Can tree roots cause water line leaks?

Absolutely, tree roots can infiltrate water lines and are a common cause of leaks. If you suspect root intrusion, it’s important to have a professional evaluate and address the issue. Oftentimes a very small water line leak can attract roots. The roots then grow around the water line seeking water and making the leak worse (or creating additional leaks). This is most common during periods of drought, when roots are working overtime to find a water source.
