Built-up roof (BUR) membranes have been in use for more than a century. They are also known as “tar and gravel” roofing system. Typically, in Built-Up roofing systems, asphalt or bitumen is applied between layers of roofing felts. Roofing felts are reinforced with organic or glass-fiber mats and are usually about 3 feet wide. Generally, coal tar, asphalt or cold applied adhesive are used as bitumen.
The cold adhesive is a solvent based asphalt and does not need to be heated to apply.
These multiple layers provide a very high resistance to water and extreme weather conditions such as wind, snow and hail.
