Tree Inspection
A documented visual assessment of a tree's condition and what it means for next steps.
What happens during a professional tree inspection?
A tree inspection is mostly a slow, methodical look — at the trunk, the canopy, and the ground around the base — followed by a written record of what was seen and what it means. Here is what a typical visit involves, so you know what to expect before one is scheduled.
Request an inspectionIt is an assessment, not a treatment
A tree inspection does not do anything to the tree. Nothing is pruned, treated, or removed during the visit itself — the entire purpose is to look carefully, record what is found, and turn that into a specific recommendation. That distinction matters because it shapes what you should expect to see: an inspector spending time standing still, walking around the tree from different angles, and taking notes or photographs, rather than climbing, cutting, or applying anything. This is also why it is worth being clear about what "certified" means before an inspection is scheduled. Arborist credentials, where they exist, are issued to an individual person for a period of time, not to a company permanently — levels and scopes vary by certifying body. If a certification is relevant to why you need the inspection, ask the specific person doing the work about their current qualifications and verify the status yourself rather than taking a company's general claim at face value. The rest of this page walks through the visit in the order it typically happens: the survey itself, what specifically gets checked, how those observations turn into a recommendation, and what documentation you should come away with.
The visit, in the order it usually happens
- A visual survey from ground level, walking the treeThe inspection typically starts with the inspector walking around the entire tree rather than looking from one spot, checking the trunk, canopy, and base from several angles. Ground-level visual assessment is the foundation of most inspections — it is what catches the majority of visible defects before anyone decides whether closer or more technical evaluation is warranted.
- The trunk gets checked for cracks, cavities, and leanAlong the trunk, an inspector is looking for vertical cracks, included bark where two limbs meet at a tight angle, cavities or hollow sections, old wounds that never closed over properly, and any lean — particularly a lean that looks recent rather than a tree that has simply always grown that way. Each of these can mean something different depending on species, tree age, and what else is present, which is why they are recorded individually rather than summarized as "looks fine" or "looks bad."
- The canopy gets read for density and dieback patternFrom the ground, the inspector looks up through the canopy for thinning, dead branches, and the pattern of any dieback — whether it is scattered through the crown, concentrated on one side, or starting from the top down. The pattern often points toward a cause (root stress, a vascular problem, storm damage on one side) well before the whole tree shows visible decline, which is part of why canopy condition gets its own careful look rather than a glance.
- The base and root flare get examined for what they can show from above groundAt the base, the inspector checks the root flare — where the trunk widens into the roots — for exposure, girdling roots wrapping around the trunk, soil mounding or heaving, and any fungal growth (conks or mushrooms) at or near the base, which can indicate internal decay. Recent grading, trenching, or construction near the root zone gets noted too, since disturbed roots do not always show a visible symptom right away.
- What is nearby gets factored in, not just the tree itselfThe same defect means something different depending on what is close enough to be affected if a limb or the tree failed — a structure, a driveway, a parking area, a walkway people use regularly, or power lines. This is usually assessed alongside the tree itself rather than as a separate step, because it is what turns a defect from "notable" into "a recommendation to act on."
- Findings get written down, with a recommendation attachedWhat was observed gets recorded — typically with notes and photographs — and turned into a specific recommendation: continue monitoring, prune a specific issue, pursue further evaluation with additional testing, or that removal is warranted. A verbal impression with nothing written down is not a completed inspection in the way this page describes it.
Questions people ask
Does the inspector climb the tree or use any special equipment?
Most inspections are conducted from the ground using a careful visual survey, which covers the majority of what a routine assessment needs. Whether anything further is warranted — a resistograph reading, sonic tomography, or a climbing inspection to examine the upper canopy directly — depends on what the ground-level survey finds and how conclusive it is on its own. Ask the specific provider what their assessment will include before scheduling if that matters to you.
How long does an inspection take?
It depends on a few things rather than a fixed length: the size of the tree, how much of the canopy and root zone is easily visible, whether one tree or several are being assessed, and whether the situation calls for anything beyond a standard visual survey. A single, accessible tree with a straightforward visual assessment takes less time than a large or partly obscured tree, or a multi-tree property survey.
What should I have ready before the inspector arrives?
Clear access to the base of the tree and, where possible, an unobstructed view of the canopy from a few angles helps make the visual survey more thorough. It also helps to have any relevant history ready to mention — recent construction or grading nearby, irrigation changes, storm damage, prior pruning, or anything that prompted the question in the first place. None of this is required, but it gives the inspector useful context.
Will I get something in writing?
A completed inspection should leave you with documented findings — what was checked, what was observed, and the recommendation — rather than only a verbal summary on-site. How detailed that documentation is can vary: a routine check may produce a shorter record, while an inspection for a real-estate transaction, insurance purpose, or legal matter typically needs a more formal written report. Confirm what form the documentation will take before scheduling if you need it for a specific purpose.
Does a normal-looking inspection mean the tree is guaranteed safe?
No inspection can guarantee that, and a credible one will not claim to. A visual assessment is limited to what can be seen — internal decay that has not yet produced an external sign can be missed by a ground-level survey alone, which is part of why further testing exists for cases where the visible evidence is inconclusive. What an inspection gives you is a documented, professional judgment based on what was actually observable at the time, dated so you have a record to compare against later.
