Typical built up roofs consist of three main components: cap sheet, ply sheets, and bitumen. The ply sheets act as ‘glue’ between the layers. Bitumen is applied in two different ways: hot and cold. Hot bitumen liquefies during installation, while cold bitumen is applied without being heated. Hot bitumen tends to produce harmful fumes, while cold bitumen does not.
A built-up roof can weigh anywhere from 2.5 pounds per square foot on a smooth surface to as much as 6.5 pounds per square foot on a gravel surface.

This is why hiring a roofing contractor is the safest way to install a built-up roof.
