Will a Loose Roof Drainage Channel Trim Cause Leakage?

[ElenaLynn]

Roof drainage channel trim being loose will not cause leakage. The specific reasons for roof leakage are as follows: 1. Sunroof leakage: There are generally two situations for sunroof leakage. One is that small sand particles or dust in the sunroof drainage channel cause blockage; the other is that the sunroof sealing strip is lifted or displaced. 2. Waterproof adhesive failure: Leakage usually occurs at the openings of doors or the trunk, mostly due to poor, aged, or broken rubber waterproof strips. 3. Clogged drainage pipe: The most common cause of interior leakage is the blockage of the drainage pipe under the front windshield. Not cleaning the vehicle regularly or parking it under trees for extended periods can lead to debris such as dust, leaves, and mud being washed into the drainage pipe by rainwater.
