Commercial Moss & Mould Treatment Auckland

A roof treatment is typically the best choice when your roof has biomass growth such as moss, mould, lichen and algae. North Shore House Wash experts use Benzalkonium Chloride chemical which is a natural eco friendly outdoor cleaning product. Our treatmnets are salt based which penetrate your roof and into the biomass and its roots.

The moss, mould and lichen treatment is left on the roof and over a 4 – 6 week period will kill off biomass growth. Over the next 6-12 months the rain, wind and sun will weather away the dead biomass leaving your commercial roof moss free. This process can prevent biomass regrowth for up to 2 years or sometimes longer.

This is often the best option to tackle a very dirty roofs and fragile old roofs which may ultimately don’t need the medium pressure roof washing.

Once the roof has been treated for moss, mould and lichen growth and left for a year any residual growth can be re-sprayed or pressure-washed off ensuring a much easier, delicate job now that the growth is dead and will come off easily from your roof’s surface.

Our commercial moss, mould and lichen treatment will add life to your roof by removing biomass growth.
