Moss & Mould Treatment


Unsightly moss and mould on your roof’s surface is not just an aesthetic issue – over time it will cause decay to the coating on your roofing material.
This is the reason most roof paint manufacturers will require a yearly moss and mould treatment to uphold the warranty, it preserves the integrity of the coating.
You must never water blast your roof to remove moss as it may remove it’s precious coating, so slow-acting treatments are the perfect alternative.
The treatment we use is gentle, biodegradable, and environmentally friendly so you need not worry we are spraying harsh chemicals near your pets and family.
Our treatment is sprayed on a dry roof and left without rinsing. It then activates by targeting just the moss spores and killing it at the source and after up to 4 months the moss will have washed away naturally with the rain.
The treatment remains on your roof surface and can prevent the moss and mould from returning for years!Moss and mould treatments are recommended to be applied once a year to ensure your roof’s surface remains in peak condition.
We can also apply the treatment to your wall cladding, fences and paths to prevent slipping and keep your family safe.
If you are planning to sell your home, this is a simple and cost-effective solution to your moss problem which can dramatically elevate your home’s appearance. Moss and mould are unsightly and could be scaring off your potential buyers or tenants!

“I am very happy with the work and communication with Phil and his Rimu Roof team. He submitted an initial quote that I asked for him to expand for comparison with other quotes. I felt confident with Phil’s experience with tile roofs and his explanation of the repair. He completed the task in the number of projected days and communicated when the rain interfered. The work comes with a guarantee, which I appreciate. Phil and his team are “good people” as well as competent, which is always a plus.”
