Can a leaking roof be repaired while it's still raining?

Permanent repairs can't be done in the rain because the roof surface is slippery and sealant won't stick to wet surfaces. What a contractor can do is temporary protection, such as covering the leak area with a tarpaulin. Full roof leak repair is carried out once the weather is dry.

Why does my roof only leak during heavy rain, but not during light rain?

Heavy rain tests the full capacity of your roof system. Clogged roof gutters overflow, and strong winds push water in through flashing gaps or under roofing sheets. During light rain, water drains away before it can seep in — that's why the leak only shows up when the rain gets really heavy.

How do I find the source of a roof leak if I can't see any hole?

Water can travel along roof trusses and drip far from the actual entry point — which is why the drip location on your ceiling is usually not where the leak is. A roofing contractor will check the roof screws, flashing, ridge, and gutters to trace the real source. Send us photos via WhatsApp and we'll give an estimate within 30 minutes.

How much does a small roof leak repair cost?

Minor repairs such as patching a localized leak or replacing roof screws start from RM150, with a 1-year warranty. If cracked roof tiles are involved, repair costs typically range from RM200 - RM800. The actual price depends on the cause and extent of the damage, so an on-site inspection still matters.

Leaking Roof in Rainy Season? 5 Emergency Steps

Roof Suddenly Leaking? Don't Panic!

Malaysia's rainy season (November-March) often causes roof leaking problems. Hours of heavy rain, strong winds, and pooling water test every inch of your roof. If you suddenly spot water dripping from the ceiling, don't panic. Follow these 5 emergency steps first, then plan a proper repair.

Why Do Roofs Leak During Heavy Rain?

A leaking roof rarely happens without a cause. Most roof leak repairs we handle trace back to these issues:

Loose or rusty roof screws — the rubber washers on roofing screws harden and crack after years of heat. Water enters through the screw holes.

Damaged roof flashing — the joint between roof and wall is the most common leak point. Cracked cement or flashing lets water seep through.

Cracked or shifted roof tiles — strong winds can shift tiles out of position. One cracked tile is enough for water to get in.

Clogged roof gutters — dry leaves and debris make the gutter overflow back under the roof during heavy rain.

Rusted zinc sheets — old zinc roofs develop pinholes. A small drip today can become a major leak next month.

Worn waterproofing layer — on flat concrete roofs, an aged waterproof coating loses its ability to hold back pooling water.

Step 1: Place Buckets or Containers

First thing — place a bucket or container under the leak to stop water spreading to floors and furniture. If the drip is fast, put a cloth inside the bucket so water doesn't splash out. Check other rooms too; a leaking roof rarely leaks at just one point.

Step 2: Move Electronics Away

Immediately move TVs, computers, and electronic equipment away from the leak area. Water and electricity are a dangerous combination. If water drips near a switch or light, turn off the main switch for that circuit and don't touch any wiring.

Step 3: Use Towels to Absorb Water

If water spreads, use old towels or cloths to absorb it. Place them around the leak area. Wet floors are a slip hazard, especially for elderly family members and children at home.

Step 4: Take Photos and Videos

Take photos and videos of the damage to:

Show the contractor (makes diagnosis easier)

Support an insurance claim (if you have coverage)

Photos of stained ceilings, damp walls, and drip points help a lot. With these photos, a roofing contractor can estimate the cause before arriving at your home — and give a more accurate quote.

Step 5: Contact a Contractor Immediately

Don't wait until tomorrow! Call a roofing contractor that handles emergency work. AtapPro operates 7 days a week including public holidays. Just WhatsApp photos of the damage — we reply with an estimate within 30 minutes.

What NOT to Do

Don't climb the roof while it's raining — extremely dangerous and slippery. Most roof repair accidents happen when homeowners climb up on wet surfaces.

Don't use electrical equipment near water — risk of electric shock.

Don't ignore small leaks — they only get bigger. Seeping water slowly damages roof trusses, electrical wiring, and ceiling plaster.

Don't rush a DIY patch — roof sealant applied on a wet surface won't stick. A bad patch job can even trap water somewhere else.

After the Rain Stops

Inspect the roof exterior from the ground (if safe) — look for shifted tiles, lifted zinc sheets, or peeling flashing

Take photos of visible damage

Call a contractor for a full inspection

Consider roof waterproofing for future prevention

Tips to Prevent Roof Leaks Before Monsoon Season

Prevention is cheaper than repair. Before November, run this quick inspection:

Clear roof gutters and downpipes of leaves and debris

Check roof screws — tighten loose ones, replace rusty ones

Look for rust spots or pinholes on zinc surfaces

Check for cracked, broken, or misaligned roof tiles

Watch for yellow stains on the ceiling — an early sign of leaking

Trim tree branches hanging over the roof

When Should You Call a Roofing Contractor?

Small jobs like clearing gutters can be DIY — provided the ladder is stable and the weather is dry. But for work on the roof itself, leave it to the experts. An experienced contractor knows how to walk on roof tiles without cracking more of them, and can trace the real source — not just patch the visible spot.

Call a professional if:

The leak involves more than one point

Water enters through wall joints or flashing

The roof is old with widespread rust

The ceiling is damp, sagging, or moldy
