Causes of a Damaged or Clogged Roof Vent Pipe

There are a number of things that can cause your roof vent pipe to become damaged or clogged. Here are some of the most common causes:

Leaves and debris - If there are trees near your home, leaves and other debris can fall into your gutters, and clog the roof vent pipe.
Animal nests - Animals can build nests in your gutters, or on top of your roof. These nests can block the flow of air through the vent pipe, and cause it to become clogged.
Ice dams - In the winter, ice can build up in your gutters and on your roof. This can block the flow of air through the vent pipe, and cause the pipe to break.
Clogged vent stack - A clogged vent stack can cause the roof vent pipe to become clogged. The stack is the part of the vent pipe that extends above the roof.
