What's different about roof cleaning and repair in San Francisco

San Francisco's roofs sit in a mild, dry-summer marine climate — cool, foggy summers and average temperatures near 65°F, with almost all of the city's 23 inches of annual rain falling between October and April. That long dry stretch followed by a wet season is exactly the cycle that lets moss and algae take hold on roofs across neighborhoods like Noe Valley and the Sunset. Freezing and hail are rare here, so a roof's real enemy is moisture and shade, not ice, which is why timing a cleaning ahead of the rains matters more than guarding against winter freeze damage.

Much of San Francisco's housing dates to before 1970, including a large share built before 1940, and the city is dominated by attached Victorian and Edwardian row houses and low-rise multi-unit buildings in areas like Bernal Heights, the Mission, and Pacific Heights, often sitting on slab or raised wood foundations. Many of these older roofs are steeply pitched, which adds cost and calls for a crew comfortable with harness and roof-jack work. Roof cleaning itself doesn't require a license, but any actual repair, especially re-roofing, should go to a licensed contractor and typically needs a permit from San Francisco's Department of Building Inspection.

What moves the price in San Francisco

Nearly all of the city's rain falls Oct–Apr, feeding moss growth on older roofs.
Dense pre-1970 Victorian and Edwardian row houses often have steep pitches needing harness work.
Re-roofing needs a DBI permit; routine roof cleaning is unlicensed maintenance work.
July–September is the driest window, ideal for treating moss before fall rains return.

Licensing and permits in California

Roof cleaning itself is unlicensed exterior-maintenance work in most US states and Canadian provinces (no specialty trade license required, though liability insurance and fall-protection compliance are standard for reputable crews); actual roof REPAIR work should be handled by a licensed general contractor or roofing contractor, and any electrical or structural issue uncovered during a job should be referred to the relevant licensed trade.

In California, residential building permits are issued by the local city or county building department (not the state), applying the California Building Standards Code plus any local amendments — so exact rules and fees vary by jurisdiction and it's worth confirming specifics with the local building department. In San Francisco, permits come from the San Francisco Department of Building Inspection (DBI) – Permit Services.

Tax: Per CDTFA Publication 108, pure repair labor is generally NOT taxable when the contractor returns the customer's own item and does not substitute a different part; but installation and fabrication labor IS taxable in California regardless of whether it's itemized separately or bundled into a lump-sum price — so a home-service invoice can be part-taxable (materials + install labor) and part-exempt (pure repair labor on the customer's existing item) depending on the work performed.

Best time to book in San Francisco

Book in late summer (July-September): moss and algae are driest and easiest to kill, and treatment gets ahead of the fall rains that feed regrowth. Peak demand: July, August and September. Typical job length: 2-5 hours.

DIY or pro? Light DIY rinsing with a garden-hose-mounted cleaner can knock back mild surface algae, but moss removal, harness/roof-jack work on steep pitches, and any pressure washing are best left to a pro to avoid shingle damage, warranty voidance, or falls.
