What issue might arise if flashing is improperly installed in a BUR system?

When flashing is improperly installed in a Built-Up Roofing (BUR) system, one significant issue that may arise is an increased risk of leaks and water infiltration. Flashing serves as a crucial component in directing water away from potential entry points, such as joints, seams, and protrusions in the roof. If the flashing is not fitted correctly, it can create gaps or misalignments that allow water to penetrate beneath the roofing layers.

The failure of flashing to perform its intended function ultimately leads to moisture accumulation within the roofing system, which can cause serious damage over time, including structural degradation and mold growth. Proper installation of flashing is therefore vital to maintaining the integrity and longevity of a BUR system, safeguarding it against water-related issues. Recognizing the importance of correct flashing installation is essential for any roofing professional.
