This is Post 6 in our hail damage series for Hinsdale, Downers Grove, Clarendon Hills, Darien, Burr Ridge, La Grange, Hodgkins, Willowbrook, Oak Brook, and Brookfield drivers. [Missed Post 5? See how collision centers and PDR shops compare.]
You got an initial estimate. Then your chosen shop took a closer look, and the number changed — usually upward. If that’s caught you off guard, you’re not alone. This is one of the most common points of confusion in the hail claims process, and it’s worth understanding why it happens before it happens to you.
It Usually Comes Down to What the First Estimate Could — and Couldn’t — See
As we covered in Post 2, a quick daylight or driveway inspection often misses dents that only become visible under proper PDR lighting. So when a specialized shop does a full evaluation, it’s common for the dent count to increase simply because more damage becomes visible under the right conditions — not because anyone did anything wrong the first time around.
Common Reasons the Estimate Changes
Hidden dents. Dents near trim, moldings, or roof rails are easy to miss in a fast inspection and often only appear once those areas are properly examined.
R&I operations. “Remove and reinstall” — some parts (moldings, antennas, weatherstripping) need to be temporarily removed to access and repair the panel underneath, which adds line items that weren’t part of the original estimate.
Molding and trim removal. Similar to R&I, this is often necessary for a proper repair but isn’t always accounted for in a first look.
Re-inspections. If your insurer requires a second look before approving additional costs, that’s a normal checkpoint in the process, not an obstacle.
Why Supplements Are Normal, Not a Red Flag
A “supplement” is simply an updated estimate submitted after more damage is found or more accurate documentation is available. It’s a standard part of the hail claims process — especially for a damage type like hail, where the full extent often isn’t clear until a vehicle is properly inspected. If your shop submits a supplement, it generally means they’re being thorough, not that costs are being inflated.
What You Can Do to Stay Ahead of It
- Ask your shop to walk you through what changed between the initial and updated estimate, line by line.
- Keep copies of every estimate and supplement — it makes any conversation with your insurer clearer and faster.
- If a supplement is submitted, ask your shop for a realistic timeline on insurer approval, so you know what to expect.
