My insurer will only replace the damaged part of my siding, so it won't match. Do they have to replace all of it?

In short
- Some states have a rule about matching. California is one.
- Read your policy and your state's rule. Then write to the insurer.
- If you still disagree, ask about appraisal or file a complaint with your state.
What this means
There is no single national rule. It depends on your policy and your state. California has a clear rule for replacement cost claims. If new items do not match the old ones in quality, color, or size, the insurer must replace all items in the damaged area so they look reasonably uniform [1]. A national model rule written by state regulators (NAIC) says the same thing and adds that it covers inside and outside losses [2]. A model rule only applies in a state that has adopted it. Whether your state did is "Don't know yet" here.
What you can do: tell the insurer in writing why you disagree, and send proof, like a contractor's estimate or photos of the mismatch. The Texas Department of Insurance says the company "may have overlooked something" and may adjust [3]. If you still disagree, your policy may have an appraisal process. Each side hires an appraiser, and an umpire decides if they differ [3]. You can also file a complaint with your state insurance department [3].
Your next step
Write to your adjuster, name the mismatch, and attach photos and a contractor's estimate. Ask the insurer to point to the policy words it used. The sources give no deadline for this; check your policy for any deadline to demand appraisal.
Check it yourself
Read the "Loss Settlement" and "Appraisal" parts of your policy. Check your state insurance department's site for a matching rule. Outside California, the sources here do not say which states require matching — "Don't know yet".
