The main roofing elements of a rondavel are spars or poles taken from tree limbs (called "gumpoles" these days), which have been harvested and cut to length. The roof covering is of thatch that is sewn to the poles with grass rope. The process of completing the thatch can take as little as one weekend or up to a year if made by a skilled artisan, as it must be sewn in one section at a time, starting from the bottom working towards the top. As each section is sewn, it may be weathered and aged to form a complete weatherproof seal.
