It is raining. The facade room is soaked in water. Can I find property compensation?

If the drainage is not smooth, resulting in rainwater backflow, then you can claim compensation.

If the house is low-lying and there is too much rain outside, so that there is too much water and the water overflows into the house, this is a natural disaster and it is force majeure. No one will compensate you. If you buy property insurance, the insurance company will compensate you. If there is no insurance, consider yourself unlucky.
