I guess it depends on what materials your roof is made from. I have a lot of gal steel used in my roof; my guttering and downpipes are made from the same material. If there was micrometeorite material in the runoff, it would be heavily polluted with contaminants, so I guess I'd be looking for the proverbial needle-in-the haystack …
Separating the real stuff from the pollutant would be the main issue .. (ie: deciding what to send to the labs would be the main issue …??...)

That's were a magnet comes into good use Craig.
If you were getting galavanized material plus bare metal in the contamination, I think a new roof would be in order.
