Steps
Identify every location where a sloped roof plane terminates at a vertical wall, such as the end of a gutter run — this is where kick-out flashing is required
Install flashing that diverts water away from the wall at the base of the step-flashing run, per the current IRC roof-wall intersection provisions
Extend the flashing up the wall and over the roof surface by the minimum dimensions the code specifies, using corrosion-resistant metal of the minimum thickness required
Integrate the kick-out with the WRB and wall flashing so water is directed into the gutter rather than behind the siding
During a re-side tear-off, check for a missing or undersized kick-out and retrofit one before closing up the wall
Known gotchas
A missing kick-out flashing is one of the most common and costly defects found during siding tear-offs, often after years of hidden sheathing or framing rot
A kick-out that is present but not properly sized or integrated with the WRB behind it does not satisfy the intent even though metal is visible
