Range venting through roof vs wall.

The range hood vent uses ducts that are made to run in the roof or walls. It is considered a little more expensive to vent your range hood through the roof than through the wall. That length gets shorter the more bends you have in the vent piping. The more things that you have sticking through the roof the more potential that you have for a leak.

Many times your choice depends on where your range is located. But first we should explain to you how it works. A wall vent comes with efficient filters and exhausts and is built to fit in kitchen walls with the exhaust installed on the external wall of the house. For homeowners who prefer an inconspicuous vent a roof vent is a better choice.

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. While this can be done through the ceiling and out through the roof it s best to go through an outside wall because there s less need for waterproofing. They must withstand a complete temperature range as well as damage from the sun wind branches or even hailstones. This is why you need to install the range hood vent properly or you call a roofing contractor.

In either case do not vent into the wall or the attic. In the case of the roof some venting is unavoidable in order to provide attic circulation so choose roof vents that are durable and watertight. As for the walls rainscreen compatible intake and exhaust vents are now available. Be sure to extend the pipe up at least 2 to 3 above the roof to prevent snow buildup from causing problems.

You should also check the install instructions as there should be something in there about maximum length of ducting if you are considering going out the wall. If you decide to vent through the roof go all the way out to clear air through the roof and don t just vent it into the attic. This is the most budget friendly type and among the simplest to install.
