Coordinate permitting and flashing for a masonry parapet rebuild

Steps

1. Confirm scope: rebuilding a parapet above the roof line typically triggers a building permit as exterior wall/structural work under the locally adopted building code, even on a repair-in-kind project.
2. Coordinate the parapet cap flashing/coping and roof membrane tie-in with the roofing contractor before masonry demolition begins, since sequencing errors here are a leading cause of new leaks.
3. Verify parapet height, coping slope/overhang, and through-wall flashing details against the current locally adopted building code, and on a historic building confirm the profile still matches any approved landmark/tax-credit design.
4. Install continuous through-wall flashing with end dams and weep holes at the base of the rebuilt parapet before the new coping is set, not after.
5. Schedule inspections (building department, and the roofing manufacturer's rep if a roof warranty is involved) at the flashing tie-in and before the coping is set, since these are concealed-condition inspection points.
