What is the purpose of steep roofs on southeast Asia longhouses?

Steep roofs on Southeast Asian longhouses serve multiple purposes, primarily related to climate and practical needs. The steep pitch facilitates water runoff during heavy monsoon rains, preventing water accumulation and potential structural damage. Additionally, this design helps to keep the interior cooler by allowing hot air to rise and escape, promoting ventilation in the humid tropical environment. The roofs also provide ample space for storage and can enhance the aesthetic appeal of the longhouse.
