Here are general instructions to replace a headliner. To repair a small hole or tear in a headline, peel it back, brush off the old glue, spray with fresh headliner contact cement per directions, and relay the fabric. You might use push 'T' pins or sewing pins to hold the fabric in place while the glue sets.

To replace the entire headliner, search for headliner repair & supplies. Order the fabric color you want and at least 1 can of spray adhesive. It's not too hard, but each car is different.

Generally, you remove sun visors, trim panels for lights and switches, inside trim on the windshield 'A' pillars, roof-mounted hand holds, coat hanger brackets, and trip around doors and tailgates (on SUVs and minivans.)
In many places, screws are hidden behind trim caps.
After you have removed all the trim pieces, the headliner panel should drop down from the roof. With a minivan, SUV, hatchback or station wagon, remove the panel from the rear liftgate area. With a sedan or coupe, tilt the panel and remove through whichever door opens widest. Usually the front doors.

Place the headliner on a table or sheet of plywood over a pair of sawhorses. Peel off the old headliner fabric and discard. Carefully brush off all the old adhesive using a stiff brush, such as nylon floor scrub brush. Roll out and cut the fabric wider and longer than the headliner, perhaps 1" longer/wider. On the front windshield, leave 2" overhang to let it roll over the edge. Dry fit and adjust the fabric over the headliner. Fold 1/2 of the fabric back onto itself, then spray the adhesive over the headliner in strips going both length and width, to assure good adhesive coverage. Relay the fabric over the adhesive and smooth wrinkles with your hands. Repeat with the other half of the fabric: spray adhesive, relay the fabric and smooth wrinkles.
Using a sharp utilty knife blade, cut any openings for light wells, etc in the fabric. Trim the fabric around rear and sides, but not yet the front. You want to spray more adhesive on the front underside of the headliner, roll the fabric over the edge and smooth wrinkles.

Carefully replace the headliner into the vehicle, align the holes and light wells, and re-fasten all the screws and other fasteners you removed. Replace all the trim pieces and admire your work.
