Windshield repair technology is a rapidly advancing industry, so the ability to repair large chips or cracks changes often and can vary depending on the repair company. Generally speaking, chips smaller than a quarter, and cracks up to three inches long can be easily repaired. The Repair of Laminated Automotive Glass Standard (ROLAGS) guide, administered by the National Windshield Repair Association (NWRA), specifies limits on repair sizes depending on the type of damage (bulls-eye, pit, crack, ect.) with the upper limits of a chip being three inches and a crack up to 14 inches. Again, these sizes may vary depending on the location of the damage, as well as the shop’s capabilities. For more technical specifications, check out the full ROLAGS guide the full ROLAGS guide.
This is closely related to the size of the damage, but in regards to how deep the damage penetrates into the windshield. A windshield is basically a glass sandwich– an outer layer of glass, a plastic interlayer, and an inside layer of glass. If the damage is through the outer and inner layer of glass, it is too deep to perform a windshield repair.
