Professional roof and gutter cleaning across the Central Coast. Remove moss, lichen, debris and leaf build-up to extend roof life and prevent water damage.
The Central Coast's humid coastal climate creates ideal conditions for moss, lichen, algae and mould growth on roof tiles. Left untreated, biological growth traps moisture against the tile surface, accelerating deterioration. Porous concrete tiles absorb water, leading to cracking in winter and efflorescence (white salt deposits) that weakens the tile structure over time.
Regular roof cleaning — typically every 2–5 years depending on your property's exposure — removes biological growth before it causes permanent damage, restores the tile's water-shedding properties, and extends the roof's serviceable life by 10–15 years compared to an unmaintained roof.
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. We never use ladders propped against gutters.
Blocked gutters are the number one cause of roof leaks on the Central Coast. Leaf litter, seed pods, and silt accumulate in gutters and downpipes, causing water to overflow into the fascia, soffit and wall cavity. In heavy rain, a single blocked downpipe can direct hundreds of litres into your ceiling space.
Our gutter cleaning service includes:
The recommended frequency depends on your property's surroundings:
| Property Type | Roof Cleaning | Gutter Cleaning |
|---|---|---|
| Under heavy tree canopy (eucalyptus, pine) | Every 2–3 years | Every 6 months |
| Moderate tree coverage | Every 3–4 years | Annually |
| Open/minimal trees | Every 4–5 years | Every 18 months |
| Coastal (salt exposure) | Every 2–3 years | Annually |
Properties surrounded by eucalyptus trees on the Central Coast typically need gutter cleaning twice per year — once after the autumn leaf drop and once after the spring seed/bark shed.
Pricing depends on roof size, pitch, access difficulty, and the extent of biological growth. The table below shows typical ranges:
| Service | Typical Cost Range | What's Included |
|---|---|---|
| Roof clean — standard home (150–250m²) | $800 – $1,800 | Soft-wash treatment, low-pressure rinse, valley clean |
| Roof clean — large home (250–400m²) | $1,800 – $3,000 | As above, larger area |
| Gutter clean — single storey | $250 – $450 | Debris removal, downpipe flush, condition report |
| Gutter clean — double storey | $400 – $650 | As above, scaffold/harness access |
| Roof + gutter clean combo | $1,000 – $2,200 | Full roof clean plus gutter service |

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 (under 2,000 PSI). This removes growth without stripping tile coatings or causing surface damage.
A standard residential roof clean takes 4–6 hours depending on size and the extent of growth. We complete most jobs in a single day.
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.
The biocides we use are biodegradable and break down within 24–48 hours. We divert downpipes away from rainwater tanks during treatment and flush gutters before reconnecting.
Yes. We supply and install aluminium mesh gutter guards that prevent leaf and debris entry while allowing water flow. Guards significantly reduce the frequency of gutter cleaning required.
