Roof cleaning (low-pressure) — Redwood City
Treat moss and algae on composition shingles without granule loss.
Whether you’re near the marsh or up in the hills, we remove tire marks, irrigation stains, and organic buildup from concrete and pavers. House washing brightens stucco and fiber cement without forcing water behind panels. Walking every roof isn’t always necessary or wise. Where appropriate, we apply manufacturer-aligned treatments that target gloeocapsa magma streaks and moss at the edges, then rinse gently or let rain finish the cycle per product guidance.
Why homeowners call us
- Focus on longevity of shingles—not a cosmetic blast that voids warranties
- Gutter face and downspout outsides rinsed when roof package is selected
