Malaysian roofs face extreme conditions: scorching UV rays, heavy monsoon downpours, and constant humidity. Over time, even the best roofing materials deteriorate.
Common Causes of Roof Leaks
1. Cracked or broken tiles — thermal expansion causes cracks over years
2. Deteriorated waterproofing membrane — old membranes lose elasticity
3. Flashing failures — joints between roof and walls are weak points
4. Clogged gutters — water backs up and seeps under roofing
5. Concrete flat roof degradation — micro-cracks allow water penetration
