Kill It at the Root
Roof Moss & Mould Treatment, Auckland-Wide
Targeted treatment that kills moss, mould and lichen at the root — then keeps working for months so it doesn’t come back.
Overview
Stop Moss and Mould Before They Damage Your Roof
Moss and lichen don’t just look bad — their root systems work into tile surfaces and under laps in steel roofing, holding moisture against the roof and accelerating wear. Left alone, they shorten roof life and can void coating warranties.
Our treatment is applied dry and left to work: it kills moss, mould and lichen at the root, then weathers off gradually over the following months. It’s the lowest-impact way to bring a roof back — no blasting, no foot-traffic damage — and the results keep improving for up to a year after application.

Auckland Service Guide
Professional Roof Moss Spray and Moss Treatment
A professional roof moss spray is a controlled moss, mould and lichen treatment—not ordinary high-pressure roof blasting. We inspect the roof material and growth level first, then apply a suitable treatment and explain the expected weathering period before quoting the work.
Results are progressive: algae and mould react sooner, while thicker moss and lichen can take months to weather away. We set expectations for the roof condition rather than promising an instant result from a treatment service.

How It Works
Our Simple 4-Step Process
Roof Inspection & Quote
We check growth levels and roof condition, and confirm treatment is the right approach.
Careful Application
Treatment is applied evenly across the roof from safe access points.
Let It Work
The treatment kills growth at the root; dead moss and lichen weather off naturally over following months.
Follow-Up Check
We check back on the result and recommend a re-treatment cycle to keep the roof clear.

Common Questions
A wash physically removes grime and growth immediately; treatment is a no-pressure chemical application that kills growth at the root and lets it weather away naturally. Treatment is ideal for fragile roofs or as follow-up protection after a wash.
Mould and algae start dying within days, while thick moss and lichen brown off and weather away over 2–6 months depending on rain and growth thickness. The roof keeps improving for up to a year.
Most roofs stay clear for 2–4 years. We recommend a re-treatment cycle so growth never re-establishes.
We use products responsibly and take care around gardens. If you collect drinking water from your roof, tell us when booking — we’ll disconnect downpipes and advise when it’s safe to reconnect.
