Large Cedar Near Foundation: Root Risk vs. Windthrow Hazard

A large cedar ~1 meter from a house foundation, leaning away, raises foundation damage concerns.

Root-Foundation Interaction

Cedar roots are fibrous, non-aggressive. They do not crack intact foundations. Roots only exploit existing cracks if moisture is present (seeking water). Normal conditions: no root damage.

Real Risk: Windthrow

If a storm uproots the tree, the root plate lifting can damage the foundation. A large, established tree has survived many storms—but past performance ≠ future guarantee.

Assessment Limitations

Without seeing the tree, lean angle, soil, and foundation condition, a definitive recommendation is impossible. Key factors:

• Lean direction and magnitude
• Soil type and drainage
• Foundation depth and condition
• Target exposure if tree fails

Consult a certified arborist for site-specific evaluation. Proactive removal may be warranted if lean is recent or increasing.
