Malaysia is blessed with a fair amount of rain. When it rains, the water has a tendency to get into places where it’s not wanted, like the inside of your concrete roof structure, and corrode the structures from the inside out.
This will cause building structures, like the
car porch roof, to become brittle. Over time, it may come crashing down unexpectedly, causing harm to the vehicles parked below and any unsuspecting passerby.
