Roofing & Gutters reviews in Manchester, New Hampshire

I did a lot of research and talked to several roofing companies before I went with John. He is prompt, honest, dependable and had excellent communication and kept me informed the entire time. He wasn't the cheapest or the most expensive but was very insistent on a couple aspects of the job that other companies just passed over. His pricing was all inclusive vs. other companies that had separate charges. The crew was diligent, professional and did a great job on my roof and at keeping the grounds clean and safe. Any issues that came up were immediately addressed. I hope to do more business with John again.

I highly recommend John Denisco for your roofing solution. Upon meeting him the first time for a quote, he was amicable and professional, and it was clear he has passion for his work. He assured me that my roof could be replaced in a day, and carried excitement and energy as we discussed how the whole project would go down. I was very impressed with his motivation for taking on the work, and could tell he was head and shoulders above all of the other quotes I got due to his honesty, energy, and integrity. And all of this was before the roofing crew showed up!
On the day of the roofing job, his crew arrived early and were very efficient and professional. Within 3 hours, the whole roof was stripped, and by the early afternoon, my new roof was completed. My wife and I were very impressed with how beautiful our new roof looked, and grateful to John and his crew for the job well done. They did a great job cleaning up the property before leaving, and triple checking the ground around the house for nails and debris.
Every interaction I had with John was positive. His quote was spot on, and his follow through far exceeded our expectations. We are extremely happy with his work.

John and his crew are amazing. John and his guys did awesome work. They finished the entire job in 1 day. John spent extra time with me (2 visits to my house) to figure out a solution to the improper roof ventilation on my colonial house. He ended up cutting in a ridge vent and installing some vented drip edge, which now allows my roof to properly vent. He not only replaced my roof, he also solved a mold problem in my attic. I would recommend John to anyone. If I ever need roof work done again, I will hire John.

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.

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,

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.

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.
