This is a very popular service we offer.
Over time, a roof can be host to excess moss which looks un-sightly.
It can also be very frustrating when the moss falls into gutters and blocking them as well as falling to the ground and making a mess.
RJS Cleaning can remove the moss by scraping the roof tiles. However, over time, moss will return so we suggest a chemical clean to vastly extend the time new moss will grow.
Power washing a roof
Though many companies will pressure wash a roof and remove all the moss, dirt and mildew and give instant results, Hypoforce prefer not to use this method.
Pressure washing a roof can lead to damage to roof tiles and also can remove the surface layer of tiles reducing their life span.
Pressure washing on a roof is a messy business too. A lot of the moss and dirt is thrown into the air and can land several meters away from the property. This is very unwelcome by neighbouring houses.
To get the best results, RJS prefer to Softwash
Softwash a roof
Softwashing is by far the safest solution for cleaning a roof.
Using a chlorine based sodium solution and industrial grade detergent, the roof is soaked with the cleaning solution and then rinsed.
Softwash has many benefits. It’s applied at low pressure so no physical damage to the tiles. The chlorine will kill all the moss, lichen, mildew and algae. The detergent then lifts all the dirt and debris off the tiles and is washed away during the rinsing process.
On porous tiles, some of the sodium is left behind and this helps prevent moss and algae growing back over an extended time.
It will take years for lichen to be seen to grow back .
Best time to wash a roof
A roof can be washed anytime of year.
However, for safety reasons, roof washing should not be done on windy days, in the rain or freezing temperatures.
The best time to clean a roof is on calm, cloudy days.
