What Is a Tree Risk Assessment?
Understanding the process and why it matters for your property
At Sperry Tree Care, one of the most important services we offer is Tree Risk Assessment, also known as TRAQ—a structured evaluation that helps determine whether a tree poses a risk to people, structures, or other assets.
A tree risk assessment is a formal process used by a TRAQ Qualified Arborist to identify potential hazards associated with trees. It involves evaluating the likelihood of a tree, branch, or root failure, the potential targets (such as homes, vehicles, or people), and the consequences of that failure.
In short, it answers:
- Is the tree likely to fail?
- What could it hit?
- How bad could the outcome be?
Why It Matters
Trees are valuable assets, but when they’re damaged, diseased, or structurally unsound, they can also become liabilities. A tree risk assessment helps homeowners and property managers make informed decisions about whether a tree needs pruning, removal, monitoring, or no action at all.
Here in the Pacific Northwest, where storms, wind, and saturated soils can cause unexpected tree failures, proactive assessments are key to protecting people and property.
What the Process Looks Like
When you schedule a tree risk assessment with Sperry Tree Care, a certified arborist will:
- Inspect the Tree – Looking at roots, trunk, limbs, and canopy for signs of weakness, disease, or decay.
- Assess the Site – Considering soil conditions, past weather events, and what’s around the tree.
- Evaluate Risk – Using industry-standard methods (ISA Tree Risk Assessment Qualification—TRAQ)
- Recommend Actions – Offering solutions such as pruning, cabling, or removal, based on the level of risk.
- Write a Report – To keep a record of the inspection.
When Might You Need a TRAQ?
- After a major storm
- If your tree shows signs of decay, dieback, or lean
- Before construction near trees
- As part of routine tree maintenance and safety planning
- In the event of litigation
