For low-slope or flat roofing, modified bitumen is one of the best choices available on the market today. Roofing companies regularly install these types of roofs for commercial properties because they are known for their longevity and resilience under intense weather conditions. Bitumen is commonly used in built-up roofing, or BUR, systems.
Modified bitumen is an improved roofing material that combines the benefits of built-up roofing, bitumen, and polymer or rubber characteristics. By blending bitumen with a polymer or rubberized compound, the asphalt itself then takes on some of the characteristics of these compounds. Roofs constructed of modified bitumen have all the benefits of BUR roofs in addition to added tensile strength.
Benefits of Modified Bitumen
The additives that make BUR roofing into modified bitumen roofing increase its resiliency and puncture resistance. The typical bitumen membrane is further waterproofed and improved, thereby increasing the size and coverage area of the plies, or sheets of bitumen roofing. This makes installation easier and provides a quality seal against the elements for low-slope and flat roofing applications.
Modified bitumen roof systems are constructed to exacting specifications; when quality materials, such as those from GAF, are installed by an experienced roofing company, your roof will stand the test of time. Because most of these systems are manufactured with rigorous standards, the end result is increased uniformity and high quality.
Modified bitumen roofing systems consist of several layers that improve the thermal performance of a building, making it more energy-efficient and protecting it from the elements.
