Yes, I disagree.

Glass roofing would be the least toxic choice. It's chemically inert and  
lasts forever.

As for the study, although I didn't have a real close look at it, from  
what I did see, it struck me as being one that I'd not be inclined to lend  
much credence to.

I can't help but have the suspicion that the study was bought and paid for  
by stakeholders who have something to lose by the increasing market share  
that metal roofing is taking away from ... well, you know.
