Your Sub Has Insurance. That Doesn’t Mean You’re Covered.

Your subcontractor handed you a certificate of insurance.

You filed it. You feel covered.

You might not be.

Here’s the part most contractors learn the hard way: a certificate of insurance is not coverage. It’s a snapshot — a piece of paper that says a policy existed on the day it was printed. It doesn’t promise that policy protects you. And when a sub’s work causes an injury or damage on your job, the distance between “they had insurance” and “their insurance actually responds for me” is exactly where contractors get buried.

Let’s walk through where it breaks.

1. You were never actually added to their policy

The whole point of requiring a sub’s insurance is risk transfer. When their work causes a claim, their policy should answer — not yours.

That only happens if you’re named an additional insured on their policy, for both ongoing and completed operations.

A certificate can say additional insured. That doesn’t mean the endorsement was ever issued. The words on the certificate and the actual endorsement on the policy are two different things — and only one of them counts when there’s a claim.

2. Their coverage isn’t “primary”

Say you are properly added. Good.

Now whose policy pays first?

Without primary and non-contributory wording, both policies can get pulled in together — which means your insurance, your loss history, and your renewal premium can get dragged into a claim that was never yours to begin with.

You didn’t cause the loss. You just paid for it.

3. Their carrier can come after you

Here’s one almost nobody thinks about.

After a sub’s insurer pays a claim, it can turn around and try to recover that money from whoever it believes was at fault — and that can include you. It’s called subrogation.

A waiver of subrogation in your favor closes that door. Without it, you can be on the right side of a claim and still get a bill.

4. The certificate is a photograph, not a live feed

A COI is true the day it’s issued.

Policies get cancelled. Coverage lapses. Limits get eroded by other claims.

If a sub’s policy quietly expires three months into a six-month job and nobody catches it, the certificate in your file is worth about as much as the paper it’s printed on — and you won’t find out until the moment you need it.

So what actually protects you?

Not the certificate. The verification.

The contractors who don’t get burned all do the same unglamorous things:

• They set their insurance requirements before they hire — in writing, in the subcontract.
• They confirm the actual endorsements exist, not just that the certificate mentions them.
• They check the policy dates, and re-check before renewals while the job is running.
• They keep the whole file for years, because in California a construction-defect claim can surface long after the job is done.

None of that is hard. It’s just easy to skip — until the one time it isn’t.

A certificate tells you a sub had insurance. Only verification tells you it protects you.

Don’t leave it to the certificate.
