About This Service
Follow the Roof Junction
Chimney flashing repair concerns the metal transitions and connections where masonry meets roofing. A chimney flashing leak can show up below the roof junction, so the visible stain alone may not locate the opening. We examine the connection and consider how water is being directed around it.
Chimney step flashing follows the roof courses, while chimney counter flashing protects the upper connection to the masonry. An effective repair depends on these pieces working together. Adding surface sealant without understanding the assembly can leave failed or missing details concealed.

- Masonry chimney: the brickwork beside the roof junction.
- Counterflashing: covers the upper edge of the step flashing.
- Step flashing: one piece shown within the roof layers; the pieces follow the shingle courses.
- Shingle roofing: works with the flashing to shed water down the roof.
The arrows show intended drainage, not the source of a leak in your home. The actual roof covering and chimney construction determine the details that need checking.

Repair, Replace or Reflash
Chimney flashing replacement may be appropriate where metal is damaged, detached or unsuitable for the current roof. Chimney reflashing can involve coordinating with roof materials that must be lifted or renewed. We explain the extent of that work rather than describing every roof-junction problem as a small patch.
When you ask us to reflash chimney connections, tell us whether the roof was recently replaced or whether leakage began after other work. Flashing around a chimney needs a repair suited to the affected connection and adjoining materials. A separately damaged roof surface may require additional work outside the flashing itself.
Make the Finish Part of the Plan
The proposal should identify what is being retained, how the new connection joins the roof and masonry, and how affected finishes will be completed. Access and roof condition influence the work. We discuss those details before authorization so a partial scope does not leave an important junction unresolved.
Do not climb to inspect lifted metal yourself. Share the timing and location of indoor staining from a safe area. If the source is still uncertain, start with our leak assessment before choosing chimney flashing as the presumed cause.
Coordinate the Chimney Flashing Before Covering It
A useful repair sequence makes the responsibilities clear while the connection is accessible. Let us know if a roofer, mason or remodeling contractor is involved. We can discuss where the scopes meet instead of leaving a joint between two trades unassigned.
Keep the accepted flashing proposal with the property’s roofing records. It should identify the portion addressed and any excluded work. That record can help a future contractor understand the connection without assuming that the entire roof junction was replaced.
