The extreme weather events like storms, hailstorms and heat waves in Melbourne might cause additional strain to the roof, gutter, render and the drainage system of your building. A building inspection after any extreme weather event will help you to detect the issues that are not visible from the ground.
Why Melbourne’s Weather Pattern Is a Genuine Building Risk Factor
Climate changes are an ever-present threat to Melbourne houses. It is entirely possible that an unusually hot summer day will be succeeded by a severe storm, or long drought seasons could render moisture-sensitive soil much drier than several months ago.
The Bureau of Meteorology describes a severe thunderstorm as one that may produce large hailstones, destructive wind gusts, tornadoes or a large amount of precipitation leading to flash flooding. Such phenomena may influence rather a small area, which explains why a property may get severely damaged and yet neighboring properties would seem mostly intact.
VICSES mentions that storms may lead to property damage due to strong winds, hail, tree branches falling on houses, waterlogging and loose objects turned into projectiles. Ensuring that your downpipes are not blocked is one of the simplest measures recommended by VICSES in order to prevent property damage.
Then there is the heat.
Reactive soil types have been widely used in Melbourne to construct many houses. Droughts are likely to bring about moisture changes in the soil, which in turn cause movement in footing and cracks. However, this does not imply that all summer cracks are signs of structural issues. Changes in cracking accompanied by other signs of movement such as sticking doors and uneven floors call for serious attention.
Extreme weather is not necessarily needed for building problems to arise. Repeated exposure is key.
What to Check After a Major Storm or Hail Event
A quick walk around the property can tell you that something is wrong, but it won’t always tell you how serious the problem is.
Roofing, gutters and areas around windows can be difficult to inspect safely from ground level. Some damage only becomes obvious once water enters the building.
Roof and Exterior
After a major storm or hail event, an inspector will look for visible signs of damage to the roof and external parts of the property.
This can include:
- Dented or cracked metal roofing.
- Broken or displaced roof tiles.
- Damaged ridge capping.
- Loose or damaged flashing around roof penetrations.
- Cracked skylights or roof-mounted components.
- Gutters that have pulled away from their fixings.
- Blocked or damaged downpipes.
- Damaged external cladding or render.
- Water entry points around windows and doors.
Hail damage isn’t always dramatic. A roof can look fine from the driveway while individual tiles, flashings or metal surfaces have been affected. Large hail is specifically recognised by the Bureau as one of the defining features of a severe thunderstorm. Wind can create another set of problems. A few displaced tiles may not seem urgent, but an opening in the roof can allow rain into the roof space during the next weather event.
Internal and Structural Signs
The inside of the house often tells a different story. An inspection following a storm may look for:
- New ceiling stains.
- Damp patches around windows or external walls.
- Bubbling or damaged paint.
- Swollen plasterboard or skirting.
- Musty smells suggesting moisture has entered.
- Fresh cracks around openings.
- Changes in existing cracking.
- Moisture in affected wall or ceiling areas.
A ceiling stain that appears several days after a storm shouldn’t automatically be dismissed because the roof has dried out. Water can travel along roof timbers or within ceiling spaces before becoming visible inside the room. By the time the stain appears, the original entry point may be somewhere else.
That’s why timing matters.
An inspector can document the visible condition, identify areas requiring further investigation and help establish what has changed following the weather event.
Heatwaves and Ground Movement: The Less Obvious Risk
Storm damage is easy to understand because the event itself is obvious. Heat-related building movement is different. Extended periods of dry weather can affect moisture levels in reactive soils. As these soils dry, they can shrink. If the soil beneath part of a house moves differently from another area, the footing and structure above can experience stress.
This can contribute to cracking around brickwork, windows, doors and internal finishes.
The tricky part is that cracking doesn’t always appear suddenly. A homeowner may notice a small crack one summer, see it close or become less noticeable during wetter conditions, and then notice it again during the next dry period. That pattern can provide useful information about how the building is responding to seasonal ground conditions.
It doesn’t automatically mean there is major structural damage.
A building inspector will consider the location, size, direction and pattern of cracking alongside other observations. Doors that suddenly become difficult to close, sloping floors, gaps around frames and changes to existing cracks can all provide additional context.
Why Inspection Timing Matters
If you’re concerned about movement, an inspection during or shortly after a prolonged dry period may provide a different picture from one carried out after several months of wetter conditions. That doesn’t mean there is one perfect time to inspect a property. Rather, the timing and weather conditions at the time of inspection should be recorded as part of the overall assessment. If movement is suspected, monitoring over time may also be recommended rather than relying on a single snapshot.
For homeowners with older properties, keeping dated photographs of significant cracks can be useful. If a crack changes, you have something to compare against rather than relying on memory.
When to Get an Inspection: Before a Claim, Not Just After
After major weather damage, the first priority is safety. If a tree has fallen onto a property, a roof is significantly damaged or there is an immediate risk to occupants, the appropriate emergency service should be contacted. VICSES specifically advises calling 132 500 for certain storm-related emergencies, including significant roof damage or a tree causing structural damage.
Once the immediate danger has been dealt with, documenting the property’s condition becomes important. This is where an independent building inspection can be useful.
Why an Independent Inspection Can Help
A third-party inspector would be able to observe the damage to the building elements and condition of the said building elements that do not necessarily fall under their responsibility of making the repairs. This is an important distinction to make when you are trying to evaluate what has happened to your property and what needs to be done.
An inspection report could contain information on roof damage, water infiltration, crack formation, damaged exterior building elements, and other issues that can be observed. It will serve as the additional documentation that will help in discussing your case with the insurer but it does not replace the insurer’s investigation and claim processing procedure. There is a difference between the roles of an insurer’s investigator and a third-party inspector that evaluates the condition of the building. The former is investigating the case in order to decide whether the damage is insured and caused by certain events.
Don’t Wait Until the Damage Gets Worse
If a storm has damaged part of the roof, waiting for the next heavy rainfall can turn a relatively contained problem into a moisture issue. A small roof opening can allow water into insulation, ceiling materials or timber components. Repeated moisture can then create secondary problems. The same principle applies to drainage.
VICSES recommends keeping gutters, downpipes and drains clear because blocked drainage can contribute to storm-related flooding and property damage.
Documenting the Property Before Storm Season
There is also value in documenting the property’s condition before a severe weather event occurs. Dated photographs of the roof, gutters, external walls, retaining walls and other vulnerable areas can provide a useful baseline. This is particularly helpful for properties with existing cracks or older building components.
You don’t need to photograph every square metre of the house.
The useful approach is to record areas that already have visible defects or are likely to be affected by severe weather. If something changes later, you have a clearer point of comparison.
Building a Weather-Resilience Maintenance Habit
Most storm-related building problems are easier to deal with when they’re found early. That doesn’t mean homeowners need to inspect their roof every weekend. A few sensible checks before the wetter and stormier periods can identify simple problems before they become expensive ones.
Check Gutters and Downpipes
Leaves, dirt and other debris can restrict water flow. Before periods of heavy rain, check that gutters are clear and downpipes are draining properly. Look for sagging gutters, loose connections and water overflowing from places where it shouldn’t.
VICSES specifically recommends keeping gutters, downpipes and drains clear as part of storm preparation.
Keep an Eye on the Roof
From ground level, look for obvious changes such as missing tiles, damaged ridge capping or anything that appears loose. Don’t climb onto the roof to investigate suspected storm damage yourself. Roof inspections can involve genuine fall risks, particularly when surfaces are wet or damaged. If something looks out of place, have it assessed safely.
Check Drainage Around the Property
Water should have somewhere to go. Look at areas where water tends to collect after heavy rain. Pay attention to blocked surface drains, overflowing downpipes and soil or paving that directs water towards the house. Older Melbourne properties can have drainage arrangements that have changed over time as extensions, paving and landscaping were added.
Know When a Routine Check Isn’t Enough
A blocked gutter is one thing. A new ceiling stain, significant cracking, persistent dampness or visible roof damage is another. If a severe weather event has affected the property and you aren’t sure whether what you’re seeing is cosmetic or more serious, a building inspection can provide a more useful assessment than trying to judge the damage yourself.
The same applies when a property already has a history of movement or moisture problems. A post-storm inspection can be a good opportunity to assess whether the latest event has changed the condition of the building.
Frequently Asked Questions
Should I get a building inspection after a hailstorm in Melbourne?
Yes, particularly after a significant hailstorm or when you notice new damage. Hail can affect roof tiles, metal roofing, skylights, gutters and other external components without the damage being obvious from ground level.
An inspection can document the condition of the affected areas and identify signs of water entry before they develop into larger problems.
Can heatwaves cause structural damage to Melbourne homes?
Extended hot and dry conditions can contribute to changes in moisture-sensitive soils, which may affect footing movement in some properties.
The risk varies depending on the site’s soil conditions, foundation type, drainage and existing condition. Cracking alone doesn’t prove structural damage, so changes in cracking should be considered alongside other signs such as uneven floors or sticking doors.
Does a building inspection replace an insurance assessor’s report?
No. An independent building inspection and an insurer’s assessment serve different purposes.
A building inspector can document observable damage and building condition, while the insurer’s assessor determines the extent of the insured loss under the relevant policy and claim process. An independent report may support your documentation, but it doesn’t replace the insurer’s assessment.
How soon after a storm should I book an inspection?
As soon as practical, particularly if you can see new damage, water entry or changes to the building. Prompt documentation can help establish what the property looked like following the event. If the property is unsafe, however, don’t enter damaged areas simply to obtain photographs or inspect the damage yourself. Safety comes first.
A Storm Doesn’t Always Leave Obvious Damage
The most noticeable storm damage is usually the easiest to spot. A broken tile, fallen branch or damaged gutter is hard to miss.
The less obvious problems can take longer to appear.
A small roof leak, moisture trapped within a ceiling space or a crack that has changed after a period of dry weather may not attract much attention at first. Given Melbourne’s mix of older homes, variable weather and properties built on different soil conditions, the same storm can affect two houses quite differently. That is why a post-storm inspection isn’t simply about looking for obvious damage. It is about documenting the property’s condition, identifying areas that need attention and deciding whether further investigation or repair is warranted.
For homeowners, that information can make the next step much clearer.
Planning a Property Inspection After Extreme Weather?
In the case that your property in Melbourne has been subjected to any severe storms, hailstorms or extreme heat, it may be useful to get a building inspection to identify the changes and issues that need further consideration. Building inspection services are provided by Guardian Building Inspections throughout Melbourne. The inspection is done based on certain aspects including roofing, moisture, cracking, drainage, and other building defects. It is better to assess the building when the signs of the damage are still evident, rather than wait until the next storm reveals the issue.
