Wooden Roof Ventilation Detail with French Tile and Timber Section

The wooden roof ventilation detail also includes tongue and groove wooden boarding approximately 3 by 4 inch thickness, forming part of the roof deck structure. A hydrophobic insulation layer is shown to protect the roof structure from moisture infiltration while maintaining ventilation beneath the roof covering. Additional components include a metal gutter channel for rainwater drainage and a fascia closing board that completes the roof edge structure. Timber rafters measuring approximately 2 by 4 inches support the roof structure and connect the roof assembly to the building wall.
