It is exceptionally long lasting! BUR owes its inherent longevity to the highly redundant nature of the system. Built-Up roofs incorporate multiple layers of asphalt alternated with ply sheets to achieve a uniquely rigid and stable surface with many layers of backup to stop water intrusions into the building. This redundancy also means a very high tolerance for foot traffic related to building maintenance. BUR systems are easy to repair and maintain; a universally desired trait for any roof.  Additionally, with the use of certain coatings that reduce thermal cycling, BUR lifecycles can be extended almost indefinitely.

It is Proven effective! BUR is time tested and field proven. The only way a technology can maintain such a lengthy stay in the realm of relevance is by being reliable, dependable and adaptable.  Just ask the U.S. government, who maintains one of the largest portfolios of commercial/industrial buildings in all climate zones. They have concluded that BUR membranes are still an excellent option for low-slope roofing applications for its buildings. Click here to read their findings.
