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

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.

Did the roof of my house from a ladder, with standoff, using a long-handled
dutch hoe.
