When Should You Call a Tree Surgeon? Warning Signs You Shouldn't Ignore

Your Trees Are Telling You Something

Most people don't think about their trees until something goes wrong. A branch comes down in a storm, a tree starts leaning toward the house, or a neighbour mentions the overhanging limbs are getting out of
hand. By that point, the situation has usually moved from manageable to urgent.

The good news is that trees give off warning signs well before things get dangerous. Knowing what to look for means you can act early, which is almost always cheaper, safer, and better for the tree itself.

Deadwood and Dead Branches

Dead branches don't just look untidy. They're unpredictable. Unlike living wood, deadwood doesn't bend in high winds — it snaps. A dead limb over a roof, a car, or a garden where children play is a genuine hazard, even in mild weather.

If you spot branches that have lost their bark, aren't producing leaves in spring, or feel hollow when tapped, get them looked at. Selective deadwooding is a routine job for a qualified tree surgeon and
makes the rest of the tree safer and healthier.

Unusual Leaning

Some trees grow at a natural angle — that's not automatically a problem. What you're watching for is a change in lean. If a tree that previously stood upright has started to tilt, especially after wet weather, it could mean root instability or soil movement beneath the surface.

Exposed or lifted roots on one side of the base are another tell. This is a situation that warrants a professional assessment rather than a wait-and-see approach.

Cracks, Cavities and Fungal Growth

Deep vertical cracks in the trunk, large cavities, or bracket fungi growing at the base of a tree are all signs of structural weakness or decay inside the wood. Fungal brackets in particular indicate that rot is
already underway — what looks solid on the outside may not be.

A professional arboricultural assessment can determine how advanced the decay is and whether the tree
can be retained safely or needs to be removed.

Overgrown or Unbalanced Canopy

Trees with a heavily one-sided canopy put uneven stress on their root system, which increases the risk of failure in high winds. Dense canopies also block light and restrict airflow, creating conditions where
disease spreads more easily.

Crown thinning and reshaping isn't just about aesthetics — it genuinely reduces the load the tree is
carrying and extends its lifespan. For trees near buildings, roads, or boundary lines, regular crown
management is practical rather than optional.

Trees Near Structures or Utility Lines

Roots are opportunistic. They follow water and nutrients wherever they lead, which can mean drains,
foundations, and patios. If you've noticed cracking in paving near a large tree, slow drainage, or root
entry into inspection chambers, it's worth getting a professional opinion before the remedial work
becomes significant.

Similarly, trees growing close to overhead cables or outbuildings benefit from regular monitoring. What's a minor trim now can become a serious job if left for several years.

After a Storm

Storm damage doesn't always look dramatic. A branch that's partially split — what arborists call a 'hungup' limb — can appear stable while being under significant tension. These are best handled by someone with the right training and equipment rather than attempted as a DIY job.

Even if a storm hasn't visibly damaged your trees, high winds can stress root systems and loosen trees in the ground. A post-storm check is worth doing on any large tree close to the house or garden
boundaries.

If you're seeing any of these signs on your property, an assessment from a qualified tree surgeon will tell you exactly where you stand — and what, if anything, needs to be done.
