Roof Washing Brisbane
Moss, lichen and algae don't just look bad — they actively break down your roof tiles and can void your manufacturer warranty. We remove them safely, without high pressure that cracks tiles or strips coatings.
Moss and lichen are slowly destroying your roof
In Brisbane's humid climate, roof surfaces collect moisture and organic matter year-round. Moss, lichen and algae take hold fast — and once established, they work their way under tiles, lifting and cracking them over time.
At Washing Master, we use a soft wash method specifically designed for roofs. A biodegradable treatment kills the growth at the root, and low-pressure rinsing removes it without cracking tiles, stripping Colorbond coatings or forcing water into the roof cavity.
High-pressure cleaning on a roof is one of the most common causes of tile damage in Brisbane. It removes the growth visually but leaves the root behind — and the pressure itself can crack older terracotta tiles or strip granules from concrete tiles.
What's growing on your roof
Moss
Holds moisture against the tile surface, accelerating breakdown and causing tiles to lift. Common on shaded or north-facing roofs in Brisbane.
Lichen
Bonds chemically to the tile surface and requires a treatment solution to break the bond. Impossible to remove safely with pressure alone.
Algae & black streaks
Spreads rapidly in humid conditions and causes the dark streaking commonly seen on Brisbane roofs. Makes a roof look 10 years older overnight.
General debris buildup
Leaves, dirt and organic matter trapped in valleys and gutters accelerate moisture damage and block drainage, leading to leaks.
Our 4-step process
Same structured approach on every roof — tile, concrete, terracotta or Colorbond.
Roof inspection
We assess roof type, pitch, extent of moss and lichen, condition of tiles or Colorbond, and any areas of existing damage that need to be noted before we start.
Biodegradable treatment application
A specialist roof cleaning solution is applied to kill moss, lichen and algae at the root. The solution is safe for all roof types and surrounding garden areas.
Low-pressure rinse
We rinse using low pressure only — enough to remove the dead growth without cracking tiles, stripping coatings or forcing water into the roof cavity.
Gutters and valleys cleared
We clear debris from gutters and roof valleys as part of the job, so drainage is restored and nothing is left to hold moisture against the surface.
How much does roof washing cost in Brisbane?
Pricing depends on roof size, pitch, roof type and level of moss or lichen buildup. Heavily affected roofs take more solution and time — we'll give you a fixed price upfront so there are no surprises.
Final price depends on:
- Roof size and pitch
- Roof type (tile, Colorbond, terracotta)
- Extent of moss, lichen and algae
- Gutter and valley condition

Gutters cleared as standard. We don't leave debris in the gutters — drainage is restored as part of every roof wash.
