Professional Roof Cleaning (Softwash)

Over time, roofs accumulate moss, algae, lichen, and other organic growth that can damage tiles and reduce the lifespan of your roof. Our professional soft wash roof cleaning service safely removes all biological growth without the risk of damage from high-pressure washing.

What is Softwashing?

Softwashing is a low-pressure cleaning method that uses specialist biocide solutions to kill and remove organic growth from your roof. Unlike traditional pressure washing, softwashing does not dislodge tiles or force water under the roof covering. The biocide treatment continues to work for months after application, preventing regrowth.

Benefits of Roof Cleaning

A clean roof enhances the appearance of your entire property. Removing moss and algae prevents moisture retention that can lead to tile damage and water ingress. It extends the lifespan of your roof covering and can improve the energy efficiency of your property by reducing heat-absorbing dark patches.

Safe and Effective

Our operatives are trained in safe working practices for roof cleaning. We use harnesses, ladders, and appropriate safety equipment. Our soft wash solutions are biodegradable and safe for surrounding plants and gardens when used as directed.
