What’s the Difference Between Rafters and Trusses?

Your roof is your home’s first line of defense against the elements. However, it won’t be able to do its job without structural support. There are two types of roof support: rafters and trusses.

Here are the key differences between the two as well as their respective pros and cons.

The Difference Between Rafters and Trusses

The main difference between rafters and trusses is the way they are assembled. Rafters are built manually through a method called stick framing while trusses are manufactured in factories. 

Rafters: What Are the Pros?

• Roof rafters take up less space. Most contractors would recommend choosing roof rafters if you’re planning to convert your attic into a living space. That’s because they take up less space and create a larger attic space.
• It’s easier to install insulation in attics built using roof rafters.

What are the disadvantages of using roof rafters? Rafters have to be built manually, which means construction will take longer. Not to mention your attic conversion’s labor costs will be higher. 

Trusses: What Are the Pros?

• Attic conversions that use trusses have shorter project timelines. Roofing contractors don’t have to assemble roof trusses since they’re manufactured in the factory and are delivered ready for installation.
• Trusses are less expensive than rafters. A study by the National Association of Home Builders found that the material and labor costs of houses built using trusses were 16% lower than houses built using traditional rafters.

What about the disadvantages of using roof trusses? Attics with trusses tend to be smaller than attics built using rafters. Keep in mind that local building codes have minimum space requirements for attic conversions. That’s why before starting an attic conversion, you should consult an experienced roofing contractor.
