Windshield Repair vs. Replacement: Which Option Saves You More? Rock chips and cracks happen fast on Las Vegas freeways—and deciding between repair and replacement can feel like a guessing game. At CA Auto Glass, we’ve delivered great quality work at affordable pricing for 30+ years across four convenient Las Vegas locations. This guide breaks down the safety standards, cost factors, insurance basics, and local realities so you can make the budget‑smart call without sacrificing safety.
Windshield Repair vs. Replacement: Which Option Saves You More?
The quick answer (cost‑saver snapshot)
- Choose repair when damage is small, not at the edge, and not in the Driver’s Primary Viewing Area (DPVA). Industry repair criteria (ROLAGS™ 2022) allow, for example, bullseyes ≤ 1”, combination breaks ≤ 2” (body), star breaks ≤ 3”, and cracks ≤ 14”, with added limits inside the DPVA.
- Choose replacement if the crack reaches the edge, the damage penetrates both glass layers, sits in the DPVA above size limits, or if there are multiple long cracks or contamination you can’t clear.
- Plan for ADAS: many modern cars need camera calibration after replacement, which adds time and cost but is critical for safety.
Safety first: how the standards guide your decision
ROLAGS™: the repair rulebook
The Repair of Laminated Automotive Glass Standard (ROLAGS™ 2022) spells out what can be repaired and where. It also defines the DPVA—a 12‑inch‑wide area centered on the driver and running the full height of the wiper sweep—where stricter limits apply to avoid visual distortion. If damage inside the DPVA is larger than 1 inch, or a finished pit would exceed 3/16 inch, replacement is recommended.
Structural integrity after replacement
When a windshield must be replaced, the installation isn’t just cosmetic. The federal FMVSS No. 212 standard addresses windshield retention in a crash, which is why proper adhesives, curing, and procedures matter. A correctly bonded windshield helps the vehicle structure and safety systems perform as designed.
ADAS cameras & calibration: the hidden cost you should plan for
If your vehicle has lane‑keeping, forward collision warning, or automatic emergency braking, there’s usually a camera mounted to (or looking through) the glass. After a replacement, most manufacturers require calibration so those systems “see” correctly again. Independent research shows ADAS‑related steps can add material and labor costs to a windshield job (e.g., camera removal/installation and aiming). Budget accordingly—it’s a safety item, not an upsell.
Insurance 101 in Nevada (practical, not legal advice)
- Repairs: Many insurers waive the deductible for small chip/crack repairs, because fixing early prevents costlier replacements. Check your specific policy.
- Replacements: A comprehensive deductible often applies. Ask your agent whether glass coverage has a different deductible tier.
- Don’t drive with an obstructed view: Nevada law requires a clear view through required glass; if damage compromises visibility, get it fixed—repair or replacement.
A simple, Vegas‑tuned decision tree
- Size & type
- If your chip/crack is within ROLAGS repair sizes and outside the DPVA, repair likely saves money. If it’s longer, at the edge, or inside DPVA beyond limits, replacement is the safer bet.
- Location
- Edge cracks and damage that intersects more than one edge tend to spread—lean toward replacement.
- Contamination & moisture
- Dirt and moisture inside the break reduce repair quality—if you can’t clear it, replace.
- Feature‑heavy windshields
- HUD coatings, rain sensors, antennas, and camera brackets can limit repair choices; some situations call for replacement to preserve function.
- ADAS present?
- Expect calibration with replacement; factor that into your budget and schedule.
Real‑world cost math (why “repair first” often wins)
- Repair costs less now and helps avoid full replacement later if you catch it early.
- Replacement restores full strength when damage is beyond repair criteria, protects crash performance, and prevents water/air leaks when done to standard.
- ADAS calibration is an additional line item after replacement on many vehicles—worth it for safety, but something to plan for.

Bottom line
If your damage fits ROLAGS repair criteria and sits outside the DPVA, repair is usually your cheapest and fastest safe option. When cracks are long, at the edge, in the DPVA, or affect sensors, replacement protects safety—and with proper calibration, keeps ADAS working. Either way, CA Auto Glass will show you both paths with clear pricing and top‑tier workmanship, so you only pay for what you actually need. Don’t forget to follow us on Facebook.
