Why Choose Us for Mould Treatment in Shelley?
The Canning River creates a moisture bowl over Shelley, and mould follows moisture. When organic growth appears inside your roof space, on beams, or in boxed soffits, it's a sign the ventilation isn't keeping up with the humidity. Mould treatment is about killing the growth, but the real fix is stopping it coming back. We treat visible mould with biocide, then assess your ventilation and roof surface condition. Often the answer is improving air circulation or addressing underlying moisture problems like blocked gutters or failed flashing. In a riverside suburb, you can't just spray and hope. You have to fix the root cause or mould returns within a year.
Mould thrives on Shelley roofs because of the humidity bowl effect created by the Canning River's two-sided proximity. Shaded slopes facing south and east hold moisture longer. Paperbark and gum trees further block air circulation. Mould isn't just cosmetic. It can break down tile surface over time and contributes to water penetration. Biocide treatment kills the spores at substrate level.

Benefits of Mould Treatment for Shelley Properties
Kills it, not just hides it
We treat the moss, lichen, algae and fungus so it dies off at the root, then remove it, rather than just blasting the surface and leaving spores behind to grow straight back.
Protects the roof
Moss and lichen hold moisture against the tiles and work into the pointing. Treating it stops it lifting tiles and breaking down the roof from the surface.
Slows regrowth
A proper treatment leaves the roof clean for far longer than a plain wash, especially on the shaded, damp slopes where growth takes hold first.
Tile and metal roofs
We treat tiled and metal roofs alike, at the right pressure for the surface so the roof isn't damaged in the process.
Our Mould Treatment Process in Shelley
- 1
Assess the growth
We check how heavy the moss, lichen and mould is and where it's worst, usually the shaded southern slopes, and quote a fixed price.
Why it matters: The treatment is matched to how established the growth is.
- 2
Apply treatment
A treatment is applied to kill the moss, lichen, algae and fungus at the root across the affected roof.
Why it matters: Killing it first means it lifts cleanly and doesn't regrow from leftover spores.
- 3
Remove and rinse
The dead growth is cleared off and the roof rinsed down at a pressure suited to the surface.
Why it matters: Clearing the dead material leaves the roof clean and the tiles visible.
- 4
Check the roof
With the roof clean, we point out any cracked tiles, failed pointing or other wear the growth was hiding.
Why it matters: Moss often hides the faults underneath it.

Is the black stuff on my roof mould or just dirt? ▾
Likely both, but mostly mould and lichen. Shelley's humidity supports aggressive growth. If it's only on shaded slopes, that's classic humidity-driven mould. Professional cleaning and biocide treatment kills the spores and slows regrowth, though mould returns faster in Shelley than in suburbs further from the river.
Will mould treatment stop it coming back? ▾
Biocide treatment kills existing spores and provides residual protection, but Shelley's moisture-rich environment means regrowth happens faster here. Expect to need professional treatment every 3 to 4 years depending on tree coverage. Regular gutter cleaning and trimming overhanging branches also helps slow regrowth.
How much does roof mould treatment cost in Perth? ▾
It depends on the roof size and how heavy the growth is. Call 08 6388 4492 or request a quote for a fixed price. If you're treating ahead of a paint or restoration, we roll it into the overall job.
What's the difference between mould treatment and a roof clean? ▾
A clean blasts the surface. A treatment kills the moss, lichen and fungus at the root first so it dies off and is far slower to come back. For heavy organic growth, treatment lasts much longer than a wash alone.
Does the moss and mould come back? ▾
Not as fast after a proper treatment. It can return over time in shaded, damp spots, and a roof coating slows it further. A surface-only clean that leaves spores behind grows back within weeks.
Is it safe for my roof and garden? ▾
We treat at the right strength and pressure for the roof type so the surface isn't damaged, and we take care around gardens and downpipes when rinsing off.
Do I need treatment, cleaning, or a full restoration? ▾
Heavy organic growth needs treatment to kill it properly. If the roof's just dirty, a clean does it. If it's also faded with failed pointing, that's a restoration. We'll tell you which after a look.
