  • "They offer the highest quality roofing service from start to finish, and at affordable prices."

    - J.C, Jun 4, 2022

  • "Kevin is a great salesman AND customer service rep. We had our roof done back in 2019 and couldn't be happier. From the start, he was on-time, answered all of our questions, and gave us a great price for a new roof on our home in King of Prussia. Any questions we had, Kevin responded quickly and took our call right away. He was here off-and-on to manage the job and knocked on our door at the end of the work day on both days to let us know they were leaving. What was most impressive was that he made sure our lawn was clean and free of debris at the end of the day (even though they were coming back to finish the next morning). It didn't really matter to me, but it made my wife happy. The G. Cannon workers were friendly and professional throughout the entire installation. Most importantly, they were quick. We both work from home so we were hoping it wouldn’t take them an entire week to finish the roof like other companies had quoted. Instead, G.Cannon actually finished our entire new roof in a day and a half. Kevin sold us on a lifetime warranty for our roof — which I can’t imagine companies would want to give out unless they are truly confident in the quality of their workmanship and materials. Our roof had leaked several times over the last twenty years and no roofer could ever find the problem. It’s now been about three years since G. Cannon Roofing installed the new roof on our home and we haven’t had ANY leaks. Seriously, ZERO. I was thinking about this the other day and it prompted me to write this review. If you’re reading this because you're looking for a roofer you can trust for quality work at a fair price, just call these guys."

  • "Great job on our roof! Experience from start to finish was top notch and cleanup was superb. Would definitely use them again! Thank you!"

  • "Great owner, very professional and prompt."

    - J.S.

  • "The customer service rep was very quick to respond and schedule a free estimate. They had the lowest price of the three roofers in King of Prussia that we contacted. Unlike the other two companies, the estimator from GCannon showed up when he said he would and explained the process in terms I could understand. I really can't overstate how important and helpful this was for someone like me who is not at all knowledgable about roofing or most home repair projects. Most importantly, they found and stopped the leak we were having when other's were unable. Thank you again!"

    - W.W.

  • "Kevin is a good salesman but lousy customer service rep. He did not really supervise installation. The company outsourced the job to a crew from NJ. I live in western Philly suburbs. On our flat roof, the edges of the asphalt sheets installed came off after a few days. They did send the NJ crew to apply gobs of tar later. There was a leak around the skylight after the first big storm. They did send the NJ crew to "fix" it. There were 2 other leaks which were not there a year ago. These may not be this roofer's problem but Kevin has been angry, confrontational, and blaming other contractors. Yes, I have a 5-year warranty on my roof. I would prefer confidence that i have a good, sturdy roof. I do not have confidence in this company."

    - S.D.

  • "I made an appointment for an estimate but no one showed. When I called they said the person scheduled was not in on that day. How come no one took that persons appointments or even called to let me know after I waited for them. How can a business make money this way?"

    - L.G.

  • "Great job on our roof! Ty guys. Experience from start to finish was top notch."

    - C.G.

  • "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)"

    - K.M.

  • "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."

    - S.C.

  • "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."

    - M.C.

  • "Kevin is an excellent roof inspector, very honest"

    - J.S.

  • "Seamless experience from start to finish. Excellent work and great customer service. Our roof looks better than expected! Will absolutely recommend to anyone. Thanks again"
