<p>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 (12) has a decking (14) and a sheet (16) overlying the decking. The sheet (16) has a plurality of projections (28) projecting upward away from the decking. The sloped roof has a vent slot (26) disposed along a roof ridge (20) adapted to permit air from an interior space under the roof to flow through the slot to the exterior. A strip (30) has a surface (44) shaped to match the projections (28) of the sheet. The strip has an air permeable and resilient portion. A ridge cap (24) overlies the slot (26) and the strip (30). The air permeable and resilient portion of the strip is adapted for the flow of vapors.</p> |
