Roofing in San Francisco.
San Francisco is a flat roof city. Most homes hold a low slope roof behind a parapet, over rooms with no attic between them and the sky. Add Victorian gables, ocean fog and real wind, and it is a trade of its own. Flat roofing is one of our six core services, and this is the city that uses it.
The flat roof capital of the Bay.
Rowhouse roofs do not behave like suburban ones, and the difference is exactly where San Francisco leaks start.
Flat roofs behind parapets
The classic San Francisco roof is nearly flat, edged by parapet walls, drained by scuppers and internal drains that must never clog. The whole system works only as well as its lowest detail, so that is where our attention lives. Seams, drains, edge metal, coatings on sound surfaces.
Victorians and Edwardians up front
The street face is often a steep, ornamented gable that flattens out behind the ridge. Two roofs in one, meeting at flashings that have to be right. We work the ornament with care and the flat section with the respect low slope demands.
The avenues and their weather
Out in the Sunset and Richmond the fog is a resident, not a visitor. Salt air works on metal, damp slows every drying cycle, and wind drives rain into details that stay dry downtown. Materials and maintenance both need to respect the west side.

Answers to what San Francisco homeowners ask before anyone climbs a ladder. The wider list lives on the services page.
With a proper inspection of the roof above it. On a flat roof, water travels along the deck before it drops, so the stain rarely sits under the entry point. We trace it, photograph what we find and give you the fix in writing.
The parapet is the low wall where your roof meets the sky at the street line. It takes weather from both faces, moves with the building, and its cap and flashings are classic San Francisco leak points. Keeping them sealed is exactly the detail work our flat roofing service covers.
On a sound flat roof, yes. An elastomeric coating seals the surface against the constant damp. On a failing roof it is a bandage, and we will tell you which situation you have before any money moves.
