Storm-Proofing Your Home: A Practical Pre-Season Checklist

Vietnam's storm season rarely arrives without warning. The north takes the brunt around mid-year, central provinces are hit hardest late in the year, and the south lives with prolonged heavy rain and tidal flooding through the second half. What catches people off guard is not the weather — it is realising the house was never made ready. Here is a practical checklist you can finish over a couple of weekends that prevents most of the familiar damage: lifted roofing, flooding, electrical faults and lingering damp.

Start with the roof

The roof is where damage begins and where repairs get expensive once the rain has started. Pick a dry morning, work with a second person, use a solid ladder.

• Metal sheeting: retighten every screw and replace rusted ones plus rubber washers gone hard in the sun — the most common source of leaks, and the easiest to fix.
• Edges and eaves: wind always attacks from the perimeter. Add clamps, battens or edge trim, especially on single-storey homes and rear patio covers.
• Tiles: look for slipped, cracked or missing pieces and repoint the mortar at ridges and valleys.
• Plastic panels and removable awnings: the first things to fly away. If you cannot fix them down properly, plan to take them down when wind is forecast.

Don't inspect from the ground only: many leaks show up as a stain on a ceiling or daylight through a gap in the attic.

Prune the trees around the house

Falling branches do two kinds of damage: direct hits on roofs, walls and vehicles, and downed lines that black out a whole street.

• Remove dead, rotting or overhanging limbs, particularly those above the roof or near cables.
• Thin the canopy so wind passes through instead of pushing against a dense sail.
• Watch for brittle species, shallow roots and anything planted in a narrow bed — these uproot most easily.
• Decide in advance where large pots, trellises and signboards get moved or tied down.

Do this early. Once a warning is issued, tree crews are booked out.

Clear drains and gutters

Much of what people call flooding is really water that could not drain fast enough.

• Scoop leaves, silt and rubbish out of gutters, then check the downpipe elbows for clogs.
• Pour a bucket of water through as a test: slow draining or overflow means trouble.
• Clear yard drains, balcony and rooftop outlets, and the manhole in front of the house.
• If your floor sits below street level, prepare a threshold barrier or sandbags now rather than later.

Seal walls, windows and doors

Damp doesn't arrive during the storm — it stays for months afterwards. Walk the exterior and fill hairline cracks, especially on the wall that catches driving rain. Recaulk window surrounds, the wall-to-roof junction and the base of balconies, and replace any window seal that has gone stiff. Old damp has to be treated from the outside; interior anti-mould paint is only a stopgap.

Electrics and appliances

Leave the wiring itself to a qualified electrician, but plenty stays in a homeowner's hands:

• Confirm the house has a residual current breaker and press its test button.
• Raise ground-floor sockets and switchboards above the highest water level your area has seen.
• Unplug expensive equipment during thunderstorms; a surge-protected power strip is cheap insurance.
• Lift outdoor air-conditioner units, pumps and washing machines onto plinths.
• If water gets inside, switch off the main breaker before wading in to clean up.

Raise your belongings in flood-prone areas

If your street has flooded before, treat the highest recorded level as your benchmark and keep anything important 30–40 cm above it: outlets, fridge, washing machine, books, documents, particle-board furniture, motorbikes. Use steel shelving, plastic pallets or concrete plinths rather than stacked bricks, and pack vulnerable items into sealed bins. In a multi-storey house, agree in advance which upstairs room becomes the safe zone.

Build one emergency bag

A single bag, stored where everyone in the family knows to find it, covering roughly three days:

• Drinking water and food that needs no cooking.
• Everyday and prescription medication, plus a basic first-aid kit.
• Torch, spare batteries, a charged power bank and a small battery radio.
• Copies of documents, small-denomination cash and a handwritten list of phone numbers.
• Rain gear, dry clothes, towels, rubber sandals and waterproof pouches for phones.
• Separate supplies for infants, elderly relatives and pets.

Review the bag once a year — flat batteries and expired medicine are the norm, not the exception.

Protect your paperwork

Photograph property titles, insurance policies, birth certificates and medical records, then store them in the cloud or email them to yourself. Keep originals in a waterproof box somewhere high and easy to grab. If you carry property insurance, photograph the house and its contents before the season starts; that set of images makes proving a loss far simpler later.

Do it early, not when the warning arrives

The difference is less what you do than when. By the time an alert is broadcast, sandbags are sold out, tradespeople are unavailable and you have time only for the bare minimum. Split the list in two: handle the structural work — roof, trees, drainage, sealing, electrics — at the start of the season, then run the quick routine whenever wind is forecast: bring outdoor items in, charge everything, lift furniture, check the bag.

Along the central coast, where strong wind arrives early and in clusters, the forecast for Quang Binh and its neighbours helps you time the reinforcement work. In southern cities, trouble comes from heavy rain meeting high tides, so the rain outlook for Ho Chi Minh City is worth a glance each afternoon. Once the house is ready, all that's left is to check tomorrow's forecast and sleep well.
