Key takeaways
- Most construction damage is to roots, and it shows up years later
- Fence off the root zone before work starts
- Avoid piling soil, parking or storing materials under trees
- Prune roots cleanly if digging cannot be avoided
Where the damage happens
Roots spread far beyond the drip line, and most of the feeding roots sit in the top foot of soil. Trenching, grading, compaction and fill can all cut or smother them.
The tree may look fine for a year or two and then decline.
Plan and protect
Before work starts, mark trees to keep and set protective fencing as far from the trunk as the site allows. Keep heavy equipment, soil and materials outside the fence.
Talk to the builder about utility routes so trenches do not cut through the root zone.
When roots must be cut
Pruning roots cleanly at a planned distance with a trencher or air tool is much better than a ragged cut by a machine. Follow it with watering, mulch and a check on the tree.
An arborist can review the plans and mark the best path.

Quick answers
How far from the trunk should fencing go?
As far as practical. A common guide is about a foot of distance for each inch of trunk diameter.
Can I add soil over roots?
Adding more than a few inches can suffocate roots.
