Asphalt shingles decking requirements. I'm trying to find spacing requirements for lumber (example: 1 X 8 boards) for roof decking and I'm lost and can't be found. I remember when I was a carpenter we would put an eight penny nail between boards and/or sheathing; but, since the great hail storm I'm getting requests for code requirements regarding spacing of roof decking lumber and/or sheathing and can't find it in the 2009 IRC. Code section or table please. Both would be nice. Not spans, just spacing between boards and/or sheathing. Is there a maximum spacing (not more than)?
