What's Included
Our Chimney Flashing Installation
Old Flashing Removal
Failed flashing, old sealant and damaged roofing around the chimney are carefully removed.
Step Flashing
Individual step flashing pieces are woven in with each course of roofing along the chimney sides.
Counter Flashing
Counter flashing is cut into the mortar joints and lapped over the step flashing for a two-layer seal.
Cricket Installation
Wider chimneys get a cricket behind them to divert water and debris around the chimney instead of letting it pool.
Sealing & Water Test
Joints are sealed with a weather-rated sealant and the finished flashing is checked for a watertight fit.
Why It Matters
Proper Flashing Is Layered, Not Caulked
Many chimney leaks happen because the flashing was installed as a single piece or held in place mostly by caulk. Sealant alone breaks down within a few years, especially with the temperature swings and constant moisture we see in Gresham.
Correct chimney flashing uses overlapping layers so water is shed by gravity, with sealant as a backup rather than the main defense. That is the standard we install to on every chimney.

Signs You Need a Chimney Rebuild in Gresham
Crumbling or Missing Mortar Joints
Severely deteriorated mortar between bricks, often called spalling, weakens the chimney's structural integrity and typically indicates the damage has progressed beyond simple repointing repairs.
Leaning or Visibly Tilting Structure
A chimney that appears to lean or shift from its original position signals serious foundation or structural issues, often requiring a full rebuild rather than partial repair.
Extensive Cracking Throughout the Structure
Widespread cracks running through multiple bricks or sections, rather than isolated spots, suggest significant structural deterioration that surface repairs won't adequately or safely resolve.
Falling Bricks or Debris
Bricks or mortar chunks falling from the chimney indicate advanced structural failure, posing safety risks and signaling the chimney has reached the end of its usable lifespan.
Persistent Water Damage Despite Repairs
If water intrusion continues even after flashing and repointing repairs, it often means the chimney's core structure has been compromised and needs complete reconstruction.
Chimney Age Exceeding 50 Years
Older chimneys built with outdated materials or techniques often reach a point where ongoing repairs become impractical, making a full rebuild the more cost-effective, safer long-term solution.
