"Presidential Exteriors is a great company to do a roof replacement with! We had our roof replaced in early February 2021 and we couldn’t be happier. The whole team was amazing to work with. Nate worked closely with us every step of the way to make sure we were happy and getting the best product and prices possible. He really made us feel like family. Elena was great at communicating every step of the process. The day of installation team was amazing. They dropped off the equipment one day before the project even though it had snowed the night before. The morning they came to do the roof, we still had ice on the roof, but instead of delaying the project, they scraped all of the ice off our roof and still got the whole roof done in one day! Our new roof is great and we couldn’t be happier. We very highly recommend Presidential Exteriors for any roof inspection and roof replacement. We will absolutely be keeping them on our list for any future projects with our house."

"I’m going to begin this review by saying, I have never hired someone to do a job on my house where I have been completely satisfied with the labor and the finished product. Until now. I just hired a company to remove my existing shingle roof and replace it. Not only is the finished product of excellent quality, but the technicians were extremely diligent in making sure everything was done with precision. The entire job even down to the clean up afterwards is outstanding…. I highly recommend Coxs Roofing and I will be using them whenever I need roofing work done. Oh! And they also had the best price quote out of three estimates I received. 1121 Roland Heights Ave. 21211"

"I like Dean alot, he is personable and professional. He gave a decent price, showed up on time. He promised an additional warranty if I got the roof coated, which I did. At the time of applying the coating we discovered a problem with the original install which me promised to return and install a small gutter to repair the problem. He has not return and has not responded to my text. In trying to work with Dean's staff to fix this problem and Michele was extremely rude to me and called me demanding."

"Isaac came out for an estimate and quickly diagnosed the issue. I hired him on the spot for the repair, which was completed same day (within 30 minutes). Will definitely reach out to Edward Kelbie for future roofing/gutter needs."

"Estimator came out with a drone to look at condition of the roof. Gave us 3 different options for roof replacement. We choose the middle price option. Big crew came out and did the work quickly and neatly. The price they quoted us was half of what other contractor wanted."
