Which cleaning method suits your London and the South East property?
Biocide soft-washing
Recommended for historic clay, slate, and fragile tiles. We manually remove bulk moss, then apply an HSE-approved fungicidal wash that penetrates porous tiles and prevents regrowth for up to 36 months. Ideal for shaded, north-facing roofs common in London and the South East.
Deep pressure washing
Suitable for durable concrete and modern clay tiles in good structural condition. Calibrated water flow strips established moss and lichen quickly — often used on newer estates and commercial units where tiles can withstand higher pressure.
Local roof conditions in London and the South East
The local climate and surrounding foliage in London and the South East frequently accelerate moss, lichen, and algae growth on roof tiles. Humid winters and shaded tree cover mean roofs in London and the South East often need preventative treatment every few years rather than waiting until tiles are fully saturated with growth.
Every treatment programme is calibrated for the moss and lichen variants we see on local roofs — avoiding unnecessary pressure on fragile tiles while ensuring durable surfaces are cleaned thoroughly.
