Now that you are a bit more familiar with the roof pipes and systems, let’s discuss what to do if you have a leak from those pipes and how to stop the leak.

Other Helpful Information To Know About A Plumbing Vent Pipe Leak

Unfortunately, the flashing designed for your plumbing vent pipe is typically one of the first things to leak on a roof. With that in mind, let’s focus on some helpful tips to resolve any potential leaks from the plumbing vent on your roof.

  1. Whenever there is a pipe sticking up from your roof, there is also a specifically designed type of flashing for that pipe.
  2. Your shingle might be a 25 year or 50 year shingle but few pipe flashings are actually designed for that length of time.
  3. Most builders install a pipe flashing that lasts approximately 7 years.

How the Plumbing Vent Works

The plumbing vent pipe you see in your roof is attached to all the sinks, toilets and water sources in your home, which ultimately drain into the sewer. There are two main reasons for these plumbing vent pipes.

  1. To help the water drain out of your house, just like the tiny hole in your coffee lid functions.
  2. Prevent sewer gases from entering back into the house.
