Leaking chimney flashing
Why it happens here
Chimney flashing takes the most abuse on any roof. In La Viña, intense sun cracks the sealant, and wind-driven rain pushes water behind the counter flashing. Older chimneys often have rusted pans.
Our approach
We replace the pan and counter flashing with new copper or galvanized steel. We reseat the counter flashing into the mortar joint and seal with high-temp polyurethane. We water-test before we leave.
