Townhouse roof

[NAoZ]

Townhouse roof has a few spots that leaks on a heavy rain and I want to go up to patch and paint sealant for a quick fix.

Is it normally safe to stand on these roofs? It looks like a pretty standard roof around here but Im not sure what kind of material it is. Looks very similar to this, most turned gray and newer ones are in red. I think each panel is larger than the one in the photo.

House is close to 30yrs old so Im not sure if I can safely stand on it. Also do these usually contain asbestos?
