The difference in styles between residential and commercial construction is probably an example of this. Not many commercial buildings with tar paper shingled roofs.

I mean, this is kind of true and kind of untrue. There aren't a lot of commercial roofs with literal residential asphalt shingles, but many commercial roofs are things like mod bit which are practically the same concept, just a mod bit needs to handle an extremely low to flat pitch while residential shingles assume a decent pitch to the roof. Tons are also just single-ply membranes, which often don't even last as long as a good residential asphalt shingle install.
Its not like every commercial building has a metal roof. Just look at this random commercial/industrial office park:

Take a look around. You see a lot of metal roofs, yes. You also see membrane roofs. You see mod bit. And you'll even see some old built-up roofs.
For a business, it can make more sense as it might be a more long term structure, plus it would contain more valuable items (or at least cause more loss if business is interrupted).
Also noise, if you live somewhere with a lot of rain.
I wonder if the longevity argument really holds, too. Anecdotally, our local public housing project invested in metal roofs many years ago (less than 30, however) but a good fraction of them have been replaced since with contemporary asphalt shingles. I do not know why they failed, but the switch back to asphalt says something.
AKA "I'll be gone. You'll be gone."
Metal roofs will also last a lot longer. Their color may not, but the roof itself, as long as it was installed properly (major component here), will outlast asphalt by decades.
There's probably a bit of selection bias in both directions: metal roofs that don't work get replaced with shingles and are no longer metal roofs, while metal roofs that do work have owners that don't think about them much and don't complain about them.
