A ventilation baffle and stop is disclosed for use in buildings having walls made of wall studs, wall plates mounted on top of the wall studs, said wall plates having a top surface and a front surface facing away from an interior of the building, a plurality of spaced apart roof rafters mounted on top of the top surface of the wall plates, and roof sheathing mounted on top of the roof rafters. The ventilation baffle includes a substantially rectangular sheet of stiff material having opposite first and second ends and opposite first and second side edges. The sheet has a first pair of longitudinally extending, parallel, fold lines respectively located close to the opposite side edges of the sheet, said first pair of fold lines dividing the sheet into a rectangular central portion and a first pair of elongated rectangular side edge portions on opposite sides of said central portion. The sheet also includes a second pair of longitudinally extending, parallel, fold lines respectively located between and extending parallel to, the first fold lines and the opposite side edges, said second pair of fold lines dividing the first pair of elongated rectangular side edge portions into a first pair of flange portions positioned adjacent the side edges and a first pair of spacer portions positioned adjacent the central portion. The first pair of elongated rectangular side edge portions are bendable upward relative to the central portion to form upstanding sides, the first pair of flange portions being bendable outwardly relative to the central portion to form tabs positionable adjacent the opposing surfaces of a pair of adjacent roof rafters, said tabs being attachable to an inside surface of the roof sheeting mounted onto the roof rafters, said first pair of spacer portions separating the central portion of the sheet from the tabs and defining an air-flow passageway between the central portion and the roof sheeting. The sheet also has a transversely extending fold line located towards the first end and defining an outer rectangular end portion so that said rectangular end portion can be positioned adjacent to and -14- above the top plate and can be bent downwardly relative to the central portion to define an outer downwardly extending end wall between the opposing surfaces of a pair of adjacent roof rafters and extending downwardly from said central portion substantially into contact with said top plate, said end wall being attachable to the plate. -15-
