Soft Wash Only

Streak-Free Shingles, Zero Damage.

Those black streaks aren’t dirt — they’re algae eating your shingles’ limestone filler. Blasting them with high pressure voids warranties and shortens roof life. Our soft wash applies an algae-killing treatment at garden-hose pressure, then rinses gently. The roof looks new, and the granules stay where they belong.

  • Black streak & algae removal
  • Moss & lichen treatment
  • Tile, metal & shingle safe
  • Gutter & fascia rinse included

Roof Cleaning FAQs

High pressure is not — it strips granules and voids most shingle warranties. That’s why we never use it on roofs. Our soft wash cleans at under 100 PSI, which every major shingle maker approves.

Most roofs stay streak-free for 2–4 years after a soft wash with inhibitor. Shaded, north-facing slopes may need a touch-up sooner — covered free within the first year.

Only when we must, with proper fall protection and soft-soled shoes. Most treatments are applied from ladders and the ridge line, keeping foot traffic — and risk — to a minimum.
