The detachment at the edges of the headliner is likely due to the aging of the fabric sponge, causing the edges to come loose. Purchase a bottle of specialized automotive adhesive or glue product and reattach it. If the middle section of the headliner is sagging or detached, and disassembly is inconvenient at this time, you can opt for a clip repair. In this case, the entire headliner needs to be removed, and the old fabric must be taken off. For the best results, it is recommended to have it handled at a repair shop.

I've encountered the issue of a sagging car headliner and successfully repaired it myself. The cause is usually adhesive aging or moisture in the roof lining. For small detached areas, DIY repair is possible. First, purchase specialized automotive upholstery adhesive from an auto parts store - it only costs about ten yuan per bottle. Clean the roof thoroughly, wipe away dust and old adhesive residue with a damp cloth, and spray some alcohol for disinfection to ensure no grease remains. Then evenly apply glue to the detached fabric, carefully press it back into place, and secure it overnight with large clips or books to let the adhesive set. Ensure proper ventilation during the process to avoid inhaling fumes, and handle gently to prevent fabric damage. For larger detached areas or worn-out fabric, you might need to replace it with new material - cutting it to size yourself can be more troublesome. With some time and patience, you can save hundreds in labor costs. The key is preparing all tools in advance to avoid mid-process confusion.

This is not just an aesthetic issue! If the ceiling fabric falls off while driving, it could block your view or drop dust onto your face, easily causing an accident. I once experienced a small piece falling and nearly affecting my driving, which scared me into stopping immediately. Worse, dust can enter the air conditioning system, affecting respiratory health. It's recommended to temporarily secure it with tape to prevent shaking and then visit a professional repair shop as soon as possible. They can check if the entire ceiling frame is loose to prevent similar incidents. Safety first—don’t delay, especially if you have children at home. Address hazards promptly to ensure safe driving. Prolonged high temperatures can also accelerate glue failure, so try to park in the shade to extend the lifespan of your interior.

It's best to have the sagging car headliner fixed by a professional repair shop rather than attempting a DIY fix. They use specialized adhesives and tools to thoroughly clean and re-bond or replace the fabric in one go, ensuring a secure fit. The cost varies from 200 to 700 RMB depending on the size of the affected area, but it's worry-free and safe. Remember to choose a reputable shop to avoid substandard materials and rework.
