Should the falling fabric of a car's roof liner be repaired or replaced with new fabric?
2 Answers
It is common for the interior roof lining of older cars to fall off. It is recommended to go to professional automotive upholstery shops for repair, refurbishment, or replacement. Reasons for the roof lining falling off: The reason is that the sponge layer inside the roof fabric has detached from the adhesive layer over time, or it can be said that the sponge has deteriorated due to the chemical effects of frequently used cleaning agents. Function of the car roof fabric: The car roof fabric is an important component of the vehicle's roof lining. Its main function is to enhance the interior decoration while also improving the insulation and heat resistance effects between the interior and exterior of the car. It reduces interior noise and improves sound absorption, thereby enhancing passenger comfort and safety.
Last time my car's headliner fell down, I was torn for a long time. I first tried spraying adhesive to stick it back myself, but ended up using the wrong ordinary glue—not only did it fail to hold, but it also corroded the foam layer. Later, I consulted a professional technician who told me that small areas of detachment could be spot-repaired, but if the detached area exceeded 30% or if the foam layer felt brittle to the touch, the entire headliner would need replacement. My car was six years old at the time, so I simply spent over a thousand to replace the entire headliner fabric. It’s been two years now, and it’s holding up perfectly. For a newer car, spraying specialized adhesive and pressing it flat might suffice—the key is to address the issue early, otherwise, moisture absorption during rainy days makes it even harder to salvage.
