The umbrella is a layer, not a ceiling
An umbrella sits above your home and auto liability and has its own limit. When the exposure justifies more than a single umbrella provides, an excess policy sits above it, sometimes with a different carrier. Households frequently assume an umbrella is unlimited protection, and it is simply the second floor of the building.
Each layer must attach to the one below
A tower only works if every layer attaches at the point the one beneath it ends, with no gap. Changing a middle layer without adjusting the ones above is how a structure develops a hole, and that hole is invisible until a claim passes through it.
The right total follows the exposure, not a round number
Net worth outside protected accounts, the property, the pool, the grounds, staff, vehicles, young drivers and anything commercial all inform the figure. Several million is ordinary at this level, and the number should come from the analysis rather than from a brochure.
