High pressure roof cleaning will remove all moss and grime to give the roof a fresh new look. An anti fungicide is added after to kill off any other remaining moss and delay further regrowth.
Grass and gravel areas are polythened to stop any debris and gutters are disconnected into a barrell to stop any undrground blockages. Any broken damaged tiles will be replaced before pressure spray begins.
Roof cleaning will revert the tiles back to their original colour, making the roof look as good as new. Any cement work will be added after if needed. There is no written guarantee with roof cleaning as all roofs will be different in terms of moss regrowth. Generally tho, roofs can last from 2 to 5 years before any visible regrowth.
