Depending on where you want to build, some places require more structural support to take on a heavier load. You may have noticed deeper looking roofs in areas with high snowfall. Engineered roof trusses use a combination of depth and webs to take on high snow loads. Although timber beams and roof joists are strong, sometimes the most cost-efficient way to attain support is by using engineered trusses.
The webs are triangulated to support any static or point loads along the top and bottom chords of the truss. The trusses are also engineered to work at an optimal depth for cost efficiency.
On Center Spacing (o.c.) also plays a big roll in supporting the roof. Typically, the on center spacing for trusses is 2’-0”, but when dealing with a heavier snow load, trusses may need to be placed closer together.
Lumber size also helps with supporting a heavy snow load. The top chord, bottom chord, end verticals, and webs all need to be sized correctly to pass engineering.
Engineered trusses are usually hidden above the ceiling so your timber beams can remain the star of the show. The combination of the two create a beautiful cost-effective team. For more information, please contact Tamlin.
