Chimney Leaks in Portland, OR

Chimney leaks are one of the most common calls we get after heavy Portland rain. Brick is porous, crowns crack, flashing fails, and water finds a path into attics and living rooms. The good news: most leaks are fixable when you catch them early.

Top Causes of Chimney Leaks

1. Cracked or missing crown — water enters from the top of the stack
2. Failed roof flashing — leaks at the chimney-to-roof joint
3. No chimney cap / rusted chase cover — rain and animals enter the flue
4. Open mortar joints / spalling brick — water soaks into the masonry
5. No waterproofing — porous brick absorbs months of PNW rain

How We Stop Chimney Leaks

We inspect systematically from the firebox to the crown, then fix the actual entry points — not just the stain on the ceiling. Typical solutions include crown rebuild, flashing replacement, cap or chase cover install, masonry repair, and breathable chimney waterproofing.

Cost Reality

A small fix (cap or waterproofing) can be a few hundred dollars. Ignoring leaks often leads to a multi-thousand-dollar rebuild. See our waterproofing cost guide and chimney repair Portland OR page for next steps.
