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 Sydney
Roof cleaning in Sydney is costed by the roof area, the pitch and access, and the cleaning method, because cleaning a roof means removing moss, 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-access roof treated and sealed costs more, so the area, the pitch and the method drive the price.
Sydney's eastern-suburbs and inner homes often have steep tile roofs where moss and lichen build up on the shaded southern pitches, and a terrace's height and tight access can lift the cost. The city's highest trade rates apply, and working at height on a steep roof needs height-safety gear. The salt air near the coast leaves a grime film on a seaward roof. A soft wash suits a fragile or old tile roof better than a harsh pressure clean. Roof cleaning is an exterior cleaning service rather than a licensed building trade, so no licence is required, though any repair to the metal roofing or flashing is a licensed roof plumber's work, in Sydney.
