"Bill Taylor, the President of the company, carefully surveyed the condition of the roof. His detailed, clear estimate addressed all of my concerns. The crew assigned to the project was efficient and courteous. The company is GAF certified, ensuring the warranty will be honored. I highly recommend Four Seasons Roofing."

"This was the best experience I have ever had dealing with a contractor. Jacob and his team went above and beyond my expectations. Jacob was able to stay within our budget. Cost that was estimated is what was invoiced at the end of the job. We started off with just getting our roof replaced but then decided to put a new roof and siding on our garage. Everything was done within two days. Left the outside of our house spotless. I recommend JI Roofing to everyone that needs to get their roof and or siding done."

"We have a two story home in Patchogue that had a leak that resulted in water in the walls of our attached garage. We could not locate the cause of the leak. We contacted Exterior Team Home Services who quickly located the source of the leak which required us to replace the front roofing of our house. It was done very quickly at a fair price. We were also impressed on how they made sure the old roofing material did not get into our front lawn or plants. They were meticulous in the way they treated our property. A job well done."

"Hector and Moises were excellent! Hector came with one other of their crew and assembled my permanent gazebo. I have stone pavers and they were very careful in cutting them and digging Deep enough to establish a good anchor. They even installed railings for my back stoop. I would highly recommend them! Clean... affordable and professional."

"When I needed a new roof, I called Jake. He handled everything from beginning to end. I received an estimate immediately, and a crew was on site in no time. The crew was neat, fast, and thorough. When they were done, you couldn't even tell someone was there...other than the amazing looking new roof! I highly recommend Jake and his team!"

FAQs for flat, foam, or single ply roofing installation and replacement projects in Port Jefferson, NY

Many roofing pros point to PVC as the top performer on flat roofs thanks to its tough seams and long-term waterproofing. A properly installed PVC membrane can last 30 years or more, resisting ponding water and harsh weather with ease. You will pay more up front than you would for EPDM, but the added durability often translates into fewer repairs and a lower cost per year of service.

Yes, a rubber roof is an environmentally friendly choice. Most rubber membranes contain recycled content and can reflect heat, which helps trim cooling bills in hot weather. Manufacturing has a lighter footprint than many traditional materials, and the long lifespan means fewer tear-offs headed to the landfill. If sustainability is a priority, ask your roofer about brands that carry third-party eco-certifications and confirm they meet local environmental standards.
