When we called to get an estimate George called back within 24 hrs. He promised the work would be completed in 7-10 days. They called on day 7 and started the job that day. The foreman of the crew explained they would protect belongings and thoroughly clean up which they did. The crew was professional, courteous, and showed enthusiasm about their work. Excellent job by George, Mike and the crew. Definitely will call GKG roofing if needed in the future.

GKG Roofing is the best. We have used them twice now and both times we had a fantastic experience. George is extremely knowledgeable, honest, and professional. Whether it is a big job or a small job, he takes the time to fit you into his schedule and does a great job. I would recommend GKG Roofing to anyone, and I plan to use them for all of my roofing needs!

GKG provided the most competitive estimate for our full roof replacement. Communication through the process was clear and honest and work was quality. Crew cleaned up after every day and a couple of understandable issues were addressed immediately and completely resolved within a couple of hours. Highly recommend George and GKG for your roofing needs.

George did a great job on fixing our roof leak. I would recommend him. He was prompt and worked us in prior to any more damage being done.
