Roof trusses are very large beams that are used to hold up the weight of a home's roof, versus standard roof joists and studs. Roof trusses are often used when you want to add height to a ceiling or keep those beams exposed for a more rustic and natural look. If you're thinking of using roof trusses in new construction or of having them retrofitted into your new home, not a few things you might want to discuss with your contractor, so you know if they're right for your home and are sure to choose a style you love.

Can trusses be connected to other roofing components?

If you only want to expand or raise a part of your home's ceiling, a contractor can usually use CAD, or computer-aided design, to configure the use of new trusses with the roof's current components. This can allow you to keep part of a second story, such as the section that is over the back of the home, while opening up just part of the first story, such as in the home's entryway or foyer. Ask your contractor about this option if this is your preference.

Are roof trusses expensive?

If you're concerned about the cost of the trusses, discuss this with your contractor so he or she can work with your budget and help you compare costs of trusses versus standard joists and studs. Depending on the trusses you choose, they can actually be less expensive than standard stick built roofs. A roof truss is built in a factory and then trucked to the location when they're needed; being made to precise sizes and with exacting calculations means there is less wood waste, which can result in less cost. There is also typically less onsite labour needed with roof trusses, as they can be fastened together without the aid of a specialty carpenter. There is also little to no risk of the trusses being stolen off a jobsite, since they're delivered when needed.

Choosing the style

Be careful about the style of truss you choose; ones with lots of beams, such as between the main triangular frame, can soon look busy and cluttered, and especially if you're having them installed in a smaller home or need several trusses to support the weight of the home. Note, too, if you want something unique for the home; scissor and queenpost styles are very traditional, but a more square flat or sloping flat truss can look modern and more simple than other designs.
