Moss and Mould Treatment
Concrete or Clay tile roofs should not be walked on any more than absolutely necessary and the best process for these roofs is a moss and mould kill chemical treatment. These treatments (depending on the key ingredient) can take from 3 to 12 months before the roof is completely clean. We offer a 12 month warranty on all moss & mould cleaning treatments.
Mould build up as can be seen on the right in the above photo can quickly deteriorate into orange mould which has been scientifically attributed to a cause of asthma in young children.
In the left hand picture the lichen is actually lifting the tiles, it acts like a sponge absorbing water which drips into your roof.
