Modified Bitumen Roofing Systems
Modified Bitumen roofing systems are one of the most time-tested roofing products on the market. It can be installed with one or multiple layers, depending on the roof’s substrate.
Modified Bitumen roofing systems are good heat reflectors because of the granules in the cap sheet. The granules are also a fire retardant. Modified systems should be installed on roofs with not less than ¼” slope in order to achieve positive drainage. When installed in single layers, a modified roof system has a 12-16 year lifespan. Multiple layers add to the life of the system. We offer many different warranties on our modified systems, including and up to 20-year no dollar limit warranties.
