What Trees Cause The Most Damage To Sewer Pipes?


Trees and plants are excellent additions to your home’s exterior. However, some greenery can affect your underground pipes. Keep reading to learn which trees cause the most damage to sewer pipes for more information!

Trees With Invasive Roots

Whether you’re planning a lawn renovation or live near foliage, it’s important to assess trees in your area. Trees that require lots of water will extend their roots to find nutrition. They can infiltrate your sewer pipes through small cracks and holes in the pipelines to secure water. The roots will affect your sewer system and cause frequent clogs and blockages.

To prevent tree root intrusion, refrain from planting these tree species in your yard:

  • Aspen
  • Maple
  • Willow
  • Birch
  • Oak
  • Beech
  • Lombardy
  • Elm
  • Fig

Non-Threatening Tree Species

Although certain trees increase your chance of root intrusion, you can still incorporate greenery in your yard. Homeowners can plant non-threatening tree species without fear of underground pipe damage. The options include cherry, dogwood, cypress, cedar, water ash, and magnolia trees. For unmentioned trees, you can speak with a landscaper to receive an estimate of expected root length.

Tree Root Intrusion Signs

Depending on the severity of the damage, root intrusion signs range from minor cracks to crushed pipes. Typically, homeowners notice frequent and unexplained clogs in sinks, toilets, and tubs. Furthermore, gurgling sounds from drains or slow water drainage are other indicators of root intrusion. When roots block pipes, waste and water can’t enter a main sewer line. If left untreated, pipelines and sewer systems can undergo damage.

Signs of Major Damage

Large cracks and crushed pipes are signs of major damage. Since underground pipelines aren’t visible to homeowners, it’s essential to recognize problems. Here are signs of pipeline cracks:

  • Sudden decline in water pressure.
  • Moist, green patches around your yard.
  • Bad odor in your basement or yard.
  • Whistling or abnormal sounds from your pipes.
  • Increased water bill (without excessive water use).
