Roof Ventilation Tips

Sunday, October 5th, 2014

images (6)Based on the kind of roof on your building or home, there are a wide range of roof ventilation systems used in construction today by companies. The information about this kind of ventilation can be frustrating for non-experts, and it can be very easy to become disappointed or puzzled about the whole thing. When and where you should use ventilation, what kind is best for your roof, and even the reasoning behind ventilation may escape you. So let’s take a little time to talk about roof ventilation and how it is applicable to different kinds of buildings.

Why is Ventilation Important?

The concept behind roof ventilation is basically control of temperature. In a cool environment, it helps to avoid ice dams by maintaining a cool roof temperature and also allows moisture to evade from areas through the attic. On the other hand, in hot environments, appropriate ventilation allows for solar-heated hot air from the basement to escape thereby decreasing a building’s cooling load and restricting stress on air-conditioning systems. Roof ventilation can even provide both roles in areas where environments range from hot to cold.

Types of Roof Ventilation

Depending on the building requirements of your area, you’ll likely need one sq. ft. of vent area for every 150 sq ft of attic space. Ventilation prevails not only for air to escape, but also for air to get into. There are several kinds of ventilation, which we will talk about now. Box ports are also known as low profile vents, flat vents, louvers or even turtle vents. They are called as static vents because they have no moving areas. Wind turbines are sometimes known as whirlybirds, and while they include moving components, they do not function a motor and instead depend on wind to power activity. These kinds of ventilation techniques move more air than conventional box vents offering there is wind flowing.
