Moss holds water against your tiles, blocks gutters and, in winter, can lift tiles as it freezes. On a lot of Sussex roofs, especially under trees and on north-facing slopes, it builds up fast.
We remove moss by hand, treat the roof with a biocide to slow regrowth, and clear the gutters afterwards. We avoid high-pressure jet washing on tiles, because it can strip the surface and shorten their life.

Should I worry about moss?
A light covering is mostly cosmetic. Thick moss is worth dealing with because it traps moisture, blocks drainage and can lift tiles. Read our guide to moss on roofs.
Why we avoid jet washing tiles
High-pressure washing can blast away the surface of concrete and clay tiles and force water under them. A gentler hand clean and treatment is kinder to the roof.
Common questions
How long does moss take to come back?
It varies with shade and aspect. A biocide treatment slows regrowth, and occasional re-treatment helps keep it at bay.
Do you clean conservatory roofs?
Yes, we can clean conservatory roofs and gutters.
