While this isn't designed to protect from falling objects, it's appears tough enough to protect from the odd small falling object, not really a problem where I am. As to how far above the ROPS- the mounting system is totally adjustable so you can mount it probably up to a foot above the ROPS or even below and in front of the ROPS. I mounted mine even with the top for appearance and it seemed to be the proper headroom for me. I was probably a bit harsh on the mounting system, considering how easy it was to put on and how much flexibility it gives you.
