Built Up Roofing

Built Up Roofing (BUR) Membranes are typically found on flat or nearly flat roofed buildings. These Membranes are referred to as built-up due to a process of overlapping several layers of roofing felts with hot or cold adhesives. BUR felts can be made of organic, fiberglass or polyester. The hot adhesives have three main types: asphalt, modified asphalt or coal tar pitch. The cold adhesives are either asphalt or coal tar pitch based. A layer of gravel is typically the final step, protecting the roof from ultraviolet degradation and providing weather resistance.

Advantages of BUR Membranes

  • Long track record that dates back to the early twentieth century
  • Can be cold or hot applied
  • High tensile strength reduces the possibility of roof splits
  • Excellent fire resistance
  • Excellent puncture and tear resistance
  • Multiple ply systems

Advantages of Coal Tar Pitch BUR Membranes

  • System can tolerate ponding water without risking damage to the membrane
  • Low melting point of the coal tar bitumen easily reseals small punctures giving coal tar pitch membranes a self-healing characteristic
  • System stays flexible for years after installation
  • Longest life system on the market

Advantages of Asphalt Based BUR Membranes

  • Low fuming characteristics of asphalt BUR is less objectionable to building occupants
  • High melting point of asphalt makes for a stable bitumen that will not run into the build or down the outside walls in hotter climates
  • Can be used on buildings with slopes over ¼” per foot without experiencing slippage of roofing felts
