Kick out flashing should turn at about how many degrees?

Kick out flashing is a crucial component in roofing systems, particularly where the roof meets an exterior wall. Its primary purpose is to direct water away from the wall and towards the roofing system, preventing water intrusion and potential damage.

Turning the kick out flashing at approximately 120 degrees is considered most effective because this angle facilitates a positive angle for water drainage. When the flashing is installed at this angle, it helps ensure that water flows off the roof and away from the structure rather than running down the wall, which could lead to dampness, mold growth, or structural damage over time.

Other angles, while they might provide some level of protection, may not effectively channel water away. An angle of 90 degrees might not direct the water outward as efficiently, while angles greater than 120 degrees could potentially cause water to pool or flow back toward the wall, negating the purpose of the flashing altogether. Therefore, the 120-degree angle strikes a balance between effective water diversion and structural protection, making it the recommended standard for kick out flashing installation.
