A moss-covered, streaked roof isn’t just an eyesore. Moss, lichen and black algae trap moisture against your tiles and slowly eat into them. Action Roofing’s licensed roofers clean tile, terracotta, concrete and Colorbond roofs across Sydney safely, with soft wash or pressure cleaning matched to your roof, and finish every job with a biocide treatment that slows regrowth.
Sydney’s humidity, regular rain and shaded gardens make roofs a perfect home for moss, lichen and black algae. Left alone, that growth holds water against your tiles, lifts the surface coating, blocks valleys and gutters, and turns a roof you paid good money for into the worst-looking one on the street. A professional roof cleaning in Sydney reverses all of that, and done properly, it buys your roof years.
The difference with Action Roofing is who’s actually on your roof. We’re not a pressure-washing crew, we’re licensed roofers. While we clean, we check your ridge capping, flashings, valleys and broken tiles, so you find out about a small problem now instead of a leak later.
From terracotta and concrete tile to Colorbond and metal, across Western Sydney, the Hills District and the North Shore, we clean every roof type, and we’ll tell you honestly whether a clean is all you need or whether the roof would be better off restored.

Every roof cleaning service, step by step
Every roof material cleans differently, and the wrong method strips coatings and cracks tiles. Here’s how we treat each one. Every job is completed by licensed roofers, not subcontracted handymen.
Concrete and terracotta tiles are the most common roofs across Western Sydney and the Hills. We assess the coating first, then clean at the right pressure, or soft wash, to lift moss and lichen without blowing the colour off your tiles.
Older terracotta can “fret” and become fragile and unsafe to walk. Our terracotta roof tile cleaning is gentle, low-pressure and soft-wash based, treating algae and lichen and letting it wash clear, protecting fragile tiles.
Colorbond and metal need a specialist touch, as the wrong gear scratches the finish and starts rusting. Our metal and Colorbond roof cleaning uses a manufacturer-aligned low-pressure soft wash to clear grime and oxidation without damaging the coating.
Concrete tiles carry an oxide colour coating that black algae feeds on. We clean it back to its true colour and treat it, and tell you straight up if the coating is gone and the tile would be better resealed as part of a restoration.
A clean roof with blocked gutters still leaks. Our roof and gutter cleaning clears leaves and debris from gutters, valleys and downpipes in the same visit, and checks they’re draining, the most-searched combined job in Sydney for good reason.
For delicate, older or steep roofs, our soft wash applies a low-pressure biocide that kills moss, lichen and algae at the root, then washes clear with the rain. No high-pressure risk, and longer-lasting results than a quick rinse.
These are the signs Sydney homeowners book us for. If you can see any of them from the ground, it’s worth a quick inspection before the growth does real damage.
Moss and lichen hold moisture against the tile and slowly lift the surface. It's the most common reason shaded Hills District and Western Sydney roofs get booked in for a clean.
We soft wash or pressure clean to lift the growth, then apply a biocide that kills it at the root so it stays gone far longer than a simple rinse.
Send us a photo or book a drone inspection. We'll assess the roof, explain what it needs and give you a fixed price before any work starts.
NSW Licensed (Lic. 176125C) and fully insured. The person cleaning your roof can also repair it, and will tell you honestly if it needs it.
25+ years on Sydney roofs. We know which method suits terracotta versus concrete versus Colorbond, and we never guess with high pressure.
We inspect the whole roof before we touch it, so cracked tiles, failed pointing and blocked valleys get spotted and flagged, not just cleaned over.
You know the price upfront. No surprises and no upsell, backed by our workmanship guarantee and Dulux accreditation.
Send us a quick photo or book a drone inspection. We’ll assess your roof, recommend soft wash or pressure cleaning, and give you a fixed price-no obligation. It’s the roof cleaning Sydney homeowners book when they want honest advice and results that last, not just a quick rinse.
We keep every roof clean simple, transparent and respectful of your time and property.
We inspect your roof by drone, identify the growth and any problem spots, recommend soft wash or pressure cleaning, and give you a fixed-price quote. No obligation.
We cover the garden, protect surrounds, set up safe roof access and shield your and your neighbour's property, so there's no mess and no overspray left behind.
Soft wash or high-pressure clean as assessed, lifting moss, lichen and algae, followed by a steriliser and biocide treatment that kills regrowth at the root.
We clear gutters and downpipes, do a final inspection and flag any repairs, then leave your property spotless, with before and after photos for your records.
Most Sydney roof cleans start from a few hundred dollars and depend on roof size, pitch, roof type and how much moss, lichen or algae has built up. We give a fixed price after a drone inspection, so you know the exact cost before any work begins.
High-pressure cleaning blasts growth off immediately and suits sound concrete tile and metal roofs. Soft washing applies a low-pressure biocide that kills moss and lichen at the root and washes clear over the following weeks, which is safer for fragile terracotta, older and steep roofs. We assess your roof and recommend the right one.
On the wrong roof, yes. Too much pressure strips the colour coating off concrete tiles, cracks fragile terracotta and can force water into the roof cavity. That’s exactly why we assess first and soft wash where high pressure isn’t safe.
We remove all visible growth, then apply a biocide that kills it at the root to slow regrowth. No clean is permanent, but a treated clean lasts far longer than a roof that’s only been rinsed.
For most Sydney homes, every few years, and sooner for shaded, tree-lined or moisture-prone properties in the Hills District and the leafy North Shore where moss and lichen return faster.
Yes. We clean concrete tile, terracotta, Colorbond and metal, and match the method to the material. Older terracotta and Colorbond are soft washed, while sound concrete tile can take high pressure.
Yes. Our roof and gutter cleaning clears gutters, valleys and downpipes in the same visit and checks they’re draining properly, so a freshly cleaned roof doesn’t overflow during Sydney’s heavy summer rain.
Sometimes a clean is all you need; sometimes the coating is gone and you’d get far more value from a full restoration. Because we’re roofers, we’ll tell you honestly. See our professional tile roof restoration Sydney service for more.
