Does anybody have any experience with clip/no clip metal roofing? The type with clips holds the metal roofing 3/16 of an inch above the plywood roof base. Is this designed to allow for maximum expansion and detraction? The no clip design fastens seems simpler; it fastens directly to the plywood subroof. You are supposed to not make it too tight to allow for expansion/contraction. Anybody know which design is the better choice? Are the clips worth the hassle? House is in the northeast.
thanks,ethan

Never have heard of the clips you're referring to. Any chance you have a link you could post?
*Numerous roofing manufacturers use this system nowadays; there small clips that are screwed to the roof, overhang one side (usually the right), of a "snap lock" standing seam roof, and the clips (and the right-hand leg of the panel), are covered by the snap of the next panel. They are fastened tight to the roof, and because of their size, hold the roof in place. The panel can expand and contract within the "holding area" of the clip. This is one method. The other is to have a built-in fastening flange on the right-hand side of the panel that you screw to the sheathing, and then the snap-lock goes over it, hiding that flange. I haven't had experience with the flange method, since it's generally not used here...but I like the clip method, because, to a certain extent, it allows the two materials (sheathing and roof panel), to be somewhat indepenent of each other. Sorry I can't be of more help.
