Understanding Soft Wash Roof Cleaning

Soft wash roof cleaning safely and effectively removes dirt, algae, moss, lichen, and other contaminants from roofs using low-pressure water and specialized cleaning solutions. Unlike traditional pressure washing, which can damage delicate roof materials, soft wash roof cleaning is gentle yet highly efficient, ensuring the safety of your roof.

In contrast to other roof cleaning methods such as pressure washing or manual scrubbing, soft wash roof cleaning utilizes a lower pressure stream of water, typically less than 1000 psi, and environmentally friendly cleaning solutions. This approach ensures thorough cleaning without damaging the roof surface or surrounding landscaping.

The benefits of soft wash roof cleaning are numerous:

First, it removes unsightly stains and growths, restoring the roof’s appearance and curb appeal. 

Second, soft wash cleaning helps prolong the life of the roof by removing damaging contaminants that can compromise its integrity over time.

Third, soft wash roof cleaning is safer for both the roof and the environment; it’s also a responsible choice for homeowners and professionals who care about the planet.

  • Dwell Time: The cleaning solution can dwell on the surface for a specified period to break down and loosen the contaminants.
  • Gentle Rinsing: Using low-pressure water, the roof is gently rinsed to remove the dissolved contaminants, dirt, and grime.
  • Final Inspection: A thorough inspection ensures that all roof areas have been adequately cleaned and that any remaining stains or growths have been addressed as needed.

How to Soft Wash a Roof

Step-by-Step Guide to Performing Soft Wash Roof Cleaning:


  • Inspect the roof for damage and ensure all repairs are completed before cleaning.
  • Clear the surrounding area of any items that could be damaged by cleaning solutions.
  • Protect plants and landscaping by covering them with tarps or plastic sheeting.

Mix Cleaning Solution:

  • Prepare the cleaning solution according to the manufacturer’s instructions. It typically involves a mix of water, bleach, and surfactants.

Apply the Cleaning Solution:

  • Using a low-pressure sprayer, apply the cleaning solution evenly across the roof surface, starting from the bottom and working upwards to prevent streaks.
  • Ensure thorough coverage, especially on heavily stained or mossy areas.

Dwell Time:

  • Allow the cleaning solution to sit on the roof for the recommended dwell time, usually 15-30 minutes, to break down contaminants effectively.

Rinse the Roof:

  • Rinse the roof thoroughly with low-pressure water to remove the cleaning solution and dislodged contaminants.
  • Start from the top and work downwards to ensure complete removal.

Final Inspection:

  • Inspect the roof for any remaining stains or debris and reapply the cleaning solution if necessary.
  • Rinse any areas that may need additional cleaning.

Tips and Tricks for Achieving Optimal Results:

  • Choose the Right Day: Perform the cleaning on a cloudy day to prevent the cleaning solution from drying too quickly.
  • Use Proper Safety Gear: Wear protective clothing, gloves, goggles, and non-slip footwear to ensure safety.
  • Consistent Application: Apply the cleaning solution evenly to avoid streaks and uneven cleaning.
  • Monitor Weather Conditions: Avoid cleaning if rain is expected within 24 hours to ensure the solution has enough time to work.

Common Mistakes to Avoid During the Soft Wash Process

  • Using High Pressure: Avoid high-pressure water, which can damage roofing materials and reduce the roof’s lifespan.
  • Inadequate Dwell Time: Ensure the cleaning solution is given enough time to break down contaminants before rinsing.
  • Ignoring Safety Precautions: Use proper safety equipment and procedures to prevent accidents and injuries.
  • Overuse of Chemicals: Follow manufacturer instructions for mixing cleaning solutions to prevent environmental harm and roof damage.
