Modified bitumen is a type of membrane roofing that has evolved out of the development of asphalt roofing. Membrane roofing has grown in popularity in the last 40 years, phasing out traditional asphalt roofs in the process.
Besides the additional additives, membrane roofing differs from asphalt roofing in a variety of ways. Whereas traditional asphalt blends have to be weighed down with gravel or pitch, the rubber and other synthetic additives allow the modified bitumen roofing to attach itself to the base of the roof. In addition, it isn't as easily affected by sunlight as traditional asphalt roofing, which will be broken down by the sun's UV rays.
Modified bitumen is known for its near seamless application. This type of roof can be installed via either hot or cold applications, although the heating process is the most common method.
