How to Install a Roof Vent

Inadequate ventilation can cause roofing material in your home to deteriorate. The addition of roof vents increases the air flow and can extend the life of your tiles. Substantial money can be saved by installing ventilation ducts. Homeowners who have had some experience in roof repair can save even more money by installing the same vents.

Instructions

  1. Set up an extension ladder on the side of the house and go up to the roof.
  2. Look for the ridge line; this is the angle at which the two sides of the roof meet.
  3. Look for frames, which are triangular wooden structures that are used to support the roof, with the beam detector.
  4. Measure 3 feet from the center of the ridge line, centered between two roof beams. Hammer a roofing nail into the roof to mark the center of the area where the vent will be installed.
  5. Measure the area of ​​the guide holes by using the nail as your center point. Drill a hole in each mark.
  6. Cut through the roof and plywood with skill saw. Make your cut following the marked guide holes. Keep the nail in the center to catch the cut piece when it is about to fall.
  7. Remove the shingles cut and felt with a roofing knife all the way around the edges of the new hole.
  8. Apply a generous layer of roofing sealant around the cut hole where the vent will sit.
  9. Place the vent grill over the hole and center it. Nail the top, sides and bottom of the ventilation grill on the roof with roofing nails. Make sure that the tiles are placed on the flange of the ventilation grill.
  10. Caulk all the nail heads and open seams around the vent.
