What to Do When the Car Roof Lining Falls Off?
3 Answers
Use roof lining-specific glue, apply it along the fallen edge, and once the glue dries and hardens, it will bond. Choose clips of a similar color and nail them back in place, or use a syringe to inject glue for adhesion. Remove the entire roof lining, prepare a new piece of roof lining fabric, spray glue on both the car roof and the inner side of the lining, and then bond them together.
Some time ago, the headliner in my own car also started to sag. At first, only a small piece came loose, but it gradually got worse. I tried using thumbtacks as a temporary fix, but this was only a stopgap measure—thumbtacks can easily scratch the interior. Later, I learned that headliner sagging is mostly due to the foam aging, and exposure to high temperatures accelerates the glue failure. Replacing the headliner fabric at a repair shop costs around one to two thousand yuan, but it can last three to five years. If you're on a tight budget, you could try using strong spray adhesive. A friend of mine did it himself: first, clean off the old glue thoroughly, spray the new adhesive, and press firmly for ten minutes. Remember to keep the windows open for ventilation for two days—it can hold up for over a year. Also, try to park in the shade and avoid rubbing the headliner with hard objects.
I just experienced this issue where the middle of the car roof suddenly sagged after being exposed to intense summer sunlight. Initially, I tried fixing it with double-sided tape in several spots, but it came loose again after some bumps. Later, I took it to a repair shop, and the mechanic said it's a common problem for cars over five years old—poor-quality glue can cause detachment. There are two repair options: 1) Partial patching with new fabric, costing around 200-300 RMB; or 2) Full roof replacement, including bracket restoration, which costs roughly over 1,000 RMB. I opted for the latter and chose a synthetic leather material, which is heat-resistant and easy to clean. My advice: first assess the extent of detachment and your budget. For small areas, you can buy specialized glue and DIY, but for larger sections, it's best to consult a professional—DIY attempts may leave wrinkles and affect aesthetics.
