Non-Destructive Root Investigation by Level 5 Arborists
Our local AQF Level 5 Arborists provide non-destructive tree root investigation and mapping across The Hills Shire Council area, including Castle Hill, Kellyville, Baulkham Hills and Winston Hills.
Root investigations are commonly required where trees are located near proposed buildings, driveways, services or footings, or where development works intersect Tree Protection Zones under AS 4970 Protection of Trees on Development Sites.
When Is a Tree Root Investigation Required?
- Proposed works encroach into the TPZ or SRZ
- Driveways, slabs or footings are proposed near retained trees
- Service trenches or pier foundations are planned
- Tree roots are suspected of contributing to structural damage
- Council or a certifier requests confirmation of root presence or absence
Our investigations determine whether roots are present, their depth and diameter, and how works can proceed compliantly.

Frequently Asked Questions
Does a root investigation damage the tree?
No. Investigations are non-destructive when carried out correctly. Controlled excavation methods are used to expose roots safely.
Are root investigations accepted by Hills Shire Council?
Yes, when prepared by a Level 5 Arborist. Reports comply with AS 4970 and are suitable for DA, CDC and engineering submissions.
Can a root investigation reduce the need to remove a tree?
Yes. Confirmed root locations often allow design changes. Mapping can demonstrate works can proceed without unacceptable impacts.
When should a root investigation be done during a project?
Before finalising construction or engineering plans. Early investigation avoids redesigns, delays and unnecessary tree removal.
