How to ventilate attic soffits.

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. Vents come in various styles. When hot air rises up through the soffit venting it then keeps rising all the way up to the ridge vent. 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. The soffit vents allow convective air movement from the soffits of the residence to the ridge vent. Air flows in through the soffit vents and out through the roof vents. Grab a flashlight and inspect your attic during the winter.

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. For an attic without soffit vents you may have the option to use gable vents instead. If you see dampness or frost you need better roof ventilation and some attic vents.
