What we solve
If any of this sounds familiar, you're in the right place.
Dark green and black streaks
Gloeocapsa algae and lichen feeding on tile minerals. Our treatment kills them at the spore so they don't grow back next season.
Moss lifting tiles and capping
Moss roots between tiles and pries them apart, letting water in. We treat it cleanly without breaking tiles or dislodging ridge capping.
Selling and the roof looks tired
A roof treatment is the highest-impact street-view upgrade dollar-for-dollar before listing your home.
Insurance, strata or warranty request
We provide before-and-after photos and an invoice suitable for insurance claims, strata compliance and manufacturer warranty records.
Why treatment, not pressure-blasting
High-pressure blasting cracks tiles, lifts ridge capping and strips seals and coatings. Our soft-wash treatment applies a biodegradable biocide at low pressure, kills biological growth at the spore and lets rain finish the rinse over the following weeks. The result is deeper, longer-lasting and warranty-safe.
The chemistry we use
Our treatment is a professional-grade sodium hypochlorite blend with a low-foaming surfactant, mixed on site to the correct concentration for your roof type. It breaks down into salt and water within days and is safe around plants when applied by a trained technician.
Safe roof access
Our technicians are roof-safety trained and equipped for steep-pitch and complex tile work with harnesses and anchor systems. If a roof isn't safe to access, we tell you upfront. Safety always wins.
Bundle and save
Most customers add gutter cleaning at the same time and save on the call-out. We can also coordinate solar panel cleaning so panel run-off doesn't undo the roof treatment.

FAQ
Common questions.
What is a roof treatment?+
A roof treatment is a low-pressure soft-wash application of a biodegradable biocide that kills moss, lichen and algae at the spore. Unlike high-pressure blasting, it protects tiles, paint and seals and the results last for years as rain gently rinses the residue away.
How is a roof treatment different to a roof clean?+
A roof clean removes what you can see today. A roof treatment kills the biological growth at the root so it does not return next season. We include the treatment as standard on every roof job.
Will the treatment damage my tiles or Colorbond?+
No. We never high-pressure roofs. The soft-wash chemistry is safe for terracotta, cement, slate and Colorbond and is compatible with paint warranties.
How long does a roof treatment last?+
Most Melbourne roofs stay clear of moss and lichen for 3 to 5 years after treatment. South-facing or heavily tree-shaded roofs may benefit from a top-up sooner.
How soon does the roof look clean?+
You will see an immediate lift on the day. The deep-clean effect continues over 4 to 8 weeks as rain rinses the dead growth away for a clean, even finish.
Can I bundle a roof treatment with gutter cleaning?+
Yes, and we recommend it. One visit, one setup, one tidy. Most homes save on the call-out by bundling the treatment with gutters or a full house wash.
