Remove built-up dirt, moss, lichen and algae with a cleaning method chosen for the roof material, coating and condition.
Share a few details and we will explain the next step
The surface, access and drainage are assessed before the method is chosen
Roof cleaning can remove the dirt and biological growth that hide the surface and collect around drainage paths. The right approach depends on whether the roof is terracotta, concrete tile, Colorbond, another metal, slate or a flat roofing system.
We assess the pitch, access, coating condition and amount of growth before quoting. The scope can include pressure or soft washing, moss and lichen treatment, valleys, gutters, downpipes and cleanup where agreed.
If cleaning reveals cracked tiles, loose pointing, corrosion or damaged flashing, we show you the issue and quote repair separately. Australian-made treatment products are used where suitable, with the product and satisfaction guarantee terms set out in writing.

Straight answers, suitable materials and a clear written scope
Methods, inclusions, timing and price factors
Roof-cleaning pricing starts from $350 and can reach $1,800 or more. This is not a fixed price. We need to assess the roof size, pitch, access, material, coating condition and amount of growth before providing an accurate free quote.
No. The cleaning method is chosen after the roof material and surface condition are assessed. Pressure, soft washing or treatment may be used depending on the tiles, metal, coating, age and type of growth present.
Valleys, gutters, downpipes and cleanup can be included in the quoted scope. The quote identifies exactly which drainage areas and treatments are included so there is no assumption based on a general package.
Using the wrong pressure, angle or chemical on a fragile surface can cause damage. We assess the roof first and choose the method for the material and coating condition. Existing defects found during cleaning are shown to you and quoted separately if repair is needed.
There is no fixed schedule for every roof. Shade, trees, coastal exposure, roof material, pitch and drainage all affect how quickly growth returns. Clean the roof when buildup is affecting drainage or condition, and use inspection findings to plan the next clean.
The written quote explains the cleaning scope, product information and satisfaction guarantee terms. It also identifies any treatment included and its limitations, because future regrowth depends on the property environment as well as the completed clean.
