Roof Cleaning in Kent
Moss removal and softwash treatment, with the method chosen to suit the covering.
Roof cleaning is the job where method matters most. A concrete interlocking tile, a clay peg tile, a natural slate and a fibre cement sheet all respond differently, and the wrong approach can cost far more than the clean.
We assess the covering first, then choose between manual moss removal, softwashing with a biocide, or a combination. We do not treat high pressure washing as the default for roofs, because on many coverings it is not appropriate.
What the job includes
- Roof and access survey before quoting
- Manual moss removal and scraping where the covering suits it
- Softwash biocide application to treat algae, lichen and remaining spores
- Gutter and downpipe clearance of dislodged moss
- Ground level clear-up of fallen debris
- Powered access or safe working at height as the site requires
Roof coverings we work with
- Concrete and clay interlocking tiles
- Plain clay tiles
- Natural and fibre cement slate (assessed individually)
- Conservatory and outbuilding roofs
- Flat roof surrounds, fascias and adjoining render
Why it is done this way
What you get with our roof cleaning
Method matched to the roof
Scrape, softwash, or both — decided after looking at the covering, its age and its condition, not before.
Safety-first access
We use powered access platforms and safe working-at-height methods rather than improvising off a ladder.
Treatment, not just removal
Scraping takes the bulk off. A biocide treatment deals with what is left in the surface and slows how quickly it comes back.
Gutters cleared afterwards
Moss removal always sheds debris. Clearing the gutters is part of finishing the job properly.
Our process
How the visit runs
- Step 1
Survey
Inspect the covering, pitch, condition and access, and agree what is realistic.
- Step 2
Set up access
Position powered access or safe working platforms and protect the ground below.
- Step 3
Remove and treat
Take off the bulk of the moss, then apply biocide to the cleaned covering.
- Step 4
Clear gutters and site
Clear dislodged material from gutters, valleys and the ground.

“I can’t believe the change to the patio and paths surrounding the house! It has been transformed from a dull and depressing monotone with all kinds of dirt and growths in a matter of hours. Rez was a pleasure to have around, very polite and professional.”

Questions
Roof Cleaning FAQs
Can you clean a roof without damaging the tiles?
Yes, when the method suits the covering. Manual moss removal and softwashing are far gentler than high pressure water, which can strip the granular surface off older concrete tiles and force water under laps.
How do you remove moss from a roof?
Usually by lifting the bulk off by hand or with a scraper, then applying a biocide to kill the remaining growth and spores. The treated residue weathers off over the following months.
How often should a roof be cleaned?
There is no fixed interval. North-facing roofs and those under trees may need attention every few years; open, sunny roofs can go much longer. An annual look at the gutters usually tells you.
Do you use high pressure on roofs?
Only where the covering genuinely suits it, and it is not our default. On most domestic roofs we recommend manual removal and softwashing instead.
Will the roof look clean straight away?
After manual removal, yes, in large part. Where biocide is doing the work, the roof continues to improve over several weeks as the treated growth breaks down and weathers away.

Advice worth reading first
How often should you clean your gutters?
Most Kent homes need gutters cleared once a year. Heavy tree cover, a shallow roof pitch or a history of overflow pushes that to twice.
Softwashing vs pressure washing: which does your surface need?
Use pressure on paving and concrete. Use a low-pressure biocide softwash on roofs, render, cladding and paintwork. Getting it the wrong way round is what causes damage.
Seven signs your roof needs cleaning
Moss holding water against tiles, debris in the valleys and a gutter that keeps blocking are the three that matter most.
