  Beware they will not honor their warranty. When they first finished the job we thought it was fine. 6 months later we’ve had two leaks. The first one they fixed after weeks of backs and forth emails and no shows. They second leak is much larger. After another no show they came and agreed it needed to be fixed but became downright hostile when asked to commit to a time frame for fixing it. Now it’s three months later and not a word from them. We’ve had to hire another company to fix their mistakes. Look elsewhere if you want a company that honors their warranty and treats customers with respect. Edit: they have never reached out again.

  Hi Rae, this is John Cannizzo. Again I apologize for any inconvenience this may have caused. Unfortunately I do not have your information because I believe Dan my brother who is no longer with the company was handling your project. Can you please reach out to us so we can try to make it right? 973-513-2992

  PLEASE READ BEFORE YOU CHOOSE. I wish I could explain just how awful I feel about wasting my money(3000 dollars) and time not to mention the aggravations I experienced. We hired them for a simple leakage of roof. Dan came with one other guy, gave me a rosy explanation what is the problem. I believed him and paid 300 as downpayment. He sent 2 guys to work few hours to replace 1 skylight( cheaper looking one than what we originally had) and 3 feet of shingles around the light. He said that's all we needed plus the valley area. I honestly took his words and paid him the rest of the money. Then came a big rain storm that weekend. My roof and ceiling leaked so much worst than before, I was so shocked. Words do not explain like pictures do. I called Dan, he said he is sorry and he will fix it. Couple days after, he sent someone to fix it. Supposedly he did but said not to repair the damage inside yet. I didn't know why back than but I understand now. He was not confident with the fix. Few days after that another rain storm came down and the same spot leaked again. Areas of skylight but this time the inside underneath the sky light as well. I called Dan, he said he may have misdiagnosed the problem. But he states we have to pay more and fix the entire area. Remember, so far, I paid 3000. According to another roofer, that whole section could have been redone with 4000 plus the cost of the window. Dan said he can not fix it since he is done with it. He wants more money to fix the original problem I hired him for. He also sends subcontractors with different license number and names on the van. I don't think he owns two or more companies. The guy he sent the second time didn't even know Dan's name when I asked. I took pictures of everything including the different van with different names of the contractor. I am in the process of getting another roofer and having to repair what his guys did. I kept all the records of our text conversations, before and aft

  This was a big mistake that we have learned a great deal from. I apologize from the bottom of my heart. Dan is no longer with the company. So this will never happen again. I wish I could have handled this before it had gotten to this point, John Cannizzo - Owner.

  John and his team are great. The quote is done on the same day, and the work is completed in a couple of days; it is an excellent job every time. They even make sure every nail is picked up off the ground after they are done as part of the cleanup. We at Keyrenter residential property management bring in Roofshark every time a client needs a repair or a new roof. You should too!
