Is the Tree About to Fall?

A sudden storm rolls in, and you hear a loud crack—seconds later, a tree crashes onto your fence, or worse, your roof. While this sounds dramatic, falling trees are a real risk for homeowners. Good news is that many tree failures can be predicted (and prevented) with a simple tree risk assessment. Let’s explore how to spot danger signs, when to call professionals to remove trees, and how to protect your property.

What Causes Trees to Fall?

Weather extremes like Australian storms, heavy rains, or droughts play a major role in tree failures. During intense storms, saturated soil can loosen a tree’s grip on the ground, while strong winds push it beyond its natural resistance. Even dry spells pose risks—prolonged drought dries out wood, making it brittle and prone to snapping.

Disease and pests are silent saboteurs. Termites, wood-boring insects, and fungal infections (such as root rot) slowly eat away at a tree’s structural integrity. For instance, mature eucalyptus trees are particularly vulnerable to internal decay as they age, which can go unnoticed until it’s too late.

Poor root health is another hidden danger. Shallow roots, soil erosion from heavy rains, or damage caused by nearby construction work can destabilise even trees that appear healthy above ground. Roots anchor a tree, so any compromise here raises the risk of collapse.

Lastly, age and weight matter. Older trees naturally weaken over time, while uneven growth—like a heavy limb on one side—creates imbalances. These factors make trees more likely to split or fall, especially under stress.

While you can’t control the weather, regular inspections help catch these issues early.

How to Assess Tree Risks Yourself

You don’t need to be an arborist to spot obvious red flags. Here’s a basic checklist for homeowners:

Check the trunk: Look for deep cracks, cavities, or peeling bark. Mushrooms growing at the base often signal internal rot.

Inspect the roots: Exposed, severed, or decaying roots reduce stability. Soil heaving (mounds around the base) can indicate root lift.

Examine the canopy: Dead branches, sparse leaves, or sudden leaf loss suggest poor health.

For example, a tree that leans suddenly after a storm may have root damage. Similarly, multiple dead branches in the canopy could mean disease is spreading. Finally, to keep yourself safe, avoid inspecting trees during or immediately after severe weather. Never climb a ladder or touch a tree near power lines.

Signs You Need to Call an Expert Immediately

Some risks are too dangerous to handle alone. Contact a qualified arborist if you notice:

Severe trunk damage: Vertical cracks wider than a few centimetres, or hollow sections exceeding 30% of the trunk’s diameter.

Sudden leaning: A tree that tilts abruptly, especially if soil is cracked or raised on the opposite side.

Fungal growth: Clusters of mushrooms or conks (shelf-like fungi) on the trunk or roots often indicate advanced decay.

Proximity to structures: Trees hanging over roofs, driveways, or play areas require professional evaluation, even if they appear healthy.

Arbor Co Tree Services recently assisted a Sydney homeowner who noticed a large gum tree leaning toward their shed. Our assessment revealed extensive root rot from nearby plumbing leaks—a risk the homeowner hadn’t considered.

How Much Does a Tree Risk Assessment Cost?

Most assessments in Australia range from 200 to 600, depending on:

Tree size and number: Larger trees or multiple trees take longer to inspect.

Location: Trees near buildings or power lines require more detailed checks.

Urgency: Emergency inspections after storms may cost slightly more.

For context, a single backyard tree assessment typically sits at the lower end (200–350), while a full property evaluation with a detailed report can reach $600+. At Arbor Co Tree Services, we offer upfront quotes so you know exactly what to expect.

How to Choose a Reliable Tree Removal Expert

If an assessment confirms your tree needs removal, hiring the right team is critical to ensuring safety and compliance. Start by verifying their qualifications—look for certification from reputable bodies like the Queensland Arboricultural Association (QAA) or equivalent industry standards. This guarantees they’ve met rigorous training and safety requirements. Equally important is checking for public liability insurance, which should cover at least $10 million. This protects you financially if accidents occur during the job.

Avoid “backyard operators” who lack proper tools or training. Professional tree removal isn’t just about cutting down a tree—it involves careful planning to protect your property, nearby structures, and healthy vegetation. Experienced teams use specialised equipment and techniques to minimise risks, ensuring the job is done safely and efficiently.
