Why Choose Us for Mould Treatment in Serpentine?
Serpentine Falls and the zones near the Serpentine River stay humid longer because of the water nearby. Moss and mould build up fast on south-facing roof sections that don't get much direct sun. A biocide treatment kills the moss and mould right now, and then a good coat seals the surface so it doesn't come back as quick. We spray the biocide, let it work for a few days, then clean the roof again. If you're seeing black or green stains on your tiles or metal, mould treatment costs $800 to $1,400. It's often part of a full restoration, but if your roof just needs freshening, treatment alone can buy you two to three more years before a full coat.
South-facing roof sections under Serpentine's dense canopy stay wet longer, creating ideal conditions for mould and moss. The jarrah forest canopy blocks sun and traps morning dew. We treat mould with biocide chemicals that kill organic growth at the root, then apply a protective coating with algae inhibitors built in. Treating mould early stops it from damaging tile glazes and metal coatings over time.

Benefits of Mould Treatment for Serpentine 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 Serpentine
- 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.

Can I just hose off mould and moss myself in Serpentine? ▾
You can try, but it often comes back quickly. Just spraying water doesn't kill the roots. Professional treatment uses biocide that penetrates and prevents regrowth for years, not weeks.
Why is there so much moss on my roof in Serpentine? ▾
The jarrah and marri canopy blocks sun and holds moisture. South-facing sections barely see daylight. That combination of shade and damp is paradise for moss. It's not a sign of a bad roof, it's just the local environment.
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
"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."
"Ryan was very responsive to all my messages, came out and gave us a quote to have a full roof restoration. They showed up on time every day, kept me in the loop with what they were doing and what was to come the next day. They cleaned up the mess and on top of all that, that roof looks fantastic! Looks brand new ! I would highly recommend these guys. Thanks so much for all your hard work and a fantastic job."
