ABSTRACT OF THE DISCLOSURE A roof expansion joint for bridging and closing an elongated opening in a roof and comprising spaced upright longitudinally extending members on either side of said opening, cants attached to said upright members and extending downwardly and outwardly therefrom to said roof, an outturned angular flange on one of said cants and a cover strip having a flange on one edge and an inturned flange on its other edge positioned on the other one of said cants and slidably engaged on said outturned angular flange, said inturned flange on the cover strip extending inunder said angular flange to form a movable weather tight seal across said elongated opening in said roof. This invention is distinguishable from other inventions by reason of the arrangement of the cover strip and its freedom of motion relative to the cant it slidably engages while maintaining a weather tight seal without the use of a flexible sealing member. - 2 -
