Your auto glass does more than protect you from bugs and road debris; it also helps maintain the structural integrity of your vehicle. Because of this, a cracked windshield should always be a high priority to repair. Flying rocks aren’t the only items that can damage your windshield. Stress cracks are another common issue to watch out for. Here’s what you need to know about them.

What Are Stress Cracks?

A stress crack is any fissure that forms in auto glass for a reason other than an impact. Extreme temperature change is the most common culprit. For example, these flaws often form after dousing the windshield with cold water after the car has been sitting out in the sun, or using hot water to try to melt ice from the windshield. Structural defects can also cause stress cracks to form, most often around the edge of the windshield. This occurs when uneven pressure is applied when installing a windshield, or when residual stresses are not properly addressed during the manufacturing process.

How Are These Cracks Repaired?

The windshield repair process for stress cracks is similar to other auto glass repairs. A technician inspects the fracture to determine if they can repair it or if they need to replace it. They fill repairable cracks with a specialized resin that stabilizes the glass and keeps the crack from growing.

However, because stress cracks typically start at the edge of the windshield and grow large quickly, they typically result in a windshield replacement. A repair would not fully address the structural hazards that occur after a large fissure forms.
