Roof Waterproofing Singapore
A leaking roof is more than an inconvenience left untreated, it leads to mould growth, damaged ceilings, and long-term structural harm. Our roof waterproofing Singapore service covers both landed properties and flat roof waterproofing common in HDB blocks and condominiums.
We use a combination of proven methods depending on your roof type:
- Torch-on waterproofing membrane – a highly durable, flexible membrane fused with heat, ideal for flat roofs and terraces
- Cementitious waterproofing – a cement-based coating that bonds directly to concrete, popular for both residential and commercial roofs
- Liquid-applied waterproofing membrane – seamless coverage for complex roof shapes and gutter areas
- Waterproofing paint and coating – an added protective, UV-resistant top layer that also improves the appearance of your roof
Every roof waterproofing membrane we install is matched to your roof’s material, slope, and exposure, so you get a solution built for Singapore’s climate not a one-size-fits-all fix.
Balcony Waterproofing Singapore
Balconies take a direct hit from rain and are one of the most common sources of leaks that travel down into the unit below a frequent and stressful issue between neighbours in HDB and condo living. Our balcony waterproofing Singapore service seals floor joints, drainage points, and wall-floor junctions to stop water infiltration at the source.If you’re dealing with a balcony water leaking to your downstairs neighbour, don’t wait the longer seepage continues, the more expensive the eventual repair (and the more strained the relationship). We diagnose the leak path first, then apply a membrane and waterproofing tape system engineered for outdoor, weather-exposed surfaces.
Bathrooms and toilets are the single most common spot for waterproofing failure in Singapore homes especially in older HDB flats where the original waterproofing membrane has simply reached the end of its life. Our bathroom waterproofing Singapore and toilet waterproofing Singapore services address the classic complaint we hear every week: “my toilet floor is leaking to the ceiling below.”
We apply cementitious waterproofing to floors, wall bases, and around pipe penetrations before any tiling begins. If you’re renovating, this step is non-negotiable waterproofing must always be done before tiling, never after, to avoid trapping moisture beneath the new floor.

Beyond roofs and wet areas, we also handle:
- Wall waterproofing Singapore – for damp walls, wall seepage, and rising damp in older buildings
- Ceiling waterproofing and ceiling leak repair – sealing the source of water seepage from the ceiling, not just patching the visible stain
- Basement waterproofing Singapore – protecting landed properties and commercial basements from groundwater intrusion
- Commercial and industrial waterproofing Singapore – tailored solutions for offices, F&B units, and MCST-managed condominium common areas

Why Choose a Professional Waterproofing Contractor
Waterproofing looks simple from the outside but fails quickly when done wrong. A reliable waterproofing specialist Singapore should offer:
- Experience – a proven track record across roof, balcony, bathroom, and basement projects
- Proper licensing and certification – compliance with Singapore’s building and safety standards
- A full range of services – so the same contractor who fixes your bathroom can also handle your roof or balcony later
- Warranty coverage – a written guarantee on materials and workmanship, not just a verbal promise
We combine all four, along with transparent, upfront quotes so you know the cost before we start, not after.
How much does waterproofing cost in Singapore?
Cost depends on the area, method, and current condition of the surface. Bathroom and toilet waterproofing typically costs less per job than full roof or balcony waterproofing due to smaller surface areas, while commercial projects are quoted based on square footage. We provide a free, itemised quote after an on-site assessment.
Why is my ceiling leaking when it rains?
This usually means the waterproofing membrane above on the roof or the floor of the unit above yours has cracked, degraded, or was never properly sealed at a joint. Rain finds the weak point and travels down through the concrete slab, surfacing as a ceiling stain or active drip.
Do I need to waterproof my bathroom before tiling?
Yes. Waterproofing must always be applied to the floor and lower walls before tiles go down. Tiling over an unwaterproofed or poorly waterproofed surface traps moisture, leading to leaks that are far more expensive to fix once the tiles are in place.
How long does roof waterproofing last?
A properly installed membrane, well-maintained, typically lasts several years before requiring recoating or reapplication though exact lifespan depends on the material used, roof exposure, and Singapore’s intense sun and rainfall cycle.
Who is responsible for waterproofing repairs in HDB flats?
Responsibility generally depends on where the leak originates and whether it affects a shared or private area this can be a source of dispute between neighbours. A professional inspection helps pinpoint the exact source, which is often the first step toward resolving liability
Can I waterproof my roof myself?
Small touch-ups with waterproofing paint or tape can help temporarily, similar to how a waterproof mattress protector guards against minor spills. However, full waterproofing especially membrane installation requires professional preparation, priming, and application to actually stop water infiltration long-term.
