Your roof is one of the most valuable parts of your home, but it’s also one of the easiest to overlook. Black streaks, algae, moss, lichen, and years of dirt buildup don’t just make your roof look old—they can trap moisture and contribute to premature deterioration. In San Francisco, the combination of coastal fog off the Pacific and salt-laden air from the Bay accelerates that wear. We’ve seen it firsthand on Victorians in the Haight and mid-century homes in the Sunset.
At Fox Window & Gutter Cleaning Services, we’ve been helping homeowners right here in San Francisco since 2011 with professional roof cleaning solutions that safely restore roofs while protecting their long-term performance. Honestly, not every roof is the same. The clay tiles common in Noe Valley need a different touch than the asphalt shingles you’ll find in the Richmond. Our experienced team uses the appropriate cleaning method for your specific roofing material, delivering outstanding results without unnecessary risk.

We believe every roof deserves the right approach—not a one-size-fits-all solution. San Francisco homes, with their Victorian-era shingles or modern flat roofs, each tell a different story. That’s why we take the time to understand what your property needs before we touch a single shingle.
We inspect your roof's condition, identify areas of buildup, and determine the safest cleaning method. In neighborhoods like the Castro or Pacific Heights, we've seen how decades of fog and salt air can create stubborn moss on clay tiles.
Every roof is different. We tailor our cleaning process based on your roofing material and its condition. A tar-and-gravel flat roof in SoMa needs a different touch than the cedar shakes you'll see near Twin Peaks.

San Francisco’s 808,000 residents live across 49 square miles, from the fog-bathed outerlands of the Sunset to the dense urban corridors of SoMa and the Marina. The city’s microclimates mean a home in the Castro might see weeks of June fog while the Mission bakes in sunshine—both conditions deposit salt spray, dust, and pollution on windows differently. With over 1.2 million commuters streaming in daily across the Bay Bridge and through BART, airborne grime from traffic and construction settles on every pane, especially in neighborhoods like Pacific Heights where historic bay windows capture the worst of it.
The local economy—driven by tech, biotech, and tourism—keeps residents busy, but also brings unique window challenges. Salt-laden fog from the Pacific coats windows in the Richmond and Sunset districts, requiring more frequent cleaning to prevent etching. In downtown and SOMA, high-rise condo associations deal with accumulated dust from constant development, while Victorian row houses in Alamo Square need careful hand-wiping to preserve original wood frames. Whether you’re in a loft near AT&T Park or a condo overlooking Golden Gate Park, San Francisco’s specific blend of fog, wind, and urban pollution makes professional window cleaning a practical necessity.
The heavy fog that rolls into neighborhoods like the Sunset and Richmond carries salt and moisture that can etch glass and corrode aluminum frames if left too long. We recommend cleaning every 6-8 weeks for properties west of Twin Peaks, versus every 10-12 weeks for areas east of Van Ness that get less marine layer.
Yes—original single-pane windows in Victorians have delicate wood sashes and leaded glass that can't handle high-pressure washing or harsh chemicals. We use soft bristle brushes and a low-moisture technique to protect the historic character while removing the city's fine pollution film.
San Francisco requires that all exterior window cleaning on buildings over three stories comply with Cal/OSHA Title 8 safety standards, including certified anchor points and fall protection plans. Many condos in SOMA and Financial District also have HOA rules limiting bell-systems or water runoff—we're fully insured and trained for these local requirements.
