What are the unique problems associated with softwashing man-made roof slates? (Part One) (video how-to)
We need to be cautious when softwashing man-made roofing slates.
Man-made roof slates often lose their coating over time, through natural weathering.
Cleaning the "biofilm" from roof slates may expose the fibre cement or other material the slate is made from, which, before softwashing, will have been covered over by organic growths.
The test patch in the photos below shows what can happen to very old slates
Bio Cleanze will "creep" up inside the laps better than other cleaning products, ensuring all the growths and spores are killed. In our experience this is the best way to give a softwash treatment to clean man-made roof slates.
Important: Always treat an out of the way test patch first and look for the tell-tale pitting of the tile coating before treating or cleaning the whole roof. Always obtain your customer's agreement that the results are acceptable and get their permission to treat the remaining roof surface.
