A built-up roof (BUR) is a system of roofing that is made up of two or more layers of material such as asphalt, tar paper, and felt. This type of roof can provide protection against heavy rainfall and high winds.
Many homes and buildings have a roof that is made up of multiple layers, which helps to keep them weather-proof. The more layers there are, the more protection the home has from rain and snow. However, the amount of protection the roof offers will depend on how many layers it has. Built-up roofs can be constructed in a few different ways, depending on the needs of the the building.

Why Choose
A BUILT-UP (BUR) ROOFING SYSTEM?
The two common types of built-up (BUR or modified bitumen used in commercial, flat or low-sloped roofing systems are Atactic Polypropylene (APP) and Styrene-butadiene-styrene (SBS).
Atactic Polypropylene (APP) is a thermoplastic modification that contains either polyester or fiberglass mat. Theses membranes provide insulation against hot and cold climates.
Styrene-butadiene-styrene (SBS) is a premium modified bitumen made out of asphalt and synthetic rubber. The membranes are engineered specifically for elasticity making it an exceptionally flexible material for flat roofs.
Both APP and SBS systems are extremely durable, low maintenance and increase the longevity of your roof.
