High pressure can strip the protective coating off old painted or fragile tiles and force water under them, soft washing is gentler and safer on tile roofs. Match the method to the roof.
Roof cleaning improves appearance and removes moss and lichen that hold moisture. Match the method to the roof, soft wash for fragile or painted tiles, pressure wash for sound metal and concrete. It is also the right time to check ridge caps.
Ways to save
- Do gutters at the same time, the access is already set up.
- Soft washing is gentler on old tiles and avoids the damage aggressive pressure washing can cause.
- If the roof is being cleaned for sale, a wash is far cheaper than a full restoration and often enough.
How we estimate this
Roof cleaning in Australia typically costs around $400 to $800 for an average home in 2026, with large or two-storey roofs and soft-wash treatments higher. Re-pointing ridge caps and sealing are separate, larger jobs.

What a roof cleaning costs in Darwin
Roof cleaning in Darwin is priced on the roof area, the pitch and access, and the cleaning method, since cleaning a roof means removing mould, lichen, dirt and grime by a low-pressure soft wash or a pressure clean, often with a treatment, so the area and the access lead the figure. A simple single-storey wash is cheaper, while a steep, high or hard-to-reach roof treated and sealed costs more. Labour among the highest in the country lifts the clean.
The tropical wet season drives mould and lichen on a Darwin roof, because the extreme humidity and the monsoon rains feed fast growth on a metal or tile roof, and the storms leave debris and grime. A cyclone-rated metal roof is near-universal here, and a soft wash with a treatment clears the mould and rinses the salt-tinged coastal grime. Working at height needs height-safety gear, more so in the heat. The remoteness has no bearing on a local cleaning service. Roof cleaning is an exterior cleaning service rather than a licensed building trade, so no licence is required, though any repair to the roofing or flashing is a licensed roof plumber's work, in the Northern Territory.
Roof cleaning is an exterior cleaning service rather than a licensed building trade, so no building licence applies, though roof plumbing repairs the metal roof, gutters or flashing and a roof tiler the tiles, in the Northern Territory under NT Building Practitioners licensing for the building side. For a Darwin home, the clearest way to price roof cleaning is by the roof area, the pitch and access, and the method, with wet-season mould and storm grime the load.
