Aluminium sheet Roofing- wobble board. Unstuck or normal

Hi Is it normal for a all Alluminum roof to become like a wobble board during the hot weather of summer ?
I understand sheet metal expands, but, wondered if this is normal. As thought the roof sheeting to the frame would have be stuck down to the wooden framed structure. So maybe came unstuck.

Hi Roger, no its not normal and while sheet does distort in different temperatures you shouldn't notice it at all, is there any sign of damp on ceiling?
Alternatively whatever it was bonded to wooden frame with may have deteriorated.

Requires further investigation starting with sunroof removal (if one fitted) and have a look see
