George was so professional and great to work with. He repaired some roof leaks that other companies were not able to find and was the roofing company we went to when we needed a new roof after storm damage. Highly recommend GKG roofing due to their reliability and quality work done!

I am satisfied with my new roof. George Gilliland, the owner was courteous and informative. After George checked my roof, he covered it with a piece of tarp to prevent any more damage which I was thankful for because it rained the next day. His crew arrived early the day of the project and started working immediately. The crew was very professional with excellent service. The new roof was completed in a day. The area around my home was totally cleaned up. I absolutely love the finished product. ... Read more

He discovered that the attic fans that we had installed years before had been installed improperly and had been leaking and had rotted much of the wood. All the other patch work repairs that were suggested by the other companies would not have taken care of my problem. My ... Read more

GKG Roofing is hands down the best roofer we've every worked with. George tackled a huge problem with our leaking roof (and by leaking, I mean we had an indoor water feature it was THAT bad) on our room addition which a previous roofer had incorrectly installed. He knew immediately how to remedy the situation and quoted a fair, honest price. His crew arrived on time and went right to work. They were meticulous and diligent with every facet of the installation. George was onsite and oversaw all... Read more
