Kickout flashing prevents water damage to walls and foundations. It redirects rainwater from walls to roofs.
Kickout flashing is a specially shaped piece of metal installed at the point where a roof edge meets a sidewall. This L-shaped component acts as a water diverter, channeling rainwater away from the wall and into the gutter system where it belongs.
Without kickout flashing, water running down the roof can flow directly behind the siding, leading to hidden moisture damage, rot, and potential foundation issues.
Material Matters: Made of metal (aluminum or copper), installed at roof edges. Quality materials resist corrosion and last for decades, providing reliable protection against water intrusion.
Critical Protection: Prevents water from entering walls and foundations. This small component can prevent thousands of dollars in water damage, mold remediation, and structural repairs.
Installation Timing: Essential to inspect and maintain during roof installation or replacement. Whether you're building new or replacing an old roof, kickout flashing should always be part of the specification.
Water is one of the most destructive forces affecting homes. When water repeatedly runs down a wall, it can:
Without kickout flashing, water can cause significant structural damage. Always ensure your roofing includes it for protection. During home inspections, I always check for proper kickout flashing installation—it's one of those small details that makes a big difference in long-term home protection.
