Leaking chimney flashing on older homes
Why it happens here
Most homes near Altadena Library and Santa Rosa Avenue were built 40-60 years ago. The original step flashing and counter flashing have corroded or pulled loose. Every rain sends water behind the flashing and into the attic.
Our approach
We replace the step flashing and reset or replace the counter flashing. We use new copper or galvanized steel and seal it with butyl tape and polyurethane sealant. This is a permanent fix, not a patch.
