Chimney leaking water — San Francisco, California
Water entering around a chimney is one of the most common — and most damaging — roof leak sources. The leak usually originates from deteriorated flashing (the metal strips where the chimney meets the roof), a cracked chimney crown, damaged mortar joints, or a missing chimney cap. Because chimney leaks send water down hidden paths inside walls, the damage can progress for months before stains appear. A roofer handles flashing and roof-side repairs, while a mason addresses the chimney structure itself. Repair costs range from $200–$500 for reflashing to $1,000–$3,000 for crown and mortar rebuilds.

Winter rains expose roof leaks and drainage failures on the city's steep, hilly lots, while salt-laden fog accelerates flashing corrosion. Flat and low-slope roofs common on multi-unit buildings require specialized membrane maintenance to handle the prolonged wet season.
