Why Choose Us for Mould Treatment in Leederville?
Dense mature gardens on small lots mean shade covers plenty of Leederville roofs. Moss colonies grow thick in those shaded areas, especially on the south-facing slopes where winter sun barely reaches the tiles. We treat moss and slow regrowth as part of a regular maintenance plan. Clean it off, apply treatment, and you get 12 to 18 months before it gets heavy again. On heritage tiles, we're careful with pressure and chemicals so the glaze stays intact.
Leederville's mature tree coverage and dense gardens create persistent shade where moss and black mould thrive on shaded slopes and valley areas. Mould treatment kills the growth and slows regrowth, but without fixing the underlying cause (shade or poor drainage), it returns. We treat and address drainage or gutter issues driving the mould so results last longer.

Benefits of Mould Treatment for Leederville 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 Leederville
- 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 black mould on my roof dangerous to my family? ▾
The mould on your roof is outdoor growth, not toxic indoor mould from damp bathrooms. It doesn't spread spores inside your home. But it holds moisture, accelerates coating breakdown, and looks bad. Treatment followed by gutter cleaning stops it returning for years.
My roof gets moss back within a year. What actually stops it? ▾
Shade is usually the cause. Thinning overhanging tree branches helps significantly. We treat moss chemically and it stays gone 2 to 3 years, but heavy shade means faster regrowth. Combined treatment plus gutter maintenance gives longest gaps between 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.
What Our Customers Say
"Carlo Poli gave Roof Restorers Perth 5 stars."
"Roof Restorers Perth - Ryan - was very professional, and on time. He worked very hard, and cleaned up after himself to the delight of my husband. The results speak for themselves, and in fact, a neighbour who was passing by commented on how good the roof looked after Ryan had finished. I highly recommend him."
