Hi Standing seam with slotted flange for attaching hidden screws (nail strip, non-clip style) What's the best method for installing the screws so that they allow the panels to move for heat expansion? I was thinking one way might be to back them out a half turn after installation.

Thanks Eric, I'll double check.

The panel manufacturer should have explicit instructions with the panel.
