Protect Your Property with Professional Waterproofing
Water seepage is one of the most damaging problems a property can face. Whether you have a flat RC roof, a bathroom prone to leaks, or a balcony that lets water through, professional waterproofing is the long-term solution. At Roofing Man, we use advanced waterproofing systems designed to withstand Malaysia’s tropical climate.

Types of Waterproofing We Offer
Membrane Waterproofing
Membrane systems are ideal for flat RC roofs and large areas. We install high-quality membranes that create a continuous waterproof barrier:
- Torch-applied membranes - Durable bituminous membranes heat-fused to the surface
- Self-adhesive membranes - Clean application for sensitive areas
- PVC membranes - Long-lasting synthetic option for premium protection
Liquid-Applied Waterproofing
For complex shapes, small areas, or areas with many penetrations, liquid waterproofing provides excellent coverage:
- Polyurethane coatings - Flexible, seamless protection
- Acrylic coatings - Cost-effective solution for moderate exposure
- Cementitious coatings - Ideal for bathrooms and wet areas
Bathroom & Wet Area Waterproofing
Bathrooms are especially prone to water damage. We provide comprehensive bathroom waterproofing including:
- Floor and wall waterproofing
- Shower area treatment
- Toilet base sealing
- Balcony waterproofing

All our waterproofing work comes with up to 2 years warranty. If any issues arise within the warranty period, we return to address them at no additional cost.
Common Areas We Waterproof
Flat RC Roofs Many modern Malaysian homes and commercial buildings have flat concrete roofs that require waterproofing to prevent leaks.
Bathrooms & Toilets Wet areas need reliable waterproofing to prevent water seeping into walls and floors, causing damage to adjacent rooms.
Balconies & Terraces Outdoor tiled areas are exposed to rain and need proper waterproofing under the tiles.
Roof Extensions Added flat roof sections for car porches or extensions often need waterproofing treatment.
Commercial Buildings We handle commercial waterproofing projects of all sizes, from shop lots to office buildings.
