How Does Roof Vents Work

All things being equal wind driven turbine vents also known as a whirlybird roof vent do move more air than flat vents but only when the wind blows.

How does roof vents work.

Intake vents located at the lowest part of the roof under the eaves allow cool air to enter the attic. There are two primary methods to create air flow within an attic. The vent pipes also allow oxygen into the waste pipes. Requires a power source.

The goal is to keep the attic space in your home dry and cool. Roof ventilation works by allowing air to flow through the attic which prevents it from becoming overheated and causing moisture. The vent stack is the pipe leading to the main roof vent. The vents also keep the air pressure the same on both sides of the trap.

This enables bacteria to break down the sewage aerobically meaning by the use of oxygen. Static roof line vents are effective for ventilation but generally aren t recommended due to issues with leaks. Wind driven roof vents will pull more air from the attic but only when the wind is blowing. It channels the exhaust gases to the vent and helps maintain proper atmospheric pressure in the waste system.

The vent pipes allow the sewer gases to escape to the outside rather than being released inside the house. Roof ventilation works to keep warm air and moisture out of the attic. These attic vents let out hot air like other types of vents but when the wind blows it pumps out even more hot air and this happens without using and electricity like a power attic fan. Attic ventilation works on the principle that heated air naturally rises primarily utilizing two types of vents.

A roof ventilation system works by providing a continual flow of air through the attic space helping remove overheated air and moisture from the attic and roof system and reduce the impact of changing temperatures and moisture conditions both inside and outside the home. Drip edge vents are a two in one installation that promote water shedding at the eaves and rakes of a roof while also allowing for ventilation into the attic. Most effective ventilation uses a ridge and soffit continuous ventilation system but even these designs can vary from roof to roof. Ventilation only works when air flows.

A drip edge vent is made of a corrosive resistant material that sticks out about three inches back from the roof edge and then bends downward over them. It is a vertical pipe attached to a drain line and runs through the roof of your home. This will prevent black mold from growing in your attic keep your plywood from failing and help your shingles last as long as possible.
