Roof & Exterior
Roof cleaning, without wrecking the roof
Soft-wash for tile and Colorbond across the Tweed and the Northern Rivers. We pick the pressure for the surface, not the other way around.
Northern Rivers tile roof half-cleaned, dark mould stripe meeting the original terracotta — illustrative placeholder until real photos are loadedMost roof-cleaning quotes you’ll get are one of two things: a high-pressure crew that strips the surface and drives water under the laps, or a soft-wash operator who treats and rinses properly. We’re the second one.
The mould you see on a Northern Rivers roof isn’t really dirt. It’s biological growth feeding on the surface, fed by humidity, leaf litter and shade. Pressure alone strips the visible top of it and leaves the roots; the dark stripes come back within a season. A roof-safe biocide breaks the growth down to the root, then a low-pressure rinse takes it away without abrading the tile or the Colorbond.
What we don’t do: walk a roof that isn’t safe to walk, blast tiles that are already cracking, or promise a roof clean will fix problems that are actually a roof restoration. If the pointing’s gone, if the ridge caps are loose, if the tiles are past their useful life, we’ll tell you on the quote and walk you through the options.
If the roof is sound but tired, a soft-wash will pull it back to something you’d happily put in a sale photo. We’ll send before-and-after pics either way.
When you need this
The reasons people call
- Dark mould stripes running down the tiles from the ridge
- Lichen patches growing on the north side, lifting with a fingernail
- Salt streaks on Colorbond after a season of easterlies
- Roof looks tired against the neighbour's, and you're getting the place valued
How we work
What actually happens
- Walk the roof, check the tiles, the pointing, the flashings and the gutters before we set up
- Treat with a roof-safe biocide, let it dwell, then soft-wash at a pressure that won't drive water under the laps
- Cocos-palm fronds and leaf litter pulled out of the gutters and downpipes as we go
- Rinse, sweep the surrounds, walk you around the roof when we're done
What's included
In the quoted price
- Pre-clean inspection of tiles, pointing, ridge caps and flashings
- Soft-wash treatment with roof-safe biocide
- Gutter clear-out and downpipe check
- Photos of anything we find that needs attention (cracked tile, lifted cap, rusted flashing)

A recent job
"Will pressure cleaning wreck my roof tiles?"
Banora Point, NSW · Roof clean, Banora Point hill house
The brief
Dark mould stripes running down the tiles from the ridge, cocos palms overhanging the roof, gutters overflowing in the last big rain. The owners wanted a quote for 'cleaning the roof'.
What we found
Loose ridge pointing on the eastern run, two cracked tiles near the valley, and a blocked downpipe at the rear corner where palm-frond seed clusters had built up over two seasons. Tiles themselves were structurally sound.
What we did
Treated with roof-safe biocide and dwelled fifteen minutes. Soft-washed at low pressure top-to-bottom. Cleared gutters and flushed downpipes. Photographed the loose pointing and cracked tiles, scoped them as a separate restoration line on the quote so the owner could decide whether to fix now or later.
Result
Roof looks fresh, gutters are flowing properly into summer storm season, the owner has photos of the pointing issue for their records. They booked the small restoration the following week.
FAQ
Roof Cleaning questions, answered
The mould came back last time we cleaned. Why?
Almost always because the last clean was pressure-only. High pressure knocks the visible mould off but doesn't kill the spores in the surface pores. Within a wet season the dark stripes are back. A roof-safe biocide breaks growth at the root, then a low-pressure rinse takes the dead material away. Done that way, the roof stays clean for two to three years instead of two to three months.
Our roof is too steep to walk on. Can it still be cleaned?
Most steep pitches we can soft-wash from the gutter line using an extension wand. Where the pitch is genuinely past walking and the wand can't reach, we'll set up a small platform or harness. The very rare roofs we won't touch are the ones where the access risk is real — and on those we'll tell you to leave it rather than push it.
We need a clean — but it might actually need a restoration. Which is it?
That's exactly the call the free roof / exterior check is for. Half the time a roof we're called to 'clean' is structurally fine and the clean is the right answer. The other half there's failing pointing, slipped tiles or a coating past its life — and a clean is money wasted on a roof that needs the restoration first. We diagnose before we quote.
