A tree inspection is a professional assessment of a tree’s health, structure and safety – usually carried out before a permit application, ahead of a property sale, after storm damage, or simply because a tree is showing signs something might be wrong. Regular inspection catches problems early, before they become a safety risk or a much bigger job.
What a Tree Inspection Covers
A proper inspection looks at the whole tree, not just what’s visible from the ground:
- Visual assessment – canopy health, leaf colour and density, deadwood, cracks, cavities and signs of decay.
- Structural assessment – lean, root plate movement, included bark and weak branch unions that could fail.
- Root collar and soil – signs of root damage, soil compaction, or root issues affecting stability.
- Advanced diagnostics where needed – tools like resistograph testing (measuring internal wood density to detect decay) or sonic tomography (mapping internal decay using sound waves) for a closer look when a visual inspection isn’t conclusive.
Signs a Tree May Need Inspection
- Leaning that’s new or has worsened
- Cracked, peeling or damaged bark
- Dead or dying branches in the canopy
- Visible fungal growth or signs of decay at the base or trunk
- Sudden changes in leaf colour, size or density
Why Get a Tree Inspection?
Beyond safety, a documented inspection is often what’s needed for council permit applications, insurance purposes, or due diligence before buying or developing a property. A written arborist report gives you evidence-based findings and recommendations, not just a verbal opinion.
Frequently Asked Questions
How often should a tree be inspected?
At least once a year for most established trees, with more frequent checks for large, aging or high-risk trees, or after severe weather.
What qualifications should a tree inspector have?
Look for certification from a recognised arboriculture body, hands-on tree care experience, and solid knowledge of local species and common disease and decay patterns.
What happens if a tree is found to be unsafe?
A qualified arborist will recommend the appropriate next step – which might be pruning, cabling, pest or disease treatment, or removal if the risk can’t be managed another way.
