Riverside Shop Explains Why Insurance Estimates Often Miss Hidden Damage

What Does an Insurance Adjuster Check in a Collision Repair Estimate?

Riverside, United States - July 15, 2026 / Quantum Agency /

Riverside, CA, July 15, 2026 – When vehicle owners submit to their insurance adjuster's initial estimate, they often don't know what is being evaluated or what is being overlooked. Royal Collision, an independent auto body shop, is addressing that gap with detailed consumer guidance on how insurance adjusters evaluate collision repair insurance claims and what drivers can do when an estimate does not reflect the full scope of needed repairs.

What Insurance Adjusters Are Actually Measuring

When an insurer dispatches an adjuster to assess a damaged vehicle, the evaluation centers on cost containment, not restoration quality. Adjusters working on an insurance claim from a body shop typically examine four factors: whether documented damage matches the accident report, whether labor hours align with standard industry guides, whether aftermarket parts can substitute for OEM components, and whether a damaged panel can be repaired rather than replaced.

The challenge for vehicle owners is that this process often begins with a visual inspection or a desk estimate. These do not capture hidden structural damage, triggered airbag modules, or fault codes stored in the vehicle's computer after impact. On later-model vehicles, those items frequently represent the most significant portion of the actual repair cost.

A 2018 study by the Insurance Institute for Highway Safety found that some aftermarket structural crash parts do not meet the same crashworthiness standards as original manufacturer components. This raises questions about safety outcomes when insurers specify non-OEM parts to reduce claim costs.

The Supplement Process and the Consumer's Right to Choose

When a shop's documented repair assessment exceeds the adjuster's initial figure, the difference is handled through a supplement. This is a revised claim supported by disassembly findings, diagnostic pre-scan results, photographs, and applicable manufacturer repair procedures. Insurers in California are required to respond to properly submitted supplements.

California Insurance Code Section 758.5 gives vehicle owners the legal right to select their own repair facility. Insurers cannot require a claimant to use a shop from a preferred list, and no penalty can be imposed for choosing an independent shop.

"Most customers don't realize the first estimate is a starting point, not the final answer," says Ryan Oeftering, owner of Royal Collision. "When we discover damage the adjuster missed, we document it with photos, OEM procedures, and scan data, then return it to the insurer. Our customers don't handle those calls themselves."

The shop holds no Direct Repair Program agreements with any insurer, which means its repair decisions are not subject to carrier cost controls. Roughly 95% of its customers pay only their deductible, even on repairs that require OEM parts and manufacturer-specified procedures.

What Vehicle Owners Should Confirm Before Authorizing Repairs

Consumer advocates and collision industry professionals generally recommend that vehicle owners confirm three things before authorizing any collision repair: what parts will be used, who manages insurer communication, and whether the shop provides a written warranty. Insurers do not warranty collision repairs; that obligation belongs to the repair facility.

Royal Collision backs all repairs and paint with a Limited Lifetime Warranty for the life of vehicle ownership.

An Independent Collision Center Can Close the Gap on Repair Estimates

Vehicle owners who have received a collision repair estimate they believe is incomplete are not required to accept it or proceed through an insurer-preferred shop. California drivers have a statutory right to choose any licensed body shop regardless of insurer preference.

An independent assessment from a shop that manages the supplement and auto insurance claim repair process directly can close the gap between an insurer's opening figure and the cost of a proper repair.
