Why Choose Us for Mould Treatment in Como?
Como's riverside location and persistent October to May fog create sustained moisture that mould loves. Shaded areas under the tree canopy stay damp constantly. Mould accelerates roof breakdown and causes health issues inside. Dark patches on ceilings or under eaves mean mould is growing on the underside of the roof. We treat it with biocide that kills growth and stops spores. But the real solution is getting moisture out, so we recommend ventilation and gutter clearing. Mould treatment is often part of a larger cleaning job where we also address moss that traps moisture.
Mould growth in Como appears primarily in gutters, roof cavities, and fascias rather than on exposed tile. River humidity and blocked gutters create the perfect breeding ground. If you notice black spots on fascias or in gutters, or a musty smell in the roof space during wet weather, mould is likely present. The issue ties directly to moisture management, keeping gutters clear and roof cavities ventilated prevents the damp conditions that allow mould to thrive.

Benefits of Mould Treatment for Como 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 Como
- 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.

I see black spots appearing on my Como home's gutters and fascias. Is that mould? ▾
Likely yes. Como's river humidity and leaf debris in blocked gutters create ideal mould conditions. Don't ignore it, mould spreads and can penetrate into roof cavities. Clean gutters quarterly, ensure roof ventilation is unobstructed, and have the affected areas treated to prevent structural damage and health risks.
How do you treat mould on Como roofs? ▾
Treatment depends on severity. Light mould responds to pressure cleaning and biocide application. Heavy mould growth in gutters or cavities may require gutter replacement or fascia repainting with mould-resistant products. Prevention, regular gutter cleaning and maintaining dry roof spaces, is more effective than repeated treatments.
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.
