Ridge Cut

Definition

A ridge cut is any cut made in a vertical plane; specifically, the vertical cut at the top end of a rafter.

Purpose

The purpose of a ridge cut is to ensure that the rafter fits properly against the ridge board or beam, allowing for a precise and secure connection in roof construction.

Examples of Use

• In gable roofs, ridge cuts are made on rafters to fit them securely against the ridge beam.
• Ridge cuts are used in hip roof construction to ensure the rafters meet correctly at the roof's peak.
• When constructing dormers, ridge cuts allow for a seamless connection between the dormer rafters and the main roof.

Related Terms

• Ridge Board: A horizontal board at the peak of a roof where rafters meet.
• Birdsmouth Cut: A notch cut into a rafter to allow it to sit securely on the top plate of a wall.

Notes

Accurate ridge cuts are essential for the structural integrity and alignment of the roof, ensuring that all rafters fit correctly and provide even support.
