is 1/2" plywood for sheeting thick enough for new constuction in Florida for a tile roof or does it need to be 5/8" ?
As always check your codes but up here 5/8" or 3/4" is more common for any roof deck. With tile roofing It is safe to say that 1/2" is not sufficient, Its a lot of weight.
1/2" is to lite for tile in my opinion.
im in tampa bay if ya need help.
5/8" minimum, SW florida
