Older homes often have asbestos-containing Fibrolite roofing, which requires a completely different approach to treatment than standard metal or tile roofs. Disturbing these surfaces incorrectly carries real risk — both to the roof itself and to those working on it — which is why many roofing contractors won’t touch this roof type at all.
We’ve built specialist expertise in treating asbestos-cement roofs safely, following strict low-disturbance methods that clean and protect the roof without compromising the material. It’s a service that requires the right training and equipment to do properly, and one we’ve made a core part of what we offer.
Asbestos-cement roofing behaves differently to modern materials, and treating it the wrong way can create serious problems.
high-pressure washing can disturb the asbestos-cement surface, releasing fibres that pose a health risk.
older Fibrolite roofs are more brittle than modern roofing, making them easy to damage with the wrong method.
many roofing companies avoid asbestos roofs altogether, leaving homeowners with few safe treatment options.
Left untreated because of this gap, moss and lichen continue to build up on these roofs unchecked, even though they can be treated safely with the right approach.
Rather than treating an asbestos roof the same way as any other, we follow a specific process built around safety at every step.
We assess the roof’s condition and confirm the safest treatment approach before any work begins, rather than applying a standard method by default.
We apply our low-pressure treatment using strict low-disturbance methods, cleaning and protecting the roof without compromising the asbestos-cement material.
our low-pressure method won’t scratch or damage panel surfaces the way abrasive cleaning tools can.
a service most roof treatment companies avoid, backed by the training to do it properly.
the exact approach that risks disturbing asbestos surfaces and releasing fibres.
a fully insured team with experience treating asbestos and Fibrolite roofs safely.
Yes, when done using the correct low-disturbance methods. The risk comes from incorrect approaches like high-pressure washing, not from treatment itself.
It requires specific training and low-disturbance methods most standard roofing contractors aren't equipped for, so many avoid it altogether.
No. Our low-pressure, low-disturbance method is specifically chosen to clean and protect the roof without compromising the surface.
Older homes with a distinctive flat or lightly corrugated cement-style roof often fall into this category — we can confirm this as part of your free assessment.
Yes — the same two-stage approach applies, using methods adapted specifically for asbestos-cement surfaces.
We are committed to delivering exceptional roof cleaning services that protect your property and enhance its appearance.
