COI Management Software Isn’t Enough: You Have to Verify the Policy
Most teams rely on COI tracking to confirm coverage. But COI management software can only validate what’s on the certificate—it can’t read the policy language that actually determines whether a claim will be paid. That’s the gap policy verification fills.
Why COIs Are Built to Fail
The biggest misconception in risk management is believing a COI confirms coverage. It doesn’t. It never did. A COI only summarizes. When a claim hits, people don’t go back to the COI—they go to the policy.
That’s the core of today’s risk environment. You can have all the limits you wanted, all the language you wanted, and all the endorsements you typically request, but if there’s an exclusion related to the type of work being performed, you’re left with no coverage at all.
This is not theoretical, it’s happening across the industry. Over the past few years, exclusions have become more aggressive.
COIs haven’t changed. Policies have. Jones started building its policy verification product for one reason: customers realized that COI compliance didn’t equal risk protection.
As a New York-based company serving clients in the city’s complex construction risk environment—where NY Labor Law creates unique liability exposure—we saw it repeatedly: compliant COIs hiding not only Labor Law exclusions, but also height restrictions and location exclusions.
This guide exists to show you exactly what real policy review uncovers, why exclusions hide where they hide, and how to recognize the gaps that never show up on a COI.

Understanding the Difference
What’s the difference between a COI and an insurance policy?
A COI (Certificate of Insurance)
- Usually a one-page summary
- Shows limits, carriers, dates, and basic provisions
- Does not show exclusions, definitions, conditions, or limitations
- Is not enforceable in a claim
- Is frequently outdated or incomplete
The Policy
- The full legal contract
- Defines what is actually covered
- Contains exclusions, endorsements, definitions, and conditions
- Is the only document used to determine claims outcomes
Is a COI enough to confirm coverage?
No. A COI cannot show exclusions, geographic limitations, or hidden clauses buried in endorsements. Policies contain exclusions and conditions that never appear on a COI—meaning compliance on paper can collapse the moment a claim is filed.
A COI is proof a policy exists. A policy is proof of what the insurer will actually pay. That’s why effective COI tracking requires policy review—not just certificate validation.
Policy Exclusions Explained
These exclusions are common, high-impact, and never appear on COIs.
| Exclusion | What It Removes | Real-World Impact |
|---|---|---|
| Height | Work above specific heights | Any work performed above the policy’s height limit may be uninsured. |
+ Learn more
What is a Height Exclusion?
A policy restriction removing coverage for work performed above a certain height. Common thresholds: 3 ft, 15 ft, 30 ft, or “any work above ground level.”
Why it matters
Most elevation work is high-severity risk. If a subcontractor performs any work above the limit, the insurer can deny coverage—even if the COI shows full GL limits. We found a subcontractor whose COI showed full GL limits and all required endorsements. The policy review uncovered a height exclusion: any work over 3 ft wasn’t covered.
The exclusion wasn’t labeled “height restriction”, it was hidden inside a Designated Work endorsement schedule box.
Where it hides
- Work Height Exclusion
- Designated Work Exclusion
- Designated Operations Exclusion
| Residential | Work done on residential properties | Projects may lose coverage entirely if they fall outside the policy’s residential scope. |
+ Learn more
What is a Residential Exclusion?
A policy restriction that excludes or caps coverage for work on residential properties—such as single-family homes, apartments, condominiums, or multi-family dwellings.
Why it matters
Residential projects often have higher exposure to claims. Insurers use these limitations to restrict coverage by property type or by the number of units. In one of our reviews, a COI showed complete coverage: full limits, Additional Insured, Primary & Non-Contributory, Waiver of Subrogation.
When we reviewed the full policy, we found a Residential Construction Limitation that excluded projects over 25 residential units. If a claim had occurred on a 40-unit project, the COI would have offered zero protection to our customer.
Where it hides
- Residential Exclusion
- Residential Construction Limitation
- Condo Conversion Exclusion
- Classification Limitation Endorsement
| Designated Operations/Work | Any work outside the schedule box limits | Coverage applies only to the operations listed: any work outside that scope may be excluded. |
+ Learn more
What is a Designated Work or Designated Operations Exclusion?
Coverage applies only to work listed in the schedule box. Anything outside the schedule is excluded.
Why it matters
This is one of the most dangerous exclusions because it looks harmless. The endorsement title might just say “Designated Work,” but the schedule box can contain:
- Height restrictions
- Roofing exclusions
- Exterior work limitations
- Classification restrictions
We’ve already seen this play out in two different policies: In the CGL, there was a Designated Work exclusion that quietly cut off coverage for “any exterior work… in excess of 30 ft from exterior grade.” Then we looked at the umbrella and the language was even tougher: it excluded “interior work over 30 ft above the floor” and “exterior work above ground level.”
The umbrella stops paying the moment you leave the ground. Same subcontractor, same project, but two different height triggers. That’s not something you’ll ever see on a COI.
Where it hides
- Designated Work Exclusion
- Designated Operation Exclusion
- Operations Endorsements
| Labor Law | Employee injury claims (3rd party) | Hiring parties may be left responsible for employee injury claims not covered by the subcontractor’s policy. |
+ Learn more
What is a Labor Law or Action Over Exclusion?
Also known as an Injury to Employee Exclusion, it removes coverage for certain employee injury claims, particularly those involving third-party lawsuits.
Why it matters
The standard CG 00 01 policy includes an Employer’s Liability Exclusion with an exception for liability assumed through an insured contract. A Labor Law exclusion removes that exception, meaning even if you have a written indemnity agreement, the policy won’t respond to employee injury claims.
This is especially dangerous in New York, where workers can sue GCs and owners directly under NY Labor Law, so the subcontractor’s policy won’t respond. But this “New York-centric” pattern is starting to show up in other states via similar contractual liability endorsements.
Where it hides
- Third Party Action Over Exclusion
- Exclusion of Injury to Employees
- New York Employee Injury Exclusion
| EIFS | Work on structures with synthetic stucco material | Coverage may not apply to exterior work on structures where EIFS is present. |
+ Learn more
What is an EIFS (Exterior Insulation and Finish Systems) Exclusion?
A restriction related to synthetic stucco materials commonly used on building exteriors. EIFS exclusions remove coverage for work involving these materials.
Why it matters
The strict versions exclude any work performed on a structure that contains EIFS anywhere, even if the subcontractor never touches EIFS directly. If the structure has EIFS anywhere on it, any exterior work you perform on that building becomes a problem.
Where it hides
- EIFS Exclusion
- Exterior Finishing Systems Exclusion
| Designated Location | Work in specific locations | Work performed in excluded areas won’t carry any coverage, regardless of project type or trade. |
+ Learn more
What is a State, Location, or Borough Exclusion?
Policies excluding coverage for work in certain states, counties, cities, NYC boroughs, or specific addresses.
Why it matters
If your project falls inside one of those excluded areas, the policy will not respond to any claim—no matter the trade, scope, or contract language.
We reviewed a policy that had California and Colorado state operations exclusions: any work performed in those states, including work done by subcontractors, was completely uninsured. If a GC sends that vendor to California or Colorado, they’re effectively sending them to work with no coverage at all.
Where it hides
- Designated Location Exclusion
- State Operations and Work Exclusions
- Designated Operations Exclusion
- New York 5 Borough Exclusion
| Hammer Clause | Coverage when subcontractors fail required conditions | Coverage for subcontractor-related incidents can be denied or restricted if the policy’s conditions aren’t met. |
+ Learn more
What is a Hammer Clause or Conditional Coverage Warranty?
A warranty endorsement requiring subcontractors to maintain specific insurance conditions. If those subcontractors don’t meet the carrier’s requirements—such as limits, endorsements, or safety conditions—coverage for related claims can be reduced or denied.
Why it matters
Most exclusions apply to the insured or anyone working on their behalf—subcontractors, sub-subcontractors, independent contractors. A hard hammer goes further: it requires the insured to ensure their subcontractors meet specific limits and/or other insurance conditions. If a downstream sub isn’t compliant, work tied to that subcontractor may not be covered by the policy.
The general contractor doesn’t have a contract with that sub-subcontractor and can’t control whether the carrier’s requirements are met. You have zero visibility, zero control, and full exclusion of coverage if they’re not compliant. This is becoming more common and represents full exclusion of coverage for non-compliance you can’t monitor.
Where it hides
- Warranty Endorsements
- Subcontractor Insurance Requirements
- Conditional Coverage Provisions
- Hard Hammer Clause
| XCU (Explosion, Collapse & Underground) | Work involving excavation or structural disturbance | Work involving excavation, structural changes, or underground utilities may fall outside coverage entirely if XCU-type hazards are excluded. |
+ Learn more
What is an XCU Exclusion?
It removes coverage for property damage caused by explosion, collapse of buildings or structures, and damage to underground property or utilities. These are high-severity construction risks that standard CGL policies may exclude without proper endorsements.
Why it matters
Construction work frequently involves demolition, excavation, and structural modification—all activities that carry explosion, collapse, and underground damage risks. If a subcontractor’s policy excludes XCU hazards, incidents like trench collapse, utility line damage during excavation, or structural failure during renovation won’t be covered.
Many contracts require XCU coverage to be included via endorsement. Without verifying the full policy, you won’t know if the coverage actually exists or if critical construction activities remain uninsured despite a compliant COI.
Where it hides
- Explosion, Collapse and Underground Hazard Exclusion
- XCU Exclusion
- Designated Operations Exclusion
- Partial XCU Exclusions (covering only some hazards)
Spotting Exclusions
1. Do Schedule of Forms help catch exclusions?
Helpful, but only directional. Schedule of Forms tells you what endorsements exist. Only reading the endorsement tells you what they actually do. The Schedule of Forms might list “Designated Work” as an endorsement, but it won’t show you the height restriction buried in the schedule box.
2. How common are height restrictions today?
Extremely common. Appearing in both CGL and Umbrella policies, many are mislabeled—hidden under Designated Work endorsements rather than titled “Height Exclusion.”
3. How common are exclusions for silica, asbestos, PFAS/PFOA?
Pollution exclusions are standard in most CGL policies, but many policies now add absolute exclusions for specific substances. Customers specifically requested these exclusions be flagged because they impact real construction work and can unexpectedly affect construction projects.
4. How do I identify classification restrictions?
Search for:
- Classification Limitation
- “Coverage applies only to operations described…”
- Class codes limiting scope
If the subcontractor performs anything outside the listed classification, coverage doesn’t apply.
5. How do I check whether a policy excludes work in my state?
Look for:
- Designated Location Exclusion
- State Operations Exclusion
- A schedule listing addresses, ZIP codes, counties, or states
If any match your project location, coverage is removed.
6. What are common insurance compliance issues in construction projects?
Hidden policy exclusions like height restrictions and EIFS, that void coverage despite compliant COIs. True risk management requires verifying policy language against contract requirements.
Moving Beyond COI Compliance
Throughout the webinar “COIs vs Insurance Policies: Why Reviewing Policies For Exclusionary Language Matters,” the Jones team emphasizes a simple truth: a COI can be perfect while the policy removes coverage entirely.
Most teams assume the COI matches the policy. It doesn’t. Brokers don’t list exclusions. Jones full policy review focuses on what the insurer will actually pay, not what the certificate summarizes.
That’s why COI compliance is the starting line. Policy verification is where risk management actually begins.
Customers asked for policy verification because:
- They realized compliant COIs don’t guarantee real coverage
- Claims were being denied due to hidden exclusions
- They needed a reliable way to surface risks they couldn’t identify on their own

Introduction (0:00)
Welcome and thank you for everyone joining us today. This is another webinar in a series of educational and informative sessions around various insurance topics. This one is about COIs versus policies—why verifying policies for exclusionary language matters. The panel includes the Director of Risk and Compliance at Jones, who oversees auditing operations and training, and an Insurance Policy Analyst who leads the charge on reviewing full insurance policies and exclusions.
Why Policies? (1:37)
We’re now talking about policy verification a lot. Over the past few years, this wasn’t coming up in customer conversations, but now it’s becoming natural—often initiated by customers themselves because they’re realizing that verifying COIs alone is not sufficient. Companies are including policy verification in their risk and insurance programs because they understand the COI only provides a summary of coverage. The full policy reviews detailed coverage, conditions, potential gaps, and limitations that the COI simply does not show.
The Claims Reality (3:12)
Here’s the flow: A COI is provided by a subcontractor, reviewed, and becomes compliant. You hire that subcontractor to perform work. Then an accident happens—maybe an employee falls off a ladder during the project. A claim happens, and when that claim happens, people don’t go back to the COI. That’s not how claims are settled. They go to the policy. The policy is reviewed, and a lot of coverage is revealed. Many times, unpleasant surprises come up. Imagine you realize that subcontractor had a policy with a height exclusion stating that any work in a building or structure over 3 feet is not covered by that CGL policy. They had all the limits you wanted, all the language, all the endorsements—but none of them mattered because they had an exclusion related to the type of work being performed. You’re left with no coverage at all.
How Often Does This Happen? (4:52)
It’s happening more and more often. A year and a half ago, we started building the knowledge and product to support policy review because we were seeing opportunity—people were talking about these claims where they had compliant COIs, were doing their job tracking certificates, but still that wasn’t sufficient to protect them. This significantly improved when we started working with more general contractors, where claims happen all the time. We realized this is a big pain point that a lot of people are facing.
Endorsements: Helpful vs Harmful (6:08)
There are endorsements that are typically part of COI review—Additional Insured endorsements, Waiver of Subrogation, Primary and Non-Contributory. These are common in contracts and people are used to providing them attached to a COI. However, if you ask for a Designated Work endorsement or Limitation endorsement, they’re not going to know what that is because that’s not typical practice to provide with a COI. These endorsements are part of the policy, but they’re not going to provide endorsements that exclude coverage. The COI states what applies—it doesn’t state what the policy doesn’t cover.
Real Case: Residential Construction Limitation (11:08)
We have real examples from the Jones system. A construction company had requirements for $1M CGL, Primary, Waiver of Subrogation, and Additional Insured endorsements. They got compliant with that. The COI showed CGL, Auto, Umbrella, Workers Comp—all limits were perfect, dates were good, language was necessary, endorsements were attached. Perfect. They were compliant. This was for a home building general contracting company customer. They got approved and were likely hired. Once this GC started doing policy review, we noticed they had a problematic gap. When we reviewed the policy, we found a residential exclusion evidenced on page 63. The exclusion stated: “This insurance does not apply to bodily injury, property damage, or personal advertising injury arising from your work performed by the policyholder or anyone they hire—on a townhome, residential cooperative, residential condominium project, or residential housing project if the total number of individual residential units is greater than 25.” Coverage is excluded for this specific situation. Even though they have all the limits, all the Additional Insured endorsements, all the relevant provisions—if they’re working on projects with individual residential units over 25, they have no coverage.
Real Case: Height and EIFS Exclusions (17:10)
An installation and contracting company—a subcontractor involved in a high-risk project—had a compliant COI. GL, Auto, Workers Comp, Certificate Holder, Additional Insured, all perfect. When we reviewed their policy, we were surprised with a couple of gaps. In the general liability policy, they had a height restriction and an EIFS exclusion—both big deals for this type of company. The COI showed everything perfectly, but the policy had these exclusions. On page 73, we found a Designated Operations exclusion. In the schedule box, they were describing “any exterior work on any building or structure which requires work in excess of 30 ft from exterior grade.” Any work related to this level of height is excluded from coverage.
EIFS Exclusion Details (19:48)
On page 75, we found the Exterior Insulation and Finish Systems exclusion. This is very common but might not apply for all subcontractors. For this specific one working with installation, it really applies. The insurance does not apply to bodily injury or property damage if the work is directly related to the exterior insulation finish system—design, manufacture, construction—or if you’re working with any exterior component used in a structure where exterior insulation and finish system exists. It’s not only if you’re working directly with EIFS, but if you’re also doing work on a structure that has it, that’s also a problem.
Full vs Partial Policy Verification (30:33)
We have two ways of addressing policy review. Full policy verification means reviewing everything—telling you they have maybe 10 exclusions. It doesn’t mean for every project these exclusions are problematic. We’re giving you everything we find in the policy that’s problematic—any exclusions, provisions, clauses, even definitions. We review the whole thing, and if it limits coverage for the additional insured, we flag it as a gap. Customers have the ability to override exclusions that don’t present material risk to the project or job scope. When we’re doing full policy verification, we’re looking at everything—over 30 items for sure. Partial policy verification is a more strategic way. We’re collecting full policies, but customers pick up to five items—five exclusions or endorsements they want us to review.
Absolute EIFS Exclusion (42:48)
Sometimes exclusions lurk in a small sentence here and there and change entire coverage. The normal ISO EIFS exclusion states: your product or work with respect to any exterior component, fixture, or feature is excluded if any exterior insulation finish system is used on that part of the structure containing the component you used. But the absolute one changes—any work or operations with respect to an exterior component, fixture, feature of any structure if EIFS is used on any part of that structure. You don’t need to be working directly in the part that has EIFS—if EIFS is anywhere on that structure, coverage doesn’t apply to that work.
Hard Hammer Clause (45:07)
Most exclusions say it applies to the insured or anyone working on behalf of the insured—subcontractors, sub-subcontractors, independent contractors. Sometimes there’s a warranty endorsement asking the sub-subcontractor to comply with a series of insurance requirements. The carrier asks for a COI with specific limits and endorsements, and if that sub-subcontractor is not compliant, work is not going to be covered by the policy. Because the general contractor doesn’t have a contract with that sub-subcontractor and can’t know the requirements of the carrier, you have no control on whether those sub-subcontractors are compliant. More often we’re seeing that coverage does not apply—it’s full exclusion of coverage if they’re not compliant.
Classification Limitation (49:03)
When you go into a general liability policy, there’s going to be classification of work performed by the subcontractor. Let’s say the classification is for interior painting, and if you’re not looking closely, they end up doing more than interior painting—they do exterior painting as well. Sometimes they have a classification limitation saying this insurance applies to your ongoing operations and completed operations only for specific work as described and scheduled below. If the subcontractor is not doing the work specifically described in the schedule of their classification, coverage is not going to apply.
Schedule of Forms: Enough? (52:46)
We consider schedule of forms part of the policy review process. When you’re looking at schedule of forms, you’re identifying all these endorsements that could be problematic and have a sense of where you need to look. However, schedule forms could hide a bunch of scary exclusions that you’re not going to see the name there in the title. Example: the umbrella policy said “height restriction,” but the title was not height restriction—it was Designated Work. You would only see in the schedule of forms “Designated Work Exclusion” but you need to go into the policy and into the schedule box of the endorsement to find out there’s a height restriction.
Risk Transfer Framework (55:39)
We’re talking about policies and why reviewing policies is important, but we need to think about the process of transferring risk. The first thing you do is identify in your projects where you have exposure, where you have liability. It doesn’t matter if you’re reviewing policies and COIs if you’re not doing the second step: creating written contracts with hold harmless agreements, indemnification statements, and insurance provisions. A lot of the language in COIs and policies is important to vet, but a lot of that language goes back to the contract. If the contract doesn’t exist, it opens people to liability. There are different levels of effort to manage risk. It’s important you understand that having that certificate of insurance with the language you wanted, with the names of the additional insured, does not actually protect you as you think if you don’t have a written agreement.
