Design

A type of beam, which supports the roof of a building. In home construction, rafters are typically made of wood. Exposed rafters are a feature of traditional roof styles.

Applications

In many buildings, rafters have been replaced by engineered trusses (trussed rafters), normally because of span limitations and/or roof load (weight from above).
