Terrace houses have unique roofing problems. Learn about roof types, common issues, and best solutions.
Terrace House Roofing — A Complete Guide
Terrace houses are the most popular house type in Malaysia. But terrace house roofs come with their own challenges because the units are physically connected to the neighbours. When one section fails, the damage can spread to the unit next door.
This guide covers terrace house roof types, the most common problems, repair cost estimates, and maintenance tips to make your roof last longer.
Why Terrace House Roofs Are Different
Unlike bungalows or semi-Ds, terrace houses share walls with their neighbours. That shared structure directly affects the roof:
Party wall — the roof joint between two units is the weakest point. Roof flashing here lifts or cracks easily.
Rear extension — most terrace houses have a kitchen or extra room with a zinc roof, installed separately from the original roof.
Corner lot units — more exposed to wind and rain because there is no sheltering unit on one side.
Limited access — repair work sometimes needs a path across the neighbour's roof section.
That is why a roofing contractor familiar with terrace houses can pinpoint the root cause faster.
Terrace House Roof Types
1. Clay Roof Tiles
The most traditional in Malaysia
Lasts 25-40 years
Heavy but weather-resistant
2. Concrete Roof Tiles
Popular for modern terrace houses
Lasts 30-50 years
Available in many colours
3. Zinc Roof (rear / extension sections)
Cheap and quick to install
Lasts 10-15 years
Common for kitchen extensions
4. Metal Deck (upgrade option)
A modern replacement for old zinc
Thicker sheets, quieter in heavy rain
Suitable for awnings and rear roofs
Common Terrace House Roof Problems
1. Leaks at the House Joint
The most common leak spot is the joint between two units (the party wall). Water seeps through flashing that has loosened, cracked, or rusted. Water stains usually appear along the top of the side wall, not in the middle of the house.
2. Rear Roof Leaks
The zinc roof at the back (kitchen/added bathroom) leaks frequently because:
Zinc rusts with age
The slope is insufficient, so water ponds
Gutters get blocked by leaves and debris
Roof screws loosen or their rubber seals perish
3. Broken Tiles
Terrace houses aged 20+ years often have broken roof tiles, especially exposed corner lot units. Even a single broken tile can channel water straight into the ceiling.
4. Drainage Problems
Water that does not flow properly ponds on the roof. A blocked roof gutter makes things worse, especially during the rainy season.
Simple Checks Before Calling a Contractor
Do a basic inspection first so you can describe the problem clearly:
Check the ceiling — look for yellow stains, water marks, or bubbling paint
Inspect from outside with your phone camera — look for broken tiles or lifted zinc
Look at the roof ridge — cracked ridge mortar is a common leak source
Check the roof gutter and downpipes — make sure nothing is blocked
Photograph every defect as a reference when requesting a quotation
Avoid climbing the roof yourself. Tiles crack easily underfoot and the risk of falling is high.

Terrace House Roof Maintenance Tips
Inspect the roof twice a year — before and after the monsoon season
Clean gutters and valleys every 3 months
Trim tree branches growing too close to the roof
Never let anyone step on tiles without walking boards
Repaint zinc roofs every 5 years to prevent rust
After a heavy storm, re-check the ridge and flashing
When to Call a Roofing Contractor
Some problems can wait, others cannot. Contact a contractor immediately if:
Water drips into the house every time it rains
Ceiling water stains grow larger week by week
More than a few tiles are broken at once
The rear zinc roof is badly rusted or sagging
The ceiling starts to sag or smells damp
A leak left alone will damage the roof trusses, electrical wiring, and ceiling. The eventual repair bill is far higher than an early fix that starts from just RM150.

Why do terrace house roofs often leak at the joint with the neighbour's house?
The joint between two units (the party wall) relies on roof flashing to keep water out. Once the flashing loosens, cracks, or rusts, rainwater seeps in through the gap. Replacing the flashing typically costs around RM200-500, with additional sealant at RM100-300 — far cheaper than repairing a ceiling damaged by leaks.
Only a few roof tiles are broken — do I need to replace the whole roof?
No. Broken tiles can be replaced piece by piece at RM5-15 per piece, and tile repair works usually fall within RM200-800. A full roof replacement is only needed when the damage is too widespread — for a terrace house, the estimate is around RM3,000-8,000.
The rear zinc roof of my terrace house keeps leaking — should I repair it or switch to metal deck?
If the zinc only leaks in one or two spots and is still solid, a minor repair starting from RM150 is enough. But if the zinc is badly rusted or sagging, a full replacement is cheaper in the long run — either new zinc or an upgrade to metal deck at RM18-35 per sq ft, which lasts longer. The contractor will assess the actual condition during a site inspection.
Should I inform my neighbour before starting terrace house roof repair work?
Highly recommended. Terrace house roofs connect at the party wall, so work at the joint may involve flashing shared by both units, and the contractor sometimes needs access from the neighbour's side. Informing them early avoids misunderstandings — an experienced roofing contractor will handle the joint section with care.
