A building structure (10) adapted to allow for ventilation of vapors from within the structure (10) so as to retard deterioration of the structure (10). The building structure (10) has a roof (19) extending over one or more vertical side walls (26). An attic space (40) is enclosed between the roof (19) and an internal ceiling (38). The roof (19) is constructed on a plurality of parallel rafters (20). The rafters (20) are supported by a top plate (16) capping each vertical side wall (26). The roof (19) has a roof sheathing member (42) overlying the roof rafters (20). A fascia (50) is secured to the outer ends of the rafters (20). An air permeable and resilient strip (52) is interposed between the fascia (50) and the outer ends of the rafters (20) to provide for the flow of vapor therebetween and into the attic (40).
