Roof Labeling
Roof edge types explained
What eave, ridge, hip, valley, rake, gable, and the rest mean — and why labeling them correctly matters.
Start the interactive walkthroughEdge types drive the trim and flashing in your bill of materials. A mislabeled edge means the wrong trim — so accuracy here pays off directly in the takeoff.
Common edges
- Eave — the low, horizontal edge where water runs off (gutters live here).
- Ridge — the top horizontal edge where two slopes meet.
- Hip — a sloped edge where two planes meet on an outside corner.
- Valley — a sloped edge where two planes meet on an inside corner (water channels down it).
- Rake / Gable — the sloped edge at the end of a gable roof.
- Transition / High side / Sidewall / Endwall — where the roof meets a wall or a change in slope.
The color legend on the labeling canvas always shows the active edge-type colors for quick reference.
