Roof Cleaning Sydney
Roof cleaning is the job we're best known for, and the one we'd most strongly discourage you from attempting yourself. Sydney roofs are steep, brittle underfoot and slick once wet, and the work sits squarely inside working-at-heights regulations.

Clean & Capture
Waste water recovery
We clean terracotta, cement tile, slate, Colorbond and metal roofs right across Sydney — removing lichen, moss, black mould and accumulated debris, then clearing the gutters and valleys so water actually goes where it's supposed to.
Why a dirty roof is more than a cosmetic problem
Lichen doesn't sit on top of a tile — it bonds into the surface and holds moisture against it. On cement tiles that accelerates the breakdown of the surface coating. In gutters and valleys, decomposing moss and leaf litter block drainage, and blocked valleys are one of the most common causes of internal water damage we see.
A clean roof also runs cooler and lets rainwater harvesting systems collect water that isn't full of organic debris.
How we clean a roof safely
Every roof gets an inspection first — we're looking for cracked tiles, failed pointing, rusted valleys, loose ridge capping and previous repair work. You get told what we find, in writing, with photos.
Growth is then treated so it dies off, cleaned at the pressure appropriate to the roof material, and the gutters, valleys and downpipes are flushed clear. Fall protection and harnessing is used as required, and we cover and protect solar panels, skylights, whirlybirds and evaporative units.
Cleaning is often step one of a restoration
Once a roof is clean, its real condition becomes obvious. Plenty of our clients clean first, then decide to repoint the ridge capping or repaint the tiles while the access equipment is already on site. We do all of it in-house, so nothing needs to be coordinated between trades.
What you get

- Gutters, valleys and downpipes flushed as part of the job
- Written condition report with photos of anything we find
- Harnessed, licensed and insured crews working at height
- Waste water captured, so no debris-laden slurry down the drains

Our process
How we approach roof cleaning
- 01
Site assessment & quote
We inspect the surface, identify what's actually causing the staining, then send a written fixed-price quote with inclusions spelled out. No vague hourly rates.
- 02
Set up & protection
Gardens, fittings, drains and adjoining surfaces are protected before a drop of water is used. Access, hoses and leads are run so the site stays safe and tidy.
- 03
Treat, then clean
Organic growth is chemically treated first so it dies at the root, then we clean at the correct pressure and temperature for the substrate.
- 04
Waste water capture
Our Clean & Capture system vacuums waste water to a holding tank as we work, so nothing contaminated enters the stormwater system.
- 05
Final walk-through
We walk the job with you (or send photo documentation for commercial and strata clients) and only pack up once you're satisfied.
Real results
Results you can see from the street
Treatment first, then correct pressure for the substrate. That's the whole trick — and it's why the result lasts.
Why choose us
Serious equipment, correct method, no guesswork
Exterior cleaning done badly damages render, strips coatings and cracks tiles. Here's how we avoid all three.
On the tools since 1998
Not a franchise and not a call centre. You deal with the same small crew that turns up and does the work.

Clean & Capture waste water
Waste water is vacuumed and recovered as we clean, so nothing contaminated enters the stormwater system. It also lets us clean indoors.
Right method for the surface
Soft washing for render, coatings and roofs. Correct-pressure cleaning for concrete and masonry. Steam where heat beats pressure.
Treatment, not just a rinse
Mould and lichen are killed at the root before anything is rinsed, which roughly doubles how long the result lasts.
Fixed written quotes
Scope and inclusions in writing before we start. No hourly creep, no surprises on the invoice.
FAQs
Roof Cleaning — common questions
Will high pressure cleaning damage my roof tiles?
Sound tiles handle correct-pressure cleaning fine. Old, spalling cement tiles and fragile terracotta get lower pressure and a longer chemical dwell time instead. We assess the roof before we choose a method — and we tell you if a roof genuinely shouldn't be pressure cleaned.
Do you clean the gutters as well?
Yes. Clearing gutters, valleys and downpipes is part of every roof clean — there's no point cleaning a roof and leaving the drainage blocked with the debris.
Can you clean around solar panels?
Yes. Panels, skylights, whirlybirds and vents are protected before we start, and we clean carefully around mounting rails where debris collects.
How often should a Sydney roof be cleaned?
Every 3–5 years for most homes. Properties under heavy tree canopy, on the North Shore or close to the coast often need it every 2–3 years.
Do I need my roof painted after cleaning?
Not necessarily. Cleaning alone restores most roofs. Painting makes sense when the surface coating on cement tiles has worn away — we'll tell you honestly which situation you're in.
