Building usage can play a significant role in how a building is constructed, and truss roofing systems can offer a lot of benefits for buildings that need to space large open areas in the building while minimizing the need for support posts in the center.

1. Truss Roofing Systems

The idea behind a truss roof is to avoid the need for support columns in the building. The entire weight of the roof can be supported with an adequately constructed truss, but the angles are critical and should be designed by an engineer. Trusses can be built from wood, metal, or hybrid materials, but the longer the span is, the more strength is required from them.

The truss's ends rest on the outer walls of the building, and as long as the walls are strong enough and the design is right, the space under the truss roof can remain free of verticle support. Building trusses are commonly used for commercial and residential buildings, and while the truss-style may differ from building to building, the concept is the same.

2. Custom Trusses

Often when a contractor is building a new house or commercial building, they will need building trusses for the structure. It's common to order them from a specialized company because the contractor needs to be sure they are getting the perfect truss for the building. 

One mistake in the design or construction of the truss could cause them to fail and the roof to collapse. A truss failure often damages the supporting walls on the structure as well, so working with a company that is certified to build structural building trusses and has a track record of excellent work is the best option.

Once the trusses are complete, the builder will ship them to your job site so that you can set them in place. Take a few minutes to look over the building trusses to ensure there are no apparent issues or damage from the shipping. If you see anything that is concerning, call the engineer before you put the trusses in place and discuss your concern with them.

3. Setting Building Trusses

When the contractor is ready to set the building trusses in place on the walls, the easiest way to get the trusses in place is to lift them with a crane. The crane can support them and allow the crew to move it around to get it the correct spot. 

Once it is set, the crane operator will lift another to the roof until they are all in place. Sometimes the crane operator is the delivery driver that brought the trusses to your site but check with the company because if they don't provide lifting service, you may need to hire a crane operator that has the proper experience.
