What is another term for cap flashing?

1. Base flashing

2. Counter flashing

3. Dormer flashing

4. Wall flashing

The correct answer is: Counter flashing

Cap flashing refers to the type of flashing that is installed at the top of a wall or vertical penetration like a chimney. Its primary purpose is to direct water away from the joint where a roof meets a vertical surface, preventing water intrusion. Counter flashing, which is the correct term in this context, is specifically designed to overlap other types of flashing, such as base flashing. This overlap allows for effective water management by creating a barrier that diverts water away from critical areas, enhancing the overall waterproofing strategy. In contrast, base flashing is typically found at the base of walls or protrusions and serves a different function. Dormer flashing relates specifically to dormer windows and is intended to manage water around that architectural feature. Wall flashing, while also a component of weatherproofing systems, focuses on directing water along a wall surface but does not have the same function as cap flashing. Counter flashing stands out because of its specific role in protecting the integrity of joints and terminations in roofing systems.
