Safe soft-wash roof cleaning across Melbourne for tile and metal roofs — lifting moss, lichen and grime without the damage high pressure can cause.
8 min read FreshDuct Melbourne Melbourne, Victoria
A clean roof protects your home, looks far better, and lasts longer. Over the years, Melbourne roofs collect dirt, grime, moss, lichen and algae — and left unattended, that growth holds moisture against the surface and works into joints and coatings, accelerating wear. FreshDuct cleans tile and metal roofs across Melbourne using soft washing — a low-pressure method that lifts growth and grime without the damage high pressure can cause. Every job starts with an inspection.

High-pressure blasting can crack tiles, strip protective coating and force water under the roof; soft washing uses low pressure and appropriate treatment to lift dirt, moss and lichen without that damage. The method is matched to the roof.
Why Clean Your Roof
A roof is one of the largest, most exposed and most valuable parts of a property, and it benefits from proper care. Beyond the obvious improvement in appearance — a clean roof transforms how a house looks — cleaning protects the roof itself. Moss and lichen hold moisture against the surface and work into gaps and coatings; grime and algae weather the finish. Removing them and keeping the roof clean slows deterioration and helps the roof last. A neglected roof not only looks tired, it ages faster.
The Right Method Matters
How a roof is cleaned matters as much as cleaning it at all. High-pressure blasting might seem effective, but on many roofs it does real harm — cracking and chipping tiles, stripping the protective coating, and forcing water up under the tiles where it shouldn’t go. That is why we favour soft washing: a low-pressure method that uses an appropriate treatment to lift dirt, moss and lichen, then a gentle rinse, leaving the roof clean and intact. The right approach depends on the roof, which is why we inspect first. See our soft washing guide.
Tile and Metal Roofs
We clean both tile roofs — concrete and terracotta — and metal/Colorbond roofs, with the method suited to each. Tile roofs collect moss and lichen readily, especially under tree cover, and need a method that won’t crack the tiles or strip their coating. Metal and Colorbond roofs need a method that protects the factory coating that guards the steel from rust. In both cases, soft washing cleans effectively without the damage harsh methods cause. See our tile and metal/Colorbond guides.
What Roof Cleaning Removes
Roof cleaning removes the build-up that accumulates over years: dirt and grime, moss, lichen, algae and general weathering. Moss and lichen are the most damaging — they retain moisture and intrude into the surface — so removing them does more than improve looks. After a soft-wash treatment, treated growth frequently keeps washing away with subsequent rain, so the roof continues to improve. The result is a roof that is clean, protected and looking close to its best. See our moss & lichen guide.
How Often to Clean
The right interval depends on your property. Roofs shaded by trees, or in damp, south-facing or low-airflow positions, grow moss and lichen faster and need cleaning more often; exposed, sunny roofs stay cleaner longer. As a general guide, many roofs benefit from cleaning every few years or whenever growth and grime become noticeable. After inspecting your roof we can suggest a sensible interval to keep it clean and protected without over-servicing.
Getting a Quote
Roof cleaning is quoted per job after an inspection — roof type, size, pitch, access and the amount of growth all affect the work. We inspect the roof, recommend the right method and work, and provide a clear quote. Call 0431 918 137 or request a quote and inspection. See our cost & quoting guide.
Frequently Asked Questions
How much does roof cleaning cost in Melbourne?
Roof cleaning is quoted per job after an inspection, because the cost depends on the roof type, size, pitch, access and how much growth and grime there is — a single-storey tile roof and a steep, two-storey roof heavy with moss are very different jobs. Rather than a misleading list price, we inspect the roof, recommend the right work, and provide a clear quote. Like any trade, a minimum call-out applies. Call 0431 918 137 or request a quote and inspection.
Is it safe to pressure wash a roof?
High-pressure blasting can damage a roof — it can crack or chip tiles, strip the protective coating, and force water up under the tiles — which is why we favour soft washing for roofs. Soft washing uses low pressure and an appropriate treatment to lift dirt, moss and lichen without that damage. The right method depends on the roof type and condition, which we assess on inspection. See our soft washing guide.
What does roof cleaning actually remove?
Roof cleaning removes the dirt, grime, moss, lichen, algae and general weathering build-up that accumulates on a roof over the years. Moss and lichen in particular are not just unsightly — they hold moisture against the surface and work into joints and coatings, so removing them protects the roof as well as improving its appearance. After a soft-wash treatment, treated moss and lichen often continue to wash away with rain over the following weeks. See our moss & lichen guide.
Does roof cleaning damage the tiles or coating?
Not when it is done correctly. The risk of damage comes from using high pressure on a roof that can’t take it — that is what cracks tiles and strips coatings. Soft washing avoids this by using low pressure and the right treatment, so the roof is cleaned without harm. On older or fragile roofs especially, method is everything, which is why we inspect first and match the approach to the roof. A correctly cleaned roof is left intact and protected.
How often should a roof be cleaned in Melbourne?
It depends on the property — tree cover, roof type, orientation and dampness all affect how quickly moss, lichen and grime build up. Roofs shaded by trees or in damp, south-facing positions grow moss faster and need cleaning more often. As a general guide, many roofs benefit from cleaning every few years, or whenever growth and grime become noticeable. We can advise an appropriate interval after inspecting your roof. See our cost & quoting guide.
