Roof Waterproofing Solutions in Singapore

Cost depends on the roof area, roof type, existing condition and the system specified. Torch-on membrane systems cost more than coatings but generally last longer. We provide a free inspection and fixed quotation.

A properly installed system typically lasts 5 to 10 years, depending on the material, UV exposure and whether a protection screed is applied. Regular inspection and prompt patching extend performance further.

Common causes are inadequate surface preparation, insufficient coating thickness, untreated cracks, or water entering from a different point such as a parapet joint or planter box. Correct diagnosis is essential.

Not always. If the existing membrane is well bonded and sound, we can often apply a new system over it. If it is blistered, delaminated or holding trapped moisture, removal is necessary for a lasting result.

A ponding test floods the roof with water for a set period to confirm the new waterproofing holds. We carry it out before handover and document the result as proof of performance.

Yes. Planter boxes, RC gutters, water features and podium decks are common leak sources in Singapore, and we waterproof all of them using suitable membrane systems.
