An attic is more than just a storage place. It also helps control temperatures in the house by providing consistent airflow. A well-ventilated attic makes sure that you get the most out of your roof, keeps your energy bills down, and helps the roof last as long as possible. Your local roofing contractor discusses more below.
How Ventilation in the Attic Works
The main role of proper ventilation is to allow cool, fresh air into the attic space and let moist, stale air escape. To accomplish this, the ventilation should be placed at the soffits or eaves and at the top peak, called the ridge, of the attic room. This will encourage sufficient air circulation, which will keep the attic space at a uniform temperature and humidity levels, no matter the season.
The Importance of Balanced Ventilation
When intake and exhaust allow for the same amount of airflow, creating a push-pull effect around the roofing system, it is considered balanced ventilation. Without proper exhaust ventilation, hot and stale air cannot get out. Without proper intake ventilation, air will only move around across the top of the attic, leaving air stagnant at the bottom of the room.
How Attic Ventilation Keeps Cooling Costs Low
Since it is natural for hot air to rise, it will eventually make its way into the attic, and it will remain there if the room is not adequately ventilated. On a 90° day, temperatures in the attic can reach 140° or higher. This unventilated air can find its way back into the living spaces, causing fans and air conditioning units in lower levels to work harder to maintain a comfortable temperature.
In a standard-sized home, cooling accounts for 6% of the total utility costs. If there is proper ventilation, warm air can find its way up and out of the house instead of being trapped in the attic.
