What causes a leaky roof? What to do if the roof is leaking

Roof leakage is likely to be caused by the aging of the sunroof sealant, and it may also be caused by the aging of the sealant strip on the top of the car, which requires the owner to replace the sealing strip in time.

If it is a car sunroof leakage, the first thing to check is the sunroof drainage hole, you need to check whether the sunroof drainage hole is blocked, if the sunroof drainage hole is blocked, it can be solved by cleaning it in time, if it is the sunroof sealing strip aging phenomenon, it is recommended to replace the sealing strip in time.

The drainage performance of the sunroof track is generally excellent, which can ensure that the roof water is drained away in time, if the rain is too heavy, the sunroof water is more serious, in this case, the sunroof track should be cleaned up in time to avoid the dust on the sunroof track from accumulating on the sunroof track.

It is recommended that the owner do not open the sunroof frequently in the process of using the car, the existence of the sunroof is to make the people in the car more breathable in the process of driving the car, if the sunroof is frequently used to open and close the sunroof, it will lead to the phenomenon of sunroof damage, and it will also shorten the service life of the sealant, so it is necessary to use the sunroof reasonably.

Check the drain pipe mouth in the front of the sunroof, and then check the lower pipe mouth, the end of the front two drain pipes is at the junction of the front windshield and the hood, open the hood and you can see it from the position of the bracket, find a mineral water bottle to connect the water to the drain pipe to the sunroof to check it, the drain pipe is blocked, the water can't go down, and the water is dangling when driving, and it will go to the glasses case.

Treatment of roof leakage:

1. Check the sealing strips on both sides of the sunroof and the top of the car, and replace them according to the situation.

2. Check whether the drainage pipe is blocked, clean the pipe regularly, and check for damaged parts.

3. Check whether there is a crack on the top of the car, and if there is, you need to go to the repair shop for maintenance.

There are several reasons why a roof leaks:

1. Skylight leakage: There are generally two situations of skylight leakage, one is that there are some small sand particles and dust in the skylight drainage groove, which causes it to be blocked; Second, the sunroof sealant strip has been "lifted" and displaced. Therefore, you should regularly clean the skylight to keep the area around the drain tank clean, and don't forget to use high-pressure jet equipment to do jet treatment in the direction of the drainage pipe when washing the car, and try to blow off the dirt in the pipe.

2. Failure and rain leakage of automobile waterproof adhesive: rain leakage usually occurs at the switch of the door and luggage compartment, and most of the reasons for this happen are the waterproof strip, that is, the defective, old, aging or fracture of the plastic waterproof strip, and the rainwater will soak in from there. Rebonding with a special adhesive for waterproof strips can completely prevent water leakage.

If rainwater leaks from around the door, the cause is mostly the waterproof strip pasted around the door, check for breakage and peeling. The inlaid strips around the doors are easy to deflect, so if rain gets into the car, check the door strips first. If the door strip comes loose, it can be re-applied with a special adhesive to restore the sealing properties so that it will not leak again.

3. The drainage pipe is blocked and causes water leakage in the car: the drainage pipe blockage under the front windshield is the most common situation of water leakage in the car, the vehicle is often not cleaned, and the permanent parking under the tree will lead to dust, leaves, mud and other debris being washed into the drainage pipe by the rain, and over time it will block the pipe, resulting in poor drainage, and the rainwater will naturally flow back into the car during the rainstorm, resulting in water leakage. Therefore, it is necessary to clean the pipes regularly and check for damaged parts.

Roof leakage, if the car has a sunroof, it is likely that the sunroof drain pipe is blocked or the rubber ring of the sunroof is not well sealed, it is recommended to check whether there is a problem in these two places.

This is the case when a skylight leaks and kills you.

First of all, you need to determine the cause of the roof leakage. If the sunroof seal is aged, we can repair it by replacing the window seal, if the drain hole is blocked, then you can find the sunroof drain hole to clean the sunroof flow tank for foreign matter and dirt treatment. If the roof is cracked and the water leaks, it is recommended to apply sheet metal painting.

Causes of car visor leakage.

A leak in the sun visor is most likely caused by a clogged roof deflector or water deflector, with a blocked deflector under the front windshield being the most common problem.

2. When washing the car, avoid using a high-pressure water gun to shoot directly at the sealing ring, which will deform the sealing ring.

3. Clean the dust and leaves in the drainage holes and grooves in time to avoid the blockage of the drainage holes or the reduction of the performance of the sealing ring.

4. Apply lubricating oil regularly to reduce the wear of the window rail and prolong the life of the skylight.
