Moss holds water against the tiles and blocks gutters; manual removal and biocide extends roof life in Devizes. Devizes has one of the finest Georgian market-town cores in the West Country — brick and stone townhouses, clay and slate roofs, and a large conservation area, ringed by post-war and modern estates. On this kind of stock, the common problems are parapet-gutter and leadwork failure on Georgian townhouses, slipped slates, and conservation-grade roof repairs — and knowing which you are dealing with is the difference between a lasting fix and money wasted.

Local Knowledge
Roof Cleaning in Devizes
Roof cleaning in Devizes addresses moss, lichen and algae accumulation that accelerates tile surface degradation. Conditions in Devizes 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. On National Trust and conservation area properties we follow Historic England guidance throughout. 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.
