I had roof work done in 2013. No problems at all. They send someone out to do a free inspection every year for 10 years and apply caulk or a screw etc. wherever needed for free. I picked quality CertainTeed shingles and Grace ice and water shield along with new gutters and everything was installed correctly. I saved money compared to other quotes too. I am satisfied.

I am very pleased with how well our project went. The installation of our new roof was seamless, and the communication from our Project manager kept us informed as to what to expect. Tri-County also fixed some issues we had with our old gutter flashing, and removed our Chimney to below our roof line, which we did not need any more .

I called a lot of places to get quotes and they were the only one that didn't harrass about in person quote - This was about 5 years ago I had them come out. They had the best price. They came out and worked quickly and got it all done in a day - tear off, replace boards, and new shingles with a great warranty. They come out every year and call when they are coming out. Very happy with their service. They answer the phone.
