Flat Roof Waterproofing: Common Issues and Perfect Solutions
Flat roofs are widely used in modern homes and commercial buildings because of their design appeal and usable space. However, flat roofs require extra care when it comes to handling rainwater. Unlike sloped roofs, flat roofs hold water for longer durations, increasing the chances of leakage and structural damage if waterproofing is not done properly.
For buildings in rainy regions like Kerala, choosing the right waterproofing method is crucial to protect the structure from long-term moisture damage. If you’re searching for trusted Roof waterproofing in Kerala, Midas Waterproofing provides professional and advanced roof protection solutions designed for the tropical climate.
Common Flat Roof Problems
1. Standing Water or Water Ponding
Flat roofs do not naturally drain water. If not waterproofed correctly, water collects in uneven spots and remains on the terrace for hours or even days, leading to:
- Weakening of concrete
- Dampness
- Leakage over time
2. Cracks on the Roof Surface
Changes in temperature cause expansion and contraction on the roof surface. Over time, this results in cracks, allowing water to seep into the slab and interior walls.
3. Improper Drainage Design
Blocked outlets or poorly designed drainage systems are major contributors to roof dampness. Even a small blockage can cause severe pooling issues.
4. Damaged or Worn-Out Waterproofing Layer
Old or low-quality waterproofing layers lose flexibility and peel off, especially under continuous rain and heat.
Best Waterproofing Solutions for Flat Roofs
Midas Waterproofing, through advanced systems and skilled professionals, offers long-lasting solutions rather than temporary fixes. Here are some of the most effective treatments:
1. Liquid-Applied Membrane
A seamless, elastic waterproof membrane is applied over the surface. Once dry, it becomes a flexible shield preventing water penetration.
Best for: Homes & commercial roofs
Advantages: Crack-bridging ability, UV-resistant, durable finish
2. APP / Bitumen Membrane (Torch Applied)
A thick membrane sheet is heated and fused to the roof surface, forming a strong protective layer.
Best for: Large buildings and industrial flat roofs
Advantages: Withstands extreme rain, long lifespan, durable
3. PU (Polyurethane) Coating
Polyurethane provides excellent waterproofing performance, especially on roofs that experience continuous water stagnation.
Best for: Roofs with ponding water issues
Advantages: Highly elastic, superior sealing properties
4. Cementitious Waterproofing
This involves applying a cement-based waterproof coating to strengthen the structure.
Best for: New construction & renovation projects
Advantages: Strong bonding, moisture resistance
Why Flat Roof Waterproofing Is Vital in Kerala
Kerala experiences heavy monsoon rainfall and constant humidity — both of which make roofs highly prone to water seepage. Investing in Roof waterproofing in Kerala can prevent:

- Damage to interiors and electrical wiring
- Costly future repair work
Waterproofing ensures structural safety and extends the lifespan of the building.
