"A previous roofer could not stop the leaks coming from one of our skylights. Dan from Central Exteriors did an excellent job diagnosing the problem and fixing it. I highly recommend Dan and Central Exteriors for your roofing needs."

"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."

"We had a roof leak and Amazing Skylights made quick work of it. They were very helpful and responsive and saved us from further water damage. It's been six months and no recurring issues. We had a great experience with them."

"When I called the company, they came to my house within 30 minutes to do an estimate because I told them I had open holes in my roof. Ben came and made me feel confident in his abilities to assess the roof and recommend the best roof for me. The workmen came and put the roof on quickly and meticulously cleaned up after themselves. A snow storm was predicted in 2 days, and another man from the company came before the snow to check and be sure everything was taken care of and solid. They also installed a ridge vent. I highly recommend this comapny. My roof is beautiful and definitely adds value to my home."
