A commercial umbrella sits on top of your general liability, commercial auto, and employer's liability limits, and picks up once a claim runs past them. Whether you need one depends on the size of the jobs you're taking on and what could actually go wrong on one of them.
A $1 million per-occurrence limit sounds like a lot until a serious injury claim, a major property damage claim, or a lawsuit with real legal costs attached shows up. On a bad job site accident, that limit can go fast, especially with a general liability policy that also has to cover defense costs within the same limit.
An umbrella typically follows the terms of your underlying policies. It won't cover something your GL specifically excludes unless the umbrella broadens that exclusion itself, and most require you carry certain minimum underlying limits before it attaches.
Bigger contracts, higher-risk trades, and a widening gap between your assets and your current liability limits are the real signals. A one-man handyman operation with a $1M GL and few assets often doesn't need one yet. A crew of ten running heavy equipment usually does.
Do most commercial contracts require an umbrella? Larger commercial and municipal jobs often do, sometimes at $2M or $5M. Worth checking the contract's insurance requirements before you bid.
How much does adding an umbrella typically cost? Less than most contractors expect relative to the added limit, but it varies by trade and current GL pricing. I can run your actual numbers.
Send me your current GL and auto limits and the size of jobs you're bidding on, and I'll tell you if there's a real gap.
