Customer Reviews

"GKontos came highly recommended, and they didn't disappoint. They were attentive in giving me an estimate, took care of all of the permits quickly, and did the job in a day. I had a leaking flat roof caused by bad flashing and a whole mess of other shoddy workmanship by whoever did my original roof. The repairs that GKontos did involved replacing the flat roof, and tearing up a portion of my pitched shingle roof to join the two properly. They matched my existing roof shingles perfectly in terms of color and did an outstanding job reshingling and fixing some other flashing problems around my chimneys. The new flat roof looks infinitely better than the last one. I would use GKontos again 100% for another roof repair, and recommend them in a heartbeat."
"My gutter guys noticed a small crack in my rubber roof and recommended GKontos. I was afraid we couldn't get it attended to as winter had already set in. But GKontos came in two days, fixed that crack and a few other small ones they noticed. They were polite, professional, knowledgable and quick. I will use them again as soon as my roof needs replaced."
"GKontos did a fantastic job, they are very responsive, they took care of work that wasn't even their responsibility. They warranty their work to the highest level. I will recommend them to everyone, and I'll absolutely use them in the future. They deserve the highest possible review!!!"
