Central San Diego flashing repair in Hillcrest, North Park, and Mission Hills usually accompanies a roof replacement, and most roofers don't reflash properly.
How do I know it is the flashing and not the crown?
The pro does a leak diagnosis first. Crown leaks usually show up as efflorescence on the upper brick and water on the smoke shelf. Flashing leaks show up as wall stains at the ceiling line or in the attic where the chimney passes through. The pro confirms with a hose test, running water on each suspect area in turn while watching the interior.
Why did my new roof get installed without proper counter flashing?
Common shortcut. The roofer wraps L-flashing up the side of the brick and seals it with caulk. Looks fine on day one. Fails in 3–5 years when the caulk dries out. Proper counter flashing is set into a saw-cut groove (reglet) in the masonry, water-tight without depending on caulk.
