The Roof Cleaning Test
BIOCIDE TREATMENT
The final step in the process is to apply a
drench wash of premium biocide which
eliminates all traces of the moss and lichen
and stops regrowth for 3-5 years.
The roof will require further biocide

moss away.

THE CLEAN UP
As the downpipes have filters fitted to stop the moss from
entering the drains. The water run off moss etc. all comes to
ground level. Therefore, it is necessary to clean from the
top down the gutters are cleaned out, walls, windows, doors
and the ground level is cleaned and all the moss removed
from site.

remarkable. The roof will be clean and moss free however the roof tiles will be lighter in colour due to the affects of the sun wind
and rain over the years .Cotec guarantees our roof cleaning system for 3 years. Contact Us quotes are Free and without obligation.

This roof tile would have been 30mm when new but the elements over the years have
worn the surface it is now 27.9mm.
Roof Tile Thickness before cleaning 27.9mm
Roof Tile Thickness after cleaning 27.6mm
(The same thickness as a Smart phone screen protector.)
The loss to the tile surface is .03mm which is comparable to Algoclear Roof Cleaning or
Softwash Roof Cleaning.

Vortex Low Pressure Controlled Volume Roof Cleaning System
VORTEX Nozzle projects a low-pressure swirl of water to clean the roof tile surface gently and effectively without damage to the
substrate. The vortex Cleaning System is specially designed to deliver a constant flow of low pressure spinning water that quickly
breaks down grime and effectively removes moss. A very effective roof cleaning system for the removal of moss lichen and algae.
How does this work?
The pressure washer’s ability to clean depends upon a combination of pressure (measured in PSI) and flow rate (in litres per minute)
both are equally important. The flow rate in litres per minute is a very important measure of the cleaning ability. In general DIY
machines commonly have flow rates as low as 6-8 litres/min whereas commercial units have flow rates varying from 20 to 40 litres a
minute at the same pressure of a domestic machine, double the flow means double the cleaning power. So, by using a lower
pressure but a larger flow rate we can be just as effective if not more than a high-pressure washer.
