susceptibility to falling avocados...?

I've got a precious avocado tree that largely overhangs our house (and let me add right off that pruning it back isn't an acceptable solution.) I just want to know where falling avocados would fall in the spectrum of "might-damage," "definitely-going-to-damage," "probably won't damage" (etc), if I go with any standard-gauge standing-seam (or other pattern, for that matter) metal roof.

We're in Hawaii, and the steel roofing supplier tells me that there's seldom if ever a need for anything more than underlayment below the metal, so it would essentially be solidly backed by 5/8" ply.

Avocados are up to the large side, prolly averaging about a pound, and they often are not terribly damaged themselves by the fall, though we sometimes get rude awakenings during the season. The highest overhanging avocados are around 20' above the roof.

Forget metal? Do some bizarre testing?

So get a sample metal panel, put it on the ground and drop avocados on it.
