A roofing shingle and a method of manufacturing a roofing shingle wherein the bottom surface of said shingle is provided with a release coating of a continuous film of particles having poor interlaminar strength due to the particles having good to perfect basal cleavage. The release coating significantly eases separation of roofing shingles that stick together when stacked during storage and transit in warm environments.

L'invention concerne un bardeau de toiture et un procédé de fabrication d'un bardeau de toiture. La surface inférieure dudit bardeau est pourvue d'une revêtement amovible d'un film continu de particules à résistance au clivage faible en raison de la présence des particules possédant une bonne aptitude à effectuer un clivage de base parfait. Ce revêtement amovible permet de faciliter considérablement la séparation des bardeaux de toiture qui collent ensemble, quand ils sont empilés pendant le stockage et le transit dans des environnements chauds.
