Actually, was 2 x 6 (4/12 pitch) for all with singles for hips which were already failing 3 years ago when I looked at it the first time. Some butcher tried to re-inforce with sistered 2 x 6's for the hip but didn't run full length, bolts sheared right through. Warned him it would happen eventually, and it did. My accountant isn't the shoveling type.
