Stop Water Damage Before It Starts
Malaysia’s heavy monsoon rains put flat roofs, balconies, and car porches at constant risk of water seepage. Unlike sloped roofs that naturally shed water, flat surfaces allow rainwater to pool and gradually penetrate through cracks, joints, and degraded surfaces.
At Roofing Man, we apply high-quality waterproof membranes and coatings to create a durable barrier against moisture -protecting your property from the inside out.
Our Waterproofing Solutions
Membrane Waterproofing
We apply torch-applied or self-adhesive bituminous membranes to flat roof surfaces. These create a physical barrier that prevents water penetration even under sustained pooling. Membranes are ideal for:
- Concrete slab flat roofs
- Large commercial roof areas
- Roofs with existing ponding issues
- Areas requiring long-term protection
Coating Waterproofing
Liquid-applied waterproof coatings are brushed or rolled directly onto the surface. They form a seamless, elastic layer that bridges hairline cracks and resists UV degradation. Best suited for:
- Balconies and terraces
- Car porches
- Small to medium flat roof sections
- Surfaces with complex shapes or obstacles
Ridge Capping & Flashing
The joints where roof planes meet -ridges, hips, and valleys -are among the most leak-prone areas. We reseal ridge capping cement and replace deteriorated flashing to prevent water from entering through these critical points.
The Waterproofing Process
Step 1: Inspection & Assessment
Our technician examines the entire surface, checking for cracks, pooling areas, membrane failures, and drainage problems. We identify all vulnerable points before recommending a solution.
Step 2: Surface Preparation
Proper preparation is essential for waterproofing to adhere correctly. We clean the surface, fill cracks, level uneven areas, and remove any loose material or old coatings that have failed.
Step 3: Application
Depending on the chosen method, we apply membranes or coatings in multiple layers, ensuring full coverage with no gaps. Joints, edges, and penetrations receive extra attention and reinforcement.
Step 4: Quality Assurance & Warranty
After curing, we inspect the completed waterproofing and conduct water testing where possible. Every waterproofing project comes with up to a 2-year warranty on workmanship and materials.

Why Waterproofing Is Essential in Malaysia
Malaysia receives an average of 2,500mm of rainfall annually, with the northeast monsoon bringing intense, prolonged downpours from October to March. This makes waterproofing not just recommended -it’s essential for:
- Preventing structural damage -water seepage weakens concrete and steel reinforcement over time
- Stopping mold and mildew -persistent moisture creates health hazards
- Protecting interiors -water stains, peeling paint, and damaged furnishings
- Maintaining property value -water damage significantly reduces resale value
