Looks to me that the flooring would be very hard on my hands and knees over the distance ...

ever since I was a little kid (and that is a looong time ago) I have had a recurring dream of falling off the NE corner of the two story house I grew up in ... never been on that roof tho, not sure why the dream.

Even climbing the stairs on fire tower lookout make me nervous, being on the platform not so much, but that open climb ...
