Understanding the most common causes of winter windshield damage is the first step toward preventing them. Here are the top culprits and what you can do to protect your windshield this season.
1. Temperature Fluctuations
One of the leading causes of windshield cracks in winter is the extreme change in temperature. When you start your car on a freezing morning and crank up the heat, the sudden expansion of the glass can stress existing chips or create new fractures. Windshields are designed to handle stress, but rapid temperature shifts—especially from icy cold to hot—can push them to their limits.
Prevention Tip: Warm your car gradually. Instead of blasting hot air onto the windshield, allow your vehicle to warm up slowly with the defroster on a low setting. This helps reduce the risk of stress cracks caused by thermal shock.
2. Ice Scraping and Improper De-Icing
Using metal scrapers or sharp tools to remove ice can easily scratch or chip your windshield. Additionally, pouring hot water on an icy windshield may seem like a quick fix, but it can cause the glass to crack due to the sudden temperature change.
Prevention Tip: Use a plastic ice scraper with smooth edges and avoid applying excessive force. Also, never use boiling or hot water. Instead, use a winter windshield de-icer spray or allow your car’s defroster to gradually melt the ice.
3. Road Debris and Gravel
Winter road treatments often involve salt, sand, and gravel. These materials can be kicked up by passing vehicles and hit your windshield at high speeds, leading to chips and small cracks. Because these impacts may not be immediately noticeable, they can go untreated and worsen over time.
Prevention Tip: Keep a safe distance behind snowplows and other vehicles to avoid debris impact. Inspect your windshield regularly for minor chips and have them repaired early to prevent further spreading.
4. Hidden Weaknesses and Existing Damage
Chips and small cracks from earlier in the year may seem stable, but winter weather can quickly turn them into bigger problems. Freezing moisture that seeps into cracks expands and contracts, causing the damage to worsen. Even tiny imperfections can grow under the stress of icy conditions.
Prevention Tip: If your windshield has any visible damage—no matter how small—get it inspected by a professional. At Auto Glass Hammond, we can evaluate whether a repair or replacement is necessary before the damage gets worse in cold weather.
5. Snow Accumulation and Heavy Ice
Heavy snow and ice sitting on your windshield can put excessive pressure on the glass. This can lead to stress fractures, especially if your windshield already has structural weaknesses. Improperly removing snow by pounding or hitting the glass can also cause damage.
Prevention Tip: Use a soft-bristle snow brush to clear your windshield and roof. Start at the edges and work your way inward, avoiding any harsh scraping or banging. Make it a habit to remove snow before starting your drive to avoid additional stress on the glass.
6. Faulty or Worn Wiper Blades
In winter, your wiper blades play a crucial role in maintaining visibility, but if they are cracked or hardened from the cold, they can streak or scratch the windshield. Ice buildup on the blades can also cause them to skip or apply uneven pressure.
Prevention Tip: Switch to winter-grade wiper blades designed for snow and ice. Keep them free of ice buildup and replace them at the first sign of wear. Also, use washer fluid that won’t freeze in low temperatures.
Why Prompt Windshield Repair Matters in Winter
Ignoring small chips or cracks in the colder months can lead to more expensive repairs or full windshield replacements later on. Damage tends to spread faster in winter due to the expansion of freezing water and increased pressure on the glass. A damaged windshield also compromises the structural integrity of your vehicle and may hinder proper airbag deployment in the event of an accident.
