Why Choose Us for Mould Treatment in Melville?
South-facing slopes get thick moss and lichen from river humidity, especially with tree shade overhead. This growth holds moisture against tiles, promotes rot, and lifts edges so water gets underneath. We treat moss with a biocide during restoration to kill spores and prevent regrowth. The biocide is included in our standard restoration and keeps moss from returning quickly. Melville's humidity means some regrowth is normal, so regular cleaning every two to three years keeps it in check. We assess whether you need preventative treatment.
Mould on Melville ceilings and dark patches on south-facing tile roofs signal moisture and inadequate ventilation. River humidity and shaded roof areas create damp conditions year-round. Treating mould on roof surfaces means cleaning, biocide application, and improving airflow. Interior mould usually points to roof moisture entry. We assess whether it's a roof leak, ventilation issue, or trapped condensation. Treatment plus root-cause fix stops regrowth.

Benefits of Mould Treatment for Melville 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 Melville
- 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.

My ceiling has mould but I can't see a roof leak. Is it coming from the roof anyway? ▾
Not always. Mould can be condensation from poor ventilation or interior moisture. We assess roof condition and ventilation during inspection. If roof is dry, we recommend ventilation improvements. If wet, we track the leak source.
Is mould treatment something I can do myself or must I hire a professional? ▾
Small surface cleaning you can do. But if mould keeps returning, there's an underlying moisture source. Professional assessment and treatment addresses the cause, not just symptoms. Saves time and stops health risks.
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.
