Roof Cleaning Wollongong
ClearView Exterior Services provides safe, effective roof cleaning across Wollongong and the Illawarra. We use a low-pressure treatment approach to remove moss, lichen and staining from terracotta-tile and Colorbond roofs — without high-pressure blasting.
Professional Roof Cleaning You Can Rely On
Moss, lichen and black staining don't just look bad — they can hold moisture against your roof surface and contribute to long-term deterioration. ClearView Exterior Services offers safe roof cleaning throughout Wollongong and the Illawarra using a method designed to protect your roof, not damage it. Whether you call it roof cleaning or roof washing, the goal is the same: remove the growth without damaging the roof.
We don't use high-pressure blasting on roofs. Instead, we use a low-pressure treatment approach — securely positioning access equipment, then applying an appropriate treatment from above using a long bent wand, working from the top of the roof downward. This removes organic growth and staining without forcing water under tiles or damaging the surface.
Access and roof condition are assessed first. Not every roof is suitable for cleaning — if the tiles are too fragile, the coating is failing, or safe access can't be achieved, we'll tell you honestly before we start.

Surfaces We Handle
We assess roof material, condition and safe access before recommending treatment. Our roof-cleaning service addresses suitable surfaces and the following types of build-up:
Our Low-Pressure Roof Cleaning Process
We follow a step-by-step approach to deliver consistent results on every job.
Assess Access and Condition
We inspect the roof type, condition, pitch and access. If the roof is too fragile or access is unsafe, we'll tell you before starting.
Position Access Equipment
We securely position access equipment to safely reach the roof without unnecessary walking on the surface.
Apply Low-Pressure Treatment
Using a long bent treatment wand, we apply the appropriate treatment from the top of the roof downward, controlling runoff.
Allow Treatment to Work
The treatment breaks down moss, lichen and staining at the root — this is what makes the result longer-lasting than pressure alone.
Rinse at Low Pressure
We rinse the roof at low pressure to remove the broken-down growth and staining without forcing water under tiles.
Inspect and Tidy
We inspect the result, check gutters and downpipes for debris, and tidy the site.
