Pipes Sticking Out Of Roof

Needless to say these pipes should never be altered or adjusted unless done by a trained hvac technician.

Pipes sticking out of roof.

Heating and cooling des moines since 1997. Why would someone put an open pipe through the roof of their house. If you really can t stand the sight of these pipes sticking out of your house consider a dormant winter plant so that it does not get harmed by the furnace exhaust. Ever wonder what those pipes sticking out of the roof of houses is for.

The answer lies in modern day plumbing. All the plumbing fixtures in your home need air supplied to the drain pipes for the liquid to flow properly and the pipes poking through the roof are there to provide it. My house has a metal pipe that sticks out about 18 inches from the surface of my moderately pitched roof. I put quotations around connects because the pipes do not line up very well and sometimes even come apart from each other.

There are pipe boots installed on plumbing vent pipes that penetrate through roofs. This metal pipe connects to a pvc pipe in the loft space above my garage and then connects to another pvc pipe at my garage s utility sink washer hookup. No matter the type is a pipe boot becomes weathered or damaged a roof leak can occur. This is true whether the roof is sloped or flat but the type of pipe boot depends on the type of roof.

Those white plastic pvc pipes jutting out of your roof have little to do with your roof and a lot to do with your home s plumbing system. Every home is required to have at least one plumbing vent above the roof and most have several. Sometimes the pipes are a means of exhaust for a gas fired appliance so it can safely release the carbon monoxide gases created during the combustion process.
