Flat Roof Installers in Port Jefferson, NY

"100% satisfied. Sami contacted me immediately, came out on a weekend to quote, and finished job a few days later. He's a very honest guy who takes pride in his work, and i'd highly recommend."

"We had gutter covers installed. Onyx staff answered all our questions and were great with communicating to us by text when weather changes required rescheduling. They were prompt and professional. Highly recommended."

"Tony is great guy! Hard working , professional, courteous. He replaced our skylight right away for us. He was on time. Very neat and cleaned up everything. I would definitely recommend him and rehire him other projects. He is our go to guy!"

"Great Work / Fair Price & Great Delivery. Ed and the team at O'Brien Brothers would definitely be a strong recommendation."

"It was a great experience hiring Nick and his helper Edward who were on time , extremely courteous, and professional. In this day and age it was a pleasure to hire someone who is straight forward, honest, and kept his word. Nick did an outstanding job explaining the details of what work was needed to be performed and why during his initial visit to quote the job and took me on the roof to show me why. During the repair of the roof he took time to show me exactly what was being done and why and most importantly where the water damage was coming from as he initially thought when he quoted the job. In addition to doing an excellent job with the repair of the roof Nick and Edward did a spotless cleanup. Nick's price was better than 4 other quotes I received which none of them went into the degree of detail of Nick's quote. The other 4 quotes from the other contractors were either the spot fix short and easy way or expensive way highlighting that I would have to replace my skylight to warranty their work. I highly recommend Nick and would be happy to answer anyone's questions about the job he performed."

"Great guy. Great work"
