the other space we pay to have plowed. No one answered. Not one word. Not excuse me, not sorry. Nothing. I thought there could be a language barrier. My Spanish is minimal at best. I tried to speak to the person in charge and he was receptive to me in Spanish, but as I said I am limited. I called the "24 hours emergency line" I am still waiting for a call back. Please note the house on the right was having the roof done. They have a full driveway. This is how they chose to set up. The person that disperses the crew is responsible. As I said he has still not bothered to call.
I would highly recommend John Denisco and his company for your roofing needs. I did a thorough research of roofing companies for my home in Nashua. I had one company quote me $18,000 for my ranch style house. I had another company quote me $10,500. I was in sticker shock and then saw that 2 of my next door neighbors had used John Denisco & his company for their roofing needs. They told me that John was an easy guy to talk with and that he had done a great job on their roofs. I was familiar with John's company from my thorough research so I contacted him and got a quote. It was a heck of a lot less and the reviews on the internet were impressive so I decided to go with his company. The workers showed up on time and were friendly to talk with. They came in the morning and were done by the afternoon. John stopped by to ensure everything was going smoothly and stayed until they finished. I had a blast talking with John and we had some good laughs over various subjects. He even did some additional work for no charge. John's services are very fair and I appreciate the quality of work. I will be needing some siding done on my house in the future and will definitely be giving John a call. Again. I highly recommend John & his company for your roofing needs.Sincerely,Al
I wish I can give John and his team more than a 5 star rating. They were phenomenal from the time John came out to give us a quote, to the roof being installed. John quote was amazing, we not only needed our roof done but we also had 2 skylights that needed to be replaced. We had to make some changes to our scheduled because of COVID but John continued to make sure we were okay, and ready when able. When the team got here they moved quickly and smoothly. They took into account everything around the house to keep it safe and from breaking. They cleaned up our yard beautifully, and even replaced some of the stuff we moved out of the way. I would recommend Denisco Construction to anyone and everyone.
We got estimates with a list of materials from 4 roof contractors. John's estimate listed all GAF branded materials, where others listed only GAF shingles with unbranded accessories. And when the others matched all GAF accessories thier price was considerably higher. John's crew came early, completely removed old roof, installed all new GAF products, I was particularly impressed with the sheet metal work on the rain drip edge, perfect job. The roof looks great, John included a GAF Weather Stopper System Plus warranty, and Military discount. I could not be happier.
