The Khiru Roof is an ancient and authentic technique for constructing flat roofs, hailing from the region of Rajasthan. This dry region roofing system methodology uses readily available materials from the surrounding environment, such as bamboo, rural wood, and other natural resources. The roofer first assembles a fundamental roof structure using materials such as bamboo, rural wood, and other natural resources. Then, they add layers of indigenous vegetation, including stems, branches, and leaves, to secure the mud and lime filling and ensure the stability and longevity of the roof.

This indigenous approach to construction is adaptable to various locations and climates, as it can be adjusted to incorporate local materials. It is a misconception that the materials must come solely from Rajasthan, as the Khiru Roof aims to promote sustainability and affordability by utilizing resources from the immediate vicinity.

Reviving this method is twofold: to preserve a traditional aspect of Rajasthani culture and offer a roofing solution with high thermal insulation properties. To achieve this, the Thannal founders and master artisans have collaborated and made necessary modifications to the Khiru Roof method, ensuring its viability in the modern era. In addition, the involvement of seasoned artisans and the next generation of roofers further enriched this process.
