Why Choose Us for Mould Treatment in Armadale?
Shaded areas of your roof, the south and west sides where big trees block the sun, are perfect for mould and lichen growth in Armadale's humid summers. Moss creeps under tiles, retains moisture, and speeds up mortar breakdown. We don't just scrub it off and leave it. Our biocide treatment kills the mould at source and prevents rapid regrowth. We do this as part of a full roof cleaning using 4500psi pressure to shift decades of heat-baked grime, then apply the treatment to problem areas. It's an important step in any restoration work in Armadale's climate.
Armadale's established gardens create micro-climates where north and west faces cop extreme heat while south and east sides stay shaded by mature trees. This creates perfect mould and moss conditions on shaded sections. Mould grows in moisture trapped under loosened tiles and in shadowed valleys. Treatment requires identifying both the moisture source, usually failing mortar letting water sit, and the shade condition causing slow drying.

Benefits of Mould Treatment for Armadale 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 Armadale
- 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.
Mould Treatment in Armadale - FAQs
Do you provide mould treatment in Armadale? ▾

Why is there black mould only on the south side of my Armadale roof? ▾
That side stays shaded by trees while staying damp from morning moisture or roof leaks. Mould loves shade and moisture. Fixing the leak source and treating the mould stops regrowth, but the real fix is addressing what's letting water sit there.
Is mould treatment safe for my native plantings around the house? ▾
Professional biocide treatment uses products safe for native gardens when applied correctly. We keep spray away from garden beds and use low-toxicity solutions. Most Armadale properties have significant tree coverage we work around carefully.
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.
