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.
Most jobs here are full system replacements on typical 700-900 sqft roofs. PU recoats remain popular, with premium torch-on bitumen and a 10-year warranty at the upper end. We scope each roof after a free site assessment.
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?
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.
