Common Types of Windshield Rock Chips

Nothing can be more momentarily alarming than hearing a loud ping while driving on the highway and looking up to see a big old rock chip on your windshield. While putting off windshield rock chip repair may seem like a plausible temporary solution, the truth is, the longer you wait to get it fixed, the more problems that could arise further down the road.

It’s also important to know that not all windshield rock chips are the same. In fact, understanding the variations of windshield rock chips can help determine whether minor windshield repair is necessary or total windshield replacement is needed.

Let’s take a look at the common types of windshield rock chips, as well as the most recommended repair options for each one.

Star Chip

Arguably the most common type of windshield rock chip, star chips (or star breaks) get their name from their starburst-pattern shape. They have smaller cracks that protrude from the center of the crack and can easily distort visibility on the vehicle’s windshield.

A star chip on a windshield can be repaired without resorting to windshield replacement, but only if the cracks stemming out from the center are under three inches in length. However, star chips should be repaired immediately, as they can quickly weaken the windshield’s infrastructure.


A bullseye break or chip features an appearance resembling that of the bullseye center of a dartboard. They tend to look like dark-colored circles with several layered rings of cracking inside. Depth depends on the velocity of impact a rock makes upon the windshield.

Bullseye chips are very common and can usually be repaired relatively quickly, as long as windshield repair is applied in a timely manner. Depending on the location of the bullseye chip, as well as the length and width of diameter, windshield replacement might be necessary in extreme cases.

Combination Break

Combination breaks tend to be more severe examples of windshield rock chips. Their size and shape features similarities from both the aforementioned star and bullseye chips, which explains the name.

While windshield replacement may not be necessary in some cases, combination breaks that disrupt the driver’s view will usually require immediate replacement services.

Batwing Chip

Batwing chips occur when a windshield rock chip divides off into two branches of cracks, generally forming a V-like shape that’s similar to that of a bat spreading its wings.

If the length of the two cracks doesn’t exceed three inches, then adequate windshield repair work can take care of it. However, failure to act quickly on batwing chips could result in both cracks increasing and size and further deteriorating a windshield.

Half Moon Chips

A partial bullseye chip with half a circle in the center is commonly referred to as a half moon chip, after its resemblance to a waning crescent moon. These occur when a rock hits the windshield at a peculiar angle, which may lead to further, more extensive cracking if not addressed quickly.

Because of their difficult shape and depth, half moon chips may require windshield replacement, depending on the severity of the damage.
