Elements of Built Up Roof Systems

Built-up roofing is also often called “tar and gravel” in the roofing industry. This is due to the use of layers of bitumen in the makeup of BUR. Bitumen is a black material (earning its nickname of “tar”) that is often derived from a natural source or from residue. Bitumen, in simple terms, is usually made from coal tar, cold-applied adhesive, or asphalt.

Built-up roofing or BURs is one of many roofing systems that are most commonly used. They are made up of multiple layers of bitumen that serve as the base sheet which is layered on top of each other, with the top layer often being made of gravel, concrete or crushed rocks which is then covered with aluminum coating or rubber polymer coating.

 A fully adhered BUR will be one that has been laid directly to a roof deck. The last element found in built-up roof is the ply sheet, often known as the roofing felts. This reinforced fabric serves as one of the layers in the BUR that is reinforced with glass-fiber or organic mat. The protective layer reinforcement repels water while still allowing the material to breathe.

Other elements that you can find in BUR commercial buildings systems include:

  • Asphalt
  • Cover board
  • Deck
  • Cap sheet which can be
  • Rigid roof insulation

And the actual layering system will often go deck, roof insulation, asphalt, cover board, asphalt, ply sheet, and so on. For surfacing, manufacturers use different types of materials: aggregates, fiberglass or mineral surfaced cap sheets, hot asphalt, aluminum coatings, or elastomeric coatings. The first layer can be adhered directly to the roof substrate. When installing the BUR, if the modified bitumen is made of hot asphalt or coal tar, which is heated up in a tanker and then applied by mop or mechanical spreader. A multi-ply smooth surface BUR system can be restored by resurfacing a flood coat of asphalt, a fibered aluminum roof coating, a white or pigmented elastomeric roof coating, and/or asphalt coating and gravel. 

For the very final layer of the built-up roof, a mineral surfaced cap sheet, glass-fibers, or rock aggregates will be spread. A finishing ply will then be applied to seal off the cap sheet.

  • Conduction resistance: Roofs made of a BUR system have excellent conduction resistance, which lower costs in your heating and cooling bills.
  • Multi-layers: Multi-layers found in a BUR system (between the cap sheets that make up the system) give your roof years and years of consistent and reliable protection.

Built-Up Roofing Vs. Single-Ply Roofing

Typically, a modern flat method employs single-ply roofing (also known as TPO roofing) that is chemically bonded and thus creating a strong layer of protection against seeping water. These roof membranes are designed to reflect UV rays. Built-up roofing delivers superior waterproofing and reliability, with finishing options that add UV resistance.

While single-ply roofing has lower upfront costs compared to built-up roofing, it costs much higher with ongoing maintenance and maybe much more vulnerable to UV rays.
