Always extend the membrane up the wall a minimum of twelve inches (12"). When using wood shakes, or other siding materials, a Termination Bar is not required if the siding material is brought down at least eight inches (8") below the top of the EPDM sheet. All siding must be kept a minimum of four inches (4") above the roof deck.
Determine the height of the finished wall flashing (12" height or less if job conditions won't allow for full 12") and the placement of the aluminum RUBBERALL® Termination Bar. Chalk a line at this level. Peel the top of the wall flashing from the wall to chalk line and apply a heavy bead of Water Cut-Off Mastic between the EPDM and wall. The mastic should be applied so that the final position of the Termination Bar will be directly over the Water Cut-Off Mastic.
Fasten the Termination Bar with nylon/metal anchor pins, or aluminum sheet metal screws. Install a fastener in every pre-drilled hole. Remove excess membrane that extends above the Termination Bar and apply Lap Caulk to the top of the Bar.
Termination bar comes in five foot (5') and ten foot (10') lengths.
