Rafters and trusses are typically built to support roof systems. Truss construction is now more commonly used for new homes, but roofing contractors may also recommend rafters for certain roofing projects. Make sure that you have a bit of knowledge about these structures because rafters and trusses are basically the ones that will hold up your roofing.

In this post, roof repair and installation expert De Palma Construction shares a quick guide to rafters and trusses.

What Are Rafters?

Rafters are also commonly referred to as “stick framing.” They are made of 2 × 10 or 2 × 12 planks, which provide support to the roof and roof sheathing. Rafters typically slope down from the central ridge beam at the peak of the roof. They intersect with exterior walls, and they are often built along with ceiling joists to further stabilize the roof and attic structure. These ceiling joists are extended horizontally across the floor of the attic space so that they can properly secure the walls.

What Are Trusses?

Truss is a prefabricated wooden structure that is designed to support residential roofing. It uses a triangular webbing of structural members, enabling it to support the roof while also tying the outside walls together.

Furthermore, the beams and ties of the interior triangular webbing of trusses will ensure that the weight of the roof is distributed over a wide area. A typical roof installation project uses multiple trusses, and roofers make sure that these trusses are evenly spaced from one end of the home to the opposite end.
