The present invention relates to a composite shingle which comprises a hip, ridge or rake overlappable shingle of standard dimension bonded to a relatively rigid, randomly aligned fibrous, air permeable mat as an underlayer having a shorter length such that upon overlapping said shingles, the forward edge of the first shingle mat abuts the rear edge of the next shingle mat and provides a self-aligning, continuous vent area below the exposed surface of the installed shingles.
La présente invention concerne un élément de toiture composite comprenant un bardeau de dimension normalisée, à zone de chevauchement, destiné à un arêtier, à un faîtage et à un angle de pente, et sur lequel on a fixé un mat perméable à l'air, relativement rigide et à base de fibres alignées de manière aléatoire, en tant que sous-couche de longueur plus courte, de manière à ce que, lors du chevauchement desdits bardeaux, le bord antérieur du mat du premier bardeau vienne buter contre le bord arrière du mat du bardeau suivant et forme une zone d'aération continue, automatiquement alignée, sous la surface exposée des bardeaux installés.
