For Iko architectural shingles (Chateau) and a standard underlayment, all I can remember from doing it before is that the roofer always runs out because the framer gave me an order quantity that was short (roofing in framer’s contract.)
The place I have to go to get some more cartons of coil nails is not convenient to this job coming up.
This time, I want to have enough. What would you figure you would need, per square? Something like maybe 600 sounds in the ball park.

I'm not familiar with the shingle you mention but, for 3 tabs, there are 25 shingles in a bundle - 3 bundles per square - 4 nails per shingle. 25x3x4=300 nails minimum per square. We usually use 6 nails per shingle on architecturals when gun nailing, so - 25 shingles x 3 bundles x 6 nails = 450 nails per square.
Is this the last roof you'll ever shingle? If not get some extra boxes just to be safe.
I see dumb people.
I've figured about 500 per square. But I ALWAYS put 6 nails in a shingle.
Like greencu said - Buy extra boxes/cases. You can always return 'em.
I always use a rough figure of 18-20 per gun nail case. It's way to close to figure it that way though when you have to run a long way to get more. Also, don't forget your longer nails for the ridge vent. A case will last several roofs.
I figured about 2#/square

But you're talking about hand-driven nails. What about the kind you drive with one of them new-fangled guns?
My roofing sub buys those
