Roof Cleaning
Lichen, moss and algae cause severe damage to the protective factory coatings on roofs.
These growths are difficult to remove with water blast cleaning alone. The lichen will begin to regrow immediately after pressure cleaning from the residue left behind.

The Easy Way to Clean and Protect Any Roof with Bio-Shield®
Follow these 3 simple steps to ensure a complete kill and removal of the lichen, moss and algae, and long lasting protection
Follow these 3 simple steps to ensure a complete kill and removal of the lichen, moss and algae, and long lasting protection
- Ensure the roof is dry before application
- Apply the Bio-Shield to saturate the growths
- On Coloursteel or Clay Tiles, apply a 2nd lighter coat after 10 to 15 minutes to re-wet the surface.
The key to successfully cleaning a roof is to apply the Bio-Shield solution to saturate the lichen, moss and algae through to the base of the growths, and ensuring it does not dry out to quickly. Aim to allow drying over 10 to 15 minutes to ensure the Bio-Shield gives a good kill. Application on a cloudy day or early morning will assist. You may notice a slight, temporary colour change as the Bio-Shield takes effect.
Clean up is effected by weather action as wind and rain remove the dead growths. This cleaning process can take as little as 3 months on a Monier tile roof, or up to 12 months on a heavily infested Coloursteel roof, and once clean, Bio-Shield can keep a roof clean for up to 3 years.
To maintain a treated roof, re-apply the Bio-Shield at the first sign of regrowth or every 2 to 3 years, for a fast clean up and to keep the roof surface clean.
