Every year, Aussie homes get smashed by storms. And more often than not, trees are to blame. We’re talking snapped limbs through roofs, fallen trunks across driveways, and branches tangled in powerlines.
But here’s the thing — a lot of that damage could’ve been avoided with a bit of smart prep.
Trimming your trees before storm season hits can make the difference between a clean yard and a major insurance claim. We’ve consulted experts from Fortitude Tree and Fence and Central Coast Tree Removal Pros, and we’ll break down exactly why it matters, how it works, and what to look out for.
Core Concept: Why Trimming Helps During Storms
When a big wind hits, your tree’s root system has one job – keep the whole thing upright.
Now, most healthy trees can stand their ground in bad weather. But when the canopy is overloaded with leaves and limbs, it’s like turning your tree into a giant sail. The wind pushes harder, the pressure builds, and eventually, something gives – usually the roots or the trunk.
By reducing the foliage by around 30%, you take a massive amount of surface area out of the equation. That means less force from the wind, and less chance your tree ends up sideways on your roof.
It’s not about hacking it back — it’s about thinning it out strategically so air flows through, not against it.
Also worth knowing: tree roots do two key jobs – they feed the tree and they anchor it. In heavy rain, the soil around those roots loosens. When that happens, even solid trees can come down if they’ve got too much top weight.
So yeah, trimming isn’t just about neatness. It’s about physics and keeping your property safe.
Top Reasons to Trim Trees Before Storm Season
1. Removes Dead or Weak Branches
Dead branches are usually the first things to go flying in a storm. And even small ones can do serious damage if they crash through a window or land on a car.
If you’ve got limbs that crack when you touch them, or hang low and lifeless, they’re not going to hold up in a 60km/h wind gust. Get them trimmed off before nature does it for you.
2. Reduces Wind Resistance
A thick canopy might look lush, but it turns your tree into a wind catcher. Thinning it out — especially near the top — helps reduce drag so the wind passes through instead of pushing hard against it.
This massively reduces the chances of the whole tree leaning or tipping.
3. Prevents Overhanging Branches From Smashing Your Roof
Branches hanging over your house are risky. During a storm, they can snap and land right through your roof. Even if they don’t, leaves and twigs will clog your gutters, which can lead to water overflow and damage inside the house.
It’s simple — no overhanging branches, no smashed tiles or blocked downpipes.
4. Protects Powerlines and Backyard Structures
Trimming trees away from powerlines is a no-brainer. It helps prevent blackouts, fire hazards, and emergency callouts.
It also keeps your fence, shed, trampoline, and play equipment safe. One big limb in the wrong place can destroy thousands of dollars’ worth of stuff.
5. Keeps Trees Healthier and More Balanced
Proper trimming does more than storm-proof your tree — it actually helps it grow stronger.
By removing dead weight, you give the tree more energy to put into healthy branches. It also helps air and light move through the canopy, reducing the risk of pests and disease.
Win-win.
DIY vs Professional Tree Trimming
If you’ve got a small tree or a few low-hanging branches, you might be able to handle it yourself with a handsaw or pole pruner.
But if we’re talking big trees, close to buildings, or anything near powerlines, don’t risk it. It’s not worth falling off a ladder or causing more damage.
A qualified arborist knows how to trim the right way, without weakening the tree or leaving it off-balance. They also have the right tools, safety gear, and insurance in case something goes wrong.
Signs Your Tree Might Be a Storm Risk
Keep an eye out for these warning signs:
- Dead or cracked branches
- Mushrooms or fungi growing at the base
- Large lean or sudden tilt
- Bark peeling or splitting
- Branches touching powerlines or overhanging your roof
If you spot any of these, it’s a good idea to get an expert in to take a look – sooner rather than later.
FAQs
How much does it cost to trim a tree before storm season?
It depends on size and access. Small trims can cost $150–$300, while large or risky trees might cost $500–$2,000+. Best to get a few quotes to compare.
Can tree trimming really stop a tree from falling in a storm?
It helps a lot. No guarantee, but thinning the canopy reduces wind force and helps the tree stay stable, especially in soggy soil.
Do I need council approval to trim a tree?
Usually not for basic trimming. But if you’re dealing with a protected tree or native species, or planning a big prune, it’s worth checking your local rules. GoTreeQuotes can help with that.
Is storm damage from trees covered by insurance?
Yes, if the tree was healthy and the damage was sudden. But if the insurer thinks you ignored signs the tree was unsafe, they could knock back the claim. Regular trimming helps protect your home and your insurance.
What’s the difference between trimming and lopping?
Trimming is targeted, professional, and helps the tree long-term. Lopping is usually rough cutting without care for the tree’s health. Stick with an arborist who trims, not someone offering a quick hack job.
