Why Choose Us for Mould Treatment in Warnbro?
High humidity around 70-74% year-round means mould and moisture issues are real on Warnbro properties. Decades of salt exposure and poor drainage create the perfect environment for mould to grow in roof cavities and under tiles. Once you spot mould, it means water's been sitting in your structure for a while. We identify the moisture source first. Often it's failed pointing, blocked gutters, or deteriorated flashing letting water in. Treating the leak stops new mould forming. For existing mould, we assess the timber condition and recommend either cleaning the affected area or timber replacement if deterioration is severe. Preventative roof work stops mould starting in the first place.
Warnbro's 70-74% humidity year-round combined with 30-40 year old dense tree canopy creates ideal conditions for moss and algae. Many roofs here show 40-60% moss coverage. Established properties have thick, black lichen on south-facing slopes. Treatment kills the moss at the root, not just blasts the surface. Without treatment, regrowth happens within weeks in this environment.

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

How bad is the moss problem on Warnbro roofs? ▾
Severe. High humidity at 70-74% and mature tree shade mean 40-60% moss coverage is normal on older roofs here. The southern slopes stay damp and cold. Moss holds moisture against tiles and lifts them. Treatment first, then cleaning removes the growth properly.
If I treat the moss, will it come back quickly in Warnbro? ▾
Slower than a surface clean alone, but yes, eventually. Warnbro's conditions favour regrowth. A treatment followed by a roof coating or regular maintenance keeps it at bay longer. Beachfront properties need more frequent retreatment due to shade and salt-moisture combination.
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
"The roof restoration really made my home a completely new house. Besides the weather keeping the work delayed nothing else I could fault them. I got a competitive quote, no hidden cost, very professional and the work they have done was fantastic. My neighbours love their work and asked for a quote too. I highly recommend! P.S. I know that the photos seems to be totally different but I recently painted my house and the roof is just the last thing needed to be done. There are things that I needed professional."
"Great company and very reasonably priced. We were referred by our friend that had work done by the team also. Professional and good communication throughout the whole process. Highly recommend this company."
