Roof treatments Auckland
Treat the moss now. Let time and weather do the rest.
Moss, mould or lichen taking hold? Roof treatment is the gradual option. We assess the roof first, apply a suitable treatment where appropriate and explain why the change is not immediate.

A different way to clean a roof
For moss, mould and lichen that can be treated gradually.
A roof treatment is applied to suitable organic growth and left to work progressively. It is often the better option when an immediate physical wash is unnecessary or would be too aggressive for the roof.
Roof type, coating, pitch, access and the amount of moss, mould or lichen all affect the recommendation. We explain the process in plain language before you choose it.
Before treatment is recommended
What we check—and what you should expect.
The free site visit is used to decide whether treatment suits the roof and to set realistic expectations about the gradual change.
Good to know
Roof treatment takes time. We will tell you what to expect.
Treatment works with time and weather exposure. The roof will not look freshly washed on the day of application, and stubborn growth may take longer to release than light surface growth.
We will not promise a generic timeframe before seeing the roof. We explain what is reasonable for its material, condition, growth and exposure.
Before we recommend treatment, we consider:
That assessment determines the application plan and the expectations we set with you.
- Tile, metal or other roof material
- Age, coating and visible surface condition
- Type and density of moss, mould or lichen
- Pitch, access, weather and nearby property areas

What happens next
The questions people ask after hearing “gradual”.
How quickly will a roof treatment work?
Not immediately. The treatment works progressively, and the timing varies with the growth, roof surface, weather and exposure. We explain the likely progression after the assessment.
Is roof treatment the same as roof washing?
No. Treatment is a gradual process for suitable organic growth. Washing is a more immediate physical clean for roof surfaces that can be safely washed.
Does the roof need to be walked on?
Not necessarily. The access plan depends on the roof, pitch and property layout, and is decided before the scope is confirmed.
Can I combine a roof treatment with gutter cleaning?
Yes. We can inspect both during the same visit and list them separately so the timing and inclusions stay clear.
While we’re looking up
If the gutters or roof surface also need attention, show us during the same visit.
Show us the roof. We’ll recommend the right route.
