What Is Soft Wash Roof Cleaning?

Soft wash roof cleaning is a low-pressure method that removes dirt, algae, moss, and lichen from roofs without causing damage. Unlike pressure washing, it uses biodegradable cleaning solutions and a gentle water rinse — making it safe for tiles, shingles, render, and delicate roof materials.

Cardiff Window Cleaner Ltd uses this method to safely restore roofing surfaces without cracking tiles or compromising the structure.

Soft Wash Roof Cleaning Chemicals

The cleaning solutions used in soft washing are specially formulated to break down organic growth without harming the roof or surrounding areas.

Cardiff Window Cleaner Ltd uses industry-approved, biodegradable soft wash chemicals that:

  • Kill moss, algae, mould, and lichen at the root
  • Prevent regrowth for longer-lasting results
  • Are safe for pets, plants, and surrounding surfaces when applied correctly
  • Comply with environmental and health & safety standards

Every solution is selected based on your roof type and level of contamination.
