What Causes Roof Leakage in Cars?

[DeIvan]

Here are the specific reasons for roof leakage in cars: 1. Failure of floor grommets: There are several holes on the floor panel. When the grommets embedded from above become misaligned, the interior of the car becomes directly connected to the ground. During heavy rain, water can seep in from below. Lift the floor mat to expose the grommets. If the grommets fall off, water will enter the car from the road surface. 2. Clogged drainage pipes: Blockage of the drainage pipes under the front windshield is the most common cause of water leakage inside the car. This often occurs when the vehicle is not cleaned regularly or is parked under trees for long periods, allowing dust, leaves, mud, and other debris to be washed into the drainage pipes by rainwater.
