It is very common for Holden roof linings to fall down, after 5 years the foam backing begins to deteriorate and the material may start to bubble and peel away from the edges. If any edges are exposed you may start to get orange foam particles falling from your roof. The best way to fix this is to have a technician come and replace the material, the material needs to be replaced trying to glue the old material backup may result in damaging the board when new material is applied the lumps from the glue can show through so this is not a recommended fix. Some people like to use pins or thumbtacks but this also is not recommended tho it can hold the material up for a quick fix, but there is wiring on the back of the board that could be damaged.
