The primary function of a roof base sheet is to act as a waterproof barrier. It prevents water penetration, reducing the risk of leaks that can lead to serious structural damage and costly repairs. Additionally, roof base sheets provide protection against various environmental elements such as wind, hail, and extreme temperatures. They also help in controlling heat transfer, contributing to the overall energy efficiency of the building.
