Homeowners and building owners should know about “kick-out” flashings because they prevent water from seeping behind walls, protecting against rot, mold and very costly structural damage. Proper installation of this component is critical and can save you $$$$$$$$.

Why are Kick-out flashings important?

1. Prevents Water Intrusion at Roof-to-Wall Intersections

Kickout flashing is installed where a sloped roof ends and meets a vertical wall (often near chimneys or sidewalls). This flashing directs water away from the wall and into the gutter system. Without it, water can run behind the exterior cladding and seep into the wall cavity, leading to rot, mold, and structural damage.

2. Protects Building Envelope

Properly installed kickout flashing helps maintain the integrity of the building envelope by preventing moisture infiltration, which is a leading cause of building material deterioration.

3. Avoids Expensive Repairs

Neglecting kickout flashing can result in long-term water damage that often goes unnoticed until it becomes a major issue, potentially costing thousands in repair work to siding, framing, and interior walls.

4. Required by Building Codes

Many building codes now mandate kickout flashing due to its role in preventing water intrusion and maintaining home durability.
