AbstractExamples have been given of the principles to follow in the design of roof flashings. It has been recommended that base flashings are to be kept free of items penetrating a roof; that metal counter flashings are to be separated from the roofing membrane; and that metal counter flashings are to shed water and be free to move at end joints to prevent buckling or breaking. The flashings, of course, cannot be divorced from the over-all design of the building wall and roof systems. The roof, for instance, must be sloped to provide drainage, and the walls designed to control rain penetration. Because of this, all details of the complete water control system should be worked out by the building designer.
