Modified Roofing Systems

    As a commercial roofing expert, one of the roofing solutions Rhino Roofing has available for your business is modified granular roofing.

    What is Modified Granular Roofing?

    Modified granular roofing is a membrane style commercial roofing system that has been used for over 50 years. It is constructed of asphalt and has plastic or rubber-based polymer binders to increase its durability. Modified granular roofing has a modified bitumen membrane. Sometimes hot asphalt can be used when sealing this material.

    Modified granular roofing can be installed in up to three plies, depending on the circumstances for installation. From here, membranes are welded together for increased durability.


    Modified granular roofing has been a tried and true commercial roofing solution that businesses have relied on for decades. This lightweight solution makes it cost effective as you can use less, all while getting more in the long-term.

    Because of the high heat used to help this type of roofing adhere to the surface, it helps to prevent leaks long term. When there are leaks in your commercial roofing, you run the risk of water damage and mold, as well as higher heating and cooling bills with air coming in from outdoors. By choosing modified granular roofing for your roof repair or replacement, you can count on long term coverage. In addition, it can stand up to inclement outdoor conditions, from hail and thunderstorms, to harsh winter storms. They can also stand up to fire as well.
