Roof Cleaning & Soft Washing in Liverpool & the North West
Soft washing that removes moss, algae and organic staining without damaging tiles.
Service overview
Roof Cleaning done properly
Roof moss is not just cosmetic. A saturated moss mat holds water against the tile surface, accelerating frost damage, and fragments constantly break away to block gutters and downpipes. On concrete tiles the growth works into the surface texture; on slate it lifts at the laps. Either way, the longer it is left the more the roof covering deteriorates.
We clean roofs by soft washing — low pressure combined with a purpose-made biocidal treatment. Pressure washing a roof is one of the most damaging things you can do to it: it strips the protective granular surface from concrete tiles, drives water under the laps and can dislodge mortar bedding on ridges and verges. Soft washing achieves the same visual result without any of that risk.
Where growth is heavy, we scrape the bulk moss first, clear the gutters of the fallout, then apply the biocide treatment which continues to kill spores for months after we leave. The roof keeps improving in the weeks following treatment as dead growth weathers off naturally, and regrowth is significantly slower than after a mechanical-only clean.

Benefits
The benefits of professional roof cleaning
Extends the life of the roof covering
Removing the moisture-holding moss mat reduces frost damage and slows the deterioration of tile and slate surfaces.
No high pressure on your roof
Soft washing avoids stripping tile granules, dislodging ridge mortar or forcing water under the laps.
Biocide treatment keeps working
Residual treatment continues to kill spores after the visit, so the roof stays clear far longer than a mechanical clean alone.
Gutters cleared on completion
Moss fallout is removed from gutters and downpipes as part of the job — we never leave the debris for you.
Dramatic kerb appeal improvement
A clean roof transforms the appearance of a property and is one of the highest-impact jobs before a sale or valuation.
Safe for render and conservatories
Adjacent render, cladding, glazing and planting are protected and rinsed down as part of the process.
How it works
Our roof cleaning process
- 1
Roof inspection
We assess the covering, pitch, condition and growth type, and identify any loose or damaged tiles before starting.
- 2
Moss removal
Heavy growth is scraped away and cleared, working safely from roof ladders or long-reach equipment as the roof allows.
- 3
Soft wash and biocide
A low-pressure biocidal treatment is applied across the covering to kill remaining algae, lichen and spores.
- 4
Clear down
Gutters, downpipes, paths and drives are cleared of fallout and washed off before we leave site.
