Portland homeowners deal with a unique combination of problems: heavy rainfall that continuously deposits algae spores, overcast skies that prevent UV-driven die-off, and significant shade from the Pacific Northwest tree cover. The result is green algae and moss that grow on every north-facing and shaded surface, year-round.
Portland also has a high proportion of older homes with cedar siding and shingles — one of the most moss-vulnerable surfaces in exterior cleaning. Cedar requires soft wash specifically designed for wood, not the vinyl-focused solutions many national companies use.
