Seepwise arranges roof leak repair for landed homes in Singapore when water is already coming through. HDB roofs are maintained by the Town Council and condo roofs by the MCST, so if you live in either, contact them first (HDB).
What happens on the first visit
The specialist traces the leak from the inside stain back to the roof: outlets that overflow during heavy rain, cracked flashings, failed laps on metal sheets, slipped tiles, or cracks in a flat slab. Where safe, a controlled water test on suspected areas confirms the entry point before repair.
What to do while it is raining
Move valuables and electrical items away from the drip, put a bucket under it, and lay towels to stop water spreading across the floor. If water is near light fittings or switches, switch off that circuit at the distribution board and keep clear. Photograph the stain and the time: the pattern helps the specialist.
Do not go onto a wet roof. Most roof falls happen to homeowners checking a leak during or right after rain.
Where roof leaks usually enter
- Blocked outlets and gutters that overflow in a downpour and push water under membranes
- Flashings where the roof meets a parapet or wall
- Laps and screw holes on metal roofs
- Cracked or slipped tiles, ridges and valleys on pitched roofs
- Cracks and failed membrane on flat concrete roofs
A leak inside rarely sits directly under its entry point; water travels along the slab or the underside of tiles before it drips.
Repair now, waterproof properly later
A roof leak repair fixes the entry point found. If the inspection shows the membrane is failing across the roof, you get two options in writing: the targeted repair now, and a full roof waterproofing scope to plan before the wettest months, December to early January (World Bank).
What is included
- Leak traced from the stain to the roof
- Outlets and gutters cleared
- Controlled water test where safe
- Targeted repair of the entry point
- Interior made good after the source is fixed
- Photos before and after
- Written note if a full re-waterproof is needed
- Advice on whether insurance is worth notifying
Painting over it vs a quick fix vs a proper repair
| DIY | Quick fix | Proper repair | |
|---|---|---|---|
| Response | Bucket and hope | Sealant where it drips | Entry point traced on the roof |
| Outlets checked | No | No | Cleared and tested |
| Confirms the fix | Next storm | Next storm | Controlled water test |
| Bigger picture | None | None | Written full-roof assessment |
| Safety | Wet-roof risk | Varies | Specialist access |
What it costs
Roof leak repairs are priced after the entry point is found; a targeted fix and a full re-waterproof are quoted separately.
