  • "My wife and I had Tony replace our leaky old roof on our home recently. Tony is a truly dedicated professional who went way beyond our expectations. Any concerns were quickly dealt with. He was in constant communication with us the entire time and even after the roof was completed. You see a photo of before and after our chimney stack was covered with Stainless Steel. You also see the new GAF HDZ SHINGLES. He has a great crew of men led by Marco. He also is extremely diligent in his work. We couldn't be more pleased. They clean up their mess and leave nothing behind. We will definitely use them to do more work on our home because we are so pleased with their work ethics. If you're looking to get the job done right call Tony!"

  • "Tony and his crew were nothing short of amazing. I had a roof leak which Tony came out and rectified immediately. He was honest and fair from the beginning. He was so patient with me changing my mind 100 times. I eventually had him replace my entire roof. Tony did a fantastic job and looped me in the whole step of the way. He went above and beyond fixing bathroom vents that were not properly installed previously. He made it a priority to make sure all venting was proper so that my roof will last. I am so happy we went with Diconstanzo. I plan to use him for my gutters and siding in the near future as well. Thank you again!"
