How to Install a Roof Vent

Roof vents can help exhaust moisture from inside your home due to a kitchen, bathroom, laundry room, and more. Luckily, these vents are easy to find (at your local home improvement store) and easy to install using just a few tools. Here, our roofing repair experts share the steps you’ll need to install your roof vent:

What you’ll need to install a roof vent:¬†roofing repair

  • Drill, drill bit
  • Ladder
  • Roof vent
  • Ruler
  • Marking pencil
  • Hammer, nails
  • Jigsaw or reciprocating saw
  • Pry bar
  1. First, head up to your attic and determine where you want to install your roof vent.
  2. Drill a hole upward through the middle of the area you desire and leave the drill bit sticking up through the roof so you can find it from the outside.
  3. Next, position your ladder against your home and climb up to your roof.
  4. Locate the drill bit.
  5. Using your ruler, measure the open area of the vent (the part that will sit flush with your roof).
  6. Next, using your drill bit as your center, use your ruler and a marking pencil to measure the same size space onto your roof.
  7. Use your jigsaw or reciprocating saw to cut along the measured lines. Cut through both your shingles and the wood underneath.
  8. After that, use your pry bar to loosen the shingles surrounding the hole.
  9. Turn your vent upside down and apply a thick bead of caulk to the flange.
  10. Slide the top and sides of your vent underneath the surrounding shingles and leave the bottom side of the vent exposed and laying over the shingles.
  11. Next, hammer in a nail every few inches to secure the vent to your roofing structure.
  12. Secure any loose shingles around the area with nails.
  13. Repeat steps 1-13 for any other roofing vents you’d like to install.
