Flashing failure around chimneys and vents
Why it happens here
Flashing takes the brunt of sun and rain, and the sealant around it dries out and cracks over time. On older Mainlands roofs, the flashing is often original and well past its service life.
Our approach
We replace the flashing rather than smearing new sealant over old. We use metal flashing and UV-rated roof sealant, then water-test the area before we leave. This is the fix that actually stops the leak.
