Abstract

Corner flashing for the roof line at intersections of the roof surfaces with upstanding walls or projections such as dormers, chimneys, and the like is provided to fit, without cutting, the roof line of widely varying inclinations and embrace the corners of the projections above the roof line without opening a possible leakage path. The flashing is preferably a molded one-piece plastics material member with a base for seating on the roof deck and underlying the roofing material to radiate from the corner of an upstanding projection above the roof line and having integral upstanding substantially right angle sides for abutting the area on both sides of the projection and with the corner of the sides being foldable to form a tuck overlying one of the sides to pull both sides into tight abutting engagement with the projection. The tuck may overlap either side of the upstanding side and be secured to the upstanding projection by a nail or the like. The resulting tucked configuration seals a corner of the projection without opening any leakage path.
