Flashing failure around chimneys and vents
Why it happens here
Anaheim's heat expands and contracts metal flashing season after season until the seal breaks. Once water gets behind the flashing it rots the surrounding sheathing. This is the number one source of leaks we find in Downtown and The Colony.
Our approach
We replace the flashing rather than just caulk over it, and we use a high-grade roofing caulk rated for high temperatures. We also check the sheathing underneath and replace any rot before closing it up.
