How do you vent a range hood on a roof?

Installing a Vent Hood on the Roof

Range hoods are typically vented using a special duct work that runs through a roof, and less often, through an exterior wall of your house. The duct work is usually concealed within the walls, and it is really important to make everything air and water tight.

Furthermore, how far can you run a range hood vent? For optimum performance, make sure that the air duct is short and straight, with a maximum length of 50 linear feet. Long radius elbows are preferred to short radius elbows for better air intake. Note: Each elbow is equivalent to 10 linear feet of duct. Be sure to also install a wall or roof cap.
