When a tenant renews a lease or a subcontractor returns for another project, it is tempting to treat insurance as a box already checked. You reviewed their certificate last year. You may have even read their endorsements. Nothing has changed on your side, so what could have changed on theirs?
Quite a lot, as it turns out.
Policies are rewritten every year
Each renewal is, in effect, a new policy. The carrier may change. The forms attached may change. Endorsements that were added at the insured’s request last year may not be carried forward automatically. And the certificate you receive this year may be generated from a template that was accurate for last year’s policy but not for this one.
Excess and surplus lines policies deserve extra attention
Many contractors and some commercial tenants buy coverage in the excess and surplus lines market, often called E&S. These carriers have more flexibility with their forms and pricing. In our experience, E&S carriers frequently drop additional insured, primary and non-contributory, and waiver of subrogation endorsements at renewal unless they are specifically requested again.
That means a subcontractor who fully satisfied your requirements last year can renew with the same carrier, receive a certificate that looks identical, and have none of the endorsements your contract requires.
Watch the edition dates
Every insurance form carries an edition date, usually shown as a month and year in the form number, such as 04 13 or 12 19. When the edition date on an endorsement changes from one year to the next, the wording has changed. More often than not, that change is a restriction or reduction in coverage, not an expansion.
If you have previously approved a particular endorsement, a new edition is a reason to read it again.
Carriers change, and so do their forms
When an insured moves to a new carrier, the additional insured wording can change dramatically, even if the new policy is described the same way on the certificate. One carrier may use standard ISO forms. Another may use proprietary forms with broader or narrower language. You will not see that difference on the certificate.
What a good renewal process looks like
- Track expiration dates actively. Request updated documentation before policies expire, not after.
- Request new endorsements every term. Do not assume that because the endorsement existed last year, it exists this year.
- Compare edition dates and form numbers against what you approved previously.
- Confirm the carrier and policy numbers match what the certificate shows and what the endorsements reference.
- Re-check the named parties. Ownership entities, property managers and lenders change too. Make sure this year’s requirements and this year’s endorsements reflect who needs to be covered now.
- Document what you reviewed. A record of which endorsements were verified, and when, is valuable if a claim arises later.
Why this is a system problem, not a people problem
For a single property or a single project, annual re-verification is manageable. Across a portfolio of properties or a GC’s full roster of subcontractors, it becomes a significant, recurring workload. Expirations do not line up. Some insureds respond promptly and some never respond at all. Endorsements arrive in inconsistent formats.
That is why many owners and contractors outsource coverage verification and compliance review. The value is not just in collecting certificates. It is in having someone read the endorsements, compare them to the requirements, and follow up until the gaps are closed.
Mid-term changes happen too
Renewal is not the only time coverage shifts. Policies can be cancelled for non-payment, endorsed mid-term, or rewritten with a new carrier partway through the year. The certificate in your file will not update itself when that happens, and although the certificate may list you as a holder, today’s ACORD forms state that notice of cancellation is delivered according to the policy provisions. Many policies provide no notice to certificate holders at all.
For high-risk vendors and subcontractors, consider periodic check-ins during the policy term, not just at expiration. A request for a current certificate midway through a long project is a simple way to catch a cancellation before it becomes a gap in coverage.
