Exe riverside terraces with elevated humidity — victorian and post-war Cowick Street and surrounding streets. Fastest moss establishment in inner exeter; 2-year treatment cycle for cowick properties near the river, annual for those directly riverside.
Cowick’s specific characteristics create distinct moss removal requirements. The victorian and post-war housing stock in Cowick presents conditions that differ from Exeter’s post-war suburbs, and the correct specification for each job reflects the age, construction method and local exposure of the property.

Pressure washing is the most common roof treatment error we encounter on Cowick survey visits. The appeal is immediate visual transformation — a pressure-washed roof looks clean on the day. The reality is that pressure washing removes the weathered surface layer from both concrete and natural tile, creating a more porous surface that allows moss spores to establish faster than on an intact weathered surface. On Cowick’s Welsh slate stock, pressure washing strips the protective oxidised surface entirely, exposing fresh stone that weathers differently from the surrounding original material. The correct treatment method is low-pressure biocide application — the biocide kills the moss chemically, the die-back occurs over 2–6 months as natural weathering carries the treated growth away, and the tile surface is preserved intact. Re-establishment rates after biocide treatment are consistently slower than after pressure washing because the surface retains its natural weathered profile.
