What is the role of a "flashing" in BUR construction?

In BUR construction, flashing serves a critical function by directing water away from joints and edges. This is essential in preventing leaks, as these areas are typically more vulnerable to water intrusion. Flashing is installed at potential leak points such as where the roof meets a wall, around chimneys, vents, and in valleys. The material used for flashing is often made from metal or a flexible membrane, designed to withstand moisture and protect the integrity of the roofing system.

By effectively managing the flow of water and guiding it to appropriate drainage points, flashing helps ensure the longevity of the roof and reduces the likelihood of water damage to the underlying structures. This makes it a vital component of a reliable roofing system.
