Why Does A Windshield Chip Turn Into A Full Crack?

A small chip in your vehicle’s windshield may not seem like more than a cosmetic issue, especially if it is out of your direct line of sight when you’re behind the wheel. You might think that it’s not worth the hassle of scheduling windshield repairs in Burnaby, BC. However, what begins as a small chip can quickly grow to a large crack that compromises the safety and structural integrity of your vehicle.

Why You Should Address Windshield Damage Immediately

Think of a chipped windshield like the tip of the iceberg. What appears small and harmless can actually be a big hazard lying in wait. Scheduling professional repairs right away can prevent a windshield crack from spreading, so you can stay safe. Not only will you prevent a bigger crack from forming, but you can also save money. Windshield repairs are much more affordable than full windshield replacement, and they can be done much more quickly. 

The Causes of a Windshield Chip Turning Into a Crack

A windshield chip creates a vulnerable weak spot in the structure of your windshield. External forces can put pressure on that area, causing the damage to spread. What starts as a small blemish from a stray pebble could grow to a crack spanning the width of the entire windshield. Common forces that can worsen a windshield crack include:

  • Moisture – In Burnaby, BC, you can expect frequent heavy rainfall throughout the year. That is not good news if you have a chipped windshield. Windshields are made from laminated glass, which means they are comprised of two layers of glass with a sheet of vinyl between them. When moisture penetrates between the layers of glass, it can quickly accelerate damage and lead to a larger crack.
  • Temperature Fluctuations – When it’s cold outside, you’ll likely run your heater to stay comfortable and warm inside the vehicle. Alternatively, summer temperatures will have you blasting the AC. This significant variation in temperatures inside and outside the vehicle can put pressure on the glass, causing it to expand and contract. If there is already a weak spot in the windshield in the form of a small chip, this movement may be too much for the windshield to handle, and the damage will spread.
  • Bumps and Braking – Bumps, potholes, and uneven surfaces will cause vibrations in your vehicle that can constantly put pressure on your damaged windshield. Braking too hard can also cause stress.

Risks of Ignoring a Chip in Your Windshield

Along with risking irreparable damage to the windshield that will require full replacement, ignoring a small chip in the windshield can present numerous other risks as well. For example, if you are in an accident and the windshield is already damaged, it will not retain its full structural integrity, so the damage from the accident may be amplified. You may also find that damage becomes worse at an inopportune time—you might find that your vehicle is inoperable due to a large crack that you notice as you’re heading out to work.

Preventing a Small Chip From Turning Into a Crack

The best way to prevent minor damage from escalating is by regularly inspecting your windshield and seeking repairs at the first signs of damage. Some helpful tips for preventing damage in the first place include:

  • Lower your speed when driving over speed bumps, potholes, or uneven road surfaces.
  • Park your vehicle indoors or in a covered parking space when possible.
  • Do not drive during extreme weather conditions if possible, especially during hail or ice storms.
  • Use the right tools for defrosting or deicing your windshield during the wintertime.
