ABSTRACT:
A roof flashing unit which is attachable to a parapet or other upstanding wall at its intersection with a roof to ensure a tight, waterproof roof construction. The unit includes a rectangular sheet of bendable metal having a transverse Z-shaped bend therein to define an upper or counter section which is secured to the wall and a larger base section. The diagonal of the Z bend forms with the counter section are open-ended channel, and it forms with the base section an open-ended pocket. Wedged into the pocket is the upper edge of a flexible waterproof membrane which overlies the base section. To arrange the flashing units in an overlapping series, the fold line between the diagonal and base sections at the end of one unit in the series is slit to permit telescoping of the channel of the adjacent unit into the channel of the one unit, the base section of the adjacent unit overlapping the base section of the one unit and the membrane of the adjacent unit overlapping the membrane of the one unit, whereby the membranes are shingled.
