Black staining, moss or lichen can leave a roof looking tired. We inspect the surface first, then recommend pressure cleaning or our gentler Spray & Wait treatment.

We'll assess your roof at no cost

Sydney's climate is tough on roofs. Heat, humidity, and regular rainfall create perfect conditions for moss, lichen, and algae to thrive. Over time, your roof becomes an eyesore—and these organisms can actually damage your tiles if left unchecked.
Roof cleaning can lift built-up dirt and treat organic growth, but the method matters. We use controlled pressure cleaning where the roof is suitable or our exclusive Spray & Wait treatment, we remove every trace of growth and treat your roof to prevent regrowth.
RoofingCorp has worked on Sydney roofs since 1994. We inspect the roof first, protect the surrounding property and explain what result to expect from the selected method.
We assess common roof growth, staining and debris, then choose a suitable way to remove or treat it.
