What is a Modified Bitumen Roof?
A modified bitumen roof utilizes hydrocarbon materials or bitumen, a classic building material based on petroleum products. Industry resources show that this type of roof material has been used in the U.S. since the 1970s with positive results. Modified bitumen, or MB, is commonly referred to as asphalt or tar. It gets combined with rubberized polymers or otherwise refined to create roofing materials that offer several key benefits, especially on lower slope or flat roof structures.
Benefits of Modified Bitumen Roofing
Experts claim that modified bitumen roofing provides high tensile strength and reduced brittleness. Competitive life-cycle cost is another plus for this kind of roofing. Low VOC application methods are generally available, which is important when volatile chemicals can threaten the health of residents by lowering indoor or outdoor air quality. MB can also offer greater flow resistance at high temperatures.
Installing MB Roofing
Modified bitumen roofing can be installed using a “torch application” method. It can also be applied in a “cold process” with adhesives or with a process called “hot mopping.” Diverse application choices also make modified bitumen a popular choice for roofing material.
Builders can explain more about the various options available in using MB in conjunction with other modern roofing materials.
