A crow-stepped gable, also known as a stepped gable or corbie step, is a design for a building’s triangular gable end. It takes the form of a stair-step pattern at the top of the stone or brick parapet wall which projects above the roofline.
Used as decoration, as well as being a convenient method for finishing brick or stone courses, crow-stepped gables were traditionally used on Dutch houses, Danish medieval churches, and Scottish buildings dating back to the 16th century. They were also a feature of the northern-Renaissance Revival and Dutch Colonial Revival styles of 19th century America.

- Cutting a groove approximately 25 mm (1 inch) deep to the inside edge of the steps and inserting a lead abutment flashing.
- Lead flashings placed into the joints between bricks as they are laid.
