Do you know how healthy your trees really are? You can observe a number of changes in your tree’s health simply by glancing out your window every day or walking past the tree as you take your dog on a stroll. But there’s often more going on beneath the surface than you can see. That’s why it’s beneficial to have your trees assessed by a certified arborist. But how often, exactly, should your trees be inspected? Great question! Keep reading to find out.

Tree Talk Takeaways

  • Homeowners should schedule a tree inspection:
    • When buying a new home
    • BEFORE a major renovation
    • When noticing signs of distress (leaning, dead branches, peeling bark)
    • Following a severe storm or preparing for an upcoming storm season
  • They should also have their trees inspected on a regular basis, at least once a year.

What Is a Tree Inspection?

A tree inspection, also known as a tree risk assessment, is a professional evaluation of a tree’s health, structural integrity, and overall safety. Arborists certified by the International Society of Arboriculture conduct these inspections to identify potential risks, such as diseases, pest infestations, dead branches, root instability, and other structural weaknesses. They pinpoint these problems by meticulously examining every inch of the tree, from its root system and trunk to its branches and leaves.

Based on the results of the inspection, the professional will make recommendations for future tree care. This may include pruning, treatments for pests or diseases, or deep root fertilization. All of these solutions are recommended in an effort to extend the tree’s lifespan and minimize the chances of an accident. In the event that tree removal is absolutely necessary, the certified arborist can complete the job before the tree has a chance to come tumbling down on your home, garage, or car.

How Often Should Your Residential Trees Be Inspected?

As a general rule, large or newly planted trees should be inspected at least once a year. This allows a certified arborist the chance to catch potential issues early and provide necessary care before minor problems turn into major concerns. The tree risk assessment (TRA) is especially important for older trees, which are more susceptible to decay and structural weaknesses, and trees that have a history of disease or past storm damage.

Make sure you can enjoy your trees for many years to come by scheduling an inspection with the certified arborists at Heartwood Tree Care. We will help you determine whether your trees need a Level 1, Level 2, or Level 3 tree risk assessment:

  • A Level 1 tree risk assessment is a basic visual inspection to identify any immediate, visible signs of decline, structural issues, or potential hazards.
  • A Level 2 tree risk assessment provides a more detailed 360-degree evaluation. This level of assessment usually comes with a cost, as it takes more time and expertise to perform thoroughly.
  • A Level 3 tree risk assessment is the most advanced and is only recommended when a certified arborist suspects internal decay or issues that are not visible from the outside. This assessment involves using a resistograph — a specialized tool with a fine needle that is inserted into each root flare of the tree. The resistograph measures resistance as it drills into the wood, allowing the arborist to detect internal decay and evaluate how extensive it is in the specific area being tested. Because this method is invasive, it’s only used when multiple symptoms suggest that a deeper look is necessary.

By choosing the appropriate level of assessment, our certified arborists ensure your trees are accurately evaluated and cared for.

Situations When Tree Inspections Are Especially Important

While regular inspections are always a good idea, there are certain situations when requesting an assessment outside of your normal schedule is vital. For example, if you’re getting ready to buy a new house or complete renovations, have noticed a change in your tree’s appearance, or have just endured a severe storm, it’s recommended you call your local arborists right away.

Buying a New Home

If you’re purchasing a new home, don’t just focus on the house itself — pay attention to the trees on the property as well. Large trees can add value and curb appeal, but they can also pose a risk if they are unhealthy or structurally compromised. A tree inspection before buying a home can help you understand any potential risks and what maintenance might be required. We’ve had clients buy houses without inspections that ended up with the unexpected expense that could have been brought up before closing. 

Renovating Your Existing Home

Planning a home renovation? If your project involves major landscaping, new additions, or excavation, you should have your trees inspected beforehand. Construction work can impact root systems and put stress on trees, potentially weakening them over time. A certified arborist can advise you on how to protect your trees during the renovation process.

When You Notice an Issue

If you see something unusual — such as discolored leaves, falling branches, peeling bark (species specific), or other signs of decay — it’s time to schedule a tree inspection. Many tree issues start small but can escalate quickly if left unaddressed. And before you know it, you’re dealing with a tree that has large clusters of dead branches or is leaning precariously. Make sure to have any changes in your tree’s appearance evaluated by a professional to reduce the chances of potential injury and property damage.

After a Severe Storm

Heavy rain, strong winds, and even the occasional snowstorm can take a toll on your trees. A post-storm inspection can help determine if any trees on your property need stabilization, pruning, or removal to prevent future risks.

Do Newly Planted Trees Need to Be Inspected?

Have you just recently planted a tree in your yard? To make sure it grows healthy and strong, don’t neglect routine inspections. Young trees are particularly vulnerable in their early years as they adjust to their environment, develop strong root systems, and adapt to soil conditions. A certified arborist can assess whether the tree is receiving enough water, whether the soil conditions are suitable, and if there are any signs of pests or disease.
