Hailstorms are unpredictable and often destructive. One of the most common questions people ask after a storm is: Can hail break windows? The short answer is yes—but it depends on the size of the hail. In this guide, we’ll break down what hail size causes window damage, how to prevent it, and what to do if it happens to your car or home.
How Big Does Hail Need to Be to Break a Window?
Most windows, including those in cars and homes, can handle small hail. But once hailstones reach 1 inch in diameter (about the size of a quarter), they can crack, chip, or even shatter glass. The larger the hail, the greater the impact. Wind speed and the age or condition of the glass also play major roles in whether it holds up or fails.
What Size Hail Can Break Windows? Find Out Now
Hailstones that are 1 inch or larger are strong enough to break standard glass. At 1.5 inches, many car side windows or older home windows are at serious risk. If the hail reaches 2 inches or more, even laminated or double-pane glass may not survive the hit.

Can Hail Break Windows
Size isn’t the only factor. Wind-driven hail hits harder and faster. Older or damaged windows are more likely to break—even with smaller hailstones. So, if your windows already have chips or wear, your risk increases.
Which Windows Are Most Vulnerable?
Certain types of glass are more at risk during a hailstorm. Here’s what you should know:
Vehicle Side Windows: These are usually tempered glass, which breaks into small pieces on impact. Easier to break than windshields.
Windshields: Made of laminated glass. Stronger than side windows but can still crack.
Home Windows: Older, single-pane windows are weak against hail. Newer, double-pane versions offer better protection but are not hail-proof.
Sunroofs and Skylights: These are often made with tempered glass and are highly vulnerable in storms.
If you see any chips, lines, or “spider-web” cracks after a storm, take action quickly.
How to Check for Hail Damage
After a hailstorm, inspect your property or vehicle for signs of glass damage:
Chips or cracks in car windows or sunroofs
Dents on the metal frame near the glass
Loose or broken window seals in homes
Water leaks around windows or windshield
Even if there’s no obvious break, small cracks can expand later—especially in heat or cold. Timely repair can prevent larger problems.
Preventing Window Damage from Hailstorms
Protecting your car and home from hail can save you money and stress. Here’s what helps:
Park Under Shelter: Use a garage, carport, or public covered parking.
Use a Car Hail Cover: These padded covers protect your car windows from sudden impacts.
Check Weather Alerts: Move your car or close window shutters before the storm hits.
Regular Maintenance: Replace old windows or fix small chips before they worsen.
Pro tip: Never park under trees or power lines during a storm—they add even more risk.
What If You Already Have Hail Damage?
Don’t wait. Cracked windows can’t protect you properly. If your car’s windshield or sunroof is hit, the next bump in the road might turn a small crack into a full break.

Does Small Hail Cause Problems Too?
Yes. While it may not shatter glass, small hail (pea to dime-sized) can still leave tiny chips in your windshield or home windows—especially if it’s accompanied by strong winds.
Left untreated, even these chips can grow over time due to vibration, temperature shifts, or pressure from car doors or home shutters. Always inspect your windows after a storm, no matter how minor it seems.
Conclusion
Hailstones 1 inch or larger pose a serious risk to all types of glass—including car windows, home windows, and sunroofs. Even if damage isn’t immediately visible, it’s important to inspect your property after every storm.
If your auto glass has been hit by hail, don’t wait to get it checked. Prompt repairs can prevent further cracking and help keep you safe while driving.
