How to Reglue a Car Roof Liner

Kick that sagging car roof liner to the curb. Give a car's interior a new license on life and reglue the car roof liner. Forget vacuuming up any more crumbly foam backing with a freshly glued liner. Hit the road and not your head on your car's ceiling with these steps to reglue a car roof liner.

Remove all the interior trim panels supporting the car roof liner shell. Use a screwdriver for any screws. Reserve screws and trim pieces.

Slide the shell out the car door. Be careful not to crack the shell on its way out.

Peel off the liner material from the shell backing slowly. Brush off all of the old foam backing from the shell and liner. Scrub any old adhesive residue off of the shell.

Cut out any holes for dome lights and other ceiling features from a new high quality foam backing. Spray a heavy duty adhesive glue (designed specifically for bonding) onto the foam backing. Press foam backing back onto clean shell.

Spread the fabric over the foam backing leaving a few inches of overhang on the windshield side. Spray fabric adhesive on the backing by the windshield side and tuck the material over tightly to create a clean edge.

Spray the rest of the foam backing with the fabric adhesive spray and spread the material over the backing. Smooth out any wrinkles and pull the material tight. Let dry.

Reinstall the shell with support trim once glue has dried.


Seek professional assistance for removal of electric sunroofs in order not to damage mechanical parts. Electric sunroofs generally have to be removed before interior shell can be removed. Removal of front or rear windshields may be required for cars with large shells or older cars with suspended headliners.
