Roof Waterproofing in Seletar Hills, Singapore
Seletar Hills roofs are predominantly 1970s and 1980s flat-slab construction with original membranes that have been patched repeatedly. Persistent ceiling staining on the upper floor is the typical trigger for owners to engage us for proper full-system replacement.
Why Seletar Hills
Roof Waterproofing for Seletar Hills homes
Roof areas tend to be modest, 600–1,000 sqft, keeping total project cost manageable. PU coatings remain a popular budget-tier option for owners not ready for full membrane spend. Premium torch-on systems are increasingly chosen by second-generation owners who want a longer warranty period and fewer recurring maintenance cycles.
Value-pragmatic pricing, S$5,000–S$11,000 for most full system replacements on typical 700–900 sqft roofs. PU recoats at S$5,000–S$8,000 remain popular. Premium torch-on bitumen with 10-year warranty runs S$8,000–S$12,000.
A detached home off Jalan Mempurong had its 800 sqft flat roof stripped after the fourth recurring leak in 5 years. Torch-on bitumen reinstall with new flashings and improved drainage completed in 5 days.

Common Questions
Roof Waterproofing in Seletar Hills — 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.
