Roofing in San Francisco, run from our Eddy Street head office
San Francisco work runs from the head office on Eddy Street in the Western Addition. The housing here is some of the oldest in the country, and most roofs we see are flat or low-slope behind a parapet rather than a pitched roof you can see from the street.

San Francisco
Some of the oldest roofs in the country
The median home in San Francisco was built in 1948, the third-oldest of the 100 largest counties in the United States, and roughly 45 percent of the city's housing dates to 1939 or earlier. Under a lot of those roofs sit original board decks, many generations of patches and flashing that has been sealed over rather than replaced.
A leak repair on a century-old building is detective work: the water may enter at a parapet cap or a chimney and travel along joists before it shows. We trace it from the ceiling up and photograph what we find before proposing anything.
San Francisco
Flat roofs, parapets and roof decks
Victorian and Edwardian houses and the city's flats usually have low-slope roofs hidden behind decorative parapets. The parapet caps, the scuppers that drain through them and the seams at the base of the walls are where most leaks start. Many buildings also carry a walkable roof deck added later, over living space, which needs its own membrane and careful railing and threshold details.
San Francisco
Wind, fog and a wet winter
Ocean wind drives rain sideways under laps and flashings that would stay dry in a calmer place, and fog keeps north-facing roofs damp long after a storm. Most of the city's rain, like the rest of the Bay Area's, arrives in a few winter months, often in back-to-back storms, so fall is the time to have a flat roof's drains and seams checked.
