A rock pings off a dump truck on I-285 and leaves a mark on your windshield. Maybe you noticed it pulling out of your driveway in Decatur this morning - a small circle with tiny lines radiating from the center. Or maybe it is a thin line running sideways across the passenger side. Either way, you are wondering: is this something I need to fix right now, or can it wait?
Knowing how to identify the type and severity of windshield damage helps you make smart decisions fast. Some damage can be repaired in 20 minutes at a fraction of replacement cost. Other damage demands a full new windshield before you get back on the highway. This guide walks you through each type of damage, explains what to look for, and tells you when to call a professional.
Why identifying damage early matters
Your windshield is not just a wind barrier. It is a structural component that contributes up to 30 percent of your vehicle’s roof strength in a rollover and supports proper airbag deployment on the passenger side. Driving around Atlanta on I-75, I-85, or GA-400 with unaddressed damage puts you and your passengers at risk.
Early identification also saves money. A small chip that costs $50 to $80 to repair can turn into a full-length crack that requires a $300 or more windshield replacement - especially during Georgia’s hot summers when temperature swings stress damaged glass.
Types of windshield damage
Chips
Chips are the most common form of damage. They happen when a small, hard object - typically gravel, a pebble, or road debris - strikes the windshield at speed. Atlanta’s ongoing highway construction along I-285 and the Downtown Connector makes chip damage especially frequent.
How to identify a chip:
- Small, localized impact point - usually less than one inch in diameter
- May appear as a single divot (called a “bullseye”) or a small starburst pattern
- Often has a visible center point where the object made contact
- The surrounding glass remains intact and smooth
Common chip types:
| Type | Appearance | Repairability |
|---|---|---|
| Bullseye | Circular, cone-shaped divot | Almost always repairable |
| Half-moon | Semi-circular chip | Usually repairable |
| Star break | Short cracks radiating from center | Repairable if under 3 inches total |
| Combination | Mix of star and bullseye | Depends on total size |
| Bee’s wing | Chip with two cracks at angles | Usually repairable |
Key rule: Most chips smaller than a quarter (about 1 inch) qualify for a quick resin repair rather than a full replacement. If you spot one, schedule a windshield repair sooner rather than later - Georgia’s heat and humidity accelerate crack spreading.
Cracks
Cracks are lines that extend through one or more layers of the windshield. They can start from a chip that was left unrepaired, or they can appear on their own from stress.
How to identify a crack:
- A visible line running through the glass
- Can be straight, curved, or branching
- May start at the edge of the windshield or radiate from an impact point
- Feels like a groove or ridge when you run a fingernail across it
Crack categories by length:
| Length | Assessment | Typical action |
|---|---|---|
| Under 6 inches | Often repairable if not in the driver’s direct line of sight | Resin injection and UV cure |
| 6-12 inches | Borderline - depends on location and depth | Professional evaluation needed |
| Over 12 inches | Not repairable | Full windshield replacement |
| Edge-to-edge | Structural compromise | Immediate replacement |
Stress cracks deserve special mention. These appear without any visible impact point - the glass just develops a line, usually starting at the edge. They are caused by temperature fluctuations (a frozen Atlanta morning followed by a 60-degree afternoon), manufacturing defects, or frame pressure from a minor fender bender. Stress cracks are not repairable and always require replacement.
Scratches
Scratches can be caused by worn wiper blades, improper cleaning tools, or fine debris dragged across the glass surface. Atlanta’s notorious pollen season can contribute to scratching when drivers wipe caked-on pollen with dry towels or run wipers without fluid.
How to identify scratches:
- Thin, shallow marks that may only be visible under certain light angles
- Often follow the arc pattern of wiper blades
- Do not have a central impact point
- Feel smooth to the touch but catch light differently than surrounding glass
Minor scratches rarely require replacement, but deep or widespread scratching reduces night visibility by creating halos and glare around headlights. If scratches affect your ability to drive safely after dark, it is time for new glass.
Pits
Pits are tiny craters in the glass surface caused by sand, grit, and small particles hitting the windshield over time. Drivers who commute daily on I-75 through the construction zones south of Downtown Atlanta or along I-85 through Gwinnett County often accumulate pits faster.
How to identify pits:
- Very small, shallow divots scattered across the glass
- Most visible when driving into direct sunlight (a common problem during east-bound morning commutes and west-bound evening commutes on I-20)
- Individual pits are too small to repair, but collectively they reduce clarity
- The glass may look hazy or frosty in bright light
When pitting becomes widespread enough to affect visibility, windshield replacement is the only effective solution.
How to inspect your windshield
Regular self-inspections catch damage before it spreads. Here is a simple four-step process:
Step 1: Visual scan from outside
Walk around to the front of your vehicle and look at the windshield from several angles. Tilt your head to catch light differently. Fresh chips are easiest to spot when the sun reflects off the glass at a low angle - early morning or late afternoon light works best.
Step 2: Run your fingertips across the glass
Gently slide your fingers across the exterior surface. Chips and cracks have a detectable ridge or depression. Do not press hard, and be careful around visible damage to avoid cuts on exposed glass edges.
Step 3: Check from the driver’s seat
Sit in the driver’s seat and look through the windshield at a plain background - a clear sky or a blank wall works well. Any distortion, fogging between glass layers (delamination), or obstructions in your normal line of sight need attention.
Step 4: Inspect edges and corners
Cracks that start at the windshield edge are the most dangerous because they compromise the bond between glass and frame. Look carefully along all four edges where the glass meets the trim. Use a flashlight at night to illuminate hidden edge cracks.
Repair vs. replacement: A quick decision guide
| Factor | Likely repairable | Likely needs replacement |
|---|---|---|
| Size | Chip under 1 inch, crack under 6 inches | Chip over 1 inch, crack over 6 inches |
| Location | Away from edges, outside driver’s direct sight line | At the edge, in driver’s line of sight, or over ADAS camera |
| Depth | Surface layer only | Penetrates inner laminate layer |
| Number | 1-3 isolated chips | Multiple cracks or widespread pitting |
| Age | Fresh, clean damage | Old damage with dirt or moisture inside |

Why Atlanta drivers face higher windshield damage risk
Several factors make the Atlanta metro area tougher on windshields than many other cities:
- Heavy highway construction - Ongoing projects on I-285, I-85, and the Downtown Connector throw loose gravel and debris into traffic daily.
- Temperature swings - Winter mornings in the 20s followed by afternoon highs near 60 create thermal stress that expands existing damage.
- Pollen season - Heavy pollen accumulation leads to aggressive wiping and cleaning, which can scratch the glass or reveal hidden chips.
- Hail events - Spring and summer thunderstorms occasionally produce hail that can crack or pit windshields across entire parking lots.
- High traffic density - More vehicles on the road means more debris kicked up, especially on high-speed stretches of GA-400 and I-75.
What to do when you find damage
- Do not ignore it. Even a small chip can spread into an unrepairable crack within days during a Georgia summer.
- Cover the damage temporarily. A piece of clear packing tape over a chip keeps moisture and dirt out until you can get it repaired. Do not use anything adhesive directly on cracks.
- Avoid extreme temperatures. Do not blast hot air from the defroster onto a cold, damaged windshield. The sudden temperature change can cause a chip to spider into a crack.
- Call Glass Inc. We offer free inspections and same-day windshield repair for most chip and crack types. If replacement is needed, our auto glass service team can typically install new glass the same day.

Frequently asked questions
Can a windshield chip be repaired, or does the whole windshield need to be replaced?
Most chips smaller than a quarter and cracks shorter than six inches can be repaired with resin injection. Damage in the driver’s direct line of sight, at the windshield edge, or over an ADAS camera usually requires full replacement.
How long can I drive with a chipped windshield?
It is safest to get chips repaired within a day or two. In Atlanta’s heat, a chip can spread into an unrepairable crack quickly. If you must drive, avoid pothole-heavy roads and sudden temperature changes until you get the repair done.
Does insurance cover windshield chip repair in Georgia?
Many comprehensive auto insurance policies in Georgia cover chip repairs with no deductible. Glass Inc handles insurance paperwork for you - call us at (404) 873-6991 to verify your coverage.
How do I tell the difference between a stress crack and an impact crack?
Impact cracks have a visible point of contact - a chip, starburst, or bullseye at one end. Stress cracks appear as a clean line with no impact point, usually starting from the windshield edge. Stress cracks cannot be repaired and always need replacement.
What happens if I ignore a windshield crack?
The crack will spread due to road vibration, temperature changes, and wind pressure. Eventually the windshield loses structural integrity, which affects airbag deployment, roof strength in a rollover, and your ability to see the road clearly. Georgia state inspection also considers windshield condition.
