are our 2 Top Rated Products to Clean Your Roof

Roof Cleaning with either Wet & Forget or Rapid Application will not damage your roof in any way, as they are non-caustic, non acidic and contain no bleach!   

Rapid Application contains no bleach
Chlorine Bleach Products (or Sodium Hypo Chlorite) are a NO! NO!

It is wise to avoid chlorine bleach as a roof cleaner. Chlorine bleach can remove the natural colour from any wood shingles.  It can also kill the lower level vegetation if it runs onto the ground as it is rinsed from the roof.  It can also accelerate corrosion of metal guttering and spouting systems

For us here in NZ, the south side of the house always get the worst deal as it sees so little sunshine in the winter and these surfaces stays damp over a long period of time – a heavenly breeding ground for moss, mould and lichen. Don’t let the moss, mould, lichen and algae organisms damage your roof by ignoring the problem and thinking that it will just go away. It will categorically shorten the lifespan of the roof.

Moss On Your Roof - Removing Moss off Your Roof!
Moss and algae accumulate on all roofs. Those places that receive more rainfall and have sustained high levels of humidity have more moss and algae growth as the moss and algae need water to grow and multiply. The thick moss growth with its shallow root system keeps the roofing materials damp for extended periods of time and this moisture promotes wood rot and can and does erode areas like the asphalt in shingles.

Green Algae on Your Roof - Removing Green Algae off Your Roof 
Green algae is not harmful to the actual roofing material because it does not develop roots but does hold more moisture which is a perfect condition for other biological growths to develop. This growth is more of an aesthetic issue since it makes the roof look horrible and hides the original roof colour. This algae can be cleaned from the roof. 

Black Fungi on Your Roof - Removing Black Fungi Off Your Roof
Is often confused for dirt and general grime as this is what it looks like but in fact it is a biological growth and once treated with Wet & Forget's products, the black fungi will be dead and will gradually and gently weather away with the weathering process of rain and wind.  This is a gradual process and initially it appears that nothing has happened. Have patience! Good things take time!

Your best options for roof cleaning without damaging your roof are 'Wet & Forget' or 'Rapid Application'.

For The Best Results to Clean Your Roof:
for Moss Removal / Black Fungi Removal 

  • Apply to a cool roof surface, preferably on an overcast day. This will keep the roof surface wet with the solution for longer. The solution also helps to loosen the grip of the shallow moss roots.
  • Make sure the surface is dry in order to get the best penetration of the growth with the least amount of evaporation.
  • Total saturation of the surface with this product is essential in order to obtain a good kill of the fungi, algae, lichen, moss & algae which infests these surfaces.
  • If the surface is particularly bad, do another application approximately one month from the first application.
  • Then allow the surface to weather naturally and nature will take its course. The growth decomposes while the rain gently removes it from the surface over time. Let Mother Nature do her thing!
  • After 1st application use as a maintenance tool. 
    Only re-apply at the first sign of regrowth.  Lichen Removal (See Below)
