Black streaks gone. Roof looking sharp again.

No — soft washing is the method most tile and Colorbond manufacturers recommend. It's high-pressure water blasting that typically voids warranties, because it strips protective coatings and can crack tiles or damage paint finishes. We use low-pressure application specifically to stay warranty-safe.

Most jobs cost between $4 and $8 per square metre, so a typical 200m² single-storey roof runs $800 to $1,400. Price depends on pitch, access, tile type and how heavy the moss, lichen or algae growth is. We provide a fixed quote after assessing photos or inspecting on-site.

Yes. We use a gentler soft wash formulation for Colorbond and other steel roofs — no abrasive brushing and no harsh acidic chemicals that strip the factory paint system. It removes algae staining and dirt without affecting the coating or your BlueScope warranty.

We remove moss, lichen and black streak algae from the root, not just the visible growth on top. Pressure washing knocks growth off the surface but leaves roots intact, so it grows back fast. Our treatment kills the organism and slows regrowth.

Yes. We use biodegradable cleaning solutions and tarp off gardens and outdoor areas below the work zone. We also flush gutters and downpipes after cleaning so residue doesn't sit and cause corrosion or affect rainwater tanks.

Every 2 to 3 years is typical for most Brisbane homes, though shaded, tree-lined properties with heavy moss or lichen growth may need it more often. Regular cleaning stops growth from taking hold and getting into the tile surface, which is cheaper than remediating a badly affected roof later.

Yes. Our crews are harnessed and trained in height safety for steep pitches, two-storey homes and heritage roofs, and we are fully insured for public liability. We use proper anchor points rather than standing on ridge capping or leaning ladders on gutters.
