I need to get up on the roof of my garage to remove the moss. I
don't have a feel for how much imposed weight I can put on a typical

If I put up a couple of planks to spread my weight across two beams
would that be enough do you think?

I weigh 100kg clothed.

No chance. Not only is asbestos cement weak and brittle, but there is
the danger from asbestos fibres when it breaks, as it surely will with
any weight on it.

oh no! not the "asbestos cement DANGER DANGER" thread again I hope
Bruce?!

from wiki - to save the bandwidth:-

"Asbestos exposure becomes a health concern when high concentrations
of asbestos fibers are inhaled over a long time period.[23] 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.[23] Smoking
combined with asbestos exposure may increase the health risk
dramatically"

One fibre can kill. Painful death from mesothelioma.

Utter utter nonsense. You do realise that asbestos fibres are everywhere,
don't you? Normal exposure won't kill you.
