Why Is Water Leaking Into Car From Roof?

While the number of cases is limited, that doesn’t imply that they cannot be severe. It is also not wrong to mention that finding the leak in the roof is not always the easiest one to find as you will probably notice water collected at the lowest part of your car’s floor, that is when you see water leaking into the car when it rains.

In such a case, spotting the exact location or I should say locations of damage can be quite a problem. Some may even ignore it assuming it entered via windows, windshield, or door. Hardly will anyone doubt the roof until severe damage.

A sunroof can be sometimes damaged by default while manufacturing or in other cases when something heavy hits the car from above so that a dent is formed. This dent later with time may convert into a notorious tiny hole. The leaks by design are not your fault but the factories. Most of the manufacturers use low grade waterproofing or sometimes completely do not use one at all.

To make sure that the culprit of the mess caused is hidden in the roof and nowhere else, just manually pour some fluid(probably liquid or rubbing alcohol) into the drain tube and top of your car. Did the water flow away straightly in no time? Or does it flows away but at a delayed rate? Maybe it does not flow at all and is stuck there? Well, your culprit lies in one of these options.

How To Repair Water Leaking Into The Car?

After pondering for a while on potential reasons, it is now time to find a cure rather than driving while floating in a half-filled car! Let us now discuss some of the solutions available for this blunder.

The most important one is preventing damage from happening in the first place rather than finding a cure for it. You should avoid loading heavy stuff on your car’s roof.

They are usually located where water accumulates easily. Remove the contaminants and debris found. Small cracks and dents, and old and rusted parts are mostly responsible for future leaks.

Wipe the area with a cotton swab dipped in rubbing alcohol and let it dry. Purchase a new high-quality roof sealant from the market yourself. You can find it easily in a decent hardware store. After cleaning, use a considerable amount of sealant to seal the gap completely. Leave it to dry naturally for around half an hour.

TADAA! you are good to go now.

Above were steps you need to follow in case you decide to repair the leak yourself. But if your car was damaged by default or it is still under warranty, then do not hesitate to contact customer care. If you are eligible, you can get professional help for free or at most for the least price.
