Install A Range Hood Roof Vent

It is easier to install equipment when you disassemble its parts.

Install a range hood roof vent.

On the roof use a jigsaw to cut a round hole. Slide the vent under the shingles so they cover the top half of the vent flange. Measure out a square that s slightly larger than the vent hole and remove the shingles in this area with a hooked blade. Before you purchase a range hood check the cfm rating of its fan.

We would love to install a vent hood but don t know how to vent it. Disassemble the range hood vent into its units. Any help would be greatly appreciated. Ensure that the spots you mark out on the ceiling are precise.

We have a gas range built into a center island with a downdraft vent that doesn t vent well. Range hood installation can involve drilling a new vent hole through a wall which can require new wiring and ductwork while replacing old ones can be a simpler process. Apply a bead of asphalt roof cement on the bottom of the vent. Mark out spots on the ceiling.

The lower half of the flange sits on top of the shingles. After the hole is cut in remove the roofing shingles on both sides of the roof opening and at least 3 rows above the opening. If the hole saw can t cut through the interior wall in one pass stop cutting remove the plaster from the hole and continue drilling. Nail the lower corners with roofing nails and tar the heads.

Once you drill the hole you will need to cut an adequately sized opening to fit the range hood vent either square or a round shaped one depending on the design of your roof vent. Step 2 before you begin cutting a large hole into the wall to install the vent first cut a smaller hole to see what s behind the wall. Measure the range hood to determine where the vent comes out on the range hood and mark it on the wall. The ductwork should already be punched through the ceiling and above cabinet or back wall and ready to hook up to the range hood before beginning installation.

The trickiest part of installing a range hood is determining how to run the ventilation ducts. Right above where our range is is a upstairs bedroom which prohibits going through the roof. This should be between two rafters. Depending on the location of your range you will need to decide if it is easier to vent through an outside wall versus up through the roof.

Use this tutorial if you determine that venting through the roof is the best route. Install the proper sized ductwork and exterior roof or wall cap depending on where you will be venting your hood to the exterior. Collect the dust with wet dry vacuum while cutting the hole. Process beginning in the attic drill a hole through the roof where you want your vent to go.
