Every roof has several vents coming out of it. They fulfill a necessary function in your plumbing system by allowing sewer gases to escape from your home. Liquids will not go down pipes unless they are followed by air. Vented pipes prevent the liquid from sucking the air from the traps on the plumbing fixtures, and therefore preventing odors from being dispersed around your home.
