Abstract of the Disclosure A sliding clip for a floating standing seam roof for allowing buckling of the roof panels to relieve exces- sive thermal expansion. The relative arrangement of the stops which limit the motion of the upper clip portion in respect of the lower clip portion is asymmetrical to allow a greater admplitude of motion of the upper clip portion toward the fixed ends of the roof panels caused by contrac- tion than is permitted toward the floating ends of the roof panels caused by expansion. This prevents destruction of the clips or of the fastener for the fixed ends. It also prevents rupture of the panels themselves at their fixed ends.
