Why Choose Us for Mould Treatment in Kelmscott?

Kelmscott's river corridor creates higher humidity that promotes mould on aging mortar, particularly on shaded roof sides where the Canning River mist doesn't burn off until midday. Mould colonies weaken mortar and trap moisture against tiles, speeding up deterioration. We treat mould with a biocide that kills colonies below the surface, not just visible growth. It works best after a high-pressure clean, and it stops mould coming back quickly on those persistently damp sections under big trees throughout Kelmscott.

Mould grows aggressively on Kelmscott roofs, especially in shaded areas under mature trees in both river corridor and foothills. Ambient humidity from the Canning River and moisture trapped under heavy canopy create perfect mould conditions. Black mould on concrete tiles or Colorbond doesn't just look bad, it indicates water and moisture problems underneath. Treating surface mould without addressing the moisture source means it comes back. Quarterly gutter cleaning and biocide treatment, usually 500 to 900 per application, keeps mould down long-term.

Benefits of Mould Treatment for Kelmscott 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 Kelmscott

  1. 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. 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. 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. 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 actually mould?

It's mould or lichen. Both grow when moisture sits on the roof, which happens under heavy tree cover. It's not just cosmetic, it spreads and holds moisture against the surface, leading to rot in tiles or rust on metal. A biocide treatment kills it, but you need to address the moisture cause, gutters clearing, canopy management, or improved drainage, otherwise it comes back.

How much is biocide treatment for mould on a Kelmscott roof?

Around 500 to 900 per application depending on roof size and mould severity. Most people in heavily shaded areas repeat it every 6 to 12 months. If you're in the river corridor with high humidity or under heavy foothills eucalyptus, plan on regular treatments. Without addressing the moisture source though, you're fighting a losing battle long-term.

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.
