Not all roofs require the same type of cleaning care. Here are the four main differences in figuring a roof cleaning cost average.

Roof material type

Metal and concrete are the most common roof material types in Australia. They are also the most economical to clean. There are also gravel roofs that require cleaning. The roof vacuum cost of this material can average $10 m2 and higher if the job is small. Terracotta is the most expensive material to clean and is found in high-end communities. Expect to pay more than the average.

Roof size and shape

The size and shape of your roof can make a difference in the price due to labour requirements. For example, roofs with a steep pitch require more equipment and time than a flat roof. 

An average estimate of roof cleaning cost based on size

Small roofs – $90 to $150

Medium roofs – $150 to $300

Large roofs – $300 to $550

Roof condition

If you have ignored your roof’s condition for several years, do not expect a roof cleaning company to be cheap. How much to pressure clean a roof can depend on the overall condition. The more time and cleaning it takes, the higher the price.

Whether you need extra services completed

When receiving a quote from a roof cleaning company, you may be made away of other areas that need repairing. The roof cleaning service can include a leaky roof, gutter cleaning and other types of repair.

Soft wash

A soft wash is a combination of low power washings and chemicals that remove the film and bacteria from the roof’s surface. The cost of this procedure will run from $250 to $600.

High pressure

High-pressure washing is exceptionally delicate, and only professionals should handle it. Built-up moss and algae can be difficult to remove without doing damage to a roof’s surface. Experienced roof cleaners know if pressure washing or a combination of chemicals and soft wash is needed. It can cost around $150 to $350 on average depending on your roof size.
