Tree Risk Assessment

Not all trees appearing to have a problem are at risk. Likewise, all trees are not necessarily safe if problems are not apparent. To clear up possible confusion, we at Arbortec Tree Service offer tree risk assessments to our customers in the Denver area.

Some tree and shrub problems begin as seemingly minor issues, something the average property owner would assume is nothing to worry about. While a broken main limb or unstable roots are obvious, a woody powder dusting the bark or discolored leaves hanging on a few branches are also indicators that the tree could be in jeopardy.

Hidden Signs of Danger


If there is a question in your mind about a possible hazard in your landscape, it’s best to call a certified, tree service Denver Arborist to check it out. Too often, what begins as a small issue easily addressed with simple tree care and treatment turns into a big vulnerability with a larger price tag. Here are some of the hidden signs to watch out for.

Discolorations: This can happen to leaves or needles. One branch might be affected, or the top of the tree, or the whole plant.

Broken branches or stems: Pests and diseases create weaknesses to part of the tree resulting in limb loss during winds, storms or for no apparent reason.

Protruding or invading roots: Roots that used to be below ground but now bulge above the lawn could mean the tree is swaying and leaning. If your driveway is suddenly lifting, the culprit could be a tree’s roots.

Shedding bark: Some trees shed bark as part of their natural growing process. However, patches of bark falling off the tree, particularly when accompanied by what appears to be sawdust or holes, is a sign of a pest infestation.

Failure to thrive: A tree was lush and full in the past but now seems dull and sparse could be suffering from a chemical problem or pest issue. If it used to bloom and does not now, that is also a sign of failure to thrive.

Each symptom may have multiple causes. Some require treatment, and some only need patience, waiting for the tree or shrub to outgrow the issue or the season to change. For certain species, these changes are part of the natural lifecycle. We help you determine the cause and effect, so your tree can not only survive but thrive.

Our Risk Assessment Process


Property owners worry about the unsightly appearances of their trees, or shrubs covered with webbing, or both losing leaves. Calling our Denver tree service at Arbortec is a good first step in determining what might be bugging your landscape.

We inspect the problem and ask you extensive questions about anything happening near the landscape. Use of chemicals or fertilizers, trenching or excavating, heavy equipment or changes in care and watering could all be causes of tree problems.

In some cases, the best action is taking none. Waiting for the season to pass or the plant to grow through the damaged phase may be enough.

When treatment is called for, we rely on our International Society of Arboriculture (ISA) training and continuing education to provide you with access to the latest science and research about proper tree and shrub care. Our Certified Arborists list your options, so you can make an informed decision about this investment in your Denver, CO property.
