try taking a 6 foot level and laying it against the bottom of the panels to take a picture of how far out it is from other areas in the same area which are not affected. measure how far out (in) they are pressed.
we can tell this is damaged but how far in are they.
think like a police officer when doing your report to them and add measurements of length, panels involved, (sticky notes with numbers) and measurements of how far the deepest and shallowest points are on each panel.
take dozens of pictures.
