Signs your flat roof needs waterproofing
A concrete roof can look fine from the top while water is already moving through the slab. Look out for these signs, especially after a few heavy afternoon storms in a row.
- Water ponding for more than a day after rain
- Damp patches, efflorescence (white salt marks) or peeling paint on the ceiling below
- Cracks in the screed or old coating, or blisters and bubbles in an old membrane
- Gaps at the joint between the porch slab and the house wall
- Rust stains from exposed reinforcement bars, a sign water has been getting in for years
- Leaks around drains, aircond trunking or pipe penetrations through the slab
How we waterproof a concrete roof
Good waterproofing is mostly preparation. A new membrane laid over a wet, dusty or cracked surface will fail early, so our site team follows a fixed sequence.
- Inspect and test: check falls to the drain, ponding areas, cracks and the condition of any old coating
- Prepare: remove loose or failed material, clean the surface and let it dry
- Repair: fill cracks, correct low spots where practical, and treat corners and upstands
- Prime and apply the membrane, with extra reinforcement at drains, edges and penetrations
- Water test where possible, then hand over with photos and the 10-year warranty

How much does roof waterproofing cost in Malaysia?
Liquid or torch-on membrane waterproofing for flat concrete roofs, slabs and car porches costs about RM7 to RM9 per sq ft in 2026, with a 10-year warranty. A 250 sq ft car porch, for example, would fall roughly between RM1,750 and RM2,250. The exact price is confirmed after the free inspection based on preparation, access and roof condition.
What is the best waterproofing for a flat roof in Malaysia?
For most flat concrete roofs in Malaysia, a properly installed membrane system works best, either torch-on bitumen sheets or a liquid-applied membrane. Torch-on suits larger open roofs and porches, while liquid membrane suits complex shapes and many penetrations. The choice depends on the roof, so our technician recommends one after inspection.
How long does roof waterproofing last?
A well-prepared membrane system on a Malaysian flat roof is backed by our 10-year warranty. How long it lasts in practice depends on preparation, drainage and how the roof is used. Blocked drains, ponding and new holes drilled through the membrane are the main things that shorten its life, so simple maintenance helps a lot.
