About This Job
This terracotta roof was covered in lichen, mould and algae. We applied a low-pressure chemical treatment that kills the organic growth without blasting the tiles. The after photo shows the roof straight after treatment: the lichen is already dead and bleached, and it will keep weathering away naturally over the following weeks.
