Your roof is constantly exposed to Cornwall’s coastal weather—meaning moss, algae, lichen and salt buildup can cause serious long-term damage. At Cornwall Exterior Cleaning, we specialise in safe, effective roof cleaning that restores your roof’s appearance and protects it for years to come.
We use low-pressure soft washing, manual moss removal and specialist biocides to ensure a safe, non-damaging clean for slate, tiles, flat roofs and more.
