At first I was extremely upset that the “builder grade” shingles on my 10 yr old home in West Chester were damaged beyond repair causing a leak. I wish the builder used a more quality product.

But Matt Parker and his team at Core did an outstanding job from beginning to end. The process went smoothly. Communication before and during installation was handled well. The installation crew looked as professional as they can dress while working on a roof all day. They also did great job including site clean up. Quality job all the way around. I am extremely happy with the quality of my Owens Corning roofing system.
