Windshield damage comes in many forms, and each type affects your visibility and safety in different ways. Identifying what you’re looking at helps you understand whether a simple repair will solve the problem or if a full replacement is the safer choice. This guide explains the most common types of windshield chips and cracks, how they form, and what to do next.
Most windshield damage falls into a few categories including chips, impact breaks, long cracks, edge cracks, and combination breaks. Smaller chips are often repairable, while long or spreading cracks usually require replacement. If you are unsure which type you have, a professional inspection is the best way to protect your visibility and the structural strength of your windshield.
Damage Types
1. Star Break
A star break has a central impact point with thin cracks that spread outward like the legs of a star. These breaks happen when a rock or piece of debris hits the glass with enough force to create multiple, small fractures.
Repair or Replace?
Star breaks are repairable if addressed early. Once the legs begin to grow, the damage
becomes harder to stabilize.
2. Bullseye Chip
A bullseye chip is a circular, cone-shaped break with a distinct center. It is one of the most recognizable types of windshield damage and is typically caused by a direct hit from road debris.
Repair or Replace?
Bullseye chips are straightforward to repair when caught early. If the diameter becomes too
large, repair might not restore full clarity.
3. Half-Moon (Partial Bullseye) Chip
This break looks like a semi-circle rather than a full circle. It often occurs when debris hits the windshield at an angle rather than straight on.
Repair or Replace?
Half-moon chips are generally repairable but can be more challenging because the impact
pattern is uneven.
4. Long Crack
A long crack is a fracture that extends several inches from the point of impact. These cracks typically spread across the glass over time and can grow due to heat, pressure, or normal driving vibrations.
Repair or Replace?
Long cracks are usually not repairable. If the crack is longer than a few inches or reaches the driver’s line of sight, a full windshield replacement is the recommended solution.
5. Edge Crack
Edge cracks begin within about two inches of the windshield’s outer edge. They can form from impact, but they are also associated with stress from improper installation or weakened glass bonding.
Repair or Replace?
Edge cracks spread quickly because the edge of the windshield experiences more pressure
than the center. Most edge cracks require replacement.
6. Stress Crack
A stress crack appears without any visible impact point. These cracks happen because of sudden temperature changes, manufacturing pressure, or structural stress on the vehicle.
Repair or Replace?
Stress cracks often start small but can grow rapidly. Depending on their length and location, some are repairable, but many require full replacement.
7. Edge Crack
A combination break includes more than one type of damage, such as a bullseye chip with star-like cracks radiating outward. These occur from high-force impacts and are more
complex to repair.
Repair or Replace?
Whether a combination break is repairable depends on its size and how many fractures are
involved.
What To Do If You’re Not Sure What Type You Have
If a chip or crack looks unusual, spreads, or distorts your visibility, do not wait. Early evaluation prevents minor damage from turning into a full replacement.

Frequently Asked Questions
Which types of chips are usually repairable?
Star breaks, bullseye chips, half-moons, and some small combination breaks are often repairable if they are caught early.
When does a crack mean I need a full replacement?
Long cracks, edge cracks, stress cracks, or any damage that enters the driver’s main line of sight typically require replacement.
How do I know if my windshield damage will spread?
Damage near the edge, cracks with multiple legs, or chips exposed to temperature changes are the most likely to worsen.
Does the type of damage affect my visibility?
Yes. Even small chips can distort light, while long cracks or multiple fractures can reduce clarity and create glare.
Can Speedy Glass inspect the damage for me?
Yes. A technician can identify the type of windshield damage and recommend whether a repair or replacement is the safest choice.
