As a driver, chances are you’ll deal with windshield damage at some point. Whether it’s a flying rock or a sudden shift in temperature, cracks can appear without warning. Understanding the different types of windshield cracks can help you make informed decisions about whether you need a repair or full replacement.
At our auto glass shop, we provide expert windshield repair in Toronto, and we’ve seen every kind of damage you can imagine. This blog explains to you some of the most common windshield crack types that will help you get them resolved at the earliest and efficiently.
What Causes Windshield Cracks?
Windshield cracks usually result from two main causes: impact damage and non-impact damage.
- Impact damage: When an object — like gravel, road debris, or hail — strikes your glass.
- Non-impact damage: Caused by sudden temperature changes, poor installation, or normal wear and tear over time.
Both can lead to different crack types. Understanding your damage helps determine if you need a quick windshield chip repair in Toronto or a full replacement.
Even small cracks can quickly become a serious safety hazard — as we explain in 5 reasons why you shouldn’t ignore your car’s damaged windshield.
Most Common Types of Windshield Cracks
Star Break
A star break looks just like it sounds: a central point with cracks that radiate outward like a star. It usually results from a strong impact, such as debris hitting your windshield at high speed.
These cracks can spread quickly and weaken the structural integrity of your glass. That’s why we recommend getting them looked at right away. Repairing a star break early can stop a windshield crack from spreading and prevent the need for a full replacement. Our windshield chip repair service in Toronto can handle star breaks quickly before they worsen.
Bull’s Eye Crack
A bull’s eye crack is round with a central pit. It’s one of the most common cracks we see during auto glass repair in Toronto. This damage is usually caused by a rock or hard object striking the glass directly.
Bull’s eye cracks can often be repaired easily if addressed early. However, if left too long, they may spread or deepen, requiring more complex work or a replacement.
Half-Moon Crack
The half-moon crack is similar to a bull’s eye, but not perfectly round. It’s usually caused by debris striking the windshield at an angle, which creates a curved or oval-shaped break.
These cracks are typically repairable, especially if they are small and don’t obstruct your view. Our team will assess the damage and recommend the best solution.
Minor Chips
Minor chips are small, often caused by stones or gravel, and are one of the most manageable forms of windshield damage. The urgency of repair depends on the chip’s location and size.
If a chip is located in the center of your windshield or is starting to spread, you should schedule a windshield chip repair in Toronto as soon as possible. Otherwise, it might turn into a larger crack and become harder to fix.
Combination Break
A combination break includes two or more crack types in one area—like a bull’s eye crack with lines spreading outward, or a star break with a long crack forming.
Combination breaks can be more difficult to repair, especially if they affect the driver’s view. In such cases, we strongly recommend scheduling a professional inspection to determine if a repair is possible or if replacement is necessary.
Long Crack
A long crack extends over 15 cm and usually starts from a small chip or edge crack. These are often caused by temperature extremes or high stress on the windshield.
Because of their length, long cracks are difficult to repair. Most of the time, this damage requires full windshield replacement, especially if it affects visibility or continues to spread.

Edge Crack
Edge cracks begin within two inches of the windshield’s outer edge. They usually result from pressure around the windshield frame, poor installation, or thermal stress.
Edge cracks tend to spread quickly, and if ignored, they can lead to complete windshield failure. If you notice an edge crack, schedule an inspection with our team right away to prevent further damage.
Stress Crack
Stress cracks appear without any direct impact. They’re often caused by environmental pressure, age, or temperature fluctuations. These cracks can develop slowly and suddenly become a serious safety risk.
If you drive an older vehicle or suspect a stress crack is forming, a quick inspection from our team will determine the best next step.
