Ontario drivers face some of the harshest weather in Canada, from freezing winters to humid summers. These temperature swings can seriously impact your windshield and auto glass. Understanding how weather affects your vehicle helps you prevent damage and stay safe on the road.
At Dixie Auto Glass, we have helped thousands of drivers protect and repair their auto glass in every season. Here is what you need to know.
Why It Matters
According to Transport Canada, weather-related auto glass damage is one of the top reasons for windshield replacements in Canada. GlassBYTEs also reports that untreated chips are much more likely to spread when temperatures rise or fall suddenly.
Knowing how to care for your glass in all conditions can help you avoid expensive repairs.
How Winter Weather Affects Auto Glass
- Thermal Stress: When you blast the defroster on a cold windshield, the rapid change in temperature can make chips expand into long cracks.
- Ice Scraping: Scrapers can scratch the surface and weaken the glass.
- Heavy Snow: Weight and pressure can worsen existing damage.
- Road Salt: Salt residue can corrode seals and edges over time.
How Summer Heat Affects Auto Glass
- Expansion: Glass expands in high temperatures, which can enlarge small cracks.
- UV Damage: Prolonged sun exposure weakens the structural integrity of the windshield.
- Sudden Cooling: Spraying cold water on hot glass can cause it to fracture.
Step-by-Step: How to Protect Your Windshield Year-Round
- Use a Windshield Cover: Protects against ice buildup and reduces heat in summer.
- Warm Up Gradually: Avoid blasting heat directly on frozen glass.
- Park in the Shade: Prevents UV damage and thermal stress.
- Repair Chips Early: Small damage is more likely to spread during temperature swings. Our stone chip repair service can help stop cracks before they grow.
- Clean Regularly: Remove salt, dirt, and debris to prevent corrosion.
