Posted in Auto Glass Repair, on August 08, 2025
Most drivers and car owners will likely sustain some kind of auto glass damage at some point in their lives. It is perfectly normal and natural to notice small chips and maybe even cracks over time. With that being said, you cannot neglect auto glass repair; instead, you need to be very prompt, as failing to address or even notice glass damage can pose risks to your safety as a driver. Rear auto glass poses the most significant risk because it is often neglected, given how rarely it is inspected by drivers. But being aware of common sources of rear auto glass damage and regularly checking it can help drivers mitigate the dangers of damaged glass early.

Flying Debris from the Road

Flying debris from the road is definitely one of the most common sources of windshield damage, especially to the back of your windshield. As you drive at high speeds, small pieces of debris like pebbles, foliage or even loose trash can get kicked up off the ground by the wheels of your own car or someone else's. Once projected into the air, these items land on the back of your car, leading to you needing auto glass repair. If you notice any random chips or cracks on your back windshield, it is likely from flying debris.
Temperature Fluctuations
Believe it or not, the temperature and weather outdoors can also impact your rear windshield. Glass is susceptible to physical change when subjected to extreme temperatures. For example, when the weather is really hot outside, like during the summer months, your windshield glass will expand. This can weaken the structural integrity of your windshield, making it more susceptible to damage, even if it is subjected to minor physical trauma. Once the temperatures return to normal, your windshield glass will contract back to its original shape, and during the period of contraction, your windshield can crack.
Rear Wiper Blade or Component Failure
As mentioned previously, the rear windshield of most cars is often neglected, as few drivers inspect the back of their car often. Failure to do so may result in you overlooking a damaged rear wiper blade. If a rear wiper blade is misaligned, damaged or has some kind of ice build-up on it in the winter, then it can scratch your windshield while it is in use. If left unattended, these cracks can expand and even shatter if you get into a car collision down the line.
