I would tag that as:

amenity=shelter
building=roof        ( <— this tag is really the point of the thread)

I would not use `amenity=shelter` at all and instead tag those as 
https://wiki.openstreetmap.org/wiki/Tag:highway=bus_stop <https://wiki.openstreetmap.org/wiki/Tag:highway=bus_stop>

highway=bus_stop
public_transport=platform
bus=yes
shelter=yes
bench=yes

Anything that should show up on a 3D map needs a `building` tag and maybe a `height`.

In iD, the things we provide as presets, and how we render those things on the screen influence how people map.

It sounds like from the discussion that we should not assume that shelters are buildings, and instead provide a field so that mappers can decide.  Once we provide this field, we can expect a lot of people to use it.  (I’m trying to engage the tagging list a lot more so that people feel consulted when I change things in iD.)

Thanks, Bryan
