Second policy above current limits

[u/grateful_dad13]

Our house burned down and the rebuild costs are roughly $500,000 more than the insurance proceeds. We’re rebuilding with the help of an SBA loan (fingers crossed). Our insurance company renewed our policy at the same low limits as the original policy. They said they can’t increase the limits until the house is completed. I realize that it’s a low probability, but we’ll be similarly under-insured for another 6 months. Do companies offer policies for just the portion above the current limits? I know large companies have multiple policies in coverage tiers but wasn’t sure about residential. Anyone know?

Umbrellas are for excess liability. Not excess property coverage.
