 Metal base flashing is required on all vertical surfaces, walls, curbs, etc. when hot asphalt is used to adhere stripping (flashing) membranes.
-Metal base flashings are required on all walls and curbs on roof systems that utilize gravel ballast filter mats. Metal base flashings on protected and modified protected membrane roofs must “kick out” minimum 50 mm (2") over insulation and filter fabric. (see [[SBS Details:D1.7.2 Assemblies (Protected Membrane)|'''D1.7.2 Assemblies (Protected Membrane)''']]).

 Metal base flashing shall be kept approximately 25 mm (1") above gravel to prevent immersion in water with the exception of protected and modified protected roof systems.

 In the case of multi-wythe masonry, composite walls, or parapets, and where not restricted by seismic codes, continuous flexible thru-wall flashings must be supplied and installed (by others), at the next course above the reglet or, alternatively, the inside of the parapet wall must be completely flashed or cladded.
