Our guys will use a fall arrest system with harnesses and strops to wash the roof. They are fully trained at Working at Heights and using the fall rest systems.
When they wash the roof they will apply an industrial-strength washdown product that helps to loosen the mould, lichen and grime and gives a much better end result. A lot of the products available for this sort of work are diluted and so do not produce the end result our product does.
After the wash is completed, we will apply a complimentary slow-release agent which will keep mould, lichen and moss away for longer.
We recommend an annual or biennially treatment after a wash to keep it from growing lichen, mould and getting dirty. This also lengthens the life of the products. Some roofs only need to be done every 3 years it just depends on environmental factors.
As a general rule, we don’t recommend water blasting tiles as they are often loose and water blasting can blow them off the roof which breaks them. The gentlest and cheapest option to get your roof clean is a roof treatment.
As a general rule, we don’t recommend water blasting pressed metal tiled roofs as they are susceptible to denting when incorrectly walked on. They can also be slippery and dangerous. The gentlest and cheapest option to get your roof clean is a roof treatment.
Our approach to cleaning clearlights is to apply our washdown product, followed by a soft wash. Lastly, we apply a slow-release product that works overtime to keep cleaning them. If the clear lights are old, unfortunately, mould gets embedded into the fibre and we are not able to remove this so often they can be far from perfect. Any mould that is sitting on the surface should clean up nicely.
If you are getting your roof painted, then it will need to be washed.
If you’re wanting your roof cleaned instantly and are not wanting to wait 12 months (sometimes this can be more like 6 months) then getting a roof wash would be the better option for you
If you have quite a lot of black mould. A roof treatment is not always that effective on black mould.
