Best Practices Manual

6.1 Kick-Out Flashing
Whenever a roof surface abuts a vertical wall surface, moisture intrusion and rot become a risk at the connection between the two planes.
Kick-out flashing, a somewhat forgotten practice except by the best roofers, addresses this risk at the most vulnerable intersection between sloped roofs and walls: the drip edge.
