Professional Tiled Roof Treatment
The Safe Alternative to Pressure Cleaning

Tiled roofs across Perth develop moss, lichen, mould and mildew. Left unchecked, they trap moisture, damage tiles and lead to expensive repairs down the track.

Our biocide treatment kills organic growth safely and effectively. We apply a professional-grade solution that penetrates deep into porous tiles, kills the growth at its source, and continues to inhibit regrowth for years.

Within 1–2 weeks, the growth dies off. Over the following 3–12 months, it naturally weathers away with rain and exposure.

FAQ

How does the biocide treatment work?

We apply a professional-grade biocide solution directly to your roof tiles. It penetrates the porous surface and kills moss, lichen, algae, mould and mildew at the root. The growth dies within 1–2 weeks and naturally weathers away over 3–12 months.

Is this safer than pressure cleaning my tiled roof?

Yes. Pressure cleaning can force water under tiles, crack them, damage ridge capping, and disturb pointing. Our treatment uses no pressure, eliminating these risks entirely.

How long does the treatment last?

The biocide continues to inhibit regrowth long after application. in most cases it will protect against moss, lichen and algae regrowth under normal environmental conditions for 12+ months.

Will you need to walk on my roof?

In most cases, no. We can apply the treatment without walking on your tiles at all, which reduces the risk of accidental damage.

How much does it cost?

Starting at $800 for a standard residential tiled roof. This includes application of a professional-grade biocide providing long-term protection. No hidden extras.

Is this treatment suitable for all tiled roofs?

It’s ideal for older roofs, roofs with visible moss or lichen build-up, and roofs where pressure cleaning would pose a risk. We’ll inspect your roof and confirm if this service is right for you.
