-:When the height of the ''control joint'' exceeds 203.2 mm (8”) (Ref. Drawing (A)), no fewer than two plies of sheet membrane flashing shall be carried up at least 203.2 mm above the ''finished roof system surface''.
+:Two models are illustrated here.  A ''control joint'' may be as low as 101.6 mm (4”), shown in '''Drawing B''', provided it is not capped with a ''linear metal flashing''.  If a metal cap flashing is specified, the minimum height of the ''control joint'' must be 127 mm (5”), shown in '''Drawing A''', and screw fasteners securing the cap flashing must be kept at least 88.9 mm (3-1/2”) above the ''finished roof system surface''.
 ;(3) [[SBS Roof Systems Standard#PART_13|'''Metal Cap Flashing''']]:
-:Required only when the low ''control joint'' (less than 203.2 mm (8”) in height) is not fully enveloped with at least two plies of sheet membrane flashing.  Cap flashing must be designed and installed as required in [[SBS_Roof_Systems_Standard#PART_13 | Part 13]].
+:Cap flashing may be employed for protection of the waterproofing, and must be designed and installed as required in [[SBS Roof Systems Standard#PART_13 | Part 13]].
 :Note that the cap flashing is sloped at least 2% (mono slope illustrated) when the width of the flashing exceeds 101.6 mm (4”) (Ref. [[SBS_Roof_Systems_Standard#13.1.3.6. Cap Flashing, Counter-flashing, and Reglet Flashing | Article 13.1.3.6., “Cap Flashing, Counter-flashing, and Reglet Flashing”]]).
