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?
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.
