The roof frame and uppermost joist layer form a cohesive structure. Rafters mortised into joists form the simplest roofs. Rafter feet can also be set with their heels at the beam end or may be saddled over a wall plate above the beams.
When mortised, the rafters sit some distance in from the beam ends, and the roof covering must be raised with sprockets at the rafter feet.
The figure to the right shows a typical (mortised) solution, as well as an example of very small cornice built of ordinary brick.
