Can bored piers be affected by nearby tree roots?

Yes, potentially — significant tree roots can complicate drilling at a specific pier location, sometimes requiring pier position adjustment or additional care during installation to work around genuine root systems.

Beyond installation itself, ongoing tree root growth near piers is a genuine long-term consideration your engineer accounts for in the design, particularly for reactive soil sites where root-related moisture changes matter.

If significant trees are near your planned pier locations, flagging this during site assessment helps your engineer and contractor plan around it properly, rather than discovering root conflicts once drilling begins.
