Root intrusion, roots in your sewer line, can cause all sorts of problems. When tree roots invade your sewer line, they have the capacity to grow long and wide and can cause some serious damage.
The roots invade your sewer line by traveling a long distance and penetrating a small hole in the pipe. This could be through a joint that has worked loose over the years.
Tree roots are the source of severe clogs for homeowners. The tiny roots are drawn to the sewer line because it is filled with water and nutrients. Once they grow big enough, they block the sewer pipe and can cause the drains in your house to backup. Sometimes the sewage can flood your basement and cause serious property damage.
