Attic Mold Removal in San Francisco, California
Attic mold is one of the most common findings during home inspections in San Francisco. It develops from inadequate ventilation, bathroom or kitchen exhaust fans routed into the attic rather than outside, or slow roof leaks that go undetected for months. Because attics are rarely visited, growth can continue well before discovery — often surfacing only when the home goes on the market.

The three most common causes of attic mold in San Francisco: first, exhaust fans — bathroom, kitchen, and dryer vents — that vent into the attic space instead of outside. This is a code violation but extremely common in older homes. Second, inadequate soffit or ridge ventilation that traps warm, humid air against the roof sheathing. Third, slow roof leaks that introduce moisture gradually without producing visible interior damage. Any attic mold job should begin with identifying which of these is the source. Removal without fixing the cause produces regrowth within months.
