and three (3) inches up the parapet wall above the cant. After the final roofing ply has been
applied to the top of the cant, prepare the surface area that is to receive flashing coverage
by torch heating granular surfaces or by application of asphalt primer; allowing primer to dry
thoroughly. Torch apply the metal foil-faced flashing into place using three (3) foot widths
(cut off the end of roll) always lapping the factory selvage edge. Stagger the laps of the
metal foil flashing layer from lap seams in the reinforcing layer. Extend the flashing sheet a
minimum of four (4) inches beyond the toe of the cant onto the prepared surface of the
finished roof and up the wall to the desired flashing height. Exert pressure on the flashing
sheet during application to ensure complete contact with the wall/roof surfaces, preventing
air pockets;this can be accomplished by using a damp sponge or shop rag. Check and seal
MODIFIED BITUMEN MEMBRANE ROOFING SYSTEM
07 52 19- 14
all loose laps and edges. Nail the top edge of the flashing on nine (9) inch centers. (See

through the field of the sheet to the vertical wood surface on 12 inch centers from the top of
the cant to top of wall curb, etc. Fully adhere the remainder of flashing reinforcing sheet that
extends over the cant and roof level. After the finish ply has been applied to the top of the
cant, prepare the surface area that is to receive flashing coverage by torch heating granular
surfaces or application of asphalt primer; allowing primer to dry thoroughly. Torch apply the
metal foil-faced flashing into place using three (3)foot widths (cut off the end of roll) always
lapping the factory selvage edge. Extend the flashing sheet a minimum of four (4) inches
beyond the toe of the cant onto the prepared surface of the finished roof and up the wall to
the desired flashing height. Exert pressure on the flashing sheet during application to
ensure complete contact with the wall/roof surfaces, preventing air pockets; this can be
