long unsupported rafter spans
Does anyone have a link to a rafter span table ? I’m framing a house with a 20′-7 1/2″ run from 1st floor wall to 2nd floor beam. It’s a 6/12 roof and the rafteres are about 26′. No loads other than composition shingles and drywall underneath.
I know I should just google this but I’d like some feedback, too.
I’ve done a similar house with a slightly shorter run using 2×10 with a couple of rows of bridging blocks and it worked fine, I’m just wondering if I should beef up to 2×12 or use I joists. I’m not even sure if I can get 28′ 2×12 in my neck of the woods and most likely the lumberyard will send me fingerjointed 2×10 at this length…
