Why Choose Us for Mould Treatment in Karrinyup?
Thick shade from Karrinyup's mature trees creates a damp environment on many roofs, and once moss and lichen take hold, they retain moisture and encourage mould growth underneath. Mould weakens tile binding and accelerates mortar breakdown, turning a shade problem into a structural one if left unchecked. We treat active mould using solutions that kill spores without damaging tile or mortar, then improve water drainage so conditions don't encourage regrowth. After treatment, the key is preventing mould returning, which means regular gutter cleaning to stop debris dams and clearing overhanging branches where possible. A north or south-facing elevation shaded by large trees will regrow moss and mould fairly quickly in Karrinyup's humid climate, so treatment is part of an ongoing maintenance rhythm rather than a one-time fix. We often combine mould treatment with a high-pressure clean to remove the visible growth and check for any damage the moisture has caused to mortar or tile underneath.
Karrinyup's shade and moisture create ideal conditions for moss, lichen, and mould growth across roof surfaces. Black spots on tiles are usually mould or lichen, not dirt. These hold moisture and accelerate tile deterioration. Treatment includes a high-pressure clean and a biocide application that kills spores. Results last longer if gutters stay clear and trees are trimmed to increase airflow.

Benefits of Mould Treatment for Karrinyup 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 Karrinyup
- 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 just dirt or is it mould? ▾
Usually it's mould or lichen, especially on north-facing or shaded sections. Dirt washes off with water. Mould requires chemical treatment. If you're not sure, a photo sent to us settles it in seconds.
Will mould come back after treatment? ▾
Not immediately. Biocide treatment lasts 12 to 24 months in normal conditions. Keeping gutters clear and trimming overhanging branches slows regrowth. A full roof restoration with quality coating reduces regrowth significantly.
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.
