Lemonade insurance wants me to replace my perfectly good condition roof in order to renew. Is this normal? CA

Time for me to renew my homeowners insurance, SFR in California. Roof is original from 1999. Lemonade is telling me they will non-renew my policy unless i replace a perfectly good roof. yes it’s old but i’m in socal where it is dry. I have not seen a single house in my subdivision needing a roof replacement or even repair in the 10 years i’ve lived here.
