Question

Most of the houses in Punjab have flat roofs, while most of the houses in Kerala have sloping roofs . Can you say why this is so ?

Answer 1

The rate of rainfall is very low in Punjab and this is the reason why they have flat roofs so that they can collect the rain water from time to time and use it for irrigation purpose. The flat roofs in Punjab help in generating the heat also.

The slating roofs are necessary in Kerala because due to heavy rainfall, water can be stored on the roof, and people in Kerala need to design their roof with proper slopes to prevent water damage.
