In much of Australia, the weeks leading into summer bring a familiar pattern: hot, humid days followed by sudden, heavy storms. When a storm cell rolls over, your roof and gutters have a few minutes to move a huge amount of water away from your home. If a gutter is packed with gum leaves or a roof has a small hidden weakness, that is when the trouble starts: overflowing water, damp ceilings, stained walls and, in the worst cases, structural damage.
The good news is that October is the ideal time to get ahead of it. This guide gives you a practical, step-by-step pre-storm routine for cleaning your gutters and downpipes, checking your roof for leaks and deciding what to fix yourself and what to leave to a licensed roof plumber or roofer.
Why Early Spring Is the Time to Act
Storm season varies across the country. In the eastern states and Queensland, severe thunderstorms are common from spring through summer, and in the tropical north, the wet season brings monsoonal downpours from roughly November. Meanwhile, hotter weather also raises bushfire risk in many regions. Spring maintenance covers both.
- Winter and spring leaf drop: Gum trees shed bark, leaves and flowers throughout the year, so gutters fill faster than many people expect.
- Heavy rain tests everything at once: A gutter that copes with light drizzle can overflow in a downpour if it is partly blocked.
- Small problems grow: A tiny crack or a loose screw can turn into a real leak after the first big storm.
- Repairs are easier now: Roof plumbers and roofers get very busy after major storms. Fixing things before the season saves you waiting and stress.
Safety First: Read This Before You Climb
Falls from ladders and roofs are one of the most common causes of serious home maintenance injuries. No gutter is worth a trip to hospital. Follow these rules every time:
- Never work on a wet or windy day, and never go onto a roof in the rain. Wet metal and tiles are extremely slippery.
- Use a sturdy ladder on flat, firm ground, extended about one metre above the gutter. Use the 4-to-1 rule: for every 4 metres of height, place the base 1 metre away from the wall. Have someone hold the base, and tie off the top where possible.
- Do not overreach. Keep your belt buckle between the ladder rails and move the ladder instead of leaning sideways.
- Stay well clear of power lines and the service wires that connect to your house. Never use a metal ladder near them.
- Wear non-slip shoes, gloves and safety glasses. Gutters often contain sharp metal edges and spiders.
- Be careful with older homes. If your house was built before the early 1990s, roofing, eaves, gutters or fibre-cement sheeting may contain asbestos. Do not drill, cut, scrub or break these materials. If you suspect asbestos, stop and contact a licensed assessor or removalist.
- Know your limits. If your roof is steep, high or two storeys, hire a professional.
Step 1: Clean Your Gutters Properly
What you will need
- A stable ladder, ideally with a stand-off bracket to protect the gutter
- Strong gloves and safety glasses
- A gutter scoop or a small plastic trowel
- A bucket with a hook or handle
- A garden hose with a spray nozzle
- A torch and a small wire brush
How to do it
- Start at the downpipe end and work away, scooping leaves, twigs and sludge into the bucket instead of dropping them on the ground.
- Remove the heavy debris first, then brush out the leftover grit.
- Flush the gutter with the hose, starting from the high end and working toward the downpipe. Watch how the water flows. Standing water usually means the gutter sags or the fall (slope) is wrong.
- Check the downpipe outlet. If water drains slowly, clear the blockage by running a hose from the bottom or using a plumber's snake.
- Look at the gutter itself. Check for rust spots, cracks, loose brackets, sagging sections and failed joints.
Dispose of the debris in your green bin or compost. Dirty gutter sludge is also fine to use as mulch on garden beds in moderate amounts, as long as it is free of chemicals and weeds.
Step 2: Clear Downpipes and Stormwater Drains
Clean gutters mean nothing if the water has nowhere to go. Water leaving your downpipes is meant to travel into your stormwater system, and in many properties these pipes can clog with leaves, silt and even tree roots.
- Check that every downpipe is connected to a stormwater pit or drain and is not discharging against your foundations.
- Lift the grate on any stormwater pit near the house and remove leaves and silt.
- Test the flow by running a hose into the downpipe. If water backs up, there may be a blockage lower down.
- Make sure the ground around the house slopes away from the walls.
Note: Stormwater rules differ between councils and states. Never redirect water onto a neighbour's property. If a blocked stormwater line is underground, call a licensed plumber or drainer.
Step 3: Consider Gutter Guards, But Choose Carefully
Gutter guards reduce leaf build-up, but they do not remove the need for checks. Fine debris, seeds and gum blossom can still collect on top of or under them.
- Mesh guards: Fine mesh stops most leaves and are widely used. Make sure they are fitted properly so they do not trap water.
- Brush or foam inserts: Cheap and easy, though they can clog and degrade over time.
- Bushfire-prone areas: If you live in a bushfire-prone area, check your local fire authority and council guidance. Non-combustible guards, such as metal mesh, are generally recommended over plastic or foam, because embers can ignite dry debris in gutters.
Even with guards, inspect your gutters at least once or twice a year.
Step 4: Check Your Roof for Leaks
Many leaks are found only after water appears on the ceiling, by which point damage may already be done. A simple inspection routine can catch problems much earlier.
From the ground
Walk around your house with binoculars or a zoom camera, and look for:
- Cracked, slipped or missing roof tiles
- Rust spots or lifted sheets on metal roofs such as Colorbond or Zincalume
- Damaged or sagging ridge capping
- Loose or detached flashing around chimneys, skylights and vents
- Gaps in valley gutters
- Moss, lichen or plants growing on the roof
- Branches touching or hanging over the roof
From inside the roof cavity
If it is safe, go into the roof cavity on a bright day with a torch, wearing a dust mask, gloves, long sleeves and boots. Step only on the joists or a safe walkway, never on the plasterboard. Check for:
- Pinpoints of daylight coming through the roof, which signal gaps or holes
- Dark water stains, damp or mouldy timber and wet or compressed insulation
- Dripping or damp patches under valleys, skylights and vents
- Signs of pests, such as droppings or chewed insulation
If you find a wet patch, trace the water uphill. Water usually enters higher than where it appears and travels along rafters before dripping down.
The hose test
To track down a stubborn leak, have a helper in the roof cavity while you run a hose over small sections of the roof from the ground or a safe low position, starting at the lowest point and working upward, a section at a time. When the helper sees water, you have found the area. Never do this on a roof you cannot reach safely.
Common Leak Spots on Australian Roofs
- Valley gutters: The joins where two roof sections meet carry a lot of water and often collect debris, which makes them a frequent leak source.
- Flashing: The metal strips around chimneys, skylights, vents and walls can loosen or corrode.
- Ridge capping on tile roofs: The cement or flexible pointing that bonds ridge caps can crack and fall away over time.
- Broken or slipped tiles: Often caused by storms, falling branches or foot traffic.
- Metal roof fasteners: On Colorbond and other metal roofs, screws and washers can loosen or degrade, particularly after years of heat expansion and contraction.
- Roof penetrations: Vents, antenna mounts, solar panel fixings and plumbing stacks all create potential entry points.
- Gutter overflow: Blocked gutters can push water back under the roof edge and into the eaves.
What You Can Fix Yourself
Some small jobs are reasonable for a confident, careful DIYer on a safely accessible roof or gutter:
- Re-sealing small gutter joints: Clean and dry the area, then apply a neutral-cure roof and gutter sealant suited to your gutter material. Avoid acetic-cure bathroom silicones on metal, as they can promote corrosion.
- Tightening loose gutter brackets and screws, where you can reach them safely from a ladder.
- Replacing a single cracked tile, if the roof is low and accessible. Be extremely careful, since tiles are brittle and easy to damage.
- Cleaning moss and debris with a soft brush. Avoid high-pressure washers on tiles and older roofs, which can damage them.
When to Call a Licensed Professional
Roof work carries real risks, and some jobs legally require a licensed tradesperson. Call a licensed roof plumber, roofer or tiler if:
- The roof is steep, high, slippery or hard to access
- You find widespread rust, many broken tiles or sagging sections
- You cannot find the source of a leak
- Flashing, valleys or ridge capping need repair or replacement
- Your home is older and may contain asbestos-containing materials
- You need new gutters, downpipes or fascia, or the work involves stormwater connections
- You rent. Report the problem to your landlord or property manager in writing, since roof and gutter repairs are generally their responsibility
Ask for a licence number, proof of insurance, a written quote and a clear scope of work. Prices vary by location, roof type and access, so getting two or three quotes is sensible.
Emergency Tips During a Storm Leak
If a leak appears during or after a storm and you cannot get a tradesperson immediately, you can limit the damage safely:
- Move furniture, rugs and electronics away from the area.
- Place a bucket under the drip and a towel around it to reduce splashing.
- If water collects in a ceiling bulge, poke a small hole at the lowest point to release it into a bucket. This prevents the whole ceiling from collapsing under the weight.
- If water is near light fittings or power points, turn off the power to that area at the switchboard and call a licensed electrician.
- Take photos of the damage for your insurance claim.
- Do not climb onto the roof during or just after a storm. Wait for safe conditions or call an emergency roof plumber.
Your Pre-Storm Season Checklist
- Clean gutters and flush them with water
- Clear downpipes and stormwater pits
- Inspect gutter brackets, joints and rust
- Trim branches that overhang the roof
- Check tiles, ridge capping, metal sheets and flashing
- Inspect the roof cavity for stains, daylight and damp insulation
- Secure loose items in the yard such as outdoor furniture and trampolines
- Check your home insurance policy and its storm cover
- Save the contact details of a trusted roof plumber and electrician
Frequently Asked Questions
How often should I clean my gutters?
At least twice a year, and more often if you have overhanging gum trees. Many homeowners clean them before storm season and again after autumn leaf drop.
How much does professional gutter cleaning cost?
Prices vary widely depending on house size, height and location. Getting a few quotes is the best way to find a fair price in your area.
Can blocked gutters really damage my house?
Yes. Overflowing water can enter eaves and roof cavities, damage fascia boards, cause damp and mould and undermine foundations.
Is it safe to use a pressure washer on my roof?
It is not usually recommended. High pressure can damage tiles, strip protective coatings and force water under roofing materials.
Does home insurance cover storm damage?
Many policies cover sudden storm damage, but may not cover damage caused by poor maintenance. Check your policy wording or ask your insurer.
Final Thoughts
An hour or two of gutter and roof checks now can save you thousands in repairs later. Clear the gutters, test the downpipes, look closely for early signs of leaks and know when to call in a professional. Do the work safely, and when in doubt, keep both feet on the ground and let a licensed tradesperson handle the heights.
