In a method of carrying out a fire-proofing treatment of rushes for thatching, the rushes for thatching are applied with a fire-retarding fluid, said fluid being applied by way of spraying or immersing onto the lowermost portion of the thatching material, typically 70 to 80 cm measured from the root. The treatment is carried out already during the cleaning and the processing of the thatching material and consequently before said thatching material is placed on the roof. The fireproof thatching material includes approximately 15% of water and can be placed on the roof immediately after the drying and the bundling. The method according to the invention is new and surprising by providing a thatching material which is fire-retarding on the portion of the stems facing the surroundings, and which is durable throughout the life of the entire roof. In addition, the costs of carrying out the fire-proofing by the method according to the invention are considerably lower than the costs involved in the hitherto known fire-proofing measures.
