How to Install Soffit Vents

By: Danny Lipford

soffit-vents

Adding soffit vents introduces cool, fresh air to your attic as hot air escapes from the top of the attic through ridge vents, attic fans or gable vents. This project is easy to handle yourself and will help bring down the cooling costs for your home.

  1. Measure the area where you want to install the vents and determine how many will be needed along each section.
  2. Cut a piece of wood slightly smaller than the size of the vent you’re installing and use that as a template to mark the cut lines for each location. It should be an inch shorter and an inch narrower than the actual vent.
  3. Cut the hole using a circular or saber saw. Check to make sure that nothing is blocking the hole, and remove any insulation that might be covering it from within the attic.
  4. Center each soffit vent over the hole and parallel to the eaves with the vent louvers facing in toward the house before you screw each vent to the soffit board.
  5. Paint the vent to match the soffit.

Adding soffit vents introduces cool, fresh air to your attic as hot air escapes from the top of the attic through ridge vents, attic fans or gable vents. This project is easy to handle yourself and will help bring down the cooling costs for your home.

Measure the area where you want to install the vents and determine how many will be needed along each section. Cut a piece of wood slightly smaller than the size of the vent you’re installing and use that as a template to mark the cut lines for each location. It should be an inch shorter and an inch narrower than the actual vent. Cut the hole using a circular or saber saw. Check to make sure that nothing is blocking the hole, and remove any insulation that might be covering it from within the attic. Center each soffit vent over the hole and parallel to the eaves with the vent louvers facing in toward the house before you screw each vent to the soffit board. Once you paint the vent to match the soffit, no one will notice it’s there, except you and your utility bill.

    Danny,
    I have replaced approximately half of the soffit vents on my home recently. I placed the vent louvers facing away from the house. Last Saturday morning I saw the portion of the show where you were replacing soffit vents and it appeared that the vent louvers were facing in toward the house. My question is the reason the vent louvers should face in toward the house instead of away from the house. I thought that with the louvers facing away from the house more air flow could go into the attic from any wind or breeze if the louvers were facing away from the home. I have about 20 more to replace and want to install them in the right position. I will remove and reinstall those those that I had replaced if there is a good reason to place the louvers of the soffit vents facing in toward the house.

    Thank you. Enjoy your show!

    I have lived in my home for 19 years, it’s time to start replacing windows. I am torn between selecting window world and Lansing windows. What is the difference in the quality? Window world would not give me the addresses of any of their clients. The one house we did see we were not impressed with the workmanship. Is it a good idea to have windows wrapped in vinyl? All of our windows were wood and we just spent 25,000 replacing masonite siding and replacing with hardiplank. Please give us you honest opinion. We live in Cary, NC and considering getting windows with the solar zone with argon gas. Solar zone Glass U=0.9 SHGC=0.30
