            19 North Mabbettsville Road , Millbrook, NY

            We agreed to 5400 to install a new shingle roof on the side of our mud room. The guys came. Did the job. Everything went well. We tipped them. One week later during rain we saw water on our windows. When we went outside we saw the roof wasn’t taking the water to the gutters but allowing the water to go between the wood and the gutter. I emailed them and am waiting for someone to come to look at the situation. I’m a bit frustrated to say the least. Let’s see how the situation is handled. I’ll keep you apprised. They had to fix the job 2 times but they did get it done. I’ve upgraded from 1 star to 4 for coming back and getting it right.

            They were very communicative throughout the process, and the install team worked a few long hard days to get things done right. We had one small hiccup during the project and I was satisfied when our main contact reached out to understand what happened and definitely made things right. Would definitely recommend anyone work with them.

            Let me start by saying that I am a Realtor and have access to a very extensive data base of contractors, and I chose GKontos to replace the roof on my home...they are by far the best and have truly earned their GAF Master Elite status!! George is thorough and runs an honest, top notch business. His project manager Alex is extremely knowledgeable and the entire crew worked tirelessly, from ensuring my home and grounds were protected during demo right through to the finished product...my gorgeous new roof!!! To find a company with talent, integrity and distinctive craftsmanship is impressive ....to add accessible, informative and genuinely caring...well that's GKontos Roofing!!!
