Rainy Season Prep Checklist for Filipino Homes: A Practical Guide

Preparing for rainy season in the Philippines is not dramatic — it is practical. The country experiences 20 or so typhoons a year on average, with the heaviest weather concentrated between July and October. Most years, the rains are manageable. Some years, they are not. Either way, a home that is prepared handles both outcomes better than one that is not.

This checklist is organized by area: structure and outdoor, utilities and power, emergency supplies, documents and valuables, health, and daily life. Work through it before the season peaks, and you will have far fewer problems to deal with in the middle of a storm.

Rainy season prep in the Philippines is also about peace of mind. Knowing your roof is checked, your supplies are in place, and your documents are protected means you can focus on your family when a typhoon warning is issued — rather than scrambling to buy flashlights when every hardware store is already sold out.

Part 1: Structure and outdoor

This is the most important category — water damage and flooding start at the structure level.

✅ Inspect your roof

Look for:

• Missing, cracked, or broken roof tiles or sheets
• Visible rust on metal roofing, particularly around nail holes and seams
• Soft spots or sagging in flat or interior portions
• Water stains on ceilings — a sign of previous leaks

If you rent, this is a good time to notify your landlord of any issues in writing (message or email) so the responsibility is clear before damage occurs.

When to hire help: Roof repair in the Philippines is inexpensive before the rains begin and expensive — or impossible to schedule — once the season starts. If you see damage, act now.

✅ Clear your gutters and drainage

Clogged gutters and drains are the most preventable cause of home flooding. Before rainy season:

• Clear leaves, debris, and sediment from roof gutters and downspouts
• Check that downspouts direct water away from the foundation, not toward it
• Clear any blocked drainage channels in your yard or around the house perimeter
• If your area floods, identify which drainage channels or canals are your home's primary exit point and make sure they are not blocked at the entry point to your property

✅ Check windows and doors for gaps and leaks

Heavy rain driven by typhoon winds enters through gaps around window frames, under doors, and around air conditioning units. Check:

• Window seals — apply weatherstripping or caulk around gaps
• Under-door gaps — a door sweep or an old rolled towel addresses immediate leaks; a more permanent fix is a rubber door seal strip
• Air conditioning units — water can enter around improperly sealed wall units during heavy lateral rain

✅ Secure outdoor items

Items left outside become projectiles in strong winds. Before a typhoon or heavy storm:

• Bring in or secure potted plants, garden furniture, and hanging items
• Secure anything mounted to exterior walls or fences
• If you have large trees or branches that hang close to the house, arrange for trimming before the season

Part 2: Utilities and power

✅ Test your flashlights

The single most common domestic disaster during storms is the power going out with no working flashlights in the house. Check:

• Do all your flashlights work?
• Do they have fresh batteries?
• Do you have spare batteries in reserve?

A headlamp is particularly useful because it frees your hands. If you do not have one, they are available at hardware stores and on Lazada/Shopee for ₱150-₱500.

✅ Charge your power banks and backup devices

Power banks have become standard Philippine household equipment. Before a storm:

• Charge all power banks to full
• Make sure you know where your charging cables are
• Identify a plan for extending phone battery life during a multi-hour outage: lower screen brightness, turn off wifi/data when not needed, avoid video streaming

✅ Prepare candles and matches

A backup to your flashlight. Keep a supply of candles and a reliable lighter or matches in a dry, accessible location. Never leave candles unattended.

✅ Know your circuit breaker

During floods, the single most important thing to do with electricity is turn it off. Know where your circuit breaker panel is, how to turn off the main breaker, and what the individual circuits control. If water enters your home during a flood, cut power before wading through water near electrical outlets or appliances.

✅ Gas safety

If your home uses LPG, check the hose and connection for wear, cracks, or loose fittings. A leaking gas hose is a fire and explosion risk; replace it if it shows any damage.

Part 3: Emergency supplies

✅ Emergency food supply

You should have at minimum 3 days of food that does not require refrigeration or cooking:

• Canned goods (sardines, corned beef, tuna, beans)
• Instant noodles, instant rice, crackers
• Biscuits, energy bars
• Salt and sugar (for oral rehydration solution, if needed)

Rotate your stock — check expiry dates and replace anything that is close to expiring.

✅ Clean drinking water

Store at least 3 liters per person per day for 3 days. Options:

• Sealed commercial bottled water
• Refilled water jugs stored in clean, sealed containers
• A water purification method (iodine tablets, water filter, or a filter straw) as backup

If your area is flood-prone, double this amount — flooding can disrupt water supply and contaminate water systems for days.

✅ Basic first-aid kit

At minimum:

• Paracetamol and ibuprofen (fever, pain)
• Oral rehydration salts (diarrhea and dehydration)
• Antihistamine
• Antiseptic (Betadine or similar) and wound dressing materials
• Loperamide or similar (for diarrhea common after flood exposure)
• Prescription medicines for any family member who takes them regularly — maintain at least a 2-week supply

Part 4: Documents and valuables

✅ Waterproof your important documents

Documents destroyed by flooding are extremely difficult and time-consuming to replace. Protect:

• Birth certificates, marriage certificates
• Land titles and property documents
• PhilSys ID, passport, driver's license, SSS/GSIS/PhilHealth cards
• Insurance documents
• School and employment records

How to protect them:

• Store originals in a waterproof sealed bag or plastic container with a tight lid
• Keep photocopies or scanned digital copies in cloud storage (Google Drive, iCloud, email to yourself)
• Place the physical container high up — on shelves, never on floors

✅ Back up your electronics

If you have a laptop, external hard drive, or phone with irreplaceable data:

• Back up to cloud storage or an external drive kept in a separate location
• Store your laptop in a padded, waterproof bag during storms
• Consider surge protection — a UPS (uninterruptible power supply) or surge protector protects electronics from power spikes when power is restored after an outage

Part 5: Health preparation

✅ Stock medicines for common rainy-season illnesses

Colds, flu, and stomach ailments are more common during rainy season. Stock:

• Paracetamol, ibuprofen
• Vitamin C (effervescent or tablet)
• Antihistamine for allergy flare-ups
• ORS sachets
• Antidiarrheal

✅ Reduce leptospirosis risk

Leptospirosis is transmitted through water or soil contaminated with infected animal urine. If you live in or near a flood-prone area:

• Avoid walking through floodwater if possible
• If you must, cover any cuts or wounds before doing so
• Wash thoroughly with clean water and soap immediately after exposure
• Seek medical attention for fever, muscle pain, or headache within 2 weeks of flood exposure

✅ Prevent dengue

Standing water breeds the Aedes aegypti mosquito, the dengue vector. Before rainy season:

• Empty, scrub, and cover water storage containers weekly
• Dispose of items that collect rainwater: old tires, unused plant pots, containers
• Use mosquito repellent, particularly for children playing outdoors

Part 6: Daily life and comfort

✅ Review your go-bag

If your area is typhoon-prone or in a flood-risk zone, maintain a go-bag ready for evacuation:

• Copies of important documents (in a waterproof pouch)
• Cash (ATMs may be non-functional)
• Phone, power bank, charger
• 1-2 changes of clothing
• 3-day supply of medicines
• Bottled water and snack foods
• Flashlight and batteries

✅ Check your insurance

If you have homeowner's or renter's insurance in the Philippines, review what is covered: flooding, typhoon damage, and water damage coverage vary significantly by policy. The time to understand your coverage is before something happens, not after.

✅ Know your evacuation center

If your barangay is flood-prone or in a typhoon risk zone, know:

• Where your designated barangay evacuation center is
• What the evacuation signal or announcement system is (barangay announcements, PAGASA advisories, local social media groups)
• Who in your household needs extra assistance during evacuation (elderly, infants, persons with disabilities)

Rainy season prep checklist summary

Frequently asked questions

When should I start rainy season prep in the Philippines?

Ideally in April or May, before the southwest monsoon arrives in June. Starting early gives you time to arrange roof repairs, restock supplies, and clear drainage without the urgency of an approaching storm.

What is the most important thing to prepare for rainy season?

Structural first: roof and drainage. If water enters your home, everything else is harder. After that, power backup (flashlights, power bank) and emergency water supply are most critical.

How much water should I store for rainy season?

At minimum 3 liters per person per day for 3 days. If your area is flood-prone, prepare for 5-7 days of water disruption.

How do I protect documents from flooding?

Store originals in a waterproof sealed container or bag, elevated off the floor. Keep scanned digital copies in cloud storage. A sealed plastic bin with a lid is inexpensive and effective.

What diseases are common during rainy season in the Philippines?

Leptospirosis (from flood water contact), dengue fever (from mosquito breeding in standing water), and respiratory illnesses (colds, flu, sometimes pneumonia from damp conditions) are the most common rainy-season health concerns.

What should my go-bag contain for typhoon evacuation?

Documents (copies in waterproof pouch), cash, phone and power bank, clothing change, 3-day medicine supply, bottled water, snacks, and a flashlight.
