Our process
How a job runs
- 01
Free survey and quote
We assess the roof from the ground and from a safe ladder position, check the moss and the gutters, and give you a clear fixed price.
- 02
Clear the heavy moss
Thick moss is gently removed and the gutters cleared, so the softwash treatment can reach the tiles underneath.
- 03
Softwash the roof
A biocidal treatment is applied at low pressure. It kills the algae, moss spores and lichen at the root without any risk to the tiles.
- 04
A roof that stays clear
The biocide keeps working for weeks. Because we treat the cause, the moss stays away far longer than a one-off scrape or blast.
