Walking on a colorbond roof is possible but risky — for the roof and for you. Here's what the manufacturers say, what the actual risks are, and how we clean two-storey colorbond roofs safely without roof walking.

Whether you can walk on a colorbond roof is a question that comes up frequently for two-storey home cleaning and for homeowners considering DIY roof inspection or maintenance. The short answer is that it's technically possible but comes with specific requirements to avoid damaging the roof, and for cleaning purposes we use extended reach soft wash equipment that avoids the need to walk on the roof surface entirely. This is better for the roof and significantly safer for the operator.
Bluescope Steel (manufacturer of Colorbond) advises that if foot access to a Colorbond roof is necessary, you should: only step on the ribs (the raised sections), not the pans (the flat sections between ribs); use soft-soled footwear; avoid concentrating weight in one spot; and take care not to scratch or gouge the surface. Walking on colorbond pans (the flat sections) risks permanent denting, which is irreversible.
The primary physical risks of walking on a colorbond roof are: denting the pans where weight is concentrated; scratching the paint surface, leading to corrosion points; and voiding Bluescope warranties if the roof is walked incorrectly. Beyond property damage, the personal safety risk is significant — colorbond is a smooth, potentially slippery surface, particularly when wet, and falls from roof height are genuinely dangerous.
For single and two-storey colorbond roofs, our soft wash equipment has sufficient reach to apply and rinse the cleaning solution from ground level or from appropriate ladder positions at the eave, without needing to walk on the roof surface. This approach is better for the roof — no denting risk, no scratch risk — and is significantly safer for our team.
For certain roof configurations, ridge cap cleaning or very large roofs, some roof access may be necessary. In these cases we use appropriate safety harnesses, soft-soled footwear and step only on the ribs — consistent with manufacturer requirements. We assess each roof's access requirements before starting.
Technically yes, but only on the ribs (raised sections) with soft-soled footwear. Walking on the pans (flat sections) risks permanent denting. For roof cleaning, extended reach soft wash equipment allows cleaning without roof walking in most cases.
Walking incorrectly — on the pans, in hard-soled footwear, or concentrating weight in one spot — can permanently dent and scratch colorbond. For cleaning purposes, avoid roof walking where possible.
Yes — in most cases. Professional soft wash equipment with extended reach can apply and rinse cleaning solution from ladder positions at the eave, avoiding the need to walk the roof surface.
Low-pressure soft wash solution applied and rinsed at 50 to 100psi, using extended reach equipment from ladder positions where possible. Where roof access is necessary, appropriate safety harnesses and soft-soled footwear on rib sections only.
