Roof Cleaning FAQs
Everything you need to know about professional roof cleaning.
1Methods & Safety
Is pressure washing safe for my roof?
We use soft washing for roofs, not high-pressure washing. Soft wash uses low pressure with biocide treatments to safely remove moss and algae without damaging tiles.
What is soft washing?
Soft washing combines low-pressure water with specialist biocide solutions. It kills moss, algae, and lichen at the root, preventing quick regrowth.
Will you walk on my roof?
For most jobs, we work from ladders or cherry pickers. If roof access is needed, we use proper safety equipment and roof ladders to distribute weight safely.

How long does roof cleaning take?
Most roof cleaning jobs take 4-8 hours in a single day. The biocide treatment continues working for weeks after we leave.
How often should I clean my roof?
We recommend roof cleaning every 3-5 years, or when moss coverage becomes visible. Regular cleaning extends tile lifespan.
3Tile Types
Can you clean all roof types?
