My insurance company won't renew policy due to float roof and age of property

[Anjelica Allen]

Has anyone experienced this in the cook county area?

My insurance company stated they will not be renewing my property insurance policy due to my flat roof. I've had them for a year, and with in that year the company changed coverage policies.

Now every insurance company I call to get coverage from says they can't insure my duplex, because it has a flat roof and over 105 years old. 

This is my first property and im confused, most of the property in my area have flat roofs. What am i missing, I'm running out of time?
