What is happening is that the urethane foam padding has broken down and
turned to goo, and so your headliner is no longer attached with the foam.
Replacing the headliner is not a difficult job; a lot of fabric stores carry
the headliner material... you take the ceiling out of the car, scrape it down,
apply 3M #33 adhesive and glue the new material in, then put it all back.
If you don't want to do it yourself, any auto upholstery place should be
able to do it. It's an easy job and should not cost too much.
