Flashing failure around chimneys and skylights
Why it happens here
Stanton's temperature swings cause metal flashing to expand and contract. Over time, the sealant cracks and water gets behind it. This is the number one cause of roof leaks we see in the 90680 area.
Our approach
We remove the old flashing, clean the area, and install new flashing with proper step and counter-flashing. We seal it with roofing caulk rated for high temperatures. We also check the skylight frame and replace the gasket if needed.
