Softwashing & biocide — a gentler way to clean and protect.
Softwashing uses low pressure and specialist cleaning agents to lift organic staining from your roof. Paired with a biocide, it helps keep the surface cleaner for longer.
Why homeowners choose this service
- Low-pressure application designed for delicate roof surfaces
- Lifts algae, lichen and organic staining without harsh blasting
- Biocide treatment helps slow moss and algae regrowth
- Ideal follow-up to a hand-clean and moss removal
- Even, considered finish across the whole roof
Why softwash + biocide?
Where a hand-clean removes the bulk of moss and debris, softwashing addresses the organic staining that remains — the greens, greys and blacks that build up on tiles over time. A biocide treatment then helps slow the return of moss, algae and lichen.
This combination gives a more even, longer-lasting finish than a physical clean on its own.
Our process
A careful, methodical approach designed to protect your roof and your property.
Prepare the roof
We clear loose moss and debris first so the softwash can reach the tile surface evenly.
Apply the softwash
A low-pressure application lifts organic staining without the risks of high-pressure blasting.
Biocide protection
A professional biocide treatment helps slow the return of moss, algae and lichen.
Frequently asked
Is it safe for plants and pets?
We take care with application and rinse down where needed. Sensitive plants can be covered while we work — just let us know.
How long do the results last?
It varies with location, tree cover and exposure, but a biocide treatment typically slows regrowth for a long period.
Can I have softwash without moss removal?
Sometimes — if moss coverage is light. For heavier growth, a hand-clean first gives a much better result.
Do you use industrial pressure washers?
Not on the roof. Softwashing is deliberately low-pressure and much gentler on tiles.
