Roof Wash - Cleaning Colorsteel Roofs with Bio-Shield®

 

Cleaning Colorsteel Roofs

 

Colorsteel roofs will get a build up of lichens and black fungal growths 4 to 5 years after installation.

This lichen growth causes severe damage to the Colorsteel coating so it should be removed as soon as it is visible on the roof.

 

How to Clean and Maintain Colorsteel Roofs

A Colorsteel roof should only be water blast cleaned as preparation for repainting, never to remove lichen growths.

The best and safest method to clean and maintain a Colorsteel roof is to treat the entire roof with Bio-Shield® or similar biocide solution.
Treatment with Bio-Shield® will kill all lichens and fungal growths on the roof and then weather action will gently remove the dead growths over a 3 to 12 month period.

Regular applications of Bio-Shield® every 2 to 3 years will keep the roof clean and prevent damage caused by lichens.

Unwashed Areas

The manufactures of Colorsteel and Colorbond roofing also recommend that any unwashed areas are flushed with clean water about every 6 months. 
An unwashed area is defined as an area of roof that is not exposed to rainfall.
These unwashed areas allow a build up of airborne contaminants that will cause corrosion and failure of the steel.  Unwashed areas are typically found on sections of roofs sheltered by eaves, on the under side of spouting and fascia and on the upper sections of Colorsteel garage doors.

The home owner is able to clean these areas in a simple and highly effective way to stop the build up of contaminants - just hose down the area with clean water every 6 months. 

More frequent hosing will be required for locations near the sea.

Roof Wash Ltd are genuine specialists in roof cleaning with over 33 years experience and more than 8000 roofs cleaned and treated with Bio-Shield.

We see many roofs that have not been treated properly, by 'specialists' and 'experts'.  The lichen is killed and removed but the black fungal growths remain.  In fact, if these black fungal growths have not been effectively killed they will develop a resistance to further treatments.
Bio-Shield application is specifically designed to kill black fungal growths as well so don't take the chance of a failed treatment and a roof that will not clean up

The Bio-Shield application for Colorsteel is specialised for this type of roof to kill not only the lichens and also the more widespread and harder to kill black fungal growths.

This unique application will give the best result - a clean roof.
