Range hood vent roof or wall.
The range hood vent uses ducts that are made to run in the roof or walls.
Straight up to roof or vent out of wall.
It is considered a little more expensive to vent your range hood through the roof than through the wall.

This is why you need to install the range hood vent properly or you call a roofing contractor.
