My garage roof is made of corrugated asbestos, probably "asbestos

fibres get released and basically I need to hire some asbestos
professionals?

A pal disposed of an old asbestos panel Uni-Seco prefab building a while
back. A builder had been charged thousands by a specialist removal company
to dismantle a similar one nearby so he just dug a bloody great hole with a
JCB and pushed it in. He did limit his exposure by soaking everything first,
wearing a fairly sophisticated mask, and dumping his overalls in the final
part of the hole.

I spent some time building those garages, I was quite often the person
standing underneath while the holes were being drilled to accept the
roof bolts

Asbestos cement really isn't that dangerous compared with other
varieties



"Asbestos exposure becomes a health concern when high concentrations of
asbestos fibers are inhaled over a long time period.[30] People who
become ill from inhaling asbestos are often those who are exposed on a
day-to-day basis in a job where they worked directly with the material.
As a person's exposure to fibers increases, because of being exposed to
higher concentrations of fibers and/or by being exposed for a longer
time, then that person's risk of disease also increases. Disease is very
unlikely to result from a single, high-level exposure, or from a short
period of exposure to lower levels.[30]"

I suppose I fall into that category, but I don't lose sleep over it.
Someone breaking up a roof once in their life really shouldn't be that
concerned
