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
asbestos garage roof before I crack the panels. The panels are
supported on wood beams about every 5 feet.

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.
Instead, use a ladder or staging to get into a position where you can
remove the moss with a pressure washer. Otherwise, don't bother.
If you insist on going ahead with your plank idea, you should call the
ambulance before starting work.
do not use a pressure washer!

If the OP wasn't so long ago, I'd suggest putting a ladder flat across
the roof and a plank onto that.

But he's probably died of mesothelioma by now...


Or had a heart attck when he got the 'experts' in to remove it and
saw their bill.
