Built-Up Roofing (Multiple Ply BUR or Combination BUR)
Total Roof Management specifies and brokers Built-Up Roof (BUR) systems utilizing key high performance components such as polyester roofing membranes and high-penetration index asphalt. TRM also specifies combination BURs that blend multiple plies of traditional fiberglass felt with thermoplastic membranes, which are typically associated with single ply roof systems. Surfacing options for each BUR system can vary with requirements for fire safety, environmental & energy efficiency codes and the wishes of the building owner. The achievable goal in each BUR design is to create a roof membrane with multiple plies of waterproofing protection (redundancy) combined with superior strength (through saturation), elastomeric properties (for elongation) and high solar reflectivity (emissivity thermal values.) All roof systems recommended and specified by TRM have “in service” performance records that are longer than the typically desired warranty periods, have an absolute ZERO history of failure or problems and can be fully guaranteed for various lengths of time.
