Is Roof Ventilation Important?

​

You will for sure experience raised energy costs, damaged roof system components and ice dams when moisture and heat will get trapped. As a matter of fact, your personal and structural items that are the inside of the attic and can reach easily the temperature of 150 degrees F will experience the same thing. There is a good chance that the condensation that you find in the attic is caused by tumble driers, washing machines, showers, dishwashers and bathtubs. Not unless of course these kinds of items like roof air extractor are being ventilation through your roof properly. 

What you will be able to see below are some of the problems that you will be able to encounter when your roof is not properly ventilated.

 

One thing that can happen is for sumps between rafters since deterioration or warping can happen on a plywood roof deck. And what is bound to happen is that it will turn spongy and not safe for you to walk on. The reason why this happens is because of the fact that one side of the plywood decking has to "breathe" through exposure to air that is circulating. Dry rot is possible and the adhesives used in the plywood will most likely deteriorate as well.

In the time of today you will soon be able to discover that there are actually a lot of kinds of attic vents that you can choose from. Some of these are: cupola vents, static vents, starter vents, power vents, gable vents, ridge vents, cornice vents/soffit and turbine vents. The shapes, sizes and styles are also in a wide range of choices such as Industrial whirlybird. There are some choices that will give you better roof ventilation but it would depend on climate, roof configuration and attic size.

There are two kinds of roof ventilation that you will be in need of when it comes to proper ventilation of the attic. The exhaust vents which are found on or near the roof's ridge line and will allow the air to get outside of the attic. The second one is the vents intake which is found at the downslope of the edge of your roof and will let in fresh air into the attic. When you will avail of roof ventilation you have to keep in mind that the insulation of your attic is not blocking the vents intake. However, if this is the case then make use of the baffles so that the insulation will be kept back from this.
