The Top 10 Causes of Windshield Cracks and How to Avoid Them

We empathize with the frustration and safety concerns that arise upon discovering a crack on your windshield. However, you can rest assured knowing that Bama Auto Glass is here to provide you with valuable insights into the top 10 causes of windshield cracks. Our aim is to equip you with practical tips to prevent such incidents from occurring. So, prepare yourself for a journey towards maintaining a crack-free windshield, ensuring a smooth and safe driving experience for you and your passengers.

1. Road Debris and Flying Rocks

When cruising the open road, road debris and flying rocks can take you by surprise and leave behind unsightly chips or cracks on your windshield. To steer clear of this hazard, maintain a safe distance from large vehicles that may kick up debris. Be mindful of gravel roads or areas with loose stones, and if you spot an incoming rock, reduce your speed and maneuver your vehicle away from its path.

2. Extreme Temperature Changes

While we can’t control the weather, we can take steps to protect our windshields from extreme temperature changes. Rapid shifts from scorching heat to freezing cold can put stress on the glass, leading to cracks. Gradually cool your car before cranking up the air conditioning on a hot windshield. And during frosty winters, resist the temptation to use hot water for de-icing, as it can cause sudden temperature changes and cracks.

3. Improper Installation or Repair

Causes of Windshield Cracks

A poorly installed or repaired windshield can make it more vulnerable to cracks. Ensure a job well done by choosing Bama Auto Glass, a reputable auto glass service that excels in proper installation and repairs. Our experienced professionals align windshields with precision and use top-quality materials, reducing the risk of cracks due to shoddy workmanship.

4. Stress from Uneven Pressure

While windshields are designed to withstand pressure, subjecting them to excessive force can result in cracks. Treat your vehicle gently by closing doors with care, and take it easy over potholes and speed bumps. By minimizing undue pressure, you’ll help maintain the integrity of your windshield.

5. Hailstorms and Severe Weather

Mother Nature can be unpredictable, and hailstorms pose a significant threat to windshields. Hailstones falling from the sky can cause extensive damage and cracks. To shield your windshield during severe weather, if possible, park in covered areas. If caught in a hailstorm, seek shelter or park under an overpass until it passes. And if parking options are limited, utilize a car cover or sturdy blankets as temporary protective measures.

6. Neglected Chips and Small Cracks

Small chips or cracks may seem insignificant, but neglecting them can lead to bigger problems. Changes in temperature, vibrations, or subsequent impacts can cause minor damage to worsen over time. To avoid escalation, address chips and small cracks promptly. Contact Bama Auto Glass, a professional windshield repair service, for expert assessment and timely repairs. We’ll save you from the hassle and expense of a full windshield replacement.

7. Avoiding Construction Zones and Rough Roads

Construction zones and rough roads can subject your vehicle to a bumpy ride, increasing the risk of windshield cracks. Whenever possible, steer clear of construction zones or drive cautiously through them. Slow down when encountering uneven or pothole-riddled roads to minimize the impact on your vehicle. Remember, a smooth and steady ride not only protects your windshield but also enhances your overall driving comfort.

8. Avoiding Contact with Harsh Chemicals

Shield your windshield from the damaging effects of harsh chemicals, such as ammonia-based cleaners or abrasive substances. Opt for mild, non-abrasive cleaners specifically formulated for automotive glass. Utilize microfiber cloths or soft sponges when cleaning, and avoid vigorous scrubbing or the use of abrasive materials that can compromise the structural integrity of the glass.

9. Poorly Maintained Windshield Wipers

Windshield wipers play a crucial role in maintaining clear visibility during inclement weather. However, if they’re in poor condition or not properly maintained, they can cause scratches or cracks on the windshield. Regularly inspect your windshield wipers for signs of wear and tear, such as fraying or missing rubber. Replace them as needed to ensure optimal performance. Clean your wipers regularly, and avoid using them on dry glass, as this can lead to unnecessary friction and potential damage.

10. Parking under Trees or Near Construction Sites

While parking under trees offers shade, it exposes your vehicle to falling branches, acorns, or sticky sap that can damage your windshield. Similarly, parking near construction sites increases the chances of debris or construction materials hitting your windshield. Opt for parking spots away from trees with low-hanging branches. When parking near construction sites, exercise caution and choose a spot less likely to be affected by falling debris.


By familiarizing yourself with the top causes of windshield cracks and implementing preventive measures, you can maintain a pristine windshield. Remember to keep a safe distance from road debris, handle your vehicle with care, and seek professional assistance for repairs or maintenance. Trust the experts at Bama Auto Glass to deliver exceptional service and keep your windshield crack-free.
