Bituminous Roofing Systems
Bituminous roofing systems utilize bitumen, a resilient mixture derived from crude oil. This versatile roofing material is applied in various forms to create durable and weather-resistant membranes suitable for a wide range of commercial applications.
Built-Up Roofing (BUR):
​
-
Description: BUR, often known as "tar and gravel" roofing, consists of multiple layers of bitumen alternated with reinforcing layers of roofing felts (typically fiberglass or organic felts). The final layer may include a surface coating of gravel or mineral granules for protection against UV rays.
​
-
Application: Layers are applied using hot asphalt or cold adhesive, and the roof is built up to create a durable, multi-layered system.
​
-
Advantages: BUR systems are known for their longevity, fire resistance, and waterproofing capabilities. They are suitable for flat or low-slope roofs.
