A ventilation baffle for use in building roofs includes a rectangular sheet dived by a plurality of fold lines into a rectangular central portion and a pair of side edge portions on opposite sides of the central portion. The edge portions are further divided into a pair of flange portions and a pair of spacer portions. The edge portions are bendable upward to form upstanding sides, the first pair of flange portions being bendable outwardly to form tabs which are attachable to the roof sheeting, said 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 an end portion which can be bent downwardly to define an outer end wall between adjacent roof rafters which can be further positioned to contact the top plate of the roof for attachment.

1. A ventilation baffle and stop 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 comprising a substantially rectangular sheet of stiff material having:opposite first and second ends and opposite first and second side edges, a first pair of longitudinally extending, parallel, fold lines respectively located close to the opposite side edges, said 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, 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, said first pair of elongated rectangular side edge portions being 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, said sheet also having 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 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.
