Commonly referred to as “tar and gravel” roofs or by the acronym BUR, built-up roof membranes have been the most popular material used on low-slope roofs in the U.S. for over 100 years.
Multiple layers of bitumen (asphalt or tar pitch) surfaces called ply sheets, provide excellent water and fire protection. Sheets are commonly reinforced with organic or fiberglass mats, depending on their application. Surfacing materials are coated with reflective material or paint to provide UV protection. They offer excellent thermal insulation, and can greatly reduce building heating and cooling costs for your business.
Built-up roofs are easy to repair and tend to be low maintenance, making them a versatile, affordable option over the life of the roof. With a long history as the preferred choice for commercial buildings, built-up roofs are constructed using durable materials and even stand up to heavy foot traffic when necessary.
