RAfter spacing different on each side of ridge
Are there any reasons you can not or should not space rafters at differnet spacing on each side of a ridge. I am looking at a situation where I have a clear span on one side of teh ridge and the same overall span on the other side but with a solid bearing wall about one third of teh way up from the outside edge. The side with the mid-bearing point could easily get by with 24 OC spacing, but the clear span would need 16 OC.
Again, assume a ridge BEAM. And does the answer to this question depend on wheather the rafters are set atop the beam or hung on the side of teh BEAM (not a board)?
Thanks.

Yes.
If the beam is a bearing ridge and designed to carry the off-set loads you could do it, or......
You could frame the upper half of the short span @16" OC to match up to the other side at the ridge and then frame the lower section @ 24'OC from the bearing wall to the outside wall.
But, at 24" OC you may need larger rafter stock than you can use on the 16"OC layout,depending on the span,check your rafter tables.
Everything depends on your loads(snow) span, pitch, etc...
Hope this helps a little,
