Expert Verdict — Reviewed by the SuperArbor Pro Desk
Counter flashing must always lap over the base flashing below it, so choose the 5 in. face when the exposed base flashing leg is taller than about 3 in. Cut the wall reglet cleanly and seal it fully to keep water out of the joint. Keep the mill finish for concealed work; for exposed transitions consider a painted alternative.
Cutting or grinding a reglet into masonry creates sharp metal edges and airborne dust — wear gloves, eye protection and a dust mask.
