What type of flashing prevents water intrusion at changes in direction and between different materials?

Wall flashing is specifically designed to prevent water intrusion at changes in direction and between different materials within a building's exterior. It acts as a barrier, directing water away from vulnerable areas where materials intersect, such as where siding meets the foundation or windows. Proper installation of wall flashing is crucial because it helps avoid moisture accumulation, which could lead to structural damage or mold growth.

Kick-out flashing, termination flashing, and drip edge flashing each have distinct functions and are utilized in more specific applications. Kick-out flashing is primarily used to direct water away from the intersection of roof planes and walls, while termination flashing is applied at the top edge or where a waterproof membrane ends. Drip edge flashing is found along the roof edges to facilitate water runoff, ensuring that it flows into gutters rather than seeping underneath shingles. Understanding the unique roles of each type of flashing helps in selecting the appropriate materials for effective waterproofing in construction.
