Cracked RV Windshield? Here’s How to Know if You Should Repair or Replace

Traveling in an RV offers the freedom to explore scenic routes, visit national parks, and enjoy the comfort of home on wheels. However, one common issue that RV owners face is windshield damage, particularly cracks.

While a small crack might seem insignificant, the decision to repair or replace your RV’s windshield can significantly impact your safety, convenience, and expenses. Understanding when to repair and when to replace is key to making an informed choice.

Recognizing the Damage

The first step in addressing windshield cracks is accurately assessing the extent of the damage:

• Size: Typically, cracks less than 6 inches long can often be repaired. Larger cracks may require a full windshield replacement.
• Type of Crack: Chips, stars, bull’s-eyes, and smaller linear cracks are often repairable. Large or jagged cracks may require replacement.
• Location: Cracks in the driver’s line of sight or near the edges can be problematic. Damage in these areas may impact visibility and safety.
• Spread: If the crack is actively spreading or deepening, replacement is likely necessary.

When to Repair Your RV Windshield

Repairing a crack or chip involves injecting a specialized resin into the damaged area, drying it with a UV light, and restoring the glass’s integrity and clarity. Here’s when repair is the best option:

• Small cracks or chips: If the crack measures less than 5 inches and isn’t obstructing the driver’s view, repairing the damage can be effective.
• Localized damage: Damage confined to a small area that doesn’t touch the edges.
• Cost considerations: Repairs are typically much less expensive than replacements, making them attractive if the damage qualifies.
• Time-sensitive repairs: Repair jobs often take less than an hour, allowing you to get your vehicle back on the road fast.

Benefits of repairing include preserving the original windshield, maintaining your RV’s appearance, and saving money.

When to Replace Your RV Windshield

While repairs are often sufficient for minor damage, there are clear indicators that replacement is the safer and more effective option:

• Large cracks: If a crack exceeds 6 inches, replacement is usually necessary due to compromised strength.
• Multiple cracks: Several cracks or chips close together reduce structural integrity.
• Cracks obstructing the driver’s line of sight: Damage that interferes with visibility can distort your view and pose safety hazards.
• Edge cracks: Cracks that originate or extend to the edges of the windshield are more likely to spread and weaken the structure.
• Spreading damage: Cracks that grow over time require full replacement for safety.
• Damage to sensors or cameras: Modern RVs often have integrated safety systems, also known as ADAS (Advanced Driver Assistance Systems). These rely on windshields to house sensors, cameras, or electronic components. Damage in these areas often necessitates replacement to ensure system functionality.

Safety & Legal Considerations

The safety of your RV’s structural integrity is paramount. A compromised windshield can impair visibility, especially during rain, snow, or nighttime driving. Additionally, in many regions, driving with a cracked windshield that exceeds certain limits may be illegal and result in fines or citations.

The Replacement Process

If replacement is needed, professional technicians will carefully remove the broken windshield, clean the mounting surface, apply adhesive, and install a new, manufacturer-approved windshield. Modern adhesives ensure a secure, waterproof seal—especially important when you’re driving unfamiliar roads. The replacement process typically takes a few hours, particularly if your ADAS technology needs calibration.

Preventative Tips

• Avoid following large trucks or gravel vehicles that can kick up debris.
• Park your RV in shaded or covered areas to reduce heat and UV exposure, which can weaken glass over time.
• Inspect your windshield regularly for chips or small cracks, and address them immediately.
• Use protective covers or films if parking in areas prone to falling debris.
