Leaking chimney flashing after winter storms
Why it happens here
Canyon wind drives rain sideways into chimney flashing, and older flashing was not installed to handle that. Over time, the metal loosens and sealant fails. Rubio Canyon chimneys take more wind than almost anywhere in Altadena.
Our approach
We rebuild chimney flashing with heavier metal and mechanical fastening, not just sealant. We also check the chimney crown and cap while we are up there, because those are part of the same water management system.
