The Need For A Roof Closure Vent
It's surprising how things can be all around you and you may never know. Take a roof closure vent, for example. You may or may not have one, or know what one is, even. However, this nifty little gadget or system may be protecting you from all sorts of things - like a voided home warranty, or condensation problems where you can't see them, or birds getting into your attic.
For those who are clueless about the make-up of their roofs, there are some basic facts that are easily understood. A roof is subject to many stresses. One is extremes of temperature. Actually, painting a metal roof a light color in hot climes and a dark one in cold is the best solution to temperature. Venting has more to do with moisture.
As air from inside the house rises, it carries moisture with it. The warmer the air, the more moisture it can hold. The air gets trapped beneath the cool roofing where the moisture can condense, causing rot, mold, and corrosion. By venting the space underneath the roof, this moist air can be drawn out and replaced by fresh, drier air from outside.
The primary purpose of a vent is to let air in and out. Vents under the eaves - 'soffit vents' - allow outside air to be drawn in to replace air flowing out of vents along the ridge. The exchange is caused by wind moving across the top of the house. The process is fairly simple if the house has a straight, pitched roofline. It gets more complicated in modern homes with many gables and additions.
There is another problem. Openings in roofing are great ways for bugs, birds, small climbing rodents, and the elements (rain and snow) to get inside your attic. Therefore you need vents with screening or baffles to keep them out. Well-designed venting systems keep everything out but air.
Check out online sites that offer vents. There's a lot of information on the are importance and function of different types. Installation is easy, using adhesive strips on the units themselves. The vent may carry a warranty that last as long as the roof. There are one piece and two-piece units, or vents that are as long as the ridge itself.
There is some debate on which method works best and even whether you should vent or not. However, roofing manufacturers seem to see the benefit of venting and may not honor their warranty if it is not done. Venting, of course, is most easily performed during construction of the building. Balance is important, too. If too much air goes out and not enough air flows in, air will be drawn from the interior of the home. This, of course, increases heating and cooling costs.
So the main idea is simple. Get hot, wet air out and let cooler, dryer air in on a continuous basis. At the same time, keep creepy crawlies, flying things, and rain or snow out without interfering with the desired air flow. Fortunately for homeowners, there are products on the market designed to do both with maximum efficiency.
