Roof soft washing may be suitable for a range of residential roofing applications, depending on the material and condition.
We can assess:
- Tile roofs
- Metal roofing

- Older or weathered roofs
- Roofs affected by mould or lichen
- Roofs with algae and environmental build-up
- Residential properties requiring ongoing roof maintenance
Our Process
-
Roof Assessment
01We begin by inspecting the roof to identify the roofing material, existing contamination, general condition and access requirements.
-
Property & Surface Preparation
02Before cleaning begins, we prepare the work area and take appropriate precautions around the property.
-
Cleaning Solution Application
03An appropriate cleaning solution is applied to the roof using suitable equipment and application methods.
-
Final Inspection
04Once the cleaning is complete, we inspect the roof and surrounding areas to make sure the work has been completed properly.
A Safer Approach to Roof Cleaning
Your roof isn’t the place for unnecessary high-pressure cleaning.
Roof soft washing uses low-pressure application combined with appropriate cleaning solutions to treat and remove organic growth and surface contamination.
Before any work begins, we assess the roof, consider its condition and determine the most appropriate cleaning method.

Absolutely outstanding job, cleaned very stubborn lichen off the roof (2 storey house) and the garage roof. Entire outside of the house cleaned , with no damage to paint work, front fence cleaned inside and out . All the painted surfaces look as new. Thought we would need to paint the fence- and now we don’t! Windows (outside) and the gutters were included. Hugo is an absolute machine, very thorough and a delight to engage with. We are very happy clients- highly recommend Sam and his team and look forward to engaging them again in the future.Posted on Google![]()

Got Questions? We Have Answers
Roof soft washing is a low-pressure roof cleaning method that uses appropriate cleaning solutions to help remove dirt, moss, mould, lichen, algae and other surface contamination.
Soft washing uses significantly less water pressure and is designed to reduce the need for aggressive cleaning. However, the appropriate method depends on the roofing material and condition of the individual roof.
Soft washing can help address moss and other organic growth. Depending on the amount and condition of the growth, additional treatment or follow-up maintenance may also be recommended.
Potentially. Older or weathered roofs require careful assessment before cleaning. We’ll inspect the roof and determine whether soft washing is appropriate for its condition.
There is no fixed schedule that applies to every property. Factors such as roof type, surrounding trees, shade, moisture and the rate of organic growth can affect how often cleaning is required.
Where required, gutter cleaning can be added to the service. If roof contamination or debris is likely to affect the gutters, we can recommend gutter cleaning as part of the overall exterior maintenance.
