Short answer
As a guide, a professional roof clean on a single storey Brisbane home starts from about $660, and a two storey home starts from about $770. The final price depends on the roof's size, pitch, access, how much lichen and mould has built up, and whether solar panels or skylights need working around. A free on-site or photo quote confirms the exact figure.
Key points
- Single storey roofs start from $660 and two storey roofs from $770 (Waterworx prices, October 2026).
- Size, pitch, access and heavy lichen move the price more than the roof material does.
- Soft washing suits most tile and metal roofs; high pressure can damage some tiles.
- Cleaning is not restoration: cracked tiles, failed pointing and worn coatings are a separate job.
- Seniors Card holders get 10% off with Waterworx.

What pushes a roof cleaning quote up or down
| Factor | Why it matters |
|---|---|
| Roof size | More area means more treatment product and more time on the roof. |
| Pitch and height | Steep or two storey roofs need extra safety gear and slower, careful work. |
| Lichen and mould build-up | Heavy growth can need a longer dwell time or a second treatment. |
| Access | Tight side paths, big drops or no truck access add set-up time. |
| Solar panels, skylights and aerials | Each one has to be worked around, and panels need gentle care. |
| Roof material | Tile and metal cost about the same to soft wash; fragile or very old tiles need extra care. |

Tile vs Colorbond: is one cheaper to clean?
In practice the material makes less difference to the price than size and access. Both are usually soft washed: a low pressure clean using a treatment that kills mould and lichen at the root, then a gentle rinse.
- Concrete and terracotta tiles: high pressure can strip the surface and shorten the tile's life, which is why some manufacturers advise against pressure washing.
- Colorbond and other metal roofs: dirt and mould wash off easily, but the coating needs a product the manufacturer approves.
Does your roof need a clean or a restoration?
A clean removes dirt, mould, moss and lichen. It does not fix broken tiles, cracked ridge capping, failed pointing or a faded, chalky coating. Those are restoration jobs, which cost several times more.
If a roof is only dirty and stained, a clean is usually all it needs and can add years before a restoration is due. If we find damage during the quote, we will tell you before any work starts.
How often should a Brisbane roof be cleaned?
Most Brisbane roofs benefit from a clean every two to four years. Roofs under trees, on the shady south side or close to the bay grow lichen faster and may need it sooner.
A clean is also worth doing before selling, before solar panels go on, or before a roof is painted, because coatings will not bond to a dirty surface.
