    Don’t even bother with this company. All you’ll get are lies and empty promises. Met up with the owner. Asked him to come out and quote on replacing a skylight. He said no problem but I’d need to call the office to set up an appointment. During that call, the office manager said she couldn’t schedule an appointment but would pass along my phone number to the owner. After a couple weeks I called again. This time I was given the owner’s cell number. I called and told him of my previous conversation with the office manager. He promised to call on the following Wednesday morning to set up an appointment for later that same day. He did not keep his word. He did not call. That was an early warning sign for me. I have since moved on and I’m glad I did. A contractor who is that unprofessional, and unreliable, would surely have done a terrible job.

    I have built a few homes the past 7 years, Bosco Roofing is one of the best one out there. From small to bigger projects, polite and the service is the best! I strongly recommended.

    We recently had Bosco install our roof and were so impressed that we hired them for our board and batten siding. We are only half way complete but it looks amazing and the compliments are overwhelming. The crew really care about doing a great job. We cannot wait to see the final results.

    Our roof was just done a few days ago. It looks fantastic! The staff were very professional and extremely mindful of our koi pond. The clean up was quick and Brandon made sure to go over things again. Very impressed!

  • 5 out of 5Dave Beifuss7 years ago

    Courteous, professional, respectful and responsive all wrapped into a family operated business applying a superior product with a strong warranty, at competitive prices. Not sure what else I could ask for, in a roofing company.

  • 5 out of 5Angelo DiLettera8 years ago

    We hired Bosco Roofing to replace our roof and would highly recommend them. They came to the house, explained our options, and provided a reasonable quote. The work was completed in a timely manner, and any mess that was created was cleaned up before they left. We are very happy with the new roof and the service by Bosco Roofing.

    I wouldn't go anywhere else for my roofing needs. Bosco did a fantastic job on our roof, and our neighbors. The crew were very professional, and respectful individuals. The job was well done and done quickly. Overall a very pleasant experience.

    I hired Bosco Roofing to replace my roof. They came the day they stated and completed the job in a day. The cleanup was so good you wouldn't notice that the roof was replaced that day. I would recommend Bosco Roofing as a roofing …

    Rob at Bosco Roofing was great to work with! Great communication and price. The roof looks beautiful. Completed quickly and professionally. I tell all my friends that need roofing done that I highly recommend them.

  • 5 out of 5Linda Guerriero8 years ago

    I called Bosco Roofing to come and look my roof. I was fortunate enough to work with both Robert and Ricco. Robert came to my home to assess the problems we were having and gave me a quote and since my husband works days, I had to deal with this situation. I felt comfortable allowing Robert into my home while I was home alone with my 3 small children. Robert was respectful, reliable and trustworthy and I have to say on a personal note, he was so kind and loving to my children. I wanted Robert to give me a quote of replacing my entire roof and when he inspected the roof to assess the problem he told me that we didn't need a new roof that he would repair the problem and that my roof should still last me quite a few years. Robert could have told me that the whole roof needed to be replaced even though it didn't, he was honest enough not to take advantage of me. Bosco Roofing completed my roof in a timely and efficient manner, his crew came in early and fixed our roof. During the repair, I got to speak with Ricco who was their supervising and when we were speaking I mentioned that I heard a vibration near my daughters room, he immediately got on the ladder and went to look to see if he could see something. This was above and beyond, something he really didn't have to do and as it happened he saw something that he thought was the issue and he fixed it no questions asked. The Bosco crew fixed our roof, cleaned everything up and you wouldn't have even known that we had a crew on our property. We have recommended this company to our family and friends and will continue to do so.

    I don’t normally write reviews, but I think it’s important to share my experience. We are not talking about ‘oh my pizza was burnt- 1 star’. A new roof is costly and is an investment for your home. It’s a big deal! We purchased an older home, completely gutted it and renovated. We knew we had to redo the roof but were hoping it would give us a few more years, as we needed to ‘re-save’ for that purchase. We had seeked out many quotes, and this company was just a tad more expensive than some others but you get what you pay for. Rob explained everything, went over the warranty with us and they had 6 guys working on it and it was completely done in 1 day. They cleaned up so well that when I came home from work- the only reason I knew they were there was because my roof looked beautiful. I’m really happy! (Oh and another thing- when the owner Rob tells you he will be there at 6:00am. He means he will be knocking on your door at 5:59am, the most punctual contractor we had in the entire process of home flipping. His son is easy on the eyes too- so brush your teeth and put some lipgloss on! Hahah just kidding) Definitely recommend this company. Very happy! :)
