Designers sometimes eliminate the stone cap overhang and drip to give the wall a clean, smooth, contemporary appeal. While this is not an ideal condition, there are approaches that protect the wall.
In Figure A, the detail is a flush cap with drip. Remember, the wall will vary in thickness based on acceptable construction tolerance, and lips can form on the top of the wall. Metal flashing with a drip edge is required to protect the wall. This flashing should be sealed and adhered to the wall below. Figure B illustrates a flush cap with no drip edge on the flashing. While designers will sometimes employ these details, remember they are not as effective as flashing with drips and caps with overhangs.
