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.
