Defects, Repairs & Renovation
A landed house that leaks
Water leaks in a Malaysian landed house behave differently from strata inter-floor leaks. Rainwater tracks along trusses and beams before dripping into ceilings, making diagnosis tricky. In new HDA homes within the 24-month DLP, developers must repair within 30 days, while subsale buyers inherit the problem as-is.

What is actually happening here
This post works through why the wet patch is almost never directly under the hole, and what that means for a claim Most building problems in this climate come down to water and heat, and both travel a long way from where they get in before they show up as a stain you can see.
The physics of water tracking in a tropical roof space
In tropical Malaysian downpours, wind-driven rain penetrates under interlocking roof tiles, through fractured mortar ridges, or around compromised sheet metal flashing. Once water bypasses the outer roof skin, gravity does not pull it straight down onto the floor. Instead, surface tension causes rainwater to run along sloping timber rafters, steel trusses, and electrical conduits before transferring onto horizontal reinforced concrete tie-beams. The water continues its horizontal journey until it encounters a low spot or a ceiling screw penetration, where it pools and saturates the plasterboard ceiling. Consequently, the damp patch visible from your living room is routinely three to six metres away from the actual external defect.
The four primary penetration points: flashing, gutters, parapets, and window heads
Four specific architectural details account for the overwhelming majority of landed home leaks. First, valley gutters between roof pitches often suffer from inadequate width, poor gradient, or joint failure where debris causes stormwater to back up under tiles. Second, metal flashing at the abutment between a tiled roof and a party wall deteriorates or lacks proper step-chasing into brickwork. Third, parapet walls without adequate waterproof copings allow moisture to soak vertically downwards through porous brick masonry into second-floor bedroom walls. Fourth, window heads lacking functional drip grooves (drip lips) allow driving rain running down the external facade to track horizontally inwards above the window frame.
The 24-month DLP claim under Schedule G: formal notice and the 30-day rule
For new landed properties purchased from a licensed housing developer under Schedule G of the Housing Development regulations, the purchaser enjoys a statutory 24-month defect liability period calculated from the date of vacant possession. Under clause 26, the developer is legally obligated to rectify any defect in materials or workmanship within thirty (30) days of receiving written notification. Homeowners must submit dated photographs showing both the external roof defect and internal water staining, supported by a formal written demand. If the developer ignores the notice or sends workers who merely paint over the ceiling stain without addressing the roof flashing, the buyer retains the right to engage independent contractors and recover the cost.
Subsale landed homes and private renovation: who pays when warranties expire
When buying a subsale landed home, the legal landscape changes entirely. Malaysian contract law treats subsale transactions as 'as-is, where-is' purchases. There is no statutory defect liability period, no mandatory 30-day repair requirement, and no recourse against the vendor once completion takes place, unless the seller signed an explicit contractual warranty guaranteeing roof integrity. Similarly, if roof leaks arise following private renovation—such as installing solar panels, altering the car porch roof, or extending the kitchen—the dispute is strictly a private contract matter between the owner and the renovation contractor. The Tribunal for Homebuyer Claims has no jurisdiction over private contractor disputes.
Diagnostic protocol: methodical water testing before cosmetic repairs
Resolving a persistent landed house leak requires a rigorous diagnostic sequence before spending money on plasterboard replacement. An effective inspection begins with entering the attic void during a sunny morning to check for daylight penetration through tiles, followed by a controlled water hose test. A technician applies water to isolated roof sections starting from the lowest eaves, moving gradually upwards to valley gutters, side abutments, and finally ridge caps, allowing fifteen minutes at each location to monitor internal tracking. Only when the exact entry point is verified and sealed with proper metal flashing or liquid waterproofing should internal plasterboard and painting be replaced.
Check this against your own case
Get the defect documented before you argue about it. Dated photographs, a written notice to whoever is responsible, and proof they received it are worth more than any opinion about who is at fault. For anything structural, an engineer's report is the document that actually moves a dispute.
Buyer checklist
In a landed property, roof and wall leaks rarely originate directly above the damp patch on the ceiling. Rainwater penetrates defective flashing, cracked valley gutters, unsealed parapet wall copings, or window head joints, and travels horizontally along rafters, roof trusses, or concrete lintels before accumulating and dripping. Repeatedly plastering and repainting the wet ceiling mark fails because it ignores the actual entry point. Under Schedule G of the Housing Development regulations, a developer must rectify roof and wall defects within 30 days of receiving formal written notice during the 24-month defect liability period. On a subsale house, there is no statutory defect liability period; the property is sold as-is where-is, leaving repairs to the buyer.

Common questions
Why does my ceiling keep leaking even after my contractor patched and painted the wet stain?
Water runs horizontally along sloping rafters, trusses, and concrete beams before pooling at the lowest ceiling point. Patching the plasterboard only treats the collection point; unless the external flashing, roof tile, or gutter penetration is sealed, water will continue to track inside.
How long does a developer have to repair a roof leak in a newly completed landed house?
Under clause 26 of Schedule G, the developer is legally required to make good any defect in materials or workmanship within thirty (30) days of receiving formal written notification from the purchaser during the 24-month defect liability period.
Can I bring a roof leak claim against my renovation contractor to the Tribunal for Homebuyer Claims?
No. The Tribunal for Homebuyer Claims has jurisdiction strictly over claims by purchasers against licensed housing developers under Act 118. Disputes with private renovation contractors must be pursued through the civil courts or the Small Claims Court.
Does a seller have any legal obligation to fix roof leaks discovered after a subsale completion?
Under Malaysian law, a subsale property is sold strictly 'as-is, where-is' with no statutory defect liability period. The seller has no legal duty to rectify roof leaks discovered after signing, unless specific repair warranties were expressly written into the sale agreement.

What counts as a defect, and what is just wear, settlement or your own doing
The legal boundary between an actionable construction defect, natural settlement, fair wear and tear, and owner damage decides who pays for repairs in Malaysia. In statutory HDA homes within the 24-month defect liability period, developers bear rectification duties, whereas subsale properties are sold strictly as-is.
Lewis Conclusion
Before raising a dispute with a developer or seller, classify the issue against the statutory contract. If your property is a new HDA home within the 24-month DLP, serve a formal written defect notice demanding rectification within 30 days. If the developer fails to respond or perform, file a claim up to RM50,000 at the Tribunal for Homebuyer Claims within 12 months from the expiry of the defect liability period. If you bought a subsale unit, remember that no statutory defect period exists, meaning pre-signing inspection is your only legal protection.
Cracks in your walls: which are cosmetic, which are structural
Cracks in a Malaysian home range from superficial plaster shrinkage to structural foundation settlement. The orientation, pattern, and whether cracks widen over time determine whether you call a painter or a professional engineer. For HDA homes within the 24-month DLP, developers must make good within 30 days.
Lewis Conclusion
Never let a contractor persuade you to simply plaster over a diagonal or stepped crack that continues across structural elements. If cracks are active or accompanied by jamming doors, commission a registered professional engineer to carry out a structural assessment. If your house is within the statutory 24-month defect liability period under Schedule G or Schedule H, deliver a formal written notice compelling the developer to rectify within 30 days. If the developer defaults, bring your claim up to RM50,000 to the Tribunal for Homebuyer Claims within 12 months from the expiry of the defect liability period.
Damp and mould in a Malaysian house
Persistent damp and mould in a Malaysian house stem from three distinct mechanisms: external rain penetration, concealed plumbing leaks, and indoor condensation. Misidentifying the source leads to recurring mould outbreaks. Within the 24-month DLP, developers must make good within 30 days.
Lewis Conclusion
Stop repainting mouldy walls and establish the moisture source first by correlating the damp patch with rainfall, water meter activity, and air-conditioning usage. If your home is an HDA property within the 24-month defect liability period, serve a formal written notice under Schedule G or Schedule H demanding the developer locate and rectify the root cause within 30 days. If the developer fails to act, file a claim up to RM50,000 at the Tribunal for Homebuyer Claims within 12 months from the expiry of the defect liability period. For subsale homes, factor waterproofing upgrades into your purchase budget before signing.
