This is one reason why we always use solid board sheathing rather than nailers whenever possible.

I have not put the nailers up yet. They will be installed on 7.5" centers. The first three from the bottom will be at unique locations since I have to accommodate the starter course of slate.

What I can do though is make the spacing between number 3 and 4 nailer be smaller than 7.5" on center. This will subsequently cause the nailing holes in the slate not to line up with the horizontal center line of the nailer but allow the top of the slate to sit more on the second row up nailer. My question is still how much should the top of the slate sit on a nailer? Is 1/2" okay? Thanks.

If your spacing is consistent they should be on-center or close to it.

What stage are you at? That really is the best way to determine what variable to change.

Have you already installed the nailers? If so, are they spaced 7.5" o.c.?

I already have the slate and the oak nailers. It would be easier to buy new strapping like 1" by 4" than to get new slate. I was thinking though that I could nail the slate a little off center (higher) on the strapping. That would put more of the top of the slate on the piece of strapping located two rows up.

So my question now is: how much of the top of a field slate should sit on strapping? Thanks.

If you have already installed the strapping as you described, than the nail holes should be placed 6.75" from the top in order to hit the nailing surface.

Are you just in design or have you already framed the roof?

Is the slate already quarried?

Maybe use 1X4 rather than 1X3 nailers.

So the answer is that the top of the slate needs to sit on wood strapping, right?

You will have to adjust the position of the nail holes also. If you have not already ordered the slate, hopefully you can get the quarry to punch them to your specifications.

Yes the "lath" or strapping should be spaced 7.5" on-center to match the exposure of the slates.

I built a timber frame structure and am now trying to hang a slate roof. The slates are 12" wide and 18" high. The nail holes in the slate are 6" down from the top. The exposure is 7 ½". I am using 1" by 3" white oak strapping to hang the slate.

If I nail the slate such that the nail is centered in the strapping, the top of the slate just misses the second row of strapping above. So the top of the slate is unsupported. This does not seem correct. Should I adjust the position of the strapping so that the top of the slates fall on wood instead of air? Thanks.
