Your roof protects the most valuable thing you own, so it deserves more than a quick blast. Concrete and terracotta tiles get a controlled pressure clean, Colorbond gets a low-pressure soft wash so the paint is never stripped, and every roof clean finishes with the gutters cleared and the overspray washed off your walls and windows. Roof cleans start from $1,000 for an average single-storey home.
Black streaks running down the roof, or tiles that look darker on the shaded side
Grey-white crusty spots (lichen) that will not rinse off with a hose
Moss in the tile joints or along the ridge
Gutters that keep filling with grit and green sludge
You are selling, or a building and pest report flagged the roof
Why do Gold Coast roofs go black so quickly?
Rain and humidity. The Bureau of Meteorology's Coolangatta station averages roughly 1,500 mm of rain a year, with February and March the wettest months, and afternoon humidity sits in the 60s for most of the year. Concrete tiles soak that up and stay damp, which is exactly what black mould, green algae and grey-white lichen need.
Beachfront streets from Kirra to Main Beach add salt spray, and canal-side homes in Broadbeach Waters, Mermaid Waters and Varsity Lakes rarely get a full dry-out on the shaded faces. That is why a roof in Palm Beach can look ten years older than the same roof inland.
Tile pressure clean or Colorbond soft wash: which does your roof need?
Concrete and terracotta tile roofs, common on 1970s to 1990s homes in Elanora, Burleigh Waters, Miami, Robina and Southport, take a controlled pressure clean with a wide fan or rotary surface cleaner. The pressure is eased right back on chalky or weathered tiles, and a good operator checks for cracked tiles and loose ridge capping as they go.
Colorbond, Zincalume and painted metal roofs should never be blasted. High pressure dulls and strips the coating. They get a soft wash instead: a mild cleaning solution, a dwell time, then a low-pressure rinse. Painted or coated tiles are treated the same way.
What happens on the day?
The operator sets up safety gear, covers or rinses gardens below the drip line, and blocks downpipes if needed so debris does not wash into tanks or the stormwater. The roof is treated or cleaned from the top down, then the gutters are cleared, because everything that comes off the roof ends up in them. A standard single-storey roof is usually a one-day job.
Is it an asbestos (fibro) roof? Then it must not be pressure cleaned
Some older beach houses, garages and sheds still have corrugated asbestos cement roofing. Using high-pressure water on asbestos cement is against the law in Queensland because it spreads fibres across the property and the neighbours' yards. If your roof might be fibro, say so on the quote form. It will not be pressure cleaned, and you will be pointed to a licensed asbestos assessor.
How much does roof cleaning cost on the Gold Coast?
Job
Our price
Tile roof pressure clean
from $1,000
Colorbond / metal roof soft wash
from $1,000
Gutters cleared after the roof clean
Included
Starting price for an average single-storey home. Roof area, pitch, a second storey and how heavy the lichen is move the price, and it is confirmed before any work starts. We sit a little above the cheapest on the Gold Coast. Here is what the difference pays for, and how it compares in the Gold Coast pressure cleaning cost guide.
Included at every price
Soft wash on roofs: low pressure and a cleaning solution, so tiles and paint aren't blasted
Gardens, windows, cars and pool protected before the clean starts
Overspray rinsed off walls, windows, fences and paths before we leave
Gutters cleared and flushed after every roof clean
Before and after photos sent to you when the job is done
A roof condition report: if anything on the roof is a concern or needs repairing, you get a written report of what needs doing, with photos
A walk-around with you before payment
Before and after photos, plus a roof report
You get before and after photos of every job. On roof cleans, anything that is a concern or needs repairing (cracked tiles, loose ridge capping, rust, leak points) goes into a written report of what needs to be done.
$20M public liability, certificate on request
Our standard
Your home is worth more than a quick blast
Your home is probably the biggest thing you own. A rushed, cheap clean can strip paint, crack tiles, flood the gutters and leave grime splashed up your walls and windows. That's why every job we pass on is done to the same standard, by an insured local operator who agrees to it before they get the work.
The right method for the surface
Soft wash for paint, render and Colorbond. Controlled pressure for tile and concrete. Never blasting a surface that can't take it.
Your property protected first
Gardens rinsed, windows, cars, furniture and pool covered or moved, downpipes blocked so grit doesn't end up in tanks or drains.
Overspray washed down
Splashback is rinsed off walls, windows, fences and paths before packing up, so the clean doesn't leave a new mess somewhere else.
Roof know-how, not just a hose
Roof cleans go to operators with roofing industry experience. While they're up there they check for cracked or slipped tiles, loose ridge capping, rust and leak points, and send you photos of anything that needs fixing.
Gutters cleared after every roof
Everything that comes off a roof lands in the gutters, so they are cleared and flushed as part of every roof clean.
Left cleaner than we found it
Debris bagged and taken away, paths and driveways rinsed, nothing left behind.
A walk-around before payment
Before and after photos, and a walk around the job with you. The price is confirmed before work starts and doesn't change without your say-so.

Roof Cleaning questions
Yes. Roof cleans go to operators with roofing industry experience, and a roof check is part of every clean. Cracked or slipped tiles, loose ridge capping, rusted sheets and likely leak points are photographed and sent to you with the after photos, so you know exactly what needs fixing and how urgent it is.
Every two to four years for most homes. Roofs under trees, on the shaded side of a hill or close to the beach usually need it sooner. If nothing is growing and it is only dusty, leave it.
Done properly, no. The risk comes from too much pressure on old, chalky tiles or any pressure at all on Colorbond. That is why the method is matched to the roof: controlled pressure for sound concrete or terracotta tiles, soft wash for metal and coated surfaces.
Usually not, as long as there is an outdoor tap, side access and pets are inside. The operator will confirm on the phone.
No. A clean removes growth and dirt. A restoration also repairs, rebeds, repoints and recoats the roof. This service covers cleaning only.
After the wet, from about April onwards, when growth is at its worst and the heavy rain has passed. Before listing a property for sale is the other common time.
