Diverting flashing is specifically designed to redirect water away from areas that are prone to infiltration, particularly at roof and wall intersections. In this location, it effectively channels water that may flow down a wall and prevents it from entering the building through the junction between the roof and the wall. This is crucial for maintaining the integrity of the structure, as water intrusion can lead to serious issues such as mold, structural damage, and deterioration of building materials.

While diverting flashing can play roles in various parts of construction, its primary function is most effectively employed at the end of a roof and wall intersection. The other locations mentioned, such as windows or foundation bases, typically utilize different types of flashing or moisture control techniques tailored to their specific needs.
