What are the Common Causes of Rear Windshield Glass Damage?

The rear windshield glass is one of the most vulnerable components of the vehicle, as it is susceptible to many types of damage. The rear windshield can be subject to various damaging forces, from small chips and cracks to full breakage. Understanding the common causes of rear windshield glass damage can help drivers take the necessary steps to protect their vehicles.

The Common Causes of Rear Windshield Damage

Stones and Debris hitting the windscreen 

One of the most common causes of rear windshield damage is stones and other debris that are kicked up on the road. When a car drives over a rough surface, small stones and other particles can be thrown up at high speeds and hit the rear windshield. The force of the impact can cause cracks or chips in the glass, which can quickly spread and become a larger problem.

Extreme Temperatures

Extreme temperatures can also cause rear windshield glass damage. When temperatures are too hot or too cold, the glass can expand, contract, and eventually crack or chip. Extreme temperature changes can also cause the windshield to become brittle, which can make it even more susceptible to damage.

Car Accidents/Collisions

Car accidents and collisions are the leading causes of back windshield damage. Rear windshield glass can become damaged in any type of accident, from a minor fender bender to a major multi-vehicle pileup.

In a rear-end collision, the impact of the accident can cause the rear windshield to crack or shatter. This is because the force of the impact is greater in the rear of the vehicle, as opposed to the front. The glass may also become dislodged from its frame due to the force of the impact.

Poor Installation 

Poor installation is another common cause of rear windshield glass damage. Poorly installed windshields can be prone to air and water leakage, which can cause the glass to separate from the frame. 

What To Do To Prevent Rear Windshield Damage

The best way to protect rear windshield glass from damage is to maintain a safe distance from other vehicles on the road and avoid driving over rough surfaces. Additionally, it is important to inspect the glass regularly for any small chips or cracks and have them fixed by auto glass professionals as soon as possible to prevent further damage.
