Roof Waterproofing in Thomson, Singapore
Thomson roof waterproofing splits between the older Upper Thomson cohort, where aging flat roofs need full strip-and-reinstall, and the newer Lentor and Springleaf clusters, where recent membranes are still well within service life. Current work therefore concentrates on the older belt.
Why Thomson
Roof Waterproofing for Thomson homes
Established Upper Thomson homes typically have modest flat roofs with original membranes well past service life, and full strip-and-reinstall is the usual scope. Some newer homes have rooftop terraces or accessible decks, where tile-over waterproofing requires more complex layered systems. PU coatings appear at the value end; torch-on bitumen with a 10-year warranty at the standard end.
Premium-standard scope range here. Standard flat-roof reinstall is the lighter end; rooftop terrace strip-and-reinstall is a larger scope. We scope each roof after a free site assessment.
On the older flat roofs along this corridor, treat the services penetrations as part of the waterproofing scope: air-con lines added over decades rarely came with proper detailing, and they are where new membranes get compromised first. Marine-grade flashings are cheap insurance while the roof is open.
Common Questions
Roof Waterproofing in Thomson: 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?
The right system depends on the existing roof, exposure, drainage, access and intended use. We compare complete assemblies, including preparation and details, rather than rank every acrylic, polyurethane or sheet product the same way. A trafficked or tiled roof needs a system specified for that finished build-up.
What is the difference between torch-on membrane and liquid membrane?
Torch-applied bituminous membranes use sheets with detailed seams and junctions. Liquid-applied systems form a membrane on the prepared substrate and can suit complex details. The exact product, application method, protection and inspection requirements determine suitability; the material category alone does not establish lifespan.
Can you fix a roof leak as an emergency?
We offer emergency leak response. The immediate action depends on safe access, weather and the source of the leak. Where a temporary repair is appropriate, we explain its limits and arrange investigation and permanent work when conditions permit.
What warranty do you offer for roof waterproofing?
The written proposal states the warranty available for the selected system and installation. Check the issuer, covered area, remedy, exclusions and maintenance duties, including what happens if later equipment work disturbs the roof. We explain those terms before you commit.
How long does roof waterproofing last?
Service life depends on the assembly, preparation, detailing, exposure, drainage and maintenance. We explain the selected system and its warranty terms, but do not use a single lifespan for every product in a material category.
