What’s the Difference Between Roof Rafters and Trusses?

When building a new roofing system, you need to consider how you will support its structure. If you have a sloped roof, you’ll need to decide between rafters or trusses. Moreover, both constructions come with their own sets of pros and cons. You’ll need to consider various factors when choosing which one is ideal for your roof and home.  

Read on to learn about the difference between rafters and trusses. 

Rafters vs. Trusses

Rafters refer to elongated planks that are typically around 2 x 10s or 2 x 12s. These planks slope down from the central ridge beam at the roof’s peak and intersect with the outside walls. They provide support to the roof and sheathing. Ceiling joists, along with the rafters keep the roof and attic structurally stable. 

On the other hand, trusses are manufactured wooden structures that create a triangle-based webbing to hold up a roof. They are also vital to the process of tying with the outside walls. Residential roofing systems usually have multiple trusses at an even distance over the length of the house. Trusses are typically made in factories and brought to the site during installation. 

Which Is Ideal for Your Home

An experienced roofer can help you determine whether rafters or trusses are ideal for your home. When choosing between the two structures, you’ll need to consider the architectural design of your home. Trusses are more common in U.S. homes, but custom-designed houses may still utilize rafters for the roof. 

With rafters, you will get more attic space, which you can use for storage or turn into a room. It’s also great for those interested in a cathedral, vaulted or other specialized ceiling designs. Meanwhile, your contractor can install trusses within a day or two if they are small enough to be lifted by at least two workers. The beams and ties of the interior triangular webbing of trusses can effectively distribute the roof’s weight in a wider area.
