What Causes Car Roof Lining to Detach?
2 Answers
Car roof lining detachment is caused by adhesive aging. Below are methods for repairing the roof fabric: 1. Edge adhesive failure: Use specialized automotive adhesive or bonding products to spray along the detached area, then let it dry for 3-5 minutes. 2. Central sagging: If the middle section of the roof lining sags or detaches, you can opt for clip repairs by selecting clips of a similar color. 3. Large-area detachment: The entire roof lining must be removed, the old fabric taken off, and the aged sponge surface cleaned. Prepare a new roof fabric and specialized roof adhesive, spray adhesive on both sides, and let it dry for 3-5 minutes before bonding.
I've been driving this car for over ten years and have encountered the issue of the roof lining falling off several times. It's mainly caused by material aging and adhesive failure—the fabric and foam in the roof lining dry out and become brittle over time, and the glue gradually loses its stickiness. Especially when parked outside in the sun, the high temperatures soften the adhesive quickly, making the bonding points prone to loosening. Humid air is also an accomplice, as moisture seeping in can degrade the adhesive, causing the fabric to expand and detach. Once, I used the wrong cleaner on the interior, which corroded the adhesive and caused localized detachment. Pulling too hard during use can also damage the bonding points. My current approach is to pay more attention to maintenance, try to park in shaded areas, and check for roof lining looseness every six months. If any issues arise, I promptly take it to a professional shop for repair—delaying can lead to bigger problems and safety concerns.
