Roof Ventilation – Is Your Roof Properly Vented?

<h1>Roof Ventilation – Is Your Roof Properly Vented?</h1>Author: <a title="Chris Smitts" href="http://www.articlesbase.com/authors/chris-smitts/94537.htm">Chris Smitts</a> Ventilation in an attic is a key part of taking care of any roof, as there are a number of adverse effects improper ventilation can have on a roof. Roof ventilation can be accomplished in a number of ways, and proper ventilation can remove excess moisture from the air and disperse extra heat. An improperly ventilated attic can rapidly climb in levels of moisture and heat, and damage either personal belongings or cause structural distress to the house. In this article, we’ll take a look at some effective ways of properly ventilating your attic, as well as some adverse effects you might experience from improper ventilation. Roof ventilation, as with any type of ventilation, requires two components – intake ventilation and exhaust ventilation. Intake vents suck cool, dry air in from outside and are usually located at the eaves of the roof. Exhaust vents push out warm, moist air from the attic and are set along the ridge of the roof, or on the gables. You can calculate how much ventilation you need with a Net Free Ventilation Area, which is the total amount of ventilation you’re getting versus the amount you need for your entire house. Keep in mind that things like insect screens or other blockages can significantly decrease your house’s ventilation capacity, and vents should be maintained like any other part of the house. Improper roof ventilation can cause a wide variety of problems, some of them more significant than others. Sumps between rafters, often called deck deflection, can occur because after a period of time (usually at least several years), a plywood roof deck will deteriorate or warp as well as get spongy and walking on it can be dangerous. This happens due to one side of plywood decking needing to be able to breathe by being exposed to circulating air. The adhesives in the plywood may deteriorate or dry rot can come about due to condensation. The best thing you can do to make sure your roof ventilation is adequate is to measure your Net Free Ventilation Area and to get information from either your landlord or real estate agent regarding the suggested Net Free Vent Area. If the numbers are at least close, you will probably avoid any ventilation related problems, but as we’ve shown, inadequate ventilation can cause numerous problems. The key to proper ventilation is making sure you have the right number of vents, and that they are all working properly.
