If the nails are overdriven, do another nailing pattern in the gaps that is correctly driven. What is your code? We do 7" on the edge and 12" in the field, plywood or osb. OSB is actually preferred for some reason.


OSB is not as tolerant of getting wet during construction. I'm building this on weekends and I live in Portland... I went with plywood.

6" on edges, 12 in the field. The issue is there is a limit to how many nails are allowed since it can cause splitting of the 2 x 4 behind the panel. In some areas he was spacing nails every 4". Those will probably need to come out.

The correct solution is as you noted, drive another pattern or if I'm past the allowed number of nails, pull the over driven ones. The other solution is to de rate the panel. I used 1/2". If a nail is driven so that wood under its head is 3/8 thick, then you use use the code for 3/8" plywood.

Either way I'm OK, it was just annoying as all hell. And the overdriven nails just look hack.

He's a great kid... But like anyone, makes an occasional mistake.

We did make good progress yesterday. 27, 24 foot rafters are up and blocked in place. I'm guessing we lifted about 3400 lbs of wood to the ceiling.
