A building structure adapted to allow for ventilation of vapors from within the structure so as to retard deterioration of the structure. A sloped roof has a decking and a sheet overlying the decking. The sheet has a plurality of projects projecting upward away from the decking. The sloped roof has a vent slot disposed along a roof ridge adapted to permit air from an interior space under the roof to flow through the slot to the exterior. A strip has a surface shaped to match the projections of the sheet. The strip has an air permeable and resilient portion. A ridge cap overlies the slot and the strip. The air permeable and resilient portion of the strip is adapted for the flow of vapors.
