There are many components to a roof, but the three main components are joists, trusses and rafters. All of these components put together help to create the shape of the roof.
- Joists: Joists help to evenly distribute the weight of the roof and structurally support it.
- Trusses: Trusses help with the structural framework of the roof and support the inclined, vertical, and horizontal beams of the roof.
- Rafters: Rafters help to support the roof deck, shingles, and support the roof along with the joists and trusses.
