Why Choose Us for Mould Treatment in Scarborough?
The humidity in Scarborough, sitting at 70 to 75 percent most of the time, breeds mould in the shaded pockets on your north face. Tile roofs up here almost always have some growth on the cool side, and metal roofs can trap moisture underneath if they're not properly ventilated. We clean it off with appropriate treatments and pressure, then assess whether ventilation or drainage is the real problem. Mould itself doesn't usually damage the roof, but it's a sign moisture's getting trapped somewhere. We treat it, then identify why it's there so it doesn't come back in six months. Sometimes it's a blocked gutter, sometimes it's a valley running moisture the wrong way. Most Scarborough homes need annual or biannual cleaning to keep mould under control.
Scarborough's humidity (70 to 75%) and coastal winds create perfect mould conditions on north-facing roof areas. Shaded spots collect moisture and grow mould fast. We treat it with biocide and ensure the roof is clean and dry before any coating. If your north side has green or black patches, mould is probably the reason.

Benefits of Mould Treatment for Scarborough 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 Scarborough
- 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 Scarborough - FAQs

Does mould come back quickly after treatment in Scarborough? ▾
If the roof stays clean and dry, no. We use biocide that keeps mould off for years. But if your gutters block, water pools, and the area stays damp, mould can return within 12 months. Gutter cleaning and roof maintenance prevent it coming back.
Can I just paint over mould on my Scarborough roof? ▾
No, it won't stick and mould will eat through the paint. We remove the mould first with biocide, clean the area, dry it completely, then apply a protective coating. Skipping the treatment means wasting time and money on paint that peels off.
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.
