Dealing with windshield chips and damage as soon as possible is crucial, as your windshield actually plays an important role in ensuring your safety. Not only do windshields protect you from dirt and debris, but they also account for approximately 45% of the structural integrity of your vehicle’s cabin and around 60% in case of a rollover accident.
Additionally, driving with a cracked windshield can be extremely dangerous. Not only does it compromise your visibility on the road, but it also weakens the structural integrity of your vehicle. A cracked windshield is more susceptible to collapsing upon impact, increasing the likelihood of severe injuries to occupants.
However, it’s important to note that not all windshield cracks can be repaired, as not all windshield chips are the same. There are actually various windshield crack types that your vehicle can incur. Identifying which type of crack you have is important as this determines whether the damage is repairable or not.
Different Types of Repairable Windshield Cracks
When dealing with windshield damage, it’s important to know the difference between a chip and a crack. These terms are often used interchangeably. However, there is a slight difference between them. A windshield chip is more general and is used for smaller damage on the windshield. It is often caused by debris hitting the windshield.
On the other hand, a windshield crack is a distinct line that goes across the windshield and is usually caused by stress on the glass, such as temperature changes.
A small chip can easily propagate into a major crack if not addressed quickly. Unfortunately, as mentioned earlier, not all cracks are repairable.
So, what kind of windshield cracks can be repaired? And how can we identify them? Here’s a helpful guide on the different repairable windshield crack types:
Bull’s Eye Crack
As the name suggests, a bull’s eye crack basically resembles the center of a target. It is a circular chip that is a result of road debris (like pebbles) bouncing off the road and hitting your windshield.
Generally, there is a lower chance of your windshield cracking further when you acquire a bull’s eye crack. However, this type of crack can interfere with the driver’s line of sight and still need to be immediately repaired.
This type of windshield crack is one of the most common and easiest to repair as long as the damage is promptly addressed.
Star Break
Unlike the bull’s eye crack, which only has a single point of impact, a star break also comes from a central point, but the crack spreads outward in multiple directions, making it look like a star.
This type of windshield crack is typically caused by a forceful, high-velocity impact with a sharp or blunt object on the windshield. While minor star breaks can often be repaired, larger cracks pose a significant risk to driver visibility and vehicle safety. In such cases, opting for a windshield replacement is essential to safeguard both your vision and the structural integrity of your car.
Half-Moon Crack
A half-moon crack is an arc-shaped crack that extends from the impact point in both directions. Its crescent shape is the result of a blunt object hitting the windshield at an angle.
The chances of repairing a half-moon crack are higher if they are small, which is why prompt attention is crucial to prevent them from growing into larger, more complex fractures. Otherwise, a windshield replacement may be necessary.
Combination Cracks
As the name suggests, this type of crack is usually a combination of a star break and a bull’s eye crack, making them more difficult to repair.
Rock and stone chips are the usual culprits for combination cracks. The possibility of repairing a combination crack is usually very low unless the damage is less than two inches and if the crack hasn’t spread significantly yet.
Edge Cracks
An edge crack typically starts near the edge and extends inwards, gradually growing longer and deeper as it progresses. This type of crack is commonly caused by stress concentrations or impact, especially in materials like glass or ceramics.
Typically, an edge crack is manageable if it spans less than six inches. However, if it affects the driver’s line of sight, a thorough windshield replacement may be required.
Windshield Cracks That Can’t Be Repaired
It’s important to recognize that not every windshield crack is fixable. If a crack is too severe or if it compromises the structural integrity of the windshield, repair might not be possible. Factors like length, depth, and location determine whether a repair is viable, with replacement being the recommended course of action in some cases.
Here are some cases where a windshield replacement may be necessary:
- Long cracks: Cracks that are too long, typically over 12 inches, may be challenging to repair effectively. The longer the crack, the more difficult it is to prevent spreading and maintain structural integrity.
- Complex cracks: Cracks with complex patterns or multiple intersecting lines may be difficult to repair adequately. These cracks often have varying depths and angles, making it hard to fill them completely and prevent further damage.
- Cracks in critical areas: Cracks that extend into critical areas of the windshield, such as the driver’s direct line of sight or the edges where structural integrity is vital, may not be repairable. Repairing such cracks might compromise visibility or weaken the windshield’s support.
- Contaminated cracks: Cracks that have been contaminated with dirt, moisture, or other substances may not bond properly with the repair resin. In such cases, the repair may not hold, leading to further spreading of the crack.
- Old or previously repaired cracks: Cracks that have been previously repaired or have accumulated dirt and debris over time may not respond well to additional repair attempts. The integrity of the windshield may have been compromised, making further repairs ineffective.
