Why clean moss & lichen from your concrete tiled, clay or slate roof?

The toughest of the two villains in this story are the lichens. Moss is fluffy, does not hold on very strong and can be brushed off. However this not does mean that it won't regrow. You have to treat it to kill it off properly.

However lichens really hang on. Contrary to some beliefs the lichens don’t do any damage to the tiles themselves BUT if they get dense like the picture below they will definitely cause leaks if they grow in the gap between the roof tiles of a clay tile roof. This dense growth will inhibit your roof from clearing heavy storm water and over the years will definitely cause damage to the roof timbers. It could be that your roof insulation is soaking up the small leaks before any stains are evident on your ceiling.
With a correctly applied coating of our soft wash roof cleaning product you can enjoy a moss free roof for 2-3 years before any sign of re growth occurs.

Slate roofs are even more prone to damage from lichen growth as the lichens accumulate where the slates overlap and moisture can get into the roof timbers easily.
