The Under Eave Vent is an air intake roof vent. To clarify, Soffit Vents are roof vents that go underneath the eaves of a roof that extend the warm wall line. When properly combined with other roof ventilation devices, soffit vents allow fresh air to enter into an attic to create proper airflow.

Important: when used in combination with intake vents that sit at the bottom of your roof line (like a soffit vent), a ridge vent offers the best chance for vertical ventilation. Vertical ventilation takes advantage of gravity and the natural flow of cool and hot air. Cold air comes up through the bottom, and exits through the top.

Natural Attic Ventilation

Here's why: in the winter, allowing a natural flow of outdoor air to ventilate the attic helps keep it cold, which reduces the potential for ice damming (snow that melts off a roof from an attic that is too warm and then re-freezes at the gutters, causing an ice dam that can damage the roof).

Rafter vents, often called baffles protect intake vents in your attic from becoming clogged or covered by insulation or debris. Rafter vents ensure the soffit vents are clear and there is a channel for outside air to move into the attic at the soffits and out through roof vents.Jul 18, 2017

Covering the roof vents means you're unwittingly trapping moisture within the attic space.

Ridge vents are incredibly common, as they’re very easy to install as a part of the original roof ridge. A ridge vent is a space under the ridge where air is able to escape from the attic below. Combined with a good intake vent, ridge vents let hot air be pushed up and out of the structure.

Roof vents that are designed to remove the air in the attic are to be installed near the peak. If additional roof vents are installed below the vents near the peak than they will most likely become an intake. In most cases intakes need to be installed below the roof eaves.

If you stand in your back yard and look up at your roof, you may notice a series of vents along the ridge line. They looks like mushrooms — with a wide top and narrow, hidden stem.
