Soft Wash Roof Cleaning That Protects Your Home

At Pristine ProWash, we follow a low-impact, high-effectiveness approach to roof cleaning. We begin with a full inspection of your roof's condition, identifying moss severity, roof pitch, and surrounding plant life. Your landscaping is thoroughly soaked with water and a neutralizing agent to protect plants from any cleaning runoff before any solution is applied.

Our process starts with a professional soft wash application using a low-pressure, plant-safe mixture designed to kill moss and algae at the root without harming shingles. The solution is left to dwell and fully neutralize organic growth. In most cases, we let nature take its course. Dead moss naturally breaks down and washes away over the following weeks with weather exposure, ensuring zero physical damage to the roof surface.

For homeowners who prefer an immediate visual improvement, we offer an optional post-treatment blow-off, where we gently remove loose debris with air equipment or soft brushing on accessible areas. This step is ideal for pre-sale cleanups, HOA inspections, or high-visibility roofs. Our priority is always to balance a cleaner appearance with long-term roof health, avoiding aggressive scraping or high-pressure rinsing that can cause more harm than good.

Most Portland roof soft washing services fall between $250 and $450, with optional debris removal available for an additional fee based on roof size and condition. Every job is completed with before-and-after documentation, so you can see the difference while knowing your roof is being properly protected.
