What is the best way to ventilate an attic?

Also question is, what is the best attic ventilation?

Static, roof-line, vents are effective for ventilation but generally aren't recommended due to issues with leaks. Soffit vents may leave air trapped at the top of your attic. Most effective ventilation uses a ridge-and-soffit continuous ventilation system, but even these designs can vary from roof to roof.

Additionally, what happens if attic is not vented? As we've learned, the biggest problem with not having proper attic ventilation is moisture. And if you don't vent correctly, all that warm, wet heat is going to sit around and take up space in your attic.

Also asked, how much ventilation is needed in an attic?

The general rule of thumb on the amount of total attic vent space needed is to have at least one square foot of vent space for every 150 square feet of attic area.

How do you tell if your attic is properly ventilated?

Here are four signs of an unventilated or under ventilated attic:

1. Look at your eaves and roof.
2. Touch your ceiling on a warm, sunny day.
3. Thick ridges of ice on your eaves in winter are a sign of poor attic ventilation.
