Heel, Rafter

Definition

The Heel of a Rafter is the end or foot that rests on the wall plate.

Purpose

The heel of the rafter is a critical connection point where the roof structure transfers loads to the walls of the building. Proper placement and securing of the rafter heel ensure the stability and integrity of the roof and overall structure.

Examples of Use

1. Roof Framing: Securing the rafter heel to the wall plate in traditional roof construction.
2. Truss Systems: Connecting the heel of prefabricated trusses to the top of walls.
3. Dormer Construction: Attaching dormer rafters to the main roof structure.
4. Shed Roofs: Supporting the lower end of rafters in single-pitch roof designs.

Related Terms

• Wall Plate: The horizontal timber on top of a wall, where rafters are seated.
• Birdsmouth Cut: A notch cut into a rafter to allow it to sit securely on the wall plate.
• Roof Truss: A prefabricated, triangulated wooden structure used to support roofs.

Notes

Accurate measurement and cutting of the rafter heel are essential for ensuring a secure fit and proper load distribution. The heel must be properly anchored to the wall plate to resist wind uplift and other forces.
