Roof Waterproofing in Namly, Singapore
Namly roof waterproofing work is dominated by rooftop terrace and rooftop pool projects on architect-designed homes. The roofscape on these properties is rarely a simple flat slab - it typically includes multiple levels, planter zones, water features, and outdoor entertainment areas, all requiring sophisticated multi-layer waterproofing.
Why Namly
Roof Waterproofing for Namly homes
Membrane systems are typically multi-layer torch-on bitumen with a separate protective layer below the tile deck, plus polyurethane composite around penetrations and movement joints. Rooftop pool waterproofing forms a specialised subset of the work, requiring drain, finish strip, membrane reinstall, and retile.
Top-of-band scope here. Rooftop pool waterproofing is a major project once full deck strip and reinstall is factored in. Premium 10-year warranty systems are universal. We scope each roof after a free site assessment.
A home off Namly Avenue had its 1,200 sqft rooftop entertainment deck stripped after a planter leak stained the master bedroom ceiling below. Full multi-layer membrane reinstall, replanting, and deck retile completed in 7 weeks.
Common Questions
Roof Waterproofing in Namly - FAQ
How much does waterproofing cost per square foot in Singapore?
The cost depends on the system chosen - PU coatings, torch-on membranes, and cementitious systems with fabric reinforcement each carry different rates - as well as the roof area and the surface condition. We provide a tailored quote after a free roof inspection.
What is the best waterproofing method for a flat roof?
For Singapore flat roofs, torch-on modified bitumen membranes offer the best balance of durability and cost. They last 10-15 years and handle our UV and rainfall conditions well. For roofs with heavy foot traffic, cementitious waterproofing with a protective screed is preferred.
What is the difference between torch-on membrane and liquid membrane?
Torch-on membranes are pre-formed sheets heat-welded to the surface - very durable (10-15 years) but require skilled application. Liquid membranes (PU coatings) are painted on, easier to apply around complex shapes, but last 5-8 years. We recommend torch-on for large flat areas and liquid for detailed work.
Can you fix a roof leak as an emergency?
Yes. We offer emergency leak response for active roof leaks. Temporary waterproof patches can be applied within 24-48 hours to stop immediate damage, followed by a permanent repair scheduled when weather permits.
What warranty do you offer for roof waterproofing?
Our premium torch-on membrane systems come with a 10-year material and workmanship warranty. PU coating systems carry a 5-year warranty. All warranties cover both materials and labour for any leak that develops in the treated area.
How long does roof waterproofing last?
Quality membrane systems last 10-15 years. Polyurethane coatings typically last 5-8 years before recoating is needed.
