plywood

  1. A

    R503.2.1.1(1) code on roof sheathing thickness

    Am I reading it right that if I have 60psf snow load in my area (thats what trusses are engineered for), I could not use 7/16 osb because that only allots 40psf with 24" O.C? I would have to use 15/32 plywood they dont sell 15/32 osb where I am at, or 19/32 OSB? I will probably go with 15/32...
