Heavy rain and leaking roof

[pucman]

These few days there is heavy rain and my roof is leaking at new places ! :(

If it is mild to medium rain, then it won't leak.

Do you guys experience the same problem in your double-storey terrace house ?

Is there any real solution to this ?

Some of your tiles are probably blown out of position. During strong wind/rain conditions, water backflow is possible if there is insufficient tile overlap.
Get a roofer to reset the tiles. He might even find a few cracks that causes leaks during heavy downpours.
Hope it helps.
