What Are the Key Differences Between Coverdash and Harper Umbrella and Excess Liability Insurance?

Buying Online Versus a Guided Review

Your landlord’s new lease demands more liability than your primary policy carries, and you need proof fast. Coverdash, a broker, runs quote to purchase digitally on top of the policies you already have. Harper takes your request online or by phone, and a specialist reviews your underlying policies and maps which ones sit under the layer. Choose Coverdash if you know the limit you need and want it done today; choose Harper if you have several policies and want someone to check for gaps between them. ¹ ² ⁴

What the Layer Sits Over

Coverages match closely. Coverdash’s layer kicks in when a large claim exhausts general liability, commercial auto or the employer’s liability in your workers’ compensation policy. Harper’s responds over general liability, auto liability and an injured employee’s separate lawsuit, and it follows the terms of the policies underneath. ¹ ⁴

Deciding How Much to Buy

Harper gives practical guidance: buy when a lease or contract requires it, otherwise weigh how much of a claim you could absorb. It adds that each extra million usually costs a fraction of the first. Coverdash lists Umbrella and Excess Liability as separate products without explaining the difference. Neither publishes limits. ⁴ ³ ¹
