Moss holds water against the tiles and blocks gutters; manual removal and biocide extends roof life in Calne. Calne mixes a stone-built market-town core with Victorian terraces off the London Road and substantial post-war and modern estates on the edges. On this kind of stock, the common problems are nail sickness on the post-war estates, slipped tiles after wind, and failing Victorian leadwork in the older core — and knowing which you are dealing with is the difference between a lasting fix and money wasted.

Local Knowledge
Roof Cleaning in Calne
Roof cleaning in Calne addresses moss, lichen and algae accumulation that accelerates tile surface degradation. Conditions in Calne favour moderate moss growth, particularly on north-facing slopes and under tree canopy. 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 4–6 years before re-treatment is needed. A written roof condition report is included on every cleaning visit.

Good to know
Disruption, Mess & Weather
A day of quiet, external work with some moss debris coming down — we sheet below, protect the beds and clear everything away. You do not need to stay home for external work.
Removal runs year-round; biocide is applied in a dry window. Riverside and shaded roofs regrow faster and may need re-treating in 2–4 years. Calne sits in the Marden valley, so low-lying properties hold damp longer and the exposed edges catch the south-westerly weather.
