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.

I used to walk all over my dad's garage roof
which was very rusty metal
by always putting my foot on a nail,
cos under the nails were rafters.
