Depending on where you want to build, some locations 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. Tamlin’s post & beam systems often combine engineered roof truss components to meet and exceed structural engineering requirements.
There are many different engineered truss designs including this parallel chord roof truss. In order to achieve a higher strength, the depth of the truss is often adjusted.
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. Tamlin’s “in-house design team and engineering partners will ensure you have an optimal balance of design, cost, and strength for your home. For more information, please contact Tamlin.
