I have had roofing problems with my home from the day it was built. Prior to contacting RJK, my home underwent 2 complete tear-offs with new shingles installed. I do my homework and only have work done by companies that are rated excellent by various rating agencies. My roof still leaked. My 3rd tear-off was performed by RJK Construction Co. The job by RJK was very intensive. I had a complete tear-off, 75% of underlying sheathing replaced, attic insulation replaced, 3 skylights replaced, and ventilation issues corrected. 4 years later, absolutely NO leaks. RJK by far is the best roofing contractor in Ohio. The Sales Manager, Mr. Greg Pike, was always on time with all appointments. Greg also returned phone calls and e-mails quickly. Mr. Ron Kirkland was also available whenever I needed some questions answered along with providing ideas for aesthetics. The crew members were very knowledgable and courteous at all times. RJK also replaced my gutters, 2 windows, and porch screening.
