🌿 Roof Cleaning – Low Pressure Soft Wash (3-Year Warranty)

Includes a built-in 90-day follow-up re-treatment

Preparation Checklist:

  • Make sure we have access to two working outdoor water spigots

  • Remove potted plants, furniture, and décor around the home’s perimeter

  • Notify us of any existing roof or gutter damage before service

Why Our Method Matters:

  • Using pressure washers, wire brushes, or harsh scrubbing can void your roof's warranty

  • The more abrasive the cleaning, the more risk of shingle damage

  • That's why Moss Boss uses a minimally invasive, two-step process recommended by major roofing manufacturers

Stage 1 – Initial Cleaning:

  • Technicians gently brush off large moss clumps using shingle-safe bristle brooms

  • We then apply a soft wash solution made of sodium hypochlorite and surfactant

    • Safe for plants (breaks down into salt after 15 minutes)

    • Ground technician actively waters vegetation to prevent damage

  • Gutters are cleaned out as part of the service

  • After the initial treatment, remaining moss may appear like cotton candy—light-colored and fluffy

    • This treated moss dies on contact and falls off naturally within 3–6 months

Stage 2 – 90-Day Roof Re-Treat:

  • Scheduled follow-up about 3 months later

  • We re-inspect the roof and gently remove any leftover moss

  • Additional soft wash is applied as needed for long-term protection

  • 3-Year Warranty:

  • Free re-treat if visible moss returns within 3 years

  • Warranty is void if another company services the roof during this period
