We just purchased a 4 yr old home with Hardiplank on the exterior walls.
It currently has a "vent" over the stove, which only blows the smoke
around, and is not vented to the outside. Can this be properly vented
through the exterior wall, or must it be vented through the roof, and,
what kind of licensed contractor should I get estimates from?

Its ductwork, get a "ventilation" specialist. Depending on how old the
vent hood is, there may or may not be additional hardware needed to
redirect the air flow "up and out" instead of "forward through the
filter." For sure, you will need a barometric damper to close the vent
stack when its not on. If you are lucky, the pieces didn't get tossed
into the installer's stash box.
