Why Dormers Are Common Leak Areas
A dormer has roof-to-wall joints, corners, siding, windows, and flashing all meeting in one area. Each transition must shed water correctly. If one detail fails, water can enter behind the siding or under shingles.
Signs of Dormer or Sidewall Leaks
Watch for stains on sloped ceilings, paint bubbling near upstairs walls, damp trim, discoloration below dormer corners, loose siding, or shingles that look worn where the roof meets the wall.

Flashing Problems Around Sidewalls
Step flashing should move water away from the sidewall and onto the shingles. Missing, bent, short, or covered flashing can let water travel behind the wall covering and show up inside away from the visible roof edge.
Siding and Trim Can Be Part of the Leak
A dormer leak is not always only a roofing issue. Cracked caulk, loose trim, open siding seams, or window leaks can send water into the same area. A good inspection checks both the roof and wall details.
Repair Options for Dormer Leaks
Repairs may include correcting step flashing, replacing damaged shingles, sealing trim gaps, repairing siding, or improving kick-out flashing where water leaves the wall. The goal is to move water away from the joint.

It can be either or both. Dormers have roof, wall, siding, trim, and window details that all need to be checked.
