This guide provides real pricing based on our experience cleaning roofs across Sydney. We break down the costs by roof size and type so you know what to expect before requesting a quote.
Roof Cleaning Costs by Roof Size
Here are typical price ranges for professional roof cleaning in Sydney:
| Roof size | Typical cost |

| Small (up to 120 sqm) | $350 to $600 |
| Medium (120 to 200 sqm) | $600 to $1,000 |
| Large (200 to 300 sqm) | $1,000 to $1,500 |

Cost by Cleaning Method
The two main methods for roof cleaning are high-pressure cleaning and soft washing. The method affects the cost:
| Method | Typical cost | Best for |
|---|---|---|
| High-pressure cleaning | $400 to $1,200 | Concrete tiles with heavy moss or dirt buildup |
| Soft washing | $500 to $1,500 | Terracotta tiles, Colorbond, older or fragile roofs |
Soft washing costs slightly more because it uses specialised cleaning solutions and takes longer to achieve results. However, it is the only safe option for terracotta tiles, aged concrete tiles, and metal roofs where high pressure could cause damage.
We always inspect your roof before recommending a method. Using the wrong technique can crack tiles, strip protective coatings, or force water under the roofing material into your ceiling.
Additional Service Costs
Most homeowners combine roof cleaning with one or more additional services:
| Additional service | Typical cost |
|---|---|
| Anti-fungal and anti-moss treatment | $150 to $400 |
| Gutter cleaning (included by some companies) | $150 to $350 |
| Minor tile replacements (found during cleaning) | $200 to $500 |
| Ridge capping repointing (if deteriorated) | $800 to $2,500 |
Anti-fungal treatment
An anti-fungal coating applied after cleaning slows regrowth for 12 to 18 months. It adds to the upfront cost but means your roof stays clean longer, which can actually save money over time by extending the gap between professional cleans. We recommend it for roofs that are shaded by trees or have south-facing sections where growth returns quickly.
Gutter cleaning
Some companies include gutter cleaning in the roof cleaning price. Others charge it separately. Roof cleaning inevitably washes debris into your gutters, so they need to be cleared afterwards regardless. Ask whether gutter cleaning is included in your quote.
What Affects the Price?
Roof size and complexity
Larger roofs take longer to clean and require more water and cleaning solution. Complex roof designs with multiple ridges, valleys, and hip lines also take longer than simple gable roofs because each junction requires careful attention.
Roof pitch
Steeper roofs require additional safety equipment and take longer to work on safely. A low-pitch roof (under 25 degrees) is the easiest and most affordable to clean. Steep pitches (over 35 degrees) add to the cost.
Level of growth
A roof with light surface dirt cleans faster than one with thick, established moss and lichen. If your roof has not been cleaned in 10 years and has heavy biological growth, expect to pay toward the higher end of the price range. Regular cleaning every 2 to 3 years keeps costs lower each time. See our guide on how often to clean your roof for recommended schedules.
Access and height
Single-storey homes with easy access are the most affordable to clean. Two-storey homes, steep blocks, and properties where equipment cannot be brought close to the building all add to the cost.
Roof material
Concrete tiles can handle high-pressure cleaning, which is faster and therefore less expensive. Terracotta tiles and Colorbond roofs require soft washing, which takes longer and costs slightly more.
DIY vs Professional: Is It Worth Doing Yourself?
A consumer-grade pressure washer costs $200 to $800 to buy or $80 to $150 to hire for a day. On paper, cleaning your own roof seems like a significant saving. In practice, it is not worth the risk.
| Factor | DIY | Professional |
|---|---|---|
| Cost | $80 to $200 (hire plus materials) | $500 to $1,200 |
| Safety | High risk (falls from roofs cause serious injuries) | Trained with safety harnesses and equipment |
| Result | Moderate (consumer equipment lacks power) | Thorough (commercial equipment and experience) |
| Tile damage risk | High (wrong pressure or angle cracks tiles) | Low (experienced operators know the right technique) |
| Time | 4 to 8 hours | 2 to 4 hours |
| Insurance | Your home insurance may not cover DIY roof work injuries | Professionally insured |
The biggest risk is safety. Falls from roofs and ladders account for a significant proportion of serious home injuries in Australia. Wet, mossy tiles are extremely slippery, and a consumer pressure washer makes the surface even more dangerous while you are standing on it.
The second risk is damage. Using too much pressure on terracotta tiles cracks them. Holding the nozzle too close to concrete tiles strips the coating. Directing the spray uphill forces water under tiles and into your ceiling. Professional roofers know how to avoid all of these problems.
How Often Should You Pay for Cleaning?
For most Sydney homes:
| Situation | Recommended frequency | Approximate annual cost |
|---|---|---|
| Minimal shade, north-facing | Every 3 years | $200 to $400 per year |
| Moderate shade or south-facing sections | Every 2 years | $300 to $600 per year |
| Heavy shade, near bushland | Annually | $500 to $1,200 per year |
Spreading the cost out annually shows that professional roof cleaning is a modest expense, especially when you consider that it prevents moss and lichen damage that leads to far more expensive roof repairs down the track.
Getting the Best Value
- Combine services. Getting your roof cleaned, gutters cleared, and an inspection done at the same time is more cost-effective than booking them separately. We offer this as a combined service.
- Clean regularly. A roof cleaned every 2 to 3 years is faster and cheaper to clean each time compared to a roof left for 10 years.
- Add anti-fungal treatment. The upfront cost pays for itself by extending the time between cleans.
- Address repairs at the same time. If our roofers spot cracked tiles or deteriorated pointing during cleaning, fixing them on the spot avoids a separate call-out fee later.
