The main building of the Alpage de Ritort has two adjoining parts with two different roofs. There is no lauze here. Traditionally it was the ancelles (split wood tiles) that were used, some lauze was then used underneath to prevent the wind from ripping them off. In Ritort, the lower part of the building, used as a cheese dairy, has a tin roof that was restored in 1997, which is identical to the pre-existing roof. As for the adjoining dwelling, it has a traditional mixed ancelle-lauze roof.
