Roof Waterproofing in Serangoon Gardens, Singapore
Serangoon Gardens roofs are mostly 1980s vintage flat-slab construction with original membranes that have now had 35+ years of monsoon and UV exposure. Leaks are common, particularly at the slab-to-parapet junction and around aging penetrations for old hot-water service lines and air-con pipework.
Why Serangoon Gardens
Roof Waterproofing for Serangoon Gardens homes
Most owners here have already patched their roofs multiple times over the years before calling us for a proper system replacement. Our first job is usually convincing the owner that another patch will fail within 12-18 months and that a full membrane strip-and-replace is the right move. Roof areas are modest, typically 600-1,000 sqft, which keeps total project cost reasonable.
Most jobs here are full torch-on or PU coating systems on typical 700-900 sqft roofs. PU coatings are common where budgets are constrained, with the understanding that the system will need recoating in 6-8 years. We scope each roof after a free site assessment.
A terrace off Lichfield Road had its 800 sqft flat roof stripped after the fourth recurring leak in 5 years. Full torch-on bitumen reinstall with new flashings and an additional drainage outlet ran 4 days on-site.
Common Questions
Roof Waterproofing in Serangoon Gardens - 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.
