Roof Cleaning – Safe for Tiles, Slate & Render

Unlike pressure washing, which can strip protective coatings and dislodge tiles, our soft-wash system uses low-pressure application and specialist biocides to gently remove moss and kill organic growth at the root.

This delivers long-lasting results while keeping your roof fully protected.

We clean and treat:

  • Slate and tile roofs

  • Flat roofs and garage roofs

  • Rendered roof surfaces

  • Conservatory roofs

  • Commercial and industrial rooftops

Our Roof Cleaning Process

  1. Inspection – We assess the roof condition and check for any damage.

  2. Moss Removal – Manual or soft-brush removal of moss and debris.

  3. Soft-Wash Treatment – Application of eco-friendly biocide to kill algae, lichen, and organic growth.

  4. Final Clean – Gentle rinse where required for a spotless finish.

  5. Optional Gutter Clearance – Ensure the system is free-flowing after moss removal.
