How do you identify asbestos in roofing sheets?

When working with older roofing sheets, it's important to know if they contain asbestos. There can be serious health and environmental consequences if asbestos-containing sheets are damaged or mishandled.

Methods to check for asbestos

Embossing number: The number embossed on the outside of the sheet reveals whether it contains asbestos (see table above).
Analyse: If the number is missing or there is uncertainty, you can send a sample to a lab for a professional assessment.
