Kowhai Roof Treatment Service with Optional Water Wash

Our trained applicators will visit your home and apply the Mosskill treatment to your roof. One treatment is all that is needed to kill all moulds, algae, moss and lichens. The weather will do the rest and will clean up your roof over the following months.

For quicker results we can high pressure wash and clean your roof after one month following the Mosskill treatment.
