For many contractors, it's just another piece of paperwork. In reality, it's one of the most important documents on a construction project.
A Certificate of Insurance (COI) helps general contractors verify that subcontractors meet the insurance requirements outlined in the contract. Without an approved certificate, work may be delayed, payments can be held up, or you may not be allowed on the jobsite.
Understanding why contractors request Certificates of Insurance—and what they're actually reviewing—can help you avoid unnecessary delays and keep your projects moving.

Lesson 2
Certificate of Insurance Checklist Every Contractor Should Know
You receive your Certificate of Insurance.
Before you send it...
Take one minute to verify these seven items.That simple checklist can help keep your project moving.
Most Certificate of Insurance delays are caused by missing information rather than missing insurance. This checklist helps contractors verify their certificates before sending them to a general contractor or project owner.
Why Certificates Need to Meet Contract Requirements
General contractors, municipalities, developers, property managers, and large commercial customers review thousands of Certificates of Insurance every year.
They're not trying to make life difficult. They're simply verifying that your insurance meets the requirements outlined in the construction contract.
When something doesn't match, corrections are needed before the certificate can move forward.
The 7-Point Certificate of Insurance Checklist
What Contractors Should Send Their Insurance Agent
Instead of saying "I need a certificate," send:
- ✓ Certificate Holder Information
- ✓ Contract Insurance Requirements
- ✓ Job Name
- ✓ Project Address
- ✓ Deadline
The more information your insurance agency receives, the faster the certificate can usually be completed.
The Missing Endorsement That Delayed a Project
A framing contractor was scheduled to begin work Monday morning.
Friday afternoon, the GC flagged the certificate because the contract required Additional Insured, Waiver of Subrogation, and Primary & Non-Contributory wording.
Those endorsements had to be confirmed before a revised certificate could be issued. The project start was delayed while corrections were completed.

Common questions answered
Answers to Frequently Asked Questions
Why was my Certificate of Insurance rejected?
Most certificates are rejected because required information or endorsements are missing—not because the contractor has no insurance.
Does a certificate prove I meet every contract requirement?
Not necessarily. The certificate summarizes coverage, but it does not replace your policy or guarantee that every contractual insurance requirement has been met.
Can I start work if my certificate is rejected?
Many general contractors require an approved Certificate of Insurance before allowing subcontractors to begin work on the project.
What is Waiver of Subrogation?
A Waiver of Subrogation endorsement may prevent your insurer from seeking recovery from another party after paying a covered claim, when required by contract. Learn more in Lesson #4.
How long does it take to issue a Certificate of Insurance?
Simple certificates can often be issued quickly, but requests involving endorsements or contract review may take longer depending on the circumstances.
Can an insurance agent change a certificate?
An agent can accurately reflect the coverage that exists on your policy, but a certificate cannot create or alter coverage. If a contract requires an endorsement, the policy must include it.
What is the most common reason certificates are rejected?
Missing endorsements, incorrect certificate holder information, and coverage limits that don't match the contract are among the most common reasons.
What is an Additional Insured endorsement?
It extends certain protections under your policy to another party when required by contract. Learn more in Lesson #3.
What does Primary & Non-Contributory mean?
It generally addresses how your insurance responds in relation to another party's insurance when required by contract. It must be supported by the policy where applicable.
