Roof repair on a landed home in Singapore costs about $150 to $1,500 for a small fix, and $12,000 or more for a whole new roof. For a terrace, semi-detached house or bungalow, the bill comes down to roof type, how far the damage has spread and how hard the roof is to reach. Proof-Tech repairs roofs on landed houses in Singapore, and our roof tile repair and restoration page covers the tile work we take on.
How much does house roof repair cost in Singapore in 2026?
A small repair costs $150 to $1,500, and a full roof costs $12,000 to $65,000, depending on the house and the roof. These are the prices we’d expect a fair quote to show this year, before GST, for work done properly.
| Job | Typical 2026 price (before GST) |
| Tile roof: replace a few cracked or slipped tiles and reseal the ridge | $450 to $1,200 per visit |
| Tile roof: restoration (clean, repoint the ridge, coat; tiles kept) | $25 to $60 per m² |
| Tile roof: strip and re-tile, with new underlay | $80 to $220 per m² |
| Metal roof: fix a leak at one spot (screws, washers, lap sealant, flashing) | $300 to $1,500 per spot |
| Metal roof: replace the roof sheets | $80 to $130 per m² |
| RC flat roof: patch one upturn or drain outlet | $150 to $600 |
| RC flat roof: re-waterproof the whole roof | $65 to $160 per m² |
| Scaffolding for a two-storey house | $2,500 to $6,000 |
Per square metre rates apply to the sloped roof surface, which is larger than the house’s floor plan. A quote worked out from the floor area comes in short, and the difference shows up later as an extra charge.
What does a tile roof cost to repair or re-tile?
Fixing a few cracked tiles is a one-visit job, and you are paying mostly for safe access and a roofer’s time, because the tiles themselves are cheap. On an older roof the tile profile may no longer be made. Then the roofer has to find a close match, or reuse sound tiles from a hidden part of the roof.
The ridge, the row of capping tiles along the top, is where leaks on tile roofs often start. When its mortar cracks, rain runs straight in under the capping. Resealing a short stretch fits inside a repair visit, but repointing the whole ridge belongs with a restoration.
Re-tiling a terrace roof usually comes to $18,000 to $35,000, and a bungalow $35,000 to $65,000, with a semi-detached house in between. Clay tiles sit at the top of the rate and concrete at the bottom. Pay for new underlay, the waterproof sheet under the tiles, when you re-tile. A worn-out underlay is often why a tile roof leaks in the first place.
Don’t pay for coating to stop a leak. Coating changes the tile surface, but water coming in through the ridge or a rotted underlay goes straight past it. Our guide to roof tile coating explains when coating is worth paying for.
How much does metal roof repair cost?
A leaking metal roof is usually a $300 to $1,500 job per leak. The fault tends to sit in the fixings while the sheets are still sound. The rubber washers under the screws perish in our sun, and each screw hole becomes a small leak.
The proper fix is new self-drilling screws, which drill their own hole and seal it with a fresh rubber washer. New sealant then goes on the laps where sheets overlap. A blob of sealant over an old screw costs less on the day, but it cracks in the heat and you pay for the same leak again.
Replace the sheets when rust has holed them, not when they look tired. If rust is limited to a few sheets near the gutter, replace those sheets alone. If it has spread across the roof, re-sheeting a terrace or semi-detached roof usually costs $12,000 to $22,000. A quote that includes new gutters will sit higher.
What is the roof leak repair price on an RC flat roof?
A leak traced to one spot on a flat concrete roof costs $150 to $600 as a patch repair. On a landed home the RC flat roof is usually the car porch, a back extension or a roof terrace. The leak tends to start at an upturn (the membrane turned up the wall) or a drain outlet.
Re-waterproofing a whole landed flat roof of 800 to 1,500 sq ft usually lands between $5,000 and $25,000. The spread comes from whether the old layer has to be stripped, which system goes down and whether a screed (a thin cement topping) goes over it. Our waterproofing cost guide breaks those systems down.
Pay to remove a failed membrane rather than laying a new one over it. A new layer over a wet one traps the water, and the leak comes back within a season or two.
Why does roof repair cost in Singapore vary so much between quotes?
Two quotes for the same roof can differ by half, and the gap usually sits in access, hidden damage and what is left out.
Access is the biggest swing. A small repair rarely needs full scaffolding, but a re-roof does. On a three-storey house, or a wall right beside the road where the scaffold needs a permit, scaffolding can reach about $12,000. A steep roof pitch, roughly above 35 degrees, adds another 15 to 25% for harness work.
Hidden damage shows up once tiles or sheets come off. Rotten timber battens (the strips the tiles hang on) or a rusted purlin under metal sheets add cost. A fair quote says upfront how that will be priced. A re-roof also carries $800 to $2,500 to cart away the old material.
Then check the tax. GST is 9%, and many roofing quotes are written before GST, so a $20,000 quote from a GST-registered contractor becomes $21,800.
Should you repair the roof or replace it?
Repair when the damage is in one area and the underlay, membrane or sheets around it are still sound. Replace when the roof itself is worn out, because then each repair moves the leak a few metres along.
These signs point to replacement:
- leaks in more than one room, or in several places at once
- the roof has been patched two or three times in a few years
- the underlay crumbles when a tile is lifted
- rust has holed metal sheets across the roof
- the flat roof membrane is brittle, blistered or lifting across open areas
Don’t let anyone sell you a $30,000 re-roof because of one cracked tile. And don’t keep paying $800 patches on a roof whose underlay has rotted, because three visits buy you a year and the ceiling damage keeps adding up.
To tell you which side your roof falls on, we need photos of the roof and any ceiling stains. Add your house type, number of storeys, roof type and when it was last worked on. With those we can say whether a repair will hold or the roof needs replacing. If water is already coming in, start with our roof leakage repair service.
What should a roof repair quote include?
A good quote lists each area of work with its own price, names the materials and says how the roof will be reached. It should state the roof type and area, and the tile, screw or membrane system being used. It should also say what happens to old material, whether GST is included and what the written warranty covers.
Treat these as red flags in a cheap quote:
- a lump sum with no scope, or “seal all cracks” as the whole job
- no line for scaffolding or access on a job that needs it
- a big job priced from photos, without a site inspection
- a price far below the other quotes you have
- full payment asked for upfront
Our 12 checks for choosing a contractor cover registration and warranty questions to ask before you sign.
Conclusion
Fix the roof locally if the damage is in one place. Budget for a full roof only when the underlay, sheets or membrane have failed across it. Get two or three itemised quotes and compare them line by line, including access and GST.
To confirm which applies to your house, we need roof photos, your house type and storeys, the roof type and the last work done. Send them through our enquiry form for a no-obligation quote, or call +65 6100 7558.
Frequently asked questions
Do I have to pay for a roof inspection?
Not always, so ask before anyone climbs up. Some contractors charge $150 to $350 for a landed roof inspection with a written report, and others fold the visit into the quote. Proof-Tech gives a no-obligation quote, and sending photos first helps decide whether a site inspection is needed.
Do I need approval to repair the roof of a conserved house?
Check with URA before you start. URA asks owners of conserved buildings to get the necessary approvals, such as Conservation Permission, before carrying out building works. Ask your contractor which approvals your roof works need, and build that waiting time into your plan.
How long does a roof repair take?
A small tile or screw repair is usually a day’s work once access is set up. A full re-roof takes longer, mostly because of scaffolding and weather, and rain days push it back during the monsoon. Ask for a programme in writing so you know when the roof will be open.
Should I repair the roof before the rainy season?
Yes, if you can. The Northeast Monsoon brings long wet spells from about December, which means a cracked tile or perished screw leaks more often and the work itself takes longer. A repair booked in the drier weeks is easier to schedule and finishes faster.
