Preparing your home for extreme weather: people first, hazard by hazard

Prepare a household plan before severe weather, including safe destinations, transport, communication and individual needs. Plan to act early; do not assume an official warning will arrive before flash flooding. Follow current local emergency directions. Assess storm, flood, bushfire and heat risks for the particular home, arranging competent property work in calm conditions. Confirm any proposed insurance benefit with the insurer.

Plan to act early. Do not assume a warning will arrive before flash flooding; follow current local emergency guidance.

The order is people, warnings, property

  1. People: decide who does what, where you will go, when you will leave and how children, older people, disability, medication and pets are supported.
  2. Warnings: use the official emergency service and hazard authority for your location; understand warning levels before the event.
  3. Property: assess the specific storm, flood or bushfire mechanism and complete competent work in calm conditions.
  4. Records and insurance: keep photographs and invoices, update the rebuild basis, and ask the insurer about cover, excesses and recognised mitigation.

The NSW Rural Fire Service survival plan says leaving early is the safest option and calls for a prepared plan. Follow the current authority for your state or territory during an event.

Storm and wind

Before storm season, use safe ground-level observation and competent inspection to identify loose roof material, deteriorated flashings, blocked or failing rainwater goods, vulnerable openings, hazardous trees and unsecured outdoor objects. VICSES advises maintaining the home and yard, clearing gutters and securing loose items. Use trained, equipped people for roof access. Stay clear of fallen powerlines and floodwater.

Flood

Flood depth, velocity, duration, contamination and access vary by location. Start with the council or state flood authority and property-specific information. VICSES warns that flash flooding can develop without an official warning. Plan early and never enter floodwater. Discuss property measures, service vulnerabilities and lawful drainage with qualified professionals before an event; no measure guarantees that a home will remain dry or accessible.

Stay out of floodwater and follow official power-safety advice. After inundation, treat water and affected materials as potentially contaminated and follow emergency, electrical and public-health instructions before re-entry.

Bushfire and ember attack

Begin with a survival plan and the local fire authority. Determine whether the property is in bushfire-prone land and whether a Bushfire Attack Level or planning control applies. Building measures depend on the assessed exposure, construction and local rules.

Preparation can include lawful fuel and vegetation management, clear gutters, maintained decks and subfloors, sealed gaps and compliant non-combustible mesh at openings. Keep required ventilation paths, cavity drainage and weep holes clear. On catastrophic or extreme conditions, follow official advice and leave early.

Confirm insurance outcomes in writing

Before major resilience work, ask the insurer or broker what evidence it requires (see home condition and insurance), whether the measure changes cover or excess, and whether construction must be notified. Review flood, storm, bushfire, actions-of-the-sea and temporary-accommodation definitions using Moneysmart's hazard insurance guide.

The property record to keep

  • Official hazard maps, BAL or flood information and the date accessed.
  • Emergency plan, contacts, routes, medication and pet arrangements.
  • Dated photographs of roof, elevations, drainage, openings, yard and critical equipment.
  • Inspection reports, design advice, approvals, invoices, product specifications and warranties for resilience work.
  • Insurance schedule, PDS version, endorsements and written insurer responses about mitigation.

Heat is a building and household risk too

A home can become difficult to occupy without visible storm damage. Victoria's health department identifies extreme heat as a health risk that can also disrupt power and services. Include a plan for vulnerable household members and follow current health guidance. An air conditioner is useful equipment, but it is not a complete plan if electricity or transport fails.

Before hot weather, identify which rooms overheat, when direct sun enters and whether shading and cooling equipment function. Consider access to a cooler safe place and how you will get there if normal arrangements fail. For lasting improvements, have a competent designer assess shading, insulation, ventilation and the particular construction. Opening windows is not always helpful when outside conditions are hotter or smoke-affected; the strategy must respond to actual conditions.

Read the address, not just the hazard label

A map is a starting point for property questions. Ask which hazard and scenario it represents, its date, whether it describes land or floor exposure, and how access might be affected. A home above a mapped flood extent may still have a vulnerable access route or local overland-flow problem. An omitted area is not a professional finding that every hazard is absent.

Construction changes the questions. A raised timber home may have habitable rooms clear of ground water while services or enclosed spaces below remain exposed. An apartment can depend on basement pumps, lifts and shared electrical equipment. A lightweight extension and the original masonry home may behave differently in wind and heat. Use these distinctions to commission assessment, not to assign a safety rating from era or listing photographs.

After an eventConfirm safe access and obtain the appropriate damage and service checksA dry-looking room does not establish that concealed materials or electricity are safe
Separate three different kinds of preparation

Plan for a failure of the first plan

List the assumptions behind your preparations. Does a garage door need power to open? Does the household rely on one driver, one mobile network or a lift? Does a pump require electricity during the same event that might interrupt it? Review these dependencies in calm conditions with the appropriate professional or service provider. Do not improvise electrical connections or generator arrangements during an emergency.

Discuss access and responsibilities in a strata scheme before the season. An owner may be able to secure items on their balcony while roof repairs, tree work or drainage alterations require scheme decisions. Record outstanding work and who has responsibility for it. Link this to the strata risks for owners guide; a shared system is not maintained simply because each owner has checked their own unit.

Recovery starts with safe access and a clear chronology

Use the relevant emergency authority's advice before re-entry, and competent assessment for damaged structures or services. Document the event and visible damage only where safe, then retain the records of emergency work and insurer directions. Explain what existed before the event, what was first seen afterwards and what remains uncertain. An event occurring before a symptom is evidence of timing; it does not by itself establish the full cause or insurance outcome. Keep that chronology with the original files using the home-record guide.

A repair plan should distinguish immediate protection, drying or contamination assessment, permanent repairs and the evidence needed before finishes close the affected area. Discuss the scope with the insurer and the responsible professionals. Repainting alone cannot establish that a concealed moisture problem has been resolved. The moisture guide helps frame the investigation questions without turning a photograph into a diagnosis.

Worked example: a clean gutter and water at the door

Illustrative reasoning example, not an inspected property. A household has recently cleaned its gutters. During heavy rain, water reaches a rear doorway and a nearby street becomes difficult to access. The owners conclude that larger gutters will solve the problem.

Cleaning is evidence of one maintenance task, not proof of the capacity or operation of the entire drainage system. Roof discharge, surface falls and wider water movement are separate possibilities. During the event, household safety and official instructions take priority; no one should enter floodwater to test the theory.

Later, a drainage professional can examine the property and lawful discharge, while local flood information helps explain wider exposure and access. A defined finding may support gutter work, another intervention or several measures. The household plan also needs review, because keeping the floor dry would not necessarily keep the access route usable.

Keep conclusions at the level the evidence supports: observed, reported, inferred or confirmed. An unavailable document is a gap in the record; it does not prove the work was never done.

Frequently asked questions

What is the first step in extreme-weather preparation?

Prepare the household plan, destinations and official information sources before the building checklist. Include transport, communication, medication, disability needs and pets. Plan to act early; flash flooding may develop without an official warning. Follow current local emergency guidance.

What should I do before storm season?

From safe locations, check for roof, drainage, tree, opening and loose-object risks; arrange competent inspection and repair where needed. Never work on a roof during a storm or approach fallen powerlines.

Should I install flood barriers?

Only after property-specific flood and professional advice. Depth, velocity, duration, contamination and drainage interactions matter, and a barrier can redirect water or fail if misapplied.

How do I protect vents and weep holes from embers?

Use bushfire-compliant, non-combustible mesh and details suited to the assessed exposure without blocking required drainage or ventilation. Confirm the applicable BAL, standard and local requirements.

Will resilience work lower my insurance premium?

Ask the insurer what it recognises, what evidence it needs and whether cover or excess changes before spending for an insurance outcome.

Should I wait for a flood warning before acting?

No. Flash flooding can develop without an official warning. Prepare early, know local conditions and follow current emergency guidance; never enter floodwater.

Does an air conditioner complete my heatwave preparation?

No. Include household needs and a safe alternative if power or cooling fails, following current health advice. Building improvements and equipment maintenance are longer-term parts of the plan.

Does being outside a mapped hazard area mean my home is safe?

A map has a defined purpose, coverage and scenario. Check property and access conditions; absence from one map does not establish absence of every hazard.
