What is Kickout Flashing in architecture?

Kickout flashing is a crucial component in architecture, especially in areas where roofs intersect with walls. It is designed to redirect water away from the wall and prevent water damage, such as leaks and mold growth. Kickout flashing is typically installed at the bottom of a roof slope where it meets a vertical wall.

Importance of Kickout Flashing

Kickout flashing plays a vital role in protecting a building’s structure from water infiltration. Without proper kickout flashing, water can seep behind the siding and cause damage to the wall and interior of the building. By redirecting water away from the wall, kickout flashing helps maintain the integrity of the structure and prolong its lifespan.

Installation of Kickout Flashing

Proper installation of kickout flashing is essential to ensure its effectiveness. It should be integrated seamlessly with the roof and wall components to create a watertight seal. The kickout flashing should be sloped to direct water away from the wall and should be made of durable materials that can withstand exposure to the elements.

Types of Kickout Flashing

There are various types of kickout flashing available, including metal, vinyl, and PVC. Metal kickout flashing is commonly used for its durability and weather resistance. Vinyl kickout flashing is a more affordable option, while PVC kickout flashing is known for its flexibility and ease of installation.
