How Much Does Roof Cleaning Cost? Breakdown of Prices

Roofs are one of the most essential elements of a building, yet these are most often overlooked. A clean roof can improve the curb appeal of the building, making it stand out from the rest. Additionally, it helps prevent damage and extends the lifespan of the structure. If you are also thinking of opting for roof cleaning services but are concerned about the expense, you are in the right place.

Breakdown of Roof Cleaning Costs

Cleaning companies evaluate the scope of work and provide a price estimate, either on an hourly or per-square-metre basis. Since every roof is different, determining a flat fee for roof cleaning in Melbourne isn’t practical. Yet, most roof cleaning estimates range depends on the factor below:

Roof Material

The variations in roofing materials can significantly impact the cost of roof cleaning since each material needs to be targeted in a specialised manner to avoid harm. The most common Australian roofs are made of:

Metal: Tin, aluminium, steel, copper, and zinc all fall under the category of metal roofs. These are extremely long-lasting. However, coastal winds tend to accumulate salt on the surface that eventually corrodes these. Similarly, moss and mildew can also cause significant damage over time.
Terracotta: These high-end roofing materials require careful consideration during the cleaning procedures; otherwise, their lustre and durability can be damaged. Since it will take additional cleaning time, the costs can be higher than that of metal.
Concrete: Being a porous material, it allows mould, mildew, and algae to embed deeply, making the surface difficult to clean. Soft wash, along with a combination of moss treatments, is required to get rid of these effectively, which may contribute to increasing the final roof cleaning costs.
Tiles: Resistance to algae and moss makes tiles an easy-to-maintain roofing material that doesn’t require frequent and specialised cleaning methods, making them economical to clean.
Shingles: The light weight of shingles ensures accessibility. However, the textural surface traps dust, mould, and mildew, which makes cleaning time-consuming, adding up to the costs.
Plastic: The lightweight and non-porous surface ensures minimal grime buildup. Therefore, it demands less effort, materials, and costs.

Roof Type

The elevation can also cause substantial changes in the roof cleaning costs. Depending on whether the roof is steep, difficult to reach, or prone to grime accumulation, the roof cleaning prices can vary. The most common roofs in Australian buildings are:

Pitched Roofs: The sloping surfaces demand increased labour and time, thereby adding to the costs.
Flat Roofs: The most east-to-reach roofs can lead to costly cleaning only if there is standing water on the surface, causing algae and mould buildup.
Gabled Roofs: The two sloping sides meeting at a ridge make the roof moderately challenging to clean. The slightly more labour, time, and material requirements yield to medium rates.
Hip Roofs: Slopes on all sides make the structure complex, requiring additional resources for a thorough cleaning. Higher costs are involved due to the need for more labour and time.
Shed Roofs: Smaller structures or modern homes often have a single sloping surface known as shed roofs. The simplicity of design offers ease of accessibility, aiding in lower costs.
Dormer Roofs: The additional protrusions with windows add to the roof cleaning technicalities. Due to the need for extra time and effort, these require medium to highly priced roof cleaning, depending on the size.
Curved or Dome Roofs: The strikingly attractive but unconventional design creates immense challenges for cleaning professionals. These require additional customisation during the procedure, which makes them fall under the category of costly roof-washing services.

Roof Size

This one is simple. The size of your roof is directly proportional to the roof cleaning costs. The larger ones require additional time and resources, which contribute to higher prices.

Condition of the Roof

Unattended rooftops tend to accumulate much debris. These include leaves, twigs, dirt and other environmental elements. Similarly, algae and mould also find enough time to settle on the surface, making it look unappealing. If the rooftop is filled with grime, specialised cleaning agents and tools will be required. Additionally, there could be long cleaning hours that may add up to the standard cost. However, if you opt for periodic maintenance, you can save more in the long term since not much time or effort will be required to clean the roof deeply.

Building Type (Residential or Commercial)

Commercial roof cleaning often involves larger areas and more complex cleaning requirements as compared to residential roofs. The increased scale and potential need for permits or specialised techniques can increase costs.

Location of the Roof

Accessibility plays a critical role in pricing. Hard-to-reach roofs or properties in remote locations may incur higher charges due to additional time, equipment, or travel expenses.

Cleaning Methods

Soft wash: A gentle method suitable for delicate materials, ideal for removing algae and mildew. It is generally more expensive due to the use of biodegradable solutions. Also, only professionals can use these efficiently. If your roof requires soft wash cleaning, the roof cleaning prices may fluctuate.
High-pressure cleaning: Effective for tough stains but not recommended for fragile materials. Less chemical usage and quicker results make it a less expensive roof cleaning method. When performing cleaning through high-pressure wash, the cost of roof cleaning can vary.
Eco-friendly cleaning: Uses biodegradable solutions, appealing to environmentally conscious homeowners. Each method has its price point, with soft wash and eco-friendly options often costing slightly more due to specialised solutions and techniques.

Additional Services

Roof cleaning costs can increase with the inclusion of services such as:

Gutter cleaning: Adding gutter cleaning ensures your roof’s longevity. Get to know how much gutter cleaning can cost.
Moss and algae removal: The presence of moss and algae will require specialised techniques, such as the use of air washing and biocide, that can increase the cost of roof cleaning. Else, you can go with mould removal services in Melbourne.
Roof sealing: Long-term protection can be availed of with roof sealing. It delays moss and algae growth and also prevents water seepage, thereby safeguarding the construction.
Roof cavity cleaning: Amalgamating roof cavity cleaning will ensure that the space between the ceiling and roof is also looked into. It reduces impurities and prevents health hazards. When opting for roof cavity cleaning, the expenditure is estimated to rise.

Ideal Interval for Roof Cleaning Services

Regular roof cleaning every 1-2 years is advisable to maintain your property’s integrity. Homes in areas with heavy rainfall or tree cover may need more frequent cleanings to prevent debris buildup and moss growth. Scheduling routine cleanings reduces the need for extensive, costly maintenance later.

Signs You Must Opt for Roof Cleaning Services

Though there is an ideal interval for roof cleaning, it may change due to environmental factors. Therefore, it’s essential to keep a keen eye and opt for roof cleaning services when you see:

Visible moss, algae, or lichen growth
Water pooling or drainage issues
Accumulated debris, such as leaves or branches
Faded or discoloured roofing material.
Noticeable damage, such as cracked tiles or loose shingles

Acting promptly on these signs helps maintain a healthy roof and avoids escalating repair costs.
