"G. Cannon Roofing and Siding replaced my roof, siding, and gutters this summer and did a great job! They explained my options up front to help me choose what was best for my home. They were courteous, efficient, professional, and they kept in communication with me throughout the process, which I greatly appreciated. My home looks great and I am grateful for their efforts to make my home a nice, safe place to live. I would highly recommend them to my friends and family. Thank you!!! I'll provide photos soon. Kevin M. (Newtown Square)"
"We had a fantastic experience with them (they redid our entire roof). Not only was their quote very competitive, but the job and subsequent follow up was handled to our perfect satisfaction. Our expectations have been exceeded in every way."
"If you want a perfectly done roof with a long warranty at a low price use these guys. Of roofing, these guys are that pizza place where for a dollar you can buy a giant slice that tastes just perfect and you are not quite sure how the economics of that work out on there end but you are afraid to ask."
