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 Perth
Roof cleaning in Perth is priced on the roof area, the pitch and access, and the cleaning method, since cleaning a roof means removing dirt, grime, lichen and dust 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, so the area, the pitch and the method drive the price.
Perth's hot, dry Mediterranean climate bakes grime and fine dust onto a roof over the long summers, and the dust carried on the summer winds is the usual load rather than the heavy moss of the wetter cities. A double-brick home's tile roof is common, and a soft wash lifts the grime without cracking a sun-brittle tile. The cooler, wetter winters can bring some lichen to a shaded pitch. Working at height needs height-safety gear. The isolation of the WA market 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 Western Australia.
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 Western Australia under WA Building Services for the building side. For a Perth home, the clearest way to price roof cleaning is by the roof area, the pitch and access, and the method, with sun-baked grime and dust the usual load.
