How To Ventilate Attic Soffits

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.

How to ventilate attic soffits.

Air flows in through the soffit vents and out through the roof vents. The soffit vents allow convective air movement from the soffits of the residence to the ridge vent. Normal vented air likes to enter the attic lower down near the bottom third of the attic and as it passes through it will exit higher up near the top third of the attic space. Grab a flashlight and inspect your attic during the winter.

The main idea of the ridge vent is to act together with soffit venting to properly ventilate the attic. For the best results place roof ventilation near the roof s peak and soffit vents in the eaves. Typically you would have a gable vent on each end of the attic. The soffit vents are now installed but you still need to make sure there s no insulation blocking the new vents.

If you see dampness or frost you need better roof ventilation and some attic vents. For an attic without soffit vents you may have the option to use gable vents instead. If the attic is insulated with fiberglass batts just pull back any that are blocking the flow of air.
