What Are Pipes Jacks?

Pipe jacks go around the pipes were pipes penetrate your roof. Pipes have to come up through your roof to service the house below. Every drain in your house has a pipe that penetrates your roof.

The pipes themselves are designed to allow heat and moisture to escape from inside the building, protecting its structure from water damage and other issues caused by trapped air and vapors. The purpose of these components is to provide an opening for air and moisture to escape while keeping out rain, snow, and other elements.

How Often Do Pipes Jacks Need To Be Replaced?

The answer depends on several factors, including the age of your home, the type of pipes jacks used, and the amount of wear-and-tear they have been exposed to over time. Generally speaking, it is recommended that you replace your pipes jacks every 10 years—or sooner if any signs of damage or corrosion appear. It is also important to check your pipes jacks regularly for any signs of deterioration or leakage. If you find any such problems, it is important to have them addressed as soon as possible in order to prevent further damage to your home's structure.
