Ceiling & Roof Leak Water Damage Repair in San Francisco, CA
Water-stained, sagging ceilings are dried, treated, and restored after roof leaks, plumbing failures, and upstairs overflows. A ceiling stain is the visible end of a leak that started somewhere above it, whether a roof detail, a supply line, or a failed seal. The work is tracing that source, drying the cavity above the ceiling, and repairing only once the leak itself has been corrected.

Frequently asked questions
The rain totals are modest. Why does the west side stay wet in July?
Because the marine layer is not rain. Summer fog condenses on cold west-side walls and window tracks for weeks at a time, and balloon-frame Victorians have no sheathing to stop that film from reaching the studs. The Bolinas gauge records a dry month. The siding does not.
Is bay fill a different job from dune sand?
Yes. Fill over mud holds a water table the estuary sets, so a Mission or waterfront basement can wet from below on a fair day. Dune sand on the west side takes December rain and moves it laterally under the floor. One job is groundwater. The other is a wick. Treating them as the same soil wastes the diagnosis.
A stain showed up two rooms from a known roof leak. How?
Balloon framing is a highway. There is no cavity to contain a leak, so water runs along the studs and plates and appears wherever a finish is weakest, often a room or two away. The stain is the exit, not the source, and scoping has to precede any cut.
