Trusses VS Rafters: What’s the Difference?

 

Trusses and rafters are two different roofing systems used in construction. In simple terms, rafters are single boards used to create a roof structure, usually for a flat roof. On the other hand, trusses are prefabricated structures that can be set in place and span a larger distance with less wood. Trusses can also be built in a factory and set in place, while rafters have to be built in place using conventional framing.

 

The major difference between trusses and rafters lies in the structure of the roof and the attic space. A flat roof built with rafters will have limited space, with no attic, and no access to the space once it’s closed up. In contrast, trusses provide an attic space, and there is access to the space, making it easier to maintain, repair, or replace anything inside. Trusses also provide more space for insulation than rafters.

 

If a pitched roof is built with rafters, it’s referred to as conventional framing. However, a pitched roof is typically built with trusses as they can span a larger distance with less wood. Trusses tend to be more expensive than rafters, but the long-term benefits make it worth the investment. A pitched roof built with trusses is less likely to have issues with waterproofing compared to a flat roof, as water runs downhill on a steep pitch.

 

It’s recommended to use trusses whenever possible, but sometimes it’s not possible. In such cases, it’s important to plan the project properly to accommodate the space between the rafters.

In conclusion, trusses and rafters are two different roofing systems with distinct advantages and disadvantages. Trusses provide more space, access, and insulation than rafters, but tend to be more expensive. It’s recommended to use trusses whenever possible, but if that’s not possible, it’s important to plan the project properly to accommodate the space between the rafters.
