Modified Roofing System on a Commercial Flat Roof

What is Modified Granular Roofing?

Modified granular roofing is a type of commercial roofing system that features a membrane-style construction and has been used in the roofing industry for more than 50 years. At Rhino Roofing, our roofing team offers exceptional quality modified bituminous membrane roofing solutions for commercial customers in Colorado, Wyoming, and South Dakota.

Features and Benefits of Modified Granular Roofing

This type of roofing system consists of asphalt combined with rubber or plastic-based polymer binders that improve its durability. Modified granular roofing features a modified bitumen membrane. In some cases, this modified roofing system may be sealed using hot asphalt.

Modified granular roofing holds up well when subjected to inclement weather conditions, including severe winter storms, hail, and thunderstorms. It also provides significant resistance against fire. With proper care, the modified granular roofing material provides a service life of 15 to 20 years. It features a smooth coating that is visually appealing.

Our Modified Bituminous Membrane Roofing Installation and Repair Services

The installation process we employ for modified bituminous membrane roofing can consists of up to three plies, depending on the nature of the installation. We then weld the membranes together, which increases the durability of the roofing. In addition to asphalt, granules are added to the membrane roofing, giving it increased protection against UV rays and heat from high temperatures.

Our roofing professionals can also provide repair services for modified granular roofing systems to restore certain areas of your roof back to optimum condition.
