Over time, driveways, paths, walls and roofs collect dirt, mould, algae and stubborn stains that can leave your property looking tired and slippery. Aabacus Roofing Solutions provides professional high pressure cleaning across Sydney, using the right cleaning method and pressure for every surface to deliver a thorough clean without causing unnecessary damage.
As experienced roofers, we also clean areas that many pressure cleaning companies avoid, including tile roofs, gutters, and second-storey render. With the right equipment and experience working at heights, we can safely clean both hard-to-reach areas and ground-level surfaces.
Thrives on the shaded, southern faces of Sydney roofs and anywhere trees keep tiles damp. Moss holds water like a sponge against the tile through winter, accelerates surface erosion, and in heavy mats can wick moisture up under tile laps, the source of more than a few mystery damp patches.
The crusty grey-green discs. Lichen anchors into the tile surface with root-like structures; rip it off carelessly or blast it at driveway pressure and the tile’s sealed layer comes away with it. It has to be killed first so it releases, which is what our biocide treatment does.
Not alive, but the most damaging of the lot: dammed valleys and gutters are where most overflow leaks start. Every roof clean we do includes clearing and flushing them, a clean roof draining into blocked gutters is half a job.
The dark streaking on older cement tiles, worst on the weather side. Mostly cosmetic, but it reads as tired roof from the street, holds surface moisture, and always accompanies a coating that’s near the end of its life, a useful early signal that a roof restoration conversation is a few years away.
Your roof | Right method | Why |
Sound cement tiles (esp. pre-coating) | Controlled high pressure | Tile surface tolerates it; fastest full strip before restoration or painting |
Older cement tiles, worn surface | Soft wash | Porous tiles lose more surface under pressure; solutions do the work instead |
Glazed terracotta (any age) | Soft wash only | Pressure strips the fired glaze and turns a sound roof porous |
Heavily lichened roofs | Biocide first, then gentle wash | Lichen must die and release; tearing it off takes the tile surface with it |
Hard surfaces below the roofline, driveways, paths, walls, pool surrounds are a different discipline with different equipment, covered on our high pressure cleaning page.
We check the roof type, its age, and the condition of the existing coating. We explain the best cleaning method before any work begins.
A treatment is applied to remove moss and lichen at the source and help slow future regrowth.
We use soft washing or controlled pressure cleaning, depending on the roof. Delicate areas such as flashings and roof penetrations are cleaned carefully by hand.
Gutters and roof valleys are cleared and flushed as part of every roof cleaning service.
We provide photos of any issues we find, such as cracked tiles, worn pointing, rust, or damaged flashings, along with honest advice on what should be repaired.

Most standalone roof cleans fall between $[600–1,500] depending on roof size, pitch, growth level and access, with gutters included. Quotes are itemised and fixed before we start.
Not with the right method, that’s the entire reason we run both soft wash and controlled pressure setups. Glazed terracotta is never high-pressured, and worn cement tiles are soft washed. The damage stories come from one-machine operators.
The biocide treatment kills growth at the root and keeps roofs clear for 2–3 years; shaded, tree-covered roofs regrow sooner. Blast-only cleaning without treatment regrows within a season, which is why we don’t do it that way.
Roof cleaning is a tile-safe discipline, method matched to tile type, biocide treatment, gutters and inspection included. Pressure cleaning is the high-force service for hard surfaces like concrete and stone. We offer both, on the right surfaces.
Yes, with soft methods only, while we’re up there for the roof. Dirty panels cost you generation; cleaning them at roof-clean time is the efficient way to do it.
Always, gutters and valleys are cleared and flushed as part of every roof clean. A clean roof draining into blocked gutters still overflows into your eaves.
It’s the highest-return presentation spends, the roof dominates listing photos, and a moss-free roofline changes how the whole property reads. Pair it with a driveway clean and the difference is dramatic.
