Customer Reviews

"We are very pleased with the entire project. Our project manager, Mario, guided the project impeccably, from start to finish, and everything was completed in a very timely manner. If we had questions, Mario was always on site and could answer them with a detailed explanation. The crew took their time to make sure every detail was complete and their work area was cleaned up as if they had never been there. They replaced our roof, wrapped our soffits and installed new gutters. We are very pleased to have chosen Trenton Roofing & Siding and would not hesitate to use them again on future projects. We highly recommend them - they are a class act."
"We had a fantastic experience with Brian Fallon and the entire Trenton Roofing team. Right from the first contact to the final close-out it was an outstanding experience. Even on the day of installation the crew came on time and actually finished a few hours earlier. I will have no hesitation in recommending them. It was a real pleasure to do business with Trenton Roofing."
"I had a very positive experience with Trenton Roofing and Siding replacing my roof. Our Project Manager Brian was responsive, professional, knowledgeable and very detailed. When it came time for the work, the job/process was performed exactly as Brian had described. They also took care to protect important items. The roof looks great and they did a fantastic job cleaning up. I certainly recommend Trenton Roofing and Siding."
