Everything You Need to Know About Attic and Roof Ventilation
We all understand the importance of a healthy roof for keeping a home in great condition. But what’s one often overlooked area that plays a huge role in a roof’s performance and efficiency? Ventilation. Here, we’ll go over how to determine whether you need better roof and attic ventilation. Why is Good Ventilation So Important? When we refer to roof ventilation, we’re not talking about anything complicated or mysterious. We still mean airflow, or circulation. Roof ventilation requires consistent airflow to function properly. This is typically achieved mechanically, through a power source, or naturally, using the stack effect or the wind effect. The stack effect occurs when hot air rises and creates pressure in the attic. In order to avoid growing too hot, the hot air, known as exhaust, needs a means for escaping through the roof. Exhaust cannot escape an attic without cool, lower-pressure air entering the attic, air known as intake. Exhaust and intake work together to keep airflow steady and create a well-ventilated attic. If this circulatory system isn’t adequate, your roof could experience a number of problems. Attic Ventilation: Telltale Signs You Need More Ice dams Ice buildup on a roof is known as ice damming.
