Attic Vents Purpose

The goal is to have a uniform flow of cool air from the outside through the attic and out the exhaust carrying the hot moist air in the attic with it.

Attic vents purpose. These vents work great along with the roof ridge vent which i have an article on and i encourage you to watch that one as well. Just as drain pipes remove water and waste from your home the plumbing vent pipe also known as a plumbing air vent removes gas and odors. Lowering the temperature in the attic can help reduce air conditioning energy costs and roof deck temperature optimize the service life of a roof covering and minimize ice damming. In cold climates the primary purpose of attic or roof ventilation is to maintain a cold roof temperature to control ice dams created by melting snow and to vent moisture that moves from the conditioned space to the attic ventilation acts to bypass the vapour barrier created by most roof membranes.

It also allows fresh air into the plumbing system to help water flow smoothly through the drain pipes however no water runs through the plumbing vent pipe. The plumbing vent also known as a vent stack helps regulate the air pressure in your plumbing system. The purpose of these vents is to keep air circulating in the attic which helps control ice dams in winter prevents overheating in summer and controls moisture all year long. Attic ventilation serves two main functions.

This allows for the hot and humid air that has built up inside your attic to escape out of your other vents. To lower attic temperatures and to remove excess moisture.
