What Is A Built-Up Roofing System?


Built-up Roofing System (BUR), also known as tar and gravel roofing, is a flat or low-sloping roof constructed by alternating bitumen layers (asphalt or coal tar) and reinforcing fabrics, such as fiberglass or organic felts. These layers are then reinforced and topped with a layer of gravel or a mineral cap sheet to provide protection from weathering and physical damage.


BUR systems are very effective in many different geographic areas and climates, especially in extreme temperatures and weather conditions. They are known for their durability and longevity, with some BUR systems lasting up to 30 years or more.

Components Of A Built-Up Roof System

A black, tar-like substance made from either asphalt or coal tar that is used to waterproof the roof.

Reinforcing layers of fabric that are used to provide structure and strength to the roof.

A layer of material that is used to provide thermal insulation and energy efficiency to the roof.

Strips of metal or other materials that are used to seal the edges and seams of the roof to prevent water from penetrating.

A layer of gravel or a mineral cap sheet that is used to protect the roof from weathering and physical damage.

Elevate Your BUR System

To elevate the performance of a BUR system, there are high-performance ply sheets made from fiberglass or organic felts that have been saturated and coated with asphalt for greater strength and durability. Another option may be reflective surfacing options that improve the energy efficiency of the roof by reflecting sunlight and reducing heat absorption.
