Roof fabric eventually gives way from the adhesive, and then drops little bits of orange foam-like rubbish all over the place. Highly annoying. Have to hold it up with staples, pins or adhesive etc. until it can be fixed. Only real fix is to remove and replace the headliner. You can re-upholster them of course though, as it's just generally a piece of cardboard like material covered in a spray foam adhesive then fabric. Really stupid design for Australian climate.
