What is BUR?

Built-Up Roofing (BUR – “tar and gravel” – coal tar - asphalt and gravel) is the most classic “tar and gravel” system of roofing. Traditionally flat roofs have been installed by setting three - four layers of coal tar with coal tar saturated felts (tar-paper). Typically, the surfacing is gravel set in a flood-coat of hot asphalt. Coal tar is a by-product of the coal manufacturing process and makes an excellent water and oil resistant material. An unusual feature of a coal tar roof is its’ ability to soften in warm temperatures and "heal" itself. The warmer the temperature the faster and easier the membrane adjusts to changing conditions sealing minor ruptures and abrasions helping to keep it young.

However, tar and gravel flat roofing systems have a long service period if it is well maintained and repaired.

It is always important to consider your location in the world when choosing a roof because of important factors like ultra violet rays. An asphalt and gravel roof can be adversely affected by ultra violet rays and will not maintain its integrity if water is ponding on top of it because it is moisture resistant rather than moisture proof.
