Met three times prior to awarding the job to GKontos. They took the extra time to come back and ensure that the materials (including skylights) were exactly what we were looking for and replaced the current ones perfectly. Communication was superior with all members of their team. Roofing is not an inexpensive item, but GKontos was right on the same numbers as the other three quotes I had gotten.

Just had our roof replaced by GKontos. You often pay for what you get. We dealt with Angel and Bryce. Both were great to deal with and very responsive to our questions and addressed any issues that came up quickly.

From start, when they checked the roof both outside and in the attic, to finish, when the new roof was in place and the grounds entirely cleared of debris, the Kontos team was professional. Each person had their tasks to perform and did them well. I now have a new roof I need not worry about. And have already recommended GKontos to others!

We needed to redo our roof in order to install solar and this team did an amazing job. They also installed new gutters, downspouts and copper flashing around our chimneys. They didn’t all in one day!

Outstanding from start to finish with a great deal of attention paid to every detail.The amount of swift communication back and forth before the install date with my project manager John to iron out specifics about materials and prices was extraordinary. Definitely no rush job here nor any hint of "not having the time" for small questions. After the initial estimate, I decided to have them replace my soffits and fascia as well, and there were a number of possibilities and prices that needed to be gone over beforehand. John was always courteous and quick to answer, and very meticulous with details.The installation was great with the workers always taking the time to make sure that everything was exactly right. Precise cuts and alignments with all the fascia and soffits.And a shout out to location managers Bryce and Lorenzo - two more super-friendly and helpful additions to the GKontos staff.I could not be happier the level of service and end result. Highly recommended.

I recently had my roof replaced in LaGrange, NY by GKontos Roofing, and I couldn’t be happier with the entire experience. From start to finish, John Flister and Lorenzo were incredibly helpful. They took the time to walk me through the entire process, answered all of my questions, and even followed up to make sure I had everything I needed.On the day of the installation, the crew arrived promptly and worked with impressive efficiency and attention to detail. They stripped down the old roof and installed the new one all in the same day, which was remarkable. Most importantly, the cleanup was absolutely immaculate, you would never know a full roof replacement had taken place.A special shoutout to Lorenzo, who went above and beyond by sending me pictures throughout the day to keep me updated on each step of the process. This gave me total confidence and peace of mind.I highly recommend the team at GKontos Roofing for any roof replacement projects (10/10). Their professionalism, quality of work, and customer care are second to none. You will not be disappointed!

The sales team was extremely knowledgeable and explained all aspects of having my roof replaced. The crew arrived promptly and finished in one day. They were respectful and careful of my property and cleaned up very thoroughly. They were very professional and provided great service and value.
