Professional roof and gutter cleaning across Northern Sydney. Remove moss, lichen, debris and leaf build-up to extend roof life and prevent water damage.
Northern Sydney's tree-heavy suburbs — particularly Wahroonga, Turramurra, Pymble, Gordon and Hornsby — create ideal conditions for moss, lichen and leaf accumulation on roofs. The dense eucalyptus and turpentine canopy traps moisture on tile surfaces, accelerating biological growth. Combined with the region's clay soils that retain moisture, roofs in Northern Sydney deteriorate faster than those in more exposed areas.
Regular roof cleaning — typically every 2–4 years depending on tree coverage — removes biological growth before it causes permanent damage, restores the tile's water-shedding properties, and extends the roof's serviceable life significantly.
We use a combination of soft-wash chemical treatment and controlled-pressure cleaning, tailored to your roof type:
All work is performed from scaffolding or roof anchors by licensed roofers with current Working at Heights certification.
Northern Sydney's heavy tree canopy means gutters block faster than almost anywhere else in Sydney. Eucalyptus bark, seed pods, and leaves accumulate rapidly — particularly in autumn and after storms. A single blocked downpipe can direct hundreds of litres into your ceiling space during heavy rain.
Our gutter cleaning service includes:
For properties under heavy canopy (common in Wahroonga, Turramurra, St Ives, Pymble), we recommend gutter cleaning every 6 months — once after autumn leaf drop and once after the spring bark shed.
Pricing depends on roof size, pitch, access difficulty, and the extent of biological growth:

We do not use high-pressure washing on roof tiles. Our soft-wash method uses a biocide to kill moss and lichen, followed by a controlled low-pressure rinse. This removes growth without stripping tile coatings or causing surface damage.
Properties under heavy eucalyptus canopy (common in Wahroonga, Turramurra, Pymble, Gordon) should have gutters cleaned every 6 months. Properties with moderate tree coverage can typically go 12 months between cleans.
Yes — we offer a combined roof and gutter clean at a discounted rate. Since we are already on the roof with safety equipment, it is the most efficient time to service gutters.
Yes. Slate roofs — common in heritage homes across Wahroonga and Turramurra — require gentle hand-cleaning and biocide treatment. We never pressure wash slate as it can cause delamination.
Yes. We supply and install aluminium mesh gutter guards that prevent leaf and debris entry while allowing water flow. Particularly recommended for properties under heavy canopy in Northern Sydney.
