Chimney Flashing Repair in Portland
A chimney interrupts the roof surface and requires layered flashing to direct water around its sides, uphill edge, and downhill face. Failed step flashing, counterflashing, mortar joints, sealant, or surrounding materials can allow water to move into the roof and walls.

Warning signs
Signs of a chimney flashing problem
Watch for stains near the chimney, damp attic framing, rusted or lifted metal, cracked sealant, loose counterflashing, debris collecting behind the chimney, or recurring leaks after wind-driven rain.
What to know
Repair the detail, not only the surface
Smearing sealant over the joint may hide the symptom without rebuilding the water-shedding detail. A durable scope should identify which flashing layer failed and whether masonry, roofing material, or decking also needs attention.
What to know
Separate roof and masonry conditions
Water can enter through chimney caps, crowns, mortar, siding, or flashing. The assessment should distinguish roofing work from masonry work and explain when another trade is needed.
When to call
When chimney flashing repair is needed
Chimney flashing repair is one of the most common leak calls in Oregon. Water that shows on a ceiling near a fireplace often entered at step flashing, counter flashing, or a missing cricket.
Rusted or pulled counter flashing
Masonry joints and metal laps fail after years of wet weather.
No cricket on a wide chimney
Water can pond on the upslope side and work under shingles.
Mortar gaps at the chimney base
Open joints let water behind the flashing.
Leak only during wind-driven rain
Side laps and corners take weather from a specific direction.
Prior tar on the chimney step
Surface sealant is a short-term cover, not a flashing repair.
Inspection focus
What chimney flashing repair should inspect
A useful chimney flashing repair visit should look past the first stain and document the parts of the roof that move water in Oregon weather.
- Step flashing woven into the roof covering
- Counter flashing let into the masonry

Scope factors
What affects chimney flashing repair scope
Chimney flashing repair can be a localized metal and masonry detail, or it can require surrounding shingle work. The chimney size, roof slope, and condition of the adjacent covering all matter.
Masonry condition
Spalled brick or open joints may need work beyond the metal.
Roof covering around the chase
Damaged shingles have to be integrated with new flashing.
Access and chimney height
Staging changes cost and schedule, which the contractor should put in writing.
Prior coatings
Old tar can hide the real laps and complicate a clean repair.
