Is there anything I can do with this roof?

[Bienes Raices]

In order to not have problems insuring it, is it possible to convert the flat part of the the roof to a sloped roof? Does anyone have an idea of how much this costs? I will of course get in touch with roofers for quotes if this looks like a good idea, but I'm trying to get an idea of how much this would cost, and whether it's worth pursuing. Thanks.
