Reviews from Our Customers

A tree risk assessment looks at the potential for a tree or branch to fail and considers what could be affected if that happened. Rather than focusing only on a tree’s appearance or health, this type of evaluation weighs observed conditions against the surrounding site — nearby structures, pedestrian areas, driveways, and how the space is used. As part of our full range of tree services in Westminster, we evaluate these factors together to help property owners understand their options.

Tree risk can’t be reduced to zero, and no assessment can predict exactly when or whether a tree or branch will fail. This page explains what a tree risk assessment generally involves, what may be considered, and what property owners can expect afterward.

When to Consider a Tree Risk Assessment

Property owners often consider a tree risk assessment after noticing a change in a tree’s condition, following a storm, or before a change in how an area is used — such as adding a patio, playset, or parking area near a mature tree. A broader tree inspection may also identify observable conditions that lead to a more focused risk evaluation. If you’re unsure whether your situation calls for one, see when a tree risk assessment may be worth scheduling.

Concerns about a tree’s vigor, disease symptoms, or environmental stress are typically better addressed with a tree health assessment, since risk evaluation and health evaluation look at different — though sometimes related — questions.

Observable Conditions That May Warrant Evaluation

Certain visible conditions are often part of what’s considered during a tree risk assessment, including a leaning trunk, cracked or broken branches, dead branches, trunk defects, cavities, and visible root concerns or root-zone changes near the base. On their own, none of these features automatically means a tree or branch is likely to fail — they’re weighed together with the rest of the picture.

Below, we cover how the tree, site, and nearby targets relate to risk, what’s generally considered during an evaluation, and how the use of the surrounding area factors in.

Tree, Site & Potential Targets

Tree risk generally reflects the relationship between a tree’s structural condition and what’s nearby — sometimes called potential targets, such as a house, driveway, fence, or an area where people regularly walk or park. A structural defect near an unused corner of a yard carries a different practical consideration than a similar defect over a walkway or parking area, which is part of what makes a tree a potential risk to property.

Factors Considered When Evaluating Risk

Evaluating potential tree or branch failure generally involves looking at the tree’s structure and defects, site conditions like soil and root-zone changes, tree stability, and recent events such as storms or nearby construction. We also consider the likelihood of failure, what could be affected, and the possible consequences together, rather than any single factor in isolation.

How Area Use & Occupancy Matter

How frequently an area is used matters as much as what’s there. A tree overhanging a rarely used side yard presents a different practical picture than one over a driveway, patio, or play area used daily. This is part of why a risk assessment considers occupancy and use alongside the tree’s physical condition.

What to Expect & Possible Next Steps

During a tree risk assessment, we look at the tree, its immediate site, and what’s nearby, then discuss what we observed and what it may mean for your property. An assessment can’t guarantee a tree’s stability or predict exactly when or whether a failure might occur — tree-related risk generally can’t be reduced to zero, and conditions can change over time, which is why reassessment sometimes makes sense after a major storm or other significant change.

Depending on what’s found, possible risk-management options can include continued monitoring, tree pruning to address specific branches, restricting or changing how an area is used, cabling or bracing in some situations, further evaluation, or in some cases, tree removal where warranted. A risk assessment does not automatically mean a tree must be removed, and no single option eliminates all risk.

A tree risk assessment is different from a tree inspection or a tree health assessment. This page focuses specifically on the potential for tree or branch failure and its relationship to nearby targets, rather than a broader visual inspection or an evaluation centered on the tree’s overall vigor and health.

Cost factors: the scope and cost of a tree risk assessment depends on variables such as tree size, accessibility, the complexity of the conditions observed, and whether further evaluation or follow-up monitoring is involved. Because every tree and property is different, we provide an estimate after discussing the situation rather than quoting a flat rate in advance.

Westminster, CO Considerations for Tree Risk

Colorado’s Front Range, including Westminster, sees swings between high wind events, heavy wet spring snow, and hail — conditions that can stress trees and sometimes reveal or worsen existing structural weaknesses. Mature trees with age-related defects or storm-damaged trees are often the ones property owners have evaluated after a significant weather event.

Arborists trained in tree risk assessment can pursue a credential from the International Society of Arboriculture (ISA) called the Tree Risk Assessment Qualification, or TRAQ; the Colorado State University Extension resource on tree growth and decay discusses this qualification and other background on how arborists evaluate tree condition. If you have a tree you’d like evaluated on your Westminster property, an on-site look is the most reliable way to understand the specific situation.

Frequently Asked Questions About Tree Health Assessments in Westminster, CO

What signs may indicate that a tree should have its health evaluated?

Signs that may justify having a tree’s health evaluated include leaf discoloration, premature leaf drop, a thinning canopy, dead or damaged branches, unusual bark changes, reduced growth, or visible root problems. These changes can have multiple possible causes, so an on-site evaluation is the most reliable way to understand what’s happening with a specific tree.

What is considered during a tree health assessment?

A tree health assessment generally looks at the canopy, branches, trunk, bark, and visible roots, along with surrounding soil and site conditions. We also consider factors like sun exposure, drainage, nearby construction or grading, and the tree’s history, since environmental context plays an important role in understanding its condition.

Can yellow leaves or a thinning canopy mean a tree is unhealthy?

Yellow leaves or a thinning canopy can be associated with an unhealthy tree, but these symptoms alone don’t confirm a specific cause. Environmental stress, seasonal changes, insects, disease, and site conditions can all produce similar visible signs, which is why a broader evaluation is useful before drawing conclusions.

Can insects or disease cause tree decline?

Yes, insects and disease can contribute to tree decline, but so can environmental stress such as drought, soil compaction, or root damage. A stressed tree is often more susceptible to pests and disease, and it isn’t always possible to identify the underlying cause from a single symptom without a closer evaluation.

Does an unhealthy-looking tree always need to be removed?

No. An unhealthy-looking tree doesn’t automatically need to be removed. Depending on what an assessment finds, next steps might include monitoring, adjustments to site conditions, pruning to address damaged branches, or in some cases, further discussion about removal. The right response depends on the specific tree and situation.

What information about the tree or property is helpful during an assessment?

Details like when symptoms were first noticed, recent construction or grading, changes in watering, and the tree’s general history are all helpful during an assessment. This information helps build a more complete picture, since a tree’s environment and past care often play a role in its current condition.
