Can a Chip Weaken the Integrity of Your Windshield?

Last updated 6 years ago

You’ve had that pesky little chip in your windshield for several weeks and months, but you still haven’t contacted an auto glass repair service to fix it yet. Although that little chip may seem harmless, small chips are actually known to cause serious safety issues related not only to the strength of your windshield, but also to the strength of your vehicle. Here’s a look at how that little chip could mean big trouble for your windshield and your vehicle.

Chips in your windshield are usually caused by small bits of road debris, such as rocks or asphalt. These chips typically occur in the outermost layer of glass on your windshield, but aren’t able to permeate the protective plastic sheet and interior glass portions of your windshield. Because drivers can’t feel the crack on the interior of the windshield, most shrug it off as a minor cosmetic issue.

However, chips in the windshield’s exterior can dramatically weaken the strength of its entire structure. As your windshield expands and contracts with changes in the temperature, your small chip will slowly expand into a large crack that may span throughout the entire top layer of the windshield. These cracks weaken the strength of this top layer of glass, which can make the rest of your windshield more susceptible to damage.

A chipped windshield can also weaken the rest of your vehicle. In most modern cars, windshields are designed to act as part of your vehicle’s crumple zone. If your vehicle gets into a wreck, a strong windshield can help to alleviate some of the energy on the front end of the vehicle, which keeps the cabin safer. The weaker the windshield, the more of that energy will enter the cabin where you and your passengers are.

If you have a chip or a crack—or need a whole new windshield—we can help. For expert mobile windshield repair services in the Oakland area, contact Glass on the Move today by calling (510) 338-4791.
