Can You Repair Car Roof Upholstery Yourself? Your Top Questions Answered

What causes headliner to sag?

The adhesive breaks down over time. Your car’s headliner is actually made with 2 different materials—polyurethane, a foam-like layer that goes directly over your car ceiling, and a layer of fabric that goes on top of the polyurethane. This headliner stays in place with an adhesive; over time, as the glue breaks down, the headliner starts to droop and sag off your car’s ceiling. Typically, car headliner starts to sag after 10-15 years.

How can I fix my headliner without removing it?

Glue the edges and sides back into place with a spray adhesive. If your headliner is sagging along the edge of your car ceiling, a quick touch of glue can do the trick. Spray the loose, peeling underside of the headliner with the adhesive, along with the exposed section of ceiling. Wait 5 minutes for the glue to get tacky, and then press the material back into place. Some people like to spray on 2 coats of adhesive for extra security.

Secure loose edges with double-sided tape. Stick 1 section of double-side tape along the peeling underside of the headliner. Then, stick the tape onto your car’s roof. This is an easy fix for any peeling sections along the edges of your headliner.

Use pins for a quick fix. If your headliner is sagging badly, you’re better off replacing it altogether. However, if you’re in a rush, stick a couple of pins through the drooping material to hold it in place.

What is the best glue to use on a headliner?

A high-temperature adhesive spray is best. Spray glue is easy to apply in an even layer, and helps your headliner stick firmly to the backing board. Professionals recommend using a high-temperature adhesive—about 2 cans are enough for a standard sedan, but you might need more if you’re repairing a larger vehicle. Professionals recommend using 3M-brand “hi-tack” adhesive spray for headliner repairs. You can also use an adhesive spray designed specifically for car headliners, too.

What if my headliner is sagging in the center?

You’ll need to replace the entire headliner. Unfortunately, there’s no quick or handy way to re-glue the center of your headliner onto the backing board. Instead, you’ll need to remove the headliner completely and replace it with new fabric.

How do I remove the fabric from my car ceiling?

Detach any accessories from your headliner first. Sun visors, grab handles, car lights, and other accessories are typically attached to the top and upper sides of your car. Before removing the headliner and backing board, unscrew all these attachments and set them aside for later. Depending on your vehicle, you may need an electric drill, pliers, screwdrivers, and/or a hex tool socket kit to remove these accessories.

Pull down the plastic pillars and sills. Find 4 plastic “pillars,” or sections of plastic layered over your car’s headliner, along the front and back of your vehicle. Remove any plugs or screws holding these pillars in place. Then, pull off any sills, or rubber strips, along the sides of your car doors. You don’t have to remove the pillars! The pillars only cover about 1 in (2.5 cm) of the headliner material—so, you can shift and pull out the old headliner without detaching them completely.

Remove the headliner and backing board from the car entirely. Grip the headliner and backing board with both hands, removing them completely from the top of the car. Open up multiple car doors, so it’s easy to slide the backing board and headliner out.

Do I need to do anything else once the headliner is removed?

Disconnect any wires and sunglasses cases. Flip the backing board over and place it on a flat surface. Unscrew any wires still attached to the board, setting them aside for later. Additionally, unscrew and remove any sunglasses cases from the headliner—these are pretty fragile, and will likely break if you leave them attached. Always reattach these screws, wires, and cases before placing your headliner and backing board back in the car.

What type of replacement fabric should I use?

Flat-knit and velour fabrics are both great options. Flat-knit headliners have a “stitched” design, while velour materials are softer to the touch. Both of these materials come attached to a layer of foam, which goes directly on the backing board. These fabrics come in different colors—feel free to pick one that matches your car’s interior. You can find headliner fabric at specialty shops, or at stores that sell auto supplies or fabrics, like Walmart and Hobby Lobby. It typically costs over $10 per yard.

How do I replace the car roof upholstery?

Peel off the old fabric. Don’t try to salvage the old material; instead, just remove the headliner fabric. The foam might be stuck to the backing board, which is perfectly normal.

Remove the foam from the headliner board. Grab a bristled brush and scrub off the old foam. Clear away the foam completely, so the backing board is completely bare. Then, smooth away any raised sections or imperfections on the backing board with a sander. An air blower or air hose can help with this.

Glue a new section of fabric in place. Spray down the entire backing board with adhesive glue, as well as the underside of the new headliner material. Wait 5 minutes, so the glue gets nice and sticky. Use your hands to press and smooth the headliner over all the contours and raised sections of the backing board, so the material looks seamless and wrinkle-free. Then, let the glue dry and cure completely. Check your glue can for more specific drying and curing guidance.

How do I reinstall my new upholstery?

Cut out any sections of fabric where car accessories will go. Grab a razor blade and work your way around the new headliner material. Carefully cut around any sections where car accessories go, like your interior lights, grab handles, and sun visors. These sections appear slightly raised beneath the material and are easy to locate and cut out.

Secure the headliner and backing board to the interior roof of your car. Then, reattach and secure any sills, pillars, and side accessories that you originally removed from the vehicle.

Clean off the new upholstery. Spray down your new headliner with a foaming spray cleaner. This keeps your new material sleek and fresh without actually staining the headliner.

How much does it cost to repair your headliner?

It typically costs $200-350 at a repair shop. If you’re getting the repair done at an auto dealership, the repair can cost anywhere between $650 and $850. Don’t worry—if you’re completing the repair yourself, the supplies only cost around $50 to $55, depending on what type of vehicle you have.
