Modified Bitumen Roofing

Modified bitumen roofing is one of the most popular options for roofing systems. It consists of asphalt, reinforced with polyester or fiberglass and then topped with either a granular or smooth surface. This type of roof is made up of multiple layers, which provides strength, durability and superior waterproofing properties to protect from water, temperature fluctuations and damaging weather conditions. It is also a highly-reflective, which helps to conserve energy and keep the costs of cooling and heating a building low. Modified bitumen roofing demonstrates the qualities of a built-up roof system, but with the ease of a single-ply system application as well as easy repair.
