How to ventilate attic soffits.

If the attic is insulated with fiberglass batts just pull back any that are blocking the flow of air. The soffit vents are now installed but you still need to make sure there s no insulation blocking the new vents. For an attic without soffit vents you may have the option to use gable vents instead. The main idea of the ridge vent is to act together with soffit venting to properly ventilate the attic.

An attic s intake vents are most commonly installed directly in the soffit either as individual vents spaced every few feet or as one continuous perforated soffit running the entire length of. If you see dampness or frost you need better roof ventilation and some attic vents. Air flows in through the soffit vents and out through the roof vents. In addition insulation baffles must be installed at the point where the attic floor meets the roofline to prevent the attic insulation from migrating into the cavities and restricting the airflow from the soffit vents.

Vents come in various styles. Typically you would have a gable vent on each end of the attic. When hot air rises up through the soffit venting it then keeps rising all the way up to the ridge vent.
