It is exceptionally long lasting! BUR owes its inherent longevity to the highly redundant nature of the system. With multiple layers of asphalt alternated with ply sheets, a BUR system achieves a uniquely layered and stable system to stop water intrusions. This redundancy also means a very high tolerance for foot traffic related to building maintenance. 

Asphaltic technologies have also evolved! The advent of polymer-modified asphalt products (PMAs) like our ENDURAflex SEBS have improved the overall performance capabilities of BUR systems. PMA's provide the waterproofing and weatherability of traditional asphalt with additional benefits like increased tensile strength, resistance to UV degradation, and remarkable elongation and elastic recovery. These enhanced self-healing properties make it possible to have a BUR system with a Class IV Hail Rating!

When performance characteristics are the determining factor in which type of commercial roof to install, BUR systems are the right choice. Think government installations, data centers, and medical facilities where the overall performance and long-term reliability of the roof is of the utmost importance. In fact, the U.S. government has concluded that BUR membranes are the preferred option for low-slope roofing applications for its buildings according to their Facilities Guidelines Specifications. 

We have many tools and informational resources to help you sell the benefits of BUR so please call, email, or reach out to your regional UA rep for more information.
