Roof Waterproofing in Frankel Estate, Singapore
Frankel Estate roofs are mostly 1970s and 1980s flat-slab construction with original membranes that have been patched repeatedly over the decades. Owners often arrive at the same conclusion most East Coast neighbourhoods reach: another patch will fail within 18 months, and a full strip-and-replace is the only durable answer.
Why Frankel Estate
Roof Waterproofing for Frankel Estate homes
Roof areas tend to be modest, typically 600–1,000 sqft, which keeps total project cost reasonable. Many of these homes also have small accessible rooftop areas used for laundry or services, where the membrane must support occasional foot traffic — that pushes the spec toward torch-on bitumen with a protective screed rather than thinner PU-only systems.
Value-pragmatic pricing, S$6,000–S$13,000 for full torch-on system replacement on a typical 700–900 sqft roof. PU recoats at the cheaper end remain popular where budgets are tight.
A detached home off Lucky Heights had its full 850 sqft flat roof stripped after the third recurring leak in 4 years. Torch-on bitumen reinstall with new flashings and improved drainage completed in 5 days.

Common Questions
Roof Waterproofing in Frankel Estate — 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.
