Sydney roofs face a constant battle with mould, lichen and algae, and the cause is usually the local conditions rather than the roof itself. SOAKD cleans roofs across the Sydney metro using a controlled, low-pressure softwash process that removes growth at the root while protecting your tiles and coatings. Every job is planned, documented under a SWMS and carried out by a height-access certified team with more than 20 years in high-risk construction.
Why Sydney roofs grow mould and lichen
Most roof growth in Sydney comes down to moisture and exposure. On the leafy, shaded North Shore and through the Hills District, tree cover keeps roofs damp for longer and drops spores and organic debris that mould and lichen feed on. Heritage homes with older, more porous tiles hold that moisture even more readily.
Coastal suburbs face a different pressure. Along the Northern Beaches and around Cronulla in the Sutherland Shire, salt-laden air settles on roof surfaces and accelerates the growth and deterioration of the materials. Left alone, lichen in particular sends roots into the surface of tiles, which is why a careful, root-level approach matters far more than simply rinsing the top layer away.
What softwash is and why it suits roofs
Softwash is a low-pressure method that relies on biodegradable cleaning solutions rather than force. The solutions kill mould, lichen and algae at the root, so the growth is treated properly instead of being stripped from the surface and left to return quickly.
This matters because roofs are not built to take high pressure. High-pressure cleaning can crack and chip tiles, strip protective coatings and drive water up under tiles and into the roof cavity. By keeping the pressure low and letting the solutions do the work, softwash protects the integrity of concrete tile, terracotta and metal roofs while still clearing the growth that has built up over the years.
Roof types we clean
We adjust our solutions and method to suit the material rather than treating every roof the same way. Across Sydney we regularly clean:
- Concrete tile roofs, common across much of suburban Sydney and prone to porous build-up of moss and lichen.
- Terracotta tile roofs, often found on heritage and older homes through the North Shore and Inner West.
- Colorbond and metal roofs, where algae and salt residue can take hold, particularly in coastal and exposed locations.
Roof Cleaning Prices in Sydney
Roof cleaning is quoted on the size, pitch, access and condition of your roof, so the figures below are a guide rather than a fixed price. Every job is confirmed after a free on-site assessment.
- Single-storey roof: typically around 500 to 1,200 dollars.
- Larger or two-storey roof: typically around 1,000 to 2,500 dollars or more.
- Free assessment and quote provided before any work begins.
Because access and the level of growth vary so much from home to home, an on-site look is the most reliable way to give you an accurate figure.
Areas we cover across Sydney
We work right across the Sydney metro, including the North Shore, the Northern Beaches, the Sutherland Shire, the Hills District and the Inner West. That takes in suburbs such as Hornsby, Chatswood, Manly and Cronulla, along with the surrounding areas. Whether your roof sits under heavy tree cover or close to the coast, we tailor the softwash to the conditions it faces.
To talk through your roof or arrange a free on-site assessment, call SOAKD on 0418 167 798 or request a free quote. We will walk you through the method and give you a clear figure before any work starts.
