What are the causes of car roof noise?
2 Answers
The causes of car roof noise are: 1. Insufficient assembly force; 2. Noise caused by friction between components; 3. Friction between steel plates due to desoldering; 4. Poor fixation inside the roof; 5. Noise from door hinges; 6. Noise from sealing strips; 7. Noise from interior panels. The method for cleaning the roof is: 1. Fold down the seats, cover them with a towel or seat cover, and use a high-power vacuum cleaner and brush to clean the interior roof, removing easily detachable dust and dirt from the surface; 2. Spray neutral foam cleaner on the fabric surface of the interior roof, wait a few minutes, then use a dedicated cleaning soft brush or a wrung-out car cloth to repeatedly wipe; 3. Use a clean cotton cloth to smooth the fabric in the direction of the interior roof's nap, restoring it to its original condition.
The roof of my car sometimes rattles on bumpy roads, which is quite annoying. After pondering over it multiple times, I suspect the main reason is the small clips inside the roof becoming loose—this tends to happen as the car ages after a few years. Material issues can also be a factor, such as the foam layer beneath the roof's fabric aging and cracking, causing friction noises when driving over bumps. Another common spot is near the sunroof, where loose tracks or screws can lead to vibration echoes. I've tried checking it myself by gently pressing different parts of the roof to listen for sound changes; if a particular area makes more noise, that’s likely the problem spot. The solution is to visit a repair shop to reinforce the clips or replace the material components, and avoid rough handling of the roof during car washes. Ignoring it can worsen the issue, eventually causing the roof to sag.
