Your vehicle’s windshield keeps wind, precipitation, and debris out of your face and the interior of the vehicle when driving. However, it doesn’t last forever. Knowing when to repair or replace a windshield improves your safety and comfort on the road. Discover how long you should go before replacing a windshield so you can stay safe behind the wheel.
Why the Windshield Matters
Your vehicle’s windshield maintains the structural integrity of the car. For instance, in the event of a rollover accident, the windshield can provide up to 45 percent of the car’s structural strength. Plus, it supports airbag deployment.
A compromised windshield affects your visibility and puts you and your passengers at risk during collisions. That’s why addressing signs of damage, whether small chips or larger cracks, is important for safety.
Can You Repair Instead of Replace Your Windshield?
Sometimes, the damage to your windshield doesn’t warrant a full replacement. Chips and minor cracks are easy to repair, saving you from relinquishing your vehicle and paying a high fee.
However, damage can vary in severity, and knowing when to repair versus replace is essential for your vehicle’s safety. If you’re unsure, a professional can determine whether repair or replacement is better. Here are some general rules for windshield replacements.
- If the chip is smaller than a quarter coin or the crack is less than three inches long, it’s likely repairable.
- Chips directly in the driver’s line of sight can obscure your view and are harder to repair without leaving some distortion.
- Windshield damage that reaches the inner layer of glass typically requires a full replacement.
- If a crack grows or spreads, replacement is often the best solution.
Factors That Determine When To Replace a Windshield
There’s no universal timeline for windshield replacements, but certain situations demand immediate attention. Take these factors into account to know when the time has come for a replacement:
Visible Cracks and Chips
A single crack or chip may not seem like a big deal, especially if it doesn’t obstruct your view. However, these imperfections can weaken the entire windshield. Untreated cracks due to weather changes or road vibrations may spread and worsen.
If you notice any cracks longer than six inches or multiple chips in close proximity, it’s time for a windshield replacement.
Obstructed Vision
If discoloration, chips, or cracks negatively affect your view while driving, that’s a definite red flag. Your ability to see the road ahead clearly impacts everyone on the road. Driving with a damaged windshield that limits visibility can lead to accidents, so prioritize prompt replacement.
Compromised Structural Integrity
Even if your windshield is intact after an accident, its integrity could be compromised. Hairline fractures and weakened bonds might not be visible, but the auto glass can shatter upon impact.
If your car has been in a fender-bender or worse, don’t rely solely on appearances—hire a mechanic or auto body professional to inspect the windshield.
Weather Conditions
Extreme weather can worsen windshield damage. Freezing temperatures can cause cracks to expand, while hot weather can intensify existing weaknesses. If you live in an area with extreme weather, regular windshield inspections can help you stay ahead of weather-induced damage.
Aging or Wear
Over time, your windshield can develop imperfections due to prolonged exposure to debris, road grime, and UV rays. They might not be as noticeable as cracks or chips, but they can still cause light to scatter across the surface, creating a distracting glare.
If your vehicle has had the same windshield for 5–10 years, it may be time for a replacement, even if there’s no visible damage.
The Risks of Delaying a Replacement
Procrastinating a windshield replacement isn’t harmless. Here’s why waiting too long can backfire:
- A compromised windshield may fail to protect you and your passengers in the event of a collision or rollover.
- Cracks and chips don’t affect the appearance of the auto glass. Also, they can refract light, especially at night, putting you at risk of accidents.
- Driving with a visibly damaged windshield is illegal in many US states and could lead to fines.
- A small crack today can turn into major damage tomorrow, increasing the complexity and cost of replacement.
How To Maintain Your Windshield and Prolong Its Life
No windshield lasts forever, but yours will serve you well for years with regular care. By following these simple steps, you can extend the life of your windshield and reduce repair or replacement costs.
- A quick repair now can save you from a full replacement later.
- Protect your windshield from direct sunlight and falling debris by parking in garages or shaded areas.
- Don’t blast hot air on a frozen windshield or pour hot water to defrost it. Sudden temperature fluctuations can crack the glass.
- Avoid ammonia-based cleaners that can damage tinting and degrade seals.
- Old, damaged wipers can create scratches and wear down your windshield.
What To Expect From the Replacement Process
If it’s time for a windshield replacement, you might be wondering what lies ahead. Most replacements take one to two hours, so it’s a relatively quick process. Here’s a quick walkthrough of the process:
- A certified technician will examine your vehicle’s windshield to confirm that a replacement is necessary.
- The technicians will carefully remove the damaged windshield to avoid interfering with the frame or surrounding structure.
- They will clean and prep the frame area to support adhesion.
- The technicians will install a new windshield using advanced sealants to create a secure and sturdy fit.
- The adhesive needs time to set, so you may be advised to avoid driving for a few hours following the replacement.
