Why Soft Wash Roof Cleaning Is Better Than Pressure Washing

Many homeowners think roof cleaning means blasting the roof with pressure. That’s one of the fastest ways to damage shingles.

High pressure can:

• Strip protective granules
• Loosen shingles
• Force water underneath
• Void manufacturer warranties

Soft washing uses a low-pressure application combined with a professional cleaning solution that eliminates moss, algae, and lichen at the root.

The result: clean roof, no damage.

Roof Moss Removal in Portland’s Wet Climate

  • Portland’s shaded neighborhoods and long rainy seasons create the perfect environment for moss growth.

    Moss holds moisture against shingles, which can:

    • Shorten roof lifespan
    • Cause rot on cedar roofs
    • Lead to leaks
    • Increase long-term repair costs

    Our soft wash process doesn’t just remove surface moss — it treats the spores so regrowth is significantly reduced.
