ROOF WASH

Whoa, is that the same roof?

Short answer... Yes, it is! On arrival to wash the tiled Annandale roof in the before and after images above, there was no indication that it belonged to this gorgeous peachy hue. Our Softwash system cleans your roof from ground-level (on most occasions) using low water pressure. 


TILES

Mould tends to attach itself and colonise on tiled roofs, "greying" their original bright colour, as seen above. Softwash is especially effective for cleaning tiled roofs, as water is not forced into places it doesn't need to be. Double bonus - fungus and damage-free! 

COLOURBOND

Colourbond roofs are more challenging to clean for three main reasons:

1. The tendency for the Colourbond to oxidize means that colour loss is imminent when it is cleaned.

2. Gloeocapsa magma (Gleo) seems to love Colourbond roofs. This ancestral bacteria's different structure means a greater number of Softwash applications are usually needed to break through it. Treatment 1 removes the outer tar-like coating. Treatment 2 kills any living bacteria still present. Treatment 3 works on any remaining sticky residue.


For the greatest results, it is best to leave the final Softwash application on, as it takes time for Gleo to be removed, with its short residual effect being between 12 hours and a few days. During this time, the final treatment kills any remaining residue and the dead remnants are weathered away. This process ensures your Colourbond remains on your roof and not down the gutter!


3. The smooth, non-porous surface of the Colourbond roof material makes it a more dangerous surface to be on!


Our equipment allows us to clean the roofs of single-level homes from ground level. Multi-level homes may find their clean costs greater due to the need to Softwash from hired lifting equipment i.e. cherry picker. We prefer to minimise costs for our customer. Therefore, the Softwashing of two roofs in a day, which will only occur where mould is present, and a cherry picker is required means that the hire cost can be shared. Happy days :-)

TIME FRAME

Many factors contribute to variations in the time it takes to complete a roof clean. Ranging between 3 - 12 hours, it's not just a matter of whether we will be dealing with Mould or Gleo, but also the length of time the fungus has been colonising on the surface. When left alone for a number of years, Mould and Gleo attach themselves to the roof's hard surface and the process of corrosion begins.


Example: The Colourbond roof belonging to one of our valued Kelso customers, unfortunately, was suffering from severe paint damage whereby the Gleo had caused large pieces of paint to lift and curl away from the roof underneath. Ouch! ;-(
