- surface.
- 2. Install continuous metal flashing to extend 3 inches
- (76 mm) up vertical surface.
- 3. At locations where vertical surface will abut top
- edge of tile, install metal flashing to extend 3
- inches (76 mm) up vertical surface, form metal
- flashing to extend minimum 3 inches (76 mm) over
- tile, and form 1/2 inch (12 mm) return hem at edge of
- metal.
