Built Up Roofing

Built-up roofing is a highly popular multi-layered roofing system that performs well on both flat and low-sloped roofs. The layers consist of different felt/fiberglass sheets, and layers of asphalt. When applied properly, these roofing systems are waterproof. They are also known for their durability and ability to withstand harsh weather conditions. Built-up roofs typically are applied with anywhere from 3-5 plies (layers).
