Moss holds water against the tiles and blocks gutters; manual removal and biocide extends roof life in Melksham. Melksham is a riverside market town with a Georgian and Victorian core by the Avon and extensive 1960s–90s estates spreading out from it. On this kind of stock, the common problems are accelerated moss on riverside roofs, nail sickness on the estates, and blocked valleys under the town's mature tree cover — and knowing which you are dealing with is the difference between a lasting fix and money wasted.
Roof cleaning in Melksham addresses moss, lichen and algae accumulation that accelerates tile surface degradation. The high ambient moisture in this valley location creates one of the fastest moss growth rates in our Wiltshire coverage area. Moss holds moisture against tile surfaces, mechanically lifts tile edges on concrete tile, and traps freeze-thaw moisture on clay and stone.
We use manual removal and soft-wash biocide — no pressure washing, which removes protective coatings from concrete tiles and fractures aged clay tile. NFRC-approved method. Biocide treatment after removal slows regrowth to every 2–3 years before re-treatment is needed. A written roof condition report is included on every cleaning visit.
We assess the moss coverage, tile type and condition, and set up safe access.
Moss is scraped and brushed off by hand — never pressure washed, which damages tiles.
A biocide is applied to kill remaining spores and slow regrowth over the following seasons.
We clear the moss debris from the gutters so it doesn't wash back down.
