A contractor installed a 24 GA, standing seam,double lock, concealed fastener floating clip roof system. During the installation, the roof seam was not hand crimped at the roof clip, except at the first clip, and during the seaming of the roof the electric seamer did not produce the double seam as required for the roof. Instead, the two panel pieces and the roof clip were folded down on the seam and not interlocked. The roof panels do not form even a single 90 degree seam but instead go straight up from the roof along with the clip and then make a 180 degree turn and come straight back down. The doble lock which requires a second turn up does not occur. For all practical purposes the roof clips are not engaged. Is this a normal practice in the industry or a fix required? Will the roof still have wind uplift resistance without engaging the clips? Any ideas on how to fix the clip? Can a cap be placed over the roof clip?

Tony,
Not sure I understand exactly what you're saying -- the entire seams have not been double-locked or just over the clips?
Anyway, not seaming a panel designed to be seamed undoubtedly jeopardizes its uplift resistance and possibly weather resistance as well.
If possible, I would suggest contacting the manufacturer of the roofing for their input.
If you like, email me pictures of the roof at [email protected] for my further input.
