Roof Trusses Design Options

Roof Trusses Design

A roof truss is a structural framework made of timbers designed to support a roof. You can choose many roof truss designs, but be aware that they are essential for multiple reasons.

Besides their appearance and aesthetics, they can interfere with the roof support. There are many benefits of having a roof truss since they are less expensive than roof rafters and are stronger, and last longer. See some roof truss designs below and choose the one that fits your house or building the most.

Scissor Truss

Having up to 22 meters, the scissor truss is much used in residential home construction projects that need vaulted ceilings. Its bottom chords are sloped, which creates a dramatic ceiling in the room below it. This roof truss design has a nice appearance, especially for those who enjoy high ceilings, and it is convenient to use.

If you don’t want vaulted ceilings in all your residences, don’t worry. You can use this roof truss in one part of your house and use different designs in the rest. It will look uniform anyway. Unfortunately, a scissor truss is more expensive than other types.queen post roof truss

It is similar to the queen post truss; however, it has two vertical posts spaced further apart to make the space available. Therefore, your attic space will be as ample as your building structure width. So, if you want a significant attic space, have a broader building structure.
