How to manage and prevent strata common property storm damage

A practical guide to storm property maintenance to help protect your building, reduce risk, and respond effectively when extreme weather hits.

Storms, heavy rainfall, strong winds, and flooding can cause significant damage to strata and body corporate properties, leading to water ingress and affecting both common property and individual lots. Without proper preparation and processes, these weather events can cause damage that may lead to costly repairs, lengthy recovery processes, and even safety hazards for residents.

With a higher chance of tropical storms during the warmer months, now’s the time to check your building’s weather readiness. This article provides a practical guide for strata owners and committees on managing storm and flood damage, covering responsibilities, legal obligations, insurance issues, emergency responses, and preventative strategies.

Here is what you need to know to help prevent, prepare and respond to common property storm damages:

Australia’s high-risk weather season

From October to April, Australia enters its high-risk weather season, when the likelihood of bushfires, heatwaves, floods, and tropical cyclones significantly increases. These extreme weather events can develop rapidly, causing significant disruptions and damage to homes, infrastructure, and communities.

With climate conditions becoming more volatile, frequent and intense, strengthening preparedness and response capabilities is essential for communities in high-risk areas across the far north, eastern and coastal Australian regions.


Why early preparation matters

Acting before disaster strikes can help:

  • Reduce damage to property and infrastructure.
  • Minimise recovery time and costs.
  • Improve coordination across emergency services and communities.

Common challenges for strata properties

Unlike standalone homes, strata, owners’ corporation, and body corporate buildings involve shared ownership of common property such as roofs, gutters, basements, gardens, car parks, and external walls. When storm or flood damage occurs, it often affects both private lots and common property, which makes dividing responsibilities complex. It’s important to note that responsibilities can be difficult to define, as they may vary for each property depending on the individual strata plans or by-laws and building rules.

Below is an overview of key challenges that strata, owner’s corporation, or body corporate communities encounter with storm damage:


1. Shared infrastructure

Storm damage to common property, like roofs, drainage systems, or external walls, can impact multiple lots. A single point of failure may lead to widespread issues, requiring coordinated repairs and funding.


2. Complex ownership boundaries

Determining what falls under common property versus individual lot responsibility isn’t always straightforward. This can lead to confusion or disputes over who pays for what, especially when damage crosses boundaries.


3. Multiple stakeholders

Owners corporations, body corporates, committees, and strata managers must work together to assess damage, approve repairs, and communicate with contractors. Delays or miscommunication between these parties can slow response times and worsen the damage.


4. Regulatory compliance

Repairs must meet current building codes, waterproofing standards, and safety regulations. Older buildings may have outdated infrastructure or existing defects that complicate compliance and increase repair costs.

The difference between storms, floods, and extreme weather damage

Australia’s climate is diverse and dynamic, ranging from tropical and subtropical zones to temperate regions with seasonal wet periods. This means severe weather events like heavy rainfall, storms, and cyclones are not rare occurrences, but ongoing risks that strata, owners corporation, and body corporate properties must be prepared for. Understanding the types of weather-related damage is key to managing risk and navigating the recovery process:

Storm damage typically results from intense rainfall that overwhelms drainage systems.

Water that escapes from drains, gutters, or channels due to intense rainfall and overwhelmed drainage systems. It typically flows over land and into buildings with nowhere else to go.

Flooding occurs when water that escapes from natural or artificial water bodies, such as rivers, dams, creeks, lakes, or reservoirs, usually covering dry land.

The Insurance Council of Australia officially declared a severe weather event as catastrophic.

These events may trigger special insurance conditions or additional coverage under catastrophe clauses.

Common types of damage:

  • Strata water damage: Water ingress from roofs, balconies, or walls is often caused by poor waterproofing or construction defects. These leaks can lead to internal damage, disputes over repair responsibilities, and long-term structural issues.
  • Flooding: Basement garages, storage rooms, and lifts are especially at risk during heavy rain or storm events. Inadequate drainage or blocked stormwater systems can result in significant water accumulation and property damage.
  • Damage to shared infrastructure: Electrical systems, pumps, fire safety equipment, and lifts may be compromised by water exposure or general wear and tear, affecting the safety and functionality of the entire building.
  • Mould and health hazards: If water damage isn’t promptly addressed, mould can develop in wall cavities, ceilings, and flooring. This poses serious health risks to occupants and can require costly remediation.

Common areas impacted:

  • Roofs and gutters: Damaged tiles, blocked downpipes, or deteriorated waterproof membranes can lead to leaks and water pooling.
  • Balconies and terraces: Poor drainage or failed waterproofing systems often result in water seepage into adjoining units or common areas.
  • Basements and car parks: These areas are prone to flooding when stormwater systems back up or are overwhelmed during extreme weather.
  • Windows and external walls: Gaps, cracks, or degraded sealants allow wind-driven rain to penetrate, leading to internal water damage and mould growth.
  • Stormwater drains: Blockages or insufficient capacity during heavy rainfall can cause overflow and flooding throughout lower levels of the building.

Who is responsible for storm damage repairs and maintenance

Understanding who handles repairs after a storm or severe weather event can be one of the more complex aspects of strata, owner’s corporation, or body corporate living. Damages, especially water ingress, may begin in one location and spread across several lots and common property, making it difficult to determine who should act. Responsibilities can vary depending on your scheme’s strata plan and by-laws or building rules. When unsure who should handle a repair, your strata, owner’s corporation, or body corporate manager is the best person to clarify obligations and coordinate next steps.

The general principle is:

  • Owners corporations or body corporates: are typically responsible for common property including the property’s structure, roof, external walls, shared plumbing, gutters, drainage, balconies (shared), shared waterproofing membranes, etc.
  • Lot owners: are typically responsible for interiors of their lot, such as internal walls/fittings/fixtures/appliances, internal plumbing (in some cases), sealing and waterproofing internal bathrooms, etc., and maintenance within their defined lot boundary.

The importance of preventative maintenance for storm damage

While no one can control the weather, preventative maintenance is the most effective way to reduce the risk of storm and weather damage. Proactive measures not only protect property and save money but also help maintain the safety and resilience of communities. Preventive maintenance means taking regular, proactive steps to keep your property resilient against storms and floods. This includes inspecting, repairing, and upgrading structures and systems before problems arise.

Roof and membranes

  • Inspect the roof at least once annually and after every major storm.
  • Replace missing tiles, repair flashing, and reseal membranes.
  • Check for cracks or damage around roof penetrations (vents, exhausts, antennae).


Gutters, downpipes, and drains

  • Clean gutters and downpipes twice yearly, and more often if surrounded by trees.
  • Clear drains and direct stormwater away from the building.
  • Install gutter guards or leaf diverters to reduce blockages.


Balconies and waterproofing

  • Check balcony drainage outlets for blockages.
  • Inspect waterproof membranes for signs of cracking, ponding, or peeling.
  • Verify that balconies slope outward to prevent water pooling.


Basements and car parks

  • Test sump pumps, drainage pits, and backup generators before the wet season.
  • Check flood barriers, grates, and access points for vulnerabilities.
  • Maintain clear signage and evacuation procedures for residents and vehicles.


Seal windows, walls, and doors

  • Re-caulk and reseal around windows and doors.
  • Repair cracks in render, cladding, or brickwork.
  • Adequately seal vents, louvres, and service penetrations.


Trim trees and overhanging branches

  • Remove overhanging branches near roofs and balconies to reduce storm and fire hazards.
  • Maintain defensible space in bushfire-prone areas.
  • Check that pathways and common gardens have adequate drainage to prevent pooling.


Building resilience upgrades

  • Install storm shutters or laminated glass in cyclone-prone regions.
  • Fit ember guards on vents and seal gaps in bushfire zones.
  • Solar battery storage or generators should be considered to maintain essential services during outages.

Preparing your lift or elevator

Terry and the Elevator Direction team have kindly provided some general information to assist with preparing lifts during a cyclone or flooding event. In some cases, stopping flood water from entering lift pits will not be possible, but ensuring that water comes into contact with as few components as possible will save remediation costs and reduce the unit’s downtime.

Isolating the lift on the top floor seems like the best solution, but in some cases, this can cause avoidable damage.

On traction lifts, when the lift car is at the top of the shaft, the counterweight will be at the lowest point in the shaft.

This may mean that the counterweight is submerged, and, in extreme cases, the hoist ropes may also become submerged. This could mean additional avoidable repairs will be required.

If your building is likely to flood, Elevator Direction provide the following guidance:

  • Help ensure that the building is empty and that the lifts are not required to transport people out of the building. If the building is occupied, it may be best to leave one lift in service.
  • Take the lift(s) to a floor approximately halfway up the building.
  • Key the lift(s) to independent or exclusive service – do not key the lift to fire service.
  • If the lift serves only two floors or is a hydraulic lift, take that lift to the top floor and isolate it.

This is general guidance and does not consider each building’s individual needs. If you want to discuss your circumstances, please contact Elevator Direction.

Shutdown solar systems

  • Temporarily shut down solar panel operations during a cyclone. Each system might require slightly different steps, and it’s always best to review the manual or the installer’s shutdown procedure. 
  • Advise employees and residents against securing or repairing solar panels themselves. 
  • Don’t climb on rooftops during inclement weather for safety reasons – the roof could be live due to electrical hazards or a heavy load. 
  • Contact professional solar technicians for necessary inspections or repairs once it’s safe. 
  • Prevent manual restart of the solar system after the cyclone without proper safety clearance. 
  • Maintain focus on everyone’s safety and the system’s integrity in hazardous situations. 
  • Treat all solar panels and safety cables as live and dangerous.

Information about fire detection or alarm systems

Fire detection, alarm systems, or sprinkler systems could potentially be affected by flooding or power outages and, therefore, the ability to transmit alarm signals may be compromised.  

In some instances, a systems backup battery may only last 24 hours once power is lost. 

In an emergency, building occupants should contact 000. 

How to respond to common property damage after a weather event  

While storms and extreme weather events may be beyond anyone’s control, how an owner’s corporation or body corporate responds in the immediate aftermath can significantly reduce further harm, speed up recovery, and protect residents. Acting quickly, safely, and in coordination is key.

Prioritise safety first

Promptly address any immediate dangers, such as fallen debris, broken glass, and electrical hazards where water has reached wiring/power points.

If parts of the building are compromised (roof sections, large leaks etc.), consider evacuation or restriction of affected areas and contact emergency services if lives are at risk:

  • SES (storm/flood assistance): 132 500
  • Triple Zero (000) for life-threatening emergencies

Record and document the damage

  • Once safe, take clear photos and video of all storm-related damage.
  • Record the time, date, and suspected source of water ingress (e.g. roof, windows, plumbing).
  • If safe to do so, isolate the issue (e.g. shut off water or apply temporary coverings).

Notify relevant parties quickly

  • The owner’s corporation or body corporate should contact the committee, strata or building manager immediately. Many insurance policies require prompt notification, and delayed notice can sometimes lead to denial or reduction of claims. 
  • Inform lot owners and residents, especially if damage may affect multiple units.

Mitigate further damage

If necessary, take reasonable steps to prevent further loss, such as:

  • Addressing electrical hazards.
  • Performing emergency roof repairs or applying tarps.
  • Securing broken glass or windows.
  • Restricting access to unsafe areas.
  • Removing hazardous debris. 

Engage professionals early

Insurers may often require expert reports. Engaging qualified trades or building assessors through your strata, body corporate, or owner’s corporation managing agent can help establish the cause and extent of damage for the recovery process.

Navigating the storm damage recovery process

Strata insurance claims

Strata or building insurance, managed by the owner’s corporation or body corporate, is mandatory in all states and covers the building structure, common property, and shared contents. However, coverage varies between policies. For example, some policies include extras such as flood or catastrophe cover, while others may not. Understanding your policy helps ensure faster, more accurate claims.


Contents insurance claims

Strata insurance does not cover personal belongings inside your unit such as furniture, electronics, clothing, appliances and floor coverings. Lot owners and tenants should have their own policy to avoid costly out-of-pocket losses.
