Does roof cleaning damage tiles?

Cleaning can damage tiles if someone blasts glaze and pointing with a turbo nozzle. VicWide soft-washes Melbourne terracotta and aged concrete. Damage is a method problem, not a reason to leave moss for another decade.

The short version

Cleaning can damage tiles if someone blasts glaze and pointing with a turbo nozzle. VicWide soft-washes Melbourne terracotta and aged concrete. Damage is a method problem, not a reason to leave moss for another decade.

What we actually see on Melbourne roofs

Terracotta glaze is a thin fire skin. High pressure cuts it and the tile then drinks water. That is why we default to soft wash on Camberwell and Kew streetscapes.

Concrete tile is tougher but old pointing is not. Pressure blows mortar out of ridges and creates the leak you were trying to avoid.

Lichen should be treated and lifted, not ground off. Grinding looks clean for a week and leaves scars forever.

If a quote is dramatically cheaper, ask what nozzle they use. Speed is how cowboy cleans get cheap.

We photograph chips that were already there so nobody argues later. Heritage matching is a roofing contractor’s job if units are broken.

A clean roof can reveal failed ridges. That is a feature. You want to see the problem before summer storms.

Local examples

Camberwell. High kerb-appeal cleans before listing. Profiles we wash: terracotta, concrete, complex hips.

Kew. Two-storey soft wash. Gutters under established trees. Profiles we wash: terracotta, slate, concrete on mid-century.

How this ties to the wash page

Soft wash is how VicWide cleans most Melbourne tile roofs: low pressure, the right dwell, no blasted glaze. Pressure has a place on some metal — not as a default on terracotta.

Priced as a proper clean, not a cheap blast. You are paying for the roof to survive the wash.
