Why Roof Waterproofing Matters in Singapore
Intense tropical downpours, strong UV, and thermal expansion make roofs here prone to cracks, failed joints, and membrane wear. Left untreated, seepage leads to ceiling stains, mould, damaged insulation, and escalating repair costs. Professional roof waterproofing services prevents water ingress, extends roof life, and safeguards interiors, whether you manage a landed property, factory, or commercial site.

Our Roof Waterproofing Services
We don’t push a “one-size-fits-all”. We recommend what suits your roof, budget, and maintenance plan.
Liquid-applied membranes (PU/Hybrid/Polyurea/Acrylic)
Seamless, ideal for complex details on RC/ flat roofs and gutters. Good crack-bridging and refurb cycles.
Bituminous (Torch-on/ Self-adhesive) sheets
Proven durability on flat roofs; requires experienced installers for laps/ upturns
EPDM/ TPO single-ply
Excellent UV resistance and service life; suited to large RC roofs and some metal roof retrofits.
Metal roof elastomeric systems
Corrosion treatment + high-elongation topcoats that seal around screws, seams, skylights; reduces future maintenance.
Tile roof sealing & detailing
Replace broken tiles, re-bed/ re-point ridges, treat valleys and flashings, then apply breathable protective coatings.
What Customers Says
Flat vs Metal vs Tile
While we assess each roof to identify the best waterproofing solutions. Here is a general guideline of suitable approaches for each roof types.
RC flat roofs: best with liquid-applied or bituminous membranes after crack repairs and proper terminations.
Metal roofs: address rust and fasteners first; use corrosion-inhibiting primers + elastic coatings that handle thermal movement.
Tiled roofs: repair substrate, valleys, and flashings; seal ridges and apply protective coats while maintaining breathability.
Our Roof Waterproofing Cost
As waterproofing is a labour-intensive professional service, costs depend on roof size/ access, prep work (rust treatment, re-screwing, tile repairs), and system specified. Pricing is typically calculated per square metre with larger areas costing less per m² due to economies of scale. As a trusted waterproofing contractor, we will always perform an on-site survey to give you an accurate quote.
What to expect during a project
Timeline
Most residential roofs complete in days, larger sites in phases. We will advise and state timeline clearly in all our proposals
Access
It will be great to have your building roof access plan ready. Don’t worry if you do not have it, we will plan safe access, scaffolds or rope access as needed.
Weather
Roof waterproofing application can only be done on dry weather. We monitor forecasts and schedule membrane works on dry days.
Aftercare
Simple maintenance keeps membranes performing longer; we’ll show you how.
