Counter flashing covers edge of rubber membrane Brown coat must be dead straight
Counter flashing covers edge of rubber membrane. 3/4" furring strip is used at top for a nailer for the coping. Flashing on the top of parapet walls or balconies is called coping,  or 3 sided flashing 

A gap is left between the membrane and the flashing for the flooring

Tarpaper, plaster stop and self-furring metal lath overlap edge of counter flashing. 

Rubber membrane is covered with a layer of plastic, then masonite, to prevent puncture. Mortar setting up and drying will even reduce the elasticity or the membrane. 
In other words it is better not to get any mortar on the membrane.

Bands are cut from metal lath and used to secure the lath to the top. Two layers of one by fours are nailed to form the bottom of the drip edge. Cap if filled with mortar. Note how the top is rounded from the center out for good water run off.
