Counter flashing is also known as what?

1. Cap flashing

2. Base flashing

3. Step flashing

4. Fascia flashing

The correct answer is: Cap flashing

Counter flashing is commonly referred to as cap flashing. This type of flashing is typically installed at the junction where a wall meets a roof, particularly at chimneys or vertical walls. Its primary purpose is to direct water away from the wall and prevent it from seeping behind the siding or the roofing materials. Counter flashing works in conjunction with other types of flashing, such as step flashing, which is used along sloped roofs to create a barrier against water. Cap flashing specifically is positioned over the step flashing, creating a single continuous barrier that enhances the protection of the area. This is important because roof leaks can lead to significant water damage if not properly managed, and understanding the role of cap flashing in the overall flashing system is crucial for any home inspector. Other mentioned types of flashing have distinct functions; for example, base flashing is often installed at the lower edge of a wall, and fascia flashing relates to the edges of the roofline, further distinguishing the specific application and function of cap flashing in roofing systems.
