How to size a ridge beam.
Ridge beam vs truss for 30 foot span. Looking to frame a lakefront home (30 x 42) with 10/12 pitch. I know truss’s would be simpler but we wouldnt get a loft and I would still be concerned about a little snag in the heavy snow load area. It looks the the rafter span would be just over 19 feet which I thing would really be pushing the limits.
