He has 2x10 listed in the heading. My code book says you have to have full contact with the ridge and valley board if there is one, I do agree with you that the ridge board doesn't carry much weight. But I don't think the code is for ridge board sag as ridge board sizing is dictated by rafter size and roof pitch (plumb cuts on rafters). Bud9051.A 2 x 12 at a 6/12 pitch would be 8-3/8" if using the 2/3rds rule. You can always talk to the Architect. But that sounds a bout right compared to a lot of ridges we put in. We put in a 3 1/2" x 14" glulam with lvl top/bottom chords that is the ridge for a 16' w x 16 or 18' long master bedroom.An important difference is a design with a supporting ridge beam. A heavy ridge beam can be designed to carry the top ends of the rafter's load to posts thus eliminating the need for collars such as in a cathedral ceiling. This type of ridge beam and its supports are very important structurally. 8.
