Roof Cleaning in Adelaide

The chemical used in the soft wash treatment acts on organic matter and dries the moisture content out so that it will be removed. You may see white powdery spots left after the cleaning, but it is not permanent damage or discoloration. Just the organic matter turned into a powder, over time this will go away and typically after a single heavy rainfall you will see it dissapear.

We recommend roof cleaning once every two years to prevent the buildup of moss, algae, and debris, preserving its appearance and structural integrity. However, the frequency may vary based on factors like your location, climate, and surrounding vegetation. However, if the roof is being treated through the soft wash method it only needs to be done every 5 years.

Yes, but only when done correctly. The pressure cleaning method is a bit more abrasive and can only be done on tiled roofs with a walkable pitch. For metal roofs the soft washing method is the most efficient way of cleaning.

For tiled roofs pressure cleaning can remove the surface growth of lichen and moss but residual organic matter may be left behind within the gaps of the tile interfaces. With enough time, water and sunlight, there is no guarantee it won't be back. This is a more affordable method that shows a clearer result in a shorter period of time, and it has its place in our cleaning service.

 The cleaning solution used in soft washing typically contains biocides that target and kill the moss and lichen, while the low-pressure water rinse helps wash away the debris without the risk of damaging the tiles, unlike high-pressure cleaning which can cause harm to delicate roofing materials. This method ensures that the organic growth is killed and prevents future lichen and moss growth.
