If you’ve ever driven through Toronto or Richmond Hill, you already know our roads can be unpredictable — from flying debris on Highway 401 to freezing winter mornings that test your patience (and your windshield). Many drivers think the only way a windshield can get damaged is from a rock chip, but that’s just one of many culprits.

At Windshield Experts, we’ve seen just about everything when it comes to glass damage. From the obvious to the unexpected, here are seven surprising ways your windshield can get damaged — and simple steps to prevent it.

1. Flying Debris from Toronto’s Busy Roads

This is the number one cause of windshield damage in Toronto and across the GTA. When trucks or other vehicles kick up gravel, road salt, or loose debris, it can hit your windshield with enough force to create a chip or small crack.

You’re especially at risk on major routes like Highway 401, the DVP, or the 404 — especially during construction season.

How to prevent it:
Keep a safe distance from large trucks, construction vehicles, and salt spreaders. If you can, avoid driving too closely behind them — even small stones can cause serious windshield damage at highway speeds.

2. Sudden Temperature Changes

Toronto and Richmond Hill experience dramatic temperature swings — from hot summer days to icy winter mornings. When your windshield glass expands or contracts too quickly, existing chips can spread into full cracks.

For example, turning on your defroster at full heat on a freezing windshield may cause a small chip to spread instantly.

How to prevent it:
Warm up your car gradually. In winter, scrape off ice manually before turning on the defroster, and avoid pouring hot water on cold glass. During summer, try not to blast cold A/C onto a heated windshield.

3. Improper Car Washing

It might surprise you, but automatic car washes can sometimes cause damage — especially if you already have a chip or weak spot in your glass. The high-pressure jets or spinning brushes used in older wash systems can make cracks spread or create new stress points.

How to prevent it:
If your windshield has any chips, get them repaired before washing. Opt for touchless car washes or hand washes, which are gentler on glass. It’s a small change that helps your windshield last longer.

4. Slamming Doors or Heavy Vibration

Yes — even how you close your car door can impact your windshield. Slamming doors or hitting potholes at high speed (and Toronto has plenty!) sends shock vibrations through the car body. Over time, these vibrations can worsen small cracks or loosen the adhesive around your windshield.

How to prevent it:
Avoid slamming your doors, and drive carefully over rough roads or speed bumps. Regularly inspect your windshield edges to make sure the seal is intact and the glass isn’t shifting.

5. Poor Quality Glass or Incorrect Installation

Unfortunately, not every windshield replacement is done right. Cheap aftermarket glass or rushed installation can lead to problems like poor sealing, leaks, or premature cracking — especially with the road and weather stress of the GTA.

At Windshield Experts, we use only OEM-grade glass and proper installation techniques to ensure safety and durability.

How to prevent it:
Always choose certified technicians for windshield replacement in Toronto or Richmond Hill. A low-cost job might save money now, but could cost much more if it fails later.

6. Tree Branches and Falling Objects

Parking under a tree may seem like a good idea in the summer heat, but falling branches, acorns, or even ice chunks can cause unexpected windshield damage. In Richmond Hill’s residential areas or downtown Toronto, where trees often hang over driveways and street parking, this is a common source of cracks and chips.

How to prevent it:
Whenever possible, park in covered or open areas away from large trees. During storms or heavy winds, avoid parking near construction zones or older buildings where debris could fall.

7. Hidden Structural Stress

Not all windshield damage is visible right away. After a minor accident, your vehicle’s frame may flex or twist slightly — and even small misalignments can put long-term stress on your windshield. Over time, that tension may lead to cracks appearing seemingly out of nowhere.

How to prevent it:
After any collision, even a light one, have your windshield and frame alignment inspected. Our experts at Windshield Experts Toronto and Windshield Experts Richmond Hill can check for hidden stress points and fix any issues before they become major damage.

Small chips might seem harmless, but they’re your windshield’s weak spots. With time, pressure, and temperature changes, they almost always grow into larger cracks.
