Step flashing is used where shingles meet a vertical wall. In Fremont Hills MO, damaged or missing step flashing can let water run behind siding, trim, or brick and create stains that may look like a roof leak, wall leak, or both.
Quick answer:
If you are searching for roof flashing repair near me in Fremont Hills MO because stains appear near a wall or dormer, step flashing should be checked. Missing pieces, buried flashing, old sealant, and lifted shingles can all cause leaks.

What Step Flashing Does
Step flashing is installed in small overlapping pieces along a roof-to-wall joint. Each piece works with a shingle course to move water down the roof instead of letting it enter behind the wall covering.
Signs of Step Flashing Failure
Warning signs include stains near exterior walls, damp attic areas, peeling paint, water marks below dormers, loose siding, cracked caulk, or shingles that look lifted where they meet a wall.

Why Caulk Is Not Always the Fix
Caulk may slow water for a short time, but step flashing needs to be installed correctly under the shingles and wall materials. Covering a flashing problem with sealant can hide the issue while water continues to enter.
Where Step Flashing Problems Show Up
Common areas include dormers, additions, chimneys, porch roof tie-ins, and walls above lower roof sections. These spots carry a lot of runoff during heavy rain and need proper water direction.
Repair Options for Step Flashing Leaks
Repairs may include replacing damaged flashing, correcting shingle placement, adding kick-out flashing, repairing siding or trim, and checking nearby gutters. The repair should move water away from the wall joint.
