IS YOUR ROOF
GREEN
WITH MOSS &
LICHEN?

No. We never pressure wash roofs. We apply a professional-grade biocide by hand that kills moss and lichen at the root, without the water pressure that can crack tiles or force water under flashings.

Bleach soft washing kills moss and algae on contact and gives an instant white, clean look — but that effect disappears as soon as it's rinsed away, so most bleach-washed roofs need cleaning again within 2–3 years. Our biocide treatment works more slowly: it soaks into the tile and kills growth at the root, then keeps protecting the roof through future rainfall, which is why it typically holds for 3–5 years. It's also gentler on flashing, gutters and surrounding gardens than bleach.

The treatment kills the growth at the root straight away — think of it like spraying a weed instead of pulling it — but the visual clean-up happens gradually as it rains over the following weeks, as the dead moss and lichen rinses away naturally rather than being blasted off.

Every roof treatment includes moss prevention as standard, which protects against regrowth for 3–5 years. Exact timing before any new growth appears still depends on shade, rainfall and roof material.

No. Most jobs can be completed while you're at work — we send before and after photos either way.

It's genuinely free — every Roof Treatment includes a full gutter clean at no extra charge, always. It's never billed separately.

Colorbond and metal roofs, concrete tile, and terracotta tile — terracotta is more fragile so it gets specialist, low-pressure care.

Roof treatments are a flat $750 for single storey homes with 3 bedrooms or fewer, $840 for larger single storey homes, and $960 for double storey — the same price no matter your roof type or moss severity, and every quote includes a free gutter clean. Every quote is free to obtain.

Per visit, it can look similar or even cheaper — but pressure washing doesn't kill moss at the root, so it typically needs redoing every 12–18 months. Over the 3–5 years one Roof Treatment protects for, that's usually 2–3 repeat pressure washes, which can add up to $1,500–$2,250 — compared to a single flat price starting at $750 for the treatment. That's often $1,000 or more back in your pocket for the same stretch of time, without the risk of cracked tiles along the way.
