Standard spacer
Use the Standard spacer almost everywhere (dark slates at right). Allow 1 spacer per standard (field) slate.
Edge spacer
Use the Edge spacer on the sides of the roof (dark slates at right) where it is not possible to use the Standard spacer. Specifically, use Edge spacers at verges (gable ends), along hips and at the right and left sides of penetrations (such as chimneys and skylights). Allow 2 spacers, on average, per edge slate.
