Roof Waterproofing in Serangoon Gardens, Singapore
Serangoon Gardens roofs are mostly older flat-slab construction whose original membranes have taken decades 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
By the time owners here call for a proper system replacement, the roof has usually been patched several times already. Another patch tends to buy months, not years, because the failure is in the membrane as a whole rather than at any one spot. Roof areas on these homes are modest, which keeps a full strip-and-replace within reach.
Typical jobs here are full torch-on or PU coating systems on modest terrace-scale roofs. PU coatings are common where budgets are constrained, with the understanding that they need recoating sooner than a full membrane system. We scope each roof after a free site assessment.
A roof that has leaked repeatedly despite several patches is telling you the membrane is done. The useful survey walks the whole slab, checks the parapet junctions and every penetration, and looks at whether the original outlets still cope with heavy monsoon bursts, because undersized drainage will find the next weak point in any new membrane.
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 to 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. They are very durable (10 to 15 years) but require skilled application. Liquid membranes (PU coatings) are painted on, easier to apply around complex shapes, but last 5 to 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. We apply a temporary waterproof patch as quickly as the weather allows to stop immediate damage, then schedule the permanent repair once conditions permit.
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 to 15 years. Polyurethane coatings typically last 5 to 8 years before recoating is needed.
