Kickout flashing diverts concentrated roof runoff away from the wall at the end of a roof-to-wall intersection

When kickout flashing is missing, too small, poorly integrated, or bypassed by the gutter, water can continue behind or across stucco instead of being directed into the gutter. Because the flow is concentrated at one point, the resulting damage can extend into the weather-resistive layer, sheathing, framing, and openings below.

Inspect the whole roof-wall termination

The kickout works with step flashing, counterflashing, roofing, the gutter end, fascia, stucco clearance, and the wall drainage system. A repair that adds only a surface diverter without integrating these pieces may not control the concealed water path.

Look for evidence below the intersection

Staining, recurring cracks, swollen trim, corrosion, soft material, or repeated sealant patches below the roof end can indicate chronic wetting. The visible damage may appear well below the actual entry point.

Use controlled testing or selective opening when the laps are hidden

If exterior observation cannot establish how the flashing and wall barrier overlap, a focused water test or limited opening may be needed. The purpose is to reveal the transition without unnecessarily dismantling a large area.

Do not seal away the wall’s drainage path

Surface caulk cannot recreate missing flashing and may trap water behind stucco. The repair should direct roof runoff into the gutter while allowing incidental wall water to drain as intended.

Verify both roof runoff and wall performance after repair

Check gutter alignment and focused drainage after installation, then monitor the lower wall through later rain. DreamPrint’s exterior waterproofing guide explains roof and stucco transitions in context. For a site-specific repair, continue to the exterior waterproofing service.
