San Francisco's mature urban tree canopy — cypress, eucalyptus, liquidambar — drops debris year-round. Properties throughout the Richmond, Sunset, Mission, and Noe Valley accumulate significant organic material on roofs and in gutters between services. The city's wet season runs November through March, and clogged gutters going into that window mean overflowing water that bypasses the drainage system entirely — directing rainfall against fascia, soffits, and foundations rather than away from the structure.
San Francisco has an unusually high proportion of flat and low-slope roofs. Flat roofs drain through internal drains and scuppers rather than gutters — and those drains collect debris just as gutters do. Blocked roof drains create standing water on the membrane, which accelerates deterioration and eventually finds its way inside. We clear roof drains and scuppers as part of the service on flat roof properties.
Organic debris — leaves, twigs, seed pods, and compacted sediment — from gutters and gutter guards. Moss growth on roof surfaces and in valley areas. Downspout blockages flushed with water. Roof debris removed from valleys, hip intersections, and flat membrane surfaces. The drainage system leaves working the way it should.

Once or twice a year for most properties. The city's mature street trees drop debris year-round. The wet season (November through March) is the highest-risk window for debris-clogged gutters causing overflow and water intrusion.
Clogged gutters overflow during rain, directing water against fascia, soffit, and foundation. In San Francisco's older housing stock with wood framing, water intrusion from overflowing gutters can cause significant rot and structural damage over a single wet season.
Yes. San Francisco has a high proportion of flat and low-slope roofs — particularly in the Mission, Castro, and Richmond districts. Flat roofs drain through internal drains and scuppers rather than gutters. We clear roof drains and remove debris from membrane surfaces as part of the service.
Yes. Wet organic debris sitting on a roof surface retains moisture against the roofing material. On flat roofs with membrane, this accelerates degradation. On pitched roofs, it traps moisture that promotes algae and moss growth and can work under the shingle layer.
