From Baywood's shaded shingle roofs to tile in San Mateo Park, roof growth here follows the trees — and San Mateo has plenty. Our soft wash kills moss and algae at the root instead of blasting the surface, which is why the results hold 2–3 years instead of one season.

Real before & afters from this service across the Peninsula.
We soft wash exclusively on roofing — low pressure, biodegradable detergent, and dwell time that kills moss, algae, and lichen at the root instead of blasting it off the surface. High pressure strips shingle granules and cracks tile, which is why we never use it up there.
Every roof job includes clearing valleys and ridge lines of debris, checking flashing and visible penetrations, and photographing the finished work. Results typically last 2–3 years.
San Mateo specifics: San Mateo runs the full range — downtown bungalows, Baywood and Aragon's tree-lined streets, Hillsdale ranches — and the mix of stucco, wood siding, and older brick keeps every job a little different. We work Baywood, Aragon, San Mateo Park, Hillsdale, and Shoreview regularly.
Common Burlingame service calls: moss removal from shaded roofs, brick walkway restoration in Burlingame Park, driveway cleaning in Easton Addition, and gutter clearing across the whole city after the rainy season.
Hot-water pressure washing that lifts oil, algae, moss, and years of grime from concrete, brick, pavers, exposed aggregate, and stone — without stripping the surface.
Low-pressure, biodegradable-detergent washing for roofs, siding, stucco, and anything delicate. Kills moss, mildew, and algae at the root — 4–6x longer-lasting than blasting.
Hand-cleared gutters, flushed downspouts, and a full inspection for damage or sagging. The cheapest form of water-damage insurance your home will ever get.
Streak-free exterior window washing for residential and light commercial properties. We reach the high ones, detail the frames, and leave glass you can actually see through again.
Our roof had moss so thick you couldn't see the tile. Nick's crew treated it, explained everything, and it still looks clean two years on.

Most San Mateo roofs run from a few hundred dollars for a single-story to over a thousand for large, steep, or estate roofs. Size, pitch, material, and moss coverage set the price. Quotes are free and back within 24 hours.
Yes — it's the manufacturer-recommended method for shingle and tile alike. Low pressure plus the right detergent kills growth at the root without stripping granules or cracking tile.
Typically 2–3 years. Heavily shaded San Mateo roofs under tree canopy trend toward the shorter end.
Increasingly yes — California insurers review aerial imagery, and visible moss can trigger non-renewal. A soft wash returns the roof to insurable condition.
