Roof moss removal
across Kent

Roof moss removal focuses specifically on physically removing moss and lichen and applying biocide treatment. Roof cleaning is a broader term that includes moss removal plus cleaning of general dirt, algae and weathering from the tile surface. We offer both — call us to discuss which your roof needs.

The biocide products we use are applied carefully and are generally considered safe once dry. We'll advise you on any precautions for plants or ponds near the property. Rain after treatment washes any residue safely into the drainage system.

Yes. Moss holds moisture against the tiles, which speeds up frost damage in winter as trapped water freezes and expands. As it grows it lifts and separates tiles, and on concrete tiles it breaks down the protective mineral coating. Clumps of moss also wash into the gutters and cause blockages. Removing it and treating the roof with biocide protects the tiles and helps extend the life of the roof.

After physical removal and a biocide treatment you can typically expect several years before moss re-establishes itself, though this depends on how shaded and damp the roof is — north-facing roofs and those under trees in Kent's climate tend to need attention sooner. The biocide kills the moss at the root rather than just removing the surface growth, which is why it lasts far longer than scraping alone.

Yes, always. Moss removal naturally dislodges material that falls into the guttering, so clearing the gutters of that debris is included as standard. We leave the whole system clear and flowing before we finish.
