Everything is double bagged inside the containment.

Bit OTT for an asbestos cement roof which is probably white asbestos
and relatively safe compared to blue or brown. Bashing it up with
hammers or angle grinding into manageable bits with no attempt at
dust control or breathing protection is at the other extreme though.

It is asbestos cement - it can be removed without any particular
precautions other than minimising dust by wetting it well. It does
not require a licenced asbestos fraudster to do the job.
