Yes. If your underlying general liability policy names a party as an additional insured, your umbrella policy must extend that same status — otherwise you have a gap that will surface at the worst possible time. General contractors, property owners, and developers require additional insured (AI) status on both your primary GL and your umbrella, and they will reject your certificate of insurance if the umbrella does not comply.
Why Additional Insured Status on the Umbrella Matters
Additional insured status gives the named party — typically a GC or building owner — the right to tender claims to your policy as if they were a named insured, but only for liability arising out of your work. When a claim exceeds your primary GL limit, the additional insured needs the umbrella to respond on their behalf as well. If your umbrella does not extend AI status, the additional insured is covered only up to your primary $1,000,000 per-occurrence limit. Any amount above that falls on them — and they will pursue you for it.
Consider a real-world scenario. A pedestrian is injured by falling debris during a commercial tear-off. The property owner is named as an additional insured on your GL. The claim settles for $2,800,000. Your GL pays $1,000,000. If your umbrella extends AI status, it pays the next $1,800,000. If it does not, the property owner's own policy must respond for the excess — and their carrier will subrogate against you for every dollar.
How Umbrella AI Endorsements Work
Most umbrella policies handle additional insured status in one of three ways:
Automatic follow-form. The umbrella automatically extends additional insured status to anyone who qualifies as an additional insured under the underlying GL. This is the cleanest approach and the one you should look for. No separate endorsement or certificate request is needed — if they are an AI on the GL, they are an AI on the umbrella.
Scheduled endorsement. The umbrella requires you to specifically schedule (list by name) each additional insured. This creates an administrative burden and a coverage gap risk: if you forget to schedule a GC before starting a project, they are not covered under the umbrella even if they are listed on the GL. Avoid this structure if possible.
Blanket endorsement with conditions. The umbrella provides blanket AI status but only when required by a written contract executed before the loss. This is common and generally acceptable, as most GC subcontracts are in writing. However, if you start work on a handshake before the subcontract is signed, you may have a gap.
Certificate of Insurance Requirements
When a GC or property owner requests a certificate of insurance (COI), they will typically require the following umbrella-related items:
The umbrella policy must be listed in the excess/umbrella section of the ACORD 25 certificate. The additional insured must be listed in the certificate holder section with language confirming AI status applies to both the GL and the umbrella. Many GCs also require the specific umbrella endorsement number or a copy of the endorsement itself. If your umbrella uses a scheduled AI approach, the GC's name must appear on the endorsement before the certificate can be issued.
Common Problems on Roofing Projects
The most common problem is a timing gap. You win a bid, the GC sends the subcontract, and you need a COI showing umbrella AI status within 48 hours. If your umbrella requires scheduled endorsements, your agent must contact the carrier, request the endorsement, wait for processing, and then issue the certificate. This can take 5 to 10 business days with some carriers. Meanwhile, the GC moves on to another sub.
The second common problem is umbrella policies that exclude completed operations from the AI provision. The GC is named as an AI on your GL for both ongoing and completed operations (typically via CG 20 10 and CG 20 37 endorsements). But if your umbrella AI provision covers only ongoing operations, the GC loses excess coverage for completed operations claims — exactly the claims most likely to exceed primary limits.
Work with an agent who understands these nuances and places your umbrella with a carrier that provides automatic follow-form AI status, including completed operations. It eliminates certificate delays and coverage gaps simultaneously.
