My state uses the 2015 IRC. There has been substantial debate over the minimum acceptable thickness of plywood when used as roof sheathing. There has been a lot of mis-quoting of the wrong section of the code. After research I believe that you have to get to Table R503.2.1.1 which show that 3/8" plywood is only acceptable if there are panel clips spaced equally between 24" oc supports. Otherwise the plywood needs to be a minimum of 7/16". Can anyone provide additional information, confirmation, or dissent? Thanks
