 code help / poor rafter fit

Arkansas uses the 2006 IRC. Table R602.3(1) specifies the nail schedule for connections between the rafters and the ridge. 4-16d if toe nailed, 3-16d if faced nailed.
The WFCM might have more but I haven't a copy.

Kevin, the APA has text and a drawing in their roof framing specs that state "rafters should bear fully upon the ridge board to prevent horizontal rotation."
I saved the drawing at some point, but can't readily locate it. If you Google "rafter ridge board prevent rotation," you'll find similar references.

I'd just use R802.3 it states "to" not close.
2006
R802.3 Framing details. Rafters shall be framed to ridge board or to each other with a gusset plate as a tie. ...

Kevin,
If only he had used "10 pounds" of nails ... then it would be OK!!

Further in the passage to the reference provided: IRC 2006 R802.3 "Ridge board shall be at least 1-inch nominal thickness and not less in depth than the cut end of the rafter."

Thanks for the replies. The issue wasn't the number of nails attaching the rafter to the ridge, and it wasn't the depth/height of the ridge. It was the fact that the rafters were cut on a different angle than they should have been, and that they didn't meet the ridge. Here's a pic of one of the affected rafters. (I count at least 11 nails for two opposing rafters.)

I don't see a problem with it. It's how you're looking at it. See if you look at it as a wood rafter not bearing on the ridge board (boooooring) then yeahhhh there may be an issue, BUT!!!!, if you look at it as a steel reinforced rafterhead with a seismic gap for the roof to move with the shaking.... then it's perrrrrrrfect!
