  • "If you are looking to have a roof replacement, Denisco Construction is the company to choose. John and his crew did a beautiful job installing my roof. They arrived in the morning, tarped and moved everything to ensure no damage to bushes, patio furniture, etc. The job was completed the same day which was pretty amazing. The team cleaned up and put everything back to where it belonged. Such a wonderful experience! A big thank you to Denisco Construction!"

  • "I had a new roof installed by John Denisco Construction Company I could not be happier with the finished results and warranty on the roof. The day of installation was great John and his crew came at 7:30 done by 4:30 . They where very professional and fast and efficient clean up was great. I would highly recommend John Denisco Construction Company could not ask for better service. Great Job"

  • "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."

  • "John's crew did a great job with our roof job on our house and detached garage in less than one day. Recommend."

  • "John was amazing from start to finish. He came out on a Sunday morning to take a look as I was having issues with water coming in through my walls. We had just bought our house a couple weeks prior to this issue arising and we're told the roof was new. John recognized that the roof was new but took the time to show me all the mistakes the company made during the installation. He spent the entire afternoon by himself fixing the area were water was coming in so at least no further damage would occur until the real issue could be solved. After working all day I asked him the total and he told me not to worry about it. Within a couple days he had a proposal sent over to me that was extremely reasonable and once I gave him a verbal agreement him and his crew were here 2 days later. He took the time to show me the damage that was underneath the roof (all rotted wood) and replaced it all efficiently. They finished the whole job in one day. His crew was also very professional and friendly. We had spoken to a few other company's prior to John's and honestly couldn't be happier we chose his. Highly recommend!"

  • "They did a GREAT JOB. Very happy with the work and price. The crew worked hard and completed the job in one day. When they finished the job, they all cleaned up like nothing happened. One of the things I liked the most, a guy went around the whole house with this magnet on wheels to pick up any lost nails. This was great cause I have my grandkids running around with no shoes. Highly recommend this company for any future work you want done."

  • "John and his crew did an amazing job replacing our roof. His crew was here within a week of giving me an estimate and they had the job done in two days. They were fast, efficient, respectful and honest. John was my contact person from start to finish and he is extremely knowledgeable and stands behind his work. He not only replaced my roof but he also helped solve my ventilation issue which was a big part of why the original roof failed. He could have just replaced it and took my money but he took the time to find a solution to make sure it was done right. They installed asphalt shingles as well as a rubber roof on our Cape, now our roof looks amazing. He even came on his own time to help correct a mistake a previous contractor had made. He stands behind his work which is so hard to find now a days. I highly recommend John and his team!!! I would hire them again in a second"

  • "I never really appreciated a roof until John Denisco and his team replaced ours. Now, I find myself frequently admiring the beauty and quality of my new roof. From the very beginning of the bid process, John excelled at communication and demonstrated a superior level of professionalism. Once selected, John delivered on his promises and made the entire process enjoyable. He and his team are real craftsman in the art of roofing. The quality of the materials, protection of our shrubbery, to the expertise and attention to detail on installation all exceeded our expectations. John also provides an unparalleled warranty on his work that gives additional piece of mind. I heartily recommend John Denisco to friends and neighbors and to you as well. Randall & Debra B"

  • "Wonderful job at a fair price. John was great to work with and communicated well and often through email and text. His crew worked hard did great work and did an excellent job at cleanup after. He came up with solutions to problems encountered that got the job done, looked great and didn’t break the bank. Highly recommend. I’ll certainly use him again if I need any painting or siding work."
