Why Roofing Contractors Need a Commercial Umbrella Policy
By Josh Cotner
The Certificate That Comes Back Rejected
You submit your certificate of insurance to a general contractor for a commercial roofing bid. A few days later: "Your umbrella limit is too low — we require $5M. Resubmit when it's fixed."
For roofing contractors bidding commercial work, umbrella coverage isn't optional — it's a bidding requirement. And even for residential roofers who don't work for GCs, an umbrella policy is often the most cost-effective risk management tool available.
What a Commercial Umbrella Does
A commercial umbrella policy provides excess limits above your underlying insurance — primarily general liability and commercial auto. Here's how it works:
Suppose you carry $1M per occurrence / $2M aggregate GL, and a serious completed-operations claim is brought against you for $3.5M. Your GL pays the first $1M (the per-occurrence limit). A $3M umbrella above that would cover the remaining $2.5M, up to its limit. Without the umbrella, you'd be personally exposed for the balance.
The umbrella doesn't create new coverage — it extends the limits of your underlying policies.
What Goes Underneath an Umbrella
To use an umbrella, your underlying policies must meet minimum "maintenance limits" — the required limits of underlying coverage. Most commercial umbrella carriers require:
- GL: At least $1M per occurrence / $2M aggregate
- Commercial Auto: At least $1M combined single limit (CSL)
- Workers' Comp / Employers' Liability: Standard state statutory limits + Part B limits of $500K or $1M
If an underlying policy limit is lower than what the umbrella requires, the umbrella won't drop down to fill that gap — it simply won't trigger. That's why we structure the underlying coverage first.
Why GCs and Project Owners Require High Umbrella Limits
When a general contractor hires a roofing subcontractor, they're accepting responsibility for what happens on the job site. If a roofing subcontractor causes a serious accident and only has $1M GL, and the claim exceeds $1M, the GC faces exposure beyond the sub's coverage.
This is why GCs require high combined limits — the sum of GL + umbrella — to ensure there's sufficient coverage to absorb a catastrophic claim without spilling over onto the GC's own policy.
The most common requirements from commercial GCs:
- $3M total limits (GL $1M + umbrella $2M) for smaller commercial work
- $5M total limits (GL $1M + umbrella $4M) for mid-market commercial projects
- $10M total limits (GL $2M + umbrella $8M) for large commercial or institutional projects
Umbrella Cost vs. Risk
Commercial umbrella coverage is often surprisingly affordable relative to the limit it provides. A $1M umbrella above GL and auto might add a few hundred to a few thousand dollars annually, depending on your operation's size and underlying premium.
The reason: umbrella carriers expect that most losses will be absorbed by the underlying GL and auto. The umbrella is a backstop for catastrophic events — which occur less frequently, even in high-hazard trades.
Umbrella vs. Excess Liability
You may see both "umbrella" and "excess liability" referenced in certificate requirements. There's a real difference:
- Umbrella: Follows form over the underlying policies, provides limits above them, and often broadens coverage in some ways (dropping down to fill gaps in underlying policy forms).
- Excess liability: Strictly follows the underlying policy form with no broadening, providing only additional limits without expanding coverage.
Most GC certificates that require "umbrella" actually mean umbrella or excess-following-form. Check the certificate requirement carefully before placing a strict excess policy if the GC is expecting umbrella-style coverage.
How to Read a Certificate of Insurance for Umbrella
When reviewing your own certificate, the umbrella/excess policy appears as a separate line:
- "UMBRELLA LIAB" or "EXCESS LIAB" checkbox
- Per occurrence and aggregate limits
- The "EACH OCCURRENCE" field is your per-claim limit; "AGGREGATE" is your annual total
If the GC requires $5M total limits and your GL is $1M, you need a $4M umbrella. Some certificates also ask for the umbrella to be listed on a "scheduled underlying" endorsement — we include this as standard.
Bottom Line
If you bid commercial work, you need an umbrella — it's a hard prerequisite. If you do residential work, an umbrella above your GL and auto is one of the most cost-effective ways to protect your personal assets against a catastrophic claim.
