Common causes of interior vehicle leaks

Nobody wants to sit in a leaky car, with water dripping through. But why do water leaks occur? And what can you do to fix them, and prevent them? Well, here at Red Rose Windscreens, we are Preston’s leading windscreen professionals. We repair and replace windscreens for a variety of vehicles including classic and vintage cars, as well as trucks and camper vans. As a result, we have produced this guide to the common causes of interior vehicle leaks

Common causes of interior vehicle leaks

Water leaks inside your car are often caused by faults in the:

  • sunroof membrane
  • windscreen membrane
  • door seals

Sunroof membrane

The sunroof membrane lines the glass of the sunroof and the opening in the vehicles roof. But unfortunately, the seal itself is not usually 100% waterproof. Instead there is a small channel around the aperture which allows water to flow down drain tubes either mounted in some, or all of the corners. If these drain tubes become clogged or full, the water will not drain effectively, and instead will drip through the sunroof membrane, causing a small amount of water to build up.

Windscreen membrane

Water can also seep into your car through faults in the windscreen membrane. Over time, and with regular driving, the windscreen rubber can become eroded and this leaves small gaps around the windscreen itself, where water can leak into your car. This can easily be fixed with a new seal.

Door seals

The rubber seal around the edge of the door can also cause of leaks. The seal can become damaged over a period of time, or it can be damaged by water. Once the seal is damaged, the water will track down the front of the door and into the car. A visual inspection is usually sufficient to diagnose whether it’s the culprit.

If you are concerned about water ingress, or have noticed damage to your seals or roof, take action today. Water ingress can cause many problems: the earlier it is treated, the better. Contact the professionals at Red Rose Windscreens today.
