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 pricing, S$25,000–S$60,000+. Rooftop pool waterproofing routinely exceeds S$45,000 once full deck strip and reinstall is factored. Premium 10-year warranty systems are universal.
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?
Waterproofing costs $8–$25 per square foot depending on the system. Basic PU coating runs $8–$12/sqft. Torch-on membrane systems cost $15–$20/sqft. Premium cementitious systems with fabric reinforcement run $20–$25/sqft. Total project costs typically range from $5,000 to $25,000.
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.
