Roof Cleaning
Moss, lichen and black streaks gone — without damaging a single tile.
About this service
Sydney roofs cop it all — moss and lichen in the shade, black algae streaks on the weather side, and a slow build-up of grime that makes even a sound roof look tired. Our roof cleaning removes all of it and treats the growth at the root so it doesn't bounce straight back.
We match the method to the roof: low-pressure soft washing for tiles and coated surfaces, and the right chemistry for the growth we find. No blasting, no cracked tiles, no water forced under the ridge capping.
The difference from the street is immediate — most customers say it looks like a new roof for a fraction of the cost of one.
- Free, fixed-price quotes — no surprises

FAQ
Roof Cleaning — your questions answered
Will cleaning damage my roof tiles?
No. We use low-pressure soft washing on tiled roofs, which kills moss, lichen and algae at the root without the blasting force that cracks tiles or strips surface coatings.
How long does a roof stay clean afterwards?
A soft-washed roof typically stays clean for years, because the treatment kills growth at the source rather than just rinsing the surface. Shaded, tree-covered roofs regrow sooner than open sunny ones.
How often should my roof be cleaned?
Every 12–24 months for most Sydney roofs — sooner under heavy tree cover or near the coast, where moss, lichen and salt build up faster.
Do you work safely at heights?
Yes — our whole team is trained and insured for working at heights, with proper harness and access equipment on every roof job.
Are you fully insured?
Yes — TGG SYD is fully insured, and we're owner-operated, so the person who quotes your job is the person responsible for the result.
Is the quote really free and fixed?
Yes. Quotes are free and fixed — you'll know the price before we start, with no hourly meter and no surprises on the invoice. A quick call with a couple of photos is usually all we need.
Pressure washing or soft washing — which will you use?
Whichever the surface needs. Hard surfaces like concrete driveways take high pressure; render, roofs, timber and painted surfaces get a low-pressure soft wash. We are trained in both and always match the method to the material.
