Built-Up & Modified Bitumen Roofing Systems

Built-up and modified bitumen roofing systems are very popular options for commercial buildings with flat or gently sloped roofs. Built-up roofing, often called BUR, has been used in some form for over a century in the United States. Mid-Atlantic Roofing Supply sources top brand built-up and modified bitumen roofing materials, supplies and accessories for any size commercial roofing project.

BUR systems have been popular for so long because of their excellent protection. The redundant layers of durable materials provide superior resistance and durability in all kinds of weather, protecting valuable buildings and structures everywhere. While built-up roofing systems require more time and effort to install, they are a preferred method of commercial roofing for many large construction projects.

Mid-Atlantic Roofing Supply can source your materials for any size BUR roofing project, from single businesses to large manufacturing centers. Not sure which option is best for your application (built-up or modified bitumen)? Ask a member of our team! The team at every branch of Mid-Atlantic Roofing Supply has the industry and product knowledge to help you make the best choices for commercial roofing solutions.

Top Brand Built-Up Commercial Roofing Materials & Supplies

Built-up roofing systems typically consist of a base sheet of material mechanically fastened to a layer of insulation. In the past, hot asphalt was used to adhere each layer of material together and form a waterproof seal; modern manufacturing has now introduced cold-application adhesives that are much easier and even better for waterproofing. Reinforcing felt layers create an additional barrier to water intrusion. This process is repeated until the desired level of layers is achieved. The entire system is then capped with a surfacing material or tiny gravel layer.

Modified bitumen is the newest form of a BUR system. It contains a mixture of asphalt and polymerized plastic or rubber that is reinforced with fiberglass. This forms an exceptionally strong and waterproof membrane for BUR layering. Both Built-Up and Modified Bitumen roof systems can be installed using an array of coatings and colors.

Mid-Atlantic Roofing Supply sources only the top brands of built-up and modified bitumen roofing products and supplies, including Johns Manville, GAF and Elevate. Contact the branch Mid-Atlantic Roofing Supply center near you and speak with a team member for product help or ordering assistance.
