How Much Ventilation Does Your Attic Need?

How Much Ventilation Does Your Attic Need?

For every 300 square feet of attic space, at least one square foot of ventilation is required. As a result, the normal attic area to attic ventilation ratio is 300:1. Exhaust vents should account for half of your ventilation, while intake vents should account for half. In New Jersey, laws for attics have some considerable relief to use for residential purposes; Parsippany, NJ, also lets you occupy an attic.

Multiply the length by the width to get the square footage of your attic. If your attic is 20 feet by 60 feet, for example, it has a total space of 1,200 square feet. Take that amount and multiply it by 300. That means you’ll need 4 feet of ventilation for a 1,200-square-foot attic. The intake vents should be half of those (2) feet, and the exhaust vents should be the other two feet; AC installation is connected to the attic.

How To Tell If Your Attic Is Well Ventilated?

If you want to see if your attic has proper ventilation, you have a few options. These simple tests might provide important information about your attic and home:

  • Ceiling Temperature: Your attic is too warm and not getting adequate ventilation if your ceiling feels hot to the touch. Because your air conditioner is working overtime, your energy expenses are probably higher than they need to be. Furthermore, your shingles are most likely getting hot, which could cause your roof to disintegrate.
  • Smoke Test: On a non-windy day, conduct a smoke test with incense, a match, and a flashlight to learn how the air travels. Observe how smoke moves in and out of your attic to obtain a good ventilation picture.
  • Frost In Winter: If you observe frost or wetness in your attic during the winter, it means warm air is escaping from your home’s rooms. Moisture is condensing on the sheathing or rafters of your roof.
  • Temperature Difference: Is there a room in your house that is consistently cooler or hotter than others? Poor attic ventilation may be to blame. You might also call a local insulation contractor to determine whether your home could benefit from additional insulation.
  • Air Conditioner Is Working in Overdrive: If you don’t have adequate ventilation, your air conditioning system may work harder to keep your home cool. If your air conditioner seems to run constantly or breaks down more frequently, it could indicate that you need additional attic ventilation. This could result in additional costs.

Why Is Attic Ventilation Significant?

  • Assists in extending the life of your roof
  • Ice dams, interior leaks, and roof damage are all avoided
  • Keep your home at a more pleasant temperature
  • Lowers your energy bills
  • Mildew, rusted nails, wood rot, and degradation in the attic are all reduced
  • Prevents shingles from burning in the summer and causing the roof to deteriorate
  • Assists in the maintenance of roof warranties

Increasing the amount of ventilation in your attic can save you a lot of money. While you can install vents and fans yourself, keep in mind certain safety considerations. Working on high ladders is risky, and exposing yourself to insulation can harm your health. We suggest hiring our AC repair in Parsippany if you reside in the area. Have our experts handle the most difficult tasks of the job. Some homes are more difficult to ventilate than others, which is another reason to hire our professionals.
