Do Attic Vents Help Cool House. For the best results place roof ventilation near the roof s peak and soffit vents in the eaves. Good insulation reduces fan effectiveness. These can be ridge vents wind turbines or the flat vents your roofer wants to install.
Unlike a ventilation fan a whole house fan an attic mounted fan that exhausts air from a home at night is designed to cool a house that is to lower the indoor temperature. Adding an attic fan can improve the airflow in your attic to keep it cool.
Air flows in through the soffit vents and out through the roof vents.
Attic fans push out the hot air and pull in the cool air from the vents installed on your roof. Because of this they require significant ventilation in the attic. Vents are often used in colder climates as a way to combat moisture retention. Whole house fans take all the hot air from the house and move it up into the attic and out through the attic vents.
