| 1. A building structure adapted to allow for ventilation of vapors from within the structure to an exterior area so as to retard deterioration of the structure, comprising: a sloped roof having a decking and a contoured metal roofing sheet overlying the decking;
the sheet having a plurality of projections projecting upward away from the decking;
the sloped roof having a vent slot disposed along a roof ridge adapted to permit air from an interior space under the roof to flow through the slot and to the exterior;
a strip having a surface including a plurality of recesses shaped to match the projections of the sheet, the surface of the strip engaging the sheet continuously between the projections with the recesses engaging over the projections, the strip having an air permeable and resilient portion that is located at least in part between the projections of the sheet that is a barrier against wind driven rain; and
a ridge cap overlying the slot and the strip, wherein the air permeable and resilient portion of the strip is adapted to allow the flow of vapors from within the structure to an exterior area and to prevent ingress of water, dirt and insects into the building structure.
