Roof cleaning in Melbourne: expert exterior maintenance for longevity and curb appeal
The roof takes more weather than any other part of a building and gets looked at the least. Melbourne’s damp winters feed moss, lichen and mould, and that growth holds water against the surface, works into laps and fixings and shortens the life of the roof. Cleaning it is not about looks, it is what stops the slow damage.
We clean every common roof surface: tile, concrete, metal and Colorbond, glass, Perspex and fibreglass sheeting. The method depends on the material, because the wrong pressure can strip a coating and void the warranty, so a technician looks at the roof and its condition before deciding how to clean it.
Soft washing and pressure cleaning
Soft washing is the safest option for most roofs. It uses low pressure, around 150 to 300 PSI, with a biodegradable cleaner that breaks mould, mildew and algae down at the root rather than blasting it off. It suits older tile, shingle, slate and Colorbond, where a hard clean would do damage. Where a section is too steep or unsafe to reach, we can spray the treatment from the ground or an EWP and let it work over the following three to four months.
High-pressure cleaning, from about 1,300 to 2,800 PSI, is for heavy build-up on hard surfaces like concrete or terracotta tile, and as the prep step before a roof is repainted or restored. Even then we keep the pressure down, use a wide fan and stand well back, and we fix cracked tiles and ridge capping first so water cannot get in behind the clean.
Safety and the environment
Roof work is height work, so it runs to Australian WHS standards under WorkSafe Victoria. A risk assessment and SWMS are written with the crew before the job, everyone is trained and certified for height, and we work off harnesses, roof systems and secured ladders. We carry full Public Liability Insurance and every employee is covered by WorkCover.
Run-off is the other duty of care. We pre-wet and cover gardens and sensitive planting, and direct all run-off to approved drains rather than the stormwater system, in line with council and EPA guidance, using biodegradable products.
What it costs
A roof clean is quoted on the property, and as a rough guide it runs from about $500 for a small roof to $1,250 and up for a large one, quoted free after we have seen it. The main things that move the price:
- The roof size and material, measured in square metres and whether it is tile, concrete or Colorbond.
- The condition, since heavy moss, thick lichen or stubborn staining needs treatment, hand-scraping and dwell time.
- The access and pitch, because two storeys, a steep pitch or a fragile surface needs an EWP or rope access.
- The method, since soft washing with a chemical treatment can cost more than a straight pressure wash.
- How often it is done. An annual clean is cheaper than a one-off after years of build-up.
It is often worth doing the gutters in the same visit, since a clean roof needs the water to drain, and the solar panels too if you have them, because dirt cuts their output. Send us the roof type and the address, and we will quote the clean.
Frequently asked questions
Is high pressure cleaning safe for roofs?
High-pressure washing suits durable materials like sound concrete or terracotta tiles. Using high pressure incorrectly can gouge surface coatings, drive water under tile laps and shorten roof lifespan. Fragile surfaces like slate, shingles or Colorbond metal require soft washing with low pressure and chemical solutions to remove growth without damaging materials.
Why is roof cleaning important in Melbourne?
Melbourne's cold, wet climate accelerates the growth of moss, mould and lichen. These organisms trap moisture against roof materials, causing deterioration, tile cracking and metal corrosion. Heavy moss growth blocks water flow across tiles, forcing water into the roof cavity and leading to internal property leaks. Regular cleaning provides preventative maintenance against structural damage.
How often should a roof be cleaned in Melbourne?
Most roofs need professional cleaning every two to five years. Roofs shaded by trees, covered in leaf debris or positioned near busy roads with high traffic pollution require shorter maintenance cycles. Yearly inspections help identify early moss or algae growth, allowing treatment before thick layers cause tile damage or drain blockages.
Does roof cleaning damage gardens or surrounding plants?
Proper roof cleaning procedures protect garden beds and surrounding landscaping. Unmanaged wash runoff can harm plants and enter local waterways. Technicians cover delicate foliage, apply eco-friendly cleaning solutions and direct all wastewater into approved drains. These containment steps prevent chemical damage to soil, lawns and property gardens during the wash process.
Why hire height access specialists for low rise roof cleaning?
Low-rise roof work still involves significant height risks. Height access specialists bring commercial safety protocols to every residential job. Crews hold Working at Heights Certification and complete a Risk Assessment alongside a SWMS or JSA before climbing onto the roof. Fall prevention systems and controlled access techniques prevent fall injuries and avoid damage to roof tiles.

What affects the price of roof cleaning
Every building is quoted after we have seen it. These are the factors that move the number up or down - ask us about any of them and we will explain how they apply to your site.
| Height and access method | Rope access, elevated work platform or suspended platform - the method is chosen for the building, and it sets the crew size and setup time. |
| Surface area and condition | Heavy soiling, salt, traffic film or construction residue take longer and need specialised products. |
| Facade complexity | Recesses, angled or domed glazing, tight gaps between buildings and heritage detailing all slow the descent down. |
| Access and anchor points | Buildings with certified anchor points are quicker to set up. If there are none, temporary systems or installation are quoted separately. |
| Scheduling | Work outside trading hours, staged access or occupied tenancies affect the programme. Regular maintenance cycles are cheaper per visit than one-off jobs. |
Quotes are free and carry no obligation. Where the work is subject to a compliance requirement, the quote states which standard it is carried out to.
