We are replacing a metal roof that is installed on 1 x 4 horizontal laths. We feel better putting down decking instead of installing the new roof on the laths.
Do you know if the new plywood decking should be installed directly on the rafters or on top of the existing lath? I think it would be structural stronger attached directly to the rafters, but I don't know for sure.
Thanks,

This really would require inspection by a structural engineer to answer for certain. However, provided the lathe is in good shape and well-secured itself, it is not unusual to put decking over lathe. You can always fasten through the lathe and into the rafters.
Keep in mind that decking over the lathe will raise the level of the roof. This could come into play as a naegative if you have any roof to sidewall areas.
