Callahan Builders LLC/ Glen Rock Roofing

We had roof and gutter replacement with Mark. Mark and his team are the most reasonable, reliable and trustworthy one can find. Mark listen to customers requirements and take care of it with reasonable price. Mark and team take pride in their craftsmanship with solid work done. Once I have any concern or concerns. He shows up right away(even on a chilly Black Friday!) to explain to me and do everything to make us feeling comfortable. And a lot of us local people honestly highly recommend him and his team!

I have had several jobs completed by Callahan Construction over the years and am very happy with the work & service. The owner is very personable and takes ownership of his projects. Highly recommended!
