Click on the truss to select it and move it so that the exterior edge of the truss is aligned with the exterior edge of the framing layer. To convert a truss roof to a vaulted ceiling you may need to do.

A standard rule of thumb is the cathedral roof pitch can be up to one half of the roof pitch. A vaulted ceiling angles up from the top plates of the wall sections. Click and drag to draw a roof truss perpendicular to the ridge line of the roof and ceiling planes. These steel joints are needed to support the overall truss.

This design element makes a room appear larger and provides more natural light. The partial scissor truss is similar except that the bottom chord slopes up in one direction and then straight down while the remaining portion is flat. This is the distance between trusses. You will also incur additional costs because it is much harder to deck and shingle a roof that is 12 12 pitch versus a 4 12 roof.

Finally the truss calculator will compute the best dimensional method to connect the pieces of the truss with steel joints and a bridge. You can t simply remove parts of the trusses to make room for a vaulted ceiling without compromising the stability of the roof. Roof trusses are built in a truss manufacturing warehouse and delivered preassembled to the jobsite.
