Parallel chord truss vaulted roof
For a parallel chord truss vaulted gable roof with an 8/12 slope, a total horizontal span of 27ft and a snow load of 42psf, what would be the truss depth and lumber size required? I found numbers for a 40psf snow load flat parallel chord truss spanning 27ft with 18″ depth and 2X6 top chord and 2X4 bottom chord. Would this also apply for a vaulted roof with the same span, but closer to 32ft total length (16ft for each side of the roof)?
