Moss Removal across Greater London

Moss holds water against your roof tiles like a sponge. As it spreads, it lifts tile edges, blocks the gaps that let rain run off, and sheds clumps into gutters and downpipes until they overflow. In frosty weather, the trapped moisture can freeze and damage the surface of the tiles. Clearing it keeps water moving off the roof as it should and helps the tiles underneath last longer. Older concrete tiles, with their rougher surface, often hold the most growth.

Ashlar Roofing removes moss by hand. It is scraped and brushed from the tiles carefully, working down the roof so tiles are not lifted or cracked, then a biocide treatment is applied to slow regrowth. Once the roof is clear, the debris is removed from gutters and downpipes so they can drain again. Any slipped, cracked or missing tiles found during the clean are pointed out to you, so they can be repaired before they let water in.
