About the course

A flat mud roof symbolises simplicity and effectiveness in natural building roof techniques, and builders can construct it without using cement and steel bars. As a result, it represents one of the most straightforward methods in traditional roofing practices, both in India and globally. Its widespread popularity stems from its versatility and compatibility with locally sourced materials, promoting sustainable building practices.

The prevalence of flat mud roofs is widely apparent throughout India, manifesting in various locales from the southern state of Kerala to the northern territories of Himachal Pradesh and Ladakh. A flat mud roof construction involves utilising nearby resources to produce a flat roof surface, ensuring a sustainable and cost-effective solution. This roofing style serves as a weather-exposed roofing option and an intermediate or internal roofing solution, ideal for multi-story structures. Understanding the reasons for keeping a flat mud roof exposed or covered can be determined by examining the local climatic conditions. With its timeless quality and commitment to sustainable building practices, a flat mud roof is an excellent option for those looking to make a lasting impact on the environment.
