Signs it may be asbestos-cement
- Rigid corrugated sheets, grey or whitish, often with moss and lichen
- Building constructed or roofed before the late 1990s
- Rough, porous, brittle surface that flakes
- Gutters, pipes or tanks in grey cement-like material
- Building documents mentioning asbestos-cement
Is asbestos-cement the same as asbestos?
Not exactly. Asbestos-cement is cement reinforced with fibres. For many years those fibres were asbestos; later, synthetic or organic fibres were used. Old asbestos-cement should therefore be presumed to contain asbestos until proven otherwise.
How to confirm for certain
- 01Do not collect samples unprotected — breaking or scraping releases fibres.
- 02Contact a specialist company or accredited laboratory for sampling and analysis.
- 03With the result, decide the best solution: monitoring, encapsulation or removal.
I know it has asbestos. Now what?
AV Metal does the site visit, provides a quote and carries out the asbestos removal and new roof. You can also learn how the process works, step by step.
Frequently asked questions
How do I know if my roof sheets contain asbestos?
Old asbestos-cement sheets should be treated as containing asbestos until analysis proves otherwise.
Is there asbestos-cement without asbestos?
Yes — sheets made after the ban use other fibres. Only analysis or manufacturer documentation can confirm.
Can I send a sample for analysis myself?
You should avoid it. Sampling can release fibres. Ask a specialist company or laboratory.
