All About Roof Vents

Keeping your roof up is not something that is easy to do. However, we have made it easier for you by providing you with the best information online about roofing repairs, and renovation. We are your best online roofing resource. The following article will explain roof vents, so that you can get a better understanding.

Ventilation is critical when it comes to attics. Ventilation is needed as moisture is gathering due to human activity. Inside a building this is not very harmful as most of the year the inside of a house is warmer than the outside and almost all the moisture is retained in the air. In attics though the situation is different as the conditions change more dramatically as seasons pass. This is where roof vents come through to save the day.

Roof vents come in a wide variety of shapes and technologies all of them suited for different purposes. Static vents are those roof vents that do not have any mobile part. Practically they are just some glorified holes in the roof. As moisture tends to rise up it is best that they are situated on the very top of the roof. Also they should be given the appropriate kind of flashing otherwise you might get a radically different type of moisture when it is raining.

Power ventilators are a more advanced type of roof vents. In principle they use the a turbine to catch the wind which in turn will help the air from the attic being sucked out. All sounds reasonably fine, but as with all alternative sources for energy, you must take into account that the wind will occasionally stop mostly during summer when the heat will all but melt you You get the picture.

The fan driven ventilators use electricity to drive out the old air from the attic. Reliable, expensive and an additional item on your electricity bill.

Altogether I still recommend the static vents. The best subtype available are I think the ridge vents. They are located on the very top of the roof along the ridge, hence the name.

Typically government regulations will take into account the amount of ventilation needed during winter, but let's be honest humidity may be nuisance but it is nothing compared with the summer heat. Typically for the later you will need better roof vents.

When estimating the ventilation needs you must know the volume of air that your attic holds. This is not as complicated as it sounds. First you need to measure the area of the attic. If your house has a non regular, weird shape divide the surface into rectangles and measure the width and length for each one of them. For every rectangle you have multiply the width with the length then add up all the numbers and voila you have the area. Next you need to measure the height of the attic, this is a pretty straightforward task and it won't need any hard calculations. Now to find out what volume your attic has multiply the area with the height and then divide the number with four.
